说明文——2024届高考英语高考阅读理解文体分类练学校：___________姓名：___________班级：___________考号：___________一、阅读理解Medical artificial intelligence (AI) can perform with expert-level accuracy and deliver cost- effective care. IBM's Watson diagnoses (诊断) heart disease better than cardiologists (心脏病专家) do. Chatbots give better medical advice to patients in place of nurses. Some forecast that medical AI will enter 90% of hospitals and replace as much as 80% of what doctors currently do. Yet, as our recent research suggests, patients show a strong resistance to medical AI.The reason, we found, is not the belief that AI provides lower care. Nor is it that patients think that AI is more costly or less informative. Rather, resistance to medical AI seems to come from a belief that AI does not take into account one's specific circumstances. People view themselves as unique. By contrast, they think medical care delivered by AI providers is suited to treat an average patient but unsuitable to account for the unique circumstances that apply to an individual. No wonder that medical AI providers are given a cold welcome.There are a number of steps that care providers can take to overcome patients' resistance to medical AI. For example, if an AI provider is capable of tailoring its recommendation for whether to have a surgery to each patient's unique characteristics and medical history, patients would be likely to follow the treatment recommendations of the AI provider. In addition, health care providers could also deliver individualized health care by explaining how the algorithms (算法) work and sharing patients' reviews with the media. Having a physician confirm the recommendation of an AI provider should make people more willing to accept AI-based care. People are comfortable using medical AI if a physician remains in charge of the ultimate decision.AI-based health care technologies are being developed and employed at an impressivethem will require that we first overcome patients' doubt of having an algorithm, rather than a person making decisions about their care.1．What made people resist the medical AI?A. A sufferer's temper ignored by medical AI.B. People's lasting trust in a human doctor's ability.C. The concern about its personalization in treatment.D. The accuracy of the information from medical AI.2．What can be a solution to patients' resistance according to the author?A. Treating sufferers as average patients.B. Providing a more specific treatment.C. Getting the algorithms prioritized in time.D. Keeping away from the influence of a physician.3．Which word can replace the underlined word "harnessing" in the last paragraph?A. Weakening.B. Storing.C. Destroying.D. Using.4．What is the suitable title for the text?A. Advantages of Medical AIB. Potential Application of AIC. How AI Replaces Nurses in HealthcareD. The Challenge That Medical AI FacesWith nearly a quarter of global greenhouse gas coming from all types of transportation, can we keep ourselves off gas-powered vehicles to avoid the worst effects? As more governments push for urgent action on climate change, quite a few companies are betting their future—that millions of consumers are finally ready for electric-powered vehicles. Modern battery-powered cars are selling fast and zero-emission(排放) planes are coming. These changes, both leading to a more sustainable future, are reinventing how we get from here to there.Cars and trucks have undergone their greatest improvement since the automobile's existence more than a century ago. Almost overnight, the era of the electric car has arrived. Electricity has the advantage that it works without smell and with less noise. Global annual sales of electric vehicles are expected to soar from just over 3 million today to 14 million by2025. Just a month after Ford unveiled an electric version of the popular F-150, customers had reserved more than 100,000 of them. The price is about $10,000 above the gas-powered one, but Ford says the electric model will cost much less to maintain. Everything creating a green revolution on the ground is of limited help in the sky for the time being.High-storage batteries are useless at present when it comes to the technological challenge of launching a few hundred people into the sky and carrying them thousands of miles. No battery yet invented can power, say, a Boeing 747 from New York to London. Promising improvements, however, do add up. Developments with zero-emission, battery-powered electric engines are already happening in commercial flights, involving trips of limited duration and distance. Airlines specializing in short journeys with small planes will lead theway to electric flights.Our planet's health depends on zeroing out carbon dioxide emissions by 2050, and yet, by the timetable needed to address the climate challenge, the shift away from gas-powered vehicles remains far too slow. Nevertheless, the train has left the station. Someday, electric-powered transportation will be as common5．Why are many companies switching to electric-powered vehicles?A.To reinvent the way we travel.B.To cut the costs of car production.C.To improve the quality of products.D.To pursue sustainable development.6．What do we know about the electric car?A.It came into use a century ago.B.It enjoys increasing popularity.C.It sells better than the traditional one.D.It costs less than the gas-powered one. 7．What does the author intend to do in Paragraph 3?A.To show the disadvantages of battery power.B.To emphasize the significance of short flights.C.To state the developments of commercial flights.D.To stress the future prospects of electric planes.8．What does the author mean by saying "the train has left the station"?A.Train transportation has improved.B.Green transportation is on its way.C.The electric train is running regularly.D.The gas-powered train has become the past.Technology has revolutionized (使革命化) the way we work in many ways. One of the most significant changes has been the shift towards remote and flexible work. With the rise of internet and cloud-based software, workers are no longer tied to a physical office and can work from anywhere with an internet connection. This has allowed for greater flexibility and work-life balance, as well as reduced commuting (通勤) time and costs.Another major change is the increasing use of automation and artificial intelligence in the workplace. This has the potential to increase efficiency and productivity, as well as reduce the need for certain types of work. However, it also raises concerns about job displacement and the need for workers to adapt to new technologies.Finally, technology has greatly expanded the types of jobs available. With the rise of the gig (临时工) economy and freelance (自由职业者) work, workers can now find opportunities in areas such as graphic design (平面设计), copywriting (文案撰写), and socialmedia management. This has created opportunities for individuals to work in areas that were previously inaccessible or did not exist.9．What is the shift in the way we work brought about by technology?A. Flexible and remote work.B. Tying people to a physical office.C. Increased commuting and travel.D. Higher costs and lower productivity. 10．What is the impact of internet and cloud-based software on the way we work?A. It has reduced work-life balance.B. It has increased commuting time and costs.C. It has allowed for greater flexibility and work-life balance.D. It has caused job displacement.11．What are the potential benefits of automation and AI in the workplace?A. Increased job displacement.B. Reduced efficiency and productivity.C. Increased efficiency and productivity.D. Increased commuting and travel.12．What has technology allowed for in terms of job availability?A. Technology has decreased the number of available jobs.B. Technology has created opportunities for individuals to work in areas that were previously inaccessible or did not exist.C. Technology has only impacted traditional office jobs.D. Technology has increased commuting time and costs.Penguins are survivors. Modern species of the adorable birds resist freezing temperatures or dive deep in swift currents. In fact, penguins have been doing their adorable thing for millions of years. Prehistoric penguin species date back to the days of the dinosaurs. A team of researchers in New Zealand have discovered one more member of the ancient family, a tiny and distinctly precious species newly known as Eudyptula wilsonae. Its name, which comes from a New Zealand respected seabird researcher Kerry-Jayne Wilson MNZM, means Wilson's little penguin. Explaining in their recent paper, the researchers detail how the examination of small fossilized skulls(颅骨) led to the classification of this cute creature who lived 50 million years ago.Two fossils were discovered on New Zealand's North Island. Only the skulls are still in existence, and they are slightly narrower than those of modern little penguins which currently frolic(嬉戏) along the island's coasts. From the one young and one adult skull, the researchers determined it was a new species. They likely stood just about a foot tall and weighed2 pounds, much like the modern penguins. In fact, the new species may bea late Pliocene ancestor of the modern birds."This is important when thinking about the origins of these penguins, the evolution of the seabird diversity of New Zealand and the dynamic environment in which they live," co-author Daniel Thomas said in a statement. "For one thing, the climate has changed a lot over this time, and this lineage has been robust(强健的) to those changes." In fact, recent warming has resulted in new challenges for modern little penguins-many starved to death in 2022 as fish moved to cooler waters beyond the diving abilities of the penguins.Ancient penguins' ability to survive when temperatures were warmer in their own time might have modern applications. As cute as these fossilized small penguins are, the modern variety needs humans to look beyond their sweet nature to recognize the complexity of their survival.13．What is Eudyptula wilsonae's name related to?A. A site.B. A shape.C. A person.D. Penguin's appearance.14．What is the feature of the new species?A. They look like modern birds.B.They enjoyed playing by the coasts.C. They share similar heights to modern penguins.D. They are heavier than modern penguins.15．What can be inferred from the third paragraph?A. Thomas attached insufficient importance to the finding.B. The living environment of penguins is worsening.C. The changing climate has little effect on penguins.D. Many fish died due to changes in water temperature.16．Where is the text most likely from?A. An essay from a scientific magazine.B. An introduction to a book.C.A guidebook to biology research.D. A review of penguins' evolution.“Pale Moon rains. Red Moon blows. White Moon neither rains nor snows.” For generations, people have watched the Moon for signs of changes in the weather. The Moon does, in fact, affect the Earth’s climate and weather patterns in different ways.The most obvious effect the Moon has on the Earth can be seen in the ocean tides. A world without tides would have very different weather systems. Tides are one factor that influences the movement of ocean currents, which move warm or cool water around the Earth. Thus, the water temperature changes. Warm ocean currents bring warmer and wetter weather,while cold ocean currents bring colder and drier weather.the amount of Arctic ice. Tidal forces (潮汐力) act to break up ice sheets and change ocean heat flows, changing the amount of ice in the Arctic Ocean. Satellite measurements have shown that the poles are 0.55℃ warmer during a full Moon.The Moon’s influence, sometimes slight and sometimes strong, has had an important impact on life on Earth. Some scientists argue that it is the Moon that made life possible in the first place. The Moon makes the Earth move steadily as it is spinning (自转), helping to give us a steady climate. Without it, the Earth would lose balance. The Moon is our closest friend, without which the Earth would be a very lonely place.17．Why do people watch the Moon according to Paragraph 1?A. To appreciate the moon.B. To record weather patterns.C. To prepare for extreme weather.D. To observe signs of weather changes 18．What impact does the Moon have on the Earth?A. It influences water temperatureB. It makes weather hard to predictC. It turns the earth colder and drier.D. It changes the size of ocean currents. 19．What does the underlined word “fluctuations” mean?A. Change.B. Increase.C. Flow.D. Measurement. 20．What is the best title for the passage?A. Changes of Ocean Heat Flows.B. Patterns of the Earth’s Climate.C. Causes of Changes in Polar Weather.D. Effects of the Moon on Global Weather Osa is an athletic yet stubborn 62-pound German shepherd. The six-year-old dog has mastered the art of sniffing(嗅,闻) out cancer and is key to a research project that has the potential to change oncology(肿瘤学).Osa is part of an ambitious effort launched five years ago at the University of Pennsylvania that aims to develop one of the most powerful scent-detection(气味探测) machines in the world: the canine nose. She is able to distinguish between blood samples (样本) taken from cancer patients and healthy people simply by sniffing them.In fact, Osa is one of five cancer-detection dogs trained by Annemarie DeAngelo and her workmates at the university’s Penn Vet Working Dog Centre. The most important goal is to develop an “electronic sniffer” that can have similar cancer-sniffing superpowers of Osa and her pals. Osa arrived at the Penn Vet Working Dog Centre from a breeder at two months ofage. Ever since, she has taken training. The process is demanding, challenging and repeated until the dog has mastered the most basic task of all. Finally, she has succeeded in sniffing out cancer. To change Osa’s outstanding abilities into an electronic nose, researchers use a similar way to train the machine.An electronic nose prototype(原型,模型) has been built, and it’s successful in sniffing out cancer 90 to 95 percent of the time. That team has also correctly detected different types of cancer, and is building a cancer-detecting device for the National Institutes of Health. One aim is to be able to distinguish between early-stage and late-stage cancer. “It would be amazing to ide ntify people at an early stage and really have an effect on saving lives,” says a researcher. “The dogs have been able to detect that. With that ability, a blood test could be sent to a central lab, or ideally performed in a doctor’s office, making some hi dden cancers a thing of the past. We expect that the cancer-sniffer device will be completed soon. 21．What can we learn about Osa from the first two paragraphs?A. She uses nose to detect the presence of cancer.B. She can change the course of the oncology.C. She was too stubborn to join the research.D. She used to be an athletic German shepherd.22．Which of the following best describes the training according to Paragraph 3?A. Purposeful.B. Boring.C. Strict.D. Endless.23．What can we infer from t he researcher’s words?A. Distinguishing cancers is important in early experiments.B. Blood tests will be more difficult in the future.C. There will be more dogs tested for detecting cancer.D. The hidden cancers may be detected by an electronic nose soon.24．What is the text mainly about?A. The result of a study on dogs’ life.B. The role of dogs in detecting cancers.C. The importance of having a blood test.D. The ways to distinguish cancers.参考答案1．答案：C解析：细节理解题。

专题01 阅读理解(说明文)高频话题01 人与自我—饮食Passage 12022-2023学年下学期·福建福州·高一期末试卷New Year’s Day is meant for food. As the new year arrives around the world, there could be special cakes and breads, for example, long noodles representing long life, field peas representing coins, and pigs representing good luck. The particulars vary, but the general theme is the same: Enjoy food and drink to bring in a year of prosperity. Here are some of the New Year’s food traditions around the world.Hoppin’ John, American SouthA major New Year’s food tradition in the American South, Hoppin’ John is a dish of pork-flavored field peas or black-eyed peas—symbolizing coins—and rice, frequently served with cooked greens—as they’re the color of money and cornbread—the color of gold. The dish is said to bring good luck in the new year.Twelve grapes, SpainThe people of Spain traditionally watch a broadcast from Puerta del Sol in Madrid, where people gather in front of the square’s clock tower to ring in the New Year. Those out in the square and those watching at home take part in an unusual annual tradition: At the stroke of midnight, they eat one grape for every toll of the clock bell. Some even get their grapes ready—peeling and seeding the—to make sure they will be as efficient as possible when mid-night comes.Tamales, MexicoTamales, corn dough filled with meat, cheese and other delicious additions and wrapped in a banana leaf or acorn husk, make appearances at pretty much every special occasion in Mexico. In many families, groups of women gather together to make hundreds of the little packets to hand out to friends, family and neighbors. Soba noodles, JapanIn Japanese households, families eat buckwheat soba noodles, or toshikoshi soba, at mid-night on New Year’s Eve to say goodbye to the year gone by and welcome the year to come.

2022高考英语阅读加餐练之说明文（含答案详解）（A）Mon hunted. Women gathered. But the discovery of a woman buried 9,000 years ago in the Andes Mountains with weapons and hunting tools challenges this widely accepted view. The woman, thought to be between 17and 19 years old when she died, was buried with items that suggested she hunted big-game animals by spear (矛) throwing.The objects accompanying people in death tend to be those that accompanied them in life. Although some scholars have suggested a role for women in ancient hunting, others have dismissed this idea even when hunting tools were uncovered in female burials.To examine whether this woman found at this site was an exception, the researchers examined 429 skeletons at 107 burial sites from around 8,000 to 14,000 years ago. Of those, 27 individuals were buried with hunting tools—11 were female and 15 were male. The sample was sufficient to“justify the conclusion that female participation in early big-game hunting was likely nontrivial,” said lead study author Haas.The findings add to doubts about “man-the-hunter”assumption about early humans since the mid-20th century. That theory assumes that it was men who went out and hunted, bringing home meat to feed women and children, who were responsible for gathering berries, plants and nuts to enrich the dict.But recent research suggests hunting was very much a community-based activity, needing the participation of all able-bodied individuals to drive large animals, the study said. Meanwhile, the spears used at that time had low accuracy, encouraging participation, and using it was as kill learned from childhood. Women may also have been freed from child care demands by “allo-parenting”—raising children was a job shared by many.“Our findings have made me rethink the most basi c organizational structure of ancient hunter-gatherer groups, and human groups more generally,” Haas said.1.The discovery of the buried woman shows__________.A. she was killed by a big-game animalB. she might use hunting tools when aliveC. women were good at throwing spearsD. women were buried alone after death2. The underlined word “nontrivial” in Paragraph 3probably means “__________”.A. limitedB. directC. significantD. passive3. Which of the following lead to women’s involvement in hunting?①allo-parenting ②big-game hunting ③tasks of gathering ④less accurate toolsA.①②③B.②③④C.①③④D.①②④4. Haas probably believes that _________.A. most of our ancestors were buried with hunting toolsB. we should reconsider previous views on human groupsC. division of labor in hunter-gatherer society remains unchangedD. the tomb found in the Andes justifies“man-the-hunter” assumption（B）The idea of low material desire, low consumption andrefusing to work, marry and have children, concluded as a “lying down” lifestyle,recently struck a chord with many young Chinese who are eager to take pause to breathe in this fast-paced and highly-competitive society.Many millennials (千禧一代) and generation Zs complained to the Global Times that burdens, including work stress, family disputes (纷争) and financial strains, have pushed them “against the wall”. They said they hate the“involution (内卷),” joking that they would rather give up some of what they have than get trapped in an endless competition against peers.“Instead of always following the ‘virtues’ of struggle, endure and sacrifice to bear the stresses, they prefer a temporary lying down as catharsis (宣泄) and adjustment,” said a scholar. “Itis no wonder that some young people, under the growing pressures from child-raising to paying the mortgage (按揭) today, would try to live in a simple way and leave the worries behind.”Interestingly, the majority of millennials and Gen Zs reached by the Global Times, who claim to be big fans of the lying down philosophy, acknowledged that they only accept a temporary lying down as a short rest. It is true that with the great improvement of living conditions, some Chinese youth have partially lost the spirit of hardship and are not willing to bear too much hard work. But in fact, lying down is not entirely comfortable. Young people who lie down always feel guilty about their constant loss of morale (士气) far beyond their reach.“Young people on campus have both aspirations and confusion about their future, but most of us have rejected setting ourselves up in chains to waste opportunities and challenges,” a postgraduate student told the Global Times. “It’s no use running away. I have to ‘stand up’ and face the reality sooner or later.”1. What does the underlined phrase in paragraph 1 mean?A. Warned.B. Criticized.C.Touched.D. Amused.2. What might have caused the “lying down” lifestyle among the young?A. Improvements in living conditions.B. Growing pressure from family and social life.C.Increasing material possessions from families.D. Temporary adjustment to failure in competitions.3. What’s the scholar’s attitude toward the “lying down” group?A. Understanding.B.Intolerant.C. Supportive.D. Unclear.4. What can be inferred about the young generation from the text?A. They never really drop their responsibilities.B. They really enjoy the“lying down” lifestyle.C. They find their dreams far beyond their reach.D. They would rather escape than take challenges.（C）Kids spend a lot of time looking at screens. And some parents worry. But a new study argues against the anxiety parents may feel.“Parents are hearing a message that social media, digital technology use is causing very serious and harmful problems like depression, like suicide-related behaviors,”Candice Odgers, professor of psychological science at the University of California said. “But the idea is that if you shut off social media, you could in fact be making a situation worse. Parents are really being sent a message that is not supported by anything scientifically.”Odgers and her colleagues looked at the screen-related behavior of 400 public school students in North Carolina aged 10 to 14. The researchers found that the kids spent between almost five hours to seven hours per day on their devices. That’s a lot of hours but the researchersdidn’t find connection between the amount of time that young people spent online using digital technologies and mental health signs like depression, or anxiety. They found that young people who sent more text messages actually reported better mental health.This was a small association,but it reflects what other people have found: the people who are very connected offline, who use technology in the positive ways to stay connected, often are more connected online as well and experiencing better mental health.So why the fears about screen time? Odgers argues that the methods for previous studies may have led to false conclusions. When given a survey, the kids were often asked to recall, over the past six months, “How often are you online?” and “Have you ever felt depressed”. And the relation between those two things has been used to spread a lot of fear around the connection between social media use and things like depression, yet 99.5% of the reasons that kids differ in their depression is due to something other than the time they spend online.1. The new study is mainly about the relation between ________.A. kids, screen time and their eyesightB.kids’ screen time and their depressionC. social media use and kids’ mental healthD. Internet environment and kids’ mental health2. What does Odgers think of the message parents received?A.It misleads people.B.It makes much sense.C.It was confirmed by science.D.It reveals parents, ignorance.3. What kind of kids bear better mental health?A. Kids spending less time online.B. Kids staying unconnected offline.C. Kids shutting off social media.D. Kids positively using digital technology.4. What’s the main purpose of the text?A. To present a social phenomenon.B. To challenge a common belief.C.To draw attention to kids,health.D.D. To encourage more screen time.（D）Next day, Jo wanted to get out of the house, so she picked up her skates and went next door to ask Laurie to take her skating.Amy heard them going. “Jo promised to take me with her next time!” she complained.“It’s hard for her to forgive you, Amy,”said Meg. “Go after them and wait until Jo is enjoying herself, then give her a kiss or do something kind.”It was not far to the river, but Jo and Laurie were already skating when Amy arrived. Jo saw Amy but turned away.Laurie was carefully skating along the edge of the ice and didn’t see the younger girl.Amy put her skates on and stood on the ice.“Keep near the edge. The i ce isn’t safe in the middle.” Laurie called to Jo, then he disappeared round the first bend in the river.Jo heard, but Amy did not. Jo realized that Amy probably hadn’t heard, but she said nothing and skated after Laurie. “Let Amy look after herself!” Jo thought.Amy skated out towards the smoother ice in the middle of the river. Jo reached the bend, and for a moment she stood still,a strange feeling in her heart. Something made her turn round—just in time tosee Amy throw up her hands and go crashing through the ice into the cold water!Amy gave a cry that made Jo’s heart stop with fear. She tried to call Laurie,but her voice was gone, and for a second she could only stand and stare at the little blue hood(帽子) of Amy’s coat above the black water.Suddenly, Laurie skated past her and shouted, “Bring a piece of wood from the side of the river, quickly!”Wild with fear, Jo fetched some wood and pulled it across the ice, while Laurie held Amy’s head above the water. Together, they got her out.She was more frightened than hurt, and was quickly taken home. They covered her in blankets and tried to calm her, and after a little while she fell asleep in front of the warm fire. Later, when everything was quiet, Jo asked her mother, “Are you sure she is safe ?”“Quite safe, dear. It was sensible together home as quickly as you did.”“Laurie did it all,” said Jo. “Mother, if she should die, it will be my fault. I get angry so quickly. Oh, why can’t I be more like you?”“I get angry nearly every day of my life,Jo,” said Mrs March, “but I’ve learned not to show it. I’ve learned to stop myself saying the angry words that come to my lips, and you must try to do the same, my dear.”1.Why did Jo turn away the moment she saw Amy?A. She heard Laurie calling her.B. She had to adjust her skates.C. She would not forgive Amy.D. She regretted not keeping her promise.2. Which of the following happened first?A. Laurie and Jo got Amy out of the river.B. Laurie warned Jo to keep near the edge.C. Jo’s heart stopped with fear hearing Amy’s cry.D. Amy skated out towards the middle of the river.3. How did Jo probably feel after knowing Amy was safe and sound?A. Relieved.B. Disappointed.C.Annoyed.D. Proud.4. Which ending is the writer most likely to add to the story?A. Mr. March blamed Jo so hard that she cried.B. Laurie thought ill of Jo and broke up with her.C. Amy was grateful to learn a lesson from the accident.D. Everything was forgiven and forgotten when Amy woke up.（E）Streaming（流媒体）first became popular in 2005, thanks to YouTube. Nowadays nearly three quarters of American households subscribe to at least one video streaming service. With almost 200 million subscribers worldwide and a billion hours of content viewed each week, Netflix is by far the biggest paid service. No. 2 is Amazon Prime Video. But for every Goliath, there are a hundred Davids. Many smaller streaming services show nothing but sports, classic movies, or Japanese anime (动画片).In the early days of steaming the appeal was the lower cost, and it still is. The averagestreamer spends $37 a month (and subscribes to three streaming platform, while the average cable （有线电视）user pays more than $200 per month. Still streaming has become more expensive in recent years. In 2019, Netflix raised the price of its basic service 12.5 percent, to $8.99 a month. A quarter of is subscribers,who protested price increases, said they would cancel their subscriptions. Few did.A major reason: Streaming networks have become home to many of the most popular TV series, including recent Emmy winners. They offer full-length feature films as well, and last year, Netflix received more Oscar nominations（提名）than any other media company. In fact, streaming has changed the Oscar competition, at least for this year. Usually only films shown in theaters are considered, but because of the Coronavirus, all movies released online in 2020 are qualified for the 2021 Academy Awards. That shift is especially good news for Disney, which is putting the much anticipated movie Mulan on its new streaming service, Disney+. But watching Mulan from your own home will cost $29.99 —on top of the service’s monthly fee of $6.99.Too much streaming can have its disadvantages, however. There are those who binge-watch, a term Merriam-Webster added in 2017 with the definition “to watch many or all episodes of (a TV series) on end.” Alejandro Fragoso from New York holds the Guinness World Record: 94 straight hours.1. What do the underlined words “Goliath” and “David”in Paragraph 1 refer to?A. TV viewers.B. TV programs.C. Streaming subscribers.D.Streaming services.2. Why did most Netflix subscribers continue their subscriptions?A. They cannot go without it.B. They think the low cost is a thing of the past.C. Netflix has controlled the market.D. They think it is good value for money.3. What does the good news in Paragraph 3 mean to Disney？A. The movie Mulan can be released on Disney+.B. The movie Mulan will generate great profits.C. The movie Mulan can compete for an Oscar.D. The movie Mulan will win an Oscar award.4. What do binge-watchers tend to do?A. They start a new life.B. They watch TV series continuously.C. They break world records.D.They watch TV series aimlessly（F）We humans love to stare into our smart devices. We gaze for hours－about 10 hours and 39 minutes a day—at our computers, smartphones, tablets and televisions. Is all this staring bad for us? It might be, mainly because as we stare at our devices we are exposing ourselves to blue light.Blue light is a type of electromagnetic(电磁的) radiation with a very short wavelength that produces a high amount of energy. While it's true that light can damage our eyes under certain circumstances, there's no scientific evidence suggesting that blue light is harmful to our eyes. But many people still think it is, which is why bluelightblocking glasses are so popular. So do the glasses work?“Everyone is very concerned that blue light may be causing damage to the eye, but there's no evidence that it may be causing serious damage，” Dr.Rahul Khurana, clinical spokesman for the American Academy of Ophthalmology, told Business Insider.Blue light exposure is nothing new. In fact, the sun is the largest source of blue light. Moreover, blue light is also present in LED light. But if blue light isn't harmful, then why are we constantly rubbing our eyes when we're looking at our screens? The answer is eyestrain(眼疲劳)：More than 60 percent of people experience eye problems associated with digital eyestrain. And blue light, it seems, isn't the cause. Instead，our eyes are so strained because most of us blink less when we stare at our digital devices. So if eyestrain is the issue, bluelightblocking glasses are probably of little use.1．What do we know about blue light?A．It is a kind of nuclear radiation.B．It has the shortest wavelength.C．It may come from electronic devices.D．It consumes a great deal of energy.2．What causes the popularity of bluelightblocking glasses?A．Evidence of their benefits to eyes.B．Belief in blue light's harmful effect.C．Widespread use of smart devices.D．Scientific understanding of blue light.3．What can be inferred from Paragraph 4?A．Blue light exposure is hardly avoidable.B．Eye problems are not easy to deal with.C．Blue light may connect with tired eyes.D．Rubbing eyes makes people strained.4．According to the text, wearing bluelightblocking glasses may be ____.A．tiring B．harmful C．useless D．beneficial参考答案A1.B根据题干定位到第一段第二句But the discovery of a woman buried 9,000years ago in the Andes Mountains with weapons and hunting tools challenges this widely accepted view（但在安第斯山脉发现了一名9000年前被埋在地下的妇女，她身上还带着武器和狩猎工具，这对被广泛接受的观点提出了挑战），再根据本段的最后一句suggested she hunted big-game animals by spear (矛)throwing，可知，暗示了她通过投掷长矛来猎杀大型猎物。

专题十六阅读理解之科普类说明文1.【2015·湖北卷】DThe oddness of life in space never quite goes away. Here are some examples.First consider something as simple as sleep. Its position presents its own challenges. The main question is whether you want your arms inside or outside the sleeping bag. If you leave your arms out, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled （芭蕾）dancer. “I’m an inside guy,” Mike Hopkins says, who returned from a six-month tour on the International Space Station. “I like to be wrapped up.”On the station, the ordinary becomes strange. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it’s just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale (呼气) has a tendency to form an invisible （隐形的）cloud around you head. You can end up with what astronauts call a carbon-dioxide headache.Leroy Chiao, 54, an American retired astronaut after four flights, describes what happens even before you float out of your seat,”Your inner ear thinks your’re falling . Meanwhile your eyes are telling you you’re standing straight. That can be annoying—that’s why some people feel sick.” Within a couple days —truly terrible days for some —astronauts’ brains learn to ignore the panicky signals from the inner ear, and space sickness disappears.Space travel can be so delightful but at the same time invisibly dangerous. For instance, astronauts lose bone mass. That’s why exercise is considered so vital that National Aeronautics and Space Administration (NASA) puts it right on the workday schedule. The focus on fitness is as much about science and the future as it is about keeping any individual astronauts return home, and, more importantly, how to maintain strength and fitness for the two and a half years or more that it would take to make a round-trip to Mars.is the major challenge to astronauts when they sleep in spaceA. Deciding on a proper sleep positionB. Choosing a comfortable sleeping bagC. Seeking a way to fall asleep quicklyD. Finding a right time to go to sleep.astronauts will suffer from a carbon-dioxide headache when _____.A. the y circle around on their bikesB. they use microcomputers without a stopC. they exercise in one place for a long timeD. they watch a movie while pedalingastronauts feel sick on the station during the first few days because _____.A. their senses stop workingB. they have to stand up straightC. they float out of their seats unexpectedlyD. whether they are able to go back to the stationof the NASA’s major concerns about astronauts is _____.A. how much exercise they do on the stationB. how they can remain healthy for long in spaceC. whether they can recover after returning homeD. whether they are able to go back to the station【解析】试题分析：这是一篇说明文。

2022高三英语阅读专题训练之说明文（A）The third-generation hybrid rice which was developed by Yuan Longping, the "father of hybrid rice", and his team ran its first public yield monitoring from Monday to Tuesday and achieved high output. The final yield of the tested variety, G3-1S/P19, came to1046.3 kg per mu （about 667 square meters）, based on two pieces of land in Qingzhu Village under the city of Hengyang in central China's Hunan Province."Some previous high-yielding hybrid rice varieties in China took 160 to even 180 days from sowing to harvesting, while the figure was shortened to around 125 days for the new variety. This is one of the most important features of the third-generation hybrid rice that can reduce the use of pesticides（X虫剂）and fertilizers, thus reducing cost and improving production efficiency." said Qian Qian, the deputy director of the China National Rice Research Institute.Unlike the previous two generations that required a large amount of water and fertilizers as well as demanding growing conditions and technological support, the third-generation hybrid rice is easier to be cultivated（种植）by ordinary farmers. So the soil, altitude and climate of the test site were not "ideal conditions" carefully selected beforehand but were close to the paddies（稻田）of ordinary farmers.Nowadays. China's average yield of rice is about 500 kg per mu. Ordinary farmers can produce 600 kg to 700 kg of rice per mu by growing some excellent second-generation hybrid rice varieties. However, under the same planting conditions and environment, the yield of the third-generation hybrid rice could reach 800 kg per mu. China now feeds around 20 percent of the world's population with less than 9 percent of the world's arable（可耕种的）land.At present, Yuan's team has nine third-generation hybrid rice combinations under trial, which are expected to achieve commercial seed production in the following three to four years and hope to apply the technology into the research of sea rice. The third-generation hybrid rice has the comprehensive strength to promote a greener and more sustainable development of China's rice production with higher quality and yield.1．What feature of the new hybrid rice does Qian Qian mainly talk about?A．It saves a lot more water. B．It has a shorter growing period.C．It saves much more farmland. D．It achieves a higher yield.2．Why is the new hybrid rice not tested in ideal areas?A．The ordinary farmers master planting technology.B．The researchers want to reduce the experiment cost.C．The growing conditions the new hybrid rice needs are simple.D．The previous rice farming provides researchers with experience.3．What is the fourth paragraph mainly about?A．The high output of the third-generation hybrid rice.B．The future of the new hybrid rice variety.C．The advanced technology of the research on hybrid rice.D．The differences between the three hybrid rice varieties.4．Where is this text most likely from?A．A news report. B．A guide book.C．An advertisement. D．A fashion magazine.（B）The snow in Antarctica is turning green and scientists say climate change may be to blame. According to a study at the Cambridge University, microscopic algae blooms (藻类爆发) across the surface of the snow is slowly turning Antarctica’s winter white landscape green. Although microscopic, scientis ts say they’re able to see the “green snow” from space when the algae blooms all together.Researchers created a large-scale map of green snow algae along the Antarctic coast using a combination of satellite data and on-the-ground observations over the course of two summers. The study found that the green snow algae bloomed in warmer areas where the average temperatures are just above 0℃during the southern hemisphere’s (半球的) summer months from November to February.“As Antarctica warms, we predict the overall mass of snow algae will increase,” said Dr Andrew Gray, lead author of the paper, and a researcher. Researchers say larger blooms of algae can be found north of the Antarctic and South Shetland Islands, where it can spread to higher ground as the snow melts.The team also discovered some sea birds and mammals influenced the distribution of algae. Over 60% of algae blooms were found within three miles of a penguin settlement. Scientists hypothesize this may be due to their droppings which act as a “highly nutritious fertilizer.”“This is a significant advance in our understanding of land-based life on Antarctica, and how it might change in the coming years as the climate warms,” said Dr. Matt Davey in the University of Cambridge’s Department of Plant Scie nces, who led the study.1.What is turning the Antarctic snow green?A. The melting of snow.B. The blooming algae.C. The beautiful landscape.D. The balanced temperature.2.Where is microscopic algae most likely to bloom in Antarctica?A. North of the Antarctic.B. West of the South Pole.C. South of the Antarctic.D. Around the southern hemisphere.3. What does the underlined word “hypothesize” in Paragraph 4 probably mean?A.Confirm.B. Support.C. Assume.D. Warn.4. What can we learn from the text?A. Penguins feed on microscopic algae.B. Antarctic algae grow under the snow.C. Ground observation lasted for four months.D. Animal droppings contribute to the algae blooms.（C）It is generally supped that the English Romantic Movement began in 1798. However it is not a sudden outbreak but the result of long and gradual growth and development. The Ro-manticism is a literary movement which took place in Britain and throughout Europe between 1770 and 1848. Polit ically, “was inspired by the revolutions in America and France. Emo-tionally, it expressed an extreme claim of the self and the value of the individual experience to-gether with the sense of the limitless and the transcendental(超验的). In Britain, Romantic writers of the first generation included Wordsworth and Coleridge, Blake and Burns. The sec-ond generation of British Romantics—Byron, Shelley and Keats absorbed these influences, wrote quickly, travelled widely and their life stories and letters became almost as important for Romanticism as their poetry.Romanticism does not mean one thing or one characteristic. It is, in fact, a collective term to mean certain characteristics? such as mysticism, humanism, super naturalism? love of beauty, love of nature, love of equality. The chief characteristics of romantic poetry are as the following：Subjectivity：All romantic literature is subjective. It is an expression of the inner urges of the soul of the artist The poet gives free expression to his feelings, emotions, experiences, thoughts and ideas and. does not care for rules and regulations. The emphasis is laid on inspiration and intuition(直觉).Love of Nature: Enthusiasm for the beauties of the external world characterizes all romantic poetry. Romantic poetry carries us away from the uncomfortable atmosphere of cities into the fresh company of the outdoor world. All poets were lovers of nature and looked at the beautiful aspects of nature. To them, nature was a friend, a lover, a mother, sister and a teacher.Imagination and Emotion：The romantic poets laid emphasis on imagination and emotion. The Wordsworth's romantic poem I Wandered Lonely as a Cloud deals with subjects of creative imagination, childhood memories, beauty of nature, the role of nature as a guiding spirit.1. What can we know about the English Romantic Movement?A. It emphasized the value of policies.B. It originated at the end of 18th century.C. It was affected by the Russian revolution.D. It was caused by sudden growth and development.2. What does Romanticism show?A. It hides the inner desires of poets.B. It focuses on inspiration and reality.C. It is controlled by rules and regulations.D. It is a term involving some certain features.3. What does romantic poetry play a role in?A. Making us always be enthusiastic.B. Showing us another way to read novels.C. Keeping us enjoying the company of nature.D. Asking us to respect city atmosphere.4. How does the author explain the feature of Imagination and Emotion?A. By giving an example.B. By using a quotation.C. By asking a question.D. By making a comparison.（D）The scientists who re-engineered the plastic-eating enzyme(酶) PETase have now created a new enzyme called “cocktail” , which can digest plastic up to six ti mes faster.PETase breaks down PET back into its building blocks, creating an opportunity to recycle plastic and reduce plastic pollution. PET is the most common thermoplastic(热塑性塑料) used to make single-use drinks bottles, which takes hundreds of years to break down in the environment, but PETase can shorten this time to days. The initial discovery set up the prospect of a revolution in plastic recycling, creating a potential low-energy solution to tackle plastic waste.Now, the same trans-Atlantic team hav e combined PETase and its “partner”, a second enzyme called MHETase, to generate much bigger improvements: simply mixing PETase with MHETase doubled the speed of PET breakdown, and engineering a connection between the two enzymes to create a “super-enzyme”, increased this activity by a further three times.The team was co-led by the scientists who engineered PETase, Professor John McGeehan and Dr Gregg Beckham. Professor McGeehan said: “Gregg and I were chatting about how PETase attacks the surface of the plastics and MHETase chops things up further, so it seemed natural to see if we could use them together. Our first experiments showed that they did work better together, so we decided to physically link them. It took a great deal of work, but it was worth the effort —we were delighted to see that our new enzyme is up to three times faster than the separate enzymes.”The original PETase enzyme discovery indicated the first hope that a solution to the global plastic pollution problem might be within grasp, though PETase alone is not yet fast enough to handle the tons of PET bottles. Combining it with a second enzyme, and finding together they work even faster, means another leap forward has been taken towards finding a solution to plastic waste. PETase and the new combined MHETase-PETase both work by digesting PET plastic. This allowsfor plastics to be made and reused endlessly, reducing our reliance on fossil(化石) resources.1. What can we learn about “cocktail” from the text?A. It doubles the breakdown of plastics.B. It takes hundreds of years to break down.C. It contributes to breaking down plastic quickly.D. It deals with the plastic waste three times faster.2. What is the second paragraph mainly about?A. A new study of PET.B. The breakdown of PET.C. The discovery of PETase.D. The functions of PETase.3. What d oes the underlined word “It” in Paragraph 4 refer to?A. Co-leading the trans-Atlantic team.B. Combining PETase and MHETase.C. Attacking the surface of the plastics.D. Talking about conducting experiments.4. What can we infer from the text?A. PET pollution is no longer a difficult problem to deal with.B. New enzyme is speeding up our reliance on fossil resources.C. MHETase-PETase makes the world free from plastic pollution.D. Plastic-eating enzyme “cocktail” promises new hope for plastic waste.（E）In a new blog post for the International Monetary Fund, four researchers presented their findings from a working paper that examines the current relationship between finance and tech as well as its potential future.Gazing into their crystal ball, the researchers see the possibility of using the data from your browsing, search, and purchase history to create a more accurate mechanism for determining the credit rating of an individual or business. They believe that this approach could result in greater lending to borrowers who would potentially be denied by traditional financial institutions.At its heart, the paper is trying to wrestle with the dawning notion that the institutional banking system is facing a serious threat from tech companies like Google, Facebook, and Apple. The researchers identify two key areas in which this is true: Tech companies have greater access to soft-information, and messaging platforms can take the place of the physical locations that banks rely on for meeting with customers.The concept of using your web history to inform credit ratings is framed around the notion that lenders rely on hard-data that might hide the worthiness of a borrower or paint an unnecessarily bad picture during hard times. Citing soft-data points like "the type of browser and hardware used to access the internet, the history of online searches and purchases" that could be included in evaluating a borrower, the researchers believe that when a lender has a closer relationship with the potential client's history, they might be more willing to cut them some slack."Banks tend to cushion credit terms for their long-term customers during downturns," the paper's authors write. This is because they have a history and relationship with the customer.The researchers acknowledge that there will be privacy and policy concerns related to including this kind of soft-data in credit analysis. Getting the soft-data points would probably require companies like Facebook and Apple to loosen up their standards on linking unencrypted information with individual accounts. How they might share information with other institutions would be its own can of worms.1. What is the approach put forward by the researchers?A. Replacing banks with soft information.B. Lending money by predicting the future.C. Determining credit ratings by web history.D. Facing the threat posed by high-tech companies.2. Why do they advocate the new way of rating the borrower’s credit?A. Traditional finance refuse to lend money.B. The new approach helps reduce burden on banks.C. The type of hardware misleads the lender’s judgement.D. Soft information better reflects the truth than hard data.3. Which is the closest in meaning with the underlined phrase in Paragraph 4?A. Be less strict.B. Share interests.C. Forgive others’ fault.D. Cut a piece of bread.4. What do the researchers worry about?A. Banks will break up with customers.B. High tech companies will be in a mess.C. Sharing information may cause problems of privacy.D. Competition between tech companies will be more fierce.（F）At your next meeting, wait for a pause in conversation and try to measure how long it lasts.Among English speakers, chances are that it will be a second or two at most. But while this pattern may be universal, our awareness of silence differs dramatically across cultures.What one culture considers a confusing or awkward pause may be seen by others as a valuable moment of reflection and sign of respect for what the last speaker has said. Research in Dutch and also in English found that when a silence in conversation stretches to four seconds, people start to feel uneasy. In contrast, a separate study of business meetings found that Japanese people are happy with silences of 8.2 seconds —nearly twice as long as in Americans’ meetings.In Japan, it is recognized that the best communication is when you don’t speak at all. It’s already a failure to understand each other by s peaking because you’re repairing that failure by using words.In the US, it may originate from the history of colonial (殖民地) America as a crossroads of many different races. When you have a complex of difference, it’s hard to establish common understanding unless you talk and there’s understandably a kind of anxiety unless people are verbally engaged to establish a common life. This applies also to some extent to London.In contrast, when there’s more homogeneity, perhaps it’s easier for some kinds of silen ce to appear. For example, among your closest friends and family it’s easier to sit in silence than with people you’re l ess well acquainted with.1. Which of the following people might have the longest silence in conversation?A. The Dutch.B. Americans.C. The English.D. The Japanese.2. What might the Japanese agree with in a conversation?A. Speaking more gives the upper hand.B. Speak out what you have in your mind.C. Great minds think alike without words.D. The shorter talking silence, the better.3. What can we learn from the text?A. A four second silence in conversation is universal.B. It’s hard for Americans to reach a common agreement.C. English speakers are more talkative than Japanese speakers.D. The closer we and our family are, the easier the silence appears.4. What does the underlined word “homogeneity” in the last paragraph mean?A Similarity. B. Contradiction.C. Diversity.D.

2020年高考英语真题分类汇编专题06：说明文类阅读理解一、阅读理解1.阅读理解According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the "I'll have what she's having" effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?（1）What is the recent study mainly about?A.Food safety.B.Movie viewership.C.Consumer demand.D.Eating behavior.（2）What does the underlined word "beanpoles" in paragraph 1 refer to?A.Big eaters.B.Overweight persons.C.Picky eaters.D.Tall thin persons.（3）Why did the researchers hire the actor?A.To see how she would affect the participants.B.To test if the participants could recognize her.C.To find out what she would do in the two tests.D.To study why she could keep her weight down.（4）On what basis do we "adjust the influence" according to the last paragraph?A.How hungry we are.B.How slim we want to be.C.How we perceive others.D.How we feel about the food.2.阅读理解How to Use a Modern Public LibraryHas it been a while since your last visit to a public library? If so, you may be surprised to learn that librarieshave changed for the better. It's been years since they were dusty little rooms with books. They have transformed themselves into places where you can develop your love of knowledge meet interesting people, or find out how to start a business.Check out a book. While libraries still loan out(出借)books, you'll find it easier to get a copy of whatever you're looking for, thanks to a cooperative network of area libraries. Via such networks, libraries share their books with each other through the use of delivery vehicles. Once the book you've requested is delivered to the nearest branch, they will inform you by e-mail, so you can pick it up.Check out other items. The library is now a multimedia zone, loaded with information in many formats(载体形式). You can borrow movies on DVDs, music on CDs, and popular magazines. Some libraries even loan out toys and games. If a popular magazine you want isn't offered and the library keeps a list of such requests, they may bring it in when enough interest is shown.Join targeted reading groups. Libraries will often hold reading-group sessions targeted to various age groups. Perhaps you'd like to learn a language or improve your English. The library may sponsor a language group you could join. If you have difficulties reading, ask about special reading opportunities. Your library might be able to accommodate you. And you might find it relaxing to bring your small kid to a half-hour Story Time while you sit quietly in a corner with a good book.Start a business using the help of your local library. If you want to have a business of your own, your local library can become a launch space for it. In library books and computers, you can find information on starting a business. Many libraries will help you with locally supplied information about business management shared through chambers of commerce(商会)and government agencies, and they will offer printing, faxing and database services you need.（1）Public libraries connected by a cooperative network benefit readers by______.A.sharing their books on the InternetB.giving access to online reading at a library branchC.sending a needed book to a library branch nearbyD.making the checkout procedures diverse（2）According to Paragraph 3, what items may be checked out from a public library?A.A magazine and an e-book.B.A game and an oil painting.C.A music CD and a kid's toy.D.A DVD and a video player（3）As is described in Paragraph 4, taking a small kid to a half-hour Story Time allows ______.A.the kid to learn a new languageB.the parent to enjoy quiet readingC.the kid to overcome reading difficultiesD.the parent to meet their program sponsor（4）Your local library can help you start a business by ______.A.providing relevant information and supporting servicesB.offering professional advice on business managementC.supplying useful information of your potential buyersD.arranging meetings with government officials（5）What is the purpose of the passage?A.To point out the importance of public libraries.B.To encourage people to work in public libraries.C.To introduce the improved services of public libraries.D.To call for the modernization of public library systems.3.阅读理解For people, who are interested in sound, the field of sound technology is definitely making noise. In the past, sound engineers worked in the back rooms of recording studios, but many of today's sound professionals are sharing their knowledge and experience with professionals in other fields to create new products based on the phenomenon we call sound.Sound can be used as a weapon. Imagine that a police officer is chasing a thief. The thief tries to escape. And the officer can't let him get away. He pulls out a special device, points it at the suspect, and switches it on. The thief drops to the ground. This new weapon is called a Long Range Acoustic Device(LRAD, 远程定向声波发射器). It produces a deafening sound so painful that it temporarily disables a person. The noise from the LRAD is directed like a ray of light and travels only into the ears of that person, but it is not deadly.For those who hunger for some peace and quiet, sound can now create silence. Let's say you are at the airport, and the little boy on the seat next to you is humming(哼唱) a short commercial song. He hums it over and over again, and you are about to go crazy. Thanks to the Silence Machine, a British invention, you can get rid of the sound without upsetting the boy or his parents. One may wonder how the Silence Machine works. Well, it functions by analyzing the waves of the incoming sound and creating a second set of outgoing waves. The two sets of waves cancel each other out. Simply turn the machine or point it at the target, and your peace and quiet comes back.Directed sound is a new technology that allows companies to use sound in much the same way spotlights(聚光灯) are used in the theater. A spotlight lights up only one section of a stage; similarly, "spotsound" creates a circle of sound in on targeted area. This can be useful for businesses such as restaurants and stores because it offers a new way to attract customers. Restaurants can offer a choice of music along with the various food choices on the menu, allowing customers more control over the atmosphere in which they are dining. Directed sound is also beginning to appear in shopping centers and even at homes.（1）What could be inferred from Paragraph 2 about the effect of the LRAD?A.It causes temporary hearing loss.B.It slows down a running man.C.It makes it easy to identify a suspect.D.It keeps the suspect from hurting others.（2）The Silence Machine is a device specially designed to ________.A.silence the people around youB.remove the sound of commercialsC.block the incoming sound wavesD.stop unwanted sound from affecting you（3）What feature do spotsounds and spotlights share?A.They travel in circles.B.They clear the atmosphere.C.They can be transformed into energy.D.They can be directed onto a specific area.（4）Directed sound can be used for ________.A.creative designs of restaurant menusB.ideal sound effects on the theater stageC.different choices of music for businessesD.strict control over any suspicious customer（5）What does the passage focus on?A.How professionals invented sound products.B.Inventions in the field of sound technology.C.The growing interest in the study of sound.D.How sound engineers work in their studios.4.阅读理解The traffic signals along Factoria Boulevard in Bellevue, Washington, generally don't flash the same length of green twice in a row, especially at rush hour. At 9:30am, the full red/yellow/green signal cycle might be 140 seconds. By 9:33am, a burst of additional traffic might push it to 145 seconds. Less traffic at 9:37am could push it down to 135. Just like the traffic itself, the timing of the signals changes.That is by design. Bellevue, a fast-growing city just east of Seattle, uses a system that is gaining popularity around the US: intersection(十字路口) signals that can adjust in real time to traffic conditions. These lights, known as adaptive signals, have led to significant declines in both the trouble and cost of travels between work and home."Adaptive signals can make sure that the traffic demand that is there is being addressed," says Alex Stevanovic, a researcher at Florida Atlantic University.For all of Bellevue's success, adaptive signals are not a cure-all for jammed roadways. Kevin Balke, a research engineer at the Texas A&M University Transportation Institute, says that while smart lights can be particularly beneficial for some cities, others are so jammed that only a sharp reduction in the number of cars on the road will make a meaningful difference. "It's not going to fix everything, but adaptive signals have some benefits for smaller cities," he says.In Bellevue, the switch to adaptive signals has been a lesson in the value of welcoming new approaches. In the past, there was often an automatic reaction to increased traffic: just widen the roads, says Mark Poch, the Bellevue Transportation Department's traffic engineering manager. Now he hopes that other cities will consider making their streets run smarter instead of just making them bigger.（1）What does the underlined word "that" in paragraph 2 refer to?A.Increased length of green lights.B.Shortened traffic signal cycle.C.Flexible timing of traffic signals.D.Smooth traffic flow on the road.（2）What does Kevin Balke say about adaptive signals?A.They work better on broad roads.B.They should be used in other cities.C.They have greatly reduced traffic on the road.D.They are less helpful in cities seriously jammed.（3）What can we learn from Bellevue's success?A.It is rewarding to try new things.B.The old methods still work today.C.I pays to put theory into practice.D.The simplest way is the best way.5.阅读理解Challenging work that requires lots of analytical thinking, planning and other managerial skills might help your brain stay sharp as you age, a study published Wednesday in the journal Neurology suggests.Researchers from the University of Leipzig in Germany gathered more than 1, 000 retired workers who were over age 75 and assessed the volunteers' memory and thinking skills through a battery of tests. Then, for eight years, the scientists asked the same group to come back to the lab every 18 months to take the same sorts of tests.Those who had held mentally stimulating(刺激), demanding jobs before retirement tended to do the best on the tests. And they tended to lose cognitive(认知) function at a much slower rate than those with the least mentally challenging jobs. The results held true even after the scientists accounted for the participants' overall health status."This works just like physical exercise," says Francisca Then, who led the study. "After a long run, you mayfeel like you're in pain, you may feel tired. But it makes you fit. After a long day at work-sure, you will feel tired, but it can help your brain stay healthy. "It's not just corporate jobs, or even paid work that can help keep your brain fit, Then points out. A waiter's job, for example, that requires multitasking, teamwork and decision-making could be just as stimulating as any high-level office work. And "running a family household requires high-level planning and coordinating(协调), " she says. "You have to organize the activities of the children and take care of the bills and groceries."Of course, our brains can decline as we grow older for lots of reasons-including other environmental influences or genetic factors.

For many British people, that can apply to institutions and objects that represent their country's past-age-old castles, splendid homes… and red phone boxes.Beaten first by the march of technology and lately by the terrible weather in junkyards (废品场), the phone boxes representative of an age are now making something of a comeback. Adapted in imaginative ways, many have reappeared on city streets and village greens housing tiny cafes, cellphone repair shops or even defibrillator machines (除颤器).The original iron boxes with the round roofs first appeared in 1926. They were designed by Giles Gilbert Scott, the architect of the Battersea Power Station in London. After becoming an important part of many British streets, the phone boxes began disappearing in the 1980s, with the rise of the mobile phone sending most of them away to the junkyards.About that time, Tony Inglis' engineering and transport company got the job to remove phone boxes from the streets and sell them out. But Inglis ended up buying hundreds of them himself, with the idea of repairing and selling them. He said that he had heard the calls to preserve the boxes and had seen how some of them were listed as historic buildings.As Inglis and, later other businessmen, got to work, repurposed phone boxes began reappearing in cities and villages as people found new uses for them. Today, they are once again a familiar sight, playing roles that are often just as important for the community as their original purpose.In rural areas, where ambulances can take a relatively long time to arrive, the phone boxes have taken on a lifesaving role. Local organizations can adopt them for l pound, and install defibrillators to help in emergencies.Others also looked at the phone boxes and saw business opportunities. LoveFone, a company that advocates repairing cellphones rather than abandoning them, opened a mini workshop in a London phone box in 2016.The tiny shops made economic sense, according to Robert Kerr, a founder of LoveFone. He said that one of theboxes generated around $13,500 in revenue a month and cost only about $400 to rent.Inglis said phone boxes called to mind an age when things were built to last. I "like what they are to people, and I enjoy bringing things back," he said.（1）The phone boxes are making a comeback ______.A.to form a beautiful sight of the cityB.to improve telecommunications servicesC.to remind people of a historical periodD.to meet the requirement of green economy（2）Why did the phone boxes begin to go out of service in the 1980s?A.They were not well-designed.B.They provided bad services.C.They had too short a history.D.They lost to new technologies.（3）The phone boxes are becoming popular mainly because of ______.A.their new appearance and lower pricesB.the push of the local organizationsC.their changed roles and functionsD.the big funding of the businessmen7.阅读理解For those who can stomach it, working out before breakfast may be more beneficial for health than eating first, according to a study of meal timing and physical activity.Athletes and scientists have long known that meal timing affects performance. However, far less has been known about how meal timing and exercise might affect general health.To find out, British scientists conducted a study. They first found 10 overweight and inactive but otherwise healthy young men, whose lifestyles are, for better and worse, representative of those of most of us. They tested the men's fitness and resting metabolic (新陈代谢的) rates and took samples (样品) of their blood and fat tissue.Then, on two separate morning visits to the scientists' lab, each man walked for an hour at an average speed that, in theory should allow his body to rely mainly on fat for fuel. Before one of these workouts, the men skipped breakfast, meaning that they exercised on a completely empty stomach after a long overnight fast (禁食). On the other occasion, they ate a rich morning meal about two hours before they started walking.Just before and an hour after each workout, the scientists took additional samples of the men's blood and fat tissue.Then they compared the samples. There were considerable differences. Most obviously, the men displayed lower blood sugar levels at the start of their workouts when they had skipped breakfast than when they had eaten. As a result, they burned more fat during walks on an empty stomach than when they had eaten first. On the other hand, they burned slightly more calories (卡路里), on average, during the workout after breakfast than after fasting.But it was the effects deep within the fat cells that may have been the most significant, the researchers found. Multiple genes behaved differently, depending on whether someone had eaten or not before walking. Many of these genes produce proteins (蛋白质) that can improve blood sugar regulation and insulin (胰岛素) levels throughout the body and so are associated with improved metabolic health. These genes were much more active when the men had fasted before exercise than when they had breakfasted.The implication of these results is that to gain the greatest health benefits from exercise, it may be wise to skip eating first.（1）The underlined expression "stomach it" in Paragraph 1 most probably means "______".A.digest the meal easilyB.manage without breakfastC.decide wisely what to eatD.eat whatever is offered（2）Why were the 10 people chosen for the experiment?A.Their lifestyles were typical of ordinary people.B.Their lack of exercise led to overweight.C.They could walk at an average speed.D.They had slow metabolic rates.（3）What happened to those who ate breakfast before exercise?A.They successfully lost weight.B.They consumed a bit more calories.C.They burned more fat on average.D.They displayed higher insulin levels.（4）What could be learned from the research?A.A workout after breakfast improves gene performances.B.Too much workout often slows metabolic rates.C.Lifestyle is not as important as morning exercise.D.Physical exercise before breakfast is better for health.8.阅读理解I was in the middle of the Amazon (亚马逊) with my wife, who was there as a medical researcher. We flew ona small plane to a faraway village. We did not speak the local language, did not know the customs, and more often than not, did not entirely recognize the food. We could not have felt more foreign.We were raised on books and computers, highways and cell phones, but now we were living in a village without running water or electricity It was easy for us to go to sleep at the end of the day feeling a little misunderstood.Then one perfect Amazonian evening, with monkeys calling from beyond the village green, we played soccer. I am not good at soccer, but that evening it was wonderful. Everyone knew the rules. We all spoke the same language of passes and shots. We understood one another perfectly. As darkness came over the field and the match ended, the goal keeper, Juan, walked over to me and said in a matter-of-fact way, "In your home, do you have a moon too?" I was surprised.After I explained to Juan that yes, we did have a moon and yes, it was very similar to his, I felt a sort of awe (敬畏) at the possibilities that existed in his world. In Juan's world, each village could have its own moon. In Juan's world. the unknown and undiscovered was vast and marvelous. Anything was possible.In our society, we know that Earth has only one moon. We have looked at our planet from every angle and found all of the wildest things left to find. I can, from my computer at home, pull up satellite images of Juan's village. There are no more continents and no more moons to search for, little left to discover. At least it seems that way.Yet, as I thought about Juan's question, I was not sure how much more we could really rule out. I am, in part, an ant biologist, so my thoughts turned to what we know about insect life and I knew that much in the world of insects remains unknown. How much, though? How ignorant (无知的) are we? The question of what we know and do not know constantly bothered me.I began collectin g newspaper articles about new species, new monkey, new spider…, and on and on they appear. My drawer quickly filled. I began a second drawer for more general discoveries: new cave system discovered with dozens of nameless species, four hundred species of bacteria found in the human stomach. The second drawer began to fill and as it did I wondered whether there were bigger discoveries out there, not just species, but life that depends on things thought to be useless, life even without DNA. I started a third drawer forthese big discoveries. It fills more slowly, but all the same, it fills.In looking into the stories of biological discovery, I also began to find something else, a collection of scientists, usually brilliant occasionally half-mad, who made the discoveries. Those scientists very often see the same things that other scientists see, but they pay more attention to them, and they focus on them to the point of exhaustion (穷尽), and at the risk of the ridicule of their peers. In looking for the stories of discovery, I found the stories of these people and how their lives changed our view of the world.We are repeatedly willing to imagine we have found most of what is left to discover. We used to think that insects were the smallest organisms (生物), and that nothing lived deeper than six hundred meters. Yet, when something new turns up, more often than not, we do not even know its name.（1）How did the author feel on his arrival in the Amazon?A.Out of place.B.Full of joy.C.Sleepy.D.Regretful.（2）What made that Amazonian evening wonderful?A.He learned more about the local language.B.They had a nice conversation with each other.C.They understood each other while playing.D.He won the soccer game with the goal keeper.（3）Why was the author surprised at Juan's question about the moon?A.The question was too straightforward.B.Juan knew so little about the world.C.The author didn't know how to answer.D.The author didn't think Juan was sincere.（4）What was the author's initial purpose of collecting newspaper articles?A.To sort out what we have known.B.To deepen his research into Amazonians.C.To improve his reputation as a biologist.D.To learn more about local cultures.（5）How did those brilliant scientists make great discoveries?A.They shifted their viewpoints frequently.B.They followed other scientists closely.C.They often criticized their fellow scientists.D.They conducted in-depth and close studies.（6）What could be the most suitable title for the passage?A.The Possible and the Impossible.B.The Known and the Unknown.C.The Civilized and the Uncivilized.D.The Ignorant and the Intelligent.9.阅读理解With the young unable to afford to leave home and the old at risk of isolation(孤独), more families are choosing to live together.The doorway to peace and quiet, for Nick Bright at least, leads straight to his mother-in-law, she lives on the ground floor, while he lives upstairs with his wife and their two daughters.Four years ago they all moved into a three-storey Victorian house in Bristol — one of a growing number of multigenerational families in the UK living together under the same roof. They share a front door and a washingmachine, but Rita Whitehead has her own kitchen, bathroom, bedroom and living room on the ground floor."We floated the idea to my mum of sharing at a house," says Kathryn Whitehead. Rita cuts in: "We spoke more with Nick because I think it's a big thing for Nick to live with his mother-in-law."And what does Nick think? "From my standpoint, it all seems to work very well. Would I recommend it? Yes, I think I would."It's hard to tell exactly how many people agree with him, but research indicates that the numbers have been rising for some time. Official reports suggest that the number of households with three generations living together had risen from 325,000 in 2002 to 419,000 in 2013.Other varieties of multigenerational family are more common. Some people live with their elderly parents; many more adult children are returning to the family home, if they ever left. It is said that about 20% of 25-34-year-olds live with their parents, compared with 16% in 1991.The total number of all multigenerational households in Britain is thought to be about 1.8 million.Stories like that are more common in parts of the world where multigenerational living is more firmly rooted. In India, particularly outside cities, young women are expected to move in with their husband's family when they get married.（1）Who mainly uses the ground floor in the Victorian house in Bristol?A.Nick.B.Rita.C.KathrynD.The daughters.（2）What is Nick's attitude towards sharing the house with his mother-in -law?A.Positive.B.Carefree.C.Tolerant.D.Unwilling.（3）What is the author's statement about multigenerational family based on?A.Family traditions.B.Financial reports.C.Published statistics.D.Public opinions.（4）What is the text mainly about?A.Lifestyles in different countries.B.Conflicts between generations.C.A housing problem in Britain.D.A rising trend of living in the UK.10.阅读理解We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle -raising people in East Africa and northern Europe have gained a mutation (突变) that helps them digest milk as adults.On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation - not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, they've also built houses on stilts (支柱) in coastal waters. "They are simply a stranger to the land," said Redney C. Jubilado, a University of Hawaii researcher who studies the Bajau.。

专题卷三阅读理解之说明文1．阅读理解阅读下列短文,从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

Being physically active three times a week reduces the odds of being depressed by about 16%, according to new UCL research carried out as part of the Public Health Research Center.The study, published in JAMA Psychiatry, found a two-way relationship between depression and physical activity. People who increased their weekly activity reported fewer depressive symptoms but those with more depressive symptoms were less active, particularly at younger ages.Researchers followed 11,135 people born in 1958 up until the age of 50, recording depressive symptoms and levels of physical activity at regular intervals in adulthood. They found that each additional activity period per week reduced odds of depression by 6%. In England 19% of men and 26% of women are currently classed as “inactive”, and this study suggests that activity could significantly improve their mental as well as physical health.“Assuming the association is causal, physical activity has a protective effect against depression. If an adult between their twenties and forties who isn’ t physically active became active 3 times per week, they would reduce their risks of depression by about 16%.” says Dr. Snehal of the UCL Institute of Child Heal th, lead author of the study.Professor Mark, Director of the Public Health Research Center, said, “Many people are already aware of the benefits of physical activity on their general health, but now we are seeing more evidence that suggest it also has a positive effect on a person’s mental well-being. The latest research highlights just how important it is to ensure that people are working and living in environments that allow them to be both physically active and mentally healthy.”1.What is the author’s purpose in writing the passage?A. To tell us a fun story about how to protect us against depression.B. To introduce a research on the link between activity and depression.C. To persuade readers to increase their weekly activity.D.

重难点03 阅读理解之说明文【命题趋势】最近五年，说明文的出现变化不大，一直很稳定，选材通常是各学科的前沿问题；高科技领域的科研成果；人们比较关心的社会问题；人文方面的经典。

由于阅读理解题的设置采用渐进式，即由简到难的方式，因此说明文是高考试卷中阅读理解题中相对比较难的，通常后置。

说明文的词汇和句式的运用较别的体裁的文章难度更大。

词汇运用灵活，同一词的不同词性的用法交替出现，未列入考纲的生词较多，通常达到了4-5%。

不过考生可以通过说明文的语言特点来帮助理解语篇，例如，下定义、解释、举例、同义词、反义词、上下义词以及标点符号（如破折号、冒号都有表示解释和说明）等。

【满分技巧】高考阅读理解中，说明文为主要体裁之一。

高考阅读理解题的设问主要围绕以下四方面：细节事实题、主旨大意题、推理判断题、猜测词义题。

其中，说明文主要以细节事实、主旨大意和猜测词义三方面问题为主。

一、词义猜测类题型阅读理解题中常要求学生猜测某些单词或短语的意思。

词义的猜测还是贯穿在文章的阅读理解之中。

解这类题目一般是通过上下文去理解或根据构词法去猜测。

判断一个单词的意思不但离不开句子，而且还需要把句子放在上下文中，根据上下文提供的线索加以猜测。

运用构词法,语境等推测关键词义，可以根据以下几种方法猜测：（一）内在逻辑关系根据内在逻辑关系推测词义是指运用语言知识分析和判断相关信息之间存在的逻辑关系，然后根据逻辑关系推断生词词义。

1.通过同义词和反义词的关系猜词2.根据因果关系猜测词义3.通过定义或释义关系来推测词义4.通过句法功能来推测词义5.通过描述猜词（二）外部相关因素外部相关因素是指篇章（句子或段落）以外的其他知识，有时仅靠分析篇章内在逻辑关系无法猜出词义。

这时，就需要运用生活经验和普通常识确定词义。

例如：The snakes lithered through the grass.根据有关蛇的生活习性的知识，我们可以推断出slither词义为＂爬行＂。
