高考英语阅读训练——科普环保类 (一) It is 7 am and the alarm is going off. You know you have to be out of bed to catch the bus. But the urge to bury yourself in the bed is ever so strong. Sounds familiar? Why is it that teens find it difficult to get themselves out of bed in time every morning or stay sharp and focused during the first couple of hours of school? During adolescence, the body goes through many changes and these include a shift in sleep patterns. Researchers from MIT have been tracking the body’s need for sleep in teenagers. They found that though adolescents need as much as 9.5 hours of sleep a day, they get to bed later and later with each passing year. In fact, the sleep cycle shifts later by as much as 12 to 18 minutes each year between the ages of 10 and 20! So by the time a 10yearold who sleeps at 8 pm grows to be 17 or 18, his body naturally wants to stay up till 10:30 pm or 11 pm. According to researchers, this is because of a hormone called melatonin (褪黑激素) that is secreted (分泌) by the pineal gland — a tiny structure deep inside the brain. Melatonin regulates the body’s natural daynight rhythms. It causes a person to become sleepy by lowering his body’s core temperature. In teens, melatonin is secreted much later in the evening and continues to increase throughout the night. This makes it difficult for teens to fall asleep earlier as they did in their younger years. Likewise, the effect of melatonin continues until much later in the morning, making it hard for them to wake up early. A study found that at least one in four teens is tired and falls asleep in school at least once a week. During sleep, important body functions and brain activities happen. So how can teenagers get their sleep enough? The American Academy of Pediatrics (AAP) recommends that middle and high schools should start later — not before 8:30 am. This should give teens some more time to sleep at night. 1. From Paragraph 2, we can learn that if you sleep late, the next day you should ________. A. stay sharp B. skip breakfast C. get up late D. stay up late 2. What does the underlined word “this” in Paragraph 3 refer to? A. The students want to stay up. B. The shifts of the sleep cycle. C. The pineal gland secretes melatonin. D. The adolescents sleep late. 3. The teens go to sleep later than before because ________. A. melatonin is secreted much later B. melatonin regulates the sleep time C. they sleep a lot in the daytime D. they need to finish their homework 4. According to AAP’s recommendation, middle and high schools should ________. A. let teens sleep in the day B. let the students be active C. delay the start time D. start later at 8 am (二) It has been around for centuries, but up until very recently, traditional Chinese medicine (TCM) wasn’t fully accepted abroad. Proof of this can be found in The Treatment (《刮痧》), a 2019 film that tells the story of a Chinese man in the US who’s accused of abuse after he uses guasha, a form of TCM treatment, to cure his grandson’s disease. During the last 10 years or so, however, TCM has been getting increasingly popular all over the world. A report released by the State Council Information Office on Dec. 6 says this style of health care, which includes different forms like herbal medicine and exercise, has spread to 183 countries and regions. “We have set up 10 TCM centers outside China, and all of them are popular among locals,” Wang Guoqiang, head of the State Administration of Traditional Chinese Medicine, said at a news conference on Dec 6. “Governments of 86 countries and regions have signed agreements with the Chinese government on TCM corporation.” One of the reasons behind the growing popularity of TCM is the increase of scientific research into it. And after Tu Youyou-the Chinese scientist who discovered the anti-malaria (抗疟疾) drug qinghaosu (青蒿素)-won the Nobel Prize last year, TCM became even more famous internationally. However, all these achievements in TCM don’t mean that it’s problem-free. Over the years, TCM has faced challenges in being able to prove that it has certain effects. Some researchers have suggested TCM should be more exact and work together with Western medicine. “Bringing together with Western medicine and TCM, rather than being in competition, is where the potential for great effects is,” said Bernhard Schwartlander, the China representative of the World Health Organization. 1. The film The Treatment is mentioned in the first paragraph is to . A. introduce the film to readers B. show TCM is increasingly popular C. arouse readers’ interest in Western medicine D. prove that TCM is not fully accepted in western countries 2. We can learn from the passage that . A. TCM is not exact in curing diseases B. 10 TCM centers abroad are all set up by locals C. 86 countries have cooperated with China on TCM D. Tu Youyou’s success contributes to the popularity of TCM 3. According to Bernhard Schwartlander, TCM should . A. combine western medicine B. face no challenge at all C. give an exact description of its effects D. complete with western medicine 4. Which of the following can be the best title of the passage? A. A report on TCM B. Opinions about TCM C. TCM & Western Medicine D. Traditional healing spreads (三) Around the world, eggs have been a breakfast staple(重要部分)for all good reasons. After all, an egg is a storehouse of vital nutrients, making it an essential part of a healthy diet. And for those of you who are afraid of having this power food because you're worried that it will add to your weight, remember, one egg contains about 80 calories and about five grams of fat. Hence, smart consumption is a far healthier option. Eggs are a well-known rich source of protein — an important building block of bones, muscles, skin, and blood. The body uses protein to build and repair tissues as well as making other body chemicals. Unfortunately, unlike fat and carbohydrates(碳水化合物), the body does not store protein, and therefore has no reservoir to draw on when it needs a new supply. Thus eggs are the perfect sources and a smart food choice for those who reduce their intake of carbohydrates in a bit to lose extra weight. Another important nutrient you'll find abundantly in egg white is riboflavin or Vitamin B2. And for all of you wondering what's the benefit of this nutrient, Riboflavin is a water-soluble(水溶性) vitamin which is involved in vital processes in the body and is necessary for normal cell function, growth, and energy production. The yolk, which many of us avoid out of fear, is actually a very healthy food, if consumed in moderation(适度). Mainly fat, the yolk contains 1.33 gm of cholesterol(胆固醇) per 100 gms and is a rich source of vitamin A, B vitamins, calcium, phosphorous(磷) and iron. Incidentally, the iron found in the yolk is easily digested in the body. According to nutrition experts, one can eat one whole egg every day without harming one's cholesterol and other blood-fat levels. But for those who crave for more eggs, you can reduce fat by having one whole egg and the whites of the rest of the eggs. 1. Eggs are regarded as important in breakfast because__________. A. it is a custom to have eggs in the breakfast. B. they are sold at a low price. C. they are high in calories and low in fat. D. they can provide people with many nutrients. 2. When our body is short of protein, we may____________. A. feel tired and sleepy. B. feel discomfort in our legs. C. get tired of eating eggs. D. be eager for other chemicals. 3. Which of the following is true about protein? . A. It can’t be stored in the body. B. Fat can be changed into protein. C. It is a kind of carbohydrate. D. Our body can only get protein from eggs. 4. We can infer from the last paragraph that____________. A. the author suggests we only eat the whites of eggs. B. eating enough yolk can reduce cholesterol in the body. C. iron and phosphorous in the yolk are difficult to digest. D. high blood-fat level can do harm to our health (四) The crisis(危机) at Japan’s Fukushima Dai-Ichi nuclear(核) energy center caused by the terrible earthquake has raised questions about the future of the nuclear energy industry. Arjun Makhijani is president of the Institute for Energy and Environmental Research in the United States. He says the disaster(灾难)in Japan is historic. This week, the chairman of America’s nuclear agency said there is little chance that harmful radiation(辐射) from Japan could reach the United States. Gregory also said America has a strong program in place to deal with earthquake threats. No new nuclear power centers have been built in the United States since nineteen seventy-nine. That was when America’s worst nuclear accident happened at the Three Mile Island center in Pennsylvania. The accident began to turn public opinion against nuclear energy. At present, about twenty percent of electricity in the United States comes from nuclear energy. German Chancellor Angela Merkel said Germany would close seven nuclear power centers while energy policy is reconsidered. The European Union is planning to test all centers in its twenty-seven member nations. Developing nations are less willing to slow down the development of nuclear (nuclear expansion). China said it will continue with plans to build about twenty-five new nuclear reactors(反应堆). And India, under a cooperation agreement with the United States, plans to spend billions on new centers in the coming years. Nuclear reactors supply fourteen percent of global electricity. Nuclear energy is a clean resource, producing no carbon gases. But radioactive waste is a serious problem to be solved (unresolved issue). So is the presence of nuclear power centers in earthquake areas like the one near Bushehr, Iran. 1.We can learn from the text that America________. A.experienced a terrible nuclear accident 32 years ago B.has a strong program to deal with radiation danger C.depends heavily on nuclear energy to produce electricity D.will check all the reactors before cooperating with India 2.According to the text, which country will be most likely to have a similar disaster? A.German. B.Iran. C.India. D.China. 3.How does the author seem to feel about the future of nuclear energy? A.Satisfied. B.Pleased. C.Worried. D.Surprised. 4.The best title of the text is _________. A.Various Opinions on Japan's Nuclear Disaster B.Japan's Disaster is Likely to Run out of Control C.America Feels Great Concern for Japan's Nuclear Crisis D.Japan's Disaster Throws Doubt on Nuclear Energy Industry (五) According to researchers, money can buy happiness, but only if you spend it on someone else. Spending as little as $5 a day on someone else could significantly bring you happiness, the team at the University of British Columbia and Harvard Business School found. Their experiments on more than 630 Americans showed they were measurably (适度地) happier when they spent money on others--even if they thought spending the money on themselves would make them happier. “We wanted to test our theory that how people spend their money is at least as important as how much money they earn,” said Elizabeth Dunn, a psychologist at the University of British Columbia. They asked their 600 volunteers first to rate their general happiness, report their annual income and detail their monthly spending including bills, gifts for themselves, gifts for others and donations to charity. “Regardless of how much income each person made, those who spent money on others reported greater happiness, while those who spent more on themselves did not,” Dunn said in a statement. Dunn’s team also surveyed 16 employees at a company in Boston before and after they received an annual profit-sharing bonus of between $3,000 and $8,000. “Employees who devoted more of their bonus to pro-social (有益社会的) spending experienced greater happiness after receiving the bonus, and the manner in which they spent that bonus was a more important predictor of their happiness than the size of the bonus itself,” they wrote in their report, published in the journal Science. They gave their volunteers $5 or $20 and half got clear instructions on how to spend it. Those who spent the money on someone or something else reported feeling happier about it. “These findings suggest that very minor alterations in spending allocations (分配) --as little as $5--may be enough to produce real gains in happiness on a given day,” Dunn said. 1.According to the passage, ________. A. the more money you spend on others, the happier you are B. spending money on others can bring you happiness C. Elizabeth Dunn is a psychologist from Harvest Business School D. six hundred volunteers took part in the experiment 2.The 16 employees mentioned in the passage _________. A. were given clear instructions on how to spend the bonus B. had more happiness than the size of the bonus itself C. experienced greater happiness after receiving their bonus D. felt happier after they contributed much of the bonus to charities 3.Dunn’s statement suggested that ________. A. those who spent money on others felt happier no matter how much they earned B. those who spent more money on themselves felt happier C. people thought spending money could make themselves happier D. the money spent was as important as the money earned 4.The best title of this passage is ________. A. Experiment on Money Spending B. Devoting Your Money to Charities C. Spending Money on Others Makes One Happier D. Bonus and Pro-social Spending (六) Smog in Europe and North America could be more than 25 times more deadly than the average air pollution found in Chinese cities, a new study suggests. In the largest ever study of its kind in the developing world, researchers tested the effects of air pollution on the health of people in 272 cities in China. They found average annual exposure to fine particles, known as PM2.5, in those cities was more than five times higher than the level recommended by the World Health Organization (WHO), according to a paper in the American Journal of Respiratory and Critical Care Medicine. However they also discovered that it was much less likely to increase the death rate than PM2.5 in Europe and North America. The researchers, led by Dr Maigeng Zhou, of the Chinese Centre for Disease Control and Prevention, suggested this was because China is affected by large amounts of natural dust blown by the wind from arid areas, while most pollution in the West comes from industry. They found that for every increase of 10 micrograms of air pollution in a cubic meter of air, the mortality rate increased by 0.22 percent, discounting deaths from accidents. Professor Frank Kelly, an expert in environmental health at King’s College London, who was not involved in the study but has studied air pollution in China, told The Independent: “Those relative risks are considerably less than those seen in Europe and the US. For mortality(死亡率)in Europe we are working on a six percent increase per 10 micrograms.” That suggests air pollution in Europe is about 27 times more toxic than average air pollution in China. However, Professor Kelly said cities like Beijing, Shanghai and Hong Kong were likely to suffer from Western-style air pollution. "The natural dust component there is not of the magnitude that it would dwarf the coal, biomass and fossil fuel signals,” he said, “That may be true in certain cities whose pollution is not dominated by local power generation or major traffic congestion.” Natural dust particles can cause physical damage to the lungs and trigger an asthma attack. Particles of carbon produced when fossil fuels are burned can lead to similar problems but they are also coated with toxic heavy metals, chemicals and volatile organic compounds. These are able to pass from the lungs into the blood stream where it is thought they cause further damage to the body. Areeba Hamid, an air pollution campaigner with environmental group Greenpeace, said: “Poisonous air causes damage to people’s health wherever in the world they live. We now know fumes from diesel(柴油机) vehicles are a lot more poisonous than car companies claimed and this is a big cause of air pollution in Europe and North America. These companies have a lot to answer for, but so far they’ve managed to avoid any real accountability.” The study of cities in China found the average annual expose to PM2.5 was 56 micrograms per cubic meter, compared to the WHO guideline limit for safe air quality of 10 micrograms. People who were older than 75, had less education or who lived in hotter places were more likely to die. It is thought people in warmer cities were more likely to spend time outside or leave their windows open, thereby breathing more polluted air, the researchers said. They also speculated that less well educated people might have poorer access to health care or experience poorer environmental health conditions. 1. Why PM2.5 in China is less deadly than that in Europe and North America? A. China is free from any pollution about PM2.5. B. Pollutants affecting China mainly come from arid areas. C. Fewer people died from PM 2.5 in China than those in Europe and North America. D. Europe and North America are polluted by natural dust. 2. What does the underlined part in Para 7 refer to? A. The average mortality rate. B. The higher mortality rate. C. The lower mortality rate. D. The normal mortality rate. 3. What’s the real cause of air pollution in Europe and North America according to Areeba Hamid? A. Fumes from diesel vehicles are much more poisonous. B. The environmental agencies can’t take on responsibilities. C. The technology doesn’t meet the standards. D. Car companies can’t evaluate the results. 4. The author’s purpose of writing the passage is to ________. A. appeal to people to lay an emphasis on environmental protection. B. illustrate smog in Europe and North America is quite serious. C. demonstrate China is safest place in the world to live in. D. provide some good ways to address the smog. (七) OSLO ( Reuters) -Six of the world's eight bear species are under threat of extinction after the addition yesterday of the sun bear, the world's smallest type of bear, to a "Red List" which says China's panda is most at risk. The sun bear is threatened partly by poachers(偷猎者) who sell its bile(胆汁)as medicine, said the World Conservation Union which runs the list of the threatened wildlife. "Things are getting worse for all the bear species except the American black bear which is unquestionably increasing," said Simon Smart, senior species adviser for the Union. The addition of the sun bear to the authoritative "Red List" after a major review means the American black bear and the brown bear, found from Europe to Alaska, are the only two of eight species still considered robust(强的) . The sun bear, found in Asia from Bangladesh to Borneo and weighing up to about 70kg, was rated "vulnerable(脆弱的) " by experts at the Union,which consists of more than 80 governments, conservation groups and scientists. The union said there were several thousand sun bears in the wild. "We estimate that sun bears have declined by at least 30 percent over the past 30 years, and continue to decline at this speed," said Ron Steinmetz, head of the Swiss- based Union's sun bear expert team. Scientists did not change the level of threat to any bear species (except sun bears). Deforestation, loss of habitat to roads and cities and poaching are among risks. The Asian black bear, the sloth bear and the Andean bear were all proved again as vulnerable after reassessment of land-living bears. The polar, the only species not reassessed, is separately rated as vulnerable. Pandas were regarded again as endangered, one step closer to extinction than vulnerable, in spite of China's protection efforts for the bamboo-eaters. 1. How many kinds of threats are particularly mentioned to bear species? A.2. B.3. C.4. D.5. 2 According to the text, pandas . A. are in the greatest danger of extinction on the "Red List" B. are in less danger of extinction now with the China's protection efforts C. are one step closer to extinction than ever before D. are not among the 8 bears mentioned in the text 3. We can infer from the text that . A. the World Conservation Union is not in charge of protecting wildlife in the world B. pandas are rated as endangered after the reassessment C. there are several kinds of land-living bears in the world D. sun bears remain " vulnerable ", compared with 30 years ago (八) Over millions of years, penguins(企鹅)have developed a keen sense of where to find food. Once they’re old enough, they set off from the shores on which they were hatched for the first time and swim long distances in search of tasty fish like anchovies and sardines. But they don’t search directly for the fish themselves. For example, when young African penguins head out to sea, they look for areas with low surface temperatures and high chlorophyll(叶绿素) because those conditions signal the presence of phytoplankton(浮游植物). And lots of phytoplankton means lots of plankton(浮游动物), which in turn means lots of their favorite fish. Well, that’s what it used to mean. Climate change plus overfishing have made the penguin feeding grounds a mirage(海市蜃楼). The habitat is indeed plankton-rich—but now it’s fish-poor. Researchers call this an “ecological trap.” “It’s a situation where you have a signal that previously pointed an animal towards good quality habitat. That habitat’s been changed, usually by human pressures. The signal stays, but the quality in the environment deteriorates.” Richard Sherley, a zoologist at the University of Exeter and his team used satellite imaging to track the African penguins from eight sites along southern Africa. Historically, the birds benefited from tons of fish off the coasts of Angola, Namibia and western South Africa, but now they’re going hungry. “I was really hoping we’d see them going east, and finding areas where the fish had moved to but it ends up being quite a sad story for the penguins.” said Richard. The researchers calculate that by falling into this ecological trap, African penguin populations on South Africa's Western Cape have declined by around 80 percent. Some research groups are exploring the idea of moving chicks to a place where they can’t get trapped, like the Eastern Cape. But Sherley thinks that a longer-term solution means making and carrying out rules to create more sustainable(可持续的) fishing industry, something that he says needs public support. 1. How do penguins find their food? A. They discover fish with their keen sense. B. They swim long distances directly for fish. C. They make signals to each other when finding fish. D. They look for warmer and greener areas. 2. What is an ecological trap for the African penguins? A. A trap set to catch penguins. B. A good fish habitat with few fish. C. A habitat unsuitable for fish. D. A mirage on the sea. 3. What does the underlined word “deteriorates” in the fourth paragraph mean? A. Get worse. B. Get better. C. Stay the same. D. Become suitable. 4. What can be done to help the penguins in the long run? A. Move the penguins to other places. B. Create nature reserves for penguins. C. Keep a balanced fishing industry. D. Increase the population of penguins. (九) For hundreds of millions of years, turtles (海龟) have struggled out of the sea to lay their eggs on sandy beaches, long before there were nature documentaries to celebrate them, or GPS satellites and marine biologists to track them, or volunteers to hand-carry the hatchlings (幼龟) down to the water’s edge lest (for fear that) they become disoriented by headlights and crawl towards a motel parking lot instead. A formidable wall of bureaucracy has been erected to protect their prime nesting on the Atlantic coastlines. With all that attention paid to them, you’d think these creatures would at least have the gratitude not to go extinct (die out). But Nature is indifferent to human notions of fairness, and a report by the Fish and Wildlife Service showed a worrisome drop in the populations of several species of North Atlantic turtles, notably loggerheads, which can grow to as much as 400 pounds. The South Florida nesting population, the largest, has declined by 50% in the last decade, according to Elizabeth Griffin, a marine biologist with the environmental group Oceana. The figures prompted Oceana to petition the government to upgrade the level of protection for the North Atlantic loggerheads from “threatened” to “endangered”—meaning they are in danger of disappearing without additional help. Which raises the obvious question: what else do these turtles want from us, anyway? It turns out, according to Griffin, that while we have done a good job of protecting the turtles for the weeks they spend on land (as egg-laying females, as eggs and as hatchlings), we have neglected the years spend in the ocean. “The threat is from commercial fishing,” says Griffin. Trawlers (which drag large nets through the water and along the ocean floor) and longline fishers (which can deploy thousands of hooks on lines that can stretch for miles) take a heavy toll on turtles. Of course, like every other environmental issue today, this is playing out against the background of global warming and human interference with natural ecosystems. The narrow strips of beach on which the turtles lay their eggs are being squeezed on one side by development and on the other by the threat of rising sea levels as the oceans warm. Ultimately we must get a handle on those issues as well, or a creature that outlived the dinosaurs (恐龙) will meet its end at the hands of humans, leaving our descendants to wonder how creature so ugly could have won so much affection. 1. We can learn from the first paragraph that ________. A.human activities have changed the way turtles survive B.efforts have been made to protect turtles from dying out C.government bureaucracy has contributed to turtles’ extinction D.marine biologists are looking for the secret of turtles’ reproduction 2.What does the author mean by “Nature is indifferent to human notions of fairness” (Line 1, Para. 2)? A.Nature is quite fair regarding the survival of turtles. B.Turtles are by nature indifferent to human activities. C.The course of nature will not be changed by human interference. D.The turtle population has decreased in spite of human protection. 3. What constitutes a major threat to the survival of turtles according to Elizabeth Griffin? A.Their inadequate food supply. B.Unregulated commercial fishing. C.Their lower reproductively ability. D.Contamination(pollution) of sea water 4. How does global warming affect the survival of turtles? A.It threatens the sandy beaches on which they lay eggs. B.The changing climate makes it difficult for their eggs to hatch. C.The rising sea levels make it harder for their hatchlings to grow. D.It takes them longer to adapt to the high beach temperature. (十) Forest are amazing and so are the animals that live in them. We enjoy watching TV shows about bears, bats or monkeys. We know a lot about their lives: how they find food or what they do at different times of the year. But what about smaller animals that are more difficult to see or film? Many small animals that live in forests are very important for the soil. A French scientist, Francois Xavier Joly, is studying one of them — the millipede(千足虫). The importance of leaves When the leaves begin to die in fall, they turn from green to yellow and fall from the trees. As they decompose on the ground, nutrients(营养物质) are returned to the soil and carbon dioxide to the air. Life in the forest needs these nutrients. Without them, plants could not grow and there would be no food for animals such as the millipede. Food on the forest floor Some living things, like mushrooms, break the leaves into smaller pieces and eat them. In a few months there is nothing left of them. But for mushrooms, not all trees are the same. Mushrooms prefer some types of leaves to others. This means that some leaves take much longer to be broken down than others. Sometimes it takes years. So what happens to these? This is where the millipede can help. More on the menu The millipede also likes leaves and it eats any type. But when it has finished, it produces waste. This waste then becomes the food of mushrooms. When mushrooms eat leaves they choose only certain types but when they eat waste, they will eat any kind. This is how the millipede turns dead leaves into food for others and helps life continue. So next time you are walking through a forest, remember that something may be having a meal right under your feet. 1. According to the passage, what can we learn about the millipede? A. It can often be seen on TV shows. B. It mostly feeds on the nutrients in the soil. C. It is too small to be noticed by people. D. It lives under mushrooms in the forest. 2. What does the underlined word "decompose" in Paragraph 3 mean? A. Break down. B. Dry up. C. Dig in. D. Make out. 3. What does the author want to tell us by mentioning mushrooms? A. The millipede eats mushrooms in the forest. B. The millipede helps to provide food for mushrooms. C. Mushrooms play an important part in helping millipedes out. D. Mushrooms decide what types of leaves the millipede will eat. 4. According to the author, the millipede is . A. poisonous B. rare C. unimportant D. amazing 参考答案 1、CBAC 2、 DDAD 3、DBAD 4、ABCD 5、BDAC 6、BCAA 7、BAC 8、ABAC 9、BDBA 10、CABD查看更多
