一、高中英语阅读理解1．阅读理解A few hours after my first mission, returning to Earth on the space shuttle Endeavour, I completed all of my medical tests after flight, met with NASA officials, and reunited with my family. Finally, I was alone in my office room in astronaut crew quarters at the Kennedy Space Center, exhausted and ready for bed. And I did what anyone does when they return to their hotel room on a business trip: I turned on the TV. The television news started up: Such and such had happened, people were shocked, blah blah blah. Sports scores. Silly commercials.It didn't take more than a minute before I had to turn it off. It felt like my body was rejecting all this input, just as it would reject an organ donation that had the wrong blood type. All of this noise was just completely foreign to who I was—or, more appropriately, who I had become. A few hours before, I had been orbiting Earth, seeing our planet from space, flying the most amazing machine ever built by human hands, working with a team that was the absolute success of human. And now here in my room watching what was being sold as news, and with my newfound perspective, I just could not stomach it. My worldview was changed forever in a profound (深刻的) way.The biggest change by far and the one for which I will always be most grateful is this big-picture perspective. That will stick with me for the rest of my life.Whenever I feel the pressure of modern life, the stress about work, or worry about the future, I remember my time in the space station. Back to seeing the sun set Or watching our galaxy rise on the horizon. Or seeing a sea of lightning flash a hundred times a second. Or simply back to floating weightlessly.When I'm there in my mind and realize how many billions of these beautiful sunsets there have been and will be in the future, the cares of the world just don't seem that pressing. It goes that, "Do not worry about tomorrow, for tomorrow will worry about itself." Living daily life down here on the planet is so much better with this attitude!（1）Which of the following is closest in meaning to the underlined word stomach in paragraph 2?A. Access.B. Attend.C. Accept.D. Afford.（2）What is the most important change to the writer?A. He has a broader view of the world.B. He doesn't like watching TV any more.C. He will always be most grateful for everything.D. He can fly the most amazing machine by hands.（3）What attitude to life does the writer tend to have?A. caged bird longs for clouds.B. Live in the present moment.C. Let bygones be bygones.D. Time works great changes.【答案】（1）C（2）A（3）B【解析】【分析】本文是一篇夹叙夹议文，讲述了在一次太空之旅后作者对待生活的态度的变化。

一、高中英语阅读理解1．阅读理解If conditions get bad enough, almost any kind of weather can become a storm.Stormy weather can cause people to cancel their plans. It can cause major events to be postponed. And severe stormy weather can be dangerous to people, fortune and anima1.If you weather the storm, or ride out the storm, you survive and move on without harm or injury. For example, 1et's talk about Tornado Alley, the name for part of the central United States. During springtime, this area often has a large number of powerful tornadoes. People who live there are taught to shelter in the safest place they can find and wait for the storm to pass. People who live in Tornado Alley are used to weathering many storms!You can also weather a storm, but it does n't involve actual weather. “To weather the storm” can also mean to make it through a difficult experience or trying times. So, if the stock market(股市)crashes, you might have to weather a financial storm.Often before a big storm, conditions are calm. The calm before the storm can happen anytime. It is the time before something bad happens. For example, at the beginning of a family reunion, the adults were all talking happily. But the older children knew it was just the calm before the storm. They've seen it happen before. The adults talk happily for about an hour. Then they start arguing about events from the past—things that should really stay buried!But after the storm begins and you find yourself in the middle of it, you are in the eye of the storm. In the world of weather, the eye of the storm is the calmest part, in the center of a hurricane, for example. However, in the English language, if you are in the eye of the storm, you are in the most intense part of a conflict. For example, she had no idea that walking into the meeting would put her in the eye of the storm.However, a brainstorm does not exist in the world of weather. To brainstorm means to try to solve a problem by talking with other people. And don't worry. If we have trouble thinking of an idea for the next program, we can always brainstorm with you!（1）What's mainly discussed in the 3rd and 4th paragraphs?A. What the meanings of weathering the storm are.B. How we can weather the storm.C. Weathering a storm doesn't involve actual weather.D. People in Tornado Alley can survive the storm.（2）Why does the author mention a family reunion in the fifth paragraph?A. To stress the importance of weather forecast.B. To develop the awareness of family.C. To explain the meaning of an expression.D. To praise the older children for being clever.（3）What can be inferred from the last paragraph?A. A problem can't be solved if you worry too much.B. A brainstorm often appears in the world of weather.C. Difficulties can be dealt with by teamwork.D. To brainstorm can cause troubles in the program.（4）What's the author's purpose in writing the text?A. To tell us stormy weather can cause destruction.B. To tell us some expressions about storm.C. To tell us a storm can cause conflicts.D. To tell us we should be ready for a storm.【答案】（1）A（2）C（3）C（4）B【解析】【分析】这是一篇说明文。

一、高中英语阅读理解1．阅读理解Have you ever imagined what it would be like to see the world through an animal's eyes? For example, what a chimpanzee sees as it sits at the top of a tree, or a penguin's view as it dives into the sea to catch its dinner?These questions are answered in the nature documentary Animals with Cameras, produced by the BBC. The three-part series was first aired in the UK last month. To explore animal stories "told" by the animals themselves, the documentary's filmmakers worked with scientists to develop cameras that wild animals could wear."Never before have we seen such high-quality footage (连续镜头)directly from the animal's point of view, " BBC Nature executive producer Fred Kaufman told PBS." This miniseries greatly expands our comprehension of animal behavior and this camera technology opens up new possibilities for discovering so much more."Indeed, the groundbreaking technology provides a new viewpoint of the animal kingdom. New cameras with enough battery life to shoot for hours at a time were designed to be comfortable enough for animals to wear, according to the documentary's camera designer Chris Watts.The technical challenges didn't stop there. Some animals were very curious about the equipment, with some even fighting each other for the chance to wear a camera. In the case of chimpanzees, "we had to create dummy (仿造的)cameras, so that every chimpanzee could get one", the miniseries' wildlife cameraman Gordon Buchanan told Live Science.For animals that were comfortable enough to be with human beings, the cameras could be fitted and removed by hand. But for others, the cameras came off automatically using a timed release and were collected afterward. This meant that the cameras needed to be as tough as possible.To avoid disturbing the animals, scientists who were good at dealing with wildlife came to help by putting the cameras on the animals." The last thing we want to do is cause them distress." the documentary's producer Dan Rees told the BBC. "To follow an animal in the first place, there had to be a clear benefit in terms of knowledge about it that might be useful to protecting a species in the future.Their efforts certainly paid off. " Footage that captures (捕捉)these rare and exciting glimpses of animals bidden habits is important to scientists, but documentaries like Animals with Cameras also resonate with (引起共鸣)audiences, connecting them with the beauty - and danger - of wildlife in their natural environments," Live Science noted.（1）According to the text, Animals with Cameras .A.is a documentary made by wildlife expertsB.presents high-quality footage of animals for the first timeC.shows wildlife from the unique viewpoint of animalsD.mainly records the life of chimpanzees and penguins（2）The case of chimpanzees is used to .A.reflect the weakness of the camera technologyB.present how filmmakers put cameras on chimpanzeesC.explain why chimpanzees were attracted by the equipmentD.show how filmmakers dealt with the challenges in shooting（3）To avoid disturbing the animals, filmmakers .A.set up a protected area for them to live inB.invited scientists to help equip them with camerasC.made the cameras look like animals in disguiseD.fitted and removed the cameras by hand（4）The author's attitude toward the documentary can be described as .A.changingB.supportiveC.cautiousD.pessimistic【答案】（1）C（2）D（3）B（4）B【解析】【分析】本文是一篇说明文，介绍了研究人员使用最新的相机技术，让人们从动物的视角看世界。

一、高中英语阅读理解1．阅读理解Shark attacks not only disturb beach activities, but can affect associated tourist industries. Shark nets are a common solution to preventing shark attacks on beaches, but they cause dangers to sea ecosystems.Seeking a cost-effective way to monitor beach safety over large areas, we have developed a system called Shark Spotter. It combines artificial intelligence (AI), computing power, and drone (无人机) technology to identify and warn lifesavers to sharks near swimmers. The project is a cooperation between the University of Technology Sydney and The Ripper Group, which is pioneering the use of drones—called "Westpac Little Ripper Lifesavers"—in the search and rescue movement in Australia.SharkSpotter can detect sharks and other potential threats using real-time aerial imagery. The system analyses video from a camera attached to a drone to monitor beaches for sharks, send warnings, and conduct rescues. Developed with techniques known as "deep learning", the Shark Spotter system receives imagery from the drone camera and attempts to identify all objects in the scene. Once certain objects are detected, they are put into one of 16 categories: shark, whale, dolphin, rays, different types of boats, surfers, and swimmers.If a shark is detected, Shark Spotter provides both a visual sign on the computer screen and an audible warning to the operator. The operator confirms the warning and sends text messages from the Shark Spotter system to the Surf Life Savers for further action. In an emergency, the drone is equipped with a lifesaving flotation pod (漂浮仓) together with an electronic shark repellent (驱逐装置) that can be dropped into the water in cases where swimmers are in severe trouble, trapped in a rip, or if there are sharks close by.In January 2018, the Westpac Little Ripper Lifesavers was used to rescue two young swimmers caught in a rip at Lennox Head, NSW. The drone flew down the beach some 800 meters from the lifeguard station, and a lifesaving flotation pod was dropped from the drone. The complete rescue operation took 70 seconds.We believe Shark Spotter is a win-win for both marine life and beachgoers. This unique technology combines dynamic video image processing AI and advanced drone technology to creatively deal with the global challenge of ensuring safe beaches, protecting environments, and promoting tourism.（1）A Shark Spotter is ________.A. a solution to monitor sharksB. an equipment to identify lifesaversC. a technology to prevent shark attacksD. a project to pioneer the use of drones（2）When a shark is spotted near a swimmer, the system will ________.A. take timely actionB. analyze the visual dataC. classify the identified objectsD. turn on "deep learning" mode（3）The example in the 5th paragraph shows us that the system is ________.A. efficient in saving livesB. effective in detecting sharksC. smart in driving sharks awayD. practical over the whole sea area（4）What is the author's attitude towards the future of SharkSpotter?A.Doubtful.B.Optimistic.C.Negative.D.Objective.【答案】（1）C（2）A（3）A（4）B【解析】【分析】本文是一篇说明文，介绍了一种旨在防止鲨鱼袭击的技术Shark Spotter 的工作原理以及重要意义。

一、高中英语阅读理解1．阅读理解City trees grow faster and die younger than trees in rural forestry, a new study finds. Over their lifetimes, then, urban trees will likely absorb less CO2 from the air thah forest trees.As we all know, the earth would be freezing or burning hot without CO2. However, CO2is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burning-of fossil(化石)fuels, have been sending extra greenhouse gases into the air. This has led to a rise in average temperatures across the globe.Studies had shown forests readily absorb CO2, but there hadn't been much data on whether city trees grow, die and absorb CO2at the same rate as forest trees do. So some researchers decided to find out.To figure out how quickly trees were growing, researchers tracked their diameters (the width of their trunks) between 2005 and 2014. A tree's diameter increases as it grows, just as a person's waist size increases as they gain weight. About half the weight of a tree is carbon, research has shown. Most of the rest is water. Over the nine years' tracking, the researchers found city trees absorbed four times as much carbon from the air as forest trees. However, they were twice as likely to die. So over the lifetime of each type of tree, forest trees actually absorbed more CO2.City trees grew faster because they had less competition for light from their neighbors. In a forest, trees tend to grow close together, shading their neighbors. Street trees also benefit from higher levels of nitrogen (氮)in rainwater. Nitrogen helps plants grow. Waste gases from gas-burning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground. Some street trees may also have better access to water than trees in the country because the underground water pipes can leak.（1）What can he known about CO2 from paragraph 2?A. It is one of the side effects of greenhouses.B. It greatly accelerates the process of global warming.C. It results from the widespread burning of fossil fuels.D. It prevents the earth from becoming unsuitable to live on.（2）Why did researchers track the diameters of trees?A. To know about their growth rates.B. To find out how much they weigh.C. To check whether they were healthy.D. To assess the carbon amounts in them.（3）What advantage do city trees have over forest trees?A. They are more likely to access growth promoters.B. They can enjoy more water coming from the air.C. They can enjoy more shade from neighbors.D. They are better at competing for light.（4）What will probably be talked about if the passage is continued?A. How urban trees can live longer.B. Why city living makes trees die young.C. How trees respond to dry soil conditions.D. Why faster-growing trees absorb more CO2.【答案】（1）D（2）A（3）A（4）B【解析】【分析】本文是一篇说明文，一项新的研究发现：与长在森林中的树木相比，城市里的树木长得更快，但死得更早。

一、高中英语阅读理解1．阅读理解A famous Anglican Church stands in a quiet corner of Dunedin in New Zealand's South Island. Built in 1865, it is the city's oldest church still in use. Countless couples have gathered here to marry. It's where morning tears are shared, friendships formed and comfort given during times of loss.As with many churches, its walls are graced with a collection of beautiful stained-glass windows. Known as the "John Allen window", one window portrays the short life of a local man, John Allen, who died in 1915 in the Gallipoli campaign in Turkey.John was the son of Sir James Allen, who as Minister of Defense, helped plan and administer New Zealand's World War I strategy, which saw 100,000 troops sent to fight. With the war over and his son dead, Sir James chose to install a window in the church, with which the Allen family had strong ties.Divided into two parts, one depicts (描绘) St. George, the patron saint (守护神) of soldiers, while the other has an angel of peace, along with the words at the bottom, "John Hugh All Gallipoli, 6th June, 1915". Two trees with local birds on the branches can be seen and a kiwi walks at the bottom- reminders that John was a lover of birds."There are many war memorials in the church," says the church. "However the 'John Allen window' stands out; it touches people because of the beautiful design, the New Zealand birds and because John's story, of a life so full of promise ending tragically in the war, reflects the lives and stories of so many others involved in World War I."（1）What does the word "portrays" in paragraph 2 most probably mean?A. Starts.B. Changes.C. Treasures.D. Represents.（2）Sir James Allen built the "John Allen window" to ______________.A.celebrate the end of World War IB.honor the troops in the Gallipoli campaignC.remember his son's sacrifice to the countryD.show the family's close ties with the church（3）What might be the main theme of the pictures on the window?A.Freedom and equality.B.Peace and war.C.Human and nature.D.Marriage and family.（4）What might be the best title for the text?A.A Brave SoldierB.Window on a LifeC.Cruelty of the WarD.A Grand Church【答案】（1）D（2）C（3）B（4）B【解析】【分析】本文是一篇说明文，介绍了一所教堂中一个被称为"约翰·艾伦之窗"的窗户，上面描绘了一位当地人约翰·艾伦的短暂生命。

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.

一、高中英语阅读理解1．阅读理解Suppose you become a leader in an organization. It's very likely that you'll want to have volunteers to help with the organization's activities. To do so, it should help to understand why people undertake volunteer work and what keeps their interest in the work.Let's begin with the question of why people volunteer. Researchers have identified several factors that motivate people to get involved. For example, people volunteer to express personal values related to unselfishness, to expand their range of experiences, and to strengthen social relationships. If volunteer positions do not meet these needs, people may not wish to participate. To select volunteers, you may need to understand the motivations of the people you wish to attract.People also volunteer because they are required to do so. To increase levels of community service, some schools have launched compulsory volunteer programs. Unfortunately, these programs can shift people's wish of participation from an internal factor (e.g. "I volunteer because it's important to me") to an external factor (e.g. "I volunteer because I'm required to do so"). When that happens, people become less likely to volunteer in the future. People must be sensitive to this possibility when they make volunteer activities a must.Once people begin to volunteer, what leads them to remain in their positions over time? To answer this question, researchers have conducted follow-up studies in which they track volunteers over time. For instance, one study followed 238 volunteers in Florida over a year. One of the most important factors that influenced their satisfaction as volunteers was the amount of suffering they experienced in their volunteer positions. Although this result may not surprise you, it leads to important practical advice. The researchers note that attention should be given to "training methods that would prepare volunteers for troublesome situations or provide them with strategies for coping with the problem they do experience".Another study of 302 volunteers at hospitals in Chicago focused on individual differences in the degree to which people view "volunteer" as an important social role. It was assumed that those people for whom the role of volunteer was most part of their personal identity would also be most likely to continue volunteer work. Participants indicated the degree to which the social role mattered by responding to statements such as "Volunteering in Hospital is an important part of who I am." Consistent with the researchers' expectations, they found a positive correlation(正相关) between the strength of role identity and the length of time people continued to volunteer. These results, once again, lead to concrete advice: "Once an individual begins volunteering, continued efforts might focus on developing a volunteer role identity....Items like T-shirts that allow volunteers to be recognized publicly for their contributions can help strengthen role identity".（1）People volunteer mainly out of __________.A. academic requirementsB. social expectationsC. financial rewardsD. internal needs（2）What can we learn from the Florida study?A.Follow-up studies should last for one year.B.Volunteers should get mentally prepared.C.Strategy training is a must in research.D.Volunteers are provided with concrete advice.（3）What is most likely to motivate volunteers to continue their work?A.Individual differences in role identity.B.Publicly identifiable volunteer T-shirts.C.Role identity as a volunteer.D.Practical advice from researchers.（4）What is the best title of the passage?A.How to Get People to VolunteerB.How to Study Volunteer BehaviorsC.How to Keep Volunteers' InterestD.How to Organize Volunteer Activities【答案】（1）D（2）B（3）C（4）A【解析】【分析】本文是一篇说明文，介绍了怎样让人们去做志愿者的一些方法。

一、高中英语阅读理解1．阅读理解Plastic sludge(污泥)and garbage is a disaster for the world's oceans. A film crew traveled the globe to document the rubbish. And Julie Andersen of the Plastic Oceans Foundation says what we see is just the tip of the problem. “Half o f the waste actually sinks to the bottom, and that remains on the surface actually breaks down. ”The filmmakers found rubbish in ocean gyres, the circulating currents that trap large concentrations of pollution in the Atlantic, Indian, and Pacifc Oceans, home of what some have plastic. What we found was a plastic smog that spread throughout all the water. And in some parts of the oceans, scientists have found more plastic than plant. ”The pieces of the plastic garbage infect the food chain, sometimes visibly, and more so at the microscopic level, where the plastic particles interact with other pollutants. “There are heavy metals, medicines, industrial waste in the sea, while it acts like magnets(磁铁). These poisonous substances absorb on the plastic, and then when seafood absorbs the plastics, those poisonous substances enter the fatty tissues. ”To be consumed by other sea life and by people at last. China, Indonesia, the Philippines, Thailand and Vietnam are the worst plastic polluters.

一、高中英语阅读理解1．阅读理解At the age of seven, while his friends were spending pocket money on things like candy and toys, Jose Adolfo was busy saving money for more essential purchases. To try to get his peers to do the same, the youngster from Arequipa, Peru came up with the innovative idea of an eco-bank, which allows kids of all ages to gain economic independence—while also helping the environment.Established in 2012, the Bartselana Student Bank is the world's first bank for kids. To open an account, kids have to bring in at least 5 kilograms of solid waste (paper or plastic) and establish a savings goal. Once accepted, all bank "partners" are required to deposit(存储) at least one additional kilogram of recyclables on a monthly basis and meet other requirements, such as attending financial education and environmental management workshops.The waste collected is sold to local recycling companies, who, thanks to Jose, pay a higher-than-market rate for everything brought in by Bartselana Student Bank members. The funds received are placed in the individual's account until his/her savings goal is reached. The account holder can then withdraw his/her money, or choose to leave it and continue to grow for a bigger target. "At the beginning, my teachers thought I was crazy," Jose recalls. "They did not understand that we are not the future of the country but its present. Luckily. I had the support of the school principal."By 2013, the bank had over 200 members who brought in one ton of recyclable waste. Today, the eco-bank, which now has the support of several local institutions, has ten educational centers. They are designed to teach the over 3,000 members both finance and environmental management. On December 6, 2018, in response to the growing demand, Bartselana Student Bank began accepting applications from kids all across Peru.As the teenager says, "Together we can change the world. We just need an opportunity."（1）What is the purpose of the eco-bank?A. To involve kids in the management of the local recycling companies.B. To help kids get pocket money to spend on things like candy and toys.C. To show kids how important it is to learn environmental management.D. To get kids to help the environment and be economically independent.（2）What duty does an eco-bank member have to perform?A. Attending financial education workshops.B. Bringing in 5 kilos of waste.C. Saving one kilo of solid waste weekly.D. Establishing a savings goal.（3）What does the underlined part in Paragraph 4 mean?A. Kids are more responsible when growing up.B. The future of the country relies mainly on kids.C. Kids can contribute to the society though young.D. The present is a vital period for kid development.（4）Which of the following words can best describe Jose?A. Generous.B. Crazy.C. Flexible.D.

一、高中英语阅读理解1．阅读理解Your teenage best friend could be good for your long-term mental health, according to a new study published in the journal Child Development According to the findings, teenagers aged 15 to 16 who had a close friendship rather than a larger group of friends they were less close to had a greater sense of self-worth by the time they were 25 years old. Those people with a very close best friend were also less likely to experience depression and social anxiety, the study found. "Close friendship strength in mid-adolescence predicted relative increases in self-worth and decreases in anxiety and depressive symptoms by early adulthood, "the authors, led by Rachel K, Narr, a postdoctoral student focused on clinical psychology at the University of Virginia, wrote.A past research has suggested that adolescent friendships are important. Friendships during the teenage years predict academic success and improved mental health. But the new research further explores the type of friendships teenagers have. "My hunch(预感)was that close friendships compared to broader friendship groups and popularity may not function the same way," Narr told Quartz. "Being successful in one is not the same as being successful in the other." Many study participants did not continue to have a close relationship with their high-school best friend, leading the researchers to wonder what exactly was responsible for the mental health benefits. They suspected that the skills and ability to build such a friendship may be more important than the friendship itself.And as the researchers point out, those skills are not necessarily brought to bear in the world of social media. "As technology makes it increasingly easy to build a social network of shallow friends, focusing time and attention on developing close connections with a few individuals should be a priority," study co-author Joseph Allen said in a statement.（1）What is the benefit of having a close teenage friendship?A. Excellent performance in high school.B. A larger group of friends.C. Mental health by early adulthood.D. A large social network in the future.（2）What can we learn about the past research?A. It attached great significance to adolescent friendships.B. It was totally different from the new research.C. It helped improve teenagers' mental health.D. It compared broader friendship groups with popularity.（3）What did the researchers think might lead to the mental health benefits?A. Not continuing to have a close relationship.B. Having a best friend in high school.C. Understanding the world of social media.D. Knowing how to build a close friendship （4）What did the researcher Joseph suggest?A. Learning to use social media.B. Broadening your social circle.C. Improving the skills of making friends.D. Concentrating on high-quality relationship.【答案】（1）C（2）A（3）D（4）D【解析】【分析】本文是一篇说明文，研究发现，那些有非常亲密的好朋友的人也不太可能经历抑郁和社交焦虑。

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。

一、高中英语阅读理解1．阅读理解It was the beginning of 2011. I had just finished filming the first season of Game of Thrones(《权利的游戏》). With almost no professional experience, I had been given the role of Daenerys Targaryen. The show was so successful that young girls would dress themselves up as Daenerys for Halloween.And yet, terrified of the attention, terrified of trying to make good on the faith that the creators had put in me, I worked much harder.On the morning of February 11, 2011, I was getting dressed in a gym when I started to feel a bad headache. I was so exhausted that I could barely put on my sneakers. I tried to ignore the pain, but I couldn't. I reached the toilet and sank to my knees. A woman came to help me. Then everything became unclear. I only remember the sound of an ambulance.That operation lasted three hours. When I woke, the pain was unbearable. After four days, they moved me out of the I.C.U. (重症监护室). But one day when a nurse asked me, as part of a series of cognitive (认知的) exercises, " What's your name?", I couldn't remember my name and I felt terrified: I am an actor; I need to remember my lines. Now, I couldn't recall my name.The phenomenon is called aphasia. Then I was sent back to the I.C.U. and, after about a week, I was able to speak and know my name. And I was also aware that there were people in the beds around me who didn't make it out of the I.C.U. I was continually reminded of just how fortunate I was.I rarely gave a thought to my health. Nearly all I thought about was acting. I thought of myself as healthy. Once in a while, I would get dizzy. When I was fourteen, I had a migraine (偏头痛) that kept me in bed for a couple of days. But it all seemed manageable — part of the stress of being an actor. Now I think I might have been experiencing warning signs of what was to come.Anyway, there is something pleasant about coming to the end of Thrones. And I'm so happy to be here to see the beginning of whatever comes next.（1）The author felt terrified after acting in the first season of Game of Thrones because _____.①she felt nervous about the public attention.②she had been criticized for her lack of experience.③she was experiencing some warning signs of a serious illness.④she wasn't sure if she had perform ed well in Season 1.A. ①④B. ②③C. ①②D. ③④（2）When did the author lose consciousness?A.

2020-2021高考英语阅读理解培优练习(含答案)附答案

一、高中英语阅读理解1．阅读理解Garbage sorting has become a hot issue around China, especially after Shanghai began carrying out a regulation on July 1.Beijing, as a forerunner in environmental protection, has thus been expected to follow suit. The capital of the country has long been campaigning for sorting and recycling household waste, as part of its environmental drive for sustainable growth, local media reported.The current regulation gives garbage sorting responsibilities to government departments, property management groups and other organizations. It also gives rules for companies, outlining how they're responsible for waste collection, transportation and treatment. Only individuals are not subject to responsibilities.The long-awaited revision will soon change the situation, "Taking out the trash without sorting it properly will be illegal," said Sun Xinjun, director of the Beijing Commission of Urban Management. In Shanghai, violators are now fined up to 200 yuan ($30)for trash-sorting violations. The maximum fine in Beijing will not be less than that, he said.The Beijing city government first set out to promote garbage sorting in 2009. Authorities have since called on citizens to sort their household waste into four types-recyclable waste, kitchen trash, dangerous waste and others-and leave it in a corresponding dustbin or trash can. Blue-colored dustbins signify items within are recyclable, green represents kitchen trash, red corresponds to dangerous materials and grey to other waste.To promote the awareness of garbage sorting and expand the base of participants, authorities have employed workers to help residents on the spot. With intelligent devices, those who throw in recyclable waste at given sites will be rewarded with bonus points, which can be used to buy daily goods. At some communities, there are no color-coded dustbins. Instead, a scheduled garbage collection service is offered to help improve the environment. In other communities, workers offer a door-to-door service to collect recyclables or kitchen waste.Beijing Environmental Sanitation Engineering Group has been promoting new garbage sorting facilities such as recycling cabinets and smart kitchen waste trash cans since 2016, Xinhua News Agency reported. Nearly 26,000 metric tons of household waste is generated across Beijing on a daily basis and 29 terminal garbage disposal facilities are working at full capacity. Nearly 9.3 million tons of household waste was processed in the city last year.（1）According to the passage, which dustbins should some used coke cans be thrown into?A. Grey-colored dustbins.B. Red-colored dustbins.C. Green-colored dustbins.D. Blue-colored dustbins.（2）We can learn from the passage that ________.A. new technology has been applied to help deal with garbageB. Beijing carried out a more severe rule on garbage sorting than ShanghaiC. the change of the current regulation has aroused objection among citizensD. the amount of household waste in Beijing is far from something disturbing（3）What is the best title for the text?A.How to Sort Garbage in ChinaB.The Current Regulation in BeijingC.Garbage Collection in BeijingD.Waste Recycling Project Counts（4）The passage can be sorted as ________.A.a book reviewB.a travel brochureC.an environment reportD.a geography essay【答案】（1）D（2）A（3）C（4）C【解析】【分析】本文是一篇说明文，介绍了垃圾分类在北京的实施情况。

（1）考查词义猜测。

根据第二段中的“It didn't take more than a minute before I had to turn it off.”以及画线词后的“My worldview was changed forever in a profound (深刻的) way.”可知，我的世界观以一种深刻的方式永远改变了，因此此处是说以我现在的视角，看这种新闻是我无法忍受的，所以不到一分钟我就关掉了电视，由此可知画线词词义为“接受、忍受”，故选C。

（2）考查细节理解。

根据第三段中的“The biggest change by far and the one for which I will always be most grateful is this big-picture perspective.”可知，作者最重要的改变是他对世界有更广阔的看法，故选A。

（3）考查推理判断。

根据最后一段中的“It goes that, ‘Do not worry about tomorrow,for tomorrow will worry about itself.’ Living daily life down here on the planet is so much better with this attitude!”可知，它说，“不要为将来担心，生活在这个星球上的日常生活是如此的好，这句话表明了作者对待生活的态度是不要担心将来，活在当下，故选B。

【点评】本题考点涉及细节理解，词义猜测和推理判断三个题型的考查，是一篇人生感悟类阅读，考生需要准确捕捉细节信息，并根据上下文的逻辑关系，进行分析，推理，从而选出正确答案。

2．阅读理解A recent study finds that the dirt on the ground is likely to worsen climate change. Researchers have shown that warmer temperatures are heating the soil, which is causing microbes (微生物) to become more active and release more of the soil's carbon into the atmosphere. These soil changes can potentially contribute to even higher temperatures.Scientists studied device readings, soil measurements, plant growth details and satellite observations from around the world. Their work is the most complete study on the subject.They found a sharp increase in carbon released into the atmosphere by bacteria and fungi (真菌) in soil from 1990 to 2014. Researchers explain that the carbon comes from the dead plants and leaves the microbes eat. As temperatures rise, the microbes eat more. And the more they eat, the more carbon can be made into carbon dioxide and released into the atmosphere.This uncontrolled cycle speeds up and intensifies climate change. Overall, soil releases about nine times more carbon than human activities. But that is part of a natural cycle: the amount of carbon released into the air is about equal to the carbon oceans and plants take in.However, carbon released from fossil fuel causes an imbalance. Burning coal, oil and natural gas puts more carbon into the atmosphere than nature can take in. The additional carbon heats the air and soil. And as the air and soil get hotter, the earth will release more carbon than it has been holding.If something isn't done, we are really in trouble. Proper soil conservation can help keep more carbon in soil. Conservation methods include avoiding turning the soil, covering off-season crops and leaving crop deposits on the ground.（1）Which word can best describe the scientists' research data?A.Rich.B.Rare.C.Limited.D.Difficult.（2）What does the underlined word "intensifies" in Paragraph 4 mean?A.Causes.B.Demands.C.Strengthens.D.Shows.（3）What mainly causes the soil's temperature to rise?A.Active bacteria.B.Human activities.C.The overuses of soil.D.The wastes of fossil fuels.（4）What can be a suitable title for the passage?A.Warmer soil and more carbon.B.The soil and the environment.C.The microbes and the temperatures.D.Hotter air and warmer environment.【答案】（1）A（2）C（3）B（4）A【解析】【分析】本文是一篇说明文，介绍了人类燃烧燃料造成的土壤变化可能导致地球更高的温度。
