一、高中英语阅读理解1．阅读理解A typical child plays many roles, such as friend, neighbor, son or daughter. Simply reminding children of that fact can lead to better problem-solving and more flexible thinking, according to new research from Duke University.Better problem-solving was just one positive finding of the study, said lead author Sarah Gaither, an assistant professor of psychology and neuroscience at Duke. After thinking about their own various identities, children also showed more flexible thinking about race and other social groupings—a behavior that could be valuable in an increasingly diverse society.In a series of experiments, Gaither and her colleagues looked at 196 children, ages 6 and 7. In an experiment, one group of children was reminded that they had various identities, such as son, daughter, reader or helper. A second group of children was reminded of their multiple physical attributes, such as a mouth, arms and legs. All the children then needed to handle a few tasksChildren who were reminded of their various identities showed stronger problem-solving and creative thinking skills. When shown pictures of a bear staring at honey-filled beehive(蜂窝)high up in a tree, these children had more creative ideas for how the bear might get the honey, such as turning over a bowl so that it became a stool(凳子). In other words, they saw a new use for the bowl. Children who were reminded of their multiple roles also showed more flexible thinking about social groupings. When asked to categorize different photos of faces, they suggested many ways to Spso. They identified smiling faces such as unsmiling ones, and old and young faces. The other children, meanwhile, primarily grouped people's faces by race and gender(性别).The-study suggests ways to promote flexible thinking for the young, which could be especially valuable for teachers." Gaither said."We have this tendency in our society to only think about ourselves in connection with one important group at a time," Gaither said. "When kids think that they have various identities, they show greater abilities."（1）What are all the kids asked to do in the experiments?A.Play different kinds of roles.B.Remind others of their roles.C.Approach several tasks.D.Classify a group of tasks.（2）How does the author mainly clarify the conclusions of the study in paragraph 4?A.By giving examples.B.By using experts' words.C.By listing a few figures.D.By showing cause and effect.（3）What can we learn from Sarah Gaither's words?A.Improving 5 kids flexible thinking ability is important teaching.B.Kids tend to behave selflessly after thinking about their roles.C.Kids' creative thinking ability is easy to discover and develop.D.Teachers are supposed to make the most of the kids' flexibility.（4）What is the best title for the text?A.Kids' Social Abilities Are Consistent with. Their Education.B.Considering Their Various Roles Improves Kids' Abilities.C.Kids Have a Variety of Identities in Their Daily Life.D.Problem-solving Ability Is Necessary for Most Kids.【答案】（1）C（2）A（3）A（4）B【解析】【分析】本文是一篇说明文，介绍了让孩子知道自己有不同的角色可以提高孩子解决问题的能力和创造性思维能力。

一、高中英语阅读理解1．阅读理解Scientists at the University of Oxford have developed new artificial intelligence(AI) software to recognize and follow up the faces of chimpanzees(黑猩猩)in the wild. The new software will allow researchers and wildlife conservationists to significantly cut back on time spent analyzing videos, according to the new paper published in Science Advances.For species(物种)like chimpanzees which have complex social lives and live for many years, getting photos of their behavior taken from short-term field research can only tell us so much," says Dan Schofield, researcher and DPhil student at Oxford University's Private Models Lab, School of Anthropology. "By taking advantage of the power of machine learning to unlock large video files, it makes it possible to measure behavior over the long term."The computer model was trained using over 10 million images(影像):from Kyoto University s Primate Research Institute(PRI) video files of wild chimpanzees in Guinea, West Africa. The new software is the first to continuously track and recognize individual a wide range of poses, performing with high accuracy in difficult conditions such as low lighting and poor image quality. "Access to this large video file has allowed us to use deep neural networks to train models to a degree that was previously not possible," says Arsha Nagrad, co-auther of the study and DPhil student at the Department of Engineer Science, University of Oxford." Additionally, our new software differs from previous primate face recognition software in that it can be applied to videos with limited manual intervention(人工干预), saving hours of time."The technology can be potentially used to monitor species for conservation Although the present application focuses on chimpanzees, the AI software provided will be applied to other species, and help drive the adoption of AI systems to solve(解决)a range of problems in the wildlife sciences.（1）What is the purpose of developing the new soft?A.To save wildlife researchers' time spent in the labs.B.To keep track of wildlife conservationists' behaviors.C.To protect chimpanzees and help them to live longer.D.To recognize and track the faces of wild chimpanzees.（2）What does the underlined word "it" in paragraph 2 refer to?A.Getting photos.B.Analyzing videos.C.A powerful machineD.The new AI software.（3）What does paragraph 4 mainly talk about?A.The working principle of the new software.B.Some limitations of using the new software.C.The unique advantages of the new software.D.Controversial attitudes to the new software.（4）What can be known from the last paragraph?A.Technology advance is the final goal of scienceB.The new software won't just be applied to chimpanzees.C.AI systems are widely used in the wildlife sciences.D.The application of the new technology isn't easy.【答案】（1）D（2）D（3）C（4）B【解析】【分析】本文是一篇说明文，介绍了一种新的人工智能软件，这种软件可以识别和追踪黑猩猩的面孔,大大节省了研究者和野生动物保护者的时间，而且它还可以应用到其他的物种研究。

Although the amputation caused inconvenience for Gallagher early on, she now sees it as nothing short of inspiration for living her best life.To spread that message. Gallagher has gone to social media, where she shares photos of her travels across the world, but instead of simply using a geo-tag (地理位置标签), she writes her location on her artificial leg before taking a picture.Now she has been taking pictures across the Continent, which show her cycling over the canal in Amsterdam relaxing on a wall overlooking the city of Barcelona, posing with a waffle in Brussels, taking in the beautiful Parthenon temple in Athens and enjoying a river ride in Budapest, all with the well-known locations written on her artificial leg."I get a new leg every two years and I can choose the design on it. One day I had a sudden thought to get a chalk-board," Gallagher said. "My mum and grandmother didn't like the idea, but my friends thought it was great and told me to go for it, so I did."Gallagher said people often stare when she's writing on her leg, but once she shares the photos, she receives only positive feedback (反馈), "My leg hasn't stopped me from doing anything I've wanted to do," she said. "I don't know if it's my determination to prove to myself that I can do it, anyway, I've been able to keep up with people at my age and lead a pretty great life."Gallagher shows us that you should never let anything stand in the way of your dreams. And if life gives you an artificial leg, make art.（1）What message did Gallapher want to spread in her special way?A. She enjoys her travelling across the globe.B.

一、高中英语阅读理解1．阅读理解The negative (负面的) health effects of sleep shortages during the week can't be changed by marathon weekend sleep sessions, according to a new study.Researchers have long known that routine sleep deprivation (缺乏) can cause weight gain and increase other health risks, including diabetes. But there are still some people who hope that shutting off the alarm on Saturday and Sunday will repay the weekly sleep debt and remove any ill effects.The research, published in Current Biology, ruins those hopes. Despite complete freedom to sleep in and nap during a weekend recovery period, participants in a sleep laboratory who were limited to five hours of sleep on weekdays gained nearly three pounds over two weeks and experienced metabolic disruption (代谢紊乱) that would increase their risk for diabetes over the long term. While weekend recovery sleep had some benefits after a single week of inadequate sleep, those gains were wiped out when people returned right to their same sleep schedule the next Monday."If there are benefits of catch-up sleep, they're gone when you go back to your routine. It's very short-lived," said Kenneth Wright, who led the research. "These health effects are long-term. It's kind of like smoking once was — people would smoke and wouldn't see an immediate effect on their health, but people will say now that smoking is not a healthy lifestyle choice. I think sleep is in the early stage of where smoking used to be."Wright said that the study suggests people should prioritize sleep — cutting out the optional "sleep stealers" such as watching television shows or spending time on electronic equipment. Even when people don't have a choice about losing sleep due to child-care responsibilities or job schedules, they should think about prioritizing sleep in the same way they would think about a healthy diet or exercise.（1）What had the researchers already known before doing the new research?A. The actual benefits of weekend recovery sleep.B. Harm to health caused by the lack of routine sleep.C. People's habit of shutting off the alarm during holidays.D. The relationship between body weight and sleep amount.（2）Kenneth Wright mentioned smoking to _________.A. call on smokers to completely abandon smokingB. advise people to go to sleep when they want to smokeC. show people have known the harm brought by smokingD. show people will someday notice the bad effects of sleep deprivation（3）What does the underlined word "prioritize" probably mean?A.Have a low opinion of something.B.Increase the amount of something.C.Cut down something that isn't necessary any more.D.Treat something as being more important than others.（4）What can be the best title for the text?A.Weekend Catch-up Sleep Is a LieB.Bad Sleep Habits Are Harmful to HealthC.A New Study Has an Unexpected DiscoveryD.Advantages and Disadvantages of Catch-up Sleep【答案】（1）B（2）D（3）D（4）A【解析】【分析】本文是一篇说明文，作者通过一项研究与对比举例的方法让大家明白周末马拉松式的“补觉”并不能扭转工作日睡眠不足对健康的负面影响。

一、高中英语阅读理解1．阅读理解Gene technology to benefit peopleAmong all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(寿命) can be prolonged.Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial(皇室) family being a good example, have hereditary(遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it and a healthy child will be born.Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.（1）What does "these two killers" in the second paragraph refer to?A. Gene technology and another treatment of the two diseases.B. The two murderers who killed the cloned baby.C. The two diseases of cancer and heart disease.D. Hereditary diseases and cancer.（2）What's the main idea of the third paragraph?A. How gene technology can be applied in the field of treating hereditary diseases.B. Gene technology can be used to clone human babies.C. Gene technology can help people to give birth of a baby.D. Gene technology can help the English imperial family out.（3）In what way gene technology can help to treat hereditary diseases?A. Using gene technology, people with hereditary diseases can have more living days.B. Using gene technology, scientist finds the wrong gene and corrects it.C. Using gene technology, human babies can be cloned.D. Doctors can cure cancer and heart disease with the help of gene technology.（4）What is the main purpose of writing this passage?A. Expressing the writer's idea that gene technology will benefit peopleB. Telling people the advantages of gene technologyC. Telling the readers that gene technology will not benefit peopleD. Explaining that gene technology will also do harm to the humanity【答案】（1）C（2）A（3）B（4）A【解析】【分析】本文是一篇说明文，介绍了基因技术，详细讲述了基因技术的好处。
2020-2021高考英语压轴题专题复习—阅读理解的综合及答案解析
一、高中英语阅读理解1．阅读理解Empathy (同理心)is one of those strange qualities—something almost everyone wants, but few know how to truly give or receive it. In a world where self-satisfaction is emphasized, it is in short supply but high demand. This is all the more reason to teach the next generation what it means to have empathy for those around them.What Is Empathy?— Many people confuse sympathy and empathy, but they are two distinct values. Empathy is not just the ability to understand someone's feelings; criminals often take advantage of people by appearing to understand their feelings and subsequently gaining their trust. Empathy is more than that. Not only is it the ability to recognize how someone feels, but it also values and respects the feelings of another person. It means treating others with kindness, dignity, and understanding.Kids Need To See Adults Show Empathy—While some children are gifted with naturally kind hearts, in most cases kids need to see empathy modeled by the adults around them. It begins with the way parents relate to their children. Parents who show an interest in the things that matter to their kids and respond to emotions in a positive and caring way are teaching the skill of empathy.Meet Emotional Needs—When children have their emotional needs met, two things happen. They learn how to meet the emotional needs of others and they are anchored in what they are receiving, meaning that they are secure enough to give to others when the need arises but first they need to receive. An empty jug cannot fill a cup.It's a good idea to talk to kids about emotions and how other people experience them. Give their emotions names (for example, jealousy, anger, and love) and teach them that these are normal. Talk to them about how to handle emotions in a positive way and point out situations where other people are experiencing emotions. Teach them about respecting the emotions of others and show them how to act in a situation where a response is required.（1）Why is it that the next generation are taught to have empathy?A. Because people tend to center themselves.B. Because everyone lacks empathy.C. Because empathy is a strange quality.D. Because it's better to give than to receive.（2）Which situation can empathy be used in?A.When a mathematician is calculating the area of a farmland.B.When a teacher is comforting a student about his failure in exams.C.When a criminal is cheating a victim.D.When a dancer is dancing to music.（3）What does the underlined sentence "An empty jug cannot fill a cup" mean?A.An empty jug is too small to hold a cup.B.It's a must to talk to kids about emotions.C.Adults should set an example to kids.D.Kids give empathy with their emotional needs met first.（4）What is the main topic of the passage?A.How to train kids to have empathy.B.How to distinguish sympathy and empathy.C.How to help kids finish empathy-related tasks.D.Whether kids can be trained to be more empathetic.【答案】（1）A（2）B（3）D（4）A【解析】【分析】本文是一篇说明文，在一个强调自我满足的世界里，我们更有理由教导下一代，对周围的人抱有同理心意味着什么。

一、高中英语阅读理解1．（2019•浙江）阅读理解California has lost half its big trees since the 1930s, according to a study to be published Tuesday and climate change seems to be a major factor（因素）.The number of trees larger than two feet across has declined by 50 percent on more than 46, 000 square miles of California forests, the new study finds. No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles. In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts of southern California the decline was nearly 75 percent.Many factors contributed to the decline, said Patrick Mclntyre, an ecologist who was the lead author of the study. Woodcutters targeted big trees. Housing development pushed into the woods. Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources（资源）.But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010, Mclntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development.The loss of big trees was greatest in areas where trees had suffered the greatest water shortage. The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking into account such things as rainfall, air temperature, dampness of soil, and the timing of snowmelt（融雪）.Since the 1930s, Mclntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which reduces the water supply available to trees during the dry season.（1）What is the second paragraph mainly about?A. The seriousness of big-tree loss in California.B. The increasing variety of California big trees.C. The distribution of big trees in California forests.D. The influence of farming on big trees in California.（2）Which of the following is well-intentioned but may be bad for big trees?A. Ecological studies of forests.B. Banning woodcutting.C. Limiting housing development.D. Fire control measures.（3）What is a major cause of the water shortage according to Mclntyre?A. Inadequate snowmelt.B. A longer dry season.C. A warmer climate.D. Dampness of the air.（4）What can be a suitable title for the text?A. California's Forests: Where Have All the Big Trees Gone?B. Cutting of Big Trees to Be Prohibited in California Soon.C. Why Are the Big Trees Important to California Forests?D. Patrick Mclntyre: Grow More Big Trees in California【答案】（1）A（2）D（3）C（4）A【解析】【分析】本文属于议论文，围绕加利福尼亚的大树从20世纪30年代以来大量减少为主题，探讨出现这一现象的原因。
（1）段落大意题。
第二段第一句 The number of trees larger than two feet across has declined by 50 percent on more than 46, 000 square miles of California forests 为主题句，意思是：在4.6万平方英里的加利福尼亚的森林中，直径超过2英尺的树木的数量已经减少了50%。
所以本段主要介绍加州的树木损失的严重情况，故答案为A。
（2）细节理解题。
题干中的 well-intentioned 意为“好意的”。
根据第三段描述：伐木者对大树的砍伐、住房向森林里推进、对野火的控制使得小树与大树竞争资源都是导致大树减少的原因。
控制野火的初衷是保护森林，但是却导致大树得不到足够的资源而死亡。
故答案为D。
（3）细节理解题。
将water shortage 定位在第五段，而Mclntyre 在最后一段，根据 the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air 可知，导致水源紧张的是上升的温度，造成树木将更多的水分散失到空气中。
故答案为C。
（4）主旨大意题。
文章的第一句是本文的主题句，文章围绕加利福尼亚大量的大树死亡展开，对大树数量减少的原因进行研究。
故答案为A。
【点评】本文属于生态环保类文章，文章的首段第一句即为本文的主题句。
阅读是紧扣主旨，快速浏览文章内容。
答题时注意根据问题中的关键词在文章中定位，然后分析关键词所在句子的信息。
2．阅读理解It seems we're always being told to get more sleep. Studies suggest spending less time on sleep can lead to obesity(肥胖) and even cancer. You might even find yourself with a head full of false memories. But rarely does science explore the dark side of sleeping too much. That's because few of us in today's busy world have the luck of exploring that option.In an August 2018 study, published in the Journal of the American Heart Association, researchers researched the sleep patterns of those "fortunate" few and found they may not be so lucky after all. In fact, they found people who get more than eight hours of sleep have greater health risk compared to those who sleep together less than seven hours. What's more, sleep-aholics-those who manage to get 10 hours a night-stand a 30 percent higher chance of dyingcompared to the seven-hour crowd.The wide-ranging global study involved(涉及) more than three million people who self-reported on their sleep habits and came to an eye-opening conclusion: If you tend to sleep a lot, you may want to buy an alarm clock. As with all things in life, sleep is best taken in moderation(适度).You may be thinking: What if I only sleep in on Saturday and Sunday, am I still at risk? The answer is yes, according to a 2019 study published in Current Biology. Researchers discovered that even if a person sleeps more than seven hours on the weekends but still sleeps less than that on weeknights, they are at risk of gaining weight and developing sensitivity to insulin, which controls the level of sugar in blood.For the study, 36 participants were divided into three groups that each had a different sleep schedule: nine hours every night, five hours every night, and five hours from Monday to Friday and sleeping much on weekends. People who get too much sleep tend to feel tired and lack energy. Also, both sleep-deprived(睡眠不足的) groups consume more food and gain weight.（1）Why is the harmful effect of sleeping too much seldom studied?A. Few people have time to sleep too much.B. Lack of sleep causes much more harm.C. It turns out to be a healthy sleep pattern.D. People's health has nothing to do with it.（2）What does the underlined words "those 'fortunate' few" in paragraph 2 refer to? A. Those leading a relaxing life. B. Those getting too much sleep.C. Those with less time to sleep.D. Those with no sleep problems.（3）What can be learned from the 2019 study?A. Sleeping much is particularly beneficial to hungry people.B. Many people sleep more on weekends than on weekdays.C. An alarm clock of high quality is important for good sleep.D. People who sleep much only on weekends also have health risk.（4）What is the main idea of the text?A. It is necessary to save enough time for sleep.B. Too much sleep can result in gaining weight.C. Sleeping too much does harm to people's health.D. People can avoid sleeping much by eating healthily.【答案】（1）A（2）B（3）D（4）C【解析】【分析】本文是一篇说明文，我们似乎总是被告知要多睡觉，但是睡眠过多对身体也是有害的。
