2019-2020学年西藏自治区拉萨中学高三英语第三次联考试题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AIt’s a tempting habit for them to look at their smartphone rather than make eye contact with someone. There is so much to look at: photographs, social media feeds, messages and emails. No wonder they are glued to their screens. But is it good for them?There have been many claims about the damage looking at screens does to our eyesight. Some people feared staring at a small bright box could make us short-sighted. This is a particular concern for children and young people, who spend a higher percentage of time using electronic devices. BBC reporter, Rory Jones, says, “There is enough evidence that no matter how long teenagers are spending looking at screens, they come across information about issues such as anorexia and self-harm that could prove damaging to their mental health.”But a new study says time in front of computers and phones might not be as bad for young people as many think. Research by the Oxford Internet Institute examined data from more than 17,000 teenagers in theUK,Irelandand theUnited States. Their study concluded that most links between life satisfaction and social media use were tiny, accounting for less than 1% of a teenager’s wellbeing. Professor Przybylski, director of research, said, “99.75% of a person’s life satisfaction has nothing to do with their use of social media.” The research found that family, friends and school life all had a greater impact on wellbeing.So, does this mean young people can spend longer looking at social media? TheOxfordresearchers are confident about its findings and that any connection between screen time and mental health is very small. Dr. Max Davie, officer for health improvement at theRoyalCollege, calls the study a “small first step”, but he says there are other issues to explore, such as screen time’s interference(干预) with other important activities like sleep, exercise and time with family or friends. Perhaps for now, the “right” amount of screen time is only a matter of personal judgement.1. What is people’s common belief concerning screen time?A. Looking at screens does harm to young people.B. Screen time provides a chance for teenagers to learn.C. Most teenagers get near-sighted due to looking at screens.D. A small amount of time online does little harm to teenagers.2. What can we learn from the new study by the Oxford Internet Institute?A. Screen time has a great influence on people’s daily activities.B. The right amount of the screen time is related to its content.C. There is a close link between social media and self-satisfaction.D. Social bonds play a more significant role in people’s wellbeing than social media.3. Where is the passage most probably taken from?A. A science fiction.B. A science magazine.C. A research paper.D. An economics book.BAfter finishing his dinner, Lin Xu opened a WeChat mini-program called "Clear Plate" on his phone and took picture of the empty plates. He was then awarded 157 credit points after the image was uploaded and recognized by artificial intelligence.“Users of the app can use their credit to buy gifts, such as books and cellphones to purchase charity meals donated to children in poor rural areas,” Lin said.A nationwide "Clear Your Plate" campaign is gaining steam online. Efforts to stop food waste and promote thrift are also being made by restaurants that have been urged to create an environment in which consumers are reminded not to waste food. They are also encouraged to offer different portion sizes so that customers can have more choices.The “Clear Plate” mini-program has become popular among young Chinese and currently has nearly 1 million users.Liu Jichen, founder of the startup that developed the app, said that the idea popped up at a dinner in 2017, when Liu found that a restaurant would give diners who polished off their food a card and offer small gifts after a certain number of cards had been collected.“Such an idea can be realized online,” Liu said. He formed a team to work on the project.Yet it was quite challenge for the AI system to identify whether the uploaded photos showed empty plates.To make the AI system smarter, Liu and his team, assisted by more than 1,000 others, spent half a year collecting over 100, 000 samples in canteens and restaurants across the country and used the data to train neural network. Dozens of enterprises, institutions and restaurants have contacted the startup to cooperate on the project.Through the visualized mini-program, people can clearly see the good results of saving food, which will effectively reduce waste, he noted. "We hope our efforts can start a new trend among the younger generation, encouraging them to carry out the virtue of cherishing food and developing the habit of thrift, " Liu said4. What is the main function of the APP "Clear Plate?A. Awarding credit points.B. Giving charity meals.C. Showing the empty plates.D. Encouraging saving food.5. How is the "Clear Your Plate" campaign carried out?A. Customers wasting food are punished.B. People join in it on mini-program.C. Restaurants limit customers' choices.D. People are encouraged to buy gifts.6. What was the most difficult when the app was created?A. Getting other people to cooperate with the team.B. Collecting samples in canteens and restaurants.C. Ensuring the app to recognize empty plates.D. Finding people to fund the app.7. What is the purpose of the writing?A. To introduce an app.B. To promote saving food.C. To praise a startup founder.D. To raise fund for poor children.CFor fishermen and sailors in the seaside town of Shangpan in Linhai, Zhejiang province, where recently 12 stranded（搁浅的）whales were found, it is not unusual to spot whales or dolphins in the sea — they would always call them haizi, or “son of the ocean”. And if the local fishermen spot such intelligent sea creatures in need, they will save them from danger without hesitation.In the recent rescue of melon-headed whales, they tried their best to help as a 37-second video of a young man sleeping in the water holding a whale soon went viral online, with netizens applauding his constant efforts and caring heart in trying to keep the whale alive. “The melon-headed whale knew I was trying to save it and would be more cooperative and wouldn’t move.” said Lu Wenhui, a 21-year-old diver from Hangzhou Changqiao Polar Ocean Park, who held up the whale’s head so it could breathe easily. Lu had been staying in the water for 10 hours by 4 a.m. Wednesday after coming for the rescue work on Tuesday, when the stranded whales were first spotted.“Whales are mammals and need to breathe in air — that’s why I had to hold its head, to ensure it could breathe smoothly the whole time,” Lu said. The stranded whales, after the struggling of being transported, wereworn out when they arrived at the fish farm and might have drowned if they were left unattended.The reason why the whales were stranded is still not clear. And these stranded whales were returned to the ocean because they are not adapted to artificial breeding environments on land.8. What do local fishermen usually do after finding haizi in danger?A. Ignore them.B. Feed them.C. Transport them.D. Protect them.9. Why does the author describe Lu’s rescue work?A. To introduce the whales in detail.B. To voice his views on the diver.C. To praise the efforts made by rescuers.D. To explain the value of the whales.10. What can we say about the melon-headed whales according to the text?A. They are rarely seen by locals.B. They are used to breathing in the sea.C. They aren’t suited to artificial surroundings.D. They are fond of swimming near the seaside.11. Which of the following can be the best title for the text?A. Melon-headed Whales Were StrandedB. Rescuers Went All out to Help WhalesC. Fishermen Transported Stranded WhalesD. Witnesses Voiced Opinions on Rescue WorkDAbout a month after I joined Facebook, I got a call from Lori Goler, a highly regarded senior director of marketing at eBay. She made it clear this was a business call. “I want to apply to work with you at Facebook,” she said. “Instead of recommending myself, I want to ask you: What is your biggest problem, and how can I solve it?”My jaw hit the floor. I had hired thousands of people over the previous decade and no one had ever said anything remotely like that. People usually focus on finding the right role for themselves, with the implication that their skills will help the company. Lori put Facebook’s needs front and center. It was a killer approach. I responded, “Recruiting is my biggest problem. And, yes, you can solve it.”Lori never dreamed she would work in recruiting, but she jumped in. She even agreed to trade earnings for acquiring new skills in a new field. Lori did a great job running recruiting and within months was promoted to her current job, leading People@Facebook.The most common metaphor for careers is a ladder, but this concept no longer applies to most workers. As of 2010, the average American had eleven jobs from the ages of eighteen to forty-six alone. Lori often quotes Pattie Sellers, who came up with a much better metaphor: “Careers are a jungle gym, not a ladder.”As Lori describes it, there’s only one way to get to the top of a ladder, but there are many ways to get to the top of a jungle gym. The jungle gym model benefits everyone, but especially women who might be starting careers, switching careers, getting blocked by external barriers, or reentering the workforce after taking time off. The ability to create a unique path with occasional dips, detours (弯路), and even dead ends presents great views of many people, not just those at the top. On a ladder, most climbers are stuck staring at the butt of the person above.12. Why did Lori make the call?A. She helped Facebook to solve the biggest problem.B. She wanted to make a business deal with Facebook.C. She tried to ask for a pay rise in Facebook.D. She wanted to become an employee in Facebook.13. What impressed “I” by Lori?A. Lori was good at running recruiting.B. Lori attached great importance to Facebook’s needs.C. Lori jumped in Facebook with no adequate experience.D. Lori was skilled in marketing at eBay.14. What can we infer from the passage?A. Now all people don’t tend to climb the ladder.B. None on the ladder can enjoy the great views.C. Jungle gyms offer limited exploration for employees.D. A pregnant woman, jobless, benefits little from the jungle gyms.15. What is the best title of the passage?A. It’s a Jungle Gym, Not a Ladder.B. Facebook’s Biggest Problem.C. Applying for a Job in Facebook.D. A Jungle Gym is Better than a Ladder.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。

Children 10 years and under are not permitted on Blue Mountains Tours.D. All the tours are charged and designed only for adventures.2.If you have a chance to go to Finland, you will probably be surprised to find how “foolish” the Finnish people are.Take the taxi drivers for example. Taxis in Finland are mostly high-class Benz with a fare of two US dollars a kilometer. You can go anywhere in one ，tell the driver to drop you at any place ，say that you have some business to attend to, and then walk off without paying your fare. The driver would not show the least signs of anxiety.The dining rooms in all big hotels not only serve their guests, but also serve outside diners. Hotel guests have their meals free, so they naturally go to the free dining rooms to have their meals. The most they would do to show their good faith is to wave their registration cards to the waiter. With such a loose check, you can easily use any old registration card to take a couple of friends to dine free of charge.The Finnish workers are paid by the hour. They are very much on their own as soon as they have agreed with the boss at the rate. From then on they just say how many hours they have worked and they will be paid accordingly.With so many loopholes(漏洞) in everyday life, surely Finland must be a heaven to those who love to take “petty advantages”. But the strange thing is that all the taxi passengers would always come back to pay their fares after they have attended to their business and that not a single outsider has ever been found in the free hotel dining rooms. And workers always give an honest account of the exact hours they put in. As the Finns always act on good faith in everything they do, living in such a society has turned everyone into a real “gentleman”． 1．The underlined words in Paragraph 5 means to “________”． A. be ready to help others B. make good use of one's friends C. be a little ahead of others D. gain something at other's expense 2．Which of the following is NOT true according to the passage?A. While taking a taxi in Finland ，you can get off without first paying your fare.B. In a big hotel in Finland, you can enjoy free meals if you're living in the hotel.C. The bosses in Finland pay the employees according to the registration of their working hours.D. The workers are always honest with their working hours. 3．We can learn from the passage that ________. A. the Finnish society is of very high moral(道德的)level B. there are many loopholes in everyday life in Finland C. in Finland, most taxi drivers will not charge you anythingD. everyone in Finland is like a gentleman, for they have faith in themselves 4．Which of the following is the best title of the passage? A. Life in Finland B. A Society with “Foolish” People。

This would mean that she always felt that she was protected and would always have money if she really needed it.When I was married in 1970 my husband who had heard this story, obtained a 1937 crown coin for me and I have always kept it in my wallet, and I have always had enough for my needs.A friend recently fell on hard times, partly through external (外部的）circumstances and partly through poor planning. Friends and I have loaned her money, paid her bills, given her food, and even tried to teach her budget techniques, but none of them has been a solution. She has just slipped deeper and deeper into financial trouble and depression.Last week she looked pale and unwell, very depressed and hopeless, very sad for a friend to see and I then thought about how the crown coin, a physical reminder of another’s care and love had protected me, so I went to the bank for a $ 100 dollar-bill.I told my friend the story and asked her to keep the $ 100 in the back of her wallet. It turned out that she didn’t havea wallet, so she put the money in a little pencil case where she kept her coins. She immediately felt better—“I feel rich, and thank you for being a good friend,” she said, and we were both a bit teary.I went home and remembered a little wallet I had that I’d never used, and thought, “I’ll give that to my friend.” I opened it, and inside, found $ 100.25. What di d the 1937 crown coin from the author’s father mean to her mother?A. His concern for her.B. His pity and protection for her.C. His care and love for her.D. His pride and respect for her.26. Where did the author’s friend keep the $ 100 dollar-bill?A. In the back of her wallet.B. In a little pencil case.C. In the pocket of her raincoat.D. In the layer of her suitcase.27. What can be inferred from the last paragraph?A. The author became rich all of a sudden.B. The author’s friend would receive a wa llet as a gift.C. The author’s friend was not touched by her story.D. The author felt uncomfortable when receiving the bill.28. What can be the best title for the text?A. A crown coinB. The help to a friendC. A hard lifeD. A gift from my fatherCIn China, chain restaurants — especially the big multinational ones — are cool. Going to Starbucks, for example, is a status symbol. It not only says, “I’m rich enough to buy this overpriced coffee,” but also, “I’m cosmopolitan （见多识广的）enough to be part of globalization.”Where I come from in the UK，however，chains are neither fashionable nor gourmet（美食的）. Chains are where you go on New Year’s Day when nowhere else is open，or when you are 5 years old and your parents can’t stand hearing “I’m huuungry!” any lon ger. In my own case (with regards to McDonald’s), a chain is where you are taken on your first “date”. Even at the age of 13, I knew to give the guy the “let’s just be friends” phone call the next day.In the UK, independent cafes and restaurants are making a comeback on the fashion scene. Nowadays, a Londoner who says “let’s meet for a coffee at Monmouth” (an independent café) is much cooler than one who says “let’s go to Starbucks”. Even if Monmouth’s coffee is a little more expensive, there’s a satisfaction in knowing your pounds aren’t going straight to the big corporations.Of course, there are chain stores all over the UK; you can’t go five minutes without spotting a Costa Coffee. But numbers do not add up to good taste.I do, however, have a confession (坦白). After moving to China I had moments when all the rice and Kung Pao Chicken became too much. I, too, have retreated to McDonald’s.29. Many Chinese people like to go to multinational chain restaurants because ______.A. the restaurants give customers a taste of foreign cultureB. the restaurants offer different food and drinks from other restaurantsC. they believe that eating there will show their wealth and social statusD. these restaurants are perfect places for a romantic date30. Which of the following statements is TRUE?A. The author has grown tired of Chinese food.B. Branches of Monmouth’s cafe can be found all over the UK.C. Most independent stores are closed on New Year’s Day in the UK.D. It is cool in the UK to take your first date to a chain restaurant.31. We can infer from the article that ______.A. the author doesn’t like food from Pizza HutB. the author doesn’t like to follow fashion trendsC. many Britons think that numbers mean poor qualityD. many Britons don’t like big co rporationsDDarwin noted that some human emotional expressions might have started as part of a physiological function: for example, exposing the teeth to bite food. The function, however, took on meaning and became a form of communication which signals anger.The same may be true for the animals. Baby monkeys cry for attention. They also cry to signal to an adult that they want to be carried.“Chimpanzees do make upset voice when they are being weaned (断奶) by their mothers or have lost their mothers or ano ther individual,” says Anne Pusey, a professor at the University of Minnesota. “They whimper (呜咽) and cry and scream. When we hear these calls, the emotion involved seems obvious. However, they do not weep in the sense of producing tears. I have seen an adolescent male whimpering when he lost sight of his older brother with whom he had been traveling.”Babies of many mammalian species, including rats, cry. Moreover, when a baby rat cries, often his mother brings the fallen pup back into the nest. This is probably a straightforward communication, as it is with humans. However, psychologists at the University of Iowa aren’t convinced.The Iowan researchers can cause the same crying sounds by producing large decreases and then increases in blood flow. The blood flow also goes down when baby rats get cold. Thus, they conclude baby rats cry in the same way that we sneeze. Of course the rat baby could be crying because he’s cold and wants his mother to know.“All young mammals make cries when separated from their mother,” says Jaak Panksepp, a psychologist at Bowling Green State University. “If you’re willing to call this crying, then certainly other animals show this emotional response.” he says, “Some of us take seriously that animals do have emotions.”32. Accord ing to the first paragraph, what kind of emotion does “exposing the teeth” express?A. Disappointment.B. Excitement.C. Anger.D. Happiness.33. Which is one probable reason why young chimpanzees might be crying?A. They meet their brother.B. They have nothing to eat.C. They are being breast-fed.D. They are parted from their mother.34. Under what circumstance will baby rats cry just like humans’ sneeze?A. Their blood flow is decreased.B. They feel cold and long for affection.C. Their blood flow is increased.D. Their mother brings them back home.35. Where is the passage most likely taken from?A. An animal journal.B. A physiology book.C. A health magazine.D. A cultural newspaper.第二节七选五（共5小题；每小题2分，共10分）Apologizing can be very difficult. It takes maturity to put aside your pride and own up to your faults. 36. , it’s easy to make mistakes.37. . For the other person to heal, address the expression and acknowledge your actions were out of line. Takea careful look at the part you played in the fault. While you could offer some context or explanation for how things went wrong, you shouldn’t let that negate(否认) your apology.If you aren’t coming across as sincere, you are just not going to win in the apology department. 38. , and can focus on your tone and sincerity when it comes time to deliver them. In the long run, not being genuine just creates more distrust instead of repairing the damage.Waiting too long to apologize can make a bad situation worse. Do it sooner rather than later. However, apologizing too quickly can also be problematic. Sometimes people need a minute to cool off, and if someone’s t rying to hound(催促) them to give them an apology, it’s not going to work. If time has passed, you can still attempt to right a wrong.39. .Saying “I’m sorry, but…”is one of the worst ways to say you’re sorry. When you use the word “but”, it negates or cancels everything that goes before it. 40. . Even if your intentions were good, you still have to own up(老实承认) to the harm you caused.A. And when you do express an apologyB. It’s important to apologize face to face if possibleC. The old saying holds true — better late than neverD. Although it’s hard to generalize when it comes to apology timingE. Practice your apology beforehand so that you’re comfortable with the wordsF. Apologizing is about owning up to your mistakes, not making excuses for themG.

But the 41 would no doubt be greater if you were living on the streets with little food and money. All of this makes the actions of the homeless Tom Smith 42 more remarkable.After spotting a 43 on the front seat inside a parked car with its window down, he stood guard in the rain for about two hours waiting for the 44 to return.After hours in the cold and wet, he 45 inside and pulled the wallet out hoping to find some ID so he could contact（联系）the driver, only to 46 it contained £400 in notes, with another £50 in spare change beside it.He then took the wallet to a nearby police station after 47 a note behind to let the owner know it was safe. When the car’s owner John Anderson a nd his colleague Carol Lawrence returned to the car — which was itself worth £35, 000 — in Glasgow city centre, they were 48 to find two policemen standing next to it. The policemen told them what Mr. Smith did and that the wallet was 49 .The pair were later able to thank Mr. Smith for his 50 .Mr. Anderson said: “I couldn’t believe that the guy never took a penny. To think he is sleeping on the streets tonight 51 he could have stolen the money and paid for a place to stay in. This guy has nothing and 52 he didn’t take the wallet for himself; he thought about others 53 . It’s unbelievable. It just proves there are 54 guys out there.”Mr. Smith’s act 55 much of the public’s attention. He also won praise from social media users after Mr. Anderson 56 about the act of kindness on Facebook.Now Mr. Anderson has set up an online campaign to 57 money for Mr. Smith and other homeless people in the area, which by yesterday had received £8,000. “I think the faith that everyone has shown ____58_ him has touched him. People have been approaching him in the street; he’s had job 59__ and all sorts,” Mr. Anderson commented.For Mr. Smith, this is a possible life-changing 60 .
