专题16 科普类说明文 ‎2019高考题 D【2019·全国I】‎ We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(装置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.‎ To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 2019. And MP3 players, smart phones, and LCD TVs entered homes in 2019, before tablets and e-readers showed up in 2019.‎ As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2019. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2019 window.‎ So what's the solution（解决方案）? The team's data only went up to 2019, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.‎ ‎32. What does the author think of new devices?‎ A. They are environment-friendly. B. They are no better than the old.‎ C. They cost more to use at home. D. They go out of style quickly.‎ ‎33. Why did Babbitt's team conduct the research?‎ A. To reduce the cost of minerals.‎ B. To test the life cycle of a product.‎ C. To update consumers on new technology.‎ D. To find out electricity consumption of the devices.‎ ‎34. Which of the following uses the least energy?‎ A. The box-set TV. B. The tablet.‎ C. The LCD TV. D. The desktop computer.‎ ‎35. What does the text suggest people do about old electronic devices?‎ A. Stop using them. B. Take them apart.‎ C. Upgrade them. D. Recycle them.‎ ‎【答案】32. A 33. D 34. B 35. A ‎【解析】本文是一篇科普说明文。文章讲述了新旧电子设备的差别，旧电子设备耗能高，不环保。所以作者主张使用新电子设备。‎ ‎33. 细节理解题。根据文章第二段中的To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life 可知，Babbitt’s team研究的目的是弄清楚这些设备用了多少电。故选D。‎ ‎34. 细节理解题。根据文章最后一段中的They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.可知，平板电脑是耗能最少的电子设备，可以降低44%的耗能。故选B。‎ ‎35. 推理判断题。根据文章的整体内容可知，因为旧的电子设备耗能高，不环保。所以作者建议停止使用旧的电子设备。故选A。‎ 点睛：熟悉比较句型是彻底理解本文的关键，也是解题的关键。本文中的比较句型：‎ ‎1. That’s bad news for the environment – and our wallets – as these outdated devices consume much more energy than the news ones that do the same things 做同样的事，旧的过时的装置比新装置消耗更多能源，对环境有害，浪费钱财。‎ ‎2. According to the analysis of Babbitt’s team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions (排放) more than doubling during the 1992 to 2019 window.‎ 根据Babbitt团队的分析，旧的桌面监视器和阴极射线管箱式电视机是最差的电子设备，它们的耗能和温室气体的排放是1992到2019window的两倍还多。‎ ‎3. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.他们发现在平板电脑上看的随需变化的娱乐节目比在电视和电脑上看耗能减少了44%。 ‎ B【2019·浙江】‎ ‎ Steven Stein likes to follow garbage trucks. His strange habit makes sense when you consider that he’s an environmental scientist who studies how to reduce litter, including things that fall off garbage trucks as they drive down the road. What is even more interesting is that one of Stein's jobs is defending an industry behind the plastic shopping bags. ‎ ‎ Americans use more than 100 billion thin film plastic bags every year. So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts(收银台) . The bags are prohibited in some 90 cities in California, including Los Angeles. Eyeing these headwinds, plastic-bag makers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume.‎ ‎ Among the bag makers' argument: many cities with bans still allow shoppers to purchase paper bags, which are easily recycled but require more energy to produce and transport. And while plastic bags may be ugly to look at, they represent a small percentage of all garbage on the ground today ‎ The industry has also taken aim at the product that has appeared as its replacement: reusable shopping bags. The stronger a reusable bag is, the longer its life and the more plastic-bag use it cancels out. However, longer-lasting reusable bags often require more energy to make. One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic.‎ ‎ Environmentalists don't dispute（质疑） these points. They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years.‎ ‎24. What has Steven Stein been hired to do?‎ A. Help increase grocery sales.‎ B. Recycle the waste material.‎ C. Stop things falling off trucks.‎ D. Argue for the use of plastic bags.‎ ‎25. What does the word “headwinds”in paragraph 2 refer to?‎ A. Bans on plastic bags.‎ B. Effects of city development.‎ C. Headaches caused by garbage.‎ D. Plastic bags hung in trees.‎ ‎26. What is a disadvantage of reusable bags according to plastic-bag makers?‎ A. They are quite expensive.‎ B. Replacing them can be difficult.‎ C. They are less strong than plastic bags.‎ D. Producing them requires more energy.‎ ‎27. What is the best title for the text?‎ A. Plastic, Paper or Neither B. Industry, Pollution and Environment C. Recycle or Throw Away D. Garbage Collection and Waste Control ‎【答案】24. D 25. A 26. D 27. A ‎【解析】文章分析了几种购物袋的使用情况，塑料袋造成了环境问题，尽管纸袋容易回收，但生产和运输需要更多的能源，希望消费者使用耐用可重复使用的袋子。‎ ‎24. 细节理解题。根据第一段one of Stein's jobs is defending an industry behind the plastic shopping bags.和第二段plastic-bag makers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume.可知塑料袋生产商雇用Steven Stein是为了证明他们的产品并不像大多数人想象的那样对地球有害，是对塑料袋被禁用的解释和争论。故选D。‎ ‎25. 词义猜测题。上文介绍在许多美国大城市塑料袋被禁用，看到这种现状，塑料袋生产商雇用Steven Stein等科学家是为了证明他们的产品并不像大多数人想象的那样对地球有害。headwinds“逆风”，此处指塑料袋被禁用的现状，即Bans on plastic bags，故选A。‎ ‎26. 细节理解题。根据第四段However, longer-lasting reusable bags often require more energy to make.可知塑料袋生产商认为生产耐用且能重复使用的袋子需要更多的能量，故选D。‎ ‎27. ‎ ‎ 标题归纳题。文章讲述了使用塑料袋造成的环境问题，纸袋容易回收，但生产和运输需要更多的能源，希望消费者使用耐用可重复使用的袋子。对这三种方式进行了对比，Plastic, Paper or Neither既能概括全文，又能吸引读者，最适合作为标题。故选A。‎ ‎【点睛】‎ 概括主旨的方法是：先看首尾或各段开头再看全文找主题句，若无明显主题句，就通过关键词句来概括(如议论文中寻找表达作者观点态度的词句，要看懂全文的主要内容，明白了主要内容就能准确概括文章标题。小题4要求概括标题，本文讲述了使用塑料袋造成的环境问题，纸袋容易回收，但生产和运输需要更多的能源，希望消费者使用耐用可重复使用的袋子。对这三种方式进行了对比，Plastic, Paper or Neither既能概括全文，又能吸引读者，适合作为标题。‎ C【2019·天津卷】‎ There’s a new frontier in 3D printing that’s beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn’t stopping there.‎ Food production With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to “re-create forms and pieces” of food that are “exactly the same,” freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed,rather than farm to table.‎ Sustainability(可持续性）‎ The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.‎ Nutrition Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, “Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday’s bread from the ‎ supermarket, you’d eat something baked just for you on demand.”‎ Challenges Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.‎ ‎46. What benefit does 3D printing bring to food production?‎ A. It helps cooks to create new dishes.‎ B. It saves time and effort in cooking.‎ C. It improves the cooking conditions.‎ D. It contributes to restaurant decorations.‎ ‎47. What can we learn about 3D food printing from Paragraphs 3?‎ A. It solves food shortages easily.‎ B. It quickens the transportation of food.‎ C. It needs no space for the storage of food.‎ D. It uses renewable materials as sources of food.‎ ‎48. According to Paragraph 4, 3D-printed food ________.‎ A. is more available to consumers B. can meet individual nutritional needs C. is more tasty than food in supermarkets D. can keep all the nutrition in raw materials ‎49. What is the main factor that prevents 3D food printing from spreading widely?‎ A. The printing process is complicated.‎ B. 3D food printers are too expensive.‎ C. Food materials have to be dry.‎ D. Some experts doubt 3D food printing.‎ ‎50. What could be the best title of the passage?‎ A. 3D Food Printing: Delicious New Technology B. A New Way to Improve 3D Food Printing C. The Challenges for 3D Food Production D. 3D Food Printing: From Farm to Table ‎【答案】46. B 47. D 48. B 49. C 50. A ‎【解析】本文是一篇科普类短文阅读。文章主要介绍了3D打印技术在食物上的应用取得了进展，但目前仍面临着许多方面的挑战。‎ ‎46. 推理判断题。根据文章Food production中叙述了没有经验的人可以用3D打印机做出复杂的巧克力雕塑和美丽的婚礼蛋糕，以及餐厅能够用3D打印出所有的菜肴和甜点，从而可以推断出3D打印的优势是节省了做饭的时间和精力。故选B。‎ ‎48. 推理判断题。根据文章第四段Food printing could allow consumers to print food with customized nutritional content, like vitamins.（食品打印可以让消费者打印定制营养的食物），从而可以推断出3D打印出来的食物可以满足个人营养需求。故选B。‎ ‎49. 细节理解题。根据文章最后一段most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad.可知，阻止3D打印食物进一步广泛使用的原因是原料必须是干的，含水多的肉和牛奶不能应用于3D打印因为很容易坏。故选C。‎ ‎50. 主旨大意题。文章主要介绍了3D打印技术在食物上的应用取得了进展，但目前仍面临着许多方面的挑战。所以用标题3D Food Printing: Delicious New Technology，故选A。 ‎ 点睛：科普类说明文历来是高考阅读理解命题的重点。本文是一篇3D打印技术在食物方面的应用，文章运用一些小标题和对一些专业词汇作了多处中文注释，降低了考生的阅读难度。文章逻辑性强，条理清楚，主要考查学生对语篇的整体把握和领悟能力以及对特定细节的认读和处理能力。最后一小题考查主旨大意，为文章选择出最好的标题。考生做此题时一定要注意选择项必须要能概括整个文章的内容，不能以偏概全。如B、C、D选择项在文章中都有所涉及，但不足以概括全文，所以需要考生正确概括全文的主旨大意。‎ C[2019•北京卷]‎ Plastic-Eating Worms Humans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills(垃圾填埋场), and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms. ‎ Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics. The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms’ chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste(糊状物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass — apparently broken down by enzymes (酶) from the worms’ stomachs. Their findings were published in Current Biology in 2019.‎ Federica Bertocchini, co-author of the study, says the worms’ ability to break down their everyday food — beeswax — also allows them to break down plastic. ＂Wax is a complex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well, ＂she explains, ＂The wax worm evolved a method or system to break this bond. ＂‎ Jennifer DeBruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But compared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes(肠道微生物)?‎ Bertocchini agrees and hopes her team’s findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process — not simply ＂millions of worms thrown on top of the plastic.＂‎ ‎43. What can we learn about the worms in the study?‎ A. They take plastics as their everyday food.‎ B. They are newly evolved creatures.‎ C. They can consume plastics.‎ D. They wind up in landfills.‎ ‎44. According to Jennifer DeBruyn, the next step of the study is to .‎ A. identify other means of the breakdown B. find out the source of the enzyme C. confirm the research findings D. increase the breakdown speed ‎45. It can be inferred from the last paragraph that the chemical might .‎ A. help to raise worms B. help make plastic bags C. be used to clean the oceans D. be produced in factories in future ‎46. What is the main purpose of the passage?‎ A. To explain a study method on worms.‎ B. To introduce the diet of a special worm.‎ C. To present a way to break down plastics.‎ D. To propose new means to keep eco-balance.‎ C ‎【文章大意】 本文是一篇科普知识类文章。从环保理念出发，文章围绕一种可以降解塑料的虫子大蜡螟展开，描述了研究进展及虫子能降解塑料的原理，即使用其胃中的酶降解塑料，为塑料污染问题提供了新的思路。‎ ‎43. C　细节理解题。根据文章第二段中的“The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it.”可知，这些虫子可以消耗聚乙烯购物袋，即塑料袋。故选C。‎ ‎44. B　推理判断题。根据文章第二段中的“The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes (肠道微生物)？”可知，下一步是探究酶的来源。故选C。‎ ‎45. D　推理判断题。根据文章最后一段“But she expects using the chemical in some kind of industrial process-not simply" millions of worms thrown on top of the plastic”可知研究者希望那些化学物品可以批量生产，而不是将许多虫子直接扔在垃圾堆里。故选D。‎ ‎46. C　写作意图题。全文都在围绕可以降解垃圾的虫子展开，文章的目的就是向读者呈现这种独特的降解塑料的方式。故选A。‎ ‎2019高考题 科普知识类 ‎ [2019·北京卷]‎ D Hollywood's theory that machines with evil(邪恶的) minds will drive armies of killer robots is just silly. The real problem relates to the possibility that artificial intelligence(AI) may become extremely good at achieving something other than what we really want. In 1960 a wellknown mathematician Norbert Wiener, who founded the field of cybernetics(控制论), put it this way: “If we use, to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere(干预), we had better be quite sure that the purpose put into the machine is the purpose which we really desire.”‎ A machine with a specific purpose has another quality, one that we usually associate with living things: a wish to preserve its own existence. For the machine, this quality is not inborn, nor is it something introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead. So if we send out a robot with the single instruction of fetching coffee, it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere with its task. If we are not careful, then, we could face a kind of global chess match against very determined, super intelligent machines whose objectives conflict with our own, with the real world as the chessboard. ‎ The possibility of entering into and losing such a match should concentrate the minds of computer scientists. Some researchers argue that we can seal the machines inside a kind of firewall, using them to answer difficult questions but never allowing them to affect the real world. Unfortunately, that plan seems unlikely to work: we have yet to invent a firewall that is secure against ordinary humans, let alone super intelligent machines.‎ Solving the safety problem well enough to move forward in AI seems to be possible but not easy. There are probably decades in which to plan for the arrival of super intelligent machines. But the problem should not be dismissed out of hand, as it has been by some AI researchers. Some argue that humans and machines can coexist as long as they work in teams—yet that is not possible unless machines share the goals of humans. Others say we can just “switch them off” as if super intelligent machines are too stupid to think of that possibility. Still others think that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, with confidence, “Anyone who expects a source of power in the transformation of these atoms is talking moonshine.” However, on September 12, 1933, physicist Leo Szilard invented the neutroninduced(中子诱导) nuclear chain reaction.‎ ‎67．Paragraph 1 mainly tells us that artificial intelligence may ________．‎ A．run out of human control B．satisfy human's real desires C．command armies of killer robots D．work faster than a mathematician ‎68．Machines with specific purposes are associated with living things partly because they might be able to ________．‎ A．prevent themselves from being destroyed B．achieve their original goals independently C．do anything successfully with given orders D．beat humans in international chess matches ‎69．According to some researchers, we can use firewalls to ________．‎ A．help super intelligent machines work better B．be secure against evil human beings C．keep machines from being harmed D．avoid robots' affecting the world ‎70．What does the author think of the safety problem of super intelligent machines?‎ A．It will disappear with the development of AI.‎ B．It will get worse with human interference.‎ C．It will be solved but with difficulty.‎ D．It will stay for a decade.‎ ‎【文章大意】 本文为科普类文章，讲的是随着科技的发展，人工智能 (AI)可能会超出人类的控制。‎ ‎67．A　段落大意题。第一段第二句说“人工智能虽然擅长完成任务，但这有可能不是我们真正想要的”。因此选A。‎ ‎【名师点睛】‎ 推理判断题属于主观题，是层次较高的题目。它包括判断题和推理题。这两类题常常相互依存，推理是为了作出正确的判断，正确的判断又依赖于合乎逻辑的推理。此类题要求在理解表面文字的基础上，作出判断和推论，从而得到文章的隐含意思和深层意思，也就是通过文章中的文字信息、上下文的逻辑关系及事物的发展变化等已知的信息，推断出作者没有直接表达的态度和观点。‎ 推理判断题的解题方法 ：‎ 推理判断题不仅要求考生读懂文章中的每个句子的意思还要推理它们之间的关系，结合自己的生活常识和经验，再通过逻辑推理和判断，理解文章的言外之意，从而揭示文章的深层涵义。‎ 任何一篇文章都有其特定的写作目的，读者需要知道如何去做或按照某种方式思考问题。推理判断题的答案不可能在文章中直接找到，因此推理时我们务必要忠于原文，在文章中寻找并确定可推论的依据，即：已知部分－推论的前提，从中推测出未知部分－推理的结论，切忌妄加评论，把自己的观点当成作者的观点。‎ ‎ [2019·江苏卷]‎ B Before birth，babies can tell the difference between loud sounds and voices. They can even distinguish their mother's voice from that of a female stranger. But when it comes to embryonic learning (胎教)，birds could rule the roost. As recently reported in The Auk：Ornithological Advances，some mother birds may teach their young to sing even before they hatch (孵化). Newborn chicks can then imitate their mum's call within a few days of entering the world.‎ This educational method was first observed in 2019 by Sonia Kleindorfer，a biologist at Flinders University in South Australia，and her colleagues. Female Australian superb fairy wrens were found to repeat one sound over and over again while hatching their eggs. When the eggs were hatched，the baby birds made the similar chirp to their mothers—a sound that served as their regular “feed me！” call.‎ To find out if the special quality was more widespread in birds，the researchers sought the redbacked fairy wren，another species of Australian songbird. First they collected sound data from 67 nests in four sites in Queensland before and after hatching. Then they identified begging calls by analysing the order and number of notes. A computer analysis blindly compared calls produced by mothers and chicks，ranking them by similarity.‎ It turns out that baby redbacked fairy wrens also emerge chirping like their mums. And the more frequently mothers had called to their eggs，the more similar were the babies' begging calls. In addition，the team set up a separate experiment that suggested that the baby birds that most closely imitated their mum's voice were rewarded with the most food.‎ This observation hints that effective embryonic learning could signal neurological (神经系统的) strengths of children to parents. An evolutionary inference can then be drawn. “As a ‎ parent，do you invest in quality children，or do you invest in children that are in need？”Kleindorfer asks. “Our results suggest that they might be going for quality.”‎ ‎58．The underlined phrase in Paragraph 1 means “________”．‎ A．be the worst B．be the best C．be just as bad D．be just as good ‎59．What are Kleindorfer's findings based on?‎ A．Similarities between the calls of mums and chicks.‎ B．The observation of fairy wrens across Australia.‎ C．The data collected from Queensland's locals.‎ D．Controlled experiments on wrens and other birds.‎ ‎60．Embryonic learning helps mother birds to identify the baby birds which ________．‎ A．can receive quality signals ‎ B．are in need of training C．fit the environment better ‎ D．make the loudest call ‎【文章大意】 本文是一篇科普说明文。文章介绍了一项新发现：幼鸟在被孵化前母鸟便教它们识别声音了。母亲呼唤它们的鸟蛋越频繁，则它们的孩子越会发出相似的声音；幼鸟的声音越像它们母亲的声音，则它们获得的食物奖励就越多。‎ ‎58. B　词义猜测题。第一段将人类婴儿与幼鸟进行了对比，画线词组所在句上文讲出生前人的辨别声音的能力很强，下文讲一些母鸟在幼鸟被孵化之前就教它们学唱歌了。据此可以判断，在胎教方面，鸟儿的表现是最好的，推测“rule the roost”意为“be the best”，故选B项。‎ ‎59. A　细节理解题。根据第二段第三句“When the eggs were hatched, the baby birds made the similar chirp to their mothers—a sound that served as their regular ‘feed me！’ call.”可知，当这些幼鸟被孵化出来的时候，它们也发出了和它们的妈妈类似的鸣叫。据此可知，Sonia Kleindorfer的发现是以母鸟和幼鸟叫声的相似点为基础的，故选A项。‎ ‎60. C　推理判断题。第四段“In addition, the team set up a separate experiment that suggested that the baby birds that most closely imitated their mum's voice were rewarded with the most food.(一项单独的实验表明模仿母鸟声音最接近的幼鸟会得到最多的食物)”和最后一段研究人员的研究结果表明，母鸟会选择 质量优良的孩子，因此可以推断，母鸟通过胎教来确定质量优良的幼鸟，即最会模仿它们声音的幼鸟。质量优良的幼鸟无需过多帮助就能更好地适应环境，故选C项。‎ ‎【名师点睛】‎ 猜测词义题概况 ‎ 词义猜测是应用英语的重要能力，也是高考必考的题型。它不但需要准确无误地理解上下文，而且要有较大的泛读量，掌握或认识较多的课外词汇。考生应学会通过构词、定义、同位、对比、因果、常识、同义、反义及上下文线索等确定词义。‎ ‎　　一、题型特点与命题方式：‎ ‎　　此类题型有逐渐增加的趋势，尤其是猜测词组、句义题。因为猜测词组、句义题涉及题材背景、句子结构、文章主旨、作者的观点态度等。联系主旨、整合上下文信息是解答这类题的关键。近几年阅读理解的生词率略有上升，加大了猜测难度。命题者着重考查考生利用同义或反义关系、构词法、语法和语篇文脉等理解生词的能力。‎ ‎　　【命题趋势】‎ ‎　　1.要求根据阅读材料所提供的信息，结合中学生应有的常识和经验，正确判断生词词组的含义或成熟词在特定语境中表达的具体含义以及一些句子的意思。‎ ‎　　2.要求猜测词义的词一般为实词及其词组，通过构词、定义、对比、因果、联想、上下文等线索确定词义的具体内容。例如第65题。‎ ‎　　3.代词复指理解题也是猜测词义的常考类型。用“逻辑关系梳理法”、“递向寻踪法”理清人物及事物之间的逻辑关系是关键所在。‎ ‎　　【设问形式】‎ ‎　　The underlined word “…” in the second(third…) paragraph refers to(means) ______.‎ ‎　　By saying that “…” in the first(second…) paragraph, the author means that ______.‎ ‎　　In paragraph …, “…” can be replaced by “______”.‎ ‎　　The meaning of “…” in paragraph… is related to ______.‎ ‎　　Which of the following has the closest meaning to…(paragraph…)?‎ The underlined sentence in the … paragraph probably means that _____.‎ ‎ 解题思路 ‎　　做这种类型的题目，要根据词、词组、句子所在的语境上下文来判断其意义。因此熟练掌握一些猜词技巧是做好这类题的关键。命题者在出这类题时惯用常规词义来麻痹考生，我们要特别注意熟词生义，切不可脱离语境主观臆断。 ‎ 考点：考查科普说明文阅读 ‎ [2019·江苏卷]‎ D Old problem，new approaches While clean energy is increasingly used in our daily life，global warming will continue for some decades after CO2 emissions (排放) peak. So even if emissions were to begin to decrease today，we would still face the challenge of adapting to climate change. Here I will stress some smarter and more creative examples of climate adaptation.‎ When it comes to adaptation，it is important to understand that climate change is a process. We are therefore not talking about adapting to a new standard，but to a constantly shifting set of conditions. This is why, in part at least，the US National Climate Assessment says that：“There is no ‘onesize fits all’ adaptation.” Nevertheless，there are some actions that offer much and carry little risk or cost.‎ Around the world, people are adapting in surprising ways，especially in some poor countries. Floods have become more damaging in Bangladesh in recent decades. Mohammed Rezwan saw opportunity where others saw only disaster. His notforprofit organization runs 100 river boats that serve as floating libraries，schools，and health clinics，and are equipped with solar panels and other communicating facilities. Rezwan is creating floating connectivity(连接) to replace flooded roads and highways. But he is also working at a far more fundamental level：his staff show people how to make floating gardens and fish ponds to prevent starvation during the wet season.‎ Elsewhere in Asia even more astonishing actions are being taken. Chewang Norphel lives in a mountainous region in India, where he is known as the Ice Man. The loss of glaciers (冰川) there due to global warming represents an enormous threat to agriculture. Without the glaciers, water will arrive in the rivers at times when it can damage crops. Norphel's inspiration came from seeing the waste of water over winter, when it was not needed. He directed the wasted water into shallow basins where it froze, and was stored until the spring. His fields of ice supply perfectly timed irrigation(灌溉) water. Having created nine such ice reserves, Norphel calculates that he has stored about 200，000m3 of water. Climate change is a continuing process, so Norphel's ice reserves will not last forever. Warming will overtake them. But he is providing a few years during which the farmers will, perhaps, be able to find other means of adapting.‎ Increasing Earth's reflectiveness can cool the planet. In southern Spain the sudden increase ‎ of greenhouses (which reflect light back to space) has changed the warming trend locally, and actually cooled the region. While Spain as a whole is heating up quickly, temperatures near the greenhouses have decreased. This example should act as an inspiration for all cities. By painting buildings white, cities may slow down the warming process.‎ In Peru, local farmers around a mountain with a glacier that has already fallen victim to climate change have begun painting the entire mountain peak white in the hope that the added reflectiveness will restore the lifegiving ice. The outcome is still far from clear. But the World Bank has included the project on its list of “100 ideas to save the planet”．‎ More ordinary forms of adaptation are happening everywhere. A friend of mine owns an area of land in western Victoria. Over five generations the land has been too wet for cropping. But during the past decade declining rainfall has allowed him to plant highly profitable crops. Farmers in many countries are also adapting like this—either by growing new produce, or by growing the same things differently. This is common sense. But some suggestions for adapting are not. When the polluting industries argue that we've lost the battle to control carbon pollution and have no choice but to adapt, it's a nonsense designed to make the case for business as usual.‎ Human beings will continue to adapt to the changing climate in both ordinary and astonishing ways. But the most sensible form of adaptation is surely to adapt our energy systems to emit less carbon pollution. After all, if we adapt in that way, we may avoid the need to change in so many others.‎ ‎65．The underlined part in Paragraph 2 implies ________．‎ A．adaptation is an everchanging process B．the cost of adaptation varies with time C．global warming affects adaptation forms D．adaptation to climate change is challenging ‎66．What is special with regard to Rezwan's project?‎ A．The project receives government support.‎ B．Different organizations work with each other.‎ C．His organization makes the best of a bad situation.‎ D．The project connects flooded roads and highways.‎ ‎67．What did the Ice Man do to reduce the effect of global warming?‎ A．Storing ice for future use.‎ B．Protecting the glaciers from melting.‎ C．Changing the irrigation time.‎ D．Postponing the melting of the glaciers.‎ ‎68．What do we learn from the Peru example?‎ A．White paint is usually safe for buildings.‎ B．The global warming trend cannot be stopped.‎ C．This country is heating up too quickly.‎ D．Sunlight reflection may relieve global warming.‎ ‎69．According to the author, polluting industries should ________．‎ A．adapt to carbon pollution B．plant highly profitable crops C．leave carbon emission alone D．fight against carbon pollution ‎70．What's the author's preferred solution to global warming?‎ A．Setting up a new standard.‎ B．Reducing carbon emission.‎ C．Adapting to climate change.‎ D．Monitoring polluting industries.‎ ‎【文章大意】 本文是一篇说明文，主要介绍了世界各地适应如今全球变暖的气候的方法。‎ ‎65. A　句意理解题。根据第二段第二句“We are therefore not talking about adapting to a new standard，but to a constantly shifting set of conditions.”可知，我们并不是在讨论适应一个新的标准，而是适应不断变化的条件。据此可以判断，这句话的意思是：适应是一个不断变化的过程。故选A项。‎ ‎66. C　细节理解题。根据第三段第三句“Mohammed Rezwan saw opportunity where others saw only disaster.”以及该段其他内容可知，Rezwan所在的组织充分利用洪水灾害为人们提供便利，故选C项。‎ ‎68. D　细节理解题。根据第五段“Increasing Earth's reflectiveness can cool the planet…By painting buildings white, cities may slow down the warming process.”以及第六段“…painting the entire mountain peak white in the hope that the added reflectiveness will restore the lifegiving ‎ ice.”可知，提高地球对光的反射能力可以缓解气候变暖，而秘鲁农民的做法恰恰印证了这一点。故选D项。‎ ‎69. D　推理判断题。根据第七段“When the polluting industries argue that we've lost the battle to control carbon pollution and have no choice but to adapt, it's a nonsense designed to make the case for business as usual.”以及最后一段“But the most sensible form of adaptation is surely to adapt our energy systems to emit less carbon pollution.”可知，一些污染企业辩解称他们无法控制碳污染，只能选择适应，这完全是胡扯，污染企业仍然要减少碳排放，与碳污染做斗争。故选D项。‎ ‎70. B　推理判断题。根据文章最后两句“But the most sensible form of adaptation is surely to adapt our energy systems to emit less carbon pollution. After all, if we adapt in that way, we may avoid the need to change in so many others.”可知，作者认为最合理的应对全球变暖的方法是减少碳排放，此举将避免在其他很多方面改变的需要。故选B项。‎ ‎【名师点睛】‎ ‎　　词义猜测技巧 ‎　　1、根据定义或上下文解释进行猜测 ‎　　有时短文中出现一个需要猜测其意义的词或短语，下面接着出现其定义或解释，这就是判断该词或短语意义的主要依据。例如：‎ ‎　　Annealing is a way of making metal softer by heating it and then letting it cool very slowly.‎ 句子给予annealing 以明确的定义，即“退火”。‎ ‎2、根据同位关系进行猜测 阅读中出现的难词有时后面紧跟一个同位语，对前面的词进行解释，这时可利用同位关系对前面或后面的词义或句意进行猜测。例如：‎ ‎　　They traveled a long way, at last got to a castle, a large building in old times.‎ ‎　　同位语部分a large building in old times 给出了castle 的确切词义，即古时候的“城堡”。‎ ‎　　We are on the night shift—from midnight to 8 a.m.— this week.‎ ‎　　两个破折号之间的短语很清楚地表明night shift 是“夜班”的意思。‎ ‎　　The “Chunnel”, a tunnel(隧道) connecting England and France, is now complete.‎ ‎　　此句中a tunnel connecting England and France是Chunnel的同位语。因此，The “Chunnel”就是英法之间的海底隧道。‎ ‎　　3、根据构词法(前缀、后缀、复合、派生等)进行猜测 ‎　　在英语中，有很多词可以在前面加前缀，在后面加后缀，从而构成一个词，乍看起来，这个词可能是新词，但掌握了一定的构词知识，就不难猜出它的词义。例如：‎ ‎　　“Our parties are aimed for children 2 to 10,” Anaclerio said, “and they’re very interactive and creative in that they built a sense of drama based on a subject.”‎ ‎　　文中interactive是由前缀inter-(相互的)和active(活动的，活跃的)而构成的，同时根据上下文的意思可以判断，该词的含义应是“互动的”。‎ ‎　　Perhaps, we can see some possibilities for next fifty years. But the next hundred?‎ ‎　　possibility 是 possible 的同根名词， 据此可以判断定 possibility 意思是“可能性”。‎ ‎　　4、根据因果关系进行猜测 ‎　　在一篇阅读文章中，根据原因可以预测结果，根据结果也可以找出原因。例如：‎ ‎　　The lack of movement caused the muscles to weaken. Sometimes the weakness was permanent. So the player could never play the sport again.‎ ‎　　从后面的结果“永远不能再运动”中，可以推测 permanent 的意思为“永远的，永久的”。‎ ‎　　5、根据上下文的指代关系进行猜测 ‎　　文章中的代词it, that, he, him 或them可以指上文提到的人或物，其中it和that还可以指一件事。有时代词指代的对象相隔较远，要认真查找;也有时需要对前面提到的内容进行总结，才能得出代词所指代的事。例如：‎ ‎　　Like Schmid, the editors of several self-published art magazines also champion (捍卫) found photographs. One of them, called simply Found, was born one snowy night in Chicago, when Davy Rothbard returned to his car to find under his wiper(雨刷) an angry note intended for someone else: “Why’s your car HERE at HER place?”‎ ‎　　them指的是前面出现的self-published art magazines。‎ ‎　　6、根据同义关系进行猜测 ‎　　当词或短语之间有并列连词and 或or时，其连接的两项内容在含义上是接近的或递进的，由此确定同等关系中的某个生词所属的义域，由此可推知其大致意思。‎ ‎　　7、根据转折或对比关系进行猜测 ‎　　根据上下句的连接词，如but, however, otherwise等就可以看到前后句在意义上的差别，从而依据某一句的含义，来确定另一句的含义。另外，分号也可以表示转折、对比或不相干的意义。例如：‎ ‎　　A child’s birthday party doesn’t have to be a hassle; it can be a basket of fun.‎ ‎　　从前后两句的意思可以看出，hassle和a basket of fun肯定是近乎相反的意义。所以不难判断hassle的意思是“困难，麻烦”。‎ 考点：环保类短文阅读 ‎ [2019·全国卷Ⅰ]‎ D A buildityourself solar still(蒸馏器) is one of the best ways to obtain drinking water in areas where the liquid is not readily available. Developed by two doctors in the US Department of Agriculture, it's an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it's all but impossible to find natural substitutes. The only components required, though, are a 5′×5′ sheet of clear or slightly milky plastic, six feet of plastic tube, and a container—perhaps just a drinking cup—to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.‎ To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher's productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up—and out—the side of the hole.‎ Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet's centre down with a rock. The plastic should now form a cone(圆锥体) with 45degreeangled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup. ‎ The solar still works by creating a greenhouse under the plastic. Ground water evaporates (蒸发) and collects on the sheet until small drops of water form, run down the material, and fall off into the cup. When the container is full, you can suck the refreshment out through the tube, and won't have to break down the still every time you need a drink. ‎ ‎32．What do we know about the solar still equipment from the first paragraph?‎ A．It's delicate. B．It's expensive.‎ C．It's complex. D．It's portable.‎ ‎33．What does the underlined phrase “the water catcher” in Paragraph 2 refer to?‎ A．The tube. B．The still.‎ C．The hole. D．The cup.‎ ‎34．What is the last step of constructing a working solar still?‎ A．Dig a hole of a certain size. ‎ B．Put the cup in place.‎ C．Weight the sheet's centre down. ‎ D．Cover the hole with the plastic sheet.‎ ‎35．When a solar still works, drops of water come into the cup from ________．‎ A．the plastic tube B．outside the hole C．the open air D．beneath the sheet ‎【文章大意】 本文是一篇科普文章。文章主要介绍了一种自己可以亲手制作的太阳能蒸馏器的方法和它的工作原理。这种蒸馏器所需的材料简单，适用于任何缺水的地方。‎ ‎33. B　词义猜测题。根据文章“Try to make the hole in a damp area to increase the water catcher's productivity.”可知，最好在潮湿的地方挖洞，以提高接水器的工作效率。接水器指的是在潮湿的地方挖洞，在洞的底部放一个杯子，杯子上方用塑料板遮挡。整个装置构成接水器，而不是某个部分。这一题很容易错选D。就算在干燥的地方挖洞，杯子也可以接水，杯子接水的事实并不会因为周围的环境变化而变化，杯子的工作效率是不变的。故选B。‎ ‎34. C　细节理解题。根据文章第三段中的“Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet's centre down with a rock.”可知，最后一步是weighting the sheet's centre down with a rock，即“放一块石头在塑料板的中间，把它压下去”，故选C。‎ ‎35. D　推理判断题。根据最后一段中的“Ground water evaporates (蒸发) and collects on the sheet until small drops of water form, run down the material, and fall off into the cup.”可知，地下水蒸发，在塑料板上聚集起来直到形成小水滴落在杯子里。塑料板是在杯子上面的，所以水滴是凝聚在塑料板的下面。故选D。‎ ‎【名师点睛】‎ 近年来全国统一高考中加大了对考生猜词义能力的考查，因此，掌握一定的猜词技巧，对突破高考阅读理解、提高同学们的英语语言能力都有非常重要的意义。这类试题包括对生词生义的推测、熟词生义的推测、以及对it/they/them等代词的确指对象的判断等。‎ 做这种类型的题，要根据词、词组、句子所在的语境来判断其意义。因此熟练掌握一些猜词技巧是做好这类题的关键。命题者在出这类题时惯用常规词义来麻痹考生，考生要特别注意熟词生义，切不可脱离语境想当然。猜测词义时，要掌握以下六种解题技巧：‎ 技巧 1 定义法：一般通过定义/定语从句/词组或同位语从句来确定词义。 ‎ 技巧 2 对比法：利用文中的反义词、表对比关系的词猜测词义。 ‎ 技巧 3 因果法：从原因推测结果，从结果推测原因。 ‎ 技巧4 例举法：利用文中的举例猜测词义。 ‎ 技巧5 构词法：在猜测词义过程中，我们还可以依靠构词法方面的知识，从生词本身猜测词义。 ‎ 技巧6 根据文段中出现的同义、近义或反义词的意思进行判断。 ‎ 技巧7 根据句子结构进行判断。 ‎ 技巧8 根据文章的背景进行判断。 ‎ 技巧9 上下文：利用语境及前后的提示来猜测词义。‎ 本篇阅读中的第33小题就属于词义猜测题。考生可以根据技巧9 上下文：利用语境及前后的提示来猜测词义来选择正确答案。划线短语the water catcher很简单，考生一看就知道是“获得水的物品”的意思，在蒸馏器整个装置中，接水的东西就是杯子，这根据常识也知道的，因此很容易错选为D选项。如果考生仔细读划线短语所在的句子Try to make the hole in a damp area to increase the water catcher’s productivity就会发现一个关键的单词productivity。productivity表示“生产效率，工作效率”，杯子接水是它本来的功能，不会因为环境变化而加快聚水或减慢聚水。在潮湿的地方挖洞是因为潮湿的土中含有的水相对丰富，水蒸气蒸发凝成水珠就快些，这和水杯完全没有关系。所以结合上下文可知，the water catcher指的是蒸馏器整个装置。 ‎ ‎ [2019·全国卷Ⅱ]‎ C Terrafugia Inc.said Monday that its new flying car has completed its first flight，bringing the company closer to its goal of selling the flying car within the next year. The vehicle—named the Transition—has two seats, four wheels and wings that fold up so it can be driven like a car. The Transition，which flew at 1，400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23gallon tank of gas and burns 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.‎ Around 100 people have already put down a $10，000 deposit to get a Transition when they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don't expect it to show up in too many driveways. It's expected to cost $279，000.And it won't help if you're stuck in traffic. The car needs a runway.‎ Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The government has already permitted the company to use special materials ‎ to make it easier for the vehicle to fly. The Transition is now going through crash tests to make sure it meets federal safety standards.‎ Mann said Terrafugia was helped by the Federal Aviation Administration's decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes. Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition，a requirement pilots would find relatively easy to meet.‎ ‎28．What is the first paragraph mainly about?‎ A．The basic data of the Transition. ‎ B．The advantages of flying cars.‎ C．The potential market for flying cars. ‎ C．The designers of the Transition.‎ ‎29．Why is the Transition unlikely to show up in too many driveways?‎ A．It causes traffic jams. ‎ B．It is difficult to operate.‎ C．It is very expensive. ‎ D．It burns too much fuel.‎ ‎30．What is the government's attitude to the development of the flying car?‎ A．Cautious.

Phil Blythe explains: “For many older people, particularly those living alone or in the country, driving is important for preserving their independence, giving them the freedom to get out and about without having to rely on others.‎ ‎“But we all have to accept that as we get older our reactions slow down and this often results in people avoiding any potentially challenging driving conditions and losing confidence in their driving skills. The result is that people stop driving before they really need to.”‎ Dr Amy Guo, the leading researcher on the older driver study, explains: “The DriveLAB is helping us to understand what the key stress points and difficulties are for older drivers and how we might use technology to address these problems.‎ ‎“For example, most of us would expect older drivers always go slower than everyone else but surprisingly, we found that in 30mph zones they struggled to keep at a constant speed and so were more likely to break the speed limit and be at risk of getting fined. We're looking at the benefits of systems which control their speed as a way of preventing that.‎ ‎“We hope that our work will help with technological solutions(解决方案) to ensure that older drivers stay safer behind the wheel.”‎ ‎32．What is the purpose of the DriveLAB?‎ A．To explore new means of transport.‎ B．To design new types of cars.‎ C．To find out older drivers' problems.‎ D．To teach people traffic rules.‎ ‎33．Why is driving important for older people according to Phil Blythe?‎ A．It keeps them independent.‎ B．It helps them save time.‎ C．It builds up their strength.‎ D．It cures their mental illnesses.‎ ‎34．What do researchers hope to do for older drivers?‎ A．Improve their driving skills.‎ B．Develop driverassist technologies.‎ C．Provide tips on repairing their cars.‎ D．Organize regular physical checkups.‎ ‎35．What is the best title for the text?‎ A．A new model electric car B．A solution to traffic problems C．Driving services for elders D．Keeping older drivers on the road ‎【文章大意】 本文是一篇说明文，主要介绍了老年人开车会面临的问题及相应的解决方法。‎ ‎32.

According to a new survey(调查) by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7 to 12yearolds said they felt tired during the day, and 15% said they had fallen asleep at school.‎ How much sleep you need depends a lot on your age. Babies need a lot of rest: Most of them sleep about 18 hours a day! Adults need about eight hours. For most schoolage children, ten hours is ideal (理想的). But the new National Sleep Foundation survey found that 35% of 10 to 12yearolds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.‎ ‎“More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone，” says Dr Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers' bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.‎ Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7：25 am to 8：30 am. Students, parents and teachers are pleased with the results.‎ ‎25．What is the new National Sleep Foundation survey on?‎ A. American kids' sleeping habits. ‎ B. Teenagers' sleeprelated diseases.‎ C. Activities to prevent sleeplessness. ‎ D. Learning problems and lack of sleep.‎ ‎26．How many hours of sleep do 11yearolds need every day?‎ A. 7 hours. B. 8 hours. ‎ C. 10 hours. D. 18 hours.‎ ‎27．Why do teenagers go to sleep late according to Carskadon?‎ A. They are affected by certain body chemicals.‎ B. They tend to do things that excite them.‎ C. They follow their parents' examples.‎ D. They don't need to go to school early.‎ ‎【文章大意】 本文是一篇说明文。作者主要介绍了当今美国青少年晚睡的坏习惯，以及产生的原因和应对措施等。‎ ‎26.

In the 1980s, electrical lines and lead poisoning(铅中毒) nearly drove them to dying out. Now, electric shock training and medical treatment are helping to rescue these big birds.‎ ‎ In the late 1980s, the last few condors were taken from the wild, and there are now more than 150 flying over California and nearby Arizona, Utah and Baja in Mexico.‎ ‎ Electrical lines have been killing them off. “As they go in to rest for the night, they just don’t see the power lines,” says Bruce Rideout of San Diego Zoo. Their wings can bridge the gap between lines, resulting in electrocution(电死) if they touch two lines at once.‎ ‎ So scientists have come up with a shocking idea. Tall poles, placed in large training areas, teach the birds to stay clear of electrical lines by giving them a painful but undeadly electric shock. Before the training was introduced, 66% of set-freed condors died of electrocution. This has now dropped to 18%.‎ ‎ Lead poisonous has proved more difficult to deal with. When condors eat dead bodies of other animals containing lead, they absorb large quantities of lead. This affects their nervous systems and ability to produce baby birds, and can lead to kidney(肾) failures and death. So condors with high levels of lead are sent to Los Angeles Zoo, where they are treated with calcium EDTA, a chemical that removes lead from the blood over several days. This work is starting to pay off.

C推理判断题。根据“just under eight years”可知，神鹰的平均寿命太短，排除A；根据“Although these measures are not effective forever”可知，目前采用的措施并不能永远有效，排除D；根据第六段“They are truly good birds that are worth every effort we put into recovering them.”可知，Rideout团队的研究兴趣在于怎样挽救这一濒危物种，故选C。‎ 考点：环保类短文阅读。 ‎ ‎【名师点睛】‎ 推理判断题属于主观题，是层次较高的题目。它包括判断题和推理题。这两类题常常相互依存，推理是为了作出正确的判断，正确的判断又依赖于合乎逻辑的推理。此类题要求在理解表面文字的基础上，作出判断和推论，从而得到文章的隐含意思和深层意思，也就是通过文章中的文字信息、上下文的逻辑关系及事物的发展变化等已知的信息，推断出作者没有直接表达的态度和观点。 推理判断题的解题方法 ： 推理判断题不仅要求考生读懂文章中的每个句子的意思还要推理它们之间的关系，结合自己的生活常识和经验，再通过逻辑推理和判断，理解文章的言外之意，从而揭示文章的深层涵义。 任何一篇文章都有其特定的写作目的，读者需要知道如何去做或按照某种方式思考问题。推理判断题的答案不可能在文章中直接找到，因此推理时我们务必要忠于原文，在文章中寻找并确定可推论的依据，即：已知部分－推论的前提，从中推测出未知部分－推理的结论，切忌妄加评论，把自己的观点当成作者的观点。‎ ‎3.【2019·天津】C ‎ When John was growing up, other kids felt sorry for him. His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood, he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier.‎ ‎ These are the findings of a 40-year study that followed the lives of 456 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. “Boys who worked in the home or community gained competence (能力) and came to feel they were worthwhile members of society,” said George Vaillant, the psychologist (心理学家) who made the discovery. “And because they felt good about themselves, others felt good about them.”‎ ‎ Vaillant’s study followed these males in great detail. Interviews were repeated at ages 25, 31 and 47. Under Vaillant, the researchers compared the men’s mental-health scores with their boyhood-activity scores with their boyhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.‎ ‎ The link between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with a wide variety of people, five times as likely to be well paid and 16 times less likely to ‎ have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out. Working----at any age----is important. Childhood activities help a child develop responsibility, independence, confidence and competence---the underpinnings (基础) of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this. Yet work isn’t everything. As Tolstoy once said, “One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one’s work.”‎ ‎46. What do we know about John?‎ A. He enjoyed his career and marriage.‎ B. He had few childhood playmates.‎ C. He received little love from his family.‎ D.

Vaillant’s words in Paragraph 2 serve as _____.‎ A. a description of personal values and social values B. an analysis of how work was related to competence C. an example for parents’ expectations of their children D. an explanation why some boys grew into happy men ‎48. Vaillant’s team obtained their findings by _____.‎ A. recording the boys’ effort in school B. evaluating the men’s mental health C. comparing different sets of scores D. measuring the men’s problem solving ability ‎49.

Each time the bowl of rice is pushed over the table edge, it falls in the ground---and, in the process, it belongs out important evidence about how physical objects interact ; bowls of rice do not flood in mid-sit, but require support to remain stable. It is likely that babies are not born knowing the basic fact of the universe; nor are they ever clearly taught it. Instead, babies may form an understanding of object support through repeated experiments and then build on this knowledge to learn even more about how objects interact. Though their ranges and tools differ, the baby’s investigation and the scientist’s experiment appear to share the same aim(to learn about the natural world ), overall approach (gathering direct evidence from the world), and logic (are my observations what I expected?).‎ Some psychologists suggest that young children learn about more than just the physical world in this way---that they investigate human psychology and the rules of language using similar means. For example, it may only be through repeated experiments, evidence gathering, and finally overturning a theory, that a baby will come to accept the idea that other people can have different views and desires from what he or she has. for example, unlike the child , Mommy actually doesn’t ‎ like Dove chocolate.‎ ‎ Viewing childhood development as a scientific investigation throws on how children learn ,but it also offers an inspiring look at science and scientists. Why do young children and scientists seem to be so much alike? Psychologists have suggested that science as an effort ---the desire to explore, explain, and understand our world---is simply something that comes from our babyhood. Perhaps evolution provided human babies with curiosity and a natural drive to explain their worlds, and adult scientists simply make use of the same drive that served them as children. The same cognitive systems that make young children feel good about feel good about figuring something out may have been adopted by adult scientists. As some psychologists put it, ”It is not that children are little scientists but that scientists are big children.”‎ ‎50.

But beyond the minimum requirements as social beings, they have little instinct (本能) to help one another. Chimps in the wild seek food for themselves. Even chimp mothers regularly decline to share food with their children. Who are able from a young age to gather their own food.‎ ‎ In the laboratory, chimps don’t naturally share food either. If a chimp is put in a cage where he can pull in one plate of food for himself or, with no great effort, a plate that also provides food for a neighbor to the next cage, he will pull at random ---he just doesn’t care whether his neighbor gets fed or not. Chimps are truly selfish.‎ Human children, on the other hand are extremely corporative. From the earliest ages, they decide to help others, to share information and to participate a achieving common goals. The psychologist Michael Tomasello has studied this cooperativeness in a series of expensive with very young children. He finds that if babies aged 18 months see an worried adult with hands full trying to open a door, almost all will immediately try to help.‎ There are several reasons to believe that the urges to help, inform and share are not taught .but naturally possessed in young children. One is that these instincts appear at a very young age before most parents have started to train children to behave socially. Another is that the ‎ helping behaviors are not improved if the children are rewarded. A third reason is that social intelligence. Develops in children before their general cognitive（认知的）skills,at least when compared with chimps..In tests conducted by Tomtasell, the children did no better than the chimps on the physical world tests, but were considerably better at understanding the social world The cure of what children’s minds have and chimps’ don’t in what Tomasello calls what. Part of this ability is that they can infer what others know or are thinking. But that, even very young children want to be part of a shared purpose. They actively seek to be part of a “we”, a group that intends to work toward a shared goal.‎ ‎58. What can we learn from the experiment with chimps?‎ ‎ A.

El Nifio sees warm water, collected over several years in the western Pacific, flow back eastwards when winds that normally blow westwards weaken, or sometimes the other way round.‎ The weather effects both good and bad, are felt in many places. Rich countries gain more from ‎ powerful Nifio, on balance, than they lose. A study found that a strong Nifio in 2019 helped American’s economy grow by 15 billion, partly because of better agricultural harvest, farmers in the Midwest gained from extra rain. The total rise in agricultural in rich countries in growth than the fall in poor ones.‎ But in Indonesia extremely dry forests are in flames. A multi-year drought (干旱）in south-east Brazil is becoming worse. Though heavy rains brought about by El Nino may relieve the drought in California, they are likely to cause surface flooding and other disasters.‎ The most recent powerful Nino, in 2019-98, killed around 21,000 people and caused damage worth $36 billion around the globe. But such Ninos come with months of warning, and so much is known about how they happen that governments can prepare. According to the Overseas Development Institute (ODI), however, just 12% of disaster-relief funding in the past two decades has gone on reducing risks in advance, rather than recovery and rebuilding afterwards. This is despite evidence that a dollar spent on risk-reduction saves at least two on reconstruction.‎ Simple improvements to infrastructure (基础设施）can reduce the spread of disease. Better sewers (下水道）make it less likely that heavy rain is followed by an outbreak of the disease of bad stomach. Stronger bridges mean villages are less likely to be left without food and medicine after floods. According to a paper in 2019 by Mr Hsiang and co-authors, civil conflict is related to El Nino’s harmful effects—and the poorer the country, the stronger the link. Though the relationship may not be causal, helping divided communities to prepare for disasters would at least reduce the risk that those disasters are followed by killing and wounding people. Since the poorest are least likely to make up for their losses from disasters linked to El Nino, reducing their losses needs to be the priority.‎ ‎61. What can we learn about El Nino in Paragraph 1?‎ A. It is named after a South American fisherman.‎ B. It takes place almost every year all over the world.‎ C. It forces fishermen to stop catching fish around Christmas.‎ D. It sees the changes of water flow direction in the ocean.‎ ‎62. What may El Ninos bring about to the countries affected?‎ A. Agricultural harvests in rich countries fall.‎ B. Droughts become more harmful than floods.‎ C. Rich countries’ gains are greater than their losses.‎ D.

Here are some examples.‎ First consider something as simple as sleep. Its position presents its own challenges. The main question is whether you want your arms inside or outside the sleeping bag. If you leave your arms out, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled （芭蕾）dancer. “I’m an inside guy,” Mike Hopkins says, who returned from a six-month tour on the International Space Station. “I like to be wrapped up.”‎ On the station, the ordinary becomes strange. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it’s just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale (呼气) has a tendency to form an invisible （隐形的）cloud around you head. You can end up with what astronauts call a carbon-dioxide headache.‎ Leroy Chiao, 54, an American retired astronaut after four flights, describes what happens even before you float out of your seat,”Your inner ear thinks you’re falling . Meanwhile your eyes are telling you you’re standing straight. That can be annoying—that’s why some people ‎ feel sick.” Within a couple days —truly terrible days for some —astronauts’ brains learn to ignore the panicky signals from the inner ear, and space sickness disappears.‎ Space travel can be so delightful but at the same time invisibly dangerous. For instance, astronauts lose bone mass. That’s why exercise is considered so vital that National Aeronautics and Space Administration (NASA) puts it right on the workday schedule. The focus on fitness is as much about science and the future as it is about keeping any individual astronauts return home, and, more importantly, how to maintain strength and fitness for the two and a half years or more that it would take to make a round-trip to Mars.‎ ‎63.What is the major challenge to astronauts when they sleep in space?‎ A. Deciding on a proper sleep position B. Choosing a comfortable sleeping bag C. Seeking a way to fall asleep quickly D. Finding a right time to go to sleep.‎ ‎64.The astronauts will suffer from a carbon-dioxide headache when _____.‎ ‎ A. the y circle around on their bikes B. they use microcomputers without a stop C. they exercise in one place for a long time D. they watch a movie while pedaling ‎65.Some astronauts feel sick on the station during the first few days because _____.‎ A. their senses stop working B. they have to stand up straight C. they float out of their seats unexpectedly D. whether they are able to go back to the station ‎66.One of the NASA’s major concerns about astronauts is _____.‎ A. how much exercise they do on the station B. how they can remain healthy for long in space C. whether they can recover after returning home D. whether they are able to go back to the station ‎【解析】‎ 试题分析：‎ 这是一篇说明文。本文通过举例说明了太空生活的奇妙：在太空睡觉时，对宇航员来说主要的挑战在于恰当的睡眠姿势；宇航员在一个地方运动久了会出现碳毒性头痛；宇航员的大脑接收到矛盾的信息时会感到恶心。最后告诉我们美国国家宇航局对宇航员主要的担心是宇航员回家后的修养期和如何在太空长久地保持健康。‎ ‎63.A细节理解题。根据第二段第一、二句“First consider something as simple as sleep.

These animals typically live between the surface of the ocean and a depth of about 3,300 feet—as far as most light can reach. Most of them are extremely delicate and can be damaged by a simple touch. Sonke Johnsen, a scientist in biology, says, “These animals live through their life alone. They never touch anything unless they’re eating it, or unless something is eating them.”‎ ‎ And they are as clear as glass. How does an animal become see-through? It’s trickier than you might think.‎ ‎ The objects around you are visible because they interact with light. Light typically travels in a straight line. But some materials slow and scatter(散射) light, bouncing it away from its original path. Others absorb light, stopping it dead in its tracks. Both scattering and absorption make an object look different from other objects around it, so you can see it easily.‎ ‎ But a transparent object doesn’t absorb or scatter light, at least not very much, Light can pass through it without bending or stopping. That means a transparent object doesn’t look very different from the surrounding air or water. You don’t see it ----you see the things behind it.‎ ‎ To become transparent, an animal needs to keep its body from absorbing or scattering light. Living materials can stop light because they contain pigments(色素) that absorb specific colors of light. But a transparent animal doesn’t have pigments, so its tissues won’t absorb light. According to Johnsen, avoiding absorption is actually easy. The real challenge is preventing light from scattering.‎ Animals are built of many different materials----skin, fat, and more----and light moves through each at a different speed. Every time light moves into a material with a new speed, it bends and scatters. Transparent animals use different tricks to fight scattering. Some animals are simply very small or extremely flat. Without much tissue to scatter light, it is easier to be see—through. Others build a large, clear mass of non-living jelly-lie(果冻状的)material and spread themselves over it .‎ ‎ Larger transparent animals have the biggest challenge, because they have to make all the different tissues in their bodies slow down light exactly as much as water does. They need to look uniform. But how they’re doing it is still unknown. One thing is clear for these larger animals, staying transparent is an active process. When they die, they turn a non-transparent milky white.‎ ‎63. According to Paragraph 1, transparent animals_______.‎ ‎ A. stay in groups B. can be easily damaged ‎ C. appear only in deep ocean D. are beautiful creatures ‎64. The underlined word “dead” in Paragraph 3 means__________.‎ ‎ A. silently B. gradually ‎ C. regularly D. completely ‎65. One way for an animal to become transparent is to ________.‎ ‎ A. change the direction of light travel ‎ ‎ B. gather materials to scatter light.‎ ‎ C. avoid the absorption of light ‎ D. grow bigger to stop light.‎ ‎66. The last paragraph tells us that larger transparent animals________.‎ ‎ A. move more slowly in deep water ‎ B. stay see-through even after death ‎ C. produce more tissues for their survival ‎ D. take effective action to reduce light spreading ‎【解析】‎ 试题分析：文章解释了生活在海洋的透明生物的特点，透明原理，以及形成机制。‎ ‎63.B 细节理解题。文章第一段第三行：Mostof them are extremely delicate and can be damaged by a simple touch。得知B选项：透明动物是很容易受伤的。故选B。‎ ‎64.D 词义猜测题。该词出现在文章第三段第三行。前文提到了：你能看到的物体一种是对光线进行了散射；而另外一种是对光线的吸收。既然吸收了，那在光的传播过程中就完全阻止了，因此这里dead是完全的意思。故选D。‎ ‎65.C 推理判断题。根据第五段第一句To become transparent, an animal needs to keep its body from absorbing or scattering light。可知，想变透明就要避免散射或吸收光线，因此其中的一个方法是C选项，避免光线的吸收。故选C。‎ ‎66.D 推理判断题。根据最后一段第一句中的make all the different tissues in their bodies slow down light exactly as much as water does可以推断出D为正确答案。其中slowdown对应reduce。故选D。 ‎ ‎【考点定位】科技类说明文 ‎【名师点睛】做科技类说明文时，考生应能：理解语篇主旨要义，理解文中具体信息，根据上下文提供的线索推测生词的词义，根据文中事实和线索作出简单的判断和推理。此次出现了新型科技类说明文。往年科技类说明文的阅读难点在于专业类词汇，但是今年的“新型耳机”在问题设置上难度不大，属于文章难但题目不难的题目。所以要理解好文章做好此题就不是难题。‎ ‎3.【2019·江苏】B In the United States alone, over 100 million cell-phones are thrown away each year. Cell-phones ‎ are part of a growing mountain of electronic waste like computers and personal digital assistants. The electronic waste stream is increasing three times faster than traditional garbage as a whole.‎ Electronic devices contain valuable metals such as gold and silver. A Swiss study reported that while the weight of electronic goods represented by precious metals was relatively small in comparison to total waste, the concentration (含量) of gold and other precious metals was higher in So-called e-waste than in naturally occurring minerals.‎ Electronic wastes also contain many poisonous metals. Even when the machines are recycled and the harmful metals removed, the recycling process often is carried out in poor countries, in practically uncontrolled ways which allow many poisonous substances to escape into the environment.‎ Creating products out of raw materials creates much more waste material, up to 100 times more, than the material contained in the finished products. Consider again the cell-phone, and imagine the mines that produced those metals, the factories needed to make the box and packaging(包装) it came in. Many wastes produced in the producing process are harmful as well.‎ The U.S. Environmental Protection Agency notes that most waste is dangerous in that “the production, distribution, and use of products — as well as management of the resulting waste — all result in greenhouse gas release.” Individuals can reduce their contribution by creating less waste at the start — for instance, buying reusable products and recycling.‎ In many countries the concept of extended producer responsibility is being considered or has been put in place as an incentive (动机) for reducing waste. If producers are required to take back packaging they use to sell their products, would they reduce the packaging in the first place?‎ Governments’ incentive to require producers to take responsibility for the packaging they produce is usually based on money. Why, they ask, should cities or towns be responsible for paying to deal with the bubble wrap (气泡垫) that encased your television?‎ From the governments’ point of view, a primary goal of laws requiring extended producer responsibility is to transfer both the costs and the physical responsibility of waste management from the government and tax-payers back to the producers.‎ ‎58.By mentioning the Swiss study, the author intends to tell us that _________ .‎ A. the weight of e-goods is rather small B. E-waste deserves to be made good use of C. natural minerals contain more precious metals D. the percentage of precious metals is heavy in e-waste ‎59.The responsibility of e-waste treatment should be extended _________ .‎ A. from producers to governments ‎ B. from governments to producers C. from individuals to distributors ‎ D. from distributors to governments ‎60.

It’s very likely that you’ll want to have volunteers to help with the organization’s activities. To do so, it should help to understand why people undertake volunteer work and what keeps their interest in the work.‎ Let’s begin with the question of why people volunteer. Researchers have identified several factors that motivate people to get involved. For example, people volunteer to express personal values related to unselfishness, to expand their range of experiences, and to strengthen social relationships. If volunteer positions do not meet these needs, people may not wish to participate. To select volunteers, you may need to understand the motivations of the people you wish to attract.‎ People also volunteer because they are required to do so. To increase levels of community service, some schools have launched compulsory volunteer programs. Unfortunately, these programs can shift people’s wish of participation from an internal factor (e.g., “I volunteer because it’s important to me”) to an external factor (e.g., “I volunteer because I’m required to do so”). When that happens, people become less likely to volunteer in the future. People must be sensitive to this possibility when they make volunteer activities a must.‎ Once people begin to volunteer, what leads them to remain in their positions over time? To answer this question, researchers have conducted follow-up studies in which they track volunteers over time. For instance, one study followed 238 volunteers in Florida over a year. One of the most important factors that influenced their satisfaction as volunteers was the amount of suffering they experienced in their volunteer positions. Although this result may not surprise you, it leads to important practical advice. The researchers note that attention should be given to “training methods that would prepare volunteers for troublesome situations or provide them with strategies for coping with the problem they do experience”.‎ Another study of 302 volunteers at hospitals in Chicago focused on individual differences in the degree to which people view “volunteer” as an important social role. It was assumed that those people for whom the role of volunteer was most part of their personal identity would also be most likely to continue volunteer work. Participants indicated the degree to which the social role mattered by responding to statements such as “Volunteering in Hospital is an important part of who I am.” Consistent with the researchers’ expectations, they found a positive correlation (正相关) between the strength of role identity and the length of time people continued to volunteer. These results, once again, lead to concrete advice: “Once an individual begins ‎ volunteering, continued efforts might focus on developing a volunteer role identity.... Items like T-shirts that allow volunteers to be recognized publicly for their contributions can help strengthen role identity”.‎ ‎61.People volunteer mainly out of ______ .‎ A. academic requirements B. social expectations C. financial rewards D. internal needs ‎62.What can we learn from the Florida study?‎ A. Follow-up studies should last for one year. B. Volunteers should get mentally prepared.‎ C. Strategy training is a must in research. D.

We tend to blame TV, he says, for problems it doesn’t really cause, overlooking our own roles in shaping children’s minds.‎ One traditional belief about television is that it reduces a child’s ability to think and to understand the world. While watching TV, children do not merely absorb words and images (影像). Instead, they learn both explicit and hidden meanings from what they see. Actually, children learn early the psychology of characters in TV shows. Furthermore, as many teachers agree, children understand far more when parents watch TV with them, explaining new words and ideas. Yet, most parents use an educational program as a chance to park their kids in front of the set and do something in another room.‎ Another argument against television is that it replaces reading as a form of entertainment. But according to Anderson, the amount of time spent watching television is not related to reading ability. TV doesn’t take the place of reading for most children; it takes the place of similar sorts of recreation, such as listening to the radio and playing sports. Things like parents’ educational background have a stronger influence on a child’s reading. “A child’s reading ability is best predicted by how much a parent reads.” Anderson says.‎ Traditional wisdom also has it that heavy television-watching lowers IQ (智商) scores and affects school performance. But here, too, Anderson notes that no studies have proved it. In fact, research suggests that it’s the other way around. “If you’re smart young, you’ll watch less ‎ TV when you’re older,” Anderson says. Yet, people of lower IQ tend to be lifelong television viewers.‎ For years researchers have attempted to show that television is dangerous to children. However, by showing that television promotes none of the dangerous effects as conventionally believed, Anderson suggests that television cannot be condemned without considering other influences.‎ ‎36. By watching TV, children learn _________.‎ A. images through words B. more than explicit meanings C. more about images than words D. little about people’s psychology ‎37. An educational program is best watched by a child _________.‎ A. on his own B. with other kids C. with his parents D. with his teachers ‎38. Which of the following is most related to children’s reading ability?‎ A. Radio-listening B. Television-watching C. Parents’ reading list D. Parents’ educational background ‎39. Anderson believed that _________.‎ A. the more a child watches TV, the smarter he is B. the younger a child is, the more he watches TV C. the smarter a child is, the less likely he gets addicted to TV D. the less a child watches TV, the better he performs at school ‎40. What is the main purpose of the passage?‎ A. To advise on the educational use of TV.‎ B. To describe TV’s harmful effects on children.‎ C. To explain traditional views on TV influences.‎ D. To present Anderson’s unconventional ideas.‎ ‎【解析】‎ ‎36. B细节理解题。根据第二段的Instead, they learn both explicit and hidden meanings from what they see.可知孩子们通过看电视，可以学到显性和隐藏的意义，因此不仅仅学到隐藏的意思。故选B。‎ ‎37.

The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of, certain animals and birds, and even disturbs the world’s ecological balance.‎ On a local level, the damage of the forest required by full-sun fields affects the area’s birds and animals. The shade of the forest trees provides a home for birds and other special(物种) that depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many special are quickly dying out.‎ On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens(威胁)human life. Medical research often makes use of the forests' plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world's groundwater.‎ Both locally and globally, the continued spread of full-sun coffee plantations (种植园)could ‎ mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world's climate, and studies show that loss of oxygen-giving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic(酸性的) soil conditions.‎ It is obvious that the way much coffee is grown affects many aspects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.‎ ‎54. What can we learn about full-sun coffee production from Paragraph 4?‎ A. It limits the spread of new growing techniques.‎ B. It leads to air pollution and global warming.‎ C. It slows down the loss of shade trees.‎ D. It improves local soil conditions.‎ ‎55. The purpose of the text is to .‎ A. entertain B. advertise C. instruct D. persuade ‎56. Where does this text probably come from ?‎ A. An agricultural magazine.‎ B. A medical journal.‎ C.

But robins are in danger of wearing themselves out by singing too much. Robins are singing all night一as well as during the day, British-based researchers say.‎ ‎ David Dominoni, of Glasgow University, said that light from street lamps, takeaway signs and homes is affecting the birds' biological clocks, leading to them being wide awake when they should be asleep.‎ ‎ Dr Dominoni, who is putting cameras inside nesting boxes to track sleeping patterns, said lack of sleep could put the birds’ health at risk. His study shows that when robins are exposed to light at night in the lab, it leads to some genes being active at the wrong time of day. And the more birds are exposed to light, the more active they are at night.‎ He told people at a conference, "There have been a couple of studies suggesting they are increasing their song output at night and during the day they are still singing. Singing is a costly behaviour and it takes energy. So by increasing their song output, there might be some costs of energy."‎ And it is not just robins that are being kept awake by artificial light. Blackbirds and seagulls are also being more nocturnal. Dr Dominoni said, "In Glasgow where I live, gulls are a serious problem. I have people coming to me saying `You are the bird expert. Can you help us kill these gulls?'.During the breeding(繁殖)season, between April and June, they are very active at night and very noisy and people can't sleep."‎ Although Dr Dominoni has only studied light pollution, other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud noise.‎ However, some birds thrive(兴旺)in noisy environments. A study from California Polytechnic University found more hummingbirds in areas with heavy industrial machinery. It is thought that they are capitalising on their predators(天敌)fleeing to quieter areas.‎ ‎42.According to Dr Dominoni's study, what cause robins to sing so much?‎ ‎ A. The breeding season. B. The light in modern life ‎ C. The dangerous environment. D. The noise from heavy machinery.‎ ‎43.What is the researchers' concern over the increase of birds' song output?‎ ‎ A. The environment might be polluted.‎ ‎ B. The birds' health might be damaged.‎ ‎ C. The industry cost might be increased.‎ ‎ D. The people's hearing might be affected.‎ ‎44.What does the underlined word "nocturnal" in Paragraph 5 mean?‎ ‎ A. Active at night. B. Inactive at night.‎ ‎ C. Active during the day. D. Inactive during the day.‎ ‎45.Why do some birds thrive in noisy environments?‎ ‎ A. Because there are fewer dangers.‎ ‎ B. Because there is more food to eat.‎ C.

But a new study suggests they used a little rock‘n’roll. Long-ago builders could have attached wooden pole s to the stones and rolled then across the sand, the scientists say.‎ ‎“Technically, I think what they’re proposing is possible,” physicist Daniel Bonn said.‎ People have long puzzled over how the Egyptians moved such huge rocks. And there’s no obvious answer. On average, each of the two million big stones weighed about as much as a large pickup truck. The Egyptians somehow moved the stone blocks to the pyramid site from about one kilometer away.‎ The most popular view is that Egyptian workers slid the blocks along smooth paths. Many scientists suspect workers first would have put the blocks on sleds(滑板). Then they would have dragged them along paths. To make the work easier, workers may have lubricated the paths either with wet clay or with the fat from cattle. Bonn has now tested this idea by building small sleds and dragging heavy objects over sand.‎ Evidence from the sand supports this idea. Researchers found small amounts of fat, as well as a large amount of stone and the remains of paths.‎ However, physicist Joseph West thinks there might have been a simpler way , who led the new study . West said , “I was inspired while watching a television program showing how sleds might have helped with pyramid construction . I thought , ‘Why don’t they just try rolling the things?’ “A square could be turned into a rough sort of wheel by attaching wooden poles to its sides , he realized . That , he notes , should make a block of stone” a lot easier to roll than a square”.‎ So he tried it.‎ He and his students tied some poles to each of four sides of a 30-kilogram stone block. That action turned the block into somewhat a wheel. Then they placed the block on the ground.‎ They wrapped one end of a rope around the block and pulled. The researchers found they could easily roll the block along different kinds of paths. They calculated that rolling the block required about as much force as moving it along a slippery(滑的)path.‎ West hasn’t tested his idea on larger blocks, but he thinks rolling has clear advantages ‎ over sliding. At least, workers wouldn’t have needed to carry cattle fat or water to smooth the paths.‎ ‎46.It’s widely believed that the stone blocks were moved to the pyramid site by ______.‎ A. rolling them on roads B. pushing them over the sand C. sliding them on smooth paths D. dragging them on some poles ‎47.The underlined part “lubricated the paths” in Paragraph 4 means____.‎ A. made the path wet B. made the path hard C. made the path wide D. made the path slippery ‎48.What does the underlined word “it”in Paragraph 7 refer to?‎ A. Rolling the blocks with poles attached.‎ B. Rolling the blocks on wooden wheels.‎ C. Rolling poles to move the blocks.‎ D. Rolling the blocks with fat.‎ ‎49.Why is rolling better than sliding according to West ?‎ ‎ A. Because more force is needed for sliding.‎ ‎ B. Because rolling work can be done by fewer cattle.‎ ‎ C. Because sliding on smooth road is more dangerous.‎ ‎ D. Because less preparation on path is needed for rolling.‎ ‎50.What is the text mainly about ?‎ ‎ A. An experiment on ways of moving blocks to the pyramid site.‎ ‎ B. An application of the method of moving blocks to the pyramid site.‎ ‎ C.

Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo. ‎ While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.‎ The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn’t just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.‎ Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.‎ Fellow Robots is one company bringing social robots to the market. The company’s “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product’s location in the store. It can also speak different languages and ‎ make recommendations for different items based on what the customer is shopping for.‎ The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “We have technologies to train social robots to do things not for us, but with us,” said Breazeal.‎ ‎41. How are social robots different from household robots?‎ ‎ A. They can control their emotions. B. They are more like humans.‎ C. They do the normal housework. D. They respond to users more slowly.‎ ‎42. What can a Jibo robot do according to Paragraph 3?‎ A. Communicate with you and perform operations.‎ B. Answer your questions and make requests.‎ C. Take your family pictures and deliver milk.‎ D. Obey your orders and remind you to take pills.‎ ‎43. What can Oshbot work as?‎ A. A language teacher. B. A tour guide.‎ C. A shop assistant. D.

Instead，we are diurnal creatures, with eyes adapted to living in the sun’s light. This is a basic evolutionary fact, even though most of us don’t think of ourselves as diurnal beings. Yet it’s the only way to explain what we’ve done to the night: We’ve engineered it to receive us by filling it with light. ‎ The benefits of this kind of engineering come with consequences 一 called light pollution 一 whose effects scientists are only now beginning to study. Light pollution is largely the result of bad lighting design，which allows artificial light to shine outward and upward into the sky. III-designed lighting washes out the darkness of night and completely changes the light levels 一 and light rhythms — to which many forms of life, including, ourselves, have adapted. Wherever human light spills into the natural world, some aspect or life is affected . ‎ In most cities the sky looks as though it has been emptied of stars, leaving behind a vacant haze(霾) that mirrors our fear of the dark. We’ve grown so used to this orange haze that the original glory of an unlit nigh, - dark enough for the planet Venus to throw shadow on Earth, is wholly beyond our experience, beyond memory almost.‎ We’ve lit up the night as if it were an unoccupied country, when nothing could be further form the truth. Among mammals alone, the number of nocturnal species is astonishing, Light is ‎ a powerful biological force, and on many species it acts as a magnet(磁铁). The effect is so powerful that scientists speak of songbirds and seabirds being “captured” by searchlights on land or by the light from gas flares on marine oil platforms. Migrating at night, birds tend to collide with brightly lit tall buildings.‎ Frogs living near brightly lit highways suffer nocturnal light levels that are as much as a million times righter than normal, throwing nearly every aspect of their behavior out of joint including most other creatures ,we do need darkness .Darkness is as essential to our biological welfare, to our internal clockwork, as light itself.‎ Living in a glare of our making,we have cut ourselves off from our evolutionary and cultural heritage—the light of the stars and the rhythms of day and night .In a very real sense light pollution causes us to lose sight of our true place in the universe, to forget the scale of our being, which is best measured against the dimensions of a deep night with the Milky Way—the edge of our galaxy arching overhead.‎ ‎50. According to the passage, human being .‎ A. prefer to live in the darkness B. are used to living in the day light ‎ C. were curious about the midnight world ‎ D. had to stay at home with the light of the moon ‎51. What does “it”(Paragraph 1) most probably refer to?‎ A. The night. B. The moon C. The sky D. The planet ‎52. The writer mentions birds and frogs to .‎ A. provide examples of animal protection B. show how light pollution affects animals ‎ C. compare the living habits of both species ‎ D. explain why the number of certain species has declined ‎ ‎53. It is implied in the last paragraph that . ‎ A. light pollution dose harm to the eyesight of animals B. light pollution has destroyed some of the world heritages C. human beings cannot go to the outer space ‎ D. human beings should reflect on their position in the universe ‎54. What might be the best title for the passage?‎ A. The Magic light. B. The Orange Haze.‎ C. The Disappearing Night. D. The Rhythms of Nature.‎ ‎【解析】‎ 试题分析：文章介绍了光污染对于动物和人类的影响，呼吁我们反思我们的行为。‎ ‎52. B 写作目的题 根据第二段第一句话” The benefits of this kind of engineering come with consequences 这项工程带来好处的同时也带来了坏处“和最后一句，“Wherever human light spills into the natural world, some aspect of life is affected“, 此句意为无论光洒在什么地方，生活都会受到一些影响。 所以答案是show how light pollution affects animals说明光污染影响的动物 ‎53. D 推理题，最后一段的意思是” Living in a glare of our making ,we have cut ourselves off from our evolutionary and cultural heritage—the light of the stars and the rhythms of day and night .In a very real sense light pollution causes us to lose sight of our true place in the universe, to forget the scale of our being, which is best measured against the dimensions of a deep night with the Milky Way—the edge of our galaxy arching overhead.生活在一个刺眼世界，我们已经远离了进化和文化遗产：星星和昼夜节律的光。在一个非常真实的意义上，光污染使我们在宇宙中失去真我，而这些失去的正好就是最好的测量银河系银河深夜的工具。“ 根据语意，不难得出答案是D. human beings should reflect on their position in the universe人类应该反思自己的行为。但此题易错选B，之所以不选B是因为some of 的表达是扩大了说法，以偏概全。‎ ‎54. C 标题题，根据，文章出现最多的就是light和night, 我们可以知道答案是C。之所以不选A，是因为它所使用的形容词Magic意思是奇幻的，这个单词具有褒义的意思。而C选项的disappearing 是消失的，这符合本文的语境，让我们反思。 ‎ ‎【考点定位】这是一篇夹叙夹议的文章 ‎【名师点睛】对于这种文章，一定要读懂作者的观点是什么？留意作者看法的用词，即是文章所使用的形容词是支持还是反对。尤其要读懂第一段的内容，因为往往开头是陈述作者观点的地方。如第一段“If humans were truly at home under the light of the moon and stars，we would go in darkness happily，the midnight world as visible to us as it is to the vast number of nocturnal(夜间活动的) species on this planet. Instead，we are diurnal creatures, with eyes adapted to living in the sun’s light.如果人类真的在家里的月亮和星星的光下，我们会在黑暗中快乐，午夜的世界，我们可见的是夜间的大量在这个星球上的物种。相反，我们是日行动物，眼睛适应了太阳的光线。”‎ ‎11.【2019·安徽】C ‎ As Internet users become more dependent on the Internet to store information, are people remember less? If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.‎ ‎ In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.‎ ‎ In another experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet. The information was in a specific computer folder (文件夹). Surprisingly, people later remember the folder location (位置) better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called "transactive memory (交互记忆)".‎ ‎ According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn't mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.‎ ‎64. The passage begins with two questions to ______. ‎ ‎ A. introduce the main topic B. show the author's altitude C. describe how to use the Interne. D. explain how to store information ‎65. What can we learn about the first experiment?‎ A. Sparrow's team typed the information into a computer. ‎ B. The two groups remembered the information equally well.‎ C. The first group did not try to remember the formation. ‎ D. The second group did not understand the information.‎ ‎66. In transactive memory, people ______.‎ A. keep the information in mind B. change the quantity of information ‎ C. organize information like a computer D. remember how to find the information ‎67. What is the effect of the Internet according to Sparrow's research? ‎ A. We are using memory differently. B. We are becoming more intelligent.‎ C. We have poorer memories than before. D. We need a better way to access information.‎ ‎【答案】‎ ‎64. A ‎65. C ‎66. D ‎67. A ‎【解析】‎ 试题分析：文章主要讲的是互联网给人类的记忆带来的影响。互联网使用者越来越依赖互联网储存信息，人们这样做是否会丧失记忆事物的能力呢？专家怀疑互联网可能正在改变人们的记忆内容和记忆的方式。‎ ‎64.

An old joke that was popular at the time went something like this: A man is stuck up to his waist in a muddy Chicago street. Asked if he needs help, he replies, "No, thanks. I've got a good horse under me."‎ The city planner decided to build an underground drainage (排水) system, but there simply ‎ wasn't enough difference between the height of the ground level and the water level. The only two options were to lower the Chicago River or raise the city.‎ An engineer named Ellis Chesbrough convinced me the city that it had no choice but to build the pipes above ground and then cover them with dirt. This raised the level of the city's streets by as much as 12 feet.‎ This of course created a new problem: dirt practically buried the first floors of every building in Chicago. Building owners were faced with a choice: either change the first floors of their buildings into basements, and the second stories into main floors, or hoist the entire buildings to meet the new street level. Small wood-frame buildings could be lifted fairly easily. But what about large, heavy structures like Tremont Hotel, which was a six-story brick building?‎ That's where George Pullman came in. He had developed some house-moving skills successfully. To lift a big structure like the Tremont Hotel, Pullman would place thousands of jackscrews (螺旋千斤顶) beneath the building's foundation. One man was assigned to operate each section of roughly 10 jackscrews. At Pullman's signal each man turned his jackscrew the same amount at the same time, thereby raising the building slowly and evenly. Astonishingly, the Tremont Hotel stay open during the entire operation, and many of its guests didn't even notice anything was happening. Some people like to say that every problem has a solution. But in Chicago's early history, every engineering solution seemed to create a new problem. Now that Chicago's waste water was draining efficiently into the Chicago River, the city's next step was to clean the polluted river.‎ ‎61.The author mentions the joke to show ______.‎ ‎ A. horses were fairly useful in Chicago ‎ B. Chicago's streets were extremely muddy ‎ C. Chicago was very dangerous in the spring ‎ D. the Chicago people were particularly humorous ‎62.The city planners were convinced by Ellis Chesbrough to_______.‎ ‎ A. get rid of the street dirt ‎ ‎ B. lower the Chicago River ‎ C. fight against heavy floods ‎ D. build the pipes above ground ‎63.The underlined word "hoist" in Paragraph 4 means "_______".‎ ‎ A. change B. lift ‎ C. repair D. decorate ‎64.What can we conclude about the moving operation of the Tremont Hotel?‎ ‎ A. It went on smoothly as intended.‎ ‎ B. It interrupted the business of the hotel.‎ ‎ C. It involved Pullman turning ten jackscrews.‎ ‎ D. It separated the building from its foundation.‎ ‎65.The passage is mainly about the early Chicago's ______.‎ ‎ A. popular life styles and their influences ‎ B. environmental disasters and their causes ‎ C. engineering problems and their solutions ‎ D. successful businessmen and their achievements ‎【答案】 ‎ ‎61．B ‎62．D ‎63．B ‎64．A ‎65．C ‎【解析】‎ 试题分析：本文讲述了芝加哥城的问题和改造方案 ‎61．B;细节推理题。根据文章的第一段第一句话：In early history, Chicago had floors frequently, especially in the spring, making the streets so muddy that people, horses, and carts got stuck.可知芝加哥因为洪水的经常泛滥导致大街上总是泥泞不堪，行人，马和车全部都堵在路上。所以作者提及那个玩笑是为了突出芝加哥这一特点，故选B ‎62．D;细节理解题。根据第三段第一句话：An engineer named Eill Chesbrough convinced the city that it had no choice but to build the pipes above ground and then cover thenwith dirt.可知以Eill Chesbrough为首的人们认为应该在地上埋下排水管道，故选D ‎63．B;细节推理题。根据后文：Small wood-frame building could be lifted fairly easily.可知另一种方法就是将建筑升高。故选B ‎【考点定位】科普类短文阅读。 ‎ ‎【名师点睛】这是一篇科普类的文章，主要是考查上下文理解和对文章细节的把握，明白作者的构思在文章中给出的自己想法和观点以及对文章的总结。例如最后一段：Some people like to say that every problem has a solution.

Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. you can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.‎ Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious(难为情) when they’re in poorly lit places – and so more likely to eat lots of food. If your home doesn’t have enough window light, get more lamps and flood the place with brightness.‎ Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us less hungry. So when it’s time to repaint, go blue.‎ Don’t forget the clock – or the radio. People who eat slowly tend to consume about 70 fewer calories(卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at 30 minutes. And while you’re at it, actually sit down to eat. If you need some help slowing down, turning on relaxing music. It makes you less likely to rush through a meal.‎ Downsize the dishes. Big serving bowls and plants can easily makes us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one, total intake(摄入) jumps by 14 percent. And we’ll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.‎ ‎25. The text is especially helpful for those who care about ____.‎ A. their home comforts A. their body shape B. house buying C. healthy diets ‎26.

This evening, as on every Thursday night, psychologist Maud Lehanne is leading two of France’s favorite pastimes, coffee drinking and the “talking cure”. Here they are learning to get in touch with their true feelings. It isn’t always easy. They customers - some thirty Parisians who pay just under $2 (plus drinks) per session - care quick to intellectualize (高谈阔论)，slow to open up and connect. “You are forbidden to say ‘one feels,’ or ‘people think’,” Lehane told them. “Say ‘I think,’ ‘Think me’.”‎ A café society where no intellectualizing is allowed? It couldn’t seem more un-French. But Lehanne’s psychology café is about more than knowing oneself: It’s trying to help the city’s troubled neighborhood cafes. Over the years, Parisian cafes have fallen victim to changes in the French lifestyle - longer working hours, a fast food boom and a younger generation’s desire to spend more time at home. Dozens of new theme cafes appear to change the situation. Cafes focused around psychology, history, and engineering are catching on, filling tables well into the evening.‎ ‎ The city’s psychology cafes, which offer great comfort, are among the most popular places. Middle-aged homemakers, retirees, and the unemployed come to such cafes to talk about love, anger, and dreams with a psychologist. And they come to Lehanne’s group just to learn to say what they ‎ feel. “There’s a strong need in Paris for communication,” says Maurice Frisch, a cafe La Chope regular who works as a religious instructor in a nearby church. “People have few real friends. And they need to open up.” Lehanne says she’d like to see psychology cafes all over France. “If people had normal lives, these cafes wouldn’t exist”, she says, “If life weren’t a battle, people wouldn’t need a special place just to speak.” But them, it wouldn’t be France.‎ ‎32. What are people encouraged to do at the cafe La Chope?‎ A. Learn a new subject B. Keep in touch with friends.‎ C. Show off their knowledge.‎ D. Express their true feelings.‎ ‎33. How are cafes affected by French lifestyle changes?‎ A. They are less frequently visited.‎ B. They stay open for longer hours.‎ C. They have bigger night crowds.‎ D. They start to serve fast food.‎ ‎34. What are theme cafes expected to do?‎ A. Create more jobs.‎ B. Supply better drinks.‎ C. Save the cafe business.‎ D. Serve the neighborhood.‎ ‎35. Why are psychology cafes becoming popular in Paris?‎ A. They bring people true friendship.‎ B. They give people spiritual support.‎ C. They help people realize their dreams.‎ D.
