（16分）重返时间的河流格非（1）在法国，或者说在欧洲、在整个欧洲文学变革的历史当中，有一个特别重要的、承上启下的人物——福楼拜。

翻开他的《包法利夫人》，就会看到奇怪．．①的一段文字。

他描写这个主人公包法利，戴了一顶奇怪．．②的帽子。

一个作家在小说里面写一个人物戴了一顶帽子，一般三言两语就可以。

可是福楼拜用了差不多有十行。

描述这个帽子的颜色、形状，它的帽沿，帽子内部使用鲸鱼骨支撑开，它还有带子，带子上还有小坠……写得极其复杂。

小说刚开始，就用这么长的篇幅，来写一顶帽子，真有点过分。

2019-2020学年上海市建平中学高三英语上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AChildren under the age of 18 will be allowed up to three hours per week to play video games, according to a notice issued by China's National Press and Publication Administration. Online game companies are required to provide services to minors — from8 to 9 p. m. on Fridays, Saturdays, Sundays and legal holidays — as a way to safeguard their physical and mental health. Children are playing more and more online games these days. Is it time to limit their online gaming time? What role do parents have? Readers share their opinions.RizlaredOnline games are addictive, but if children are taught how to manage in a sensible and responsible manner then it is no longer a threat(威胁).To achieve this, parents need to set examples for not being glued to their phones. Teaching is and always will be the best solution to such problems.AndrewGood policy. By limiting time spent on online games, kids can spend time doing more useful things to develop their potential. They can go outside and run, jump and swim instead of sitting on a couch at home and playing with a smart phone.AdamIt is often seen that parents argue with children over cellphones. Most parents can hardly set and enforce the time limit for its daily usage. Some forcibly take away their cellphones, but it will ruin trust and relationship. Even worse, it will make their kids hate them.PinkExcessive(过度的）gaming is purely a waste of time and energy for minors and has a negative effect on both physical and mental health. The gaming industry should not put profit- flaking interests as its priority (优先事项) . They should act in a socially responsible way toprovide an environment for children to ensure their well-being and development.LaurenThere would be a loophole(漏洞). Children could use their parents’ or other adults’ IDs to avoid real-name registration, thus making it impossible to put this policy in effect. Parents ly need to strengthen guidance andsupervision to keep their children from gaming addiction.1. What should kids do according to Andrew?A. Play online games.B. Play with a smart phone.C. Study all the time.D. Go in for outside activities.2. What does Pink advise the gaming industry to do?A. Pay attention to its profit.B. Focus on kids’ health.C. Be responsible for kids’ surroundings.D. Persuade kids lo play more games.3. What role do parents have according to the passage?A. They keep hold of their phones.B. They set examples for their kids.C. They limit their kids’ time.D. They blame kids for addiction.BLast year, 138,000San Franciscoresidents used Airbnb, a popular app designed to connect home renters and travelers. It’s a striking number for a city with a population of about 850,000, and it was enough for Airbnb to win a major victory in local elections, asSan Franciscovoters struck down a debatable rule that would have placed time restrictions and other regulations on short-term rental services.The company fiercely opposed the measure, Proposition F, with a nearly $10 million advertising campaign. It also contacted its San Franciscan users with messages urging them to vote against Proposition F.Most people think of Airbnb as a kind of couch-surfing app. The service works for one-night stays on road trips and longer stays in cities, and it often has more competitive pricing than hotels. It’s a textbook example of the “sharing economy”, but not everyone is a fan.The app has had unintended consequences inSan Francisco. As the San Francisco Chronicle reported last year, a significant amount of renting on Airbnb is not in line with the company’s image: middle-class families putting up a spare room to help make ends meet. Some users have taken advantage of the service, using it to turn their multiple properties into vacation rentals or even full-time rentals. Backers of Proposition F argued that this trend takes spaces off the conventional, better-regulated housing market and contributes to rising costs.“The fact is, widespread abuse of short-term rentals is taking much needed housing off the market and harming our neighborhoods,” said ShareBetter SF, a group that supported Proposition F. Hotel unions have protested the company’s practices inSan Franciscoand other cities, saying that it creates an illegal hotel system.San Franciscois in the middle of a long-term, deeply rooted housing crisis that has seen the cost of living explode. Actually, explode is a generous term. The average monthly rent for an apartment is around $4, 000.Located on a narrow outcropping of land overlooking the bay,San Franciscosimply doesn’t have enough space to accommodate the massive inflow of young, high-salaried tech employees flocking toSilicon Valley.As the Los Angeles Times reported, someSan Franciscoresidents supported the measure simply because it seemed like a way to check a big corporation. Opponents of Proposition F countered that the housing crisis runs much deeper, and that passing the rule would have discouraged a popular service while doing little to solve the city’s existing problems.4. The intention of Proposition F is to ________.A. place time limits in local election.B. set limits on short-term rental.C. strike down a controversial rule.D. urge users to vote against Airbnb.5. What is the negative consequence of Airbnb onSan Francisco?A. It shrinks the living space of middle-class families.B. Users are taken advantage of by the service financially.C. It makes the house market more competitive.D. It indirectly leads to high house rental price.6. The housing crisis inSan Franciscoresults from ________.A. explosion of the living costB. its geographic characteristicsC. generosity of local enterprisesD. inflow of migrant population7. Theauthor’s attitude toward Proposition F is ________.A. objectiveB. supportiveC. negativeD. indifferentCDolores Huerta has worked hard most of her life to help other people. She has helped change things so that others can have a better life.Dolores grew up in California. She was a good student and liked school. After she finished high school, she went to college and studied to be a teacher. After college, she became a teacher. Dolores noticed that many of her students were not getting enough food to eat. Some of them wore very old clothes. Dolores wondered how she could help them.Dolores liked teaching but she decided to quit her job so that she could spend more time helping her students and their families. One thing she wanted to do was to get more pay for their parents, farm workers. Thus they could buy their children what they needed.Dolores knew that many farm workers moved often from one place to another to help pick different kinds of fruits and vegetables, like grapes and tomatoes. She began talking and writing about these workers. Even people who lived far from California read what Dolores wrote. Getting higher pay for the farm workers was not easy. Dolores worked hard to make sure that farm workers got fair pay for their work. She knew that nothing would change unless new laws were made to help the workers. Through all her hard work, new laws were passed that gave farm workers fair pay.Dolores Huerta has worked for more than 30 years in many different ways to make life better for working people. She has shown how much one person can change things.8. What did Dolores find about her students?A. They worked hard to make a living.B. They lived far away from schools.C. They had little time to play.D. They were hungry sometimes.9. Why did Dolores stop teaching?A. She wished to be a lawyer.B. She moved to another place.C. She wanted to help her students more.D. She got little money by teaching.10. Thanks to Dolores’ great effort, the farm workers ________.A. got better jobsB. got fair payC. had more time offD. had a settled way of life11. What is the main idea of the passage?A. One person can make big changes.B. One can change their jobs often.C. One person can work hard for others.D. One can make life better by themselves.DIn the summer of 2016, I gave a talk at a small conference in northernVirginia. I began by admitting that I’d never had a social-media account; I then outlined arguments for why other peopleshould consider removing social media from their lives. The event organizers uploaded the video of my talk to YouTube. Then it was shared repeatedly on Facebook and Instagram and, eventually, viewed more than five million times. I was both pleased and annoyed by the fact that my anti-social-media talk had found such a large audience on social media.I think of this event as typical of the love-hate relationships many of us have with Facebook, Instagram, and other social-media platforms. On the one hand, we’ve grown cautious about the so-called attention economy,which, in the name of corporate(公司的) profits, destroys social life gradually and offends privacy. But we also benefit from social media and hesitate to break away from it completely. Not long ago, Imet a partner at a large law firm in Washington, D.C., who told me that she keeps Instagram on her phone because she misses her kids when she travels; looking through pictures of them makes her feel better.In recent months, some of the biggest social-media companies, Facebook and Twitter, in particular, have promised various reforms. In March, Mark Zuckerberg announced a plan to move his platform toward private communication protected by end-to-end encryption(端对端加密); later that month, he put forward the establishment of a third-party group to set standards for acceptable content.All of these approaches assume that the reformation of social media will be a complex, lengthy, and gradual process. But not everyone sees it that way. Alongside these official responses, a loose collective of developers that calls itself the IndieWeb has been creating another alternative. They are developing their own social-media platforms, which they say will preserve what’s good about social media while getting rid of what’s bad. They hope to rebuild social media according to principles that are less corporate and more humane(人道的).12. Why did the author feel annoyed when his video was spread online?A. His video caused many arguments.B. His video was shared without his permission.C. His talk was opposed by a large amount of people.D. His video’s popularity on social media is against his talk.13. Why does the author mention the story of his partner in paragraph 2?A. To prove that social media has some benefits.B. To advise people to break away from social media.C. To tell the negative effects social media may produce.D. To describe people’s complicated relationships with social media.14. What is the purpose of the reform made by some social-media companies?A. To attract more users.B. To improve network environment.C. To make more profits.D. To provide more convenientservice.15. What does the IndieWeb intend to do?A. Develop new social-media platforms.B. Remove social media from people’s lives.C. Improve the existing social-media principles.D. Help social-media companies to make reformation.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。

No matter whether your idea of a hike is a leisure walk or climbing the highest mountain on Earth, we've got you covered. Below are four best hikes inthe world.Torres del Paine W CircuitLocation (位置): Patagonia. ChileDistance: 37 + milesTime: 5~6 daysBest time to go: October to JanuaryThe W Circuit is one of the most recommended hikes you'll find. Not only will you appreciate the diverse landscapes and striking granite pillars (花岗岩柱子), but you'll probably meet some new friends along the way.Grand Canyon Rim - to - Rim HikeLocation: Arizona, the United StatesDistance: 48 milesTime: 1~3 daysBest time to go: May to June, September to OctoberThere's no better way to experience one of the greatest wonders in the world. Located in one of the USA's most beautiful parks, the views are ly appealing. Just make sure you're prepared for the challenge.Trek to PetraLocation: JordanDistance: 47 milesTime: 5~ 6 daysBest time to go: October to AprilTake the road less traveled through the Kingdom of Jordan and experience one of the seven wonders of the world. Hike through canyons, gorges and ridges, and see tombs and temples along the way all while avoidingcrowds of tourists.Yosemite Grand TraverseLocation: California, the United StatesDistance: 60 milesTime: 6~7 daysBest time to go: July to SeptemberKnown for some of the best hiking in the world, Yosemite National Park is famous for its views and huge sequoia (红杉) trees. Praised byNational Geographic, the Yosemite Grand Traverse will take you through waterfalls and green mountaintops.1.Which of the following is the best time for the hike in Patagonia, Chile?A.AprilB.MayC.AugustD.December2.Where should you go for a less crowded hike?A.JordanB.Patagonia, ChileC.Arizona, the United StatesD.California, the United States3.What can you do along the Yosemite Grand Traverse?A.Plant sequoia treesB.Appreciate waterfallsC.Visit local templesD.Climb granite pillarsBA wife’s level of education positively influences both her own and her husband’s chances of having a long life, according to a new Swedish study.In the study, researchers from the Swedish Institute for Social Research inStockholmfound that a woman’s level of education had a stronger connection to the likelihood of her husband dying over education. What’s more, they discovered that a husband’s social class, based on his occupation, had a greater influence on his wife’s longevity(长寿) than her own class.“Women traditionally take more responsibility for the home than men do, and, as a result, women’s levels of education might be more important for determining lifestyles－for example, in terms of food choices－than those of men,” say Srs. Robert Erikson and Jenny Torssander of the Swedish Institute for Social Research inStockholm.The results show that a husband’s level of education does not influence his longevity, but that men with partners who had quit studying after school were 25 per cent more likely to die early than men living with women holding university degrees. In turn, those married to women with university degrees were 13 percent more likelyto die early than those whose wives had post-graduate qualifications.According to the researchers, a woman with a good education may not marry a man who drinks and smokes too much or who drives carelessly, and men with such habits may not prefer highly educated woman. Drs. Erikson and Torssander also suggest that better-educated women may be more aware of what healthy eating and good health care consist of.The findings suggest that education has a huge impact on how long and how well people live. It also reflects social factors, since educated individuals usually have better jobs, which allow them to afford healthier diets and lifestyles, as well as better health care.4. In this passage the author intends to ________.A. present the results of a studyB. encourage women to get higher educationC. analyze the relationship between education and lifeD. discuss why women usually live longer than men5. A woman with higher education is likely to ________.A. teach her children wellB. earn more money than her husbandC. marry a man without many bad habitsD. choose a husband with a higher degree than hers6. A wife’s education has more effect on a family than a husband’s because ________.A. women make more sacrifices to their families than men doB. most women have higher degrees than their husbandsC. most men marry women with higher degreesD. women have a leading role in the home life of most families7. We learn from the passage that ________.A. a man with a lot of education lives longer than one with littleB. educated wives tend to choose healthy lifestyles for their familiesC. highly-educated women don’t marry uneducated menD. a man’s longevity depends on not only his wife’s level of education but also his ownCMost people around the world are right-handed. This also seems to be true in history. In 1799, scientistsstudied works of art made at different times from 1,500 B.C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed that right-handedness has always been common through history. Today, only about 10% to 15% of the world’s population is left-handed.Why are there more right-handed people than left-handed ones? Scientists now know that a person’s two hands each have their own jobs. For most people, the left hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person’s hands and eyes work together, controls the left hand. The left-side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as among people in other jobs.No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born. However, this doesn’t happen to everyone, so scientists guess there must be another reason why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene(基因) for right-handedness, he / she may become either right-handed or left-handed according to the chance and the people they work or live with.Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don’t have to.8. After studying works of art made at different times in history, the scientists found _______.A. the art began from 1,500B.C.B. the works of art ended in the 1950sC. most people shown in the works of art are right-handedD. most people shown in the works of art are left-handed9. What is the left hand for most people used to do?A. It’s used to find or hold things.B. It’s used to work with things.C. It’s used to make a person’s eyes work together.D. It’s the centre for thinking and doing problems.10. According to the passage, which of the following is NOT true?A. No one really knows what makes a person become right-handed.B. Left-handedness is cleverer than right-handedness.C. Today children are not made to use their right hands only.D. Scientists think there must be some reason why people become left-handed.11. The best title for this passage is _______.A. Scientists’ New InventionsB. Left-handed PeopleC. Which HandD. Different Brains, Different HandsDThe modern Olympics, which appeared in ancient Greece as many as 3,000 years ago, have become the world’s most important sporting competition. From the 8th century B. C. to the 4th century A. D., the the ancient Olympics were held every four years in Olympia in honor of the god Zeus. The first modern Olympics took place in1896 inAthens, and featured 280 participants from 13 nations, competing in 43 events. Since 1994, the Summer and Winter Olympic Games have been held separately every two years. The 2020 Summer Olympics, delayed one year because of the COVID-19, was held in Japan in 2021.The ancient Olympics were held every four years between August 6 and September 19 during a festival honoring Zeus. The Games were named for their location (位置) at Olympia, a place near the western coast in southern Greece. Their influence was so great that ancient historians began to measure time by the Olympic Games held every four years.After the Roman Empire conquered (征服) Greece in the mid-2nd century B.C., the Games continued, but their standards and quality dropped. For example from 67 A. D., the Emperor Nero entered an Olympic horse race, announcing himself the winner even after he fell off hishorse during the event. In 393 A. D., Emperor TheodosiusⅠended the ancient Olympic tradition.It was another 1,500 years before the Games rose again, largely thanks to the efforts of Baron Pierre de Coubertin (1863-1937) of France. Working hard at the development of physical education, the young man became inspired by the idea of creating a modern Olympic Games after visiting the ancient Olympic building. In November 1892, at a meeting of the Union des Sports Athlétiques in Paris, Coubertin suggested the idea of making the Olympics an international athletic competition held every four years. Two years later, he got the approval (批准) he needed to found the International Olympic Committee ( IOC ), which would become the governing body of the modern Olympic Games.12.
