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A home science experiment recently took the world by storm. Two teens from Toronto, in Canada, sent a Lego man rising above the Earth and captured their tiny astronaut's trip on film.Mathew Ho and Asad Muhammad, both 17, used a weather balloon to launch their plastic lego model 16 miles above the Earth. This is inside a part of Earth's atmosphere.The two teens were inspired by a similar project performed by students at the Massachusetts Institute of Technology(MIT). The MIT students had launched a weather balloon with a camera into near space and taken many unusual images of the Earth. Mathew and Asad then spend four months figuring out how to launch their own spacecraft into the space.Travelling to space is expensive for NASA, but Mathew and Asad worked hard to keep their costs down. They bought much of their equipment used and even sewed the Lego man's parachute by hand. In total, the project cost only$400."We had a lot of anxiety on launch day because there were high winds when we were going up," Mathew told reporters. They had to pump extra helium(氦)into the balloon so that it would rise quickly and avoid being blown too far off course by the strong winds.The toy astronaut's journey lasted 97 minutes before the balloon broke and he fell back to Earth. Mathew and Asad then spent two weekends looking for their spacecraft. It had landed 76miles away from the launch site.The student scientists are currently finishing up their final year of high school and applying for colleges. They are also looking into more do-it-yourself space projects."I guess the sky is not really the limit anymore," Mathew told reporters. "We never knew we'd get this far. It's been a lesson for us that hard work pays off."（1）By saying "took the world by storm" in the first paragraph, the writer meant the experiment______________.A. destroyed the worldB. flooded the worldC. fascinated the worldD. managed the world（2）Which of the following about the students at the Massachusetts Institute of Technology is right?A.They were examples for Mathew Ho and Asad Muhammad.B.They helped Mathew Ho and Asad Muhammad to achieve dream.C.They launched weather balloon together with Mathew Ho and Asad Muhammad.D.They studied with Mathew Ho and Asad Muhammad in the same school.（3）How did Mathew Ho and Asad Muhammad keep their costs down?A.By sewing the weather balloon themselves.B.By borrowing spacecraft from the MIT students.C.By making their spacecraft by hand.D.By using second-hand equipment.（4）What problems did Mathew Ho and Asad Muhammad have on launch day?A.They ran out of helium.B.The wind was too strong.C.The balloon suddenly broke.D.Their spacecraft was blown away.【答案】（1）C（2）A（3）D（4）B【解析】【分析】这是一篇记叙文。

一、高中英语阅读理解1．阅读理解Last week, Vodafone started a test of the UK's first full 5G service, available for use by businesses in Salford. It is part of its plan to trial the technology in seven UK cities. But what can we expect from the next generation of mobile technology?One thing we will see in the preparation for the test is lots of tricks with the new tech. Earlier this year, operators paid almost £ 1.4 billion for the 5G wavelengths, and to compensate for that cash, they will need to catch the eye of consumers. In September, Vodafone used its bit of the range to display the UK's first hologram (全息) call. The Manchester City captain Steph Houghton appeared as a hologram in Newbury. It isn't all holograms, however: 5G will offer faster internet access, with Ofcom (英国通讯管理局) suggesting that video that takes a minute to download on 4G will be available in just a second.The wider application is to support connected equipment on the "internet of things" -not just the internet-enabled fridge that can reorder your milk for you, but the network that will enable driverless cars and delivery drones (无人机) to communicate with each other.Prof William Webb has warned that the technology could be a case of the emperor's new clothes. Much of the speed increase, he claims, could have been achieved by putting more money in the 4G network, rather than a new technology. Other different voices have suggested that a focus on rolling out wider rural broadband access and addressing current network coverage would be more beneficial to the UK as a whole.Obviously, 5G will also bring a cost to consumers. It requires a handset for both 5G and 4G, and the first 5G-enabled smart phones are expected in the coming year. With the slow pace of network rollout so far, it is likely that consumers will end up upgrading to a new 5 G phone well before 5 G becomes widely available in the next couple of years.（1）Why does Prof William Webb say "the technology could be a case of the emperor's new clothes"?A. He is in favor of the application of the new technology.B. 5G will bring a cost to consumers in their daily life.C. 5G helps people communicate better with each other.D. He prefers more money to be spent on 4G networks.（2）The underlined word "addressing" in the fourth paragraph has the closest meaning to________.A. making a speech toB. trying to solveC. managing to decreaseD. responding to （3）The last paragraph indicates that .A. it'll take several years .to make 5G accessible to the public in the UKB. 5G service shows huge development potential and a broad marketC. customers are eager to use 5G smart phones instead of 4G onesD. it's probable that 5G network rollout is speeding up in Britain（4）What do we know about the text?A. Vodafone is successful in spreading the 5G service.B. Steph Houghton appeared as a hologram by 4G.C. The application of 5G will make life much easier.D. 5G phones are available in rural areas of the UK.【答案】（1）D（2）B（3）A（4）C【解析】【分析】本文是一篇说明文。

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.

2020-2021高考英语压轴题专题复习—阅读理解的综合含答案解析
一、高中英语阅读理解1．阅读理解Every year migratory(迁徙的) bats travel from Mexico to Bracken Cave, where they spend the summer consuming insects that would otherwise hungrily eat common food crops. But the bats have been showing up far earlier than they did two decades ago.In a study, scientists at Rothamsted Research, an agricultural laboratory in England, used radar data from 160 U.S. weather stations to analyze activity in the Texas bat colony from 1995 through 2017. They discovered the creatures were leaving their winter quarters in Mexico earlier and reproducing sooner. They were also astonished to find increasing numbers of bats overwintering(过冬) at Bracken Cave instead of heading back to their cold weather quarters in Mexico. Overwintering is a sign that warmer temperatures change the bats' annual rhythms, Rothamsted biologist Phillip Stepanian says.A separate study of migratory bats in Indiana, published last year, found that temperature variations affected arrival and departure times—likewise hinting at the potential influence of climate change. Joy O'Keefe, a biology professor at Indiana State University and co-author of that study, says early arrival at their summer habitats(栖息地) could expose these bats to cold snaps(寒流), and they could freeze to death.Joy O'Keefe and her colleagues also found that changing bat migration times can also clash with rainfall patterns. Many insects that bats eat breed in seasonal lakes and puddles. If the bats arrive too early to benefit from summer rainfall and the resulting abundance of insects they may struggle to feed their pups(幼崽) or skip reproduction altogether, O'Keefe says. She fears this shift could cause Midwestern bats to decrease toward extinction, which would be bad news for humans. "Declines in bat populations could have severe effects for crop success," she says, adding that bats also "control significant disease vectors, such as mosquitoes."However, scientists are not certain that climate change alone is causing the Bracken Cave bat colony to migrate earlier. They have found a direct link between seasonal temperatures and bird migration, but bats are also influenced by factors such as changes in wind speed and direction. And there are other complications. “Bats are mysterious little animals th at move mostly at night and are difficult to observe and track," Stepanian says. "We have this conceptual picture of what might be happening, but really tying it to the cause is the next step."（1）Scientists at Rothamsted Research found that _________.A. bats prefer colder weatherB. bats delay their reproductionC. warming affects bat migrationD. radar can be used to observe bats（2）Joy O'Keefe discovered that _________.A. bats are used to living in rainfall seasonsB. bats' earlier migration might harm farmingC. insects' reproduction helps to spread diseaseD. insects shortage makes bats reproduce earlier（3）What does the last paragraph want to tell us?A. Wind speed and direction affect bats.B. It is difficult to observe and track bats.C. Climate change makes bats migrate earlier.D. Further research on the cause is necessary.（4）What is the best title for the passage?A. Bats' habitatsB. Endangered batsC. Bats' scheduleD. Bats, our good friends【答案】（1）C（2）B（3）D（4）C【解析】【分析】【点评】本文是一篇说明文，作者先提出蝙蝠迁徙提前的这种现象，然后分析了这种现象可能导致的后果，最后分析了可能导致蝙蝠迁徙提前的原因。

2020-2021高考英语阅读理解提高练习题压轴题训练附答案解析
一、高中英语阅读理解1．阅读理解When he was young, Louis Armstrong was taking what was called “Creole jazz”, which was also called dance music, and combining it with trumpeter (小号手) Buddy Bolden, to create what would eventually become today's jazz.Armstrong accomplished that with almost no formal training. He received little training before he was placed in the New Orleans Colored Waif's Home at the age of 12, after a run-in (小争执) with the police. The punishment turned out to be a mixed blessing, for he also had the opportunity to play in a real band.While at the Waif's, Armstrong also got the chance to hear some of the city's finest musicians. Cornetist Freddie Keppard performed in a nearby club. So did trumpeter and bandleader, King Joe Oliver, who took the boy under his wing and taught him how to read music and work on his playing technique.When Oliver left for Chicago, Armstrong chose to stay in New Orleans and work with some of the other top musicians of the day. In Chicago, King Oliver offered him a place in his band in 1922. It became Armstrong's biggest challenge yet — the band had no parts written for trumpet, so he was forced to listen to King Oliver and improvise (即兴创作).Soon, Armstrong's undeniable talent was getting notice. Even classically trained musicians would come to hear the incredible sounds this young man created.Lil Hardin, the bands piano player and the future Mrs. Armstrong, explains that Oliver kept Armstrong in the second trumpet-chair so that Oliver would still be “King”. Hardin convinced him to leave the band.Armstrong moved to New York City in 1924 to join Fletcher Henderson's band and then flew solo. In 1925, Armstrong put together the Hot Five, expanding his popularity even more. Armstrong recorded his first composition, Cornet Chop Suey, one of the most copied jazz solos of all time. This monumental 1928 recording blends (混合) artistry, endurance and showmanship that has rarely, if ever, been matched in Jazz.（1）What does the underlined word “that” refer to in the second paragraph?A. To play dance music.B. To work with Buddy Bolden.C. To create modem jazz music.D. To play a jazz instrument well.（2）Who taught Louis Armstrong how to play music in the early time?A. Buddy Bolden.B. Lil Hardin.C. Cornetist Freddie Keppard.D. King Joe Oliver.（3）Why did Louis Armstrong Leave King Oliver's band?A. Because he wanted to get married in New York.B. Because the man forced him to leave the band.C. Because he got a better opportunity in New York.D. Because his talent could not develop completely.（4）What's the main idea of the passage?A. It asks readers to know more about modern jazz.B. It introduces one of the greatest jazz musicians.C. It introduces the development of jazz.D. It describes the importance of talent in playing jazz.【答案】（1）C（2）D（3）D（4）B【解析】【分析】本文是一篇记叙文，介绍了音乐人Louis Armstrong学习音乐的过程。

一、高中英语阅读理解1．阅读理解Everybody, at some point in their lives, has experienced failure. It could be something as simple as not getting the job you wanted, or getting fewer marks even after hard work. But what makes you is not your failure, but how you get back up after being hit.Once, a young school boy was caught in a fire accident in his school and was assumed that he would not live. His mother was told that he was sure to die, for the terrible fire had destroyed the lower half of his body. Even if he were to survive, he would be lame throughout his life.But the brave boy did not want to die nor did he want to be lame. Much to the amazement of the doctor, he did survive. But unfortunately from his waist down, he had no motor ability. His thin legs just hung there, lifeless. Eventually he left the hospital. But his determination to walk was unshakable. At home, when he was not in bed, he had to stay in a wheelchair. One day, he threw himself from the chair and pulled himself across the grass, dragging his legs behind him. He reached the fence, raised himself up and then began dragging himself along the fence, firmly determined. He did this every day, with faith in himself that he would be able to walk unaided. With his iron determination, he did develop the ability to stand up, then to walk on and off, then to walk by himself and then to run.He began to walk to school, and then run to school, to run for the joy of running. Later in college he was on the track team.In February 1934, in New York City's Madison Square Garden, this young man who was not expected to survive, who would surely never walk, who could never hope to run-this determined young man, Dr. Glenn Cunningham, ran the world's fastest mile.A good example of the power of positive thinking and faith in one's self, Glenn Cunningham continues to be an inspiration for many, and his story, a brilliant evidence to how one can bounce back even when all difficulties are piled against one, to the degree that death seemed the preferable option.（1）The first paragraph is intended to ________.A. present an argumentB. make preparations for statementC. arouse readers' interestD. function as a brief introduction（2）What was the doctor's opinion about Glenn?A.

2．阅读理解In 1953, a mountain climber reported seeing a bar-headed goose soar over the peak of Mount Everest (珠穆朗玛). It was thought impossible. Now researchers who raised 19 of the geese—named for the black stripes on the backs of their heads—have shown the birds really fly so high. The team trained the youngsters to fly in a large wind tunnel wearing backpacks and face masks full of sensors that recorded their heart rate. blood oxygen levels, temperature, and metabolic rate—how many calories they burned per hour. The researchers simulated(模拟)10w-, medium-, and high-altitude conditions by altering the concentration of oxygen supplied to face masks worn by each goose as it flew in the tunnel.Birds already have a better heart and lungs than mammals for sustained physical activity. And researchers knew that bar-headed geese have even larger, thinner lungs that let them breathe more deeply and an even bigger heart to pump more oxygen to muscles than other birds.The wind tunnel experiments showed that when the concentration of oxygen was at its lowest-like the 7% found on top of Mount Everest versus 21% at sea level—the geese's heart rate and frequency of wing beats remained the same even as their metabolic rate dropped. Somehow, the birds managed to cool down their blood-the measured blood temperature dropped so it couldtake in more oxygen, the researchers report today in eLife. This cooling likely helps compensate for the very thin air, the team says.Although well trained, the birds were only willing to stay in the air a few minutes-or less when wearing their backpacks and flying at 6ihigh" altitudes. So it's not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest. But those few minutes showed these geese really could fly over the top of Mount Everest.（1）Why did the researchers raise 19 bar-headed geese and train them?A. To test the flying height and speed of them.B. To confirm they could fly over Mount Everest.C. To observe them flying through the wind tunnel.D. To see how many calories they burned per hour.（2）What can we learn from the wind tunnel experiment?A. It was carried out at very high altitude.B. The geese managed to breathe less when their blood decreased.C. The geese could live through the lowest concentration of oxygen.D. It shows the geese could fly at high altitude for long.（3）What still puzzles scientists about the geese?A. Whether they have super hearts and lungs.B. Whether they have muscles pumped more oxygen to.C. Whether they are willing to wear backpacks and face masks.D. Whether they can manage to fly 8 hours to climb over Mount Everest.（4）Where does the text most probably come from?A. A science fiction.B. A climbing guide.C. A travel brochure.D. A science report.【答案】（1）B（2）C（3）D（4）D【解析】【分析】本文是一篇说明文，登山者报告说看到一只长颈鹅翱翔在珠穆朗玛峰的顶峰，为了确认其真实性，研究人员养了18只这种鹅，在大型风洞中训练它们飞行。
