2019-2020学年成都市三中高三英语下学期期中考试试卷及参考答案
2019-2020学年成都市三中高三英语下学期期中考试试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AThe Origins of Famous BrandsOur lives are full of brand names and trademarked products that we use every day. Although many brand names are simple acronyms(首字母缩略词) or versions of their founders names, some of the companies we trust every day actually have fascinating and surprising back stories.StarbucksIt seems fitting that the most famous coffee brand in the world would take its name from one of the world’s greatest works of literature. The inspiration for the name of the coffeehouse came from Herman Melville’sMoby Dick. The founders’ original idea was to name the company after the Captain Ahab’s ship, but they eventually decided that Pequot wasn’t a great name for coffee, so they chose Ahab’s first mate, Starbucks, as the name instead.GoogleGoogle was originally called Backrub, for it searched for links in every corner of the Web. In 1997, when the founders of the company were searching for a new name showing a huge amount of data for their rapidly improving search technology, a friend suggested the word “googol”. When a friend tried to register the new domain (域) name, he misspelled “googol” as “google”.NikeOriginally founded as a distributor for Japanese running shoes, the company was originally named BRS, or Blue Ribbon Sports. In 1971, BRS introduced its own soccer shoe, a model called Nike, which is alsothe name for the Greek goddess of victory. In 1978, the company officially renamed itself as Nike, Inc.The right name is essential to a company’s success, and a great origin story is just as important as a great product. An attractive origin story is one more thing that keeps customers guessing, wondering, and buying its products.1. What is the name of the Captain Ahab’s ship?A. Moby Dick.B. Starbucks.C. Pequot.D. Herman Melville.2. Why did the founders of the Google want to change its name?A. They mistook their name.B. They wanted new customers.C. The company’s original name was too long.D. The company’s search technology was improving rapidly.3. Where does the importance of the origin story of one company lie in?A. It can change the company’s image.B. It can add myth to the company.C. It explains the development of the company to customers.D. It makes customers imagine and purchase its goods.BYou’re in a crowd of people who are all asking for the same thing. How do you make your voice heard above the rest? Be different. Don’t shout. Lisa, 25, was waiting to board a plane flying fromLondontoAustriafor Christmaswhen the flight was cancelled.“There were about a hundred of us unable to leave,” she says. “Everyone else was shouting at the airport staff. Instead of joining in, I walked up to the man behind the ticket desk very quietly and said, ‘This must be so awful for you! I don’t know how you deal with these situations—it’s not even your fault. I could never handle it as well as you are.’ Without my even asking, he found me a seat on another airline with an upgrade to first class. He was happy to do a favor forsomeone who was appreciative instead of unfriendliness.”Flattery (恭维) is an essential element of the sweet-talk strategy. “It’s human psychology that stroking a person’s ego (自我) with a few well-directed praises makes them want to prove you right,” says apsychologist. “Tell someone they’re pretty and they’ll instantly fix their hair; praise their sense of humor and they’ll tell a joke.”You need help and there’s ly no reason that the person will want to lend a hand. Allison, 26. a lawyer, realized she’d made a huge mistake on a batch of documents. “The only way I could fix the problem was to get the help of a colleague who I knew didn’t like me,” she said.Allison then went to the woman’s office and explained her problem. “As I was saying to the boss the other day you’re the only person who would know how to handle a situation like this, what would you suggest I do?” “Feeling pumped up (鼓励), she set about helping me and we finished the job on time, and she was happy to help.” Allison said.4. Whatwould have happened at the airport according to paragraph 1?A. The departure hall was filled with noise.B. Someone screamed just lo be different.C. The passengers waited on board patiently.D. The airport stuff were rude to the passengers.5. Why did the man put Lisa on another airline?A. He admired Lisa’s beauty.B. He appreciated her attitude.C. He was ready to help others.D. He was blamed for the cancellation.6. What is the third paragraph mainly about?A. The potential benefits of ego.B. The strategy to start small talk.C. The great importance of flattery.D. The value of humor in daily life.7. What can we learn about Allison’s colleague?A. She was a popular lawyer.B. She was always ready to help others.C. She always got praise from Allison.D. She did a great favor for Allison eventually.CHumans are the only creature that gets around by standing up and putting one foot in front of the other. Our ability to walk upright has allowed humankind to travel great distances and survive changing climates, environments and landscapes.Countless scientific studies have found that walking is really good for us and this simple act can provide a number of healthimplications, which help people live longer. In fact, a walking routine, if done properly, might be the only exercise people need.How much walking should one aim for? You’ve likely heard we need 10,000 steps a day. That’s about 5 miles. But contrary to popular belief, this recommendation doesn’t come from science. Instead, itis from a 1960s advertising campaign to promote a pedometer (计步器) in Japan. Perhaps because it’s a round number and easy to remember, it stuck.Since the 1960s, researchers have studied the 10,000-steps-a-day standard and have turned up mixed results. Although 10,000 steps is certainly a healthy and worthwhile goal, it’s not fit for all.For instance, a recent Harvard University study involving more than 16,000 senior women found that those who got at least 4,400 steps a day greatly reduced their risk of dying early when compared with less active women. The study also noted that these benefits continued up to 7,500 steps. This 7,500 mark isn’t surprising: It’s similarto common public health recommendations, such as the Centers for Disease Control and Prevention’s recommendation of 150 minutes of moderate (适度的) physical activity a week for adults.8. What does the underlined word “implications” in Paragraph 2 refer to?A. BenefitsB. Problems.C. Habits.D. Manners.9. Where does the 10,000-steps-a-day standard come from?A. A Harvard University study.B. Science research on health.C. A pedometer advertisement.D. Public health recommendation.10. What can we know from the last paragraph?A. 7,500-steps-a-day standard is the best choice for all.B. More than 16,000 old people were involved in the study.C. Those who walk at least 4,400 steps a day won’t die early.D. 150-minute moderate exercise a week for adults is advised.11. What does the author mainly want to tell readers?A. The more you walk a day, the healthier you will be.B. We can benefit from continuous and proper walking.C. Walking upright helps humankind to explore the world.D. Advertisements can always tell us some scientific suggestions .DA world in which extinct creatures could be brought back to life came a step closer yesterday. Australian scientists have managed to extract a gene from a preserved sample of a Tasmanian tiger and make it active. Thebreakthroughhas left them dreaming that one day they will be able to recreate the animal, which died out more than 70 years ago. And if it can be done with the Tasmanian tiger, it may also be possible to resurrect (复活) creatures that have been extinct for far longer.“There used to be a time when extinction meant forever, but no more, ” said Professor Mike Archer. “We are now able to seriously challenge whether those animals that have gone for ever. What has been achieved is a very important step in bringing back those animals that are extinct. And while I think that technically it is still pretty difficult at the moment, we can now see the possibilities. I’m personally convinced that the Tasmanian tiger will bebrought back to life in my lifetime.”The breakthrough came after nine years of experiments by scientists at the University of Melbourne, who extracted a gene from one of several tigers preserved in alcohol in a Melbourne museum. They removed the equivalent gene from a mouse embryo implanted the tiger gene and then watched as the mouse continued to grow normally, suggesting the tiger gene had been activated.Team leader Dr. Andrew Pask said it was the first time DNA from an extinct species had been used to “induce (引起) a functional response in another living organism”.However, the animal’s entire gene structure would have to be revived in the same way to even begin the possibility of bringing the Tasmanian tiger back from the dead.Mick Mooney, a wildlife officer ofthe Tasmanian Government, was worried that such developments could encourage people’s indifference to the protection of endangered species.“If people think that we can bring animals back to life after they’ve gone, they will start saying that there is nothing to worry about because we can fix it up later.”12. What does the underlined word “breakthrough” in the l paragraph refer to?A. Scientists have recreated new animals.B. Scientists have resurrected endangered animal.C. It has turned out that some creatures would not go extinct.D. A tiger gene has been extracted successfully and activated.13. Scientists are carrying out the experiments in order to ________.A. bring extinct animals back to lifeB. transplant the genes of tigers into other animalsC. find out what factors lead to the animals’ extinctionD. find a new way to extract animals’ DNA14. Mike Archer thinks that ________.A. scientists now have no technological difficulty reconnecting extinct animalsB. it’ll be a century or so before a Tasmanian tiger walks on the earth againC. humans have come closer in reconnecting extinct animalsD. reconnecting extinct animals is impossible15. We can learn from Mick Mooncy’s words that_________.A. he thought it unnecessary to worry about endangered animalsB. his opinion is in contrast with that of the Tasmanian GovernmentC. he thought people should be encouraged to protect endangered animalsD. he is concerned that bringing extinct animals back to life may have a negative effect第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2019-2020学年成都市三中高三英语下学期期中考试试题及答案
2019-2020学年成都市三中高三英语下学期期中考试试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ABook reading is certainly one of the most absorbing habits. For young adults who love to read, finding some good books to read is very essential. Writing a book review can help you to improve your language and writing skills.The Book ThiefListed onThe New York Times Children’s Best Seller List for over 100 weeks, The Book Thief by Markus Zusak is the story of a young girl in the Nazi camps set during World War II. So, if you love history and wish to learn how the life was during Adolf Hitler’s time, read this historic book.The Diary of Young GirlEven Anne Frank can not have imagined that her personal diary written during World War II would become such a popular book. It’s a must read that describes the situation of a family in the evils of wars through the eyes of a teenager.Animal FarmAnimal Farm is one of the most popular books by George Orwell. It is just a reflection of the Stalin and World War II period that has been so creatively presented in this book. It is an interesting example of how literature can be used to present conditions common in the society.Adventures of Huckleberry FinnMark Twain’s Adventures of Huckleberry Finn is one of the great American novels in history, and is certainly a great pick for young adults. Young Huck Finn and his mischief along with the color1 ful description of people around theMississippi Rivermake this novel a great book to read.1.Which book describes the author’s own experiences according to this passage?A.The Book ThiefB.The Diary of Young GirlC.Animal FarmD.Adventures of Huckleberry Finn2.What do the first three books have in common?A.All of them are about wars.B.All of them are about farms.C.All of them are intended for history lovers.D.All of them were written during World War II.3.The purpose of this passage is to _________.A.instruct youngsters how to improve skillsB.tell youngsters some wonderful reading habitsC.introduce several good books to youngstersD.give youngsters advice on writing a book reviewBNow most of the workers work from 9 am to 5 pm. However, according to the global Internet survey done by the UK Sleep Council, thesiesta（午睡）was the right idea all along. The UK Sleep Council called on the country'sbosses to end nine-to-five working in favor of more flexible hours. They believe what would really increase the workers' productivity is a nice afternoon nap, rather than those bonuses.Forty-one percent of the 12,000 people who responded to the council's survey said they were most productive in the morning, while 38 percent said theyhit their stridein the evening. "This means most of them cannot fully pay attention to what they do in the middle of the day," said sleep expert Dr. Chris Idzikowskii. "We must conclude from this survey that the traditional nine-to-five working day does not suit most workers." He suggested that allowing workers to follow their natural sleeping habits would actually benefit employers by allowing them to expand their working hours and be more productive.Fortunately, being a college lecturer, I don't have to go to work everyday. I only work three days a week, but during the three days I work really long hours and have no time for a little siesta. I'm usually so tired and sleepy in the afternoon, which really affects thevitality（活力）of my classes.I think Dr. Chris Idzikowskii's idea is worthwhile. When people have flexible working hours they could reach their highest productivity. On top of that, flexible working hours mean thatpeople don't have to work all at the same time. That way we could avoid traffic jams. Therefore, it's really killing two birds with one stone!4. What can improve the workers' productivity, according to the UK Sleep Council?A. More bonuses.B. The flexible working time.C. Working for long hours.D. Working in a relaxing way.5. What does the underlined part probably mean in Paragraph 2?A. Were most sleepy.B. Were most flexible.C. Worked at their own pace.D. Worked at their best.6. What did the UK Sleep Council's survey find?A. Few people are suitable to work at noon.B. People are more productive in the morning.C. Some people like to expand their working hours.D. More and more people prefer to work in the evening.7. Why does the author support Dr. Chris Idzikowskii's idea?A. It could solve most of the traffic problems.B. He finds Dr. Chris Idzikowskii respectable.C. He thinks the idea can benefit the society.D. It allows him to work for fewer hours.CWhena person in the United States gets the COVID-19 vaccine (疫苗), the person receives a small piece of paper called a “COVID-19 Vaccination Record Card”.It is a piece of paper with the logo of the Centers for Disease Control and Prevention, or CDC, and the name and date of the vaccine. Because it is so simple, it could be easy to fake.Many people in theU.S.are still unsure about getting the vaccine. As universities, workplaces and other places are requiring proof of vaccination, some people are now buying fake vaccination cards without getting a shot.The Associated Press reports that students and teachers at universities around theU.S.are worried about fake cards. Sellers are using social media apps like Instagram to advertise fake vaccination cards. The prices range from $25 to $200. The AP notes that many college students seem interested in buying the cards. On the site Reddit, one person wrote, “I need one, too, for college. I refuse to be a guinea pig.”It is reported that more than 700 universities and colleges require proof of vaccination. Most schools simply ask their students to take a photo of their card and send it to a school website. Benjamin Mason Meier is a professor at theUniversityofNorth CarolinaatChapel Hill, UNC. He studies international health policy. He said, unlike some countries, theU.S.is not using a digital system to record vaccine status. He said theU.S.is depending on “aflimsypaper card”, and students have told him they knew of others who had used fake vaccination cards. Rebecca Williams also works at UNC. She is a researcher at the school’s Center for Health Promotion and Disease Prevention. She said she was not surprised that people were worried about fake vaccination cards. “This is why I think the development of a reliable national digital vaccine passport app is very important,” she said.There is a law that should prevent people from making false vaccination cards. If someone uses the CDC logowithout permission, they can be lined and punished by up to five years in prison. The U.S. Department of Justice recently charged a person inCaliforniawith making fake vaccination cards.College students who already have the vaccine are criticizing those who would rather spend money to buy a fake than get a free shot. Maliha Reza is an electrical engineering student atPennsylvaniaStateUniversity, She called those students “dumb”. “I’m angry about that,” she said. “Like, there is more anger than I could describe now.”8. Why do some college students buy fake vaccination cards?A. They are easy to get.B. Many Americans are still uncertain about getting the vaccine.C. Students have an interest in the fake vaccination cards.D. To get a vaccine shot is expensive.9. Which of the following measures can NOT be used to stop the fake cards?A. Having a law that should prevent people from making false vaccination cards.B. Developing a reliable national digital vaccine passport app.C. Using a digital system to record vaccine status.D. Having all the students take a photo of their vaccination card and send it to the school website.10. What does the underlined word “flimsy” probably mean?A. Weak.B. Effective.C. Detailed.D. Professional,11. What might be the writing purpose for the news report?A. To promote a digital system to record the vaccination shots.B. To explain why theU.S.should prevent making the fake vaccination cards.C. The stress the influence of the COVID-19 vaccination.D. To reduce theU.S.university leaders’ worry about fake vaccination cards.DJapan's prime minister encouraged the decision to ban viewers, even family members, by issuing a state of emergency order in Tokyo earlier this month in response to rising COVID-19 case numbers.From the perspective of sports psychologists, an Olympics without fans is a real-life science experiment that is helping researchers and clinicians to comb through the true impact of a crowd of fans on its players—and on viewers at home. The strange circumstances under which the games are held may place unexpected pressure onsome athletes. On Tuesday, superstar gymnast Simone Biles dropped out of the women's team event, telling teammates and reporters she wasn't in the right “headspace” to compete. “It's been really stressful this Olympic Games. There are a lot of different variables going into it,” Biles told the Washington Post.The 2020 Summer Olympics bears similarities and differences to other major sporting events without viewers. The English Premier League supplemented (增加) game broadcasts with crowd noise from the soccer video game FIFA 20, mixed with game audio in real time. A Taiwanese baseball team and German soccer team began populating stands with cardboard cutouts of fans, and the trend caught on internationally.Jamey Houle, the lead sports psychologist for Ohio State University Athletics and a former Al-American gymnast, says competitive athletes are trained in visualization— imagining performing a certain action or motion, such as doing a roundoff back handspring in gymnastics. Without moving a muscle, players using visualization can solidify neural (神经的) connections and activate their motor cortex (皮层). To visualize most effectively, Houle says, athletes working with sports psychologists will try to simulate as closely as possible the conditions of actual gameplay. Empty stadiums may thus have a measurable impact on players' performance. This phenomenon is grounded in a psychological concept called “social facilitation”, referring to a change in a person's performance that occurs when others are around compared to when a person is alone.12. What caused Biles to drop out of the women's team event?A. The poor physical condition.B. The absence of the audience.C. The fiercely competitive event.D. The influence of crowds of fans.13. What can be inferred from Paragraph 3?A. The Taiwanese baseball team is a success.B. The tendency mentioned is popular among some sporting events.C. The 2020 Summer Olympics is stricter in preventing the pandemic.D. The crowd noise plays a leading role in the English Premier League.14. How does Houle explain the impact of empty stadiums on players' performance?A. By doing a roundoff back handspring.B. By simulating the conditions of actual gameplay.C. By using the concept called social facilitation.D. By changing the viewers of a player.15. What message does the author mainly convey in the text?A. Athletes should be trained in visualization.B. Audience should be admitted to the Olympics.C. Social facilitation is helpful to sporting events.D. Viewers present may influence players' performance.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

中国人很早便与茶发生关系了。
《诗经•谷风》中的“谁谓荼苦，其甘如怡”的“荼”许多人便认为是“茶”。
西汉初马王堆墓葬中的随葬品中即有茶叶。
不过两汉以前，茶不是作为一种饮料存在，而是一种“菜肴”。
晋代郭璞为《尔雅》作的注中曾说道茶“叶可煮作羹饮”。
作羹自然少不了油盐酱醋、姜桂葱椒等调料，还要用一些碾碎的米粉勾芡。
现在，在某些地区还有其遗孑存在，如湘西的“擂茶”、陕西的“三炮台”、洛阳的“罐罐茶”等等，这些都是介于饮料与菜肴之间的。
茶的“文人士大夫化”或说“雅化”是由唐代的“茶圣”陆羽完成的。
他的那部《茶经》不仅总结了前代饮茶的经验并加以提高与规范化，其中充满了士大夫的审美情味。
这是世界茶的历史上第一部系统论茶的著作，是茶的“雅化”的标志，至今仍被全世界的茶人们奉为经典。
唐代主要饮的是饼茶，它由茶叶蒸、捣、拍、焙等方法制成，在煮茶之前还要烘烤、碾碎，在釜中煮沸而饮。
在烹煮和品饮过程中，所用器具也是饮茶艺术的重要组成部分。
陆羽还研制了十分细致考究的二十四种茶具，大都小巧玲珑，可以贮存在一个美观的笼中，携带方便。
使得“远近倾慕，好事者家藏一副”，与现在仍在日本流行的茶道类似，当然那是极富诗意的艺术品。

Because often people aren't as honest and open as they should be. Sometimes, people end up getting hurt.Most problems with friendships come up because people are just too selfish to care about the things that their friends need. They care about their own needs much more, which makes it hard for friendships to work. However, being selfish is part of human nature. A person is put together in order to take care of himself and his own needs, not necessarily those needs of other people. Even though being selfish is something that all humans are born with, it is something that everyone should guard against.The best thing to remember when you are a friend to anyone is that you need to treat your friend the same way as you'd like to be treated. This is wonderful advice for a friendship, because it is really the only way to make sure that you are giving your friend everything you would want to be given in a friendship. Whenever you have a question about how you should treat a friend, it is easy to find an answer simply by asking yourself what you would like your friend to do for you, if he or she is in your shoes.Even if you're always thinking about how you'd like to be treated, and your friends are too, there are issues that come up from time to time in each friendship, and it is important to understand how to deal with these issues so that you can build stronger and healthier friendships. Issues like friends getting boyfriends or girlfriends and not spending enough time with their friends, or even friends finding new friends and leaving old friends behind are issues that will probably come up with one or more of your friendships. It is important to know how to deal with these issues so that you can keep your friends and make new ones. No one wants to have a broken friendship.8. Why may problems with friendships appear?A.

Study author Brent Coker said, “Surfing the Internet at times helps increase an employee's attention.”“People need to relax for a bit to get back their attention,” Coker said on the university's website. “Having a short break, such as a quick surfing of the Internet, helps the mind to rest itself, leading to a higher total Internet attention for a day's work, and as a result, increases productivity (生产效率),” he said.According to the study of 300 workers, 70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours. Among the most popular surfing activities are searching for information about products, reading online news, playing online games and watching videos. “Firms spend a lot of money on software toblocktheir employees from watching videos, using social networking sites or shopping online,” said Coker. “That's not always a good idea.”However, Coker said the study looked at people who surfed the Internet in moderation (适度), or were on the Internet for less than 20 percent of their total time in the office. “Those who spend too much time surfing the Internet will have a lower productivity than those without.” he said.12. What does the University of Melbourne study mainlyshow?A. People who surf the Internet are good employees.B. Not everyone surfs the Internet for fun during office hours.C. The Internet is becoming more and more important in people's life.D. Surfing the Internet for fun at times during office hours increases productivity.13. Which of the following is NOT mentioned in the passage as one of the most popular surfing activities?A. Watching videos.B. Reading online news.C. Reading online novels.D. Playing online games.14. The underlined word “block” in Paragraph 4 means “________”.A. stopB. organizeC. protectD. separate15. What can we infer from the last paragraph?A. Those who never surf the Internet have the lowest productivity.B. Spending too much time surfing the Internet reduces productivity.C. Most people don't surf the Internet in moderation during office hours.D. People should spend as little time as possible surfing the Internet.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
2020-2021学年成都市三中高三英语下学期期中考试试卷及参考答案
2020-2021学年成都市三中高三英语下学期期中考试试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AWhile Jennifer was at home taking an online exam for her business law class, a monitor（监控器）a few hundred miles away was watching her every move.Using a web camera equipped in Jennifer'sLos Angelesapartment, the monitor inPhoenixtracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked remotely to prevent Internet searches, and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past？Or was she slowing down？In the battle against cheating, this is thecutting edgeand a key to encourage honesty in the booming field of online education. This technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid — that students haven't searched the Internet to get the right answers.Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses". Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone numbers they once used.Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.1. Why was Jennifer watched in an online exam?A. To correct her typing mistakes.B. To find her secrets in the room.C. To keep her from dishonest deeds.D. To prevent her from slowing down.2. What does the underlined expression "cutting edge" in Paragraph 3 probably mean?A. sharpening toolB. advanced techniqueC. effective ruleD. dividing line3. How can some programs find out possiblecheaters?A. By scanning the Internet test questions.B. By checking the question answering speed.C. By producing a large number of questions.D. By giving difficult test questions.BI’ve long believedthat positive living isn’t about being optimistic every minute of every day. That kind of permanently happy state can’t be the goal, because it’s impossible to achieve.It turns out that psychological research finds true happiness comes from authentic positivity, and authentic positivity comes from emotional flexibility.Being flexible emotionally means being open to the full range of emotional experiences, including the challenging ones like anger, disappointment and sadness. Emotional flexibility means being able to shift behaviors and mindsets to meet different situational needs, and adapting when circumstances change.However, emotionally flexible people are not chameleons (变色龙) whose outlook changes based on which way the wind is blowing. Instead, emotional flexibility is a skill that helps people judge the complexities of daily life, and stick to their deeply held values.I’ve learned a new word that I’d like to share with you: Eudaimonia (幸福感). Eudaimonia is the opposite of hedonism (享乐主义), the idea that happiness comes from the constant pursuit of pleasure and avoidance of pain. Eudaimonia, by contrast, encourages us to pursue meaning and authenticity, growth and honest joy. Both are philosophical approaches to happiness, and recent psychological thought is leaning toward eudaimonia as a more sustainable, satisfying model.Eudaimonia was first mentioned by Aristotle, who got the term from the Greek word “daimon,” which means “true nature.” Tome, walking a positive path means accepting that we each have positive true nature and permanent goodness. What we learn from the concept of eudaimonia is that we are best equipped to realize this nature when we are emotionally honest and flexible.4. What is the author’s belief?A. People should live alone.B. People can’t always be happy.C. People can’t always achieve their goals.D. People should pursue true achievements.5. What do enmotionally flexible people commit themselves to?A. Their strongly believed values.B. Their different needs.C. Permanent happiness.D. The pursuit of hedonism.6. How can people gain eudaimonia according to the author?A. By being honest to others.B. By changing true nature.C. By keeping realstically optimistic.D. By pursuing pleasure constantly.7. Which of the following is a suitable title for the text?A. What is the meaning of eudaimonia?B. What should we do to keep positive?C. How can we keep happy forever?D. Why can’t people be happy all the time?CWhy can friendships be hard? Because often people aren't as honest and open as they should be. Sometimes, people end up getting hurt.Most problems with friendships come up because people are just too selfish to care about the things that their friends need. They care about their own needs much more, which makes it hard for friendships to work. However, being selfish is part of human nature. A person is put together in order to take care of himself and his own needs, not necessarily those needs of other people.

Alvin Irby was at a barbershop when he saw one of his former students sitting in the shop with a bored look on his face. That’s when Irby realized that by pairing barbershops and books, he might be able to inspire young boys to read.Alvin Irby, a former kindergarten and first-grade teacher, knows how important it is for young children to read. He also knows that young boys in particular often don’t have adult male role models who inspire them to read. “Many young boys may literally never see a man reading in school during the years when they’re learning to read because there are so few male elementary school teachers,” Irby toldMashable.That’s where the barbershops come in. Four years ago, Irby launched Barbershop Books as a way to not just get books into the hands of young boys, but also to create community reading spaces in a place where kids go frequently. Since itsinceptionin 2013, the program has created kid-friendly reading spaces in 50 barbershops in 12 states throughout the United States.Irby isn’t the first person to see the connection between barbershops and books and boys. Hair stylist Courtney Holmes, launched a program a few years ago offering free haircuts to kids as long as they read to him while he cuts their hair.That’s the kind of environment that Irby wants to promote with his program. The reading spaces created by Barbershop Books help to spark an interest in books by showing kids that reading is about more than just spelling and vocabulary skills, it’s about making reading a low-stress activity that can help them relax, laugh and have fun.“Our belief is that if we can create positive reading experiences early and often for young boys, then they will choose to read for fun,” Irby noted, adding, “This is really what Barbershop Books is about, getting young boys to say three words: I’m a reader.”12. What happened to Alvin when he was at a barbershop?A. He found it easy for young people to get bored.B. He offered a barbershop to his former student.C. He thought of a way to encourage young readers.D. He realized the importance of reading for young boys.13. What is the function of Barbershop Books?A. To attract more customers who love films.B. To provide free haircuts to book lovers.C. To show the influence of reading on children.D. To create a reading environment fbr children.14. It can be inferred from the passage that ________.A. reading is a low-stress activity that is relaxingB. Barbershop Books is only suitable for young boysC. Irby attaches great importance to school educationD. Barbershop Books can arouse (引起) young people’s interest in reading15.

A new study finds that happiness comes from exercise. People who exercise actively bring themselves happiness equal to earning an extra $25,000 ayear.Instead of recording extra hours at work in hopes of getting a raise, maybe you should hit the gym instead, as it could make you just as happy as that extra money. An interesting new study, published in the Lancet, found that people who are physically active have a greater sense of well—being than those who are inactive-and that active individuals feel as good as inactive people who earn $ 25,000 more per year.Researchers from Oxford and Yale Universities used data gathered from more than 1.2milion Americans. They were asked, “How many times have you felt mentally unwell in the past30 days. for example, due to stress, depression, or emotional problems?” Participants were also asked about their exercise habits and were able to choose from 75 diverse physical activities, including doing housework and childcare, running, weightlifting, and cycling. The researchers found that people who exercise regularly feel bad for an average of 35 days per year, while inactive people feel bad for an additional 18 days.All exercise types were associated with a lower mental health burden. Social physical activities（that is to say, team sports such as football, basketball, etc）had an even more positive effect, which can best help people relax mind.It is possible for some to get too much exercise. From Business Insider'sreport on the study. “The mental health of those participants who exercised for longer than three hours a day suffered more than that of those who weren't particularly physically active.” The ideal amount seems to be three to five training sessions per week. lasting 30 to 60 minutes each.But the conclusion should be that any amount helps, so don't stress about hitting that perfect balance: “All exercise types were associated with a lower mental health burden than not exercising.”4. The question asked in Paragraph one is meant to ______.A. introduce the researchersB. tell the secretC. draw a conclusionD. lead to the topic5. Which exercise below can help us relax mind most effectively?A. RunningB. Walking alone.C. Playing footballD. Keeping fit in the gym.6.

The more exercise you take, the higher mental health burden you will get.C. overdoing exercising will do harm to people's mental health.D. doing exercise is better than not doing it.7. What is the main idea of the passage?A. Exercise can bring as much pleasure as an income rise.B. The secret of happiness has nothing to do with wealth.C. Choosing the right form of exercise is of vital importance.D. The key to keep young is to exercise regularly.CIvrea is a town in the Piedmont province of northern Italy. It is known for its localcarnival（狂欢节）organized in February.The main part of the carnival is the famous Battle of the Oranges (La battaglia delle arance). The Battle includes nine teams who throw oranges at each other during three carnival days – Sunday, Monday and Tuesday.Oranges were not always used in the battle. In the middle ages people used beans. Twice a year the local feudal lord gave a pot of beans to the poor families who, as sign of rebellion, threw them out of their homes. Later beans became part of carnival as sort of “ammunition” for throwing at people passing by.It is still not known why exactly people started using oranges. It is believed that the origin for this tradition is in the mid 19th century. The legend says that local girls, standing on balconies, started to throw some oranges, together with confetti,lupins(白羽扇豆)and flowers, onto the parade carriages. The girls actually wanted to draw attention of boysin the carriages. Boys “answered” by throwing some objects back at girls. Little battle started that way.Battle of the Oranges got strict rules after the World War II. The battles are organized on town's squares. The battles are fought between teams in carriages (symbolizing local the guards of localtyrant(恶霸)) and the teams walking beside those carriages (symbolizing rebellious people of Ivrea).Oranges for the event are brought from the island of Sicily. The oranges used are of low quality, not suitable for humans. About 270,000 kilograms of oranges are used each year.The carnival ends with a silent march on the night of “Fat Tuesday”. The Carnival "general" says goodbye to everyone with the phrase "See you next Fat Thursday at 1 p.m."Special prizes are awarded to three best foot teams, three carriages drawn by two horses and three carriages drawn by four horses. Different elements are judged like for example throwing ability, fair play or decoration of carriages.8.

2020届成都市第八中学高三语文下学期期中考试试题及答案解析
2020届成都市第八中学高三语文下学期期中考试试题及答案解析一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文字，完成下面小题。
新媒体是继报刊、广播、电视等传统媒体以后发展起来的新的媒体形态，是利用数字、网络技术、移动技术，通过互联网、无线通信网、有线网络等渠道以及电脑、手机、数字电视机等终端，向用户提供信息和娱乐的传播形态和媒体形态。
目前，新媒体主要包括电脑网络媒体、手机媒体、网络电视、电子出版物等。
相对于传统媒体，新媒体具有传播与更新速度快、信息量大、全球性和跨文化性、检索便捷、多煤体、超文本、互动性、成本低的优势，给传统纸质媒体带来巨大冲击。
媒体的命运取决于它在社会上扮演的角色和所起到的作用。
如果纸质媒体的功能完全被其他媒体替代，它将无法生存，如果纸质媒体能够具有其他媒体所不具有的功能，就有存在的价值。
阅读是人类获取信息的主要途径，纸质媒体和新媒体可以看成完全不同的两种阅读方式。
稳定的空间感，逻辑严密、线索清晰、便于记忆和思考，是纸质媒体阅读的优势；新媒体的阅读者更多的是一种信息的快速获取，记忆和思考退居次要地位。
从这个意义上看纸媒体与电子媒体的关系，就不是一个取代另一个的单向演变，而是一种阅读方式与另一种阅读方式的区别。
两种阅读方式的不同也给纸媒体和新媒体带来了长期竞争共存的空间。
借助于现代计算机技术，新媒体实现了高密度的信息储存，单位信息存储成本低，可以方便地实现大量信息的自动化处理，使得部分编辑工作为机器所替代，极大地降低了制作成本；电子信号的易复制性和快速传播性，使其发行成本低廉，使大范围信息传播免费或廉价提供成为可能。
但分析新媒体传播内容可见，新媒体传播的信息具有传统媒体的一般特征，和传统媒体没有质的区别。
大部分内容源于传统媒体，最突出之处，也仅是在传统媒体的基础上做了一些计算机技术的加工，实现了声音、画面、文字的同时传播。
可见新媒体在传播中所具有的纸质媒体难以实现的优势，主要源于其对先进的传播技术的应用。

2020-2021学年成都市三中高三英语下学期期中考试试卷及答案
2020-2021学年成都市三中高三英语下学期期中考试试卷及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AExperts say that if food were a country, it would rank second behind theUSas one of the biggest greenhouse gas polluters. The reason is the rising demand for meat. Animal farming is responsible for 14.5 percent of global methane emissions. While cowsare the worst contributors, pigs, sheep, donkeys and other animals play a part as well.Animal agriculture also causes land to become damaged, water to be polluted and forests to get destroyed. With the world population forecast to rise to 9.8 billion by 2050, things are only looking worse for our already decreasing natural resources. While going vegetarian would help, meat consumption is too deep-rooted in most Western diets to allow for such a sharp, permanent change. That is why experts are advocating substituting some of the beef, chicken, or pork with ordinary insects!Insects, which grow into adults within a matter of months, if not weeks, are ready for consumption much faster than domestic animals. They also require much less room, use less water and food, and produce far less greenhouse gas than animals.Of the 1.1 million insect species worldwide, scientists have identified 1,700 as eatable. Among them are ants, grasshoppers, grubs, and earthworms. Just like animals, each insect has a different taste. Tree worms taste just like pork, and grubs are similar to smoked meat.While eating insects might be a new concept for Western people, over 2 billion people worldwide consume insects as a regular part of their diet. Besides being delicious, insects are high in protein, have very few calories, and are free of the saturated fat found in animal meat. Insects can be prepared in many ways. Creative cooks can use them to cook protein-rich soup, make baked treats, and even fry a few with vegetables. So eat insects--- both your body and Mother Earth will thank you for it!1. Which of the following animals contribute the most to global methane emissions?A. Sheep.B. Donkeys.C. Cows.D. Pigs.2. How is the third paragraph developed?A. By making comparisons.B. By providing examples.C. By listing data.D. By asking questions.3. What can be inferred from the last paragraph?A.Few people eat insects regularly.B. Ordinary insects are high in fat.C. Insects contain various vitamins.D. Saturated fat is harmful to health.BThose who are concerned that robots are taking over the world can rest easy—for now. Though the androids have proved useful at performing ordinary tasks, they are not ready for the greatest time. At least that appears to be the case atJapan’s Henn-na Hotel chain where over half of the robot staff are being replaced by humans.The first location of the unique hotel opened in July 2015 was atNagasaki’s Huis Ten Bosch Theme Park. The hotel’s owner, Hideo Sawada, promised the hotel to be managed primarily by robots. Guests were greeted and checked-in by a dinosaur robot, while a cute android called Churi, placed inside each room, provided information about attractions. Not surprisingly, the lodging, recognized in 2016 as the world’s first robot-staffed hotel by Guinness World Records, drew in curious visitors from all around the world.But as the years have passed, the hotel’s main draw is becoming less novel and more unsatisfactory. Also as the robots are “aging”, they are costing more to repair. Among the 283 androids being replaced are the chain’s two dinosaur receptionists. In addition to scaring young guests, they are also unable to photocopy guests’ passports, forcing human employees to step in each time. Also out are the cute Churi robots, which annoyed guests by interrupting their conversations. For example, one guest told The Wall Street Journal that Churi mistook his snoring for a command and kept asking him to repeat his request all night.Sawada told The Wall Street Journal, “When you actually use robots you realize there are places where they aren’t needed—or just annoy people.” While Sawada may be cutting back on his use of androids, the recently-opened Smart LYZ Hotel and the Fly Zoo Hotel inChina, are run entirely by robots, with not a human in sight. Whether the employees have more competence than those “hired” by the Henn-na Hotel chain remains to be seen.4. What makesJapan’s Henn-na Hotel unique?A. Its robot employees.B. Its advanced equipment.C. Its convenient location.D. Its successful management.5. What is the author’s purpose with the example in paragraph 3?A. To entertain readers.B. To prove Churi’s drawback.C. To introduce Churi’s functions.D. To persuade people not to book the hotel.6. What does the owner ofJapan’s Henn-na Hotel think of his robot staff now?A. Attractive.B. Costly.C. Pioneering.D. Disappointing.7. What is the best title for the text?A. Robots Are Taking Over the World.B. The Boom of Robots-staffed Hotel.C. Robot Staff Are Fired For No Competence.D. The First Robots-staffed Hotel Won Guinness World Record.CNASA has flown an aircraft on another planet for the first time. On Monday, April 19, Ingenuity, a 1. 8-kilogram drone (无人机) helicopter, took off from the surface of Mars, flew up about threemeters, then hovered for 40 seconds and took photos above with one of its two cameras. The historic moment was livestreamed on YouTube. “We can now say that human beings have flown a drone helicopter on another planet,” said MiMi Aung, the Ingenuity Mars Helicopter project manager at NASA's Jet Propulsion Laboratory, at a press conference. “We, together, flew at Mars, and we, together, now have our Wright brothers moment,” she added, referring to the first powered airplane flight on Earth in 1903.The details: The flight was a significant technical challenge, thanks to Mars' s bone-chilling temperatures (nights can drop down to -130 °F / -90 °C) and its incredibly thin atmosphere — just 1% the density of Earth' s. That meant Ingenuity had to be light, with rotor blades (螺旋桨) that were bigger and faster than would be needed to achieve liftoff on Earth (although the gravity on Mars, which is only about one-third of Earth's, worked in its favor). The flight had originally been scheduled to take place on April 11 but was delayed by software issues.Why it's significant: Beyond being a significantmilestonefor Mars exploration, the flight will also pave the way for engineers to think about new ways to explore other planets. Future drone helicopters could help astronauts by scoping out locations, exploring inaccessible areas, and capturing images. Ingenuity will also help inform the design of Dragonfly, a car-size drone that NASA is planning to send to Saturn's moon Titan in 2027.What's next: In the next few weeks, Ingenuity will conduct four more flights, each lasting up to 90 seconds. Each one is designed to further push the limits of Ingenuity's capabilities. Ingenuity is only designed to last for 30 Martian days, and is expected to stop functioning aroundMay 4. Its final resting place will be in the Jezero Crater as NASA moves on to the main focus of its mission: Getting the Perseverance rover (毅力号火星探测器) to study Mars for evidence of life.8. Why does MiMi Aung mention Wright brothers?A. To honor the historic contribution of Wright brothers.B. To make a comparison between Wright brothers and herself.C. To highlight the importance of Ingenuity's Martian exploration.D. To remind the public of the first powered airplane flight on Earth.9. What caused challenges for Ingenuity designers?A. The delay of software tests.B. The force of gravity on Mars.C. Mars's temperatures and atmosphere.D. Technical difficulty in liftoff on Earth.10. What does the underlined word “milestone” in Paragraph 3 probably mean?A. A great victory.B. A difficult task.C. A roadside stone.D. A historic event.11. Which of the following can be a suitable title for the text?A. Mars Drone Helicopter Makes Historic First FlightB. Modern Wright Brothers Moment: Mars ExplorationC. First Drone Helicopter Spots Evidence of Life on MarsD.

People originally thought the dog had been abandoned, but then realized that he looked healthy, so people asked around about him. It turned out that the dog had indeed been spending most of his time around that crossroad, but a woman had been coming round regularly to bring him food and water.One day, while photographing the dog everyone called Leo, a reporter met the woman who had been taking care of him. She had come to drop off some food. After learning the story about the dog and the woman, the reporter decided to share the story on social media.

What should a runner do to get an award according to the text?A. Make a good start．B. Plan for the race early．C. Run slowly on the starting line．D. Try runningquickly all the time．5. What formed the basis for Aftalion's studying horse race?A The experience and data from previous horse races．B. The benefit of knowing horses' different abilities．C. The success in studying runners' winning strategies．D. The performance of horses on different race distances．6. What does the underlined word“devastating”in the last paragraph mean?A. Boring．B. Damaging．C. Astonishing．D. Puzling．7. What can we infer from the text?A. Runners have the same energy output of muscles．B. Aftalion's findings may help horses to win the race．C. What Jockeys and trainers do makes no sense to horses．D. World champion runners made a contribution to the study．CDepression（抑郁症）in young adult males, ages 18 or 19, is linked to a 20% greater risk of having a heart attack in middle age, according to a new Swedish study.The link can be partly explained by poorer stress resilience（抗压能力）and lower physical fitness among teens with mental disorders.Theresearch included 238,013 men born between 1958 and 1962 who were given examinations in adolescence（青春期）and were then followed into middle age（up to the age of 58 years）. A total of 34,503 men were diagnosed（诊断）with a mental disorder.The study found thata mental disorder in young adulthond was linked to a higher risk of having heart attack by middle age. Compared to men without a mental illness in young adulthood，the risk of heart attack was 20%higher among men with a diagnosis.“We already knew that menwho were physically fit in adolescence seem less likely to keep fitness in later years if they have low stress resilience” said study author Dr. Bergh, “Our research has also shown that low stress resilience is also connected with a greater tendency towards bad behavior, such as higher risks of smoking, drinking and other drug use.”“Better fitness in adolescence is likely to help protect against later heart disease, particularly if people stay fitas they age. Physical activities may also reduce some of the bad effects of stress. Those in poor health could benefit from additional support to encourage exercise and develop plans to deal with stress,” said Bergh.8. How does the author develop paragraph 3?A. By giving examples.B. By listing figures.C. By making a comparison.D. By drawing a conclusion.9. What are men with low stress resilience likely to do?A. Smoke more.B. Eat more.C. Sleep less.D. Do less exercise.10. What will Bergh agree with according to the last paragraph?A. Physical activitiesadd to stress.B. Stress may cause heart disease.C. Taking exercise is unnecessary.D. Staying fit is of great importance.11. In which section of a newspaper may this text appear?A. Entertainment.B. Health.C. Education.D. Fashion.DPlanned missions to the moon need to hurry up to avoid hitting one of the busiest periods for extreme space weather, according to scientists conducting the most in-depth ever research on solar storm timing.Scientists at theUniversityofReadingstudied 150 years of space weather data to look into patterns in the timing of the most extreme events,which can be extremely dangerous to astronauts and satellites. This new research on space weather timing allows predictions to be made for extreme space weather. Therefore, it could be used to plan the timing of activities, which could be affected by extreme space weather, for example, major space missions.The researchers found for the first time that extreme space weather events are more likely to occur early in or late solar cycles-such as the one just starting. The findings may have influences on the NASA-led Artemis mission. It plans to make humans return to the moon in 2024, but can be put off to the late 2020s.Professor Mathew Owens, a space physicist at theUniversityofReading, said, “Until now, the most extreme space weather events were thought to berandomin their timing. Though there is no set pattern of the events, this research suggests they are more predictable.”In the new study, the scientists used a new method applying statistical modelling to storm timing for the first time. Previous research generally focused on how big extreme space weather events can be, based on observations of previous events. Predicting their timing is far more difficult because extreme events are rare, so there is ly little historic data to identify patterns. The findings suggest that any major planned space missions ,which is beyond the next five years, will have to consider the higher probability of extreme space weather late in the present solar cycle between 2026 and 2030.12. What can we learn about the study from the first two paragraphs?A. It has lasted just 150 years.B. It doesn't refer to space weather data.C. It shows space weather has no effect on astronauts.D. It makes it possible to predict extreme space weather.13. Why might the NASA-led Artemis mission be put off?A. To research solar cycles.B. To avoid effects of space weather.C. To meet the needs of the astronauts.D. To make humans return to Earth in 2024.14. What does the underlined word “random“ in paragraph 4 probably mean?A. Irregular.B. Easy.C. Limited.D. Changeless.15. What can we infer from the last paragraph?A. The study is useful for future space missions.B. The planned space missions should be put off.C. Extreme space weather will happen before 2026.D. Previous observations make no difference to the study.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2021年成都市第三中学高三英语下学期期中考试试题及答案解析
2021年成都市第三中学高三英语下学期期中考试试题及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AIt was a weeknight and one of my twin daughters marched into the room, waving a book she'd finished. “Dad, why are books with science in them always about boys?” she asked.I told her that simply wasn't true; there were loads of great science fictions with girls in them. She agreed, but argued that in those stories it was the boys who were doing science, and the girls were justalong for the ride. My other daughter took her sister's side and challenged me to give an example.This left me in a difficult position. I could either go through our library to point out some wonderful examples of female-led science fictions, or just admit they were right and remain in my comfortable chair.I've been asked several times how I came up with the idea forA Problematic Paradoxand my answer is always the same: it came to me in a moment of inspiration. I like that answer because it's simple and makes me seem very creative. The fact that this explanation is not true bothers me from time to time. Here's the truth: the story wasn't my idea. It was my daughters who suggested I write something for them that had a girl doing science.My daughters were at an age when many young women turn away from STEM (science, technology, engineering, and math), believing those areas of study unfriendly or out-of-the-norm for girls. I also read about how important role models can be to young people. It's one thing to tell a person they can do something, but seeing someone like them doing that thing can be more powerful.So, I kept two guidelines for the book in mind: First, the story had to be fun for anyone, because it's as important for boys to understand that science is for everyone. Second, I wanted the main character, Nikola, to be imperfect. She should be someone with shortcomings as we all have. I think this not only makes a story more interesting to read, but also helps make it clear that the most extraordinary things can be done by ordinary people.1. What does the underlined phrase “along for the ride” in paragraph 2 probably mean?A. Entering a bike race.B. Offering vital help.C. Doing unimportant things.D. Playing the leading role.2. What do we know about the bookA Problematic Paradox1?A. Its main character is perfect.B. It is a female-led science fiction.C. It is intended to appeal to girls only.D. Its idea comes from the author's inspiration.3. Which of the following best describes the author's book?A. Serious and abstract.B. Simple and practical.C. Creative and well-organized.D. Inspiring and interesting.BFor most thinkers since the Greek philosophers, it was self-evident that there is something called human nature, something that constitutes the essence of man. There were various views about what constitutes it, but there was agreement that such an essence exists—that is to say, that there is something by virtue of which man is man. Thus man was defined as a rational(理性的) being, as a social animal, an animal that can make tools, or a symbol-making animal.More recently, this traditional view has begun to be questioned. One reason for this change was the increasing emphasis given to the historical approach to man. An examination of the history of humanity suggested that man in our time is so different from man in previous times that it seemed unrealistic to assume that men in every age have had in common something that can be called “human nature.” The historical approach was strengthened, particularly in the United States, by studies in the field of cultural anthropology (人类学). The study of primitive peoples has discovered such a diversity of customs, values, feelings, and thoughts that many anthropologists arrived at the concept that man is born as a blank sheet of paper on which each culture writes its text. Another factor contributing to the tendency to deny the assumption of a fixed human nature was that the concept has so often been abused as a shield(盾牌) behind which the most inhuman acts are committed. In the name of human nature, for example, Aristotle and most thinkers up to the eighteenth century defended slavery. Or in order to prove the rationality and necessity of the capitalist form of society, scholars have tried to make a case for acquisitiveness, competitiveness, and selfishness as natural human characters. Popularly, one refers cynically（愤世嫉俗地）to “human nature” in accepting the inevitability of such undesirable human behavior as greed, murder, cheating and lying.Another reason for disbelief about the concept of human nature probably lies in the influence of evolutionary thinking. Once man came to be seen as developing in the process of evolution, the idea of a substance which is contained in his essence seemed untenable. Yet I believe it is precisely from an evolutionary standpoint that we can expect new insight into the problem of the nature of man.4. Most philosophers believed that human nature ________.A. is the quality distinguishing man from other animalsB. consists of competitiveness and selfishnessC. is something partly innate and partly acquiredD. consists of rationality and undesirable behavior5. The traditional view of “human nature” was strongly challenged by ________.A. the emergence of the evolutionary theoryB. the historical approach to manC. new insight into human behaviorD. the philosophical analysis of slavery6. According to the passage, anthropologists believe that human beings ________.A. have some characters in commonB. are born with diverse culturesC. are born without a fixed natureD. change their characters as they grow up7. The author mentioned Aristotle, a great ancient thinker, in order to ________.A. emphasize that he contributed a lot to defining the concept of “human nature”B. show that the concept of “human nature” was used to justify social evilsC. prove that he had a profound influence on the concept of “human nature”D. support the idea that some human characters are inherited.CContrary to the long-held belief that plants in the natural world are always in competition, new research has found that in severe environments adult plants help smaller ones and grow well as a result.The research, led by Dr Rocio, studied adult and seedling (幼苗)plants in the ecological desert in the south-east of Spain. Dr Rocio said, “If you're a seedling in a poor land — the top of a mountain or a sand hill, for example-and you’re lucky enough to end up underneath a big plant, your chances of survival are certainly better than if you landed somewhere on your own. What we have found, which was surprising, is an established large plant, called a ‘nurse’, protects a seedling; it also produces more flowers than the same plants of similar large size growing on their own.”Other benefits of nurse-seedling partnerships include that more variety of plants growing together can have a positive effect on the environment. For example, vegetation areas with nurse plants with more flowers might be able to attract higher numbers of pollinators(传粉者)in an area, in turn supporting insect and soil life and even provide a greater range of different fruit types for birds and other animals.“The biggest winner for this system of nursing a plant is biodiversity(生物多样性),” Dr Rocio said. “The more biodiversean area, the greater number of species of plants, insect life, mammals and birds, and the better the chances of long-term healthy functioning of the environment and ecosystems. ” This system is win-win for adult and seedling plants in unfavorable environments.The research is of value to those who manage and protect plants in tough environments. Most home gardeners and farmers plan to ensure their soil and conditions are the best they can be for plant growth, but the findings might be of value to those who garden in bare places.8.

The image (画像) hasn't changed much since the 1960s, but the person wearing the lab coat is changing.A new analysis finds that more female scientists have appeared in kids? drawings in recent decades — going from nearly nonexistent in the 1960s to about a third in 2016.The first of many “ draw-a-scientist ’’ studies asked nearly 5,000 children to draw a scientist between 1966 and 1977. Of those 5,000 drawings, only 28 drew female scientists. That was just 0.56 percent. Today, female scientists are being presented more in the media. For example, in a content analysis, 13 percent of people pictured in science feature stories of the 1960s were women or girls, compared with 44 percent in the 2000s. “That might really affect children’s idea on what a scientist should be like, ” says Miller, a Ph. D. candidate in psychology.To look for changes in children'sperceptionover time, the researchers conducted a meta-analysis ,combining data from 78 studies that included a total of more than 20,000 children from kindergarten to the 12th grade.On average, 28 percent of children drew female scientists in studies conducted from 1965 to 2016.What hasn’t changed much: kids pick up stereotypes (模式化观念）by gender (性别）as they grow up. At age 6, about 70 percent of the girls in the more recent studiesdrew female scientists. By age 16, 75 percent drew male scientists. This is an important period in which kids are learning stereotypes. It’s important that teachers and parents present diverse examples of both male and female scientists.12. What’s the picture of scientists drawn by a 1960s, kid like?A. A man with long curly hair.B. A woman with lab glasses.C. A woman in a formal lab suit.D. A man in a color1 ed lab coat.13.

2020年成都市三中高三英语下学期期中试卷及参考答案
2020年成都市三中高三英语下学期期中试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AThree Things to Do Before You Are 18Are you bored with your daily life? Here are some things you should try before you are 18.★Learn to swimSeriously, this is so important that it can save your life. If you can’t swim well, you won’t be able to dowater sports like waterskiing, surfing and diving. Even taking a boat trip will be dangerous for you. Make sure you do it.★Try at least one kind of team sportsBeing a good team player is an important skill in life. You can’t just think of yourself, but have to work well with other people. Other advantages of team sports like basketball, football and baseball are that they keep you fit and healthy, and they are also great fun. Teams usually have a good social life too—you’ll go to lots of parties and make many friends.★Collect somethingOne of the best hobbies for under-18s is collecting things. You could collect kinds of stamps, or you could collect things that make you remember what you have done, like cinema tickets for films you have seen or letters from friends. The best way to collect is to have a special album to put your collection in and to write what each thing means to you. That way you won’t forget.1. The most important reason for learning to swim is that ________.A. you might feel wellB. it can make you healthyC. you might easily do lots of thingsD. it can save your life2. The writer tells us that one of the best hobbies is to ________ .A. collect somethingB. do some water sportsC. send letters to your friendsD. play basketball with your friends23. The passage is mainly about ________before you are 18.A. good habits to keepB. skills to haveC. things to doD. sports to playBHave you ever noticed that some people can eat what they want and stay in shape, while others carefully watch what they eat and still put on weight? How annoying! However, scientists are beginning to believe that some people get the ability to stay thin from their parents.Scientists say that when some people eat, their bodies will naturally store the excess energy from food as fat. These people gain weight if they eat more than they need each day. Meanwhile, other people eat more than they need but their bodies are able to “burn off” the extra food without making fat, so they rarely have weight problems.To show that this is true, scientists have experimented on laboratory mice. They gave the mice a special diet with a lot of fat. Some mice gained weight while the other mice stayed thin, even though both groups of mice ate the same amount of food and got the same amount of exercise. Scientists concluded that weight gain seemed to be influenced by genetic (基因的) factors. They also believe they have now identified the genes that may cause this tendency. These genes, according to the scientists, get passed down the generations. Armed with this knowledge, they believe it may be possible to develop medicines thatcan target the genes and stop people from gaining weight.The study of weight gain is becoming more important as the numbers of people who are overweight continues to grow. In theUnited States, over seventy percent of the population have weight problems. This means they are at risk of illness such as high blood pressure and heart disease.Current medicines for weight control do not work very well because they can have serious side effects, such as heart problems. However, it takes a long time to develop and thoroughly test new drugs. Therefore, despite this breakthrough in the study of weight-loss drugs, scientists and health professionals all agree that currently the best way to control weight gain is to have a healthy, balanced diet and an active lifestyle with daily exercise. This will not only help people avoid becoming overweight, but also help them stay healthy and energetic.4. According to the scientists, some people ________.A. are able to stay thin because of genetic factorsB. can eat what they want and stay healthy foreverC. usually keep doing exercise to lose their weightD. don’t eat anything every day but still put on weight5. Some people don’t need to worry about weight problems because ________.A. they eat many vegetablesB. they eat less than othersC. they don’t store any energy from food as fatD. they can burn off the extra food without making fat6. What can we learn from the passage?A. Fewer people will have weight problems in the future.B. People with weight problems may suffer from heart trouble.C. We now have good medicine for people with weight problems.D. The result of the experiments on mice and humans are different.7. What does the last paragraph imply?A. Current medicine solve weight problems well.B. We should exercise regularly and eat properly.C. Taking exercise every day may cause heart problems.D. Testing new drugs is hard because of the side effects.CLearning to say “yes, and”When I first heard about the improvisation (即兴交流) class, I was hesitating. As a quiet and shy girl, I feared improvising in front of strangers. However,I knew I wanted to work as a science communicator after finishing my Ph.D., so it seemed like a perfect opportunity to learn how to speak and communicate with others effectively. I signed up, knowing the experience would give me help.During our first class, we learned an important concept of improvisation: “yes, and.” It means that, as improvisers, we’d better accept what fellow performers say. If someone says that rhinos (犀牛) are librarians, for example, then rhinos are librarians. We do not question the logic; we say “yes” and then continue with the scene as if nothing is wrong.The first few scenes were hard, but as weeks turned into months, I became more comfortable andeven started to enjoy our classes. I became better at listening, relating to my conversation partners, and communicating clearly in the moment. Once when I was giving a presentation about my science, an audience member surprised me with a question that didn’t grow out of the information I’d presented. Instead of getting confused and nervous, I took the “yes, and” approach—accepting the question and letting my mind focus on why it was asked. That helped me find an appropriate answer. I got pretty excited about it.The benefits of improvisation go beyond communication. Before attending the class, I would get stuck when my experiments produced unexpected data, thinking that I had made a mistake. But now, instead of gettingdiscouraged, I will stay open to the possibility that the results are real, keep exploring the data and end up identifying a new type of cell—one that isn’t behaving as expected.I think all scientists can benefit from this lesson. If the data say rhinos are librarians, then it’s worth findingout whether rhinos are, in fact, librarians. As scientists, our job isn’t to challenge data that support a preconceived (先入为主的) story, but to say “yes, and.”8. Why did the author attend the improvisation class?A. To get a different experience.B. To finish her Ph.D. at university.C. To give up her job as a science communicator.D. To improve her speaking and communicating ability.9. What was the author’s change after attending the improvisation class?A. She formed her own idea quickly.B. She came up with lots of creative responses.C. She paid more attention to the logic of answers.D. She became a good listener before giving an opinion.10. The author mentions applying the “yes, and” approach to her scientific experiments to ______.A. explain the process of using the methodB. prove the benefits of the improvisation classC. share her own research experiences with readersD. attract fellow scientists to attend the improvisation class11. What can be inferred about scientists from the last paragraph?A. They should attend the improvisation class.B. They should question all preconceived ideas.C. They should carry on research by admitting earlier data.D. They should try to improve their professional knowledge.DA single toy catches a child's attention for a limited period of time, but a box of items that allows a child to build their own toys will catch their imagination for years to come. This brilliant idea already exists in real product form, and it's called Toyi.Toyi is described as an eco-friendly creative building kit, and it recently won the well-known IF Design Award.It came from Istanbul, Turkish, where a young female designer named Elif Atmaca first came up with the idea for it when she wanted to help the kids living in disadvantaged areas. These children do not have access to the variety of interesting toys that wealthier children do.Toyi Atmaca's design allows children to transform what are around them into clever toys. It consists of sticks, junction parts, flexible connectors, toy body parts like feet, eyes, hands, and wheels that can be used to turn old water bottles, cups, boxes, towels, etc. into cute, clever, and unique playthings. This toy kit upcycles(升级利用) materials that would otherwise go to waste, turning a recycling bin into a treasure container.“Our initial target was to deliver Toyi kits to only disadvantaged children in Turkish,” Atmaca told the media. But during a research conducted with around300 children, .she realized that the restriction on being creative went beyond any boundary. “I saw that everything was planned and shaped by grown-ups, blocking the kids' imagination in a significant way,” said Atmaca.Atmaca concluded that each kid needed space where he or she could freely create. She explained the entire process should be left to kids’ creativity, reminding teachers and all grown-ups that child-led play was an excellent way for children to develop lifelong skills.Toyi's creators are now considering distributing the kits to as many children as possible around the world through different international NGOs. Atmaca notes that for each Toyi kit sold out, they will also donate one kit toa disadvantaged child through different partnerships around the world.12. Why did Atmaca design Toyi at first?A. To win the famous IF Design Award.B. To help poor kids make their own toys.C. To protect the environment in Istanbul.D. To recycle all the waste in the dustbin.13. Which is probably the product made with the toy kit of Toyi?A. A new picture of a young boy.B. A computer with high technology.C. A treasure container from a dustbin:D. A six-armed “robot” from a water bottle.14. How do the toy kits help improve the children's ability?A. It provides the kids various types of toys.B. It offers space for the kids’ creative minds.C. It changes the poor kids' living conditions.D. It teaches the kids to share joys with others.15. What is the new target for Atmaca and her partners?A. Donating toykits to more poor children.B. Selling toy kits to every kid in the world.C. Designing new toy kits for kids and adults.D. Doing further research on the kids' demands.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2021届成都市第三中学高三英语下学期期中试题及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AOne day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem inability to read.In the library,I found my way into the "Children's Room." I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle. Without opening the book—Amos, the Beagle with a Plan ,1 borrowed it from the library for the summer.Under the shade of a bush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. That dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book.I never told my mother about my “miraculous” experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year. And years later ,she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words has held.1. The author's mother told him to borrow a book in order to ________.A. let him spend a meaningful summerB. encourage him to do more walkingC. help cure him of his reading problemD. make him learn more about weapons2. The book caught the author's eye because .A. it reminded him of his own dogB. he found its title easy to understandC. it contained pretty pictures of animalsD. he liked children's stories very much3. Which one could be the best title of the passage?A. Mum's Strict Order.B. My Passion forReading.C. Reunion with My Beagle.D. The Charm of a Book.BLight pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial light at night — in combination with habitat loss, chemical pollution.invasive (入侵的) species, and climate change — is driving insect declines, " the scientists concluded after assessing more than 150 studies.Insect population collapses have been reported around the world, and the first global scientific review published in February,said widespread declines threatened to cause a "catastrophic collapse of nature's ecosystems".There are thought to be millions of insect species, most still unknown to science, and about half are active at night. Those active in the day may also be disturbed by light at night when they are at rest.The most familiar impact of light pollution is moths (飞蛾) flapping around a bulb, mistaking it for the moon. Some insects use the polarisation of light to find the water they need to breed, as light waves line up after reflecting from a smooth surface. But artificial light can scupper (使泡汤) this. Insects areimportant prey (猎物) for many species, but light pollution can tip the balance in favour of the predator if it traps insects around lights. Such increases in predation risk were likely to cause the rapid extinction of affected species, the researchers said.The researchers said most human-caused threats to insects have analogues in nature, such as climate change and invasive species. But light pollution is particularly hard for insects to deal with.However, unlike other drivers of decline, light pollution is ly easy to prevent. Simply turning off lights that are not needed is the most obvious action, he said, while making lights motion-activated also cuts light pollution. Shading lights so only the area needed is lit up is important. It is the same with avoiding blue-white lights, which interfere with daily rhythms. LED lights also offer hope as they can be easily tuned to avoid harmful colours and flicker rates.4. What is discussed in the passage?A. Causes of declining insect populations.B. Consequences of insect population collapses.C. Light pollution: the key bringer of insect declines.D. Insect declines: the driver of the collapsed ecosystem.5. What is the 5th paragraph mainly about?A. How light travels in space.B. How light helps insects find food.C. How the food chain is interrelated.D. How light pollution affects insects.6. What does the underlined word"analogues"in Paragraph 6probably mean?A. Selective things.B. Similar things.C. Variations.D. Limitations.7. What is the purpose of the last paragraph?A. To offer solutions.B. To give examples.C. To make comparisons.D. To present arguments.CI am a part of the Windward Robotics team known as the Omnicats, one of the many clubs offered at my school. My eight teammates and I started out by watching the robotics qualifiers and finals of Chinese teams. We used these robotics videos for inspiration and drew up mind maps of what our team wanted to do.We meet every day for two hours after school in order to build our robots. Typically, adultsoverseewhat students are building, but my school lets teens take control. It leaves room for more errors, but we're prouder of our final product.Before our first real match, a practice was offered at the actual site. My sub-team had been further along than other teams but quickly fell behind. When we arrived on that big day, I immediately felt my teammates' nervousness. Our first match was in three minutes. All of us glanced around at each other since we were not prepared at all. Our robot was still sitting in a box. Two of our teammates rushed to take the robot for an official examination as the rest of us discussed our strategy (策略).Our team captain explained that we all should try driving the robot now, while it was early in the season. She gave me the remote. I had only driven for a limited amount of time in practice so I was extremely nervous. Our autonomous code (自动代码) beganto run almost immediately after our short discussion. Despite all the drama, we ended up winning the match.Not too bad for the first match! I was so proud. I did not enjoy the pressure of driving but liked building the robot behind the scenes instead.We have transferred to a different type of robotics at the end of the semester, which involves the whole team designing one giant robot with large tools. I am a part of the electrical team now, so I make sure the motherboard (母板) can supply the robot's energy needs. We have all enjoyed the rest of the season and learned that robotics it never dull!8. What does the underlined word in paragraph 2 probably mean?A. InspectB. AdmireC. OverlookD. Assume9. Why did her teammatesfed so nervous before first match?A. Because it was really too difficult for them.B. Because they didn't prepare for it at all.C. Because they didn't know what the match would be like.D. Because they didn't make full preparations before the match.10. How did the author feel about their first robotics match?A. It was tiring but exciting.B. It was stressful but wonderful.C. It was terrible but powerful.D. It was boring but professional11. What is the best title for the text?A. A Girl Who Loves RobotsB. My First Robotics MatchC. Teamwork for RobotsD. Robotics Is Never DullDWhen Rich Jean wanted to help his daughter, Abigail, learn to read, he took her to the library near their home in Brooklyn, N. Y. That's where they met Hasina Islam, who Jean says arose her interest in reading and the library.“You see what you started? You see that spark that you put in this child?” Jean told Hasina Islam at aStoryCorpsconversation in 2016. At the time, Abigail was 7 and Islam was 27. Their friendship began when Abigail was 3. Through the years, Islam has offered book suggestions that Abigail has read with great enthusiasm. “What's cool is that Hasina has recommended a lot of books that I, at the time, thought might be a little too advanced for you," Jean told Abigail. “Like Charlie and the Chocolate Factory." Abigail said.Islam's own love of the library was sparked when she was in the third grade. She lived near the main branch of the Queens Public Library in New York City, and she went there to research Henry Hudson, an English explorer, for a school project."The librarian made me feel so special. She remembered my name, and my favorite thing was that she gaveme book recommendations," she said." When I was graduating from college, I thought about how I was going to make a difference in the world. And I remembered my librarian，and I remembered that feeling that she gave me every single time I went to the library. ”12. When might Abigail and Hasina Islam first meet?A. In 2012.B. In 2016.C.

The study was led by professor of psychology Jean M. Twenge at San Diego State University (SDSU).To research this link, Twenge, along with colleagues Gabrielle Martin at SDSU and W. Keith Campbell at the University of Georgia, dealt with data from the Monitoring the Future (MtF) study, a nationally representative survey of more than a million U. S. 8th-, 10th-, and 12th-graders. The survey asked students questions about how often they spent time on their Phones, tablets and computers, as well as questions about their face-to-face social interactions and their overall happiness.On average found that teens who spent more time in front of screen devices — playing computer games, using social media, texting and video chatting — were less happy than those who invested more time in non-screen activities like sports, reading newspapers and magazines, and face-to-face social interactions."The key to digital media use and happiness is limited use," Twenge said. "Aim to spend no more than two hours a day on digital media, and try to increase the amount of time you spend seeing friends face-to-face and exercising — two activities reliably linked to greater happiness."Looking at historical trends from the same age groups since the 1990s, it's easy to find that the increase of screen devices over time happened at the same time as a general drop-off in reported happiness inU. S.teens. Specifically, young peopled life satisfaction and happiness declined sharply after 2012. That's the year when the percentage of Americans who owned a smartphone rose above 50 percent. By far the largest change in teens' lives between 2012 and 2016 was the increase in the amount of time they spent on digital media, and the following decline in in-person social activities and sleep.4. Which method did Twenge's team use for the study?A. Calculating students' happiness.B. Asking students certain questions.C. Analyzing data from a survey.D. Doing experiments on screen time.5. How does the author develop the finding of the study in paragraph 3?A. By making a comparison.B. By giving an example.C. By making an argument.D. By introducing a concept.6. What is the purpose of the last paragraph?A. To draw a conclusion from the study.B. To offer some advice to the readers.C. To prove social activities' importance.D. To support the researchers' finding.7. Which of the following can be the best title for the text?A. Quitting Phones Equals HappinessB. Screen Time Should Be BannedC. Teens' Lives Have Changed SharplyD. Screen-addicted Teens Are UnhappierCFaming is a tradition among many in South Dakota, one that is not always easy to keep in the family. But one family has survived four generations and hopes to continue long into the future. The year was 1933 when Ed VanderWal's father first stepped onto the farm. Now 80 years later, Ed carries the passion(热情) his father gave him for farming every daywhile working the fields on the family farm in Volga.“Well, I was in the first grade when my dad moved here to this farm and I grew up on the farm. And that's what I was interested in doing more,” Ed said. But that love of working the land didn't stop with Ed. He's passed it down to his six sons. Some of them run farms of their own now, but two of them, Scott and David, still work side by side with their dad every day.Some people might worry that working sun up to sun down with family seven days a week would lead to afew family spats(争吵). But for the VanderWals, the constant time together works just fine.“When families work together on a farm, it's a challenge at times getting along. Everyone has to pull their weight and do their share. And that, of course, transfers from one generation to the next,” Scott said.And while they all get along like any family, with good days and bad, it's tradition that keeps each generation teaching the next.“But we taught them to work with animals at a young age, like most farmers do. So it's nice to be able to pass that tradition onto the next generation,” Scott said.The youngest generation of the VanderWals, Ed's three grandsons and a granddaughter, all started learning farming techniques at a young age.8. Why did Ed VanderWal devote himself to the farm?A. Because he grew up on the farm.B. Because he was affected by his father.C Because he could do nothing but work on the farm.D. Because he wanted to set a good example for his sons.9. What can we know from Paragraph 2?A. Managing a farm is a real challenge.B. Ed has divided his farms into six parts.C. Ed taught his sons how to work on farms.D. Scott and David own their own farms now.10. What can be inferred from the passage?A. The VariderWals have strict family rules.B. Ed's tradition has great effect on the local.C. Ed's grandchildren will drop out of school.D. Ed's farms have no lack of successors (继承者).11. What's the best title of the passage?A. A Faming Family.B. A Successful Farmer.C. The Agricultural 'Tradition.D. The Agricultural Generation.DA single toy catches a child's attention for a limited period of time, but a box of items that allows a child to build their own toys will catch their imagination for years to come.

She explained the entire process should be left to kids’ creativity, reminding teachers and all grown-ups that child-led play was an excellent way for children to develop lifelong skills.Toyi's creators are now considering distributing the kits to as many children as possible around the world through different international NGOs. Atmaca notes that for each Toyi kit sold out, they will also donate one kit toa disadvantaged child through different partnerships around the world.12. Why did Atmaca design Toyi at first?A. To win the famous IF Design Award.B. To help poor kids make their own toys.C. To protect the environment in Istanbul.D. To recycle all the waste in the dustbin.13. Which is probably the product made with the toy kit of Toyi?A. A new picture of a young boy.B. A computer with high technology.C. A treasure container from a dustbin:D. A six-armed “robot” from a water bottle.14. How do the toy kits help improve the children's ability?A. It provides the kids various types of toys.B. It offers space for the kids’ creative minds.C. It changes the poor kids' living conditions.D. It teaches the kids to share joys with others.15. What is the new target for Atmaca and her partners?A. Donating toykits to more poor children.B. Selling toy kits to every kid in the world.C. Designing new toy kits for kids and adults.D. Doing further research on the kids' demands.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
