2020年成都七中高三英语上学期期中考试试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AOne day when I was 5, my mother blamed me for not finishing my rice and I got angry. I wanted to play outside and not to be made to finish eating my old rice. When angrily opening the screen door (纱门) with my foot, I kicked back about a 12-inch part of the lower left hand corner of the new screen door. But I had no regret, for I was happy to be playing in the backyard with my toys.Today, I know if my child had done what I did, I would have blamed my child, and told him about how expensive this new screen door was, and I would have delivered a spanking (打屁股) for it. However, my parents never said a word. They left the corner of the screen door pushed out, creating an opening, in the defense against unwanted insects.For years, every time I saw that corner of the screen, it would constantly make me think about my mistake. For years, I knew that everyone in my family would see that hole and remember who did it. For years, every time I saw a fly buzzing (嗡嗡) in the kitchen, I would wonder if it came in through the hole that I had created with my angry foot. Iwould wonder if my family members were thinking the same thing, silently blaming me every time a flying insect entered our home, making life more terrible for us all. My parents taught me a valuable lesson, one that a spanking or stern (严厉的) words perhapscould not deliver. Their silent punishment for what I had done delivered a hundred stern messages to me. Above all, it has helped me become a more patient person and not burst out so easily.1. When the author damaged the door, his parents _______.A. gave him a spankingB. left the door unrepairedC. told him how expensive it wasD. blamed him for what he had done2. The experience may cause the author _______.A. not to go against his parents’ willB. to have a better control of himselfC. not to make mistakes in the futureD. to hide his anger away from others3. What is the main idea of this text?A. Parents is the best way to solve problems.B. Parents are the best teachers of their children.C. Adults should ignore their children’s bad behavior.D. Silent punishment may have a better effect on educating people.BIn Australia, plenty of wild things can bite or sting(刺伤) you. Strangely enough, one of them is a tree. Now scientists have figured out what makes the tree’s sting so bad.The rainforests of eastern Australia are home to a stinging tree known as Dendrocnide. Many people callit the gympie-gympie tree—a name given to the tree by native Australians. It’s covered with sharp, needle-like hairs that carry poison. If you touch a gympie-gympie tree, you won’t forget it anytime soon. The pain can stay with you for hours, days or weeks. In some cases, it’s been reported to stay for months.Scientists have long looked for the source of this powerful sting. Now researchers at the University of Queensland have discovered what makes this stinging plant so painful. After carefully studying different kinds of gympie-gympie trees, the scientists were able to separate out different chemicals that the trees produce. This allowed them to identify a group of chemicals that they believed was responsible for the pain.The researchers created artificial versions of these chemicals, which they call “gympietides”. Sure enough, when the scientists injected mice with gympietides, the mice licked(舔) at the places where they’d been injected, indicating that they hurt in those places. When the scientists studied the way gympietides were built, they found that they formed a knot-like shape. The shape makes the chemicals very stable, which helps explain why the pain stays so long.The knot-like shape of the gympietides was similar to the shape of poisons produced by poisonous spiders and cone snails. The scientists were surprised to see three very different kinds of life all using similar poisons. Spiders and cone snails carry poisons because they catch food by stinging other creatures. It’s not clear how stinging helps the gympie-gympie tree.Though the tree’s sting may stop some animals from eating it, it doesn’t stop all animals. Beetles and pademelons (small s of the kangaroo) are able to eat the plant without trouble.4. Why is a touch on the stinging tree unforgettable?A. Because it has so unusual an appearance.B. Because it is extremely rare in existence.C. Because touching it creates a quite strange feeling.D. Because the pain caused by it doesn’t go away quickly.5. What do scientists fail to find out about the stinging tree?A. How it produces poisons.B. What poisons it produces.C. How it benefits from the sting.D. The consequences of its sting.6. What does the text imply about the stinging tree?A. It produces the same poisons as spiders.B. Poisonous as it is, it also has natural enemies.C. Animals are wise enough to stay away from it.D. Only one chemical in it causes pain to the toucher.7. What’s the best title for the text?A. Scientists Discover Stinging Tree's SecretB. Caution: Stinging Tree Can Bite and Poison YouC. Scientists Discover a Strange Species in AustraliaD. Effective Ways to Avoid Being Hurt by Stinging TreeCIn the Hollywood industry, most of the studios are using AI to make movies for various reasons such as getting the actors out of danger, replacing the actors indifferent scenes, forming appealing atmosphere to enhance（增强）the views, etc.Directors and producers are using VFX (Visual effects), animations and AI to makea model that looks like the actor and replaces the actor's place. In particular, AI is used in scenes where actor shave to produce certain stunts （特技）to develop setups in the studio artificially. VFX is used to later change the internal studio backgroundsto a different place in the movie.There are many movies with two characters of the same actor. When AI was not a part of the film, editors used different methods to show the two aspects of the same actor in one scene, but now AI is being used to form the second character of the same actor and is being performed to the viewers.By a perfect combination of animation, VFX and AI, realistic models are being created. And the most fun part is the fictitious character can hold the face of the actor but the age, hairstyles, and clothing can be changed to create more enhanced looks according to the movie scene and story. With the help of AI, the directors recreating appealing scenes to enhance the thrill and excitement. InJurassic Park,no dinosaurs were running but with the help of AI and visual effects, we could enjoy the scenes and the atmospheres.The directors and the producers direct to form a green screen including the obstacles and those green screens get replaced with the views that are made from AI and VFX, and the actors make the scenes alive and deliver the most suitable action-packed movie scenes. This method also enhances the viewers' experience, which makes the movie a blockbuster（大片）.8. What does the author intend to tell us in paragraph 1?A. How AI helps actors.B. What AI brings to movies.C. Why AI is applied to movies.D. Where AI is made full use of.9. What can we infer from paragraph 3?A. AI can be used as an editor.B. Editors consider AI irreplaceable.C. Editors used many methods to replace AI.D. AI makes what used to be complex scenes easier.10. What's the author's attitude to using VFX, animations and AI in movies?A. Supportive.B. Sceptical.C. Unconcerned.D. Enthusiastic.11. Which of the following could be the best title for thetext?A. What AI Brings Out Hollywood MoviesB. Why AI Is Applied to Hollywood MoviesC. Which Hollywood Movies Make Much Use of AID. How AI Is Being Applied to Hollywood MoviesDA Chinese space mining company has designed a robot that can capture waste material left behind by spacecraft in outer space with a big net.The state-run Xinhua news agency recently reported that the robot launched on the government's Long March 6 rocket along with several satellites. The robot will also investigate deep space to observe small objects in the universe. The 30-kilogram robot, called NEO-01 , was developed by Origin Space. Pounded in 2019 and based in the southern Chinese tech hub(技术中心)Shenzhen, Origin Space has been devoted to exploring and using space resources, according to the company. The company says the robot will lead the way for future technologies capable of mining on asteroids(小行星).The world's first asteroid mining company, Planetary Resources, was established in 2009. Since then, more than 12 businesses around the world have entered the industry, including 3D Systems of the United States and Japan's Astroscale. Astroscale's technology uses magnets (磁铁)to gather up space waste. But a report on the Origin Space website says NEO-01 will use a net to capture waste and then bum it. Thousands of satellites havebeen launched worldwide. As they are used too long, many end up as waste and put other operating satellites at risk.Su Meng is the founder of Origin Space. He said the company plans to launch many space telescopes and more spacecraft to begin the first for-profit mining of asteroids by 2045. Su added that NEO-01 will serve as a prototype (雏形)of future space mining robots, which can use rich mineral resources on asteroids to support the development of the space industry.The Xinhua news agency reported that China was increasing efforts to land a spacecraft on a near-Earth asteroid to collectmaterials. China is also speeding up a plan to build a defense system against near-Earth asteroids. The country aims to follow Russia and the United States in becoming a major space power by 2030.12. Which of the following can correctly describe NEO-01?A. It weighs 60 kilograms.B. It was created by Planetary Resources.C. It will be burnt after finishing its mission.D. It is mainly used to catch space waste.13. What can be inferred from the text?A. China will be the most powerful in space by 2030.B. Origin Space will open more mines on asteroids.C. It is those useless satellites that make space waste.D. The robot will look into deep space for more waste.14. What does Su Meng think of NEO-01 ?A. It is promising and rewarding.B. It has benefited the space industry.C. It's a long way to produce it.D. It'll help make money for the company.15. What can be the best title for the text?A. NEO-01 , A Smart Robot Used in SpaceB.

During this time, mobile phones have been the solution for the boredom and restlessness caused from staying indoors. The most downloaded apps on play store 2020 are;TikTokTikTok was the most downloaded app. With over 111.9 million downloads, TikTok has seen a huge growth in 2020, twice more than what it got in 2019. 20% of its total downloads were fromIndiaand around 9. 3% of the total downloads were in theUS.ZoomZoom was the second most installed app in the overall downloads category. With nearly 94. 6 million installs, Zoom is the most used app for online meetings and virtual classrooms. 17% of its downloads were in theUSandIndia.

Which app is the best to turn to for online education?A. TikTok.B. Zoom.C. WhatsApp.D. Facebook.3. What function does Facebook probably serve?A. Communication.B. Training.C. Teaching.D. PaymentBIn the world of Chinese archaeology(考古学), a sign of a dig's importance is the sight of Zhou Mingsheng at work. A field technician who has worked at archaeological sites all aroundChina. Master Zhou iscredited with the gentlest touch in his profession. Born into a farming family, he is a “national-level craftsman” with a talent for using simple tools to get relics(遗物) that wouldcrumblein other hands, says his current boss, Wang Xu, director of an archaeological site at Shuanghuaishu, a Neolithic(新石器时代的) settlement near the Yellow River in the central province of Henan.It is not beauty that attracts visitors to Shuanghuaishu. At 5,300 years old, the settlement is the work of a culture too simple to have left behind many buried treasures. The single most precious find, to date, is a finger-length sculpture of a silkworm. Nor is the setting lovely: an area surrounded by deafening insects, between a highway and two power stations. Rather, the site's importance is historical. For since the birth of Chinese archaeology in the 1920s, it has been inseparable from claims thatChinahas the oldest unbroken civilisation on Earth.Leading archaeologists say that the site has the right combination of location, age and distinctive cultural elements to be the capital of an early Chinese kingdom. That would make it a bridge betweenChina's written history and the era of the Yellow Emperor, who is said to rule over these central plains almost 5,000 years ago, though many foreign scholars doubt his existence. Chinese media call the site proof ofChina's 5,000 years of history.Foreigners complain about a lack of written records, Mr. Wang notes. Perhaps they are missing symbols that will one day be understood, for instance in patterned pottery. Outsiders “can't keep using Western standards to apply to Chinese ruins,” he argues.4. What does the underlined word “crumble” in Paragraph 1 mean?A. Break.B. Start.C. Wait.D. Shine.5. Why does Shuanghuaishu attract visitors?A. It has appealing scenery.B. It has various precious treasures.C. It is of great historical significance.D. It is easily accessible.6. What is Mr. Wang's attitude towards foreigners’ view?A. Unconcern.B. Disapproving.C. Supportive.D. Not mentioned.7. What does the passage mainly talk about?A. Chinese history amazes the world.B. Chinese archaeology catches on.C. China follows its tradition.D.Chinadigs its past.CThe annual 3-to-4-millimeter rise in sea levels is expected to impact many coastal communities in the coming decades. However, few are as defenceless as the Republic of theMaldives, a collection of more than a thousand picturesque islands in theIndian Ocean. NASA researchers believe that parts of what is “arguably the lowest-lying country in the world” will become uninhabitable by 2050, due to wave-driven flooding and limited freshwater. To fight the unavoidable, the government recently revealed plans for the world's first 'true' floating island city.The aptly-named Maldives Floating City (MFC) is the brainchild of Dutch Docklands, a global leader in floating infrastructure (基建). According to the March 13, 2021, announcement, the new city will be constructed on a 200-hectare lagoon (环礁湖) located just 10 minutes by boat from the Maldivian capital, Male. It will initially consist of a thousand waterfront residences, arranged in a series of honeycomb-like maze rows. The developers plan to add hotels, restaurants, shops, and even a school and a hospital in the near future. The floating structures. will be attached to the surrounding islands, which will form a base and provide protection from high tides.Maldive officials aim to make MFC as self-sufficient as possible. Freshwater storage will provide drinking water for residents, while floating solar blankets and agriculture fields will take care of their energy and food needs.“ThisMaldivesFloatingCitydoes not require any land rehabilitation, therefore has a minimal impact on the coral reefs,” explains Mohamed Nasheed, Speaker of Parliament. “What's more, giant, new reefs will be grown to act as water breakers. In theMaldives,we cannot stop the waves, but we can rise with them.”Construction of the revolutionary city is expected to begin in 2022 and be completed in phases over the next five years. If successful, it will provide a blueprint for other countries facing a similar situation.8. Why doesMaldivesdecide to build MFC?A. It is the lowest-lying country.B. It will be flooded soon.C. It is running out of fresh water.D. It will be unsuitable for living.9. What is Paragraph 2 mainly about?A. The prospect of MFC.B. The developers of the plan.C. The location of the residences.D. The barriers to the construction.10. What can we infer from the underlined words?A. MFC will keep waves away.B. MFC will make use of waves.C. MFC will adjust to the waves.D. MFC will work as water breakers.11. What's the writing purpose of this passage?A. To introduce a construction program.B. To appeal to people to protect nature.C. To seek international help forMaldives.D. To report the achievement of a city plan,DMany of us in China enjoy adding chilies (辣椒) toour food, but did you know that this spicy vegetable could also be dangerous? A 34-year-oldUSman recently ended up in hospital after eating a Carolina Reaper—the spiciest chili in the world. After taking just a single bite of one, the man suffered from serious headaches in the following few days, reported BBC News.In fact, reports of stomachache and headache caused by eating spicy food are not something unusual. But if chilies are harmful, why is it that human beings are the only animals to eat this vegetable? According to the website Huanqiu, about 600 million Chinese people—almost half of the national population—are chili eaters. So what makes people love chilies so much? The human body reacts to the burning feeling that comes from eating chilies by releasing natural chemicals that “produce a sense of happiness” , noted BBC News.And the benefits go even further than just personal enjoyment. A survey conducted by the Chinese Academy of Medical Sciences found that the death rate of those who eat spicy food once or twice a week is 10 percent lower than those who eat it less than once a week. The number decreased to 14 percent for those who eat spicy food six to seven times a week. And another study done by theUniversityofVermontcame to a similar conclusion. “The data encourages people to eat more spicy food to improve health and reduce death risk at an early age,” Liu Qi, a nutritionist at the Harvard TH Chan School of Public Health, told BBC News.Chilies have anti-cancer quality and the ability to increase our metabolism (新陈代谢). So, don't worry if you love spicy food. It seems that chilies are actually good for us—except for the Carolina Reaper, perhaps.12. The example of a 34-year-old American is mentioned in Paragraph 1 to prove ________.A. chiliescan be beneficialB. chilies are popular inAmericaC. chilies can be dangerousD. serious headaches can be dangerous13. Eating chilies gives people a sense of happiness by_______.A. decreasing death rateB. releasing natural chemicalsC. curing serious headachesD. providing enough nutrition14. Which of the following statement is TRUE?A. Human are the only animals to eat chilies.B. Stomachache and headaches caused by chilies is something unusual.C. The more chilies you eat, the healthier you are.D. Chilies have anti-cancer quality but it can't increase our metabolism.15. The writer wrote the passage to ________.A. warn people of the dangers of chiliesB. ask people to eat Carolina ReaperC. encourage people to eat more chiliesD. tell people the benefits of chilies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。

These must-see bridges are now tourist attractions in their own right.Clifton Suspension Bridge, BristolDescribed byits legendary engineer Isambard Kingdom Brunel as “my first love, my darling”, in was originally designed for horse-drawn traffic. Now, more than four million vehicles a year cross the 1,352ft-Jong toll (收费) bridge over the Avon Gorge. The £ l toll for every journey pays for its repair. The history of the bridge, dating back to 1864, is kept alive through a programme of tours, events and exhibitions.Infinity Bridge, Stockton-On-TeesA pedestrian and cycle footbridge across the River Tees, its working title was the North Shore Footbridge, before it was given its grander name when opened in 2009. It is particularly spectacular (壮观) at night. The arches of the bridge are also lit white and, on calm nights, their reflection in the water appears as an infinity symbol, thereby inspiring the name which was chosen by the public.Tower Bridge, LondonAn engineering wonder built from thousands of tons of Cornish granite, Portland stone and steel, it took construction workers eight years to complete. More than 120 years old, it's a popular tourist attraction, as well as a functional bridge. Visitors can take in the views over the capital and experience seeing London life through the Glass Floor.Iron Bridge, ShropshireOpened in 1781, this is the first arch bridge in the world to be made out of cast iron. Recognised as one of the great symbols of the industrial revolution, it transformed the cart of bridge building and was a crucial factor in the development of the iron trade in Shropshire.1.Which bridge has the longest history?A.Clifton Suspension Bridge.B.Infinity Bridge.C.Tower Bridge.D.Iron Bridge.2.What can we know about Infinity Bridge?A.People can just walk on it.B.The public give it two names.C.It's well worth visiting at night.D.It's arch is the biggest on the earth.3.What do Clifton Suspension Bridge and Tower Bridge have in common?A.They are both over 120 years old.B.Visitors should pay for passing them.C.They have the same original design.D.Visitors can have a good view of London on them.BResearchers say spicy tomatoes could soon be on the menu thanks to the rise of gene-editing technology.It's not the first time that experts have claimed techniques could develop fruit with unusual features: scientists have already been looking at changing the color1 of kiwi fruit and bettering the taste of strawberries.But researchers inBrazilandIrelandsay such methods could also offer practical advantages, with hot tomatoes offering a new way of harvesting the pungent chemicals found in peppers known as capsaicinoids, which make food taste “hot”.“Capsaicinoids are valuable. They are used as painkillers and there are some researches showing that they promote weight loss,” said Agustin Zsogon from a Brazilian university, a co-author of a new article arguing for the benefits of engineering hot tomatoes.Writing in the journal Trends in Plant Science, the researchers say peppers are difficult crops to grow and low productive. Worse still, it is tricky to keep the pungency of the fruits table. By contrast, tomato production is high and the plant is well-studied. “You could produce the capsaicinoids in a more cost-effective manner,” said Zsogon.Tomatoes and peppers developed from a common ancestor, but separated about 19 million years ago. “All these genes to produce capsaicinoids exist in the tomato, they are just not active,” said Zsogon. “Using gene-editing technology, it is likely to switch these genes back on in tomatoes, making the fruit more special”, he said.4. Why are the tomatoes made hot by the researchers?A. To test the gene-editing technologyB. To improve the amount of the tomatoesC. To explore ways to harvest more capsaicinoids.D. To make the tomatoes more delicious.5. For what purpose can capsaicinoids be used according to the text?A. To put on weight.B. To ease the pain.C. To improve sleep.D. To better the look.6. What is Zsogon's attitude to the gene-editing technology?A. Confident.B. Critical.C. Anxious.D. Doubtful.7. What's the main idea of the text?A. An introduction to gene-editing plants.B. Creating hot tomatoes by gene-editing.C. Problems with capsaicinoid production.D. The procedure of producing capsaicinoids.CAs every mobile-phone owner knows, after a year or so the battery starts to fade and the beast needs recharging more frequently.That is troublesome, but a phone’s batteries can be replaced fairly cheaply — or the whole device traded in for the latest model. An electric car, though, is a much bigger investment. And batteries are its priciest component, representing around 30% of an average mid-size vehicle.To provide buyers with some peace of mind, carmakers guarantee their batteries, typically for eight years or around 200,000km. Producers, planning to go much further than that, though, are racing to launch “million mile”(1.6m kilometers) batteries. Contemporary Amperex Technology, a giant Chinese firm which produces batteries fora number of carmakers, was said to be ready to start producing batteries which would last for 16 years or 2m kilometres. Elon Musk has suggested that Tesla,a Californian maker of electric vehicles, has a million-mile battery in the works. And over in Detroit,General Motors is in the final stages of developing an advanced battery which it says has similar longevity (寿命)。

Nextdoor，with its ability to introduce neighbors to each other，helps people regain the sense of connection，he said.Early next year，Nextdoor plans to expand to Canada，followed by Great Britain，Australia，and South Africa，chief executive NiravTolia said. While Nextdoor has not yet have made any profit after two years of operations，Tolia said he is not worried.“If we look at the great companies at this stage，none of them started to monetize this early in theirevolution. ”Tolia said. “It’s all about getting the product right. ”Eventually，Nextdoor plans to tap into local advertising，he said.Nextdoor is currently used in 22，527 neighborhoods across the United States，up from 5，694 a year ago. Including the latest funding round，it has raised just over $100 million.4. What attitude do the early backers of technology grant hold towards Nextdoor?A. They doubt its value.B.

How does Nirav Tolia feel about the future of Nextdoor?A. Curious.B. Upset.C. Cautious.D. Optimistic.C"Sorry, but I don't agree with you..."This is usually followed by unbearable silence and angry tears. I've always found it difficult to disagree with someone, because I don't want to lose a friend. I've found it even harder to accept it when someone disagrees with me, because my ego（自尊心）ishurt.Before the other person gets a chance to explain why she disagrees with me, my usual response would be," If you aren't able to see my point of view, then what you think isn't worth my time or consideration, either." But now I've come to realize that when a friend disagrees with me, sometimes she is simply saying, "I don't agree with the way things are done." She still respects me as a person, and is only pointing out a better way to look at a matter. However, there may be times when my friend disagrees with me because I'm against the truth. That's when need to listen to what she says.I've learned that one way to help my friend is for me to be open and honest with the other to voice mythoughts and listen to the other carefully. While we can't control how a person will respond to our views, we must learn to disagree with our friends in love. We will never feel that we are better than the other person.And that will help us to be less emotional, and more objective in the way we express our opinions.In the same way, we can also stay open to feedback（反馈）from others,knowing that our friends may be correcting us in love.Good friendships build each other up, sometimes through disagreements and honest opinions. Though I don't like being disagreed with, I'm starting to see the value of such disagreements.8.

How to deal with disagreements.DRecycling plastic has always been a stop-start effort, and the wide variety of plastics we produce, the pollution from waste, and other limitations make recycling an economic(经济) problem. It’s estimated(估计)only 9% of plastic ever created has been recycled. But with the help of a chemical process, Canadian Miranda Wang and her company BioCellection want to change that.Stability is one of plastic greatest qualities and downside. There's limited evidence that some plastics can biodegrade (生物降解)but largely photo-plastics degrade in the sun. It’s a long process, and the truth is that we can only estimate how long it takes. Wang is looking to break the inaction and BioCellection's task is to make most plastic waste recyclable.She outlines two current methods. One is to take plastics like water bottles, wash them, cut them, melt and reconstitute them. “That's a very limited process” she says, due to the requirement that plastics be “clean” . The other, which can handle dirtier plastics and a level of pollution, is called hydrolysis(热解). Intense heat is applied tobreak down plastics so they can be reused as oils for energy, but “it’s not economical,’’ she says.BioCellection’s solution builds on research from over ten years ago, Wang explains, when a US studydiscovered pure polyethylene powder (聚乙烯粉)could be broken down by a catalyst (催化剂). Wang and her co-founder Jean hit upon a bacterium being able to eat plastic. In the years since, they engineered a comparable catalyst capable of doing the same job, only faster, which even works on plastics no one else can recycle at present. “We have now found a catalyst that is much cheaper than the one that was used before, Wang says.Currently focusing on plastic films like shopping hags, the three-hour process breaks clown plastic into chemicals that can act as the building blocks for more complex plastic products.“Right now we’re able to achieve about 70% transformation from plastic waste material to these chemicals,” she adds, saying they’re working to increase that figure.12. Why has so little plastic been recycled?A. Plastic is chemically stable.B. Recycling plastic led to pollution.C. We produced various plastics.D. Most photo-plastics degrade in the sun.13. What does Wang think of the two current methods?A. Highly effective and dynamic.B. Expensive and pollution-causing.C. Limited and energy-consuming.D. Widely used and recognized.14. What did BioCellection find effective to recycle plastics?A. Polyethylene powder.B. Chemical products.C. Plastic films.D. A catalyst.15. What is the text mainly about?A. Miranda Wang and her company.B. A new plastic recycling method.C. The greatest downside of plastic.D. Transformation of plastic waste.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2020届成都市第七中学高三英语上学期期中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ABook reading is certainly one of the most absorbing habits. For young adults who love to read, finding some good books to read is very essential. Writing a book review can help you to improve your language and writing skills.The Book ThiefListed onThe New York Times Children’s Best Seller List for over 100 weeks, The Book Thief by Markus Zusak is the story of a young girl in the Nazi camps set during World War II. So, if you love history and wish to learn how the life was during Adolf Hitler’s time, read this historic book.The Diary of Young GirlEven Anne Frank can not have imagined that her personal diary written during World War II would become such a popular book. It’s a must read that describes the situation of a family in the evils of wars through the eyes of a teenager.Animal FarmAnimal Farm is one of the most popular books by George Orwell. It is just a reflection of the Stalin and World War II period that has been so creatively presented in this book. It is an interesting example of how literature can be used to present conditions common in the society.Adventures of Huckleberry FinnMark Twain’s Adventures of Huckleberry Finn is one of the great American novels in history, and is certainly a great pick for young adults. Young Huck Finn and his mischief along with the color1 ful description of people around theMississippi Rivermake this novel a great book to read.1.Which book describes the author’s own experiences according to this passage?A.The Book ThiefB.The Diary of Young GirlC.Animal FarmD.Adventures of Huckleberry Finn2.What do the first three books have in common?A.All of them are about wars.B.All of them are about farms.C.All of them are intended for history lovers.D.All of them were written during World War II.3.The purpose of this passage is to _________.A.instruct youngsters how to improve skillsB.tell youngsters some wonderful reading habitsC.introduce several good books to youngstersD.give youngsters advice on writing a book reviewBAddiction to smartphones will result in poor sleep, according to a new study.The study, published Tuesday in Frontiers in Psychiatry, looked at smartphone use among 1,043 students between the ages of 18 and 30at King's College London. Researchers asked the students to complete two questionnaires on their sleep quality and smartphone use, in person and online.Using a 10-question scale that was developed to judge smartphone addiction in children, nearly 40% of the university students qualified as "addicted" to smartphones, the study found. “Our findings are in agreement with other reported studies in young adult populations globally, which are in the range of 30-45%,” lead author Sei Yon Sohn and her co-authors wrote in the study. "Later time of use was also significantly connected with smartphone addiction, with use after 1 a.m. increasing a 3- times risk," the authors wrote.Students who reported high use of smartphones also reported poor sleep quality, the study found. That foils in line with previous studies that have found overuse of smartphones at night to be associated with trouble falling asleep, reduced sleep duration (睡眠持续时间)and daytime tiredness. That's likely because use of smartphones close to bedtime has been shown to delay the body's normal sleep - and - wake clock.In fact, the No. 1 rule is "no computers, cell phones, and ipads in bed and at least one hour beforebed Dr. Vsevolod Polotsky, who directs sleep basic research, said in a recent interview. That's because "any LED light source from electronics (电子设备)may further hold back melatonin (褪黑激素)levels," Polotsky said. Melatonin is often referred to as a "sleep hormone," because we sleep better during the night when levels reach the top.“This is a cross-sectional study, and it cannot lead to any firm conclusions about smartphone use as the cause of reduced sleep quality, said Bob Patton, a lecturer in clinical psychology at the University of Surrey, via email.4. How did Sei Yon Sohn's team begin their study?A. By publishing researching papers.B. By responding to others’ concern.C. By collecting firsthand data.D. By turning to related experts.5. What did the study find about sleep quality and smartphone use?A. 30-45% of the university students are addicted to smartphones.B. High use of smartphones is related to poor sleep quality.C. Overuse of smartphones leads to shorter sleep duration.D. Use after 1 a.m. will result in smartphone addiction.6. What is Polotsky's opinion on electronics ?A. We should stop using them an hour before going to sleep.B. LED light source from them will delay normal sleep- and- wake clock.C. Reduced sleep quality has nothingto do with them.D. No electronics should be used in bed at any time.7. What can be a suitable title for the text?A. Say No to SmartphonesB. Sleep Quality Can Be ImprovedC. LED Light Source Causes Great HarmD. Smartphone Addiction Ruins SleepCScientists have recently discovered thatAndean condors (秀鹫)— some of the world’s largest birds——barely flap their wings at all while flying. Instead, they use rising air currents to remain in the air for hours.The Andean condor is the world’s largest soaring bird. They can weigh up to 15 kilograms. Their wings, when spread out, measure up to three meters. Their main food source is the meat of large animals which have died. Soaring high in the sky allows condors to easily spot possible meals on the ground.Scientists worked together to study the flight patterns of these huge birds and how much effort the birds use when flying. To study the birds while they were in the sky, the researchers attached special devices which could record every beat of their wings.The scientists learned that most of the condors’ flapping— over 75%— came when the birds were taking off. Once in the sky, the birds flew for very long periods of time without flapping at all. In fact, they only flapped their wings for 1% of the time they were in the air. One bird flew for over five hours without flapping, covering nearly 117miles.Soaring without flapping is important because birds bum energy every time they flap their wings.The birds’ soaring isn’t magic. They use the fact that hot air rises to keep themselves up. As hot air rises, itoften creates “thermals”— currents of warm air moving upward. The condors soar by making use of these thermals. The tricky part is finding thermals and moving between them.When birds are forced to land and take off again often, it costs them a lot of energy. The researchers learned that to avoid having to land, the condors did most of their non-take-off flapping when they were closer to the ground and looking for a new thermal.The scientists reported that even though all of the condors they studied were young, they knew well how to take advantage of the air currents.8. What can we learn about the Andean condor from the text?A. They live mairly on small animals.B. Their wingspan is at least three meters.C. They rely on hot air to remain high in the sky.D. They are the birds with the strongest flying ability.9. Why was the equipment tied to the birds?A. To measure how far they could fly without flapping.B. To keep track of how often they flapped while flying.C. To calculate the energy required for their flight.D. To confirm their flight patterns.10. Which of the following acts consumes the most energy for a condor?A. Hunting for food.B. Flying in the sky.C. Getting off the ground.D. Landing on the ground.11. What can we infer from the text?A. Condors flap the most when looking for a new thermal.B. No condor can fly for more than five hours without flapping.C. Condors don’t need to look for thermals when soaring in the sky.D. Soaring by using thermals is probably a natural ability of condors.DA world in which extinct creatures could be brought back to life came a step closer yesterday. Australian scientists have managed to extract a gene from a preserved sample of a Tasmanian tiger and make it active. Thebreakthroughhas left them dreaming that one day they will be able to recreate the animal, which died out more than 70 years ago. And if it can be done with the Tasmanian tiger, it may also be possible to resurrect (复活)creatures that have been extinct for far longer.“There used to be a time when extinction meant forever, but no more, ” said Professor Mike Archer. “We are now able to seriously challenge whether those animals that have gone for ever. What has been achieved is a very important step in bringing back those animals that are extinct. And while I think that technically it is still pretty difficult at the moment, we can now see the possibilities. I’m personally convinced that the Tasmanian tiger will be brought back to life in my lifetime.”The breakthrough came after nine years of experiments by scientists at the University of Melbourne, who extracted a gene from one of several tigers preserved in alcohol in a Melbourne museum. They removed the equivalent gene from a mouse embryo implanted the tiger gene and then watched as the mouse continued to grow normally, suggesting the tiger gene had been activated.Team leader Dr. Andrew Pask said it was the first time DNA from an extinct species had been used to “induce (引起) a functional response in another living organism”.However, the animal’s entire gene structure would have to be revived in the same way to even begin the possibility of bringing the Tasmanian tiger back from the dead.Mick Mooney, a wildlife officer ofthe Tasmanian Government, was worried that such developments could encourage people’s indifference to the protection of endangered species.“If people think that we can bring animals back to life after they’ve gone, they will start saying that there is nothing to worry about because we can fix it up later.”12. What does the underlined word “breakthrough” in the l paragraph refer to?A. Scientists have recreated new animals.B. Scientists have resurrected endangered animal.C. It has turned out that some creatures would not go extinct.D. A tiger gene has been extracted successfully and activated.13. Scientists are carrying out the experiments in order to ________.A. bring extinct animals back to lifeB. transplant the genes of tigers into other animalsC. find out what factors lead to the animals’ extinctionD. find a new way to extract animals’ DNA14. Mike Archer thinks that ________.A. scientists now have no technological difficulty reconnecting extinct animalsB. it’ll be a century or so before a Tasmanian tiger walks on the earth againC. humans have come closer in reconnecting extinct animalsD. reconnecting extinct animals is impossible15. We can learn from Mick Mooncy’s words that_________.A. he thought it unnecessary to worry about endangered animalsB. his opinion is in contrast with that of the Tasmanian GovernmentC. he thought people should be encouraged to protect endangered animalsD. he is concerned that bringing extinct animals back to life may have a negative effect第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2020届成都市第七中学高三英语上学期期中试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AI started working with my hands at a young age. The youngest of five brothers, I took on the role as a “maintenance (维修) man” at an early age for our family’s small grocery store. Often my dad wouldn’t give me a clear idea of how something shouldbe done, so I just had to figure it out by researching or through trial and error.Fast forward to 2016 and those problem-solving skills would become the focus of Tippecanoe High School’s Homebuilding class. I knew I wanted to teach the students skills that went beyond just being able to hammer nails or cut pieces of two-by-fours. The problem was that we didn’t have the resources at the time to do much else. The idea of attracting some type of funding seemed very important. Designing, building and selling a tiny house on wheels seemed like the perfect project to accomplishthe task. I reached out to a number of local businesses and most of them responded with the greatest support for what x k w we were doing.This year we added a new element to the program. Through one of our partners, we were able to connect with the nonprofit Veteran’s Ananda Incorporated. Students in the Homebuilding class are leading the design and production of micro houses to be donated to this organization. The new partnership gives the students another focus to consider when designing and building the houses.There has been no shortage of students since our first year. Three years ago we had 41 students, the next 191, and this year it was limited to just over 160 students so we could have a safe and manageable classroom environment. The number of girls taking the class has risen steadily over the last few years as well. This class offers something for everyone and the skills are universal.1. How can we describe the young author?A. He opened a small grocery store.B. He did a lot of research in the lab.C. He enjoyed doing hands-on activities.D. He learnt about maintenance from his father.2. What do the underlined words “the task” in paragraph 2 refer to?A. Getting some financial support.B. Selling a tiny house on wheels.C. Reaching out to many local businesses.D. Offering the students some problem-solving skills.3. What can be inferred about the Homebuilding class from the last paragraph?A. Its size needs increasing.B. Itis popular with the students.C. It has caused some safety concerns.D. Its classroom environment is hard to manage.BA 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 towalk 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.4. 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.5. Where did Jimmy meetNancyten years later?A. Near Jimmy’s high school.B. At a Mother’s Day tea.C. In Nancy’s classroom.D. On a field trip.6. How did Jimmy feel about whatNancyhad done for him?A. Upset.B. Embarrassed.C. Grateful.D. Satisfied.7. 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. A mother’s hug lasts long after she lets go.D. The best teacher must be the best performer.CA year ago I received a full scholarship to attend the University of San Francisco. All of my hard work paid off. My mom had spent a lot on my attending a private high school, so I made sure to push myself: I volunteered, took part in various clubs, and graduated with honors. I was so excited to start a new part of my life.Soon enough, the big day came, but it wasn't like what I had thought. The first two weeks were the most difficult days of my entire life. Every night I would cry myself to sleep. I was missing my family, my home and everything in my hometown so much and I didn’t know how to deal with my broken heart.To distract myself, I threw myself into my studies. I also found a ton of jobs. In any free time, I started forcingmyself to go to the gym. I wanted to keep every part of my day busy so I wouldn’t think about how lonely I felt. Soon after, I began to control my eating, considering it another solution to my homesickness. But soon there was something wrong with me.Finally, I went to see a doctor. When the doctor told me I had no choice but to take time away from school, I started to fear. How could I stop? School was what I was best at. “I’m not so bad,” I thought in my head. But the result was that I was taken to hospital again a month later and my mother camewoefully. I had to take a semester off from school, and go to the treatment center near my home.If there are girls who are suffering similarly, I hope you know that there is hope and that you should have a positive attitude towards life. Though you may feel alone, there are so many people who can understand your struggle. That’s why I want to share my story.8. Why did the author push herself during high school?A.

She couldn't catch up with others.10. What does the underlined word “woefully” in paragraph 4 mean?A. Sadly.B. Surprisingly.C. Curiously.D. Happily.11. What is the author's purpose in writing this text?A. To look back on her past life.B. To increase her own confidence.C. To express appreciation to her mother.D. To encourage other girls like her to be positive.DIt is a question people have been asking for ages. Is there a way to turn back the aging process?For centuries, people have been looking for a “fountain of youth”. The idea is that if you find a magical fountain, and drink from its waters, you will not age.Researchers in New York did not find an actual fountain of youth, but they may have found a way to turn backthe aging process. It appears the answer may be hidden right between your eyes, in an area called the hypothalamus (下丘脑). The hypothalamus is part of your brain. It controls important activities within the body.Researchers at New York’s Albert Einstein College of Medicine found that hypothalamus neural (神经的) stem cells also influence how fast aging takes place in the body.What are stem cells(干细胞)? They are simple cells that can develop into specialized cells, like blood or skin cells. Stem cells can also repair damaged tissues and organs.Dongsheng Cai is a professor at the Albert Einstein College of Medicine. He was the lead researcher in a study on aging in mice. He and his team reported their findings in the journal Nature, Cai explained when hypothalamus function is in decline, particularly the loss of hypothalamus stem cells, and this protection against the aging development is lost. it eventually leads to aging.Using this information, the researchers began trying to activate, or energize, the hypothalamus laboratory mice. They did this by injecting the animals with stem cells, Later, the researchers examined tissues and tested for changes in behavior. They looked for changes in the strength and coordination (协调) of the animals muscles. They also studied the social behavior and cognitive ability of the mice. The researchers say the results show that the treatment slowed aging in the animals, Cai says injecting middle-aged mice with stem cells from younger mice helped the older animals live longer.But these results were just from studying mice in a laboratory. If the mice can live longer, does that mean people could have longer lives? The next step is to see if the anti-aging effects also work in.12. In Paragraph 2 a “fountain of youth” is mentioned to ________.A. introduce the main topicB. show a hidden secret.C. describe scientists researchD. recommend a way to stay young13. Aging takes place in the body when _______.A. stem cells develop into specialized cellsB. there are important activities within the bodyC. hypothalamus neural stem cells fail to protect against agingD. the hypothalamus fails to repair damaged tissues and organs14. What do we know about the researchers at Albert Einstein College of Medicine from the text?A. They did experiments to see how stem cells work.B. They studied mice to find their connection with humans.C. They have found a possible way to slow the aging progress.D. They have found no changes in mice s behavior during the experiment15. What will the researchers probably do next?A. They will help some animals live longer.B. They will announce the fountain of youth doesn’t existC. They will develop products to help people live a longer life immediatelyD. They will do research to see if what they have found in mice will apply to humans.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2020届成都市第七中学高三英语上学期期中考试试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AThe following 4 famous paintings, from Jan van Eyck’s portrait to Pablo Picasso’s masterpiece, have stood the test of time.The Arnolfini PortraitJan van Eyck’s Arnolfini Portrait, an oil painting on wood produced in 1434, is undoubtedly one of the masterpieces in the National Gallery,London. This painting is as visually interesting as it is famed. It is also an informative document on fifteenth-century society, through van Eyck’s heavy use of symbolism-while husbands went out to engage in business, wives concerned themselves with domestic duties.The Starry NightVincent van Gogh painted The Starry Night, oil on canvas, a moderately abstract landscape painting of an expressive night sky over a small hillside village, during his 12-month stay at the mental hospital nearSaint-Remy-de-Provence,Francebetween 1889 and 1890. When theMuseumofModern ArtinNew York Citypurchased the painting from a private collector in 1941, it was not well known, but it has since become one of van Gogh's most famous works.The HarvestersThe Harvesters is an oil painting on wood completed by Pieter Bruegel the Elder in 1565. It depicts the harvest time which most commonly occurred within the months of August and September. Nicolaes Jonghelinck, a merchant banker and art collector fromAntwerp, commissioned this painting. The painting has been at the Metropolitan Museum of Art inNew York Citysince 1919.GuernicaGuernica,a large black-and-white oil painting, was painted by the Cubist Spanish painter, Pablo Picasso in 1937. The title ‘Guernica’ refers to the city that was bombed by Nazi planes during the Spanish Civil War. The painting depicts the horrors of war and as a result, has come to be an anti-war symbol and a reminder of the tragedies of war. Today, the painting is housed at the Museo National Centro de Arte ReinaSofiainMadrid.1. What do the four paintings have in common?A. They are oil paintings.B. They are kept inNew York.C. They show different people’s lives.D. They are created during 10th century to 19th century.2. What do we know about The Starry Night?A. It shows the scenery of a small hillside village.B. Van Gogh produced it when living in his home.C. A private collector gave it away to the museum.D. It was not famous before 1941.3. Whose painting shows the destruction of war?A. Jan van Eyck.B. Vincent van Gogh.C. Pieter Bruegel.D. Pablo Picasso.BThe term "bird brain" is frequently used to describe a person's lack of intelligence and good decision-making ability. However, some scientists believe it should be considered a praise, given that many birds can perform human tasks like producing and using tools, solving problems, and planning for future needs. Now,Griffin, an African Grey parrot, has proved that birds may even possess better visual memories than human adults and children.The study, led by Hrag Pailian, a researcher at Harvard University, had the parrot compete in the game against twenty-one undergraduate students and twenty-one 6 to 8-year-old children. The popular challenge involves hiding a small object under one of three or more upside-down cups, which are moved around. Participants are required to accurately identify the cup under which the object lies. To make the task more challenging, the researchers required participants to track two, three, and four objects at the same time.An analysis of the results showed thatGriffinoutperformed the 6 to 8-year-olds across all levels on average. Even more impressive, the "bird brain" performed as well as, or slightly better than, the 21 Harvard students on 12 of the 14 trials! It was only in the final two tests, which had the most objects and most movement, that the parrot fell behind the adults. However,Griffin's performance was never below that of the children.Griffinwas the candidate of choice because the scientists needed an animal that had a brain functionality similar to that of humans. "The fact that the smart parrot loves to show off his brain power in exchange for a few cashews (腰果) did not hurt either", said Irene Pepperberg, a Harvard lecturer, who has trained Griffin and several other African Grey parrots, has been studying the species for over four decades and is considered a pioneer in the study of bird intelligence.4. Whatwere the participants required to do in the study?A. Identify different kinds of objects.B. Tell where the hidden object lies.C. Track other participants' performance.D. Move around upside-down cups.5. What did the results of the study indicate?A. 6 to 8-year-olds did better thanGriffin.B. Parrots have a better memory than other birds.C. Harvard students have a better visual memory.D.Griffinoutsmarted Harvard students in some trials.6. Why wasGriffinchosen for the experiment?A. It was good at making decisions.B. It was specially trained for experiments.C. It had similar brain functions to human beings.D. It loved to show off his language power for some treats.7. What is the best title for the text?A. "Bird brain" becomes a term for a stupid person.B. Harvard lecturer pioneers in bird intelligence study.C. Parrot outsmarted Harvard students in visual memory test.D. Researchers made new discoveries about human intelligence.CParents and math teachers regularly asked by their school-aged charges whether math matters inreal life now have an answer.In a study published by the National Bureau of Economic Research this week, Harvard Kennedy School Policy Professor Joshua Goodman took a look at what happened to students whose high schools were required in the 1980s to increase the minimum level of coursework required to graduate. What he found is that the students were more likely to increase the number of math courses they took as a result of the change in standards and that translated into higher earnings down the line.Put simply: About 15 years after they graduated, the high school graduates who went to school when these changes took effect saw their average earnings increase about 10% for every extra year of math coursework. The findings may add fuel to the steady drum of education experts, policy makers and others calling for an increased focus on science and math education.The increase in required math courses didn’t necessarily produce rocket scientists, Goodman notes, becausethe extra coursework wasn’t at a particularly high level. But becoming familiar with and practicing ly basic math skills allowed high school graduates to pursue and excel at jobs that required some level of computational knowledge, he said.Goodman acknowledged that the earnings boost for the students connected with the up tick （上升）in math education may be dependent on the state of the economy. When Goodman checked in the late 1990s and early 2000s on the earnings of the students who graduated in the late 1985，he found that their earnings increased significantly if they took more math.8. What does Joshua Goodman’s study find?A. High school graduates earn more.B. High school students prefer math.C. Math matters a lot in one’s income.D. Math is a compulsory course in school.9. Why is increase in required math courses useful?A. It produced rocket scientists.B. It makes high school students smarter.C. It meets the requirements of the government.D. It enables high school graduates to get better jobs.10. What might be the author’s purpose in writing the text?A. To give a warning to policy makers.B. To seek help for high school students’ problems.C. To show the great importance of learning math.D. To tell a struggling history of high school students.11. What could be the best title for the text?A. Efforts matter mostB. Math makes moneyC. Earnings of different graduatesD. Changes of high school coursesDTexas has been one of the most restrictive gun-rights states in America.Thanks to a new law,however,the state will be one of the most relaxed,to the degree that police are discouraged from even asking about someone's guns.And if they do, they may not have much power to do anything if the person refuses to show a license.To be sure, the law is strict in its own way,offering a model for regulation. Under the law, open-carry citizens have to be licensed, a process that includes safety and shooting tests. They also have to show no prior psychological problems, and they have to be at least 21 years old.It is true that gun violence dropped sharply after restrictive laws were put in place in countries like Great Britain and Australia. However,the US public seems more interested than ever in weapons and the power they convey,despite gun control groups' concern over the increase of violence. Most states in America have steadily expanded gun rights since the end of a 10-year assault(攻击)weapons ban in 2004. Black Friday this year saw the biggest gun cache(贮存)ever purchased in one day.Considering those trends,there's a heated debate about whether the new Texas law is a model piece of legislation(立法)for a changing America,or a walking disaster just begging for trouble. As the law doesn't provide any punishment for those who refuse to show a license to a police officer, critics fear that officers may find it tough to handle potentially deadly situations. After all, armed citizens will no longer be considered suspicious, even though a lot of people might be alarmed by the sight. Most police in Texas have been told to not engage gun carriers unless they are doing something questionable or appear drunk.For sure,New Year's Day will be an exciting one for Texas gun owners. What's not yet known is how the rest of Texas will respond.12. All of the following are required in the new Texas law for open carry EXCEPTA. age limitB. mental conditionC. online registrationD. gun-operating skills13. What is mainly talked about in Paragraph 3?A. The reason for putting forward the new Texas law.B. The present situation of gun possession in America.C. The impact of the assault weapons ban in 2004.D. The inaction of the US government as to gun control.14. What do critics think the new Texas law will probably lead to?A. Heavier workload for policemen.B. Disrespect for officers.C. Lack of trust among citizens.D. Difficulty in crime prevention.15. What is the author's attitude towards the new Texas law?A. Negative.B. Cautious.C. Indifferent.D. Approving.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。

Now blind box toys are bringing the magic of surprise to online shopping.A blind box toy is hidden inside uniform packaging but invisible from the outside. You don’t know what will be inside, although the toys typically come from pop culture, ranging from movies to comics and cartoons.Blind boxes have caught on since they were first introduced fromJapantoChinain 2014. According to a 2019 Tmall report, the mini-series of Labubu blind box, designed byHong Kong-born Kasing Lung, was named Champion of Unit Sales with 55,000 sold in just 9 seconds during the Singles Day shopping event. Most customers for blind boxes are young people aged 18 to 35.According to The Paper, blind box toys are popular in part because of their cute appearances. The typically cute cartoon figurines come in miniature sizes, making them suitable for display almost anywhere.Even if blind boxes are not their top choice for decorations, the mystery and uncertainty of the process also attracts people. It’s the main reason why people buy blind boxes one after another.“Fear of the unknown is always a part of the box-opening process,” said Miss Cao, 24, who lives and works inShenyang. Speaking to Sina News, she said: “Until you open all the boxes, you cannot know what it is inside.”Opening a blind box is a delightful little surprise for our mundane daily lives, something small but fun to wait for each day, week or month. When people open this simple little box, they may be disappointed, but the uncertainty is part of the fun. People will open more blind boxes and hope for a better outcome.When someone re-makesForrest Gump, don't be surprised if he says, “Life is like a blind box...”1.

Eye doctors inBristolcared for the 17-year-old after his sight had gone to the point of blindness. Tests showed he had serious vitamin deficiency(缺乏). Dr. Denize Atan, who treated him at the hospital, said, “His diet was basically a portion of chips from the local fish and chip shop every day. He also used to snack on crisps and sometimes white bread and ham, and not really any fruit and vegetables.”The teenager saw his doctor at the age of 14 because he had been feeling tired and unwell. At that time he suffered from vitamin B12 deficiency, but he did not stick with the treatment or improve his poor diet. Three years later, he was taken to theBristolEyeHospitalbecause of progressive sight loss.He was not overweight or underweight, but he had lost minerals from his bones, which was really quite shocking for a boy of his age. In terms of his sight loss, he met the standards of being blind. “He had blind spots right in the middle of his sight,” said Dr Denize Atan, “That means he can’t drive and would find it reallyarduousto read, watch TV or recognize faces.”Dr Denize Atan said that parents should learn about the harm that can be caused by picky eating, and turn to experts for help. For those who are concerned , she advised, “It’s best not to be anxious about picky eating , and instead calmly introduce one or two new foods with every meal.” She said multivitamin tablets can supplement(补充) a diet, but cannot take the place of eating healthily. “It’s much better to take in vitamins through a varied and balanced diet,” she said, adding that too manycertain vitamins , including vitamin A, can be harmful ,“so you don’t want to overdo it.”4. What does Dr Denize Atan imply in paragraph 1?A. The diet of the boy is not balanced.B. Fruit and vegetables are rich in vitamins.C. Picky eating is common among teenagers.D. The cause of the boy’s disease is unknown.5. Why did the boy go to see his doctor at the age of 14?A. To improve his poor diet.B. To get some help to lose weight.C. To be treated for his discomfort.D. To slow down his progressive sight loss.6. What does the underlined word “arduous” in paragraph 3 probably mean?A. Important.B. Easy.C. Necessary.D. Difficult.7. What does the last paragraph mainly talk about?A. Reasons why the boy is seriously ill.B.Suggestions for the boy’s family to care for him.C. Advice for parents worried about picky eating.D. Waysof taking in enough vitamins and minerals.CChancellor of the Exchequer George Osborne said yesterday he would use the autumn spending review to increase Britain’s￡12bn-a-year aid budget towards humanitarian(人道主义的) causes in the wake of the European refugee(难民) crisis.Britainpromised to spend 0.7 percent of state general product on aid, meaning the budget could rise sharply by the end of the decade as the economy grows.Mr Osborne also said more of the aid budget could be given to help local government with housing costs for incomers, without breaking international guidelines.“We will use the foreign aid budget to help with the costs of these refugees. People ask about the pressure on public services; we’ll have extra money to help with that.”The government was unable to give a figure for how much aid money could be handed to local authorities: it would depend on how many refugees are accepted.David Cameron, Prime Minister, will set out his position on aid for refugees today. It is reported thatBritainwill accept at least 10,000 extra people from camps on theSyriaborder. He will use a statement in the House of Commons to flesh out plans — announced inMadridon Friday — to take more people.A report inThe Sunday Timesthat the UK would take 15,000 Syrians, not far from the 18,000 figure demanded by the EU, was described by “Downing Street” as a “guess”.TheUKwill offer to resettle Syrians directly from refugee camps inJordan,LebanonandTurkey— but not those who have already reached the EU.8. What is the main idea of the passage?A. Britain tried to help refugees.B. People doubtBritain’s kindness.C. Britain tried to explain its behavior.D. Refugees like to live inBritain.9. What can we infer from the first two paragraphs?A. Britain’s economy grows rapidly.B. Britain will use little of its money to help refugees.C. Most countries are not willing to help refugees.D.Britainwill use more money to help refugees.10. Which of the following statements is TRUE?A. Britain will use foreign money to help refugees.B. Britain helps refugees following international guidelines.C. Britain will use foreign money to develop themselves.D. People ask to use public service money to help refugees.11. What can we know from the passage?A. Britain can hold 10,000 refugees at most.B. The number of refugees to be received is uncertain.C. House of Commons declare a general plan.D.Britaincan hold 15,000 refugees at most.DA 10-year-old swimmer with sky-high dreams and a name to match them has broken a record previously held by Olympian Michael Phelps.Clark Kent Apuada, whose friends call him“Superman", swam the 100-meter butterfly in 1:09.38 at the Far Western Long Course Championships in his home state of California this Sunday. That's a second faster than the record Phelps set at the same event in 1995 with a time of 1: 10. 48 in the same category of boys under 10.Clark, a rising fifth-grader who is Filipino-American, told HuffPost he's been dreaming about breaking Phelps' record ever since he started swimming competitively at age 7."I was so motivated,"Clarksaid about his win."I was so happy that I was able to beat that record.”Phelps competed in his first Olympics at age 15. He went on to become the mostdecoratedOlympian inhistory, with 28 medals overall. “Everyone in the crowd was excited when they realized what a special swim they had just seen when we announced the long-standing record had been broken,"Cindy Rowland,Pacific Swimming's director, wrote in an email.Clarkwon first place for all the swimming events he competed in at this year's Far Western Championships. Pacific Swimming or PacSwim, a regional association that is part of USA Swimming, organizes the Far Western Long Course Championships. Cynthia Apuada,Clark' s mother,said that her child seems to be “living by his name at this point”。

2020年成都市第七中学高三英语期中考试试题及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ASome young people win attention because of their good looks or their singing ability. A much smaller number gain fame because they have done something important and worthwhile with their abilities. Rishab Jain is among the latter. In 2018, 13-year-oldRishab developed a way to use AI technology to help pancreatic(胰腺的) cancer patients and won the3MYoung Scientist Challenge, a nationwide middle-school science competition, and its $25,000 prize.In the last stage of the contest, Rishab competed againstnine other finalists at the 3M Innovation Center(创新中心) in St.Paul,Minnesota. Leading up to the big meet, each finalist had partnered with a scientist to further develop their inventions.Rishab explains what led him to create his invention. First,a family friend died of cancer. Then Rishab learned about how deadly pancreatic cancer is, and that its low survival rate is due to how difficult it is to treat. "I'm also into programming, so I was learning about AI technology. I decided to try to solve a real-world problem using it."His winnings have been put in further research and in his nonprofit Samyak Science Society, which helps poor children enter the STEM (science, technology, engineering and math) education. Rishab is also raising awareness about pancreatic cancer. These efforts make him quite different from teenagers of his age. Considering becoming a biomedical engineer or a doctor一or both, he has also put some money aside to further his own learning. Almost certainly the doors of higher education will open wide to him before he even knocks.That's an outstanding outlook for one so young. Rashib is committed to helping very sick people in need. He is also providing teenagers of his age with a much-needed model of what kinds of things youth can achieve.1. What can we learn about the 3M Young Scientist Challenge in 2018?A. It was intended to solve medical problems.B. It was a nationwide AI competition for teenagers.C. It offered the finalists an opportunity to work with scientists.D. It allowed the finalists to learn AI technology in the 3M center.2. How did Rishab win the 3M Young Scientist Challenge?A.He showed excellent programming ability.B. He figured out the survival rate of pancreatic cancer.C. He introduced poor children to STEM education.D. He applied AI technology to treating pancreatic cancer.3. Which of the following best describes Rishab?A. Talented and caring.B. Independent and humorous.C. Responsible and patient.D. Polite and inspiring.BMy sister Alice and I have been trying to get people tostop dropping cigarette（香烟）butts（烟头）for seven years. One day, we were walking in our hometown and saw hundreds of cigarette butts on the ground. They made the town look so ugly that we decided to start a group to make people dropping butts. We called it “No Butts About It”.At first, we drew pictures with “The Earth is not your ashtray（烟灰缸）”written on them. We put the pictures around our hometown—in parks, by beaches, and along roads. We wanted to make people understand that dropping butts hurts the environment. Most smokers don’t think that dropping butts hurts the Earth. But it does, and all rubbish does!Later, we wrote to companies and asked them for money to help us. We used the money to buy ashtrays to give to smokers. We wanted smokers to carry the ashtrays with them so they didn’t have to drop butts.At the moment, we are trying to get cigarette companies to put an ashtray in each pack of cigarettes. Some companies want to do it. Many people have started to join our group since it began. Today there are 45 other “No Butts About It” groups inAmerica.Now there even groups inEngland,Australia, andIndia! Many newspapers have written about my sister and me over the last seven years. And we have won many prizes for what we do. But we are not interested in prizes. We just want to make the Earth a better and cleaner place for animals, plants and people.One day, it will be.4. What did the writer think about the cigarette butts in the first place?A. They made the town smelly.B. They made the town unhealthy.C. They made the town dirty.D. They made the town poor.5. What does the writer do with the cigarette butts?A. Give ashtrays to the smokers.B. Stop people buying cigarettes.C. Pick up the cigarette butts.D. Win prizes for starting groups.6. From the passage we can know that _____.A. no companies wanted to give money to themB. The writer believes that the Earth will be a better and cleaner placeC. There are only 45”No Butts About It”D. The writer likes to be on newspapers and win prizes27. Which is the best tittle for the passage?A. Save our Town From Cigarette Butts.B. Buy Yourself An Ashtray.C. Cigarette Butts Also Destroy Other Countries.D. No Butts Prize.CI don’t think I can recall a time whenI wasn’t aware of the beauty of the ocean. Growing up inAustralia, I had the good fortune of having the sea at my side. The first time I went toHalfmoonBay,I suddenly had the feeling of not being able to feel the ground with my feet anymore.For my 10th birthday, my sister and I were taken out to theGreat Barrier Reef. There were fish in different color1 s, caves and layers of coral. They made such an impression on me. When I learned that only one percent ofAustralia’sCoral Seawas protected, I was shocked. Australian marine (海洋的) life is particularly important because the reefs have more marine species than any other country on earth. But sadly, only 45% of the world’s reefs are considered healthy.This statistic is depressing, so it’s important for usto do everything to protect them. The hope that theCoral Searemains a complete ecosystem has led me to take action. I’ve become involved with the Protect Our Coral Sea activity, which aims to create the largest marine park in the world. It would serve as a place where the ocean’s species will all have a safe place forever.Together, Angus and I created a little video and we hope it will inspire people to be part of the movement. Angus also shares many beautiful childhood memories of the ocean as a young boy, who grew up sailing, admiring the beauty of the ocean, and trying to find the secrets of ocean species.8. What can we learn about the author from the underlined sentence inPara. 1?A. He seldom went surfing at the sea.B. He forgot his experiences about the ocean.C. He never went back to his hometown.D. He had a wonderful impression ofHalfmoonBay.9. What is Australian marine life like according to the second paragraph?A. It is escaping from theCoral Seagradually.B. It depends on reefs for living greatly.C. It may be faced with danger.D. It is protected better than that in other oceans.10. What’s the purpose of The Protect Our Coral Sea activity?A. It is intended to contribute to a complete ecosystem.B. It is intended to prevent more marine species being endangered.C. It is intended to set up a large nature reserve for reefs.D. It is intended to raise more teenagers’ environmental awareness.11. Why do Angus and the author create a little video?A. To urge more people to take action toprotect the marine species.B. To inspire more people to explore the secret of the ocean.C. To share their childhood experiences about the ocean.D. To bring back to people their memory of ocean species.DOne-year-old Tallulah turned purple and stopped moving after the sweet became stuck in her throat. Her mum Leigh-Anne said the drama began during a visit to her grandma’s house when her grandparents gave her older kids some sweets.“Then at about 4:45 pm, Tallulah started to choke—we all went into a panic.”“It seemed like it went on for ages. Not one of us knew what to do.”“I rang an ambulance while my grandma and granddad tried to get the sweet to come up.”“Tallulah was panicking at first but then she started to go purple—she almost had no oxygen left in her.”With her daughter limp (无力的) and time running out, Leigh—Anne knew she couldn’t afford to wait for the ambulance to arrive.“The only thing I could think was to go out into the street.” She said.“I rushed out and screamed for someone to help while my grandma rushed out crying with Tallulah.”At exactly the moment, Caitlin, who is studying public services atRedcarCollege, was passing byQueen Street. She said, “I was waiting to go to work when I heard someone screaming for help, so I ran straight over.”The 17-year-old girl added, “Something just clicked and I went into auto mode. The little girl was completely limp, so I checked her airways and tilted (使倾斜) her over and started hitting her back. I turned her round andtapped on her chest, then after what felt like forever she coughed up the sweet and spat it out.As soon as she started crying I felt a huge relief. I was just so pleased I was able to help.”Caitlin was taught her lifesaving skills when she joined the Army Cadets four years ago.12. When did Tallulah get choked?A. While eating sweets.B. While enjoying a drama.C. While having a meal.D. While taking some medicine.13. Why did the family go out into the street?A. To buy some needed tools.B. To search for timely help.C.

2020年成都七中初中学校高三英语期中考试试题及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AIt looks like 2017 is shaping up to be a record-breaking year in movie History. Here is a list of some of the year’s biggest blockbusters so far.Kong: Skull IslandA reboot (重启) of King Kong would normally get laughed at in this day and age, but it looks like this modem version of the story will be worth watching. With US actress Brie Larson and UK actor Tom Hiddleston in the mix, this film is set to be this year’s biggest monster tale.Release Date:3/10/17Beauty and the BeastDirector Bill Condon is bringing back a part of our childhood in live action, complete with the songs we all remember and love. With British stars Emma Watson and Dan Stevens leading thecast, the classic Walt Disney story already sounds like it’ll be a delight for both children and adults.Release Date:3/17/17The Fate of the FuriousThere was doubt that we’d even get a Fast 8, especially after the fitting ending US actor Paul Walker’s character was given at the end of Furious 7.

Adults ages 60 and older who took afternoon naps showed signs of better mental ability compared to those who didn’t nap, according to a study published in General Psychiatry earlier this week.Researchers analyzed napping habits in 2, 214 older Chinese people and measured their cognitive abilities using several cognitive tests. Participants took the Mini-Mental State Examination and theBeijingversion of the Montreal Cognitive Assessment, both of which test for memory, language and other cognitive abilities. In every category listed in the study, nappers tested statistically higher on average compared to their non-napping counterparts.Researchers did not gather data from people under 60, so a correlation cannot be drawn between napping and younger generations. The study also noted that there are conflicting studies about the benefits and risks of napping.Sleeping behaviors can be affected by a multitude of factors, said Dr. David Neubauer, associate professor atJohnsHopkinsUniversity. “Daily routines, medication use and sleep disorders can all play a role in how frequently someone takes a nap.” he said.Neubauer recommended taking a shorter “power nap” of up to 20 minutes to decrease the chances of transitioning into slow-wave sleep, which makes people feel groggy when they wake up. “Napping can be a healthy part of an older adult’s day”, Neubauer acknowledged, but make sure “sleepiness isn’t due to a treatable nighttime sleep disorder.” Older individuals who want to do all they can to preserve their cognitive functioning should put nighttime sleep first.4. What is the best way to keep a better cognitive ability for the old?A. Take a nap every day.B. Take sleep disorder seriously.C. Have a good sleep at night.D. Do exercise regularly.5. How did the researchers reach the conclusion?A. By taking the examinations and assessment.B. By analyzing napping habits and giving tests.C. By measuring nappers’ ability and analyzing them.D. By doing an experiment.6. Which has NO effect on one’s sleeping behaviors?A. Taking a nap.B. Medicine treatmentC. Sleep problemsD. Everyday activities.7. What can we know about “slow-wave sleep”?A. It appears in short nap up to 20 minutes.B. People should avoid it in their naps.C. It is a healthy part of an elder’s day.D. It was recommended by Neubauer.CChancellor of the Exchequer George Osborne said yesterday he would use the autumn spending review to increase Britain’s￡12bn-a-year aid budget towards humanitarian(人道主义的) causes in the wake of the European refugee(难民) crisis.Britainpromised to spend 0.7 percent of state general product on aid, meaning the budget could rise sharply by the end of the decade as the economy grows.Mr Osborne also said more of the aid budget could be given to help local government with housing costs for incomers, without breaking international guidelines.“We will use the foreign aid budget to help with the costs of these refugees. People ask about the pressure on public services; we’ll have extra money to help with that.”The government was unable to give a figure for how much aid money could be handed to local authorities: it would depend on how many refugees are accepted.David Cameron, Prime Minister, will set out his position on aid for refugees today. It is reported thatBritainwill accept at least 10,000 extra people from camps on theSyriaborder. He will use a statement in the House of Commons to flesh out plans — announced inMadridon Friday — to take more people.A report inThe Sunday Timesthat the UK would take 15,000 Syrians, not far from the 18,000 figure demanded by the EU, was described by “Downing Street” as a “guess”.TheUKwill offer to resettle Syrians directly from refugee camps inJordan,LebanonandTurkey— but not those who have already reached the EU.8. What is the main idea of the passage?A. Britain tried to help refugees.B. People doubtBritain’s kindness.C. Britain tried to explain its behavior.D. Refugees like to live inBritain.9. What can we infer from the first two paragraphs?A. Britain’s economy grows rapidly.B. Britain will use little of its money to help refugees.C. Most countries are not willing to help refugees.D.Britainwill use more money to help refugees.10. Which of the following statements is TRUE?A. Britain will use foreign money to help refugees.B. Britain helps refugees following international guidelines.C. Britain will use foreign money to develop themselves.D. People ask to use public service money to help refugees.11. What can we know from the passage?A. Britain can hold 10,000 refugees at most.B. The number of refugees to be received is uncertain.C. House of Commons declare a general plan.D.Britaincan hold 15,000 refugees at most.DWhere do you find beauty? Fashion Magazines? Music Videos? One American photographer is finding beauty in unexpected places. And a new documentary about his work might help change the traditional standards of “who” is beautiful.Rick Guidotti put aside his career as a fashion photographer to turn his lens to people living with genetic, physical and behavioral differences. He says what changed his perception of beauty was a chance encounter with an albino （白化病）girl.“I was just tired of people telling me who was beautiful. Every season that face would change but I was always told who was beautiful. As an artist, I don't see beauty just on covers of magazines. I see it everywhere. So it was my initial intention that opened my eyes a little wider and wider.” Said Guidotti.Guidotti has created Positive Exposure, a not-for-profit organization that uses photography and video to transform public views and promote a world where differences are celebrated. Guidotti and Positive Exposure are featured in a new documentary called On Beauty.The cast and crew recently hosted a screening at Georgetown University in Washington. One of the women featured in the film is Jayne Waithera. “I never thought I was beautiful because nobody said that to me, but meeting him was my profound moment. I remember that particular day he took my picture and I felt so good like I felt there's somebody who, really loves me and sees me for who I am and who sees me more than my condition.” said Waithera.The documentary is the idea of producer Joanna Rudnick. After seeing Guidotti's photos, she decided to tell his story. Joanna and Guidotti are traveling from city to city to promote On Beauty. “As I travel from community to community, I'm taking photographs and I'm encouraging individuals with a positive sense of who they are. They're seeing beauty in their reflection but I'm also encouraging their families and they in turn are encouraging their communities as well. All is based on the philosophy of change how you see,see how you change.”12. What made Rick change his understanding of beauty?A. A girl diagnosed with albino.B. His job as a fashion photographer.C. The beauty on the covers of magazines.D. Influence from the people working with him.13. What can we infer about Jayne Waithera?A. She showed great interest in taking photos.B. She used to be disappointed at her work and life.C. She was greatly influenced by the experience with Rick.D. She believed Rick was the best photographer in the world.14. Which of the following words can best describe On Beauty?A. abstract and differentB. traditional and academicC. tolerant and encouragingD. creative and interesting15. What's the best title of the text?A. True Beauty In The Eye Of A PhotographerB. Beautiful Or Not Beautiful,That's A QuestionC. Be Who You Are Not Who You Want To BeD.

2020-2021学年成都市第七中学高三英语上学期期中考试试题及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ALast summer, Katie Steller pulled off the freeway on her way to work inMinneapolis. She stopped at a traffic light, where a man was sitting with a sign asking for help. She rolled down her window and shouted. “Hey. I’m driving around giving free haircuts. Do you want one right now?” The man laughed, then paused. “Actually,” he said, “I was really hoping to get a haircut.” Steller pulled out a red chair from her car and helped the man cut his hair immediately. After the work was done, the man looked in a mirror. “I look good!” he said.Up to now, Steller has given 30 or so such haircuts around the city to people with little influence, and she is strongly aware of the power of her cleanup job.As a teen, she suffered from a severe disease, causing her hair to get thinned, so her mother arranged for Steller’s first professional haircut. “To sit down and have somebody look at me and talk to me like a person and not just an illness, it helped me feel cared about and less alone,” she says. After that, Steller knew she wanted to have her own barbershop so she could help people feel the way she’d felt that day. Not long after finishing cosmetology (美容术) school in 2009, she began what she now calls her Red Chair Project, reaching out to people on the streets. Her aim was that by doing some kind acts, others would be inspired to spread their own.“Part of what broke my heart was just how lonely peoplelooked,” she said. “I thought maybe I’d go around and ask if people want free haircuts. I can’t fix their problems, but maybe I can help them feel less alone for a moment.”It all began with a belief in simple acts of kindness, such as a free haircut. “The way you show up in the world matters,” said Steller. “You have no idea what people are going to do with the kindness that you give them.”1. How does the writer begin the passage?A. By making a comparison.B. By giving a reason.C. By raising a question.D. By describing a scene.2. What made Stellar start the Red Chair Project?A. Her mother’s love for her.B. Her interest in cosmetology.C. Her care for those in need.D. Her wish to fight severe diseases.3. What did Stellar expect from the project?A. To spread kindness.B. To solve social problems.C. To deal with relationships.D. To make people look smarter.BNow most of the workers work from 9 am to 5 pm. However, according to the global Internet survey done by the UK Sleep Council, thesiesta（午睡）was the right idea all along. The UK Sleep Council called on the country'sbosses to end nine-to-five working in favor of more flexible hours. They believe what would really increase the workers' productivity is a nice afternoon nap, rather than those bonuses.Forty-one percent of the 12,000 people who responded to the council's survey said they were most productive in the morning, while 38 percent said theyhit their stridein the evening. "This means most of them cannot fully pay attention to what they do in the middle of the day," said sleep expert Dr. Chris Idzikowskii. "We must conclude from this survey that the traditional nine-to-five working day does not suit most workers." He suggested that allowing workers to follow their natural sleeping habits would actually benefit employers by allowing them to expand their working hours and be more productive.Fortunately, being a college lecturer, I don't have to go to work everyday. I only work three days a week, but during the three days I work really long hours and have no time for a little siesta. I'm usually so tired and sleepy in the afternoon, which really affects thevitality（活力）of my classes.I think Dr. Chris Idzikowskii's idea is worthwhile. When people have flexible working hours they could reach their highest productivity. On top of that, flexible working hours mean thatpeople don't have to work all at the same time. That way we could avoid traffic jams. Therefore, it's really killing two birds with one stone!4. What can improve the workers' productivity, according to the UK Sleep Council?A. More bonuses.B. The flexible working time.C. Working for long hours.D. Working in a relaxing way.5. What does the underlined part probably mean in Paragraph 2?A. Were most sleepy.B. Were most flexible.C. Worked at their own pace.D. Worked at their best.6. What did the UK Sleep Council's survey find?A. Few people are suitable to work at noon.B. People are more productive in the morning.C. Some people like to expand their working hours.D. More and more people prefer to work in the evening.7. Why does the author support Dr. Chris Idzikowskii's idea?A. It could solve most of the traffic problems.B. He finds Dr. Chris Idzikowskii respectable.C. He thinks the idea can benefit the society.D. It allows him to work for fewer hours.CThis past year, I've found myself returning again and again to lines of poetry by Emily Dickinson. Like many people, I've needed the curing effects of reading more than ever. As scientists and psychologists will tell you, books are good for the brain and their benefits are particularly vital now.Books expand our world, providing an escape and offering novelty, surprise and excitement. They broaden our view and help us connect with others. Books can also distract us and help reduce ourmental chatter.When we hit the “flow state" of reading where we're fully lost in a book, our brain's mode network calms down. It's a network of brain that is active and gets absorbed in thinking and worrying endlessly when we are not doing anything else.There is so much noise in the world right now and the very act of reading is kind of meditation. You disconnect from the chaos around you.You reconnect with yourself when you are reading. And there's no more noise.In 2020, the NPD Group recorded the best year of book sales since 2004. Yet even as people are buying more books,many are reporting they're having a harder time getting through them. It's difficult for your brain to focus on a book when it's constantly scanning for threats to keep you alive.Our fight-or-flight response has been consistently activated.Sometimes I picture my brain as a cartoon brain with little arms and legs, fighting with a book I am holding and screaming: “Can't you see I'm busy!” Anxiety causes our brain to produce a flood of stress,which consumes our energy and makes it harder to concentrate.Then one day in December sitting on my couch, I remembered how much I like to read"The House of Mirth" every few years around the holidays. The memory inspired me to pick up the familiar book, opened it up and started reading.I just kept going.The comfort and distraction and brain-opening experience gave me peace.So return to something familiar.8. What does the underlined part “mental chatter” in Paragraph 2 mean?A. Getting lost in a book.B. Non-stop inner anxiety.C. Chatting with the author.D. Powerful network of brain.9. What do we know about reading according to the text?A. It can treat our headache.B. It can calm down the noisy people.C. It forces us to concentrate.on thinking.D. It makes us communicate with ourselves.10. Why was it difficult for people to finish reading books in 2020?A. People bought too many books.B. The books were too difficult to understand.C. People just wanted to escape from the threat.D. The life threat disturbed people's focus on books.11. Why is the author's experience mentioned in the last paragraph?A. To rid people of concern for safety.B. To present an effective reading way.C. To wake up memories of an old book.D. To recommend the book he/she reads.DIf you travel inAthens, against popular belief, I would highly recommend saving the Acropolis for your secondday. As attractive as it is to head straight to the most famous building in the city, there are several reasons why you should hold off until later.Sunriseis the best time to see the ruins, and who wants to spend their first day in anew citywaking up at6 a.m.? On top of that, the Acropolis is going to make every other site inAthensless important in comparison, so I recommend not hitting it on your first day.We got to the southeast gate at 7：30, half an hour before it opened at 8. When the gate opened, we rushed to the hill. Our plan paid off because we had the whole complex to ourselves for five minutes. In this age of overtourism, getting to the greatness of the Acropolis with nobody else around felt special and excited.The Acropolis is the name given to the complex on top of the hill, and it’s made up of several buildings. There’s theTempleofAthena Nike, the Parthenon, the Old Temple of Athena, the Legendary Olive Tree of thePandroseion, the Porch of the Caryatids at the Erechtheion... and on your way down, the Odeon of Herodes Atticus.Something that sounds boring but isn’t is theAcropolisMuseum, and I recommend spending a couple of hours there. As someone who is a museum-avoider, I listened to the recommendations of everyone who had been, and made myself go inside. And I loved it. The museum houses tons of sculptures unearthed from the Acropolis, and it was interesting to check them out.Head toSyntagma Squarenext to watch the changing of the guard. This takes place every hour on the hour, so try to time your visit perfectly. The guards wear fun clothes and make for interesting photos.12. The author suggests visiting the Acropolis on the second day so that ___________.A. it can save visitors a lot of timeB. it can save visitors from getting up earlyC. it can make for a better travel experienceD. it can give visitors a better understanding ofAthens13. How did the author feel when he ran to the top of the hill?A. Bored.B. Worried.C. Relaxed.D. Amazed.14. With what may the author agree about theAcropolisMuseum?A. It is so great that it should be visited last.B. It is enjoyable and worth visiting.C. It wastes a lot of time.D. It should be avoided.15. What is the purpose of the text?A. To provide some advice on visiting the Acropolis.B. To introduce the history of the Acropolis.C. To call on people to protect historic sites.D. To encourage people to travel around.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。

Scientists fear the iceberg could crash into the island and block major feeding areas for a large population of penguins and seals. If the iceberg hits the island, it could prevent the penguins and seals from reaching food supplies.The huge iceberg is named A68a. It broke away fromAntarctica's Larsen C Ice Shelf in 2017. Satellite images show the iceberg has remained in one piece. It is estimated to be about 150 kilometers long and 48 kilometers wide. It is traveling at one kilometer per hour and is on a path to hitSouth Georgiain around 30 days.This is the time of year when seals and penguins spend a lot of time caring for their young. The distance that parents have to travel to find food is crucial. That means they have to go a lot further or go around the iceberg to find sources of food.Ecologists say an iceberg crash would also disturb materials settled on the seabed, possibly polluting the surrounding seas. As the iceberg melts, it would also release large amounts of fresh water into the ocean. This could affect krill（磷虾）populations that are a major source of food for the island's wildlife. The iceberg could remain for up to 10 years and change the area's whole ecosystem. These are globally significant populations of these species. If these species fail in this particular area, then the numbers globally are going to go down quite dramatically.Professor Geraint Tarling, an ecologist at the British Antarctic Survey, said, "The breaking off of icebergs fromAntarcticais a natural process. But the process is changing with climate change. What we're seeing with models and some observations now is that this is happening at an increasing rate. And so, this might become more of a usual thing in the future."4. Why are the scientists worried about the coming iceberg crash?A. It will bring extremely cold weather.B. It will destroy the feeding areas of the animals.C. It will put wildlife on the island at risk of starving.D. It will prevent animals from moving to other places.5. What is paragraph 2 mainly about?A. The characteristic of the iceberg.B. The importance of the iceberg.C. The traveling speed of the iceberg.D. The forming process of the iceberg.6. What damage can an iceberg crash bring according to paragraph 4?A. Using up much fresh water.B. Polluting the surrounding farms.C. Changing the world's ecosystem.D. Affecting the number of certain species.7. How does Tarling think of the breaking off of icebergs fromAntarctica?A. It may slow down in the near future.B. It may become common in the future.C. It has a great influence on the climate.D. It helps scientists conduct a sea study.C"Sorry, but I don't agree with you..."This is usually followed by unbearable silence and angry tears. I've always found it difficult to disagree with someone, because I don't want to lose a friend. I've found it even harder to accept it when someone disagrees with me, because my ego（自尊心）ishurt.Before the other person gets a chance to explain why she disagrees with me, my usual response would be," If you aren't able to see my point of view, then what you think isn't worth my time or consideration, either." But now I've come to realize that when a friend disagrees with me, sometimes she is simply saying, "I don't agree with the way things are done." She still respects me as a person, and is only pointing out a better way to look at a matter. However, there may be times when my friend disagrees with me because I'm against the truth. That's when need to listen to what she says.I've learned that one way to help my friend is for me to be open and honest with the other to voice my thoughts and listen to the other carefully. While we can't control how a person will respond to our views, we must learn to disagree with our friends in love. We will never feel that we are better than the other person.And that will help us to be less emotional, and more objective in the way we express our opinions.In the same way, we can also stay open to feedback（反馈）from others,knowing that our friends may be correcting us in love.Good friendships build each other up, sometimes through disagreements and honest opinions. Though Idon't like being disagreed with, I'm starting to see the value of such disagreements.8. The author has found it difficult to disagree with someone because .A. he is a friendly personB. he usually hides his ideasC. he has no mind of his ownD. he wants to keep the friendship9. When a friend disagreed with him,the author used to .A. be unhappyB. argue with the friendC. break up with the friendD. explain things calmly10. The author will listen to a friend when .A. he is against the truthB. he doesn't tell the truthC. he is respected by a friendD. he does things in the wrong way11. What does the author mainly talk about in the text?A. How to keep friendship.B. How to avoid hurting a friend.C. How to express disagreements.D. How to deal with disagreements.DIf you believe in thermometers (温度计), you should believe in global warming. And if you believe in eating French fries with your hamburger, you should worry more about carbonemission.It won't happen overnight, but as the planet’s climate changes, the growth cycles of main crops will all be heavily affected. Here are three of the crops that might not beat the heat.The potato actually needs a great deal of beauty rest to develop properly. “They need a cool nighttime temperature in order to start growing the tuber, the part that we eat,” Nelson says.Temperature and altitude are two primary concerns in coffee growth, and farmers are stuck between a rock and a hard place. “We know that coffee grows in a certain temperature range,” Nelson says. “They've been moving up the mountains, but at some point you run out of mountains to move up.” Higher-grade strains of Arabica coffee in Central American regions are at particular risk due to the need for lower growing temperature, especially since diseases and pests are also becoming more of a factor as temperatures rise.Even if you're looking at the direct effects of temperature alone, rice is in trouble. “As nighttime temperatures go up, the rice is going to have a problem flowering and won't make as many seeds,” Nelson says. In addition to this direct heat consequence, rising sea levels will flood many rice paddies and destroy water salinity levels, while droughts will lower production, raise prices, and further shame westerners who are clumsy with chopsticks to be able to clear their plates once a new grain is adopted.12. What is the closest meaning to the underlined word “emission” in Paragraph 1?A. Mixture.B. Pollution.C. Giving off.D. Going down.13. What does the potatoes' development need according to Nelson?A. Cool temperature at night.B. Sudden rise of the temperature.C. Enough water and salt.D. Much sunshine and fresh air.14. The rice is difficult to flower,probably because ________.A. sea levels go up suddenlyB. many seeds can't be producedC. the temperature rises at nightD. both temperature and altitude rise15. What is the best title for the text?A. How Does Global Warming Affect WesternersB. How Does the Cool Temperature Affect RiceC. What Is the Real Reason For Crops’ GrowthD. Three Crops That Won't Survive Climate Changes第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2020年成都市第七中学高三英语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AOur Teen Summer Spanish Program is two weeks of fun, educational excitement that helps students learn Spanish fast. Our Spanish summer program allows our students to learn from highly trained, certified teachers and be absorbed in the language and theculture of Costa Rica.Features include:* Intensive(强化的) daily Spanish classes* Extracurricular classes in dance, cooking, music, and handiwork* Outdoor activities including hiking, camping, rafting, and ziplining(高空滑索)* Homestay with a local Costa Rican family* Volunteer work in needy neighborhoodsOur Teaching Methods:We are proud to use TPRS---Total Physical Response Storytelling---in our curriculum. This innovative method uses strange and amusing stories to teach new vocabulary, increase fluency, and get students involved by giving them the opportunity to alter the details themselves. Because of the silliness, creativity, and repetition involved, TPRS allows students to learn easily and remember information effortlesslyMemorizing vocabulary and listening to lectures on grammar are slow, inefficient ways to learn a new language. The best way to truly learn and commit new material to memory is through conversation. In our Spanish classes, students can expect to speak up to 80% of each class. By speaking in the new language freely and consistently, students can see progress faster because they are using the new grammar and vocabulary that they have learned at the same time. This helps the brain remember the new words and grammar structures for future use, making it much easier to progress.1.What does the program do?A.It offers weekly Spanish classesB.It focuses more on outdoor activitiesC.It gives teachers a chance to receive trainingD.It provides activities about the Spanish culture2.What is the best way to learn a language according to the text?A.Memorizing a larger vocabularyB.Speaking more in the new language.C.Mastering more grammar structuresD.Writing stories to share with others3.What is the purpose of the text?A.To employexperienced Spanish teacherB.To hire foreign volunteers for a programC.To attract teen foreigners to a programD.To introduce language learning methodsBThe Great Barrier Reef's outlook remains “very poor” despite coral (珊瑚) recovery over the past year, Australian government scientistssaid Monday, just days before a UNESCO ruling on the site's world heritage (遗产) status.The United Nations cultural agency recommended last month that the world's largest reef (珊瑚礁) system be placed on its endangered list because of damage to the corals largely caused by climate change.The Australian Institute of Marine Science (AIMS) said the corals were now in a “recovery window” after a decade of harmful heat stress and cyclones (旋风). But such opportunities were becoming rarer due to the influence ofclimate change, the government agency, which has monitored the reef for 35 years, said in its annual report released today. “The increasing emergence of climate-related extreme weather events and starfish outbreaks is causing more severe and frequent pressures, giving the reef fewer opportunities like this to recover,”CEO Paul Hardisty said. The scientists surveyed 127 reef sites in 2021 and found hard coral cover had increased at 69 of the 81 locations surveyed in the past two years.Separate scientific research released last October found the 2, 300-kilometre (1, 400 miles) system had lost half its corals since 1995, with a series of ocean heatwaves causing mass coral death.Britta Schaffelke, research program director at AIMS, said the latest findings provided a slight hope that the reef still has the power of recovering. But she added that its future is still very poor because of the dangers of climate change and other factors that are affecting the reef.UNESCO has urged Australia to take urgent climate action but the government has long resisted calls to commit to net zero emissions (排放) by 2050. The government has said it hopes to meet the target “as soon aspossible” without harming its economy, insisting dealing with climate change requires a global effort. The reef was worth about US $4. 8 billion a year in tourism for the Australian economy and there are fears that an “in danger” listing could weaken its tourist appeal.4. What is the major cause of the damage to the corals?A. The climate change.B. Lack of money.C. Over development.D. Too many tourists.5. What is mainly talked about in Paragraph 3?A. The result of the survey.B. The efforts AIMS has made.C. The slight chance of the recovery.D. The terrible situation of the climate.6.

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 holdingback 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.

Try to avoid admitting our feelings.DWhen I was a child, I attained high grades in my academic study. However, I was physically uncoordinated because I was running too slowly. But for future college application, sport was a must. So I took up fencing (击剑) because I thought it required more strategy than athletic ability.Then I joined the school’s fencing team. My movements were clumsy compared to the seniors. One afternoon after a whole lesson’s failure, tears of frustration welled up in my eyes. One of my teammates approached me, “Could you tell me where your blade (剑) hit me?” She asked. I pointed to her right shoulder. Shenodded and patted my stomach, “That’s where I hit you.” She had begun to walk away when I blurted out, “Want to practice together? Again?”We practiced until we both felt more confident. But it wasn’t just the two of us. All these girls were entirely willing to share their knowledge with everyone, helping each other to grow.That afternoon, I watched a senior fencer execute a flawless attack admiringly. Something inside me suddenly bloomed. I realized later that it was love for both fencing and the fencing team.During the city championship, I was selected to fence. My opponent was the best fencer on her school’s team. “Ready, fence.” The match began. Suddenly, my opponent’s blade hit me. The score was 1-0.At the moment I could hear my teammates shouting, “Keep distance!” And the team captain’s voice was clear and commanding, “Parry, then disengage!”Fencing, unlike academics, wasn’t something I could succeed in by myself—even during an individual match, my teammates were still giving me advice. Unathletic as I was, I was proud to be an athlete and a teammate.I saw my blade tip bury itself into my opponent’s shoulder and the judge signaling that it was my point. I could taste the sweat on my lips, which were breaking out into a smile.12. Why did the author start to learn fencing?A. Because she needed to train her coordination.B.

What distinguishes fencing from academics according to the author?A. Strong determination.B. Hard work.C. Athletic strategy.D. Team support.15. How did the author feel when she got her point?A. Unbeatable and respectful.B. Sweaty and ashamed.C. Energetic and secure.D. Proud and thankful.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。

Dear Jim,
I’m glad to hear that you are interested in Chinese novels and I’m writing to recommend one to you.
Journey to the West is an outstanding romantic novel full of fantastic tales. The novel tells the story of a monk overcoming 81 adversities assisted by his three disciples. Recognized as one of the best Chinese classical novels, Journey to the West not only describes various characters vividly, but also conveys the message that intelligence, determination and bravery are the keys to success.
To better understand the novel, it is suggested that you watch the TV series adapted from the masterpiece first. A simplified version of the novel might also be helpful.
I hope you will enjoy your reading!
Yours,
Li Hua。
