2019-2020学年江苏扬中高级中学高三英语下学期期末试卷及答案解析

2019-2020学年江苏扬中高级中学高三英语下学期期末试卷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AThe COVID -19 pandemic has affected all aspects of life, including the way we travel. But for those who are looking to expand their horizons while still staying safe, the following three travel trends in 2021 may provide inspirations. Let’s take a look.StaycationWith many travel restrictions during the pandemic, people preferred traveling to nearby places in 2020. This trend continues in 2021. According to search data, 62 percent of people are interested in taking a vacation within driving distance of home. People who live in large cities want to get back in touch with nature. Travelers are looking for places different from their everyday accommodations, for example, farm stays, villas and cottages.Pod travelWhile 2020 saw a rise in solo travel and isolated adventures, 2021 shows that people want to be more connected. “Pod travel”, or gathering in isolated spaces with loved ones, is growing in popularity. 85 percent of survey respondents favor traveling with family or friends, and over half of the trips searched include three or more people. Pod travel is here to stay for those who want to safely be together while reducing risks associated with socializing with others.Remote working and travelingMany people worked and learned from home in 2020 because of the pandemic. Remote working blurs the line between working and traveling. There was a 128 percent increase in the mention of phrases such as “relocation”, “relocate”, “remote work” and “trying a new neighborhood”. People are actively booking longer stays (e. g. two plus week trips) in small to mid—size cities with access to immersive natural surroundings and wide—open spaces.1.What can we learn about Staycation?A.Travelling to the countryside.B.Taking an isolated adventure.CHaving holidays in nearby places. D.Staying indoors all by oneself.2.What’s special about Pod travel?A.Traveling alone.B.Traveling far away.C.Traveling while working.D.Traveling with loved ones.3.Where might we find the text in a magazine?A.Medicine.cation.C.TourismD.Career.BFor years, Zach Ault, a father of three, enjoyed being physically active. He was even training for a half-marathon. But in 2017, he took time off to recover from an infection. After recovering, he tried to continue his runs but could not complete them. He was not able to spend time with his children. He had to cut back his job. Even sleeping as much as 16 hours a day made no difference in his condition.“His body had literally hijacked him and it wasn't going to allow him to push through, ” said Anne Ault, his wife. After months of testing, doctors announced their result-chronic fatigue syndrome, a disease that makes an individual feel extremely tired.This fatigue lasts more than six months and becomes worse after any kind of physical exertion (费力活动). Patients may have difficulty standing upright. They also may have trouble thinking, often described as a “brain fog”. There are no approvedtreatments, or even tests to help with diagnosis. There is no way to predict who will recover and who will have a severe case that lasts for years.Now the doctors at the National Institutes of Health (NIH) are conducting a unique study to learn more about the condition. Zach Ault is one of the subjects in the study. When Ault rides an exercise bicycle, scientists measure how his leg muscles use oxygen. Afterward, doctors fit a special cap on Ault's head to measure electrical activity in his brain. They then send him to spend the night in an air-tight room where air has been removed with pipe for additional study. Scientists measure oxygen and carbon dioxide levels to tell how much energy Ault is using, minute by minute. “We're figuring out how his body adjusts to an exercise load, or a stress load.”“It's hard not knowing if or when I'm going to recover, ” he said. But Ault says the study did help him learn about the disease. And it gave him ideas about how to save up his energy.4. What was Zach Ault's life like before 2017?A. He was fond of exercising.B. He won several half-marathons.C. He spent much time lying in bed.D. He was busy looking after his children.5. How did the infection affect Zach Ault?A. He lost his job.B. He was unable to sleep.C. He became too weak to do sports.D. He was tired of running a half-marathon.6. What can we learn about chronic fatigue syndrome?A. It usually lasts no more than months.B. It is likely to cause thinking disorders.C. Patients with it need to stay in bed all day long.D. Patients with it should avoid any kind of exercise.7. What does Zach Ault think of the study?A. It helped him cure his illness.B. It helped him recover and stay fit.C. It taught him how to enjoy cycling.D. It brought him new ideas about fighting diseases.CA PhD student inMichigandefended her paper while wearing a skirt madeof rejection letters she received while studying. 29-year-old Caitlin Kirby printed out 17 of her rejection letters — from scholarships, academic journals, and conferences — then folded each one into a fan. She connected them in rows, and by the end she designed the item into a skirt and wore it.She said that the idea behind her unique clothing item came out of a desire to normalize rejection and take pride in overcoming it. "The whole process of revisiting those old letters and making that skirt sort of reminded me that you have to apply to a lot of things to succeed," she said. "A natural part of the process is to get rejected along the way."Caitlin's adviser, Julie Libarkin, a professor of earth and environmental science atMichiganStateUniversity, also encourages the acceptance of failure in her students. Libarkin believes it's important for students to get into habit of applying for things, and to get used to the feeling of rejection, so she encourages them to chase after any opportunity that comes their way. If a student doesn't get the grant or the spot in the academic journal, that's okay. They'll still have learned something in the process.As for Caitlin? Her rejections over the years have led to great things: Since her doctorate, she's won a scholarship to do further research on urban agriculture inGermany.Currently, she's a post-doctoral researcher at the University of Nebraska-Lincoln. As for what the future holds? "I'm prepared to receive a few more rejection letters along the way," she joked heartily, "Maybe I'll make a longer skirt."8. What can we learn about Caitlin Kirby's rejection letters?A. She received 17 rejections in total.B. 29 of her rejections were from journals.C. The rejections were connected into a fan.D. She made some rejection letters into a skirt.9. What is Julie Libarkin's attitude towards Caitlin's action?A. Favorable.B. Ambiguous.C. Skeptical.D. Opposed.10. Which of the following words can best describe Catlin?A. Creative and considerate.B. Caring and determined.C. Optimistic and humorous.D. Generous and intelligent.11. Which of the following may Caitlin agree with?A. Hard work pays off.B. Education is the entrance to success.C. Self-respect earns more respect.D. One needs to normalize failures.DWe have most friends at the age of 26 afterhaving spent the first quarter of our lives building up our friendship circle, new research has claimed.The research into friendship shows that our social circle peaks at 26 years and 7 months, at which we typically have five close friends. Women are most popular at 25 years and 10 months, with men hitting the highest friendship point a little later at 27 years and 3 months.The research, by Forever Friends, shows that about a third of adults meet their closest friends while at school, with about a fifth saying they meet them at work.Social networks such as Facebook and Twitter now also play a major role in building new friendship. The research points out that 25 to 34-year-olds make 22 friends via Facebook, compared to 18 to 24-year-olds who make 12, and 35 to 44-year-olds who make just four.Forever Friends' relationship coach Sam Owen says, “It is no coincidence that over a third of us meet our best friends at school. It is a key time in our lives when friendship is growing through sharing notes, giving gifts, seeing each other regularly and laughing a lot. As adults we can often forget how powerful these small things are and how the little things can make a difference."Later in life we find ourselves losing friends. Over half of us lose friendship through moving, while 36% saythat over time they grow apart from close pals. Having children also causes 19% todrift away fromchildhood friends.With growing pressure being put on friendship these days, it's important to make time for our friendship.12. How many friends can a 20-year-old college student make via Facebook?A. 22.B. 18.C. 12.D. 4.13. In Paragraph 5, the author is trying to tell the readers ________.A. how important making friends isB. school time is an important period to develop friendshipC. how much has been done to keep friendshipD. that friendship is not easy to keep14.

2019-2020学年江苏扬中高级中学高三英语下学期期末试题及答案

2019-2020学年江苏扬中高级中学高三英语下学期期末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AHottest Travel DestinationsSometimes figuring out the best place to go can be difficult. Here are some hottest travel destinations that offer some of the most beautiful, artistic, and fashionable places on the globe.Ibiza, SpainWhile Ibiza is knownas a party city, there is far more to do in this historic town than simply drink and dance under the stars. Built mainly in the second century, it’s a world heritage site with architecture dating back to as early as the 7th century. Don’t miss Charo Ruiz, Ibiza’s most famous fashion brand. Plus, the Ibiza Fashion Festival takes place every June.Tangier, MoroccoKnown as the “door to Africa”, Tangier has a rich and complex history dating back thirty centuries. It has all the beauty of the natural world. After spending a morning sunbathing by the Mediterranean Sea, get in some amazing shopping and discover great deals on everything. Before you head home, stop off in Marakesh to visit some of the top Moroccan designers.Havana, CubaStepping onto the streets of Havana feels like stepping back in time. For a day of sightseeing, check out the remaining architecture of Old Havana, which was built ten centuries ago. You can easily do it with one of the area’s many walking tours. Or visit the Museum of Rum for a taste of the island’s most popular wine. You might come across a clothing shop offering some classic finds!Melbourne AustraliaBuilt largely during the 1850s gold rush, Melbourne remains as alive as ever. Make sure to check out the hottest Australian brands. Moreover, visit the Block Arcade in Collins Street to see some of the 19th century architectural details the world has to offer. And, if you want to catch the largest consumer fashion festival in the world, grab tickets for the yearly Virgin Australia Melbourne Fashion Festival.1.What can visitors do in both Ibiza and Havana?A.Taste local wine.B.Visit modern Museums.C.Appreciate ancient buildings.D.Enjoy parties under the stars.2.To attend the globally largest consumer fashion festival, you have to go to ________.A.SpainB.MoroccoC.Havana.D.Australia3.Which of the following cities is the oldest?A.Ibiza.B.Tangier.C.Havana.D.Melbourne.BScientists have long sought to prevent sharp memories from dulling with age, but the problem remains unsettled. Now research published in Scientific Reports suggests virtual reality might help older people recall facts and events based on specific details.The study involved 42 healthy older adults from the San Francisco Bay Area. Half spent a dozen hours over four weeks playing a virtual-reality game called Labyrinth; they wore headsets and walked in place, walking virtual neighborhoods while completing small tasks. The other half, in the control group, used electronic tablets to play games that did not require recalling details. After 15 sessions (期), the latter performed roughly the same as before on a long-term memory test. But the Labyrinth players gain an improvement in memory through the VR game. A scientist Peter Wais of the University of California said the improvements brought them up to the level of another group of younger adults taking the same memory tests.Meredith Thompson, an education researcher, studies learning through VR games but was not involved in the new study. It would be great to actually follow people over time and see what this type of game does for long-term memory. She says, adding VR can provide greater involvement than other games. Wais's team is now investigating how long the observed effects last and which elements of the training have the most impact.A cognitive (认知)psychologist, Daniel Simons, who was also not involved in the study, notes experiments with other games that claim to train the brain have often failed to evaluate this. And it remains unclear how test performance in a laboratorysetting might translate to real-world situations. The outcome, Simons notes, “needs to be repeated, ideally with a much larger group, before it’s treated as a strong finding.”For now, Wais says, the team hopes its studies with similar-sized groups will help draw funding to test the game in a larger pool of participants.4. What is the passage mainly about?A. People's memory gradually fails as they age.B. People of different ages should play VR games.C. Virtual reality changes people's memory.D. Virtual reality improves older adults' memory.5. What is Meredith Thompson's attitude toward the research?A. satisfied.B. enthusiastic.C. cautious.D. concerned.6. According to the scientists, the research needs to be improved due to ________.A. the lack of financial support.B. the limited pool of participants.C. the unsatisfying test performance.D. the impractical application in real world.7. Where may the passage come from?A. A novel.B. A review.C. A magazine.D. A guidebook.CConcerns about health, animals and the environment are leading more people to remove meat from their diet. Plant-based meat alternatives (替代品) increasingly appear in supermarkets and restaurants. But what some people call clean meat-meat grown from cells in a laboratory—is still an idea that is just beginning.More than 24 companies are testing lab-grown fish, beef and chicken. These businesses hope to enter the alternative meat market, which could be worth $140 billion by 2029. One of the companies, Shiok Meats, grows its product by taking shrimp cells and keeping them at a fixed temperature. They are then given nutrients in a solution (溶液). The cells become meat in four to six weeks.This lab-grown meat’s price is high. One kilogram of it now costs $5,000, said Shiok Meats’ chief executive Sandhya Sriram. At that cost, a single pork and shrimp dumpling could be as much as $300. Sriram, avegetarian, hopes to cut the cost to $50 for one kilogram by the end of this year. “We are looking at next year, so we might be the first ever company to launch a cell-based meat product in the world,” Sriram said. “Shiok Meats still needs approval from the city’s food regulator, and that matters the most at present.”Although people increasingly demand meat alternatives, cell-based meat companies still faceresistance(抵制) to their products. In Singapore, some people said they would give lab grown meat a second thought. “I may not exactly dare to eat it, but I do find the idea appealing because the animals in the oceans are declining,” said 60-year-old Pet Loh, while sheshopped for shrimps in a Singapore market.Any alternative way of making animal protein without harming the environment is positive, said Paul Teng, aspecialist in agriculture technology at Nanyang Technological University. But, he added, more studies are needed to understand any negative result of making cellular protein.8. Why are more people eating less meat?A. Because lab-grown meat has more nutrition.B. Because plant-based food is getting popular.C. Because meat in the market is increasingly expensive.D. Because health and the environment are their concerns.9. What is the most important for Shiok Meats at present according to Sriram?A. Bringing down the price.B. Gaining consumers’ acceptance.C. Obtaining official permission.D. Getting ahead of other companies.10. Which word best describes Pet Loh’s attitude towards lab-grown meat?A. Doubtful.B. Uncaring.C. Negative.D. Positive.11. What is the text mainly about?A. A new way to make a fortune.B. Negative results of lab-grown meat.C. New research findings on healthy diet.D. A meat alternative grown in labs.DEmojis are very popular among mobile phone and social media users. While there are emojis of almost every kind imaginable, from dinosaurs to joyful tears and eggplants, there is no emoji for forgiveness. Seeing the need to show understanding, aFinnish group decided it was time for a "forgiveness" emoji.Every year, the Unicode Consortium, which sets the standards, adds new emojis to the emoji keyboard on mobile phones and computers. In 2019, the Forgivemoji campaign was launched. Forgivemoji's site made an open call to the public to give their designs for a new forgiveness emoji, with the goal of presenting the symbol to the Unicode Consortium and getting it accepted by people.Tuomo Pesonen, communications director of the Unicode Consortium, explained why the forgiveness emoji isindispensablein today's world. “In our modern communication culture, emojis are an important way of expressing human feelings beyond words.” The campaign gained popularity, reaching over two million people around the world. They received many designs, including a bandaged heart, two holding hands, and people from different cultures hugging.After hundreds of people offered their ideas for this emoji, the winner was announced in February 2020.Former Finnish president Tarja Halonen was selected to choose the winner as she has been important in building bridges between people. The emoji that will be presented to the Unicode Consortium is an image of two hands giving a thumbs-up symbol in front of a heart. If the Unicode Consortium accepts the design, it will become available to the public in late 2021.The Forgivemoji campaign goes far beyond having a strong influence on social media. The message of showing forgiveness and understanding is helpful for the world at large.12. What's the idea behind the Fogivemoji campaign?A. people develop pleasant habits.B. To get people more friendly to each other.C. To pick a forgiveness emoji for the public to use.D. To make mobile phones and computers more convenient to use.13. What does the underlined word “indispensable” in Paragraph 3 mean?A. Necessary.B. Different.C. Changeable.D. Interesting.14. Why was Tarja Halonen selected to choose the winner for the campaign?A. She launched the campaign herself.B. She designed the most popular emoji.C. She was familiar with the emoji history.D. She played an important role in relating people.15. What can be the best title for the text?A. Forgiveness is important for peopleB. Emoji for forgiveness is on the wayC. Emojis are becoming interestingly popularD.

2019-2020学年江苏扬中高级中学高三英语下学期期末试卷及答案

2019-2020学年江苏扬中高级中学高三英语下学期期末试卷及答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AFor some people, there’s no better companion than mans best friend-a dog. This four-legged pet can bring comfort and joy and provide much- needed exercise for you when it needs walkies! This probably explains why dog ownership increased last year because people spent more time at home during he CovID-I9 lockdown.However, as demand for a new dog increased, so did the price tag. Popular breeds, such as Cockapoos and Cocker Spaniels, saw even sharper price increases, and puppies have been selling for $3,000 or more.Animal welfare charities fearthat high prices could encourage puppy farming, smuggling (走私) or dog theft. An investigation found some breeders have been selling puppies and kittens on social media sites--something charities have called “extremely irresponsible”.But despite some new owners purchasing a dog legally, maybe from a rescue center or registered breeder, they’ve proved to be ill-prepared for life with a new pet, and the pet itself has found it hard tocome to terms withlife in a new home.Looking to the future, there are concerns about the welfare of these much-loved pets. Lan Alkin manager of the Oxfordshire Animal Sanct uary in the UK, notes: “At the moment, the dogs are having a great time, but separation anxiety could still surface when people go back to work.” And Cliare Calder from the UKs Dogs Trust rescue charity says, “The economic situation also means that some people may find they can’t afford to look aftera dog.” The message is not to buy a dog in haste and to pick one that fits into our lifestyle.1. The greater demand for dogs can cause the following problems except ________.A. illegal trade of dogsB. less dog farmingC. high prices of dogsD. online sale of dogs2. What does the underlined phrase"come to terms with"in paragraph 4 mean?A. Fit in withB. Go in forC. Make up for.D. End up with3. What can we learn from the last paragraph?A. Despite the problems, dogs are living happily.B. The writer has a positive attitude towards dogs future.C. Experts are worried that dogs will be unaffordable to people.D. The writer advises people to think twice before keeping dogs as pets.BIf you could travel back in time, which period of history would you visit? It’s a great question to ask your friends, and time travel is the subject of many science fiction films. Of course, sci-fi is familiar to most of us, butwhat is cli-fi? The simple answer is climate fiction which focuses on the subject of climate change.Many of the cli-fi examples we watch tend to be disaster films. It could be solar flares (太阳耀斑), ice ages devastating (摧毁) the planet, extreme flooding swamping the earth with water, or super-storms that threaten life as we know it. While films and novels of this style are often subject to the typical images of a hero or heroine battling to save the day, what sets it apart from most sci-fi films is that the plots will often draw on apparently reasonable outcomes in the near future.Climate change and the potential threats have long been established. Some believe that the issue of climate change has even led to more fans watching films to learn more about what's happening to the world – seeing it as a form of edutainment. A study conducted by the Yale programme on Climate Change Communication tested the effects that two climate fiction novels can have on its readers and found “significant positive effects” in terms of their attitudes and beliefs towards the climate crisis – for example, understanding global warming will harm them and future generations.Most climate films are not only extremely popular action films, but also cause our fear of what some see as the approaching end of the world. This sounds bad, but according to a study conducted on 310 adults in the US, watching such scary films can help us feel more prepared and less alone in situations such as the pandemic (疫情). So, it looks like cli-fi is hereto stay – and there seem to be some benefits. Whether it’s there to educate, entertain or prepare you for a climate crisis, it might have a role to play.4. Which of the following may be the subject of cli-fi?A. Time travel.B. Global warming.C. Weather forecast.D. Economic climate.5. What can we learn about cli-fi films from paragraph 2?A. They are often about extreme natural disasters.B. They want to show that man can conquer nature.C. They usually have similar plots with sci-fi films.D. They can show the true near future of the world.6. Why is the study conducted by the Yale programme mentioned in paragraph 3?A. To prove that climate change has potential threats.B. To show that people like climate fiction novels.C. To tell that cli-fi novels have positive effects on readers.D. To explain how the climate crisis affect the human being.7. What does the writer mainly want to tell us in the last paragraph?A. Cli-fi films are very popular as action films.B. A study was conducted on 310 adults in theUS.C. The pandemic make people scared and alone.D. Cli-fi films are useful and will be here to stay.CAfter 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 said8. 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.9. 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.10. 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.11. 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.DAn ancient tomb was recently discovered in southern Siberia in which there may be treasure, priceless objects, and the 3, 000-year-old remains of an ice mummy.Swiss scientist Gino Caspari with the University of Bern was looking carefully at the pictures of the area in the Russian Tuva Republic, when he came across what appeared to be a tomb. It is a tomb of the Scythians, an ancient group of Eurasians.This summer, together with researchers from the Russian Academy of Sciences and the Hermitage Museum, a dig at the site not only proved Caspari's idea, but told us the site is the largest and oldest of its kind ever discovered in what's increasingly known as the “Siberian Valley of the Kings.”While any discovery dating back to a period between the Iron Age and Bronze Age is exciting, it's the nature of this site that makes scientists want to begin carefully clearing away the layers of rock and earth. First, the tomb appears to have never been dug, because it is in a Siberian wetland faraway from the nearest place where people live. Second, and most important, is its possible resting place under a thick layer of permafrost.“There's permafrost in the area,” Caspari said. “There are really only a handful of permafrost tombs and veryfew that have not been damaged, where there have been ice mummies in good condition, and all the things in the tomb are untouched.”While not as large, other tombs discovered in the area have produced fantastical treasures and objects, including thousands of gold objects and other things about the past. By studying all these tombs, researchers hope to have a better understanding of the Scythian people.Caspari said his team is in a race against time to uncover the tomb and find out its secrets. “We now have to act fast,” he said, “because with the rising temperatures, the permafrost could melt and damage all the things in that tomb. And these are things that are over 3,000 years old, that look like new, like they were put there yesterday.”12. How did Caspari discover the tomb?A. By studying pictures.B. By visiting a Russian area.C. By talking with Russian researchers.D. By comparing other scientists,ideas.13. Why has the tomb remained untouched?A. It is covered by a lot of rocks.B. It is well kept by the Scythians.C. It is too small to draw attention.D. It is hidden in a wild cold place.14. Why do scientists want to uncover the tomb?A. To better protect the tomb.B. To save the treasures inside.C. To learn more about the Scythians.D. To have a good understanding of mummies.15. Why is Caspari's team racing against time to dig the tomb?A. The tomb is too old.B. It is getting hotter and hotter.C. Some treasures are being damaged.D. They want to save time for other tombs.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。

But it also presents a danger to the world in two important ways. First, the making of paper requires the loss of many millions of trees each year. And worldwide use of paper is expected to double in the next 40 years. Clearly, the planet cannot stand such a high rate of forest loss. The second great problem with paper is what happens once it is no longer useful. A large amount of wastepaper ends up in landfills, where it can produce harmful gases and finally contribute to global climate change.One simple solution can greatly reduce both of these problems: paper recycling. Instead of cutting down trees, recycle existing paper to feed the paper-making process.Paper is mainly made from cellulose (纤维素),which can be used repeatedly in papermaking. Unfortunately, it also means that paper waste takes a surprisingly long time to break down in landfills. So far, trees are the only source(来源) of cellulose that can fill the great demand for paper products. Therefore, recycling paper is simply one of the best ways to save trees. Thanks to advances in processing, recycled paper need not be the dark-color1 edstuff many of us are familiar with. It now can offer the same print performance as non-recycled paper.Effective recycling requires a continuous effort from everyone at all levels of society. The way to begin is with education and understanding. Once enough people realize the need for recycling, more effective recycling systems can be developed.The need is real. The massive loss of trees affects everybody on earth. Everyone should do their part torecycle paper and encourage government and industry to do the same. The world will be a better place for it!4. What can we infer from the text?A. The use of recycled paper will double in 40 years.B. Recycling paper helps relieve global climate change.C. Wastepaper can easily break down in landfills.D. There are not enough landfills for wastepaper.5. What makes recycled paper more acceptable?A. The great demand of trees.B. The low processing cost.C. Its dark-color1 ed feature.D. Its improved print performance.6. What does the author propose?A. Punishing the act of cutting trees.B. Recycling paper.C. Improving recycling system.D. Promoting paper industry.7. How is the text mainly developed?A. By analyzing causes and effects.B. By offering research plans and data.C. By discussing problems and solutions.D. By comparing strengths and weaknesses.CSometimes people make history. George Washington became the first president of theUnited Statesand made history. Sometimes wars make history. The two World Wars are examples. Sometimes nature even becomes part of history. Shaking earthquakes are recorded in history books.Sixteen years ago, nature caused just such a history-making event. In September 2005, Hurricane Katrina came ashore inNew Orleans,Louisiana. The deadly storm floodedNew Orleans. Before Katrina, no other big American city had ever flooded in the history of the country. This natural disaster caused great harm and death.New Orleansis located below sea level. This location places it at great risk. Levees were built to protectNew Orleansfrom the ocean. (A levee is like a wall between the city and the ocean.) When Hurricane Katrina came ashore, water moved over the levees into the city. Flooding made it necessary for everyone to leave the city. Before Katrina, Creole food (a special kind of cooking only inLouisiana) filled the air with delicious smells. The sound of jazz music traveled through the streets. Now the city has to return to its former glory.Before Katrina, ernment had never made everyone leave a city. People inNew Orleanshad to find shelter quickly. Some had to stay at theSuperdomeSportsCenter. Some rode on buses to other towns. Thousands drove their cars to get away from the storm. The roads and shelters filled up fast.The lesson learned from Katrina was that cities must be better prepared for big storms and other terrible disasters caused by nature. Being prepared might have kept more people safe. Hurricane Katrina is one of the history-making events that will be remembered forever. Today, history is still being made that will shape the future.8. What does the author tell us aboutNew Orleans?A. It was built above sea level.B. It had few jazz musicians after Katrina.C. It was the firstU.S.city that had been flooded.D. It created a wholly new way to cook after Katrina.9. What can we say about the levees?A. They were almost useless for fighting Katrina.B. They helped people leaveNew Orleansquickly.C. They made NewOrleansa special American city.D. They should be built to match the size ofNew Orleans.10. What might the author advise city governments to do?A. Put up more shelters in the city.B. Build more levees around the city.C. Teach people how to avoid floods.D. Try to get ready for natural disasters.11. What is the best title for the text?A. Storms are dangerousB. Katrina makes historyC. Floods shapeLouisianaD. History must be rememberedDA Hug from a Teenage BoyFifteen years spent in the field of education have provided Nancy Marra with many treasured moments. One of the most endearing happened when she was teaching second grade.That year, she decided to plan something special for the children: a Mother’s Day tea. After all the preparations were made for it, each child took home an invitation.Nancywas surprised and relieved to see that every mother was planning to attend. She even invited her own mother.Finally, the day arrived. That afternoon, each child lined up at the classroom door expecting the arrival of his or her mom. As it got closer to starting time,Nancylooked around and her eyes quickly found Jimmy. His mother hadn’t shown up and he was looking upset.Nancytook her mother by the hand and walked over to Jimmy. “Jimmy,”Nancysaid, “I have a bit of a problem here and I was wondering if you could help out. Since I’m going to be really busy today, I was wondering if you could keep my mother company.”Nancy’s mom and Jimmy sat at a table with two other mother-child pairs. Jimmy servedNancy’s mom her treats, presented her with the giftNancyhad made, and pulled out and pushed in her chair, just as they had practiced the day before. WheneverNancylooked over, her mom and Jimmy were in deep conversation Ten years later,Nancywas at a high school to take a senior class on a field trip, and there was Jimmy. On the way back,Nancyhad the students complete an evaluation form of their trip. She collected and checked the forms one by one.When she came to Jimmy’s evaluation page, he had written, “Remember our Mother’s Day tea we had in second grade, Mrs. Marra? I do! Thanks for all you did for me, and thank your mother, too.”As they began unloading at the school, Jimmy made sure he was the last one to go.Nancytold him she really enjoyed what he had written. He looked rather embarrassed, mumbled (咕哝) his own thanks, and then turned to walk away. As the bus driverbegan pulling the bus away, Jimmy ran back and knocked on the bus door. He jumped back on board and gaveNancya big hug. “Thanks again, Mrs. Marra. No one even knew my mom didn’t make it that day!”She ended her workday with a hug from a teenage boy who had probably stopped hugging teachers years ago.12. Why was Jimmy paired withNancy’s mother?A. Nancy was too busy to spend time with her.B. Jimmy’s mother didn’t come to the event.C. Nancy wanted Jimmy to get to know her.D. Jimmy could get along well with her.13.

Upset.B. Embarrassed.C. Grateful.D. Satisfied.15. Which of the following best presents the theme of the passage?A. No act of kindness is ever wasted.B. A friend in need is a friend indeed.C.

2019-2020学年扬中实验中学高三英语下学期期末考试试卷及答案解析

2019-2020学年扬中实验中学高三英语下学期期末考试试卷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AKate Humble: Books that changed my lifeKate Humble is a writer and broadcaster specializing in science, wildlife and rural affairs. Together with her husband site runs Humble by Nature, a rural skills education centre on working farm near Monmouth intheWyeValley.Winnie the Poohby A A MilneMy father used to read this to me when I was very young — he used different voices for all the animals. The characterization (角色设定) was so clever; we all know someone just like each inhabitant of the HundredAcre Wood: gloomy Eeyore; thick but loyal Pooh; enthusiastic Tigger.A A Milne was masterful in exploring the way they got along together, opening my eyes to how society really works.Last Chance to Seeby Douglas Adams and Mark CarwardineThis book tells of the authors, adventures as they set out to find the rarest of animals, those on the edge of extinction.Their travels are rather exciting and they share a wonderful humour, which really appealed to me. Yet underpinning (支撑) everything is the realization that we can't just sit back and allow species to disappear. PicturePalaceby Paul TherouxI've always loved Theroux's travel writing, but this novel took my breath away. The words aren't long or complicated but, fromthat first paragraph, his writing grabs you by the nose hairs and drags you along. I had an art teacher who told me, “You're only an artist when you've found your own style, not when you're copying someone else, and Theroux represents this.”1. Why did the author mention the characterization ofWinnie the Pooh?A. To indicate the book has realistic values.B. To show how adorable the characters are.C. To persuade people to learn from the characters.D. To prove the writer is good at creating characters.2. What didLast Chance to Seestrike into Kate's heart?A. Curiosity.B. Responsibility.C. Exploration.D. Devotion.3. Which writer does Kate Humble like for his original writing?A. A A Milne.B. Douglas Adams.C. Mark Carwardine.D. Paul Theroux.BNowadays medical technology seems to be advanced enough for doctors to perform brain transplants (移植). Though this procedure (程序) has only been successfully performed on animals so far, doctors are still hopingto perform this procedure on humans. However, in my opinion, brain transplants should not be performed at all, especially not on humans because of the large number of problems and side effects that could come along with. Hopefully these dangerous side effects will convince doctors not to perform this procedure on humans.Despite many benefits technology brings. I do not think this medical technology of brain transplants will help. We were all born with one brain and through childhood to adults our mind developed into who we are, so if with a different brain we would no longer be unique. A person with a different brain would seem to be a total stranger and in many ways they would be. No one should steal our identity from us, even if we are seriously injured, and change it to a completely new one. Also for the people who have died with healthy brains, that was their identity and it should not be given to anyone else.Another problem with brain transplants is how doctors can choose what are “healthy” or “normal” brains. An elderly person who has died would have an aged brain that would not be as efficient as younger person’s brain. Then would doctors have to find healthy brains of the same age as the person who needs it? This could also bring up other factors such as intelligence, sex, or physical problems that a person might have had before death. Also another problem might be how long a brain can be kept “alive” after death and how it can be kept “alive” without damage.Overall. my feelings about this operation are that it should not be done on humans until doctors have overcome all the problems and challenges that stand in their way of making human brain transplants successful.4. Why does the author think brain transplants should not be performed at all?A. The cost of the operation is extremely high.B. Doctors are not able to perform brain transplants.C. A good many problems and side effects may arise.D. This procedure has only been successful on animals5. What is the second paragraph mainly about?A. People shouldn’t give their healthy brains to others.B. Having a brain transplant means losing one’s identity.C. Transplanting brains is changing old brains into new ones.D. Having brain transplants indicates stealing identity from others.6. What is the writers’ attitude towards brain transplants an humans?A. indifferentB. favorableC. disapprovingD. objective7. What is the author’s purpose in writing the passage?A. To encourage brain donation.B. To stress the importance of brain operation.C. Toargue against brain transplants on humans.D. To introduce the technology of brain transplants.CAt the foot of the Tianmu Mountain in Zhejiang, a homestay (民宿) is attracting travelers from far and wide, which has won architectural (建筑学的) medal at the 2021 German iF Design Awards.The owners of the homestay are a couple in their late 30s who decided to return to their hometown three years ago. Li Xiumei used to be in charge of a division at a company in Hangzhou, and her husband was a sales director. It was an ordinary situation where Li’s husband was on business trips a lot and Li worked overtime on weekends. City life sometimes is not easy.In 2018, they quit jobs and went back to Dongtianmu village, which lies in a forest of bamboo. The first time they drove into the village was one late afternoon. The cooking smoke was rising from the foot of the mountain, which gave them a very different feeling form thecity.The homestay was built beside her husband’s old countryside house. The old house is preserved (保留), while a brand-new building was built on its side and the whole site is made up of for courtyards. It has been updated tohave a hall, a tea room, a kitchen, a dining room. Japanese cherry trees are planted in the east courtyard. A swimming pool is placed in the west courtyard, with a bar located on one side.Li and her husband love gardening and music, and their new home gives them enough space to continue their interests and relax in the heart of nature. Li wants to share the quiet country life, so she makes her new home a homestay. In 2019, the homestay became an online hit after guests shared their experiences on social media. “The longer I stay here, the more I feel it was the right choice to come back, and this is more meaningful than making money,” Li says.8. How did Li feel about city life?A. Satisfied.B. Tired.C. Attractive.D. Noisy.9. What impressed the couple when first driving to the village?A. The smoke of cooking.B. The forest of bamboo.C. The smell of the village.D. The feeling of loneliness.10. What can we infer about the homestay from paragraph 4?A. It is ancient and broken.B. It can hold many guests.C. It has been rebuilt bythe couple.D. It must have been carefully designed.11. What’s more meaningful than earning money according to Li?A. Continuing their music dream.B. Staying at the old house.C. Living in the countryside.D. Developing the economy of cities.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 lateryears if they have low stress resilience” said study author Dr. Bergh, “Our research has also shown that low stress resilience is also connected with a greater tendency towards bad behavior, such as higher risks of smoking, drinking and other drug use.”“Better fitness in adolescence is likely to help protect against later heart disease, particularly if people stay 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。

江苏省丹徒高级中学、句容实验高中、扬中二中2019-2020学年高一语文下学期期中试题【含答案】

江苏省丹徒高级中学、句容实验高中、扬中二中2019-2020学年高一语文下学期期中试题一、现代文阅读(36分)(一)论述类文本阅读(本题共3小题,9分)阅读下面的文字,完成1-3题。

①新冠肺炎疫情发生后,文艺工作者积极投入文艺创作,诗歌、绘画、书法、舞蹈等呈现井喷之势,形成了特殊时期的“抗疫文艺”现象。

②如何深化“抗疫文艺”书写?笔者认为应向中国美学精神礼敬,继承和弘扬中华民族直面灾难的大智大勇、顽强抗争的人文情怀;向抗疫现实靠拢,深入观察和把握党中央坚决打赢疫情防控阻击战的决策部署和显著成效,了解抗疫一线和身边可歌可泣的抗疫事迹,以及普通老百姓的悲欢离合故事;向灾难书写的纵深掘进,努力探寻“抗疫文艺”独特的内在美学意味和特定表达形式,在艺术追求中凸显当代中国“抗疫文艺”的风格特征和艺术气派。

因此,应从“国本、人本、事本、文本”四个方面提高认知把握能力和提升艺术表现水平。

③国本,即一国之本,是中国特色社会主义根本制度。

“文变染乎世情,兴废系乎时序。

”在观察感悟和艺术反映防控阻击新冠肺炎疫情现实时,应自觉摒弃轻信谣言、恶意抹黑等创作歪风邪气,书写和记录这场举国上下同仇敌忾的疫情防控阻击的人民战争,彰显中国人民“坚定信心、同舟共济、科学防治、精准施策”“同时间赛跑、与病魔较量,坚决遏制疫情蔓延势头,坚决打赢疫情防控阻击战”的中国精神,为国家抗疫奉献艺术力量。

④人本,即以人为本,把人民生命安全和身体健康放在第一位。

这次疫情来势凶猛、波及面广,直接影响到每个人的生命安全。

艺术触角须与生命关怀、人性美善融入,才可能发现患者、医护人员、志愿者以及隔离在家中普通老百姓的生存状态和思想情绪,尤其是对逝者及其家庭成员的情感抚慰和精神激励,是文艺搭建安抚疏通渠道和体现人道情怀的特殊价值所在。

“抗疫文艺”创作应以人民群众利益为重,关心群众疾苦,通过“抗疫文艺”特有的感染力影响力,做到知民情、解民忧、纾民怨、暖民心,凝聚起全民族众志成城抗疫情的磅礴力量。
