[课下练熟高考] 阅读理解·组块专练——练速度 (限时:35分钟) Ⅰ.阅读理解 A Want to help fight global warming? Take off your tie, says the Italian health ministry. It has urged employers to let their staff dress casually at work in the summer so that the air conditioning can be turned down. “Taking your tie off immediately lowers the body temperature by 2 or 3 degrees centigrade,” the ministry said in a statement. “Allowing a more sensible use of air conditioning brings about electricity savings and protects the environment.” It called on all public and private offices to let employees wear no tie during heat waves like the one that has brought Africalike temperatures to many parts of Italy this week. The move echoes (回应) a similar action from Italy's biggest oil group, ENI, which told its staff earlier this month they need not wear a tie at work. The tie makers, however, were left hot_under_the_collar. “Italy confirms that it is a strange country,” Flavio Cima said angrily in a letter to financial daily Il Sole 24 ORE under the headline: “I, tie maker, am responsible for global warming.” “We can now happily continue with our lifestyle, using cars, consuming fuel, heating and cooling our homes at leisure. On one condition: we should not wear a tie while we do so,” he wrote. “I should have listened to my friends and become an oil producer instead.” Italy is one of the European Union's worst performers on the pollution front and is among the EU countries expected to exceed (超出) their greenhouse gas emission (排放) targets. 语篇解读:本文是一篇夹叙夹议文。解掉领带可以让体温下降2或3度,所以许多公司鼓励员工不戴领带上班,以抵制全球气候变暖;但是,这种主张遭到了领带制造商的反对。 1.What's the purpose of the move of taking off ties? A.To dress casually. B.To fight global warming. C.To keep the body temperature. D.To improve working conditions. 解析:选B 主旨大意题。根据第一段中的“Want to help fight global warming? Take off your tie”可知,解掉领带是为了抵制全球变暖,故B项正确。 2.Who first encouraged employees to take off ties? A.ENI. B.Flavio Cima. C.A financial daily. D.The Italian health ministry. 解析:选A 细节理解题。根据第五段中的“ENI, which told its staff earlier this month they need not wear a tie at work.”可知,ENI公司最早鼓励员工上班时不戴领带,故A项正确。 3.What does the underlined part “hot under the collar” in Paragraph 6 probably mean? A.Angry. B.Speechless. C.Delighted. D.Puzzled. 解析: 选A 词义猜测题。根据第四段和第五段可知,包括ENI在内的许多公司,都鼓励员工不戴领带上班;根据常识可以判断,此举势必造成领带制造商的商品滞销;结合第七段的“Flavio Cima said angrily in a letter”可以判断,画线部分意为“愤怒的”,故A项正确。 4.Which of the following is TRUE about Flavio Cima? A.He stands by the oil group. B.He agrees with the ministry. C.He admits his responsibility. D.He argues against taking off ties. 解析:选D 推理判断题。根据第六、七段可知,对于鼓励员工不戴领带上班一事,作为领带制造商的Flavio Cima非常生气;据此可以判断,他对不戴领带上班的观点有异议,故D项正确。 B The Spotlight in Rio Phelps puts spotlight on cupping (拔火罐) Olympic gold medalist Michael Phelps led American swimmers to a gold medal in the 4×100meter relay, but what grabbed media attention and led to stories and photos around the globe were the purple and red circles on his back. Michael Phelps of the USA is seen with red cupping marks on his shoulder as he competes during the 2016 Rio Olympics men's 200m butterfly in Rio de Janeiro, Brazil, Aug 8, 2016. Chinese swimmer Fu Yuanhui goes viral China's women's swimmer Fu Yuanhui has created a sensation online not just by winning the bronze medal in the 100m backstroke competition, but also by her facial expressions during the post semifinal interview with China Central Television (CCTV) on Monday. When asked whether she held back for the final, Fu replied, “No, I utilized my ‘prehistorical power’.” What she meant was that she had spared no efforts in the semifinal. Since then, the socalled “prehistorical power” has gone viral and become a new Internet meme. Britain wins first Olympic diving gold in men's synchronized 3m springboard (男子双人3米跳板) Britain's Jack Laugher and Chris Mears ended China's gold medal monopoly (垄断) over diving events at the Rio Olympics by winning the men's synchronized 3m springboard final on Wednesday, the country's firstever Olympic gold medal in diving. Laugher and Mears finished with a sixround total of 454.32 points, just 4.11 points ahead of silver medallists Mike Hixon and Sam Dorman of the USA at the Maria Lenk Aquatics Center. China's Cao Yuan and Qin Kai took the bronze with 443.70 points. 5.What attracted media attention with Phelps' winning the gold medal? A.His great leadership. B.His scars on his back. C.The cupping marks on his back. D.His achievements he made in the men's 200m butterfly. 解析:选C 细节理解题。根据第一则新闻中的“what grabbed media attention ...and red circles on his back”以及“Michael Phelps of the USA is seen with red cupping marks on his shoulder”可知随着菲尔普斯获得金牌,他后背上的拔火罐的印迹成为媒体关注的重点。故选C。 6.Which of the following is NOT the reason why Fu Yuanhui became the spotlight? A.Her devotion and determination to swimming. B.Her achievement in the 100m backstroke competition. C.Her facial expression during the postsemifinal interview. D.Her humourous reply to the reporter — so called “prehistorical power”. 解析:选A 细节理解题。根据第二则新闻可知让傅园慧成为焦点的不仅是她的成绩,更是她在赛后接受采访时的面部表情和她的“我已经用了洪荒之力了”的幽默回答。故选A。 7.What can we learn from the third news? A.China didn't win any gold medals in diving events at the Rio Olympics. B.Britain became the gold medal monopolist of diving events at the Rio Olympics. C.Mike Hixon and Sam Dorman of the USA took silver with 447.81 points. D.Britain had never won the Olympic diving gold medal before the Rio Olympics. 解析:选D 判断推理题。根据第三则新闻中的“Britain's Jack Laugher and Chris Mears ended China's gold medal monopoly (垄断) ... Olympic gold medal in diving.”可知英国的跳水员Jack Laugher和Chris Mears获得了男子双人3米跳板的金牌,这是英国有史以来第一次获得奥运会跳水项目的金牌。故选D。 C People need to seek out new foods because the world has so many mouths to feed. As of 2015, there are more than seven billion people on Earth, according to the United Nations. And by 2100 that number may double. Feeding all of these people means not only improving the way foods are grown, but also finding new sources of nutrition. And that_quest is becoming ever more urgent. If nothing changes, within 35 years, the world's appetite will be greater than the amount of foods produced. That's according to a report released in 2014. It was prepared by the Global Harvest Initiative, a private agriculture group based in Washington, D.C. Global warming, too, is changing food production. Scientists predict that rising temperatures will reduce the growth of important crops like wheat, corn and soybeans. Lowincome developing countries will be hit the hardest. When harvests fall, crops become more expensive. And since those foods are also used to feed animals like cows and pigs, meat prices, too, will rise. All over the world, researchers are racing against the clock to figure out how best to feed more people in a fastchanging world. And some surprising ideas have begun to come up. Two years ago, scientists introduced the first burger made from meat grown in a lab. The project cost more than $300,000, but it's a start. Other researchers are developing seeds that can survive high temperatures and drought. Still others are finding ways to improve the genes of meat animals so they produce more meat and can stand the heat. A gloomy (悲观的) forecast for the planet isn't the only reason to study foods for the future. It's a creative quest that will inspire people who can think in new ways about existing plants and animals — even insects. These researchers have used their talents in ways that even they never would have predicted. 语篇解读:本文是一篇说明文。主要讲的是在全球变暖的环境下,人们应如何应对日益膨胀的人口的温饱问题。 8.What do the underlined words “that quest” in Paragraph 2 refer to? A.The research on foods. B.The increase of population. C.The variety of nutrition. D.The change of appetite. 解析:选A 词义猜测题。根据第一段最后一句及下文的食物研究可知,画线词指对食物的研究。 9.How does global warming affect lowincome developing countries? a.Increase meat prices. b.Raise the temperature. c.Reduce the growth of crops. d.Lead to the high cost of life. e.Cause a higher price for crops. A.b→a→c→d→e B.c→a→b→d→e C.d→e→c→a→b D.b→c→e→a→d 解析:选D 事件排序题。根据第三段的整体内容可知,全球变暖首先是导致气温上升,然后是农作物减产,从而农作物价格上涨,进而肉类涨价,最终会导致人们生活成本增加。 10.What is mainly talked about in Paragraph 4? A.New ways of farming. B.Some great researchers. C.Progress in food research. D.Achievements in lab experiments. 解析:选C 段落大意题。根据第四段第二句“And some surprising ideas have begun to come up.”并结合本段的整段内容可推知,本段主要讲述的是食物研究方面的进步。 11.What will be discussed in the following paragraph? A.Examples of successful food researchers. B.Different opinions about the future food. C.Methods of dealing with global warming. D.Possibilities of feeding the present population. 解析:选A 推理判断题。根据最后一段最后一句“These researchers have used their talents in ways that even they never would have predicted.”并结合本段的整体内容可推知,下文会举一些成功的食物研究者的例子。 D (2017·长春一模)China's online dealers (零售商)are busy preparing for what has become the country's annual online shopping festival on November 11th. November 11 is a date made up of four ones, and “double eleven” has always been considered a special day for single men and women in China. Five years ago the Internet retailer Alibaba began promoting it as a shopping festival, and it has now turned to be the country's busiest day for online retailers and millions of shopping lovers. JD.com is trying to attract more retailers by offering them free delivery service for a month. Alibaba itself has invited some 30,000 offline stores to participate in the online shopping party. More than 20,000 vendors on Alibaba's sites — Tmall and Taobao are promising 50 percent discounts on the day. Shanghaibased Yhd.com, also called Yihaodian, a Chinese ecommerce company that is majorityowned by WalMart Stores, is setting up a special sale of imported foods. Last year Alibaba earned 19.1 billion yuan in sales during the double eleven promotions. And a 100 billion yuan logistics (物流) network was set up by Alibaba this May that aims to make 24hour deliveries possible. The major logistics player Shentong shipped more than 8 million items during “double eleven.” Shentong has more than 150,000 staff, and expects things to be even busier this year. Yang Jinghai, Director Of Human Resources of Shentong Express, says, “We have hired 30 percent more staff for double eleven, and we have couriers' (快递员) bonuses ready.” On double eleven China's ecommerce sites receive more visits than the entire population of Brazil. It is believed that China will replace the US as the world's top ecommerce market this year. 语篇解读:本文是一篇说明文,介绍了中国各大购物网站为迎接“双十一”所做的各项准备。 12.What can we infer from the second paragraph? A.“Double eleven” is an official festival in China. B.Most people will go shopping online on “double eleven”. C.“Double eleven” is no longer a special day for singles in China. D.Online retailers will make a lot of preparations before “double eleven”. 解析:选D 推理判断题。根据第二段的“a shopping festival”及“the country's busiest day”,可知选D。 13.What kind of situation are you most likely to meet if you buy things online on “double eleven”? A.You will get a 50% discount. B.You will find more goods online. C.You are not able to buy imported goods.
