2020年肥乡县第一中学高三英语第一次联考试题及答案解析
2020年肥乡县第一中学高三英语第一次联考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.BThere are 8.8 million blind people in India. In fact, there are 36 million blind people worldwide and a quarter of them are in India; however, many cases of blindness in India are curable. The poor in India have limited access to primary eye healthcare and often do not eat foods rich in micronutrients, like vitamins and minerals, which play an important role in maintaining good eye health.Many people worldwide are not even aware that they may have a vision (视力) problem simply because they do not get their eyes tested every year with a doctor, who tests for the functioning of the eye muscles (肌肉), as well as common diseases like night blindness. This exam is strongly recommended by experts because some changes in vision, which the patient may take longer to notice, can be found easily in this way.Certain simple changes in diet and lifestyle can ensure better eye health for you. These include drinking plenty-of water, not smoking, and eating brightly color1 ed and leafy fruit and vegetables. Wearing sunglasses protects your eyes from the sun, which damages otherwise healthy eyes. Learn about your family's eye disease history, and be on the lookout for any problem about your vision. Make sure that you see a doctor immediately for early intervention(干预) if you see any of these signs of worsening eye health.If you or a loved one needs to cure blindness or other eye diseases, turn to a crowdfunding (众筹) platform. A group of eye health caregivers have fundraised with crowdfunding platform ImpactGuru to raise money to perform operations on the eyes of blind women in south Asia. Running an online fundraiser enables both doctors and patients to find a way out of the dark. If you want eye care to develop, start a fundraiser today.4. Why are there so many blind people in India?A. There is a lack of eye hospitals in India.B. People pay no attention to their eyes at all.C. Poor Indians lack food good for eye health.D. The environment damages their eyes.5. What does the author suggest in Paragraph 2?A. Examining your eyes annually.B. Strengthening muscles every day.C. Raising the awareness of physical health.D. Attaching importance to self-examination.6. Which of the following may do harm to your eyes?A. Smoking a lot.B. Wearing sunglasses.C. Drinking much water.D. Watching brightly-color1 ed pictures.7. What does the author want to show in the last paragraph?A. How to start a fundraiser online.B. The importance of raising money.C. The role of crowdfunding in eye care.D. What should bedone to raise money.CHave you ever thrown a camel? Camels are large and heavy animals so it would be hard to throw. But in the French-speaking Democratic Republic ofthe Congo, “to throw a camel” is a way of saying “to make a spelling mistake”.In the past, a phrase like that was not accepted by the French government as an official French term. But recently, the French Ministry of Culture worked on a new kind of dictionary that accepts the idea that many people outside of France speak the language. The language has changed over time and is different in places like Ivory Coast in West Africa or Quebec in Cana-da, compared to how it is in ParisA new online dictionary, called the French speakers’ dictionary, includes new French words from around the world. It was released on March 18—just in time for International French Speaker’s Day on March 20.Supporters say the new Internet dictionary is more democratic than earlier French dictionaries that only showed the way highly educated French people spoke. The new dictionary includes unofficial words like “pourriel”, which means an unwanted email if you are in Canada. It is a word based on “courriel”, which just means an email.French President Emmanuel Macron proposed the idea of the dictionary in 2018. It now contains about 600.000 terms, Roselyne Bachelot is the French Culture Minister. She said the dictionary is not just for France's 67 million citizens, but for the 300 million French speakers worldwide.The aim, supporters say, is to recognize the way language changes. Words and expressions included in thedictionary come from over 50 countries—even from the United States Some people in the southern U. S. state of Louisiana speak French.People can see the dictionary on a website or with an app. Users can also send in new words they think should be included. Official dictionaries produced by the French Academy in Paris were first published hundreds of years ago and are regularly updated.8. What do we mean if we say a man “throws a camel” in French?A. He talks big.B. He is very strong.C. He makes a joke.D. He misspells a word.9. What is the purpose of the publication date of the new online dictionary?A. To celebrate an event.B. To honor foreign users.C. To draw more attention.D. To meet an urgent need.10. Where does the word “pourriel” come from?A. French.B. An email.C. A holiday.D. Canada.11. What can people do with the new dictionary?A. Update it regularly.B. Recommend new words to it.C. Change the meaning of its words.D. Regard it as an official dictionary.DHoneybees can’t swim, and when their wings are wet, they can’t fly, either. But Chris Roh and other researchers at the California Institute of Technology found that when bees drop into bodies of water, they can use their wings toproduce little waves and slide toward land-like surfers who create and then ride their own waves.As with many scientific advances-IsaacNewton’s apple or Benjamin Franklin’s lightning bolt-Dr. Roh’s experiment began with a walk. Passing Caltech’s Millikan Pond in 2016, he observed a bee on the water’s surface producing waves. He wondered how an insect known for flight could push itself through water.Dr. Roh and his co-worker, Morteza Gharib, used butterfly nets to collect localPasadenahoneybees and observed their surf-like movements. The researchers used a wire to restrict each bee’s bodily movement, allowing close examination of their wings. They found that the bee bends its wings at a 30-degree angle, pulling up water and producing a forward force. Bees get trapped on the surface because water is roughly three times heavier than air. But that weight helps to push the bee forward when its wings move quickly up and down. It’s a tough exercise for the bees, which the researchers guess could handle about 10 minutes of the activity.The researchers said the surf-like movement hasn’t been documented in other insects and most semiaquaticinsects use their legs forpropulsion, which is known as water-walking. It may have evolved in bees, they-predicted.Dr. Roh and Dr. Gharib have imagined many practical applications for bees’ surfing. One plan is to use their observations to design robots able to travel across sky and sea. “This could be useful for search and rescues, or for getting samples of the surface of the ocean, if you can’t send a boat or helicopter,” Dr. Gharib said.12. What does the author intend to show by mentioningNewtonandFranklin?A. Roh’s admiration for them.B. Roh’s chance discovery about bees.C. Their outstanding talent for science.D. Their similar achievements in discovery.13. What plays the most vital role in a bee’s moving forward on water?A. The air weight.B. Its leg extension.C. The water movement.D. Its continuous wingbeat.14. What does the underlined word “propulsion” in Paragraph 4 mean?A. Fast flightB. Driving force.C. Pulling speed.D. Explosive power.15. What does the text mainly tell us?A. Honeybees can surf to safety.B. Bees help scientists make inventions.C. Insects can adapt to the environment.D. Nature is a helpful guide for discovery.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届肥乡县第一中学高三英语一模试题及参考答案
2020届肥乡县第一中学高三英语一模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AThe history ofpop art begins with abstract art. Pop art emerged from the foundation of abstract art in the 1950s, first gaining recognition in Great Britain, then establishing itself in the United States in the 1960s.In the 1930s and 1940s, abstract art was greatly popular, but people began to hate this art form. Most abstract art produced in this era could be found in art galleries or the homes of the elite(名流), not in the homes of everyday people. Pop art sprung onto the scene as the people's art.Some art critics say pop art is a rebellion against abstract art; others say it is an extension of abstract art. You can see elements of abstract art in many pop art prints, especially those that consist of a collage（拼贴画）of images. However, some pop art pieces have nothing to do with abstract art, looking more like a photo of a popular consumer item, which impressed people deeply.Richard Hamilton and Eduardo Paolozzi were two of the first contemporary pop art pioneers recognised in Great Britain. They were a part of the Independent Group, an organised group of British artists who wanted to challenge ruling modernist approaches to culture. They recognised the value of modern advertising and comic book images. They used these popular images in art as a social commentary, often building irony and humour into their artworks, thus creating a new form of art. These pieces were mass-produced and sold at affordable prices.When pop art took off in the United States, it expanded to include a celebration of kitsch and the common images found in movies and television. Andy Wharhol is perhaps the most famous American pop art artist, known for his prints of the actress Marilyn Monroe, the singer Elvis Presley and of Campbell's soup cans. Andy Wharhol was inspired by images from advertisements and common consumer items. He also made a series of paintings which showed images of car accidents.1. Why did people dislike abstract art?A. People found it hard to understand.B. Ordinary people couldn't afford it.C. People disliked enjoying it in galleries.D. It wasn't based on everyday life.2. What impression do pop art works leave on people?A. They are a rebellion against abstract art.B. They have many elements of abstract art.C. They are created so real.D. They are products of advertisers.3. The Independent Group was set up to ________.A. introduce a new art form to the worldB. develop modern advertising furtherC. create new comic book imagesD. make British culture better knownBBrown cows may not actually make chocolate milk, but pink silkworms（蚕）do produce pink silk, a team of scientists has discovered. To see if they could produce pre-dyed silk-silk that comes color1 ed, straight from the source-the team fed ordinary silkworms mulberry（桑树）leaves that had been sprayed（喷洒）with fabric（织物）dyes（染色剂）. Out of seven tested dyes, only one worked, producing a thread that reminded me of pink-dyed hair.And yes, the worms themselves take on some color1 before they produce silk. Their color1 ful diets did not affect their growth, the team, which included engineers and biologists from the CSIR-National Chemical Laboratory in India, reports in the journalACS Sustainable Chemistry & Engineering. (The researchers didn't look too deeply into how the dyes affected the silkworms' health. After all, silkworms die when people harvest their silk.)The team made dyeing silk this way because color1 ing fabric normally uses large amounts of fresh water. The water gets polluted with dangerous chemicals in the process, requiring costly treatment before factories can send it back into waterways. Dyeing silk directly by feeding silkworms would avoid those water-washing steps. Scientists are just starting to study this idea. However, it remains to be seen if it's commercially successful. In this experiment, the Indian team tested seven dyes, which are cheap and popular in the industry.The scientists found different dyes moved through silkworms' bodies differently. Some never made it into the worms' silk at all. Others color1 ed the worms and their silk but the color1 disappears before the silk is turned into fabric. Only one dye, named "direct acid fast red", showed up in the final, washed silk threads. By the time it made it there, it was a pleasant, light pink.4. The text is most probably a(n) ________.A. science reportB. tourist guideC. animal experimentD. fashion advertisement5. Silkworms can produce pink silk because ________.A. they are born pinkB. they are dyed pinkC. they grow in pink waterD. they are fed dyed food6. Where is the experiment carried out?A. In America.B. In India.C. In Israel.D. In China.7. How many dyes have been proved successful in the experiment?A. One.B. Three.C. Five.D. Seven.CToo much TV-watching can harm children’s ability to learn andeven reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children.One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedroom TVs.A second study ,looking at nearly 1000 grown-ups in New Zealand, found lower education levels among 26-year-olds who had watched lots of TV during childhood.But the results don’t prove that TV is the cause and don't ride out that already poorly motivated youngsters (年轻人）may watch lots of TV.Their study measured the TV habits of 26-year-olds between ages5 and 15. These with college degrees had watch an averageof less than two hours of TV per week night during childhood, compared with an average of more than 2.5 hours for those who had no education beyond high school.In the California study, children with TVs in their rooms but no computer at home scored the lowest while those with no bedroom TV but who had home computers scored the highest.While this study does not prove that bedroom TV sets caused the lower scores, it adds to increasing findings that children shouldn't have TVs in their bedrooms.8. According to the California study, the low-scoring group might _________.A. have had computers in their bedroomsB. not be interested in mathC. be unable to go to collegeD. have watched a lot of TV9. What is the researchers' understanding of the New Zealand study results?A. Poorly motivated 26-year-olds watch more TV.B. Habits of TV watching reduce learning interest.C. The connection between TV and education levels is difficult to explain.D. TV watching leads to lower education levels of the 15-year-olds.10. What can we learn from the last two paragraphs?A. TV sets shouldn't be allowed in children's bedrooms.B. Children should be forbidden from watching TV.C. More time should be spent on computers.D. Further studies on high-achieving students should be done11. What would be the best title for this text?A. Computers or TelevisionB. Effects of Television on ChildrenC. Studies on TV and College EducationD. Television and Children's Learning HabitsDBritish sculptor Jason Taylor has made it his mission to use his talent to conserve our ecosystems by creating underwater museums. Over the years, the environmentalist has put over 850 massive artworks underwater worldwide. On February 1, 2021, Taylor launched his latest work — The Underwater Museum of Cannes.―The main goal was to bring attention to the fact that our oceans need our help,‖ Taylor told Dezeen. ―Ocean ecology has been destroyed by human activity in the Mediterranean over the past few decades, and it is not obvious what is taking place when observing the sea from afar.‖The Underwater Museum of Cannes contains 6 sculptures featuring local residents of various ages. They range from Maurice, an 80-year-old fisherman, to Anouk, a 9-year-old student. Towering over 6-feet-tall and weighing 10 tons, the faces are sectioned into two parts, with the outer part like a mask. The mask indicates that the world’s oceans appear powerful and unbeatable from the surface but house an ecosystem that is extremely fragile to careless human activities.Though the waters surrounding the sculptures now appear a pristine blue, the seabed was filled with old boat engines, pipes, and other human-made trash when the project began about four years ago. Besides removing the trash, Taylor also restored the area’s sea grass. Just one square meter of the sea grass can generate up to 10 liters of oxygen daily. The sea grass also helps prevent coastal erosion and provides habitats for many ocean creatures.―The idea of creating an underwater museum was to draw more people underwater and develop a sense of care and protection,‖ Taylor told Dezeen. ―If we threw unwanted waste near a forest, there would be a public outcry. But this is happening every day in our surrounding waters and it largely goes unnoticed.12. Why does the outer part ofthe sculptures look like a mask?A. To popularize the features of the locals.B. To remind people to protect themselves.C. To reflect people’s protection of the ocean.D. To stress the sensitiveness of the ecosystem.13. What’s paragraph 4 mainly about?A. How the project was started.B. How the sea grass was restored.C. What recovery effort the project made.D. Why the surroundings were improved.14. What can we infer from what Jason Taylor said in the last paragraph?A. The situation of the ocean is easily ignored.B. The destruction caused to the ocean is noticeable.C. Forests play a more important role in ecosystems.D. People have zero tolerance to damage done to nature.15. What might be the best title for the text?A. The Underwater Museum, a long way to go.B. The Underwater Museum, a big difference to the sea.C. The Underwater Museum, an appeal to conserve ecosystems.D. The Underwater Museum, a masterpiece of Jason Taylor.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2020年肥乡县第一中学高三英语一模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AOn a rainy afternoon, maybe one of the following books will keep you company leisurely, allowing you to spend your time alone as well as stepping into a different world.Don’t Shed Your Tears for Anyone Who Lives on These Streets,by Patricio PronIn April 1945,Italy, a writer disappeared at a conference and was found dead at another place. Thirty years later, a young man interviewed survivors from the conference, trying to uncover the truth about what happened and its consequences. This novel, by a well-known Argentine writer, explores art, crime and politics.When Breath Becomes Air, by Paul KalanithiAt thirty-six, Paul Kalanithi was diagnosed (诊断) with stage IV lung cancer. One day he was a doctor treating the dying, and the next he was a patient. This autobiography finds hope and beauty in the face of death as Kalanithi attempts to answer the question “What makes a life worth living?”.To Killa Mockingbird, by Harper LeeSet in a smallAlabamatown in the 1930s, the story focuses on honest, highly respected lawyer Atticus Finch who puts his career on the line when he agrees to represent Tom Robinson, a black man accused of committing a crime.Nobody Will Tell You This But Me: A true (as told to me) storyby Bess KalbBess Kalb saved every voicemail from her grandmother Bobby Bell who died at ninety. In this book, Bobby is speaking to Bess once more, in a voice as loving as it ever was in life and brings us several generations of brave women. They include Bobby’s mother, who traveled alone fromBelarustoAmericato survive, and Bess’s mother, who always fought against convention.1.What type of book is the first novel?A.Sci-fi.B.Biography.C.Detective books.D.History books.2.Which book explores life and death?A.To Kill a MockingbirdB.When Breath Becomes AirC.Don’t Shed Your Tears for Anyone Who Lives on These StreetsD.Nobody Will Tell You This But Me: A true (as told to me) story3.Who is the main character in the last novel?A.Bobby Bell.B.Bess Kalb.C.Bess’s mother.D.Bobby’s mother.BNASA has flown an aircraft on another planet for the first time. On Monday, April 19, Ingenuity, a 1. 8-kilogram drone (无人机) helicopter, took off from the surface of Mars, flew up about threemeters, then hovered for 40 seconds and took photos above with one of its two cameras. The historic moment was livestreamed on YouTube. “We can now say that human beings have flown a drone helicopter on another planet,” said MiMi Aung, the Ingenuity Mars Helicopter project manager at NASA's Jet Propulsion Laboratory, at a press conference. “We, together, flew at Mars, and we, together, now have our Wright brothers moment,” she added, referring to the first powered airplane flight on Earth in 1903.The details: The flight was a significant technical challenge, thanks to Mars' s bone-chilling temperatures (nights can drop down to -130 °F / -90 °C) and its incredibly thin atmosphere — just 1% the density of Earth' s. That meant Ingenuity had to be light, with rotor blades (螺旋桨) that were bigger and faster than would be needed to achieve liftoff on Earth (although the gravity on Mars, which is only about one-third of Earth's, worked in its favor). The flight had originally been scheduled to take place on April 11 but was delayed by software issues.Why it's significant: Beyond being a significantmilestonefor Mars exploration, the flight will also pave the way for engineers to think about new ways to explore other planets. Future drone helicopters could help astronauts by scoping out locations, exploring inaccessible areas, and capturing images. Ingenuity will also help inform the design of Dragonfly, a car-size drone that NASA is planning to send to Saturn's moon Titan in 2027.What's next: In the next few weeks, Ingenuity will conduct four more flights, each lasting up to 90 seconds. Each one is designed to further push the limits of Ingenuity's capabilities. Ingenuity is only designed to last for 30 Martian days, and is expected to stop functioning aroundMay 4.

Ingenuity: Mars Drone Flies to Take Incredible PicturesCA company called Neuralink has shared a video which appears to show a monkey playing a video game, but what makes the video even stranger is that themonkey is playing the video game with just its mind.Neuralink is a company owned by Elon Musk, which is working to develop devices that could allow people to control things using just their brains. The monkey in the video is called Pager, having special "Link" devices inside his brain. These devices are connected to 2,048 wires which lead to the parts of Pager's brain that control movements of the arms and hands.Scientists taught Pager to play a video game using a banana juice as a reward when he playedthe game correctly. Soon Pager was eager to play well in order to get more smoothie. At first, Pager controlled the video game using a joystick (操纵杆). But as Pager played, his Link devices wirelessly sent out information about the signals his brain was using to control his arms and hands. Neuralink's scientists recorded all of these signals.Then they used computers to match up the signals from Pager's brain to the movements that his hands were actually doing. This was challenging work and the scientists counted on artificial intelligence (AI) to help them decode (解码) Pager's brain signals.The next step was to have a computer make moves in the video game as if Pager had actually moved the joystick. If Pager thought about moving the joystick up, the computer would send an "up"signal to the video game.Thus Pager was able to play the video game using just his brain.When people are paralyzed (瘫痪的), it's often because the brain has lost the ability to send signals to nerves and muscles in certain parts of the body. Neuralink hopes that one day, its system will be ableto send this information in a different way, allowing paralyzed people to use their arms or legs again.8. What does Neuralink aim to do?A. To make monkeys much smarter.B. To solve complex problems with monkeys.C. To create a device linking monkeys and people.D. To make people control things with their brains.9. How does the author introduce the process of the research?A. In order of time.B. By making a comparison.C. By giving examples.D. In order of space.10. What played an important role in the success of the research?A. The joystick.B. Artificial intelligence.C. The video game.D. The banana smoothie.11. Which is the most suitable title of the test?A. Neuralink Posts an Unusual VideoB. Disabled People Have a Bright FutureC. Monkey Plays Video Games with His MindD. Neuralink, a Creative and Competitive CompanyDFor years, life went something like this: We’d grow up in one place, head off to college, and then find a city to get a job and live there for a few years. The final goal was to find somewhere to settle down, buy a house, start a family, and begin the whole cycle all over again. But now some people are increasingly choosing to move from city to city throughout their entire lives, sometimes as frequently as every month.Just ask Alex Chatzieleftheriou, who has had a front-row seat watching this evolution unfold. Six years ago, he launched a startup called Blueground that rents out beautifully designed, fully furnished apartments for a month at a time, at rates that are cheaper than hotels. And it aims to make each one feel unique and comfortable,rather than standardized, like what you might find in a traditional hotel.Today, the company has 3,000 properties(房地产) in six U.S. cities, along with Dubai, Istanbul, London, Paris,and Chatzieleftheriou’s native Athens, and a staff of 400. With the helpof the Series B round of funding, the company landed $ 50 million, plus its previous total of $ 28 million, to continue its rapid expansion. It hopes to have 50,000 properties in 50 cities over the next three years.Chatzieleftheriou first came up with the idea for Blueground while he was working as a management consultant for McKinsey. “The accommodation of choice for consultants is the hotel,” he says. “I had to spend five years in hotel rooms, living in 12 different cities. I loved seeing the world, but I didn’t love feeling like I didn’t have a home.” And what’s more, hotels aren’t a particularly cost-effective solution for companies either. In Chatzieleftheriou’s case, McKinsey sometimes paid $ 10,000 or more for him to stay in a major city for a month.12. What does the author intend to tell in the first paragraph?A. A new lifestyle is appearing.B. Life is just like a circle for people.C. Most people are used to an easy life.D. People live in different places in life.13. What is the goal of Blueground?A. To compete with hotels.B. To create standardized hotels.C. To make renters feel at home.D. To rent out long-term apartments.14. What do we know about Blueground?A. It got a total investment of $ 78 million.B. Its business is anything but satisfying.C. It expanded to every corner of the world.D. It has 50,000 properties in 50 cities.15. What does the last paragraph focus on?A. High costs of hotels.B. Chatzieleftheriou’s former work.C Strengths of Blueground.D. The inspiration for Blueground.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。
