2019-2020学年中国人民大学附属中学分校高三英语二模试题及参考答案
2019-2020学年中国人民大学附属中学分校高三英语二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AWhat to Eat—and What to Skip—When It Comes to Takeout FoodIf the burden on your wallet doesn't bother you much, the effect your takeout habit can have on your waistline just might arouse your attention. Here's the best and worst of the lot for your belly.Steamed Vegetable Dumplings: Order This.When she orders Chinese, registered dietitian nutritionist Elisa Zied gets an order of steamed vegetable dumplings. "I often pair them with either chicken and broccoli in brown sauce（I ask for a little saucemade without sugar）or steamed shrimp dumplings," she tells us.Crab Wontons: Not That!When you deconstruct crab wontons, it's easy to see why they're a "Not That!" The inside is filled with crabmeat and cream cheese（which is just a fancy, spreadable fat）.The wonton is made of refined flour, egg and salt and the crispy（脆的）coating is a result of a deep oil bath.Peking Duck: Order This.Most of the fat from the skin flows out of the duck over the course of cooking, making this a healthier choice than most of the stir-fry dishes available. Order a side of steamed vegetables and serve it with a small scoop of brown rice. Done and done!Sweet and Sour Anything: Not That!Anything with “sweet and sour” in its title is a powerful cue that something has been deep-fried and covered in a sickly-sweet pink sauce. If you pair your selection with a side of rice, you're looking at a 1,000-calorie meal.Summer Roll: Order This.Summer rolls are steamed instead of fried—and typically filled with lean proteins and vegetables, making them a winning appetizer in our book. Pair them with an order of edamame（毛豆）and a broth-based soup for a satisfying, filling meal.Spring Roll: Not That!Spring=deep-fried, which is why we say to skip them! They're filled with fat and calories your belly doesn'tneed.1.What kind of cooking method should be skipped according to the text?A.Steaming.B.Stir-frying.C.Deep-frying.D.Boiling.2.Which of the following suits as a good starter for a meal?A.Chicken and broccoli.B.Steamed vegetable dumplings.C.Peking duck.D.Summer rolls.3.Where can the text be found?A.In a recipe.B.In a guidebook.C.In a science fiction.D.In a health magazine.BThe grocerystore might not be your favorite place to visit when you're at home, but is it ever fun when you're in another country? Honestly speaking, they're one of those strange little destinations that I like to sniff out everywhere I go, much as other travelers head toward clothing stores, libraries, coffee shops or galleries.The greatest beauty of the grocery store –– whether it's a supermarket or a tiny shop –– is that it gives you a glimpse into what local people buy to cook their own meals. This offers clues into their lifestyles and preferences, and into the agricultural and cooking practices of the country. I stare at the strange fruits and vegetables, the seafood, the cheese, the spices, the bread, and oh, the chocolate...always the chocolate!Being the environmental nerd（呆子）I am, I like paying attention to packaging, which can reflect people's attitudes towards environmental protection. Italy, for example, has a habit of requiring customers to bag their fruits and vegetables in plastic for weighing, while Sri Lanka leaveseverything loose in bins. In Brazil, everything is prepackaged in a layer of plastic.People in grocery stores tend to be friendlier. They smile, say hello, and sometimes ask questions, which can lead to great conversations. I had a further discussion with a teenaged cashier in Sri Lanka, over which bag of crunchy（松脆的）mix to buy. He insisted that the one labeled “spicy” would be too hot for me, but I told him I was willing to risk it. He laughed and we ended up talking about my favorite Sri Lankan foods for ten minutes.It's interesting then to come home and look at one's own local grocery store through new eyes. What would a visitor think? What stands out, and what do the food displays say about us as a culture? You might be surprised by what you realize.4. According to the author, what is the key benefit of visiting foreign grocery stores?A. Learning to cook foreign dishes.B. Making friends with local people.C. Buying cheaper food and souvenirs.D. Knowing local people and the country.5. What does the author show by mentioning some countries in paragraph 3?A. People's special lifestyles.B. People's shopping habits.C. People's environmental awareness.D. People's packaging methods.6. What can we infer from paragraph 4?A. Sri Lankans know a lot about food.B. Grocery stores are good social places.C. Grocery stores vary in different countries.D. Sri Lankans like to give strangers suggestions.7. Which of the following shows the structure of text? (P: paragraph)A. B.C. D.CIf you easily make mistakes when in a hurry, a new study from Michigan State University—the largest of its kind to date-found that meditation (冥想) could help you improve the situation.The research tested how open monitoring meditation (OMM)—or, meditationthat focuses awareness on feelings or thoughts as they unfold in one’s mind and body—alteredbrain activity in a way that suggested increased error recognition.“People’s interest in meditation is outpacing what science can prove in terms of effects and benefits.” said Jeff Lin, MSU psychology doctoral candidate and study co-author. “But it’s amazing to me that we were able to see how one session of a guided meditation could produce changes to brain activity in non-meditators.”“Some forms of meditation have you focus on a single object, commonly your breath, but open monitoring meditation is a bit different,” Lin said, “It has you tune inward and pay attention to everything going on in your mind and body. The goal is to sit quietly and pay close attention to where the mind travels without getting too caught up in the scenery.”Lin and his MSU co-authors—William Eckerle, Ling Peng and Jason Moser—hired more than 200 participants to test how open monitoring meditation affected how people detect and respond toerrors.The participants, who had never meditated before, were taken through a 20-minute open monitoring meditation exercise while the researchers measured brain activity through electroencephalography (脑电图), or EEG. Then, they completed a computerized distraction (分心) test.“The EEG can measure brain activity at the millisecond level, so we got precise measures of brain activity right after mistakes compared to correct responses,” Lin said. “A certain neural signal occurs about half a second after an error called the error positivity, which is linked to conscious error recognition. We found that the strength of this signal is increased in the meditators to controls.”“These findings show what just 20 minutes of open monitoring meditation can do to improve the brain’s ability to detect and pay attention to mistakes,” Moser said.8. What does the underlined word “altered” in paragraph 2 probably mean?A. Changed.B. Prevented.C. Started.D. Recorded.9. Why is open monitoring meditation different?A. It is just aimed at a single object.B. It clears your mind of everything.C. It gets too caught up in the scenery.D. It focuses on where the mind travels.10. What did the researchers do for the studyA. They hired people who had meditated before.B. They measured the participants’ brain activity.C. They reminded the participants to avoid errors.D. They had non-meditators design a distraction test.11. What is the best title for the text?A. Turn to OMM to Avoid Acting in a HurryB. You’re Able to Recognize Errors ConsciouslyC. Meditators’ Brain Proves Much More ActiveD. OMM Can Help You Make Fewer MistakesDJennifer Mauer has needed more willpower than the typical college student to pursue her goal of earning a nursing degree. That willpower bore fruit when Jennifer graduated from University of Wisconsin-Eau Claire and became the first in her large family to earn a bachelor's(学士) degree.Jennifer grew up on a farm in a family of 10 children. Her dad worked at a job away from the farm, and her mother ran the farm with the kids. After high school, Jennifer attended a local technical college, working to pay her tuition(学费), because there was no extra money set aside for a college education. After graduation, she worked to help her sisters and brothers pay for their schooling.Jennifer now is married and has three children of her own. She decided to go back to college to advance her career and to be able to better support her family while doing something she loves: nursing. She chose the UW-Eau Claire program at Ministry Saint Joseph's Hospital in Marshfield because she was able to pursue her four-year degree close to home. She could drive to class and be home in the evening to help with her kids. Jennifer received great support from her family as she worked to earn her degree: Her husband worked two jobs to cover the bills, and her 68-year-old mother helped take care of the children at times.Through it all, she remained in good academic standing and graduated with honors. Jennifer sacrificed(牺牲) a lot to achieve her goal, giving up many nights with her kids and missing important events to study. “Some nights my heart was breaking to have to pick between my kids and studying for exams or papers,” she says. However, her children have learned animportant lesson, witnessing their mother earn her degree. Jennifer is a first-generation graduate and an inspiration to her family—and that's pretty powerful.12. What did Jennifer do after high school?A. She helped her dad with his work.B. She ran the family farm on her own.C. She taught her sisters and brothers.D. She supported herself through college.13. Why did she choose the program at Ministry Saint Joseph's Hospital?A. To learn from the best nurses.B. To take care of her kids easily at night.C. To save money for her parents.D. To find a well-paid job there.14. What did Jennifer sacrifice to achieve her goal?A. Her health.B. Her chance of promotion.C Her reputation. D. Her time with family.15. What can we learn from Jennifer's story?A. Hard work pays off.B. Love breaks down barriers.C. Time is money.D. Education is the key to success.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
2019-2020学年中国人民大学附属中学分校高三英语第二次联考试题及答案
2019-2020学年中国人民大学附属中学分校高三英语第二次联考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ANational Disability Insurance Scheme (方案)The National Disability Insurance Scheme (NDIS) will transform the way Queenslanders with disability are supported and change the way disability services are funded and delivered.Under the scheme, Queenslanders with disability will have choice and control over how they access support and who delivers them. They will also have certainty that they will be supported throughout their lifetime to achieve their personal goals.The NDIS will have an effect on the following programs.School Transport Assistance Program for Students with DisabilityThe NDIS will not disrupt existing services for qualified students. The Queensland Government will also continue to provide school transport assistance for students with disability who are not qualified to receive funding via the NDIS.For more information about the School Transport Assistance Program, and to check your qualification, visit the Education and Training website.Taxi Subsidy (补助金) SchemeThe Queensland Governmenthas lengthened the Taxi Subsidy Scheme (TSS) membership for NDIS qualified members to 31 October, 2022. This will allow more time to solve transport support arrangements under the Commonwealth’s NDIS.You can find more information about the TSS and your qualification on the TransLink website.Disability Parking Permit SchemeNo changes will be made to the Disability parking permit scheme when the NDIS is introduced inQueensland. Current arrangements for this scheme will be maintained.You can find more information on this scheme, and check your qualification, on the Queensland Government website.Public Transport Concessions for People with DisabilityThere will be no change to concessions on public transport for people with disability when the NDIS is introduced inQueensland. TransLink will continue to ensure concessions are provided for disabled persons travelling on public transport inQueenslandwhen the NDIS is introduced.You can find more information about public transport discounts for people with disability, and check your qualification, on the TransLink website,1.Which program helps drive the disabled to and from school?A.Taxi Subsidy Scheme.B.Disability Parking Permit Scheme.C.Public Transport Concessions for People with Disability.D.School Transport Assistance Program for Students with Disability.2.What can we learn about Taxi Subsidy Scheme?A.The scheme is for parking permit.B.The existing membership can be effective for longer time.C.There is no change to current arrangements for the scheme.D.The NDIS will not break off existing services for qualified students.3.What do the four programs have in common?A.They are all related to transport.B.They are all largely affected by NDIS.C.They all can be checked on the same website.D.They all provide discounts for disabled persons.BIf you have ever tried to catch a resting butterfly, you know it is surprisingly difficult. A new study helps explain why.Previous research had suggested that a butterfly's overhead wing clap forces the insect forward. Researchers thought the wing clap likely formed a pocket of air that shoots out like a jet, but no one had tested that until now.To understand their flight, they placed six butterflies one at a time inside a wind tunnel which was filled with smoke and then used a laser to light up the smoke just behind the butterfly. Four high-speed cameras were placed in the tunnel to take photos of the movement of the butterfly and the-smoke as the butterfly was taking off. This let the researchers create a 3D picture of that air movement as the insect flapped its wings.They observed a total of 25 takeoffs by six butterflies. Each included up to three wing beats after takeoff.Thebutterflies proved more likely to clap their wings together during the first few wing beats than later in flight.The photos show that forces created by the wings give rise to a flight path. The butterflies rise as their wings move down and shoot forward as their wings move up. A wing clap on takeoff, paired with a quick tum, allowed the butterflies to fly away quickly. They also noticed the wings formed an air pocket just before clapping and that the wings' flexibility and this pocket improved the jet force created by the clap.“The study is exciting,” says Ayodeji Bode-Oke, a mechanical engineer in Charlottesville. That means “we have solved the longtime puzzle about how butterflies fly, and it proves nothing is impossible on the road of scientific research. I can't wait to learn about how the study might inform designs for small aerial vehicles.”4. Why was laser used in the experiment?A. To frighten the butterflies into lying.B. To help researchers observe the butterflies.C. To help take clear photos of air movement.D. To guide the butterflies through the smoke.5. What is the finding of the research-according to paragraph 5?A. Butterflies fly forward as wings move down.B. An air pocket forms after butterflies clap wings.C. Butterflies beat wings three times before taking off.D. Upward wing movements help butterflies fly forward.6. According to the writer, the finding of the research can be used for .A. helping catch a resting butterfly more easilyB. helping do research on other butterfly-like insectsC. helping provide inspiration for making small flying vehiclesD. helping widen the applications of small flying vehicle7. What can be the best title for the text?A. Why Can Butterflies Fly Like a Jet?B. How Can Butterflies Make Wing Claps?C. How Can Butterflies Make Quick Tums?D. Why Can Butterflies Run Away Quickly?CSonja Redding and her family were on their way home to Omaha, Nebraska, after a weeklong visit toWashington, D. C. with her two sons, one of whom, 5-year-old Xayvior, has autism(自闭症).Although all of the other flights had gone fine, Xayvior became angry during one of the flights, and Redding couldn’t calm him.“It felt like everyone on the plane was looking at us and got angry with my son, ” she wrote in a Facebook post after she got home. “I don’t know what to do when others just don’t understand that he is not just a kid with no discipline(自制力)，but a child with special needs who doesn’t know how to control himself.”The day was saved by Delta flight attendant(空乘人员)Amanda Amburgy. She tried to help Xayvior watch a movie, but when that failed, she offered to take him on a tour of the airplane.That worked, and soon the child was not only calm, but having a good time.“When they came back, Xayvior was much calmer and happier,” wrote Redding in the post，which now has 2,700 likes and over 500 shares. “I want to thank this Delta attendant. She didn’t judge, and she just showed love. We need more people like this in the world. ”It wasn’t long before Amburgy was told about the post.“ We’re there to help, and that’s what we want to do,” she said in an interview. “So, we always want to make anything easier for the family as well as other passengers.”She also shared what she felt when she read Redding’s story. “When I read it, it touched my heart. It’s something I would do for anyone on the plane, because that’s what I’m here for. It really made a difference in her life.”8. How did Redding feel on the plane?A. Tired.B. Uncomfortable.C. Very angry.D. Deeply afraid.9. What did Amburgy do to help the family?A. She asked the family to stay beside her.B. She asked the other passengers for help.C. She tried her best to calm the boy.D. She helped look after the other boy.10. Why did Redding post the story?A. To show her thanks.B. To help kids with autism.C. To get in touch with Amburgy.D. To share her travel experience.11. Which of the following words can best describe Amburgy?A. Proud.B. Honest.C. Hard-working.D. Warm-hearted.DPaper is one of our oldest, simplest and most important inventions. But it also presents a danger to the world in two important ways. First, the making of paper requires the loss of many millions of trees each year. And worldwide use of paper is expected to double in the next 40 years. Clearly, the planet cannot stand such a high rate of forest loss. The second great problem with paper is what happens once it is no longer useful. A large amount of wastepaper ends up in landfills, where it can produce harmful gases and finally contribute to global climate change.One simple solution can greatly reduce both of these problems: paper recycling. Instead of cutting down trees, recycle existing paper to feed the paper-making process.Paper is mainly made from cellulose (纤维素)，which can be used repeatedly in papermaking. Unfortunately, it also means that paper waste takes a surprisingly long time to break down in landfills. So far, trees are the only source(来源) of cellulose that can fill the great demand for paper products. Therefore, recycling paper is simply one of the best ways to save trees. Thanks to advances in processing, recycled paper need not be the dark-color1 edstuff many of us are familiar with. It now can offer the same print performance as non-recycled paper.Effective recycling requires a continuous effort from everyone at all levels of society. The way to begin is with education and understanding. Once enough people realize the need for recycling, more effective recycling systems can be developed.The need is real. The massive loss of trees affects everybody on earth. Everyone should do their part to recycle paper and encourage government and industry to do the same. The world will be a better place for it!12. What can we infer from the text?A. The use of recycled paper will double in 40 years.B. Recycling paper helps relieve global climate change.C. Wastepaper can easily break down in landfills.D. There are not enough landfills for wastepaper.13. What makes recycled paper more acceptable?A. The great demand of trees.B. The low processing cost.C. Its dark-color1 ed feature.D. Its improved print performance.14. What does the author propose?A. Punishing the act of cutting trees.B. Recycling paper.C. Improving recycling system.D. Promoting paper industry.15. How is the text mainly developed?A. By analyzing causes and effects.B. By offering research plans and data.C. By discussing problems and solutions.D. By comparing strengths and weaknesses.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。

An 85-year-old primary school has been lifted off the ground in its entirety and relocated using new technology named the “walking” machine.In the city’s latest effort to preserve historic structures, engineers used nearly 200 mobile supports under the five-story building. The supports act like robotic legs. They’re split into two groups which in turns rise up and down, imitating the human step. Attached sensors help control how the building moves forward.TheLagenaPrimary School, which weighs 7,600 tons, faced a new challenge — it’s T-shaped, while previously relocated structures were square or rectangular. Experts and technicians met to discuss possibilities and test a number of different technologies before deciding on the “walking machine”.Over the course of 18 days, the building was rotated 21degrees and moved 62 meters away to its new location. The old school building is set to become a center for heritage protection and cultural protection. The project marks the first time this “walking machine” method has been used inShanghaito relocate a historical building.In recent years,China’s rapid modernization has seen many historic buildingsrazedto clear land for skyscrapers and office buildings. But there has been growing concern about the architectural heritage loss as a result of destruction across the country.Shanghaihas beenChina’s most progressive city when it comes to heritage preservation. The survival of a number of 1930s buildings in the famous Bund district and 19th-century “Shikumen” houses in the repaired Xintiandi neighborhood has offered examples of how to give old buildings new life.

Elfdalian sounds nothing like the country's national language, Swedish, which press secretary Bjorm Rehnstrom said affected the language about 100 years ago. At that point, Elfdalian declined. Ulla Schitt, also a Ulum Dalska member, experienced the change while growing up in Alvdalen.“My parents spoke Efdalian with each other, and with my grandma and my aunts and uncles and everyone around,”Schit said. “But when they turned to me, they spoke Swedish.” Schitt said her parents spoke Swedish with her because that's what was spoken in schools.But people are getting creative in the fight to change that trend. Musicians are creating new songs with Elfdalian. Several children's books were also translated into EIfdalian, including Le Petit Prince by Antoine de Saint-Exupery. Additionally, Bjorm Rehnstrom helps run a popular Facebook group that offers courses in the Elfdalian language, where he offers lessons to the group's 1,800 global members from America, Australia, South America, Indonesia, Haiti and Cape Verde.The local government supports the teaching and preservation of Elfdalian. Bjom Rehnstrom said they eagerly paid for a sign that reads: “Welcome to Alvdalen” in Elfdalian. But the national government of Sweden is a different story. They currently consider Eidalian a dialect of Swedish, not its own language.Schitt said every time a language dies it is a sad moment. To her, losing Elfdalian would be an especially tragic (悲剧的) loss. “It's a part of our identity. It's part of our culture,” she said. “And if part of your identity and culture dies, a part of yourself dies.” Getting Elfdalian recognized as a language by the Swedish government, she added, is key to making sure that death doesn't come.12. Why was Ulum Dalska founded?A. To teach Swedish.B. To save Elfdalian.C. To improve Alvdalen.D. To help schools.13. Why Schitt's parents spoke Swedish with her?A. They could only speak Swedish fluently.B. Schitt longed to speak Swedish at home.C. Swedish was the language of schools.D. It was required by her school teachers,14. What can we infer from paragraph 4?A. Many people are trying to help to save Elfdalian.B. Songs in Elfdalian are becoming more popular.C. Le Petit Prince was translated into various languages.D. Courses in Eldalian are provided to the world freely.15. What does Schitt think of preserving Elfdalian?A. Satisfactory.B. Vital.C. Dangerous.D. Meaningless.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2019-2020学年中国人民大学附属中学高三英语二模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ALocated in the beautiful Sichuan Basin, Chongqing is a magical 8D city. The natural history and cultural scenery of the area provide children with learning opportunities because they can enjoy the many wonders of this area.Fengjie Tiankeng Ground JointTiankeng Diqiao Scenic Area is located in the southern mountainous area of Fengjie County. The Tiankeng pit is 666 meters deep and is currently the deepest tiankeng in the world. The scenic spot is divided into ten areas including Xiaozhai Tiankeng, Tianjingxia Ground, Labyrinth River, and Longqiao River. There are many and weird karst cave shafts, and countless legends haunt them.Youyang Peach GardenYouyang Taohuayuan Scenic Area is a national forest park, a national 5A-level scenic spot, and a national outdoor sports training base. Located in the hinterland of Wuling Mountain. The Fuxi Cave in the scenic spot is about 3,000 meters long, with winding corridors, deep underground rivers, and color1 ful stalactites. The landscape is beautiful.Jinyun Mountain National Nature ReserveJinyun Mountain is located in Beibei District of Chongqing City, about 45 kilometers away from the Central District of Chongqing City. The nine peaks of Jinyun Mountain stand upright and rise from the ground. The ancient trees on the mountain are towering, the green bamboos form the forest, the environment is quiet, and the scenery is beautiful, so it is called "Little Emei". Among them, Yujian Peak is the highest, 1050 meters above sea level; Lion Peak is the most precipitous and spectacular, and the other peaks are also unique.Chongqing People's SquareChongqing's Great Hall of the People, one of the landmarks of Chongqing, gives people the deepest impression than its magnificent appearance resembling the Temple of Heaven. It also uses the traditional method of central axis symmetry, with colonnade-style double wings and a tower ending, plus a large green glazed roof, large red pillars, white railings, double-eave bucket arches, and painted carved beams.1.How deep is the Tiankeng Ground Joint?A.666mB.3,000mC.45kmD.1050m2.Which of the following rocks can you see in Youyang Peach Garden?A.LimestoneB.StalactiteC.MarbleD.Quartzite3.Which attraction is closest to downtown Chongqing?A.Fengjie Tiankeng Ground JointB.Jinyun Mountain National Nature ReserveC.Chongqing People's SquareD.Youyang Peach GardenBIf you've ever had a dog, you know just howdeep a connection you can develop with “man's best friend”. But a dog's life is much shorter than humans, about 12 to 15 years long, which means every dog owner has to go through the heartbreaking moment when their loving pet passes away.Why not make a clone of that dog then? This is the solution offered by a South Korean company, Sooam Biotech Research Foundation. The company has already successfully cloned at least 400 dogs, mostly for US customers, ever since it pioneered the technique in 2005. Now, Sooam Biotech has introduced its business toUKdog owners as well, offering them dogs that look just like their lost ones.To clone a dog, researchers first need to take a skin cell from a living dog or one that has just died. Meanwhile,another dog is selected to supply an egg. Researchers then replace the DNA in the egg with that from the skin cell and implant the egg into the womb (子宫) of a female dog. The egg grows into a puppy over the following two months. The whole process takes less than a day, but it comes at a shockingly high price — around ￡63,000.But if you can't afford it now, you can also save the cell in a laboratory andaccess it at a later date.However, magical as cloning might sound, there is no guarantee that the cloned dog will be a perfect copy of the original one. Just like identical twins of humans, they share the exactly same DNA but there will still be small differences between them. “The spots on a Dalmatian (斑点狗) clone will be different, for example” Insung Hwang, head of Sooam Biotech, told The Guardian.Dog owners will also have to accept the fact that personality is not “cloneable”. Apart from genes, personality is also determined by upbringing and environment, which are both random elements that cloning technologies simply cannot overcome, Professor Tom Kirkwood atNewcastle University,UK, told The Telegraph.Perhaps bringing our dogs back by cloning is not the best way to remember them after all.Kirkwood, a dog owner himself, pointed out, “An important aspect of our relationship with them is coming to terms with the painof letting go.”4. What service does Sooam Biotech Research Foundation offer?A. Making copies of pet dogs.B. Giving pet dogs identical twinsC. Helping dogs give birth to more puppies.D.Helping dog owners love their dogs more.5. Which order is correct in the dog cloning process?a. An egg is taken from another dog.b. A skin cell is taken from the pet dog.c. The egg grows into a puppy in two months.d. The egg is placed in the womb of a female dog.e. The DNA in the egg is replaced by the DNA from the skin cell.A.a→d→b→e→c.B. a→e→b→d→cC. b→a→d→e→c.D. b→a→e→d→c.6. What can we learn about dog cloning from the passage?A. It has not been put into practice until recently.B. It is very popular among US andUKpet owners.C. It might not give the owners an exactlysame dog.D. It is very expensive and usually takes half a year to complete.7. What doesKirkwoodthink of dog cloning?A. He disagrees with it.B. He supports it.C. He is curious about it.D. He thinks it unbelievable.C“We are running out of space and the only places to go to are other worlds... Spreading out may be the only thing that saves us from ourselves. I am convinced that humans need to leave Earth.” These are the words of the famous scientist Stephen Hawking, spoken at a science festival inNorwayin 2017, a year before his death.Hawking was not alone in this view. Many experts feel that the only way for humanity to last far into the future is to colonize other planets. That way, if an asteroid, a terrible disease, nuclear war, or some other disaster strikes Earth, civilization as we know it would still have a chance. Mars is one of the most tempting destinations. NASA, theUnited Arab Emirates, the private company SpaceX, and the organization Mars One all have plans tosend humans there. “Either we spread Earth to other planets, or we risk going extinct, SpaceX founder Elon Musk said at a conference in 2013.But not everyone agrees that colonizing Mars or any other planet is such a great plan. The most common argument against going is that it’s just too expensive or dangerous. It will take huge amounts of money and other resources just to get people there, let alone set up a place for them to live. It’s not even clear if humans could survive on Mars. One of the biggest dangers there is deadly radiation that bombards the planet.Maybe all the time and money people would pour into a Mars mission would be better spent on more urgent projects here on Earth, like dealing with poverty or climate change. Some experts argue that handling a problem like an asteroid strike or disease outbreak while staying here on Earth would be much easier and less expensive than surviving on a new planet.In addition, moving to a new planet could harm or destroy anything that already lives there. Mars seems uninhabited, but it could possibly host microbial life. Human visitors may destroy this life or permanently change or damage the Martian environment. Some feel that’s too much of a risk to take.What do you think? Should humans colonize outer space or stay home?8. What can be inferred from the passage?A. Many experts insist that humans should take the risk.B. Mars is the most attractive destinations for human beings.C. Hawking firmly believes the only way to save humans is moving to Mars.D. All the other experts don’t agree with Hawking’s idea.9. Why do some experts disagree with the plan to colonize Mars?A. It will cost much more money to settle on Mars than on Earth.B. It is too long a distance from the Earth to the Mars.C. Human visitors will bring diseases to Martian environment.D. The deadly radiation that bombards the planet is the biggest danger.10. What’s the writing purpose of the passage?A. To raise people’s awareness of protecting the environment.B. To present different opinions on whether to move to the Mars.C. To arouse readers’ reflection on whether to colonize outer space.D. To inspire people to deal with the environmental problems.11. In which section of a magazine is the passage most likely from?A. Fiction.B. Current affairs.C. Social Studies.D. Science.DMany of us were delighted to learn that a high school senior Kwasi Enin was accepted to all eight Ivy League universities. To our surprise, he wasn't excited as expected, but appeared extra calm. He announced that he would revisit the universities to find the best suitable in music or medicine. He also wanted to compare their financial aid packages.Kwasi's success story is rare, but his reaction is not. After the admission letters arrive at home, students have 30 days to really think about what kind of school would help them grow as a person, which school would best prepare them for the future, and at which school they would be happiest. And they also have to think about whether they can afford the school they choose.But how to answer the questions about which school is the best suitable university? Some young people are attracted to large universities with great school spirit and a list of offerings. But besides those advantages, many of these universities focus on graduate work and research, with undergraduates taught mostly by part-time instructors. Others are attracted to smaller boarding schools with discussion-based classes. But some of these schools will have much limitation for students who want a high-energy city life experience.Many students today seem to think they should pick the university where they will get the diploma that will help them get the most highly paid job. This is a sad misunderstanding of what a college education should provide.A good college education should prepare them to overcome any difficulty andthrivein society. It helps them to form the habit of creative mind and spirit that will continue to develop far beyond their university years. So when you choose college, you should consider if it is filled with useful learning to help create new spaces for different possibilities of growth.12. What can we know about Kwasi Enin from paragraph 1?A. He was from a very poor family.B. He would choose the top university.C. He was too excited to calm himself at the good news.D. He considered his interests when choosing his university.13. What can you infer from paragraph 2?A. Few students can be admitted to university.B. Many students face the choices like Kwasi.C. Top universities are the first choice for most students.D. American students can afford their university by themselves.14. Which of the following can best explain the underlined word “thrive” in paragraph 4?A. FailB. SucceedC. ResearchD. Work15. What should the best university be like according to the text?A. Very large and have good instructors.B. Small boarding schools with discussion-based classes.C. It will offerthe diploma to get the most highly paid job.D. It will help continue to develop far beyond university years.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2019-2020学年中国人民大学附属中学高三英语二模试卷及答案
2019-2020学年中国人民大学附属中学高三英语二模试卷及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ABob and Sue Harvey spent nine years as resident fellows in a dormitory at Sanford and in their bookVirtual Reality and The College Freshman, they write “The Freshman oftenfaces an identity problem during the first semester.” College is a more pressured environment than it used to be, in part because the academic gap between high school and college has increased. Many college freshmen have never had to make independent decisions about sex, drugs and alcohol. Most don’t know how to manage their time or money. They often feel lonely and overwhelmed, resulting in anxiety and depression.Nancy Corbin, director of clinical service for student-counseling (咨询) services at Iowa State University, says her office is seeing a significant increase in requests for counseling from freshmen who are having trouble making the adjustment to college life. She says older teenagers increasingly lack the skills to deal with personal problems that aren’t easily defined or fixed. And they get homesick but have a hard time admitting it.Parents and high schools can make things easier on freshmen by preparing them differently. For example, by teaching them to budget their hours and dollars. The Harveys think high schools should offer a college-life course. “Parents need to focus more on relationship and personal issues and less on how many sheets and towels to take,” they say. Many homesick freshmen think they’ll be regarded as failures if they come home before Thanksgiving. So parents can help by letting them know they’re welcome to return if they feel the need. In the meantime, parents have to find new ways to keep in touch with their college kids. One of the best ways is e-mail. It’s less unpleasant and less expensive than constant phone calls and is more likely to be answered than a handwritten letter.1. Why is the first semester difficult for freshmen in college?A. Because they often fail in exams.B. Because they lack time and money.C. Because they are too homesick to make new friends.D. Because they have to settle personal issues on their own.2. In the last paragraph, it is suggested that ________.A. parents should stop buying anything for their kidsB. parents should develop a good relationship with their kidsC. parents should be taught how to send e-mails to their kidsD. parents should work with high schools in college-life courses3. Which of the following might be the best title for the passage?A. Hard Life of College FreshmenB. Approaches to Trouble in CollegeC. Freshmen’s Adaptation ProblemsD. A Strange Phenomenon in CollegeBTen years ago, I set out to examine luck. I wanted to know why some people were always in the right place at the right time, while others consistently experienced ill fortune. I placed advertisements in national newspapers asking for people who felt consistently lucky or unlucky. Hundreds of extraordinary men and women volunteered for my research. Over the years I have interviewed them, monitored their lives and had them take part in various experiments.In one of the experiments, I gave both lucky and unlucky people a newspaper, asking them to look through it and tell me how many photographs were inside. I had secretly placed a large message halfway through the newspaper, saying, “Tell the experimenter you have seen this and you will win $50.” This message took up half of the page and was written in type that was more than two inches high. It was staring everyone in the face, but the unlucky people tended to miss it and the lucky people tended to spot it.Unlucky people are generally more nervous than lucky people, and this anxiety affects their ability to notice the unexpected. As a result, they miss opportunities because they are too focused on looking for something else. They go to gatherings concentrating on finding their perfect partners and miss opportunities to make good friends. They look through newspapers determined to find certain types of job advertisements and miss other types of jobs.Lucky people are more relaxed and open, and therefore see what is there rather than just what they are looking for. My research eventually showed that lucky people are skilled at noticing opportunities, make lucky decisions by listening to their intuition (直觉), are open to new experiences, and adopt a never-say-die attitude that transforms bad luck into good luck.4. What’s the purpose of the author’s research?A. To discover what luck means to people.B. To find lucky people and unlucky people.C. To distinguish between good luck and bad luck.D. To figure out why people are always lucky or unlucky.5. Why did the unlucky people miss the message in the experiment?A. There was too much information to be read in detail.B. They were too focused on looking for photographs.C. It took too much time to go through newspapers.D. The words were too small to be noticed.6. What leads to lucky people’s good fortune?A. Their ability to spot opportunities.B. Their ability to become relaxed.C. Their ability to communicate.D. Their ability to make friends.7. What’s the key message of the last paragraph?A. What lucky people are looking for.B. How lucky people generate good luck.C. What lucky people can do with opportunities.D How lucky people transform bad luck into good luck.CAn afternoon nap(午睡)is one of the joys of life, although too much napping could signal all is not well. In some cultures, people will have a daily nap — thisis fine. The warning comes when people start sleeping during the daytime, when they did not before. There is certainly a good reason to believe that daytime sleepiness — as in the Alzheimer's study — can be a marker of an underlying condition.For most people, napping during the day is mainly a sign that you are not getting enough sleep at night, says Dr. Neil Stanley, a sleep expert. "If you feel sleepy during the day, you should think about taking a nap. That is what the body needs — it doesn't need to be kept awake with caffeine, it needs sleep. "The feeling to notice is "sleepiness", he says, not "tiredness", which could be more psychological and linked to stress.So how do you nap well? The key thing, says Stanley, is how long your nap lasts. Choose either a 20-or 90-minute nap. "When you fall asleep, you'll quickly go through the lighter stages of sleep into your first period of deep sleep. You don't want to wake up in deep sleep because that's when you wake and feel worse than you did before. "Napping for 20 minutes means you will wake up before you go into deep sleep; napping for 90 minutes means you'll complete a sleep cycle.Once you factor in the time it takes to fall asleep — some people are better at napping than others but, says Stanley, "a healthy adult will fall asleep in between 5 and 12 minutes" — you can set an alarm, allowing a 30- to40-minute period for a short nap, and up to two hours for a longer one.A good time to nap is during the body's natural dip in the afternoon, between 2 pm and 4 pm. "You don't really want to be napping much pastthatbecause then you are going to be eating into your night-time sleep," Stanley says. The point, he stresses, is to get good night-time sleep, which would ensure you probably don't need to nap at all.8. What does an afternoon nap indicate for most people?A. Caffeine addiction.B. Psychological stress.C. Insufficient night sleep.D. Potential physical illness.9. What is the key to a good nap?A. Duration.B. Surroundings.C. Health.D. Stages.10. What does the underlined word "that" in the last paragraph refer to?A. A 30- to 40- minute period.B. Between 2 pm and 4 pm.C. Between 5 and 12 minutes.D. A 20- to 90-minute period.11. Which of the following can be the best title for the text?A. Why to phase a napB. When to take a good napC. What to learn from a napD. How to have a successful napDThe man who invented the World Wide Web a few decades ago is calling for major changes to make it better for humans. In an open letter published on Tuesday, Berners-Lee said that the web was used by half the world's population.Berners-Lee said the web had clearly created great opportunities for humans to progress and had made life easier for millions of people. Actually, it also has offered opportunities to groups traditionally not heard a new voice in society. However, he added that the web had also provided new ways for cheats to commit crimes (犯罪).“Against the background of news stories about how the web is misused, it's understandable that many people feel afraid and unsure if the web is really a force for good,” he wrote.Berners-Lee created a group called the World Wide Web Foundation. He islooking for help from governments, companies and people to become more involved in shaping the web to do more good for humans. His actual plan is called the “Contract (合同) for the Web”.Under this contract, governments are called on to take steps to makesure all people can connect to the Internet and that personal privacy is respected. Businesses are asked to keep the Internet prices low so morepeople can use the web. In addition, companies should respect privacy and develop technologies that aim to put people first.The plan also calls on people to create materials for the web and work with others to make sure that is rich, quality information for everyone. Besides, people should seek to “build strong communities that respect personal speech and human equality.” “The path to make the Internet better is the responsibility of everyone who uses it,” Bermers-Lee added, “Making big changes will not be easy, but will be very well worth it in the end.”12. What does Berners-Lee think of the World Wide Web?A. It is his greatest regret.B. It stops the progress of humans.C. It needs improving.D. It does more harm than good.13. What's wrong with the web according to Berners-Lee?A. It is misused for bad purposes.B. It is misunderstood by all people.C. It blocks out a new voice in society.D. It is expensive for half the world’s population.14. What are governments called on to do under the “Contract for the Web”?A. Put technology first.B. Create materials for the web.C. Popularize the Internet.D. Make the Internet free of charge.15. What should people do with the Internet in Berners-Lee's opinion?A. Be responsible for it.B. Absolutely reject it.C. Completely rely on it.D. Be unconcerned about it.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2019-2020学年中国人民大学附属中学分校高三英语二模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AUNUSUAL ATTRACTIONS ON THE WATERBangkokFloating MarketsThere are many floating markets where goods are sold from boats. While modem markets are more popular, floating markets still are huge attractions for local tourism. In Bangkok Floating Markets,Thailand, one of the most popular ones, any visitors can buy local foods and traditional hand-made souvenirs.Bregenzer Festspiele（Opera festival）The Bregenz Festival is held every year from July to August inVorarlberg,Austria. It has the world's largest stage on the water. The performances are different every year but they are usually united by one theme. The decorations（装饰）are very impressive and are worth seeing.Viva, ArtificialIslandArtificial islands are not something new. What makes this island special is that . it is floating. Viva is the largest out of three man-made islands along with Vista and Tera, all situated inSeoul,South Korea. The island weighs 2,000-tons and is technically a buoy（浮标）.The island unfortunately is not carbon-neutral（碳中和）but it has solar panels which can generate electricity to power the hall, restaurants and shopping malls. MarinaBayFloating Platform StadiumThis stadium was built as a temporary solution while Singapore National Stadium was rebuilt. Now it is usedfor different sporting events, concerts, and festivals. In particular, it was once used for the opening and closing ceremonies during the 2010 Summer Youth Olympics.1. What can visitors do at Bangkok Floating Markets?A. Performing.B.Boating.C. Shopping.D. Swimming.2. What do you know about Viva?A. It is the biggest island inSouth Korea.B. It has the equipment to harness solar energy.C. It is the largest floating stage on the water.D. It is a man-made island only for low-carbon life.3. Which attraction should you choose to watch a basketball match?A. Bangkok Floating Markets.B. Bregenzer Festspiele.C. Viva, ArtificialIsland.D.MarinaBayFloating Platform Stadium.BWhen rescuers were called to rescue a “little owl”, they did not expect to find one that was too fat to fly. A concerned citizen first spotted the poor bird lying helplessly. Even Rufus Samkin, whose team then took the team in on Jan.3, believed the bird to be injured. There were no wounds to be found, however, causing experts to believe the female owl was simply too wet to fly.But it was only after a thorough drying-off and complete checkup that they noted the real issue. The rescuers weighed the owl and concluded that she was “simply extremely obese” and couldn’t take off. This additional weight left her unable to fly, though experts began to wonder how she got so fat in the first place. Because it’s rather unusual for wild birds to reach such a state, they decided to keep her a few weeks and monitor her.In the end, the rescuers assessed that it was simply a case of “natural obesity”. December 2019 was quite warm, which meant that there were many insects for the bird to feast upon. Indeed, the owl was discovered in a field that was “filled with field mice” due to the usual climate. “It’s been very mild here, and the owl is able to find foods easily,” Samkin explained. With the sudden food, “she ly ate much and got very fat. She had a lovely time, but went too far.”The researchers consequently put the owl on a “strict diet” so she could shrink to a more “natural weight”. She was even put on a bit of exercise and encouraged to fly around. In the end, the bird was sent flying gracefully off into the British countryside at a much healthier and happier weight. Hopefully, this owl won’t come upon another feast of field mice—unless she wants another few weeks at the fat camp.4. What did people think happened to the owl at first?A. She was hurt.B. She was trapped.C. She was hungry.D. She was wet.5. Why was the bird unable to fly?A. She needed a thorough checkup.B. She should be given a drying-off.C. She was completed overweight.D. She was simply extremely strong.6. What made the owl have enough foods?A. The especially warm weather.B. The reducing number of insects.C. The rich fields growing crops.D. The lovely time the bird enjoyed.7. How did the owl loseits weight?A. Going on a diet and exercising.B. Flying in the British countryside.C. Visiting that fat camp again.D. Enjoying her wonderful feast freely.CUnderstanding the link between a clean environment and human life is not a new concept. In fact, it was noticed as early as ancient Rome. Today we see how green living has infiluenced our everyday lives. There is a growing community of people who embrace a zero waste lifestyle and make changes to the way they live to reduce their carbon footprint.Living a zero waste lifestyle means doing one’s best to achieve the aim of not sending anything to a landfill. People who adopt this lifestyle ultimately cut down on their waste by reducing what they need and want. They reuse what they own, sending few things to be recycled.Many people who adopt the zero waste lifestyle claim to be frustrated by the many harmful chemical substances found in beauty and cleaning products. They also find the uses of disposable items and excessive packaging. For example, how many times have we had to peel away layers of plastic wrap and cardboard before finally taking out the item which we had bought? Instead of buying pre-packed food and goods, those who identify with the zero waste philosophy tend to shop in stores that allow them to make purchases and bring their own cloth bags and glass jars to store their purchases.Many people may have the misconception that it is easier to live a zero waste lifestyle in the West. Nevertheless, Malaysian environmental journalist, Ms. Aurora Tin, has proven that a zero waste lifestyle is possible even in the Asian context. Instead of going to the supermarket to buy pre-packaged foods, Ms. Tin now visits the wet market and brings her own bags for vegetables. She has even stopped using store-bought toothpaste and makes her own toothpaste from coconut oil and baking soda. This lifestyle may be too big a change for the average person, but we could follow her suit to make gradual changes to our own lives.8. Which of the following is a zero waste lifestyle?A. Bringing a resuable container to take away food.B. Choosing appliances that cost less money.C. Turning off a device to stop using power.D. Classifying the garbage before throwing it away.9. What may disappoint a person who adopts a zero waste lifestyle?A. Recycable carboard.B. Excessive packaging.C. Glass jars to store purchases.D. Natural substances in cleaning products.10. What is the main idea of the last paragraph?A. How do people live a zero waste lifestyle.B. Why Ms. Tin chooses to live a zero waste lifestyle..C. We can also practice a zero waste lifestyle in Asia.D. It is easy to live a zero waste lifestyle in the West.11. What is the best title of the passage?A. Living a zero waste lifestyle.B. Going green ismore than a fashion.C. A zero waste lifetyle is easy to achieve.D. Making environmentally-conscious decisions.DCuckoos don’t bother building their own nests—they just lay eggs that perfectly imitate those of other birds and take over their nests. But other birds are wishing up, evolving some seriously impressive tricks to spot the cuckoo eggs.Cuckoos are often know asparasites, meaning that they hide their eggs in the nest of other species. To avoid detection, the cuckoos have evolved so that eggs seem reproduction of those of their preferred targets. If the host bird doesn’t notice the strange egg in its nest, the little cuckoo will actually take the entire nest for itself after it comes out, taking the other eggs on its back and dropping them out of the nest.To avoid this unpleasant fate for their young, the other birds have evolved a few smart ways to spot the fakes, which we’re only now beginning to fully understand. One of the most amazing finds is that birds have an extra colour-sensitive cell in their eyes, which makes them far more sensitive to ultraviolet wavelengths and allows them to see a far greater range of colours than humans can. This allows cautious birds to detect a fake egg which might be exactly the same to our eyes.Fascinatingly, we’re actually able to observe different bird species at very different points in their evolutionary war with the cuckoos. For instance, some cuckoos lay their eggs in the nests of the redstarts. The blue eggs these cuckoos lay are practically alike to those of the redstarts, and yet they are still sometimes rejected. Compare that with cuckoos who target dunnocks. While those birds lay perfectly blue eggs, their cuckoo invaders just lay white eggs with brown irregular shaped spots. And yet dunnocks barely ever seem to notice the obvious trick.Biologists suspect these more easily fooled species like the dunnocks are on the same evolutionary path as the redstarts, but they have a long way to go until they evolve the same levels of suspicion. What’s remarkable is that the dunnocks fakes are so bad and the redstart ones so good, and yet cuckoos are still more successful with the former than the latter.It speaks to just how thoroughly a species’ behavior can be changed by the pressures of natural selection, or it might just be a bit of strategic cooperation on the part of the dunnocks. Biologists have suggested that these birds are willing to tolerate a parasite every so often because they don’t want to risk accidentally getting rid of one of their own eggs.12. This passage can be most likely found in a ________.A. science surveyB. nature magazineC. zoo advertisementD. travel journal13. What does the underlined word “parasite” in paragraph 2 most probably refer to?A. Animals that work together to raise young.B Small harmful animals such as worms or mice.C. Animals that can adapt to changing environments.D. Animals which live on or inside other host animals.14. Which of the following is TRUE about the dunnock according to the passage?A. It is colour-blind and therefore cannot identify foreign eggs in the nest.B. It can easily remove cuckoo eggs from the nest because fakes are so bad.C. It is a host bird that is more likely to raise a cuckoo chick than the redstart.D. It is unable to evolve and hence accepts cuckoo eggs that appear in the nest.15. Which of the following can be inferred from the passage?A. Dunnocks may eventually learn to recognise foreign eggs.B. Redstarts seem to be less suspicious compared to dunnocks.C. Cuckoo birds are good at taking responsibility for their own young.D. It is very easy for cuckoos to imitate the colouring of the dunnock’s egg.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2019-2020学年中国人民大学附属中学分校高三英语二模试卷及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AObesity (肥胖症) is becoming a problem in our busy society, and almost one in three American adults is now considered to be obese. Children obesity is alsoat an all-time high.Obesity means being very overweight. If you are obese, you have too much bodyfat. If you eat more food than your body can use, this will make you put on weight. Food that your body does not need will be stored as fat by your body.The following are the major factors that increase the risk of obesity.What you eat plays a major role in weight gain. Eating a lot of fast food such as hamburgers, sweet drinks, ice creams and other sweet food can increase the risk of becoming obese.If you do not do enough exercise, you will put on weight as the food you eat is not being used to make energy for physical activities.The chances of you being obese are greater if your parents are obese.There are many psychological factors that cause people to eat too much. People who are worried, unhappy or bored will often eat to make themselves feel better. This is known as comfort eating.Age is another factor, as you tend (趋于) to be less active when you get older. When you get older, you need to eat less, and if you do not eat less, you will put on weight. Obesity can cause many health problems such as heart problems, high blood pressure and many other serious medical conditions.1. The underlined sentence in paragraph 1 means that ____.A. obesity does not do harm to health.B. there are more obese children than before.C. all the American children are obese.D. there are less obese children in the USA.2. According to the passage, there are ____ major factors that increase the risk of obesity.A. threeB. fourC. fiveD. six3. What will the writer most probably talk about after the last paragraph?A. How to avoid obesity.B. How to live in the busy USA.C. What illnesses are caused by obesity.D. How doctors treat heart problems.BSix Neanderthals who lived in what is now France were eaten by their fellow Neanderthals some 100,000 years ago, according to fearful evidence of the cannibalistic (食人的) event discovered by scientists in a cave in the 1990s. Now, researchersmay have figured out why the Neanderthals, including two children, became victims of cannibalism: Global warming.While previous studies have examined Neanderthal remains to find proof of cannibalistic behavior, this is the first study to offer clues as to what may have led Neanderthals to become cannibals. Scientists found that rapid changes in local ecosystems as the planet warmed may have wiped out the animal species that Neanderthals ate, forcing them to look elsewhere to fill their stomachs.The researchers examined a layer of sediment (沉积物) in a cave known as Baume Moula-Guercy, in southeastern France. In that layer, charcoal (碳) and animal bones were so well-preserved that scientists could reconstruct an environmental picture representing 120,000 to 130,000 years ago. They discovered that the climate in the area was likely even warmer than it is today, and that the change from a cold, dry climate to a warmer one happened quickly. “Maybe within a few generations”, study co-author Emmanuel said. As the animals that once populated the landscape disappeared, some Neanderthals ate what they could find — their neighbors.Cannibalism is by no means unique to Neanderthals, and has been practiced by humans and their s “from the early Palaeolithic to theBronze Age and beyond,” the study authors reported. The behavior adopted by the starving Neanderthals in the Baume Moula-Guercy should therefore not be viewed as “a mark of bestiality (兽性) or sub-humanity”, but as an emergency adaptation to a period of severe environmental stress, according to the study.4. What does the study mainly focus on?A. The social behavior of Neanderthals.B. The reason for cannibalism among Neanderthals.C. The climate change in southeasternFrance.D. The influence of global warming on ancient animals.5. What can possibly be used to describe the climate in southeasternFrance120,000 to 130,000 years ago?A. It was no warmer than it is today.B. It was first warm while later cold and dry.C. Its change was mild and went through quite a long process.D. Its change is a chief factor contributing to cannibalism.6. Which of the following might the study authors agree with?A. Neanderthals’ cannibalism showed their bestiality.B. Cannibalism was actually a measure the Neanderthals had to adopt to survive.C. Neanderthals’ cannibalism guaranteed their rule over other tribes.D. Only Neanderthals were found to have cannibalism in human history.7. Where can you most possibly find this passage?A. In a science journal.B. In a travel brochure.C. In a history book.D. In a geography book.CThe regular world presented to us by our five senses — you could call it reality 1.0 — is not always the most user-friendly. We get lost in unfamiliar cities; we meet people whose language we don’t understand. So why not try the improved version: augmented reality（AR）or reality 2.0 ? AR technology adds computer-produced images on the real world via a mobile phone camera or special video glasses.Early forms of AR are already here — smart phones can deliver information about nearby ATMs and restaurants and other points of interest. But that’s just the beginning. A few years from now the quantity of information available will have increased hugely. You will not only see that there’s a Chinese restaurant on the next block, but you will be able to see the menu and read reviews of it.This is where the next revolution in computing will take place: in the interface（界面）between the real world and the information brought to us via the Internet. Imagine bubbles floating before your eyes, filled with cool information about anything and everything that you see in front of you.Let’s jump ahead to ten years from now. A person trying to fix a car won’t be reading a book with pictures; he will be wearing a device that projects animated 3D computer graphics onto the equipment under repair, labelling parts and giving step-by-step guidance.The window onto the AR world can be a smart phone or special video glasses. But in ten years’ time these will have been replaced by contact lenses(隐形眼镜) with tiny LEDs, which present something at a readable distance in front of eyes. So a deaf person wearing these lenses will be able to see what people are saying.The question is, while we are all absorbed in our new augmented reality world, how willwe becommunicating with each other?8. What is the text mainly about?A. The relationship between reality 1.0 and reality 2.0.B. Different forms of the AR technology.C. The next information technology revolution.D. The popularity of the AR technology.9. Which of the following will AR technology support according to the text?A. To pay for things online conveniently.B. To play online games merrily.C. To offer information efficiently.D. To communicate with others socially.10. What are Contact lenses with tiny LEDs used for?A. Show texts and images.B. Protect people’s eyes.C. Help deaf people communicate.D. Replace smart phone.11. What’s the author’s attitude towards the AR technology?A. Indifferent.B. Critical.C. Concerned.D. Favourable.DIt all happened one afternoon in Carl's backyard a few years ago. We had just finished playing stickball, and I was about to go home.“Wait a minute,” Carl yelled. He ran into his house and cameback with a book for me to take home and read. All he said was, “See if you like it.”I said ly nothing. I kept the book for a couple of weeks and then returned it unread. Carl never asked me if I liked it or not. During the following two years Carl lent me three more books. Each time I returned them unread.A few days after graduating from high school, Carl asked, “Benny, which college are you going to?”“I'm not going to college.” I said.“Why not?” he asked.“Because my father can't afford the tuition (学费).” I answered.“Is that it?” Carl asked. “Yes,” I said.I lied. I had no intention of going back to school now that I was out. The following day, Carl knocked on my door and handed me a check for seventy-five dollars from his father along with the bookMartin Eden.“I think thatshould do it.” he said.Once again I was in shock. I was working full-time in my brother's bakery. I attended two classes atWayneUniversitypart-time at night. Halfway through the semester, after receiving failing grades on exams and essays, I decided there was no way I would ever become a good student and get satisfactory grades. I dropped out of college.One day, curious, I picked up the book, thinking Carl was trying to tell me something. Despite difficulty, I pressed on. By the time I finished the book, I understood why: the main character, Martin Eden, had my own poor educational background, but managed to educate himself and become a published author.12. What do we know about the author?A. He often told lies.B. He quit school unwillingly.C. He had thought little of education before.D. He became a published author.13. What kind of person is Carl?A. Caring.B. Emotional.C. Stubborn.D. Cautious.14. What message does Carl want to convey?A. Reading makes a rich man.B. Reading is the journey of the soul.C. Reading makes a person better known.D.Readingopens up new opportunities.15. What is the best title for the text?A. A strong desire for collegeB. A wish for better educationC. A wise friendD.

2019-2020学年中国人民大学附属中学西山学校高三英语二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AShopping centers，stadiums and universities may soon have a new tool to help fight crime.ACaliforniacompany called Knightscope says its robots can predict and prevent crime. Knightscope says the goal is to reduce crime by half in areas the robots guard.William Santana Li is the chief executive officer of Knightscope. He says，"These robot security guards will change the world. Our planet has more than seven billion people on it. It's going to quickly get to nine billion people. The security equipmentthat we have globally is just not going to develop that fast. The company's Autonomous Data Machines can become the eyes and ears of law enforcement（执法）.""You want them to be machines plus humans. Let. the machines do the heavy and sometimes dangerous work and let the humans do the strategic decision-making work，so it's always working all together."The machines do not carry weapons but they have day and night video cameras which are able to turn 360 degrees and can also sense chemical and biological weapons.Some people may become concerned about their privacy, especially in connection with the video recordings. Some people may worry that such recordings will appear on the Internet. Eugene Volokh, a law professor at the UCLA School of Law, says the machines have to be used in the right way and it will be interesting to see how state laws deal with this kind of video.William Santana Li says there is a long waiting list for the robots in theUS. Workers in the company are working overtime to meet the demands of the market. At least 25 other countries are also interested in these robot security guards.1. What can this new tool do for humans?A. Make strategic decisions.B. Keep watching day and night.C. Carry heavy weapons.D. Stop crime autonomously.2. Why are some people worried about the new robots?A. Their privacy may be let out.B. The robots are very expensive.C. Robots will replace humans.D. They will be out of work soon.3. Which of the following can be the best title of the text?A. Robots Are Becoming More PopularB. Robots Contribute aLotto the WorldC. Robots Are in Great Demand NowD. Security Robots Could Help Cut CrimeBIn the summer of 2016, I gave a talk at a small conference in northernVirginia. I began by admitting that I’d never had a social-media account; I then outlined arguments for why other peopleshould consider removing social media from their lives. The event organizers uploaded the video of my talk to YouTube. Then it was shared repeatedly on Facebook and Instagram and, eventually, viewed more than five million times. I was both pleased and annoyed by the fact that my anti-social-media talk had found such a large audience on social media.I think of this event as typical of the love-hate relationships many of us have with Facebook, Instagram, and other social-media platforms. On the one hand, we’ve grown cautious about the so-called attention economy, which, in the name of corporate(公司的) profits, destroys social life gradually and offends privacy. But we also benefit from social media and hesitate to break away from it completely. Not long ago, Imet a partner at a large law firm in Washington, D.C., who told me that she keeps Instagram on her phone because she misses her kids when she travels; looking through pictures of them makes her feel better.In recent months, some of the biggest social-media companies, Facebook and Twitter, in particular, have promised various reforms. In March, Mark Zuckerberg announced a plan to move his platform toward private communication protected by end-to-end encryption(端对端加密); later that month, he put forward the establishment of a third-party group to set standards for acceptable content.All of these approaches assume that the reformation of social media will be a complex, lengthy, and gradual process. But not everyone sees it that way. Alongside these official responses, a loose collective of developers that calls itself the IndieWeb has been creating another alternative. They are developing their own social-media platforms, which they say will preserve what’s good about social media while getting rid of what’s bad. They hope to rebuild social media according to principles that are less corporate and more humane(人道的).4. Why did the author feel annoyed when his video was spread online?A. His video caused many arguments.B. His video was shared without his permission.C. His talk was opposed by a large amount of people.D. His video’s popularity on social media is against his talk.5. Why does the author mention the story of his partner in paragraph 2?A. To prove that social media has some benefits.B. To advise people to break away from social media.C. To tell the negative effects social media may produce.D. To describe people’s complicated relationships with social media.6. What is the purpose of the reform made by some social-media companies?A. To attract more users.B. To improve network environment.C. To make more profits.D. To provide more convenientservice.7. What does the IndieWeb intend to do?A. Develop new social-media platforms.B. Remove social media from people’s lives.C. Improve the existing social-media principles.D. Help social-media companies to make reformation.CSummer heat can be dangerous, and heat leads to tragedy far toooften. According to kidsandcars, org, an average of 37 young children per year die of car heat in the US, when they are accidentally left in a hot vehicle.For Bishop Curry, a fifth grader from Mckinney, Texas, one such incident hit close to home. A six-month-old baby from his neighborhood died after hours in a hot car. After hearing about her death, Curry decided that something needed to be done. Young Curry, who turned 11 this year, has always had a knack for inventing things, and he drew up a sketch (草图) of a device he called “Oasis.”The device would attach to carseats and watch the temperature inside the car. If it reached a certain temperature in the car, and the device sensed a child in the carseat, it would begin to circulate cool air. Curry alsodesigns the device using GPS and Wi-Fi technology, which would alarm the child’s parents and, if there was no response from them, the police.Curry’s father believes that the invention has potential. “The cool thing about Bishop’s thinking is none of thistechnology is new,” he said. “We feel like the way he’s thinking and combining all these technologies will get to production faster.” His father even introduced the device to Toyota, where he works as an engineer. The company was so impressed that they sent Curry and his father to a car safety conference in Michigan.In January, Curry’s father launched a campaign for the invention. They hope to raise money to finalize the patent, build models, and find a manufacturer. Their goal was $20,000, but so many people believed in Oasis’ potential that they have raised more than twice that — over $46,000.Curry’s father remembers the first time he saw his son’s sketch. “I was so proud of him for thinking of a solution,” he said. “We always just complain about things and rarely offer solutions.”8. What inspired Curry to invent Oasis?A. His narrow escape from death after being locked in a car.B. His knowledge of many children’s death because of car heat.C. The death of his neighbor’s baby after being left in a hot car.D. The injury of 37 children in his school in a car accident.9. What would Oasis do if it was hot in a car with a child?A. It would inform the parents or even the police.B. It would pump out the hot air in the car.C. It would sound the alarm attached to the car.D. It would get the window open to save the child.10. What does Curry’s father think is cool about Curry’s invention?A. It used some of the most advanced technology.B. It simply combined technologies that existed.C. It could accelerate production of new technology.D. It is the most advanced among similar products.11. Why did Curry’s father start a campaign to raise money?A. To conduct experiments to test the invention.B. To get other children devoted to inventions.C. To support a charity of medical aid for children.D. To get the patent and bring it to production.DAt the foot of the Tianmu Mountain in Zhejiang, a homestay (民宿) is attracting travelers from far and wide,which has won architectural (建筑学的) medal at the 2021 German iF Design Awards.The owners of the homestay are a couple in their late 30s who decided to return to their hometown three years ago. Li Xiumei used to be in charge of a division at a company in Hangzhou, and her husband was a sales director. It was an ordinary situation where Li’s husband was on business trips a lot and Li worked overtime on weekends. City life sometimes is not easy.In 2018, they quit jobs and went back to Dongtianmu village, which lies in a forest of bamboo. The first time they drove into the village was one late afternoon. The cooking smoke was rising from the foot of the mountain, which gave them a very different feeling form thecity.The homestay was built beside her husband’s old countryside house. The old house is preserved (保留), while a brand-new building was built on its side and the whole site is made up of for courtyards. It has been updated to have a hall, a tea room, a kitchen, a dining room. Japanese cherry trees are planted in the east courtyard. A swimming pool is placed in the west courtyard, with a bar located on one side.Li and her husband love gardening and music, and their new home gives them enough space to continue their interests and relax in the heart of nature. Li wants to share the quiet country life, so she makes her new home a homestay. In 2019, the homestay became an online hit after guests shared their experiences on social media. “The longer I stay here, the more I feel it was the right choice to come back, and this is more meaningful than making money,” Li says.12. How did Li feel about city life?A. Satisfied.B. Tired.C. Attractive.D. Noisy.13. What impressed the couple when first driving to the village?A. The smoke of cooking.B. The forest of bamboo.C. The smell of the village.D. The feeling of loneliness.14. What can we infer about the homestay from paragraph 4?A. It is ancient and broken.B. It can hold many guests.C. It has been rebuilt bythe couple.D. It must have been carefully designed.15. What’s more meaningful than earning money according to Li?A. Continuing their music dream.B. Staying at the old house.C. Living in the countryside.D. Developing the economy of cities.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。

20世纪60年代，广东调查所得，有鹅蛋荔和丁香大荔,重达四五十克。
还有四川合江产的“楠木叶”，四川果树良种图谱》说它重19克左右，《中国果树培学》则说大者重60克，不知哪一本书记载正确。
所谓膜如紫绡，是指壳内的一层通常白色而紧贴壳的内壁的薄膜。
说它“如紫绡”，是把壳内壁的花纹误作膜的花纹了。
明代徐渤有一首《咏荔枝膜》诗，描写吃荔枝时把壳和膜丢落在地上，好似“盈盈荷瓣风前落，片片桃花雨后娇”，是夸张的说法。
荔枝的肉大多数白色半透明，所以说它“莹白如冰雪”。
有的则微带黄色。
从植物学的观点看，它不是果肉，而是种子外面的一层膜发育而成的，特称假种皮。
真正的果肉倒是前面说的连同果壳丢弃的那一层膜。
荔枝肉的细胞壁特别薄，所以入口一般都不留渣滓。
味甜微酸，适宜生食。
有的纯甜。
早熟品种则酸味较强。
荔枝晒干或烘干，肉就成红褐色，完全失去洁白的面貌。
荔枝不耐贮藏,正如白居易说的:“一日而色变,二日而香变,三日而味变,四五日外,色香味尽去矣。
”在21摄氏度的环境里，可贮藏一二星期。
人们一直在设法延长贮藏期，以利于长途运输。
早在1800多年前，即东汉和帝时，唐羌曾谏阻从南方向洛阳贡献生荔枝和龙眼。
唐代杜牧诗云：“长安回望绣成堆，山顶千门次第开。
一骑红尘妃子笑，无人知是荔枝来。
”当时是“昼夜奔腾，有毒虫猛兽之害”（宋蔡襄），“颠坑仆谷相枕藉”，“惊尘溅血流千载”（宋苏轼）。
为了封建统治者个人口腹之好，竟如此劳民伤财！但也足见当时荔枝贮藏与运输的不易。
荔枝的核就是种子，长圆形，表面光滑而色棕褐，少数品种为绿色。
优良的荔枝，种子发育不全，形状很小，有似丁香，也叫焦核。
现在海南岛有无核荔枝，核就更加退化了。

英语部分：Passage1Let us all raise a glass to AlphaGo and the advance ofartificial intelligence.AlphaGo,DeepMind’s Go-playing AI,just defeated the best Go-playing human,Lee Sedol.But as wedrink to its success,we should also begin trying to understandwhat it means for the future.The number of possible moves in a game of Go is so huge that,in order to win against a player like Lee,AlphaGo was designed to adopt a human-like style of gameplay by using a relatively recent development—deep learning.Deep learning uses large data sets,“machine learning”algorithms(计算程序)and deep neural(神经的)networks to teach the AI how to perform a particular set of tasks.Rather than programming complex Go rules and strategies into AlphaGo,DeepMind designers taught AlphaGo to play the game by feeding it data based on typical Go moves.Then, AlphaGo played against itself,tirelessly learning from its own mistakes and improving its gameplay over time.The results speak for themselves.Deep learning represents a shift in the relationship humans have with their technological creations.It results in AI that displays surprising and unpredictable menting after his first loss,Lee described being shocked by an unconventional move he claimed no human would ever have made.Demis Hassabis, one of DeepMind’s founders,echoed this comment,“We’re very pleased that AlphaGo played some quite surprising and beautiful moves.”Unpredictability and surprises are—or can be—a good thing.They can indicate that a system is working well,perhaps better than the humans that came before it.Such is the case with AlphaGo.However,unpredictability also indicates aloss of human control.That Hassabis is surprised at his creation’s behaviour suggestsa lack of control in the design.And though some loss of control might be fine in the context of a game such as Go,it raises urgent questions elsewhere.How much and what kind of control should we give up to AI machines?Howshould we design appropriate human control into AI that requires us to give up someof that very control?Is there some AI that we should just not develop if it means any loss of human control?How much of a say should corporations,governments,experts or citizens have in these matters?These important questions,and many others like them,have emerged in response,but remain unanswered.They require human,not human-like,solutions.So as we drink to the milestone in AI,let’s also drink to the understanding thatthe time to answer deeply human questions about deep learning and AI is now.33.What contributes most to the unconventional move ofAlphaGo in the game?A.The capability of self-improvement.B.The constant input of large data sets.C.The installation of deep neutral networks.D.The knowledge of Go rules and strategies.34.Apotential danger ofAI is________.A.the loss of human control C.the fierce competitionB.the friendly relationship D.the lack of challenge35.How should we deal with the unpredictability ofAI?A.We should stopAI machines from developing even further.B.We should call on the government to solve these problems for us.C.We should rely on ourselves and come up with effective solutions.D.We should invent even more intelligent machines to solve everything.36.What’s the author’s attitude towards this remarkable advance in AI?A.Supportive.B.Optimistic.C.Doubtful.D.Cautious.Passage2Why Doesn’tAnybody CopyApple?Apple’s products are the envy of the world.They have been spectacularly successful and are widely imitated,if not copied.The minute Apple crystallizes aproduct,everyone knows how to compete.This idea that the basis of competition isset by Apple and then the race is on to climb the path of improvement is unquestionable.When Apple releases a product that defines a category or dramatically changes the structure of an industry,it becomes obvious what needs to be built.Butwhat I wonder is why everyone wants to copy Apple’s products but nobody wants to copy being Apple?I can think of two reasons.Firstly,Apple is not worth copying because it’s not successful;secondly,Apple’s success cannot be copied because it is a magical process.There is a great deal of evidence for the first hypothesis.The idea of Apple being successful is not something reflected in its stock price.Being valued lower than the average company in the S&P(标准普尔)500indicates that to whatever degree Apple was successful in the past,it’s not seen by the vast majority of observers as successfulin the future.Why should one bother copying Apple if it results in being punishedwith a low valuation?If one works really hard at innovation and then that innovation becomes commoditized(商品化)very quickly,why should one bother?When innovation practitioners are asked what makes Apple successful,the answers regarding the cause of this success border on the mythical.The climax of this hypothesis is the“chief-sorcerer”theory of success which places one magician,like Steve Jobs,in charge of casting all the right spells(符咒).What about Apple’s own opinion of what makes it tick?Tim Cook refers to agreat team and integration of hardware,software and services as unique Apple advantages.It’s a better explanation.Integration is something that can take a long time,but it is possible with great effort.A few companies are starting to make movesin that direction,but efforts are half-hearted.There is no“move the Earth”panic to become an integrated company from Samsung,Google or Microsoft.My own suspicion is that Apple is more aware of what makes it special than itlets out.However,as Tim points out,it’s not a formula.It’s complex,it’s subtle,butit’s not magic.It’s a process that requires a degree of faith and courage.37.When a new product ofApple comes out,often it____.A.ruins an industry dramaticallyB.starts a revolution of an industryC.puts itself in an unbeatable positionD.is soon overtaken by imitated products38.According to the passage,other companies don’t“copy being Apple”because____.A.Apple is not a successful companyB.they have no access to relevant resourcesC.it’s hard to find a magician like Steve JobsD.being Apple takes more than time and efforts39.We can infer from Para.5that____.A.other companies are dedicated to integrationB.Apple itself is fully aware of its unique advantagesC.Apple will hold the leading position in this industryD.other companies don’t have a great team as Apple does40.What does the author think of Tim Cook’s statement?A.Convincing. C.Unquestionable.B.Disappointing.D.Acceptable.科学部分：41.太平洋正在如何变化（）A、变小B、变大C、不变D、有时变小有时变大42.经线和纬线之间的夹角是（）A、60°B、90°C、45°D、30°43.下列有关潮汐的说法正确的是（）A、地球站在太阳和月球连线上时，会发生小潮B、月球站在太阳和地球连线上时，会发生小潮C、每天每个地方一定会有两次高潮和两次低潮D、太阳、地球和月球成直角时，会发生小潮44.如果地球只有一个苹果那么大，那么大气的厚度相当于（）A、果皮B、果肉C、果核D、果皮上的水汽45.以下哪个不是液体表面张力造成的现象？（）A、船漂在水面上B、树叶上的水滴C、小虫在水面上行走D、针漂在水面上46.以下哪个是玻璃不可能具备的特点？（）A、耐加热B、熔化后可以吹成不同的形状C、比沙子熔点低D、结晶体47.水分在人体内最重要的角色是以下哪一个？（）A、容器B、反应物C、溶剂D、催化剂48.如果你受伤了，以下哪种血液组分会帮助你止血？（）A、红细胞B、白细胞C、血小板D、血浆49.保温瓶的双层玻璃夹层里被抽成真空加以密封。
