In the day, the streets arc always bustling with people from all over the world. After all, the city has long been China’s most cosmopolitan city, having been the epicenter of trade and cultural exchange between Chinese and foreigners since the city was forced to open its door to the world in 1843 after the First Opium War (1840-42).Shanghai’s ubiquitous delivery people can be found on the roads even past midnight, rushing from point to point on their trusty electric scooters to satiate the hunger of night owls. Even before the break of dawn, pensioners can be found gathering in parks, ready to kick start their day with a tai chi session.For others, this energy is generated from the friction between the contrasts the city has. Indeed, it does not take long for one to realize that Shanghai's charmlies in it being a binary of old and new.Here, charming neoclassical architecture and art deco structures stand alongside modem buildings with shimmering glass and metal facades, rustic (质朴的)lane houses and shikumen buildings. Humble mom-and-pop shops that look stuck in time can often be found right next tohipdining venues or industrial-chic fashion stores selling designer apparel.One of the best places to get an overview of these surreal contrasts is none other than the tallest building in the city — the Shanghai Tower in Lujiazui. Measuring a dizzying 632 meters in height, this architectural marvel boasts having the world's highest observation deck within a building or structure. It also comes with the world's fastest elevators which would get you from the bottom to the top at 20.5 meters per second.On the other side of the Huangpu River is where you would find the Bund, which is home to magnificent neoclassical buildings. The Bund is to Shanghai what Times Square is to New York or what the Champs-61ysees is to Paris. A trip to Shanghai would not be complete without exploring this iconic waterfront promenade.Autumn is the best time to experience Shanghai on foot, not merely because the weather is conducive for walking, but because this is when the roads and sidewalks in many areas are blanketed with a layer of color1 ful fallen leaves.8. Why is the example of delivery man mentioned?A. To make a contrast with pensioners’ biological clock.B. To illustrate the vibrant energy of modern Shanghai.C. To highlight the diligence and consideration of delivery man.D. To feature the courier delivery service in full swing.9. Which of the following is TRUE about the contrast of Shanghai?A. The contrast mainly arises from the First Opium War.B. The design of the Shanghai Tower stands for a contrast.C. A marked contrast is shown in the use of building materials.D. The dishes served in mom-and-pop shops represent the outdated flavor.10. The underlined word “hip” in paragraph 5 is closest in meaning to________.A. photographicB. modestC. peculiarD. stylish11. Which of the following will be most probably discussed following the last paragraph?A. Stunning views of the Shanghai skyline.B. The best places to view the seasonal spectacle.C. The walking path thathugs the Huangpu River.D. Must-try dishes and food items typical of Shanghai.DI was at my parent’s dinner table. Before me was a worn journal of thin and discolor1 ed pages. It was my grandfather’s journal and now belonged to my father. My grandfather had passed away in the months leading up to my birth. I never got to visit the places he had frequented and the people who had been a part of his life’s journey.I was now about to enter his world, through the words he had left behind. Within minutes, I wascaptivatedby the power of the written words. In the magical script (笔迹) before me, I was transported to another age when food was an everyday art, planned, prepared and enjoyed in the company of others, and a time when people had the heart to pause their own lives to embrace (拥抱) each other’s struggles. All this was conveyed to me in the beauty of the words that flowed together to connect with the writer’s mind and understand the world they livedin.That kind of writing seems to be lost on us today. We have gotten used to writing in bite-sized pieces for a public looking for entertainment, and hungry for information. No wonder, there are nearly 200 million bloggers on the Internet and a new blog is created somewhere in the world every half a second. Instead of adding to our collective wisdom, most of these writings reflectthe superficiality (肤浅) and impatience of our day and age.This not only robs us of the skill of writing impressive essays, it also prevents us from exploring what is indeed important. Writing humbles (使谦卑) us in a way that is vital for our character growth, by reminding us about the limits of the self and our appropriate place in the vast flow of life. Writing frees us by helping us explore the unknown so that we really open up to magic of the world around us. I saw all of this in the writing of my grandfather. And I’ve seen it again and again in the writings of the greatest thinkers of humanity. Their writing reflect deep thought on issues of human importance.12. The underlined word “captivated” in the second paragraph can be replaced by “________”.A. puzzledB. frightenedC. attractedD. defeated13. In the author’s grandfather’s age, people ________.A. lived a hard lifeB. cared about each otherC. were fond of writingD. treated food as an art14. The author begins the text with her grandfather’s journal in order to ________.A. show her respect to her grandfatherB. present the importance of good writingC. express her interest in reading as well as writingD. raise the problems with today’s writing15. In the last paragraph, the author is trying to _________.A. discuss what good writing is likeB. express her strong desire to learn writing skillsC. stress the effects of her grandfather’s journal on herD. show her admiration for her grandfather’s writing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。

Virtual and augmented（增强的）realities are together known as mixed reality (MR). “American footballers are already using VR to better train their minds andread the field,” Ludden said. “This can allow players to perfect their skills without risking injury.”Canadian company D-BOX Technologies designs and produces moving seats found in cinema and theme parks.

The seats stimulate the force of gravity, speed and every shaking as Fl champion Lewis Hamilton zips around city streets.A simulation seat uses pre-programed data now. Someday, though, it could use real-time information sent by the car. “They couldbroadcast live content through a network in pop-up theaters around the world,” Ludden said. Say you want to experience the true stress of a batter being up against major-league baseball pitcher. “You can have a heartbeat added to the sensation on the seat and then you can feel it, boom, boom,” Maheu explained. “When he swings and hits the ball, you can have an impact.”One day, fans around the world could physically experience every game from their favorite player in real time. Ludden said that current and near-future technology could create “augmented stadiums” for live audiences. Panasonic launched its “Smart Venue” plans which included the overlaying of graphics, advertisements, player statistics and replays on the field of play at a pro football game. “If you are seated in the cheap seats, you can see this really useful.” “Fans may someday join in stadium wide games, using the field as a virtual gaming platform,” Ludden added.4.

Everyone in the family settled quickly into the city except me. Without my beloved beaches and endless blue—sky days, I felt at a loss and out of place. Until I made a discovery.Southbank, at an eastern bend in the Thames, is the center of British skateboarding, where the continuous crashing of skateboards left your head ringing .I loved it. I soon made friends with the local skaters. We spoke our own language. And my favorite: Safe. Safe meant cool. It meant hello. It meant don't worry about it. Once, when trying a certain trick on the beam（横杆）, I fell onto the stones, damaging a nerve in my hand, and Toby came over, helping me up: Safe, man. Safe. A few minutes later, when I landed the trick, my friends beat their boards loud, shouting: “Safe! Safe! Safe!” And that's what mattered—landing tricks, being a good skater.When I was 15, my family moved to Washington. I tried skateboarding there, but the locals were far less welcoming. Within a couple of years, I'd given it up.When I returned to London in 2004, I found myself wandering down to Southbank, spending hours there. I've traveled back several times since, most recently this past spring. The day was cold but clear: tourists and Londoners stopped to watch theskaters. Weaving（穿梭）among the kids who rushed by on their boards, I found my way to the beam. Then a rail—thin teenager, in a baggy white T—shirt, skidded（滑）up to the beam. He satnext to me. He seemed not to notice the man next to him. But soon I caughta few of his glances. “I was a local here 20 years ago,” I told him. Then, slowly, he began to nod his head. “Safe, man.

During the visit,Hamiltonstarted talking to one of the prisoners and asked what he was going to do when he got out. “He said he was going to get a job,”Hamiltonrecalls. “I thought to myself, wow, that’s going to be difficult with a criminal background.”The conversation madeHamiltonconsider how to help those who came out from prison.

His online courses will be set next year. “By March 1, 2022, anyone will be able to access the courses, either to become a certificated instructor or to access it for themselvesas a prisoner or part of the general population,”Hamiltonexplained.

It's a day to celebrate the lights that guide us home and the historic importance of lighthouses and their keepers, who not only guided ships into harbor but also played key roles in naval battles across the globe. Check out these fantastic lighthouses across the globe as well as recommendations on the best places to stay near them.Cape Byron Lighthouse, Byron Bay, AustraliaThe Cape Byron Lighthouse in Byron Bay, Australia was built in the early 20th century to help protect the Australian coastline.

But MacKenzie, a four-pound Chihuahua (奇瓦瓦狗), who was named winner of the 2020 American Hero Dog competition, is making the world a better place for humans and animals alike. Often called the “Oscars for dogs”, the award recognizes dogs who make great contributions to society.This year's competition attracted over 400 competitors from across the country. While all were impressive, it was tiny MacKenzie who won the judges' hearts. Born at a rescue shelter in Hilton, New York, in 2013, she had a cleft palate (腭裂) that required her to be tube fed for the first year of her life. A life-saving operation, performed in 2014, gave her the ability to eat and drink independently, enabling the tiny dog to focus on doing what she loved most: taking care of others.The seven-year-old Chihuahua is now gainfully “employed” by the Mid Foundation, a Rochester, New York-based non-profit organization that shelters and cares for animals born with disabilities. MacKenzie's official job is “to provide love and care for baby rescue animals born with birth defects”. The Chihuahua is good at her job and hasnurturedmany different species-from puppies to kittens to turkeys, squirrels, birds and even a goat. She acts as their mother and teaches them how to socialize, play, and have good manners.In addition to her role as an animal caretaker, MacKenzie also has the important job of greeting the foundation's volunteers and friends. The incredible dog, who has lost her ability to bark, also visits area schools to help children understand physical disabilities in both animals and people.

Which can be a suitable title for the text?A. MacKenzie—The Most Hard-working DogB. MacKenzie—America's “Most Heroic Dog”C. Chihuahua—Inspiration of Positive EnergyD. Chihuahua—Appeal for Animals' ProtectionCBecause of COVID-19, in many places, large gatherings of people aren’t allowed. In some areas, the rules are more strict, and people aren't allowed to leave their homes unless going out is ly necessary.These steps are very important for slowing the disease down. By doing this, governments can make sure doctors and hospitals are better able to deal with all the sick people, and that fewer people suffer in all. Usually, it's called “flattening the curve”.But if no one can go out, that means businesses which depend on visitors struggle. Many singers, bands, and other musicians would normally be giving concerts now. Instead, they have to find new ways to share their music and connect with their audiences. The Metropolitan Opera in New York has canceled(取消) its season, but it is showing a special live stream of a different opera each day on its website. Other opera companies have made similar moves. Several theater companies are either offering recorded versions of their plays online or posting videos of their actors performing.Nick Green wrote a musical play that was canceled because of the virus. He set up a website with links that allow people to enjoy the work of artists around the world who have had their projects canceled. He called his project the Social Distancing Festival. He sad it was a time when he should be doing something new, rather than feeling disappointed.Even TV shows have to find new ways to film their shows. Some late night TV shows have continued, but without audiences. Others are showing reruns.While their shows are on pause, some TV stars like Conan O’Brien and Jimmy Fallon have been filming short videos at home. Mr. O’ Brien plans to bring his show back on the air soon by filming with his own phone andtalking with guests over the Internet.8. What does the underlined phrase in Paragraph 2 refer to?A.

The absence of audiences.C. The efforts of Nick Green .D. Entertainment going online .DI was so worried about handing my little boy over during his first week of school, but you made it easier. You smiled at him like a mother would at her own child.You showed warmth and your hugs were always on offer.After a day in class with you, Charlie would come home singing. Whenever I hear Do Your Ears Hang Low or see him stretching to the sky when singing about the days of the week, I will think of you.I didn't tell you at the time, but I loved your morning song so much that Iimplementedit in my own class (I'm a teacher, too).When you saw I was troubled, you hugged me with your smile and I knew everything would be OK. You made parents feel as cared for as our children.In the short time I knew you; you taught me about the type of teacher I desire to be. You never seemed disturbed by the mountain of paperwork or impossible work-life balance that comes with the role. Instead, you appeared to embrace every minute.I can't understand why you've been taken from us. Telling Charlie was one of the hardest things I've had to do.I'm not sure he fully understands, but he told me he loved you and has been asking whether your"robot powers"will work in heaven.A friend once told me white feathers are angels telling us that loved ones in heaven are well. On the first day collecting the children without you，a white feather floated through the sleet (雨夹雪). Watching the younger ones bounce and gigle as they tried to catch it was beautiful.I wish I had told you all of this when you were with us.I hope that you knew how you brought happiness to everyone you met and how loved you were. Goodbye, Dear Friend.12. What does the underlined word "implemented" in Paragraph l probably mean?A. Looked back on.B. Looked forward to.C. Thought highly of.D. Made use of.13.

Trees can lower summer daytime temperatures by as much as 10 degrees Fahrenheit, according to arecent study. But tree cover in US cities is shrinking (缩减). A study published last year by the US Forest Service found that we lost 36 million trees annually from urban and rural communities over a five-year period. “If we continue on this path, cities will become warmer, more polluted and generally unhealthier for inhabitants,” said David Nowak, a senior US Forest Service scientist and co-author of the study. Nowak says there are many reasons why our tree cover is declining, including hurricanes, tornadoes, fires, insects and disease. But the one reason for tree loss that humans can control is sensible development.Nowak says there is a downside to trees too, such as pollen allergy (花粉过敏) or large tailing branches in storms, and people don’t like sweeping leaves. But, he says, there are ways cities and counties can manage trees to help communities thrive (繁荣). Urban forests especially need our help to replace fallen trees. Unlike rural areas, it is very difficult for trees to repopulate themselves in a city environment with so much pavement and asphalt (沥青). “A lot of our native trees can’t actually find a place to drop a seed so they can regenerate,” explains Greg Levine, co-executivedirector of Trees Atlanta. “That’s why the community has to go in and actually plant a tree because the areas just aren’t natural anymore.”Nowak says the first step is caring for the trees on your own property (财产). “We think we pay for our house, and sowe must maintain it. But because we don’t pay for nature, we don’t need to. And that’s not necessarily true.”4. Why does the author mention “trees can lower summer daytime temperatures”?A. To tell the temperatures in summer are high.B. To explain the reason of tree loss.C. To tell trees are helpful.D. To introduce the topic.5. How can humans control tree loss according to Nowak?A. Develop cities in reasonable ways.B. Prevent fires form damaging trees.C. Improve climate to let trees grow.D. Decrease insects in cities.6. Why do forests in cities need our help?A. Because trees don’t grow in a city environment.B. Because native trees don’t drop seeds any more.C. Because trees in urban areas can’t regenerate naturally.D. Because humans want to plant more trees.7. What is the purpose of this passage?A. Describe the importance of trees in cities.B. Appeal people to protect trees in their surroundings.C. Ask people to plant trees with the author.D. Show the number of trees in theUSis declining.CHi, Momis a hit inChina.

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 likely to 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 smokestoo 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.12. 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 men13. 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 hers14.

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 own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。

It has the world's largest stage on the water. The performances are different every year but they are usually united by one theme. The decorations（装饰）are very impressive and are worth seeing.Viva, ArtificialIslandArtificial islands are not something new. What makes this island special is that . it is floating.

Automata are built to look like humans or animals and give the illusion (错觉) of being able to move on their own, “The art form amazes me, becauseit combines various skills, from storytelling to mechanics, and the pieces are built with a sense of humor,” Yu says. His creations have caught the attention of well-known artists and his fancy pieces of art have attracted collectors worldwide.Interested in handcrafts as a boy, Yu first encountered automata designed by Japanese artist Kazuaki at an exhibition in 2015 when he studied at the Communication University of China inBeijing. “It was like meeting a like-minded friend, ” Yu says, recalling the moment. As an art and design major, he began to learn the craft by himself and, with the support of his tutor, he kept studying and examining automata in school.When he graduated in 2016, Yu landed a job at an advertising agency inBeijing. He stayed on at the company for three years because, at that time, he was not sure that he could make a living out of his hobby. While working as a designer Yu kept exploring and advancing his skills in wood carving and mechanics. Eventually, despite the job’s good salary, it was not enough to make up for not following his true passion. Finally, in 2018, Yu quit his job and returned toChengduto open his automata workshop.To keep himself occupied while running his workshop, he planted blueberries, raspberries and cherries. He watered, weeded and added fertilizer (肥料) every day. “Daily routines helped me calm down and inspire my creativity, which resulted in an automaton called To Observe the Autumn,” Yu says.Over time, Yu’s reputation grew and his business flourished (兴旺). Many of Yu’s creations are built with a dash of wisdom, a sprinkle of humor and are inspired by observations of real life.

Observation from daily life.7. Which of the following can best describe Yu’s story?A. There is no end to learning.B. Great hopes make great man.C. Actions speak louder than words.D. Experience is the mother of wisdom.CAccording to a survey published by the American Institutes for Research last year, a total of 57 colleges were operating some form of CBE programs and about 85 percent of all the higher education officials said they were either designing a CBE program at their school or were considering doing so.Students in a CBE program choose a central field of study, just as they would at a traditional college or university. Yet instead of attending a series of classes led by professors or teaching assistants at schools, the students study online and direct themselves.CBE programs require students to show their understanding of a given set of sills Students must prove their mastery of skills that relate to their field of choice by taking related exams. Once they have met all the requirements of their study programs, the students will get their degrees.CBE programs have made use of many new technologies, especially internet and online media. This helps reduce barriers for nontraditional and other students by bringing higher education to them. And programs that permit students to work at their own speed may save students' money by reducing the time it takes for them to earn a degree.But some educators have concerns about the value of the education that CBE programs offer. Johann Neem atWesternWashingtonUniversityargues that the purpose of higher education is not simply to help students mastercertain skills. It should teach students how to think critically (批判性地) understand the subjects they are studying more deeply and see how they are connected to other subjects. Only that way can they put the knowledge to better use.He said, “You need to explore, think .. get shaken, have a conversation and struggle. Andthose things take time.”Instead of supporting CBE, he adds, policy makers and educators should look for ways to improve access and reduce costs for traditional higher education.8. How are CBE programs different from traditional college education?A. They require students to choose their subjects.B. They offer shorter curricula and are less expensive.C. They heavily rely on the information technologies.D. They allow students to take easier examinations.9. What can we learn from Johann Neem's words?A Free access to traditional education should be provided.B. Higher education just focuses on critical thinking skills.C. Students should spend longer time completing the degree courses.D. College students should be challenged to explore around their subjects.10. How does Johann Neem's attitude toward CBE programs?A. Supportive.B. Disapproving.C. Sympathetic.D. Uncaring.11. What is the author's purpose in writing the text?A. To press policy-makers to provide more affordable education.B. To show the disadvantages of the traditional college education.C. To introduce a new controversial trend in the higher education.D. To encourage educators to improve the quality of CBE programs.DIn ancient times, Chinese used plant leaves or bird feathers as a fan during the summer time. This was the earliest form of the fan. The first real fan was made back in the era of Yao and Shun period thousands of years ago. Since then,Chinese-made fans have become a vital part of Chinese art and culture. At the beginning, the fan functioned as a tool to generate a current of air in the hot weather. Now electric fans such as ceiling fans andother technological breakthroughs have taken the place.Long ago, fans caught the attention of ancient Chinese artists by chance. Thereafter, a unique fan art gradually took shape in the history of Chinese culture. Fan art usually includes Chinese calligraphy, paintings, or poems on the sectors（扇区）. Special skills are needed to write or paint on them.Due to its history and partly because of its unique shape, Chinese would soon develop the tradition of using fans as ornaments（装饰品）. Fans are made in different sizes and different color1 s to meet the needs of each request. Other Chinese ornaments, such as the Chinese knot, the green jade, and the Spring Festival picture, are often combined in each design.The value of fans depends mainly on the materials used and the level of craftsmanship that is involved during the process. Feather, paper, jade, bamboo and silk have all been used as ideal materials to make fans. Ancient Chinese even made iron fans to serve as deadly weapons（武器）in Chinese martial arts. Fans made by famous craftsmen are often characterized by pretty designs and detailed workmanship, and thus become favorites of collectors. Fans with masterpiece fine art like calligraphy or paintings are even more valuable.12.What is the first paragraph mainly about?A. The origin of fans.B. The materials of fans.C. The popularity of fans.D. The production of fans.13. Why do Chinese use fans as ornaments?A. They are made of valuable materials.B. They reflect the beauty of Chinese culture.C. They convey literature works on the sectors.D. They are often combined with other ornaments.14. Which of the following makes a fan favored by most collectors?A. Its advanced function.B. Its complex character.C. Its artistic handicraft.D. Its various applications.15. What can we infer about the fan from the text?A. Chinese send fans to their friends as gifts.B. Chinese ornaments can meet different requests.C. Traditional fans have lost their functional value.D. The fan plays different roles with the change of time.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学年上海市建平中学高三英语上学期期中试题及答案解析
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.

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。

Plus, representing your country is a lot of pressure. However, two athletes recently showed the world another quality that is definitely worth championing.Qatar's Mutaz Essa Barshim and Italy's Gianmarco Tamberi were competing in the high jump on Sunday when they reached a stalemate (僵局). Both men had managed to jump over a surprising 2.37 meters with no faults along the way. However, after three attempts neither managed the next level of 2.39 meters.An Olympic official suggested ajump-offbetween the two friends and rivals (竞争对手) to determine who would get the gold medal. But Barshim had another plan to reward their efforts.“Can we have two golds?” he asked the official.The official agreed and the two men jumped for joy. This was the first time a gold medal had been shared since 1912. “He is one of my best friends, not only on the track, but outside the track. We work together. This is a dream come true.” shared Barshim.The decision to share the medal was particularly meaningful to Tamberi. The Italian had suffered an ankle injury that prevented him from competing in the Rio Olympics in 2016, and it nearly put an end to his career altogether. So this year he brought along his cast to this year's Olympics with “Road to Tokyo 2021” to inspire him along the way.For Barshim, the gold has topped off his already impressive medal collection, having received a bronze and a silver medal in 2012 and 2016 respectively.Despite all the glory of receiving a gold medal for their countries, their achievement means so much more.

This love letter to the cleansing beauty of a good cry is a comforting thought at atime when the continuing stress of the COVID-19 has added heaviness to each of our lives.Scientifically, de Rivarol's poetic image doesn't, if you'll forgive the words used in the poem, hold water. There's limited research on crying, partly because of the difficulty of copying the behavior of real crying in a lab. But even within the previous studies, there's little evidence to suggest that crying provides a physiological cleansing of poisons in people's body.Psychologists believe the relief of a good cry connects with a different emotional process. “It seems that crying occurs just after the peak of the emotional experience, and crying is associated with this return to homeostasis: the process of maintaining a stable psychological state,” said Lauren Bylsma. He also said holding back tears can have negative physical consequences, including headaches and muscle tension. Such restriction can also limit our experiences of joy, gratitude and other positive emotions if we avoid acknowledging our feelings.For me crying has been easier said than done during the COVID-19. Psychologists say it's normal to feel stopped up by the stresses of the past year. We should find opportunities to release and process our emotions.Watching a tear-jerking movie, having an emotional conversation with a close friend, and writing in a journal are healthy ways toelicita cry. Physical activity like light-footed walking or even dancing can also signal our bodies to release some emotional tightness. We can then open up to the flow of feelings that leave us feeling lighter and refreshed—like a clear sky after a soaking rain.8. What is the weakness of the studies ever clone on crying?A. They were clone in a laboratory setting.B. They cared little about different forms of crying.C. They were always concentrated on people's daily life.D. They showed little about the positive physical effect of crying.9. What is the function of crying according to Lauren Bylsma?A. Curing people of their diseases.B. Keeping emotionally balanced.C. Producing negative mental results.D. Expanding people's experience of joy.10. What does the underlined word “elicit” in the last paragraph mean?A. Produce.B. Postpone.C. Control.D. Repeat.11. What are people advised to do according to the text?A. Learn to hold back their tears wisely.B. Share their emotion with their colleagues.C. Have a good cry when necessary.D. Try to avoid admitting our feelings.DBritish sculptor Jason Taylor has made it his mission to use his talent to conserve our ecosystems by creating underwater museums. Over the years, the environmentalist has put over 850 massive artworks underwater worldwide. On February 1, 2021, Taylor launched his latest work — The Underwater Museum of Cannes.―The main goal was to bring attention to the fact that our oceans need our help,‖ Taylor told Dezeen. ―Ocean ecology has been destroyed by human activity in the Mediterranean over the past few decades, and it is not obvious what is taking place when observing the sea from afar.‖The Underwater Museum of Cannes contains 6 sculptures featuring local residents of various ages. They range from Maurice, an 80-year-old fisherman, to Anouk, a 9-year-old student. Towering over 6-feet-tall and weighing 10 tons, the faces are sectioned into two parts, with the outer part like a mask. The mask indicates that the world’s oceans appear powerful and unbeatable from the surface but house an ecosystem that is extremely fragile to careless human activities.Though the waters surrounding the sculptures now appear a pristine blue, the seabed was filled with old boat engines, pipes, and other human-made trash when the project began about four years ago. Besides removing the trash, Taylor also restored the area’s sea grass. Just one square meter of the sea grass can generate up to 10liters of oxygen daily. The sea grass also helps prevent coastal erosion and provides habitats for many ocean creatures.―The idea of creating an underwater museum was to draw more people underwater and develop a sense of care and protection,‖ Taylor told Dezeen. ―If we threw unwanted waste near a forest, there would be a public outcry. But this is happening every day in our surrounding waters and it largely goes unnoticed.12. Why does the outer part ofthe sculptures look like a mask?A. To popularize the features of the locals.B. To remind people to protect themselves.C. To reflect people’s protection of the ocean.D. To stress the sensitiveness of the ecosystem.13. What’s paragraph 4 mainly about?A. How the project was started.B. How the sea grass was restored.C. What recovery effort the project made.D. Why the surroundings were improved.14. What can we infer from what Jason Taylor said in the last paragraph?A. The situation of the ocean is easily ignored.B. The destruction caused to the ocean is noticeable.C. Forests play a more important role in ecosystems.D. People have zero tolerance to damage done to nature.15. What might be the best title for the text?A. The Underwater Museum, a long way to go.B. The Underwater Museum, a big difference to the sea.C. The Underwater Museum, an appeal to conserve ecosystems.D. The Underwater Museum, a masterpiece of Jason Taylor.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学年上海市建平中学高三英语期中考试试题及答案
2019-2020学年上海市建平中学高三英语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AIn his 402nd anniversary year, Shakespeare is still rightly celebrated as a great language master and writer. But he was not the only great master of play writing to die in 1616, and he is certainly not the only writer to have left a lasting influence on theater.While less known worldwide, Tang Xianzu is considered one of Chinas greatest playwrights and is highly spoken of in that country of ancient literary and dramatic traditions.Tang was born in 1550 inLinchuan,Jiangxiprovince. Unlike Shakespeare's large body of plays,poems and sonnets (十四行诗), Tang wrote only four major plays: The Purple Hairpin, Peony Pavilion (《牡丹亭》), A Dream under the Southern bough, and Dream of Handan. The latter three were constructed around a dream narrative, a way through which Tang unlocked the emotional dimension of human desires and ambitions and explored human nature beyond the social and political limits of that time.Similar to Shakespeare, Tang's success rode the wave of a renaissance (复兴) in theater as an artistic practice. As in Shakespeare'sEngland, Tang's works became hugely popular inChinatoo. During Tang'sChina, his plays were enjoyed performed, and changed. Kunqu Opera, a form of musical drama, spread from southernChinato the whole nation and became a symbol of Chinese culture. Combining northern tune and southern music, kunqu Opera was known for its poetic language, music, dance movements and gestures. Tang's works benefited greatly from the popularity of kunqu Opera, and his plays are considered classics of kunqu Opera.While Tang and Shakespeare lived in a world away from each other, there are many things they share in common, such e humanity of their drama, their heroic figures, their love for poetic language, a lasting popularity and the anniversary during which we still celebrate them.1. Why is Shakespeare mentioned in the first paragraph?A. To describe Shakespeare's anniversary.B. To introduce the existence of Tang Xianzu.C. To explain the importance of Shakespeare.D. To suggest the less popularity of Tang Xianzu.2. What's possibly one of the main theme of Tang's works?A. Social reality.B. Female dreams.C. Human emotions.D. Political environment.3. What does the author mainly tell us in Paragraph 4?A. The influence of Kunqu Opera on Tang's works.B. Tang's success in copying Shakespeare's styles.C. The way Kunqu Opera became a symbol of Chinese culture.D. Tang's popularity for his poetic language and music.BWith graduation days being celebrated all over the country, a student who has to use a wheelchair honored his mother on his graduation day in a special way. Easley High School graduate, Alex Mays surprised people present when he got up and walked across the stage at Clemson's Littlejohn Coliseum.“I was really happy—it made me feel good,” Alex said.Alex was not given a chance to live right from his birth. He was born at 25 weeks and weighed just 1 pound, 10 ounces at birth. When he was very young, he had a disease and lost the ability to walk. After his mother's death in 2013, Alex had several other difficult life changes until he came to live with his grandparents, Dousay and her husband, Dewayne. Dousay said that when Alex came to live with them, they decided to bring him up in the best possible way they could.Last fall, Alex said that he would walk across the stage to get his diploma to honor his late mother. He practiced hard and worked with a physical therapist for 9 months to complete his plan.The only help Alex got was from his mom's best friend, Tonya Johnson, who pushed his wheelchair to the stage wearing one of his mother's favorite shirts. “I had support from my family. I couldn't have done it without them,” Alex said.“Alex made everyone in the building feel encouraged that day” Pickens County School District public information specialist John Eby said. “The school teachers knew he was going to get up to get his diploma, but the distance he walked was a surprise, even to them,” Eby said.“Some of life's most important tests aren’t given in a classroom; Alex tested himself and passed with flying color1 s,” Eby added.4. In what way did Alex honor his late mother on his graduation day?A. By dressing like her.B. By saying sorry to her.C. By inviting her best friend.D. By walking to get his diploma.5. What can we learn from Paragraph 3?A. Alex was born healthy.B. Alex went through a lot.C. Alex had a purpose in life as a child.D. Alex has lived with his grandparents all the time.6. What did Alex also express on his graduation day?A. His big regret in life.B. His feelings for hisschool.C. His thanks for his family.D. His will to complete his study.7. Which of the following words can best describe Alex?A. Strong-minded.B. Warm-hearted.C. Cool-headed.D. Easy-going.CThe Chinese philosopher (哲学家) Confucius once said, “Time flows away like the water in the river.” This is especially true as the novel coronavirus pneumonia outbreak has affected millions of people in China, andthe whole nation has been working day and night to fight the epidemic.In late January, when an increasing number of people in Wuhan were suspected to be infected, and hospitals didn't have adequate beds for them, two special hospitals—Lei shenshan Hospital and Huo shenshan Hospital were built. These two makeshift (临时的) hospitals were built to treat pneumonia patients infected with the novel coronavirus.HuoshenshanHospitalhas 1,000 beds and covers 33,900 square meters, andLeishenshanHospitalhas 1,500 beds and a total area of about 79,000 square meters. More than 4,000 workers worked 24/7 in two shifts, and nearly 1,000 large-scale pieces of equipment and transport vehicles helped the project on site. The two hospitals were built in an amazingly short time. It only took 10 days for people to build Huo shenshan, and 14 days for Lei shenshan.This certainly wowed many people overseas. “It's incredible that two hospitals with 2,500 beds can be built in a short period. It's just hard to believe,” a foreigner named Stuart told People's Daily. In the meantime, Chinese companies have also taken actions quickly in this battle.“The automobile industry is highly industrialized with strong capabilities in comprehensive manufacturing, purchasing materials, production lines and output of technologies,” Shi Jianhua, deputy secretary-general of China Association of Automobile Manufacturers, told CCTV News. “In this special time, when the nation needs more masks, it's time for us to quickly respond and shoulder the social responsibilities.”Indeed, a fast response is crucial in any crisis. In this special time,Chinacan't afford to waste a second in the fight against the epidemic. After all, time equals life during this crisis.8. Confucius' saying “Time flows away like the water in the river.” is mentioned to ______.A. arouse readers' interest in the passage.B. introduce the subject of the passage.C. present the background information.D. stress the value of time in epidemic.9. What can we learn about Lei shenshan hospital and Huo shenshan hospital?A. They are new hospitals for health care inWuhan.B. They were built in minimal time.C. Over 4,000 workers worked continuously.D. Stuart found them too massive to believe.10. We can infer from Shi Jianhua's words that the automobile industry inChina______.A. had no medical supplies factories before.B. guarantees whoever in need enough masks.C. has capabilities to give timely response.D. has strong abilities in manufacturing.11. What does the passage mainly talk about?A. China fights epidemic against the clock.B. Twospecial hospitals were constructed.C. Chinese firms acted quickly and effectively.D. Time is crucial for people in overcoming crisis.DDepression（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 stressresilience 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 fit as 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.12. 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.13. What are men with low stress resilience likely to do?A. Smoke more.B. Eat more.C. Sleep less.D. Do less exercise.14. 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.15. In which section of a newspaper may this text appear?A. Entertainment.B. Health.C. Education.D. Fashion.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。
