But that wasn't the most extraordinary thing. The most extraordinary thing was that the Lake Shore Drive Bridge is a drawbridge.“The first time, it was scary," Dorsay told a reporter from the Chicago Sun-Times, recalling how a bell would ring and his home would tip into the air, allowing ships to pass along the Chicago River below. "After that, it was almost like riding a ferry's wheel." Brian Steele, a spokesman for the Chicago Department of Transportation, puts it more straightforwardly. "Essentially," he says, "it changed his living space from horizontal(水平的) to vertical. "Dorsay had a history of homelessness and emotional problem. but inthe bridge. he thought, he had finally found a kind of stability. "You've got to be kind of agile(敏捷的)," he admitted. "But it doesn't take genius to figure out what to do. " Dorsay is now without a home, though he is currently staying with his parents. Gary, his father, said,"I've always hoped that he would find a place and he would seek employment. He is strong enough and bright enough to do something."(B) 24. According to Richard Dorsay, why did he like living in the bridge?A. It was free.B. He felt more secure there.C. It was an extraordinary thing.D. He liked scary things.推理题。

近三年（2020——2022）高考真题——说明文阅读2020年说明文阅读真题：1.（2020年新课标Ⅰ）CRace walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.28. Why are race walkers conditioned athletes?A. They must run long distances.B. They are qualified for the marathon.C. They have to follow special rules.D. They are good at swinging their legs.29. What advantage does race walking have over running?A. It’s more popular at the Olympics.B. It’s less challenging physically.C. It’s more effective in body building.D. It’s less likely to cause knee injuries.30. What is Dr. Norberg’s suggestion for someone trying race walking?A. Getting experts’ opinions.B. Having a medical checkup.C. Hiring an experienced coach.D. Doing regular exercises.31. Which word best describes the author’s attitude to race walking?A. Skeptical.B. Objective.C. Tolerant.D. Conservative.2.（2020年新课标Ⅰ）DThe connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.The engineers at the Massachusetts Institute of Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when they’reshort of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.One of his latest projects has been to make plants grow(发光)in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn tree into self-powered street lamps.in the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)-such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission(传输).Glowing plants could reduce this distance and therefore help save energy.32. What is the first paragraph mainly about?A. A new study of different plants.B. A big fall in crime rates.C. Employees from various workplaces.D. Benefits from green plants.33. What is the function of the sensors printed on plant leaves by MIT engineer?A. To detect plants’ lack of waterB. To change compositions of plantsC. To make the life of plants longer.D. To test chemicals in plants.34. What can we expect of the glowing plants in the future?A. They will speed up energy production.B. They may transmit electricity to the home.C. They might help reduce energy consumption.D. They could take the place of power plants.35. Which of the following can be the best title for the text?A. Can we grow more glowing plants?B. How do we live with glowing plants?C. Could glowing plants replace lamps?D. How are glowing plants made pollution-free?3.（2020年新课标Ⅰ）CWhen you were trying to figure out what to buy for the environmentalist on your holiday list, fur probably didn’t cross your mind. But some ecologists and fashion (时装)enthusiasts are trying to bring back the market for fur made from nutria(海狸鼠).Unusual fashion shows in New Orleans and Brooklyn have showcased nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt-free fur unless you understand that the nutria are destroying vast wetlands every year”, says Cree McCree, project director of Righteous Fur.Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month.Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non-native species(物种).It’s destroying the environment. It’s them or us.” says Michael Massimi, an expert in this field.The fur trade kept nutria check for decades，but when the market for nutria collapsed in the late 1980s，the cat-sized animals multiplied like crazy.Biologist Edmond Mouton runs the nutria control program for Louisiana. He says it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur.Then there’s Righteous Fur and its unusual fashion. Morgan says，”To give people a guilt-free option that they can wear without someone throwing paint on them---I think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable. She trying to come up with a label to attach to nutria fashions to show it is eco-friendly.28. What is the purpose of the fashion shows in New Orleans and Brooklyn?A. To promote guilt-free fur.B. To expand the fashion market.C. To introduce a new brand.D. To celebrate a winter holiday.29. Why are scientists concerned about nutria?A. Nutria damage the ecosystem seriously.B. Nutria are an endangered species.C. Nutria hurt local cat-sized animals.D. Nutria are illegally hunted.30. What does the underlined word “collapsed” in paragraph 5 probably mean?A. Boomed.B. Became mature.C. Remained stable.D. Crashed.31. What can we infer about wearing fur in New York according to Morgan?A. It’s formal.B. It’s risky.C. It’s harmful.D. It’s traditional.4.（2020年新课标Ⅰ）DWe 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.Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they could stay underwater much longer than us local islanders,” Dr. Jubilado said. “I could see them actually walking under the sea.”In2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. “it seemed like the perfect chance for natural selection to act on a population,” said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.32. What does the author want to tell us by the examples in paragraph 1?A. Environmental adaptation of cattle raisers.B. New knowledge of human evolution.C. Recent findings of human origin.D. Significance of food selection.33. Where do the Bajau build their houses?A. In valleys.B. Near riversC. On the beach.D. Off the coast.34. Why was the young Jubilado astonished at the Bajau?A. They could walk on stilts all day.B. They had a superb way of fishing.C. They could stay long underwater.D. They lived on both land and water.35. What can be a suitable title for the text?A. Bodies Remodeled for a Life at SeaB. Highlanders’ Survival SkillsC. Basic Methods of Genetic ResearchD. The World’s Best Divers2021年说明文阅读真题：1.（2021新高考I卷C）When the explorers first set foot upon the continent of North America, the skies and lands were alive with an astonishing variety of wildlife. Native Americans had taken care of these precious natural resources wisely. Unfortunately, it took the explorers and the settlers who followed only a few decades to decimate a large part of these resources. Millions of waterfowl (水禽) were killed at the hands of market hunters and a handful of overly ambitious sportsmen. Millions of acres of wetlands were dried to feed and house the ever-increasing populations, greatly reducing waterfowl habitat (栖息地).In 1934, with the passage of the Migratory Bird Hunting Stamp Act (Act), an increasingly concerned nation took firm action to stop the destruction of migratory (迁徙的) waterfowl and the wetlands so vital to their survival. Under this Act, all waterfowl hunters 16 years of age and over must annually purchase and carry a Federal Duck Stamp. The very first Federal Duck Stamp was designed by J.N. “Ding” Darling, a political ca rtoonist from Des Moines, lowa, who at that time was appointed by President Franklin Roosevelt as Director of the Bureau of Biological Survey. Hunters willingly pay the stamp price to ensure the survival of our natural resources.About 98 cents of every duck stamp dollar goes directly into the Migratory Bird Conservation Fund to purchase wetlands and wildlife habitat for inclusion into the National Wildlife Refuge System —a fact that ensures this land will be protected and available for all generations to come. Since 1934, better than half a billion dollars has gone into that Fund to purchase more than 5 million acres of habitat. Little wonder the Federal Duck Stamp Program has been called one of the most successful conservation programs ever initiated.28. What was a cause of the waterfowl population decline in North America?A. Loss of wetlands.B. Popularity of water sports.C. Pollution of rivers.D. Arrival of other wild animals.29. What does the underlined word “decimate” mean in the first paragraph?A. Acquire.B. Export.C. Destroy.D. Distribute.30. What is a direct result of the Act passed in 1934?A. The stamp price has gone down.B. The migratory birds have flown away.C. The hunters have stopped hunting.D. The government has collected money.31. Which of the following is a suitable title for the text?A. The Federal Duck Stamp StoryB. The National Wildlife Refuge SystemC. The Benefits of Saving WaterfowlD. The History of Migratory Bird Hunting2.（2021新高考II卷D）An Australian professor is developing a robot to monitor the health of grazing cattle, a development that could bring big changes to a profession that's relied largely on a low-tech approach for decades but is facing a labor shortage.Salah Sukkarieh, a professor at the University of Sydney, sees robots as necessary given how cattlemen are aging. He is building a four-wheeled robot that will run on solar and electric power. It will use cameras and sensors to monitor the animals. A computer system will analyze the video to determine whether a cow is sick. Radio tags (标签) on the animals will measure temperature changes. The quality of grassland will be tracked by monitoring the shape, color and texture (质地) of grass. That way, cattlemen will know whether they need to move their cattle to another field for nutrition purposes.Machines have largely taken over planting, watering and harvesting crops such as corn and wheat, but the monitoring of cattle has gone through fewer changes.For Texas cattleman Pete Bonds, it's increasingly difficult to find workers interested in watching cattle. But Bonds doesn't believe a robot is right for the job. Years of experience in the industry—and failed attempts to use technology—have convinced him that the best way to check cattle is with a man on a horse. Bonds, who bought his first cattle almost 50 years ago, still has each of his cowboys inspect 300 or 400 cattle daily and look for signs that an animal is getting sick.Other cattlemen see more promise in robots. Michael Kelsey, vice president of the Oklahoma Cattlemen's Association, said a robot could be extremely useful given rising concerns about cattle theft. Cattle tend to be kept in remote places and their value has risen, making them appealing targets.32. What is a problem with the cattle-raising industry?A. Soil pollution.B. Lack of workers.C. Aging machines.D. Low profitability.33. What will Sukkarieh's robot be able to do?A. Monitor the quality of grass.B. Cure the diseased cattle.C. Move cattle to another field.D. Predict weather changes.34. Why does Pete Bonds still hire cowboys to watch cattle?A. He wants to help them earn a living.B. He thinks men can do the job better.C. He is inexperienced in using robots.D. He enjoys the traditional way of life.35. How may robots help with cattle watching according to Michael Kelsey?A. Increase the value of cattle.B. Bring down the cost of labor.C. Make the job more appealing.D. Keep cattle from being stolen.3.（2021全国乙卷D）During an interview for one of my books, my interviewer said something I still think about often. Annoyed by the level of distraction (干扰) in his open office, he said, “That’s why I have a membership at the coworking space across the street—so I can focus.” His comment struck me as strange. After all, coworking spaces also typically use an open office layout (布局). But I recently came across a study that shows why his approach works.The researchers examined various levels of noise on participants as they completed tests of creative thinking. They were randomly divided into four groups and exposed to various noise levels in the background, from total silence to 50 decibels (分贝), 70 decibels, and 85 decibels. The differences between most of the groups were statistically insignificant; however, theparticipants in the 70 decibels group—those exposed to a level of noise similar to background chatter in a coffee shop—significantly outperformed the other groups. Since the effects were small, this may suggest that our creative thinking does not differ that much in response to total silence and 85 decibels of background noise.But since the results at 70 decibels were significant, the study also suggests that the right level of background noise—not too loud and not total silence—may actually improve one’s creative thinking ability. The right level of background noise may interrupt our normal patterns of thinking just enough to allow our imaginations to wander, without making it impossible to focus. This kind of “distracted focus” appears to be the best state for working on creative tasks.So why do so many of us hate our open offices? The problem may be that, in our offices, we can’t stop ourselves from getting drawn into others’ conversations while we’re trying to focus. Indeed, the researchers found that face-to-face interactions and conversations affect the creative process, and yet a coworking space or a coffee shop provides a certain level of noise while also providing freedom from interruptions.32. Why does the interviewer prefer a coworking space?A. It helps him concentrateB. It blocks out background noiseC. It has a pleasant atmosphereD. It encourages face-to-face interactions33. Which level of background noise may promote creative thinking ability?A. Total silenceB. 50 decibelsC. 70 decibelsD. 85 decibels34. What makes an open office unwelcome to many people?A. Personal privacy unprotectedB. Limited working spaceC. Restrictions on group discussionD. Constant interruptions35.What can we infer about the author from the text?A. He’s a news reporter.B. He’s on office manager.C. He’s a professional designer.D. He’s a published writer.4.（2021天津卷C）In the fictional worlds of film and TV, artificial intelligence (AI) has been described as so advanced that it is indistinguishable from humans. But what if we're actually getting closer to a world where AI is capable of thinking and feeling?Tech company UneeQ is heading for its “digital humans”, which appear lifelike on the screen not only in terms of language, but also because of facial movements: raised eyebrows, a smile, even a nod. They look close to a human, but not quite.What lies beneath UneeQ’s digital humans? Their 3D faces are modeled on actual human features. Speech recognition enables them to understand what a person is saying, and natural language processing is used to work out a response. Meanwhile, another AI company, Soul Machines, is taking a more biological approach, with a “digital brain”, that imitates aspects of the human brain to adjust the emotions “felt” and “expressed” by its "digital people".Shiwali Mohan, an AI scientist at the Palo Research Center, is skeptical of these digital beings. “They're humanlike in their looks and the way they sound, but that in itself is not being human,” she says. “Human qualities also involve how you think, how you approach problems, and how you break them down; and that takes a lot of algorithmic (算法)design. Designing for human-level intelligence is a different attempt than designing images that behave like humans.”She then continues, “If something looks like a human, we have high expectations of them, but they might behave differently in ways that humans just instinctively (直觉地)know how other humansreact.”Yet the demand is there, with UneeQ seeing high adoption of its digital employees across the financial, health care, and commercial sectors （行业）. “ Unless these sectors make their business models much more efficient digitally, they might be left behind,” says Chetan Dube, UneeQ’s CEO.Some other companies are taking their digital beings a step further, enabling organizations and individuals to create digital humans themselves using free-access platforms they provide. “The biggest motivation for such platforms is to popularize AI,” Dube says.Mohan is cautious about this approach, yet she supports the purpose behind these digital beings and is optimistic about where they are headed. “As we develop more advanced AI technology, we would then have to use new ways of communicating with that technology,”she says. “'Hopefully, all of that is designed to support humans in their goals.”46. According to Para. 2, in what respect(s) do UneeQ’s "digital humans" resemble human beings?A. In the way they move around.B. In the way they act and react.C. In observation and analysis.D. In speech and facial expressions.47. Soul Machines’ digital brain is a technological breakthrough because it___________.A. learns to make proper emotional responsesB. tends to imitate human beings' tone vividlyC. recognizes the speech sounds it receivesD. processes the natural language it hears48. In Mohan’s opinion, what human quality is lacking in digital beings?A. Calculating brain.B. Language skills.C. Instinctive judgements.D. Problem-solving ability.49. What makes many sectors employ digital humans?A. The fear of falling behind in efficiency.B. The urgency to promote e-commerce.C. The wish to spread digital technology.D. The need to upgrade the health care system.50. What does Mohan think of the future of digital beings?A. It's well planned.B. It is promising.C. It is uncertain.D. It's quite hopeless.5.（2021浙江卷C）If you ever get the impression that your dog can “tell” whether you look content or annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human faces, according to a new study.Researchers trained a group of 11 dogs to distinguish between images (图像) of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person’s face. The researchers then tested the dogs’ ability to distinguish between human facial expressions by showing them the other half of the person’s face or images totally different from the ones used in training. The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.The study showed the animals had figured out how to apply what they learned about human faces during training to new faces in the testing stage. “We can rule out that the dogs simply distinguish between the pictures based on a simple cue, such as the sight of teeth,” said study author Corsin Müller. “Instead, our results suggest that the successful dogs realized that a smiling mouth means the same thing as smiling eyes, and the same rule applies to an angry mouth havingthe same meaning as angry eyes.”“With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions,” Müller told Live Science.At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial expressions in humans. “To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions, and this exposure has provided them with many chances to learn to distinguish between them,” Müller said.28. The new study focused on whether dogs can _________.A. distinguish shapesB. make sense of human facesC. feel happy or angryD. communicate with each other29. What can we learn about the study from paragraph 2?A. Researchers tested the dogs in random order.B. Diverse methods were adopted during training.C. Pictures used in the two stages were different.D. The dogs were photographed before the test.30. What is the last paragraph mainly about?A. A suggestion for future studies.B. A possible reason for the study findings.C. A major limitation of the study.D. An explanation of the research method.6.（2021北京卷C）Hundreds of scientists, writers and academics sounded a warning to humanity in an open letter published last December：Policymakers and the rest of us must engage openly with the risk of global collapse. Researchers in many areas have projected the widespread collapse as “a credible scenario（情景）this century”．A survey of scientists found that extreme weather events，food insecurity，and freshwater shortages might create global collapse．Of course，if you are a non-human species，collapse is well underway．The call for public engagement with the unthinkable is especially germane in this moment of still-uncontrolled pandemic and economic crises in the world's most technologically advanced nations．Not very long ago，it was also unthinkable that a virus would shut down nations and that safety nets would be proven so disastrously lacking in flexibility．The international scholars' warning letter doesn't say exactly what collapse will look like or when it might happen．Collapseology，the study of collapse，is more concerned with identifying trends and with them the dangers of everyday civilization．Among the signatories（签署者）of the warning was Bob Johnson，the originator of the“ecological footprint”concept，which measures the total amount of environmental input needed to maintain a given lifestyle．With the current footprint of humanity，“it seems that global collapse is certain to happen in some form，possibly within a decade，certainly within this century，”Johnson said in an email．Only if we discuss the consequences of our biophysical limits, the December warning letter says，can we have the hope to reduce their “speed，severity and harm”．And yet messengers of the coming disturbance are likely to be ignored．We all want to hope things will turn out fine．As a poet wrote，Man is a victim of dope（麻醉品）In the incurable form of hope．The hundreds of scholars who signed the letter are intent（执着）on quieting hope that ignores preparedness．“Let's look directly into the issue of collapse，”hey say，“and deal with the terrible possibilities of what we see there to make the best of a troubling future．”28. What does the underlined word“germane”in Paragraph 3 probably mean?A. Scientific．B. Credible．C. Original．D. Relevant．29. As for the public awareness of global collapse，the author is__________．A. worriedB. puzzledC. surprisedD. scared30. What can we learn from this passage?A. The signatories may change the biophysical limits．B. The author agrees with the message of the poem．C. The issue of collapse is being prioritized．D. The global collapse is well underway．2022年说明文阅读真题：1. (2022年全国高考新高考II卷C)Over the last seven years, most states have banned texting by drivers, and public service campaigns have tried a wide range of methods to persuade people to put down their phones when they are behind the wheel.Yet the problem, by just about any measure, appears to be getting worse. Americans are still texting while driving, as well as using social networks and taking photos. Road accidents, which had fallen for years, are now rising sharply.That is partly because people are driving more, but Mark Rosekind, the chief of the National Highway Traffic Safety Administration, said distracted（分心）driving was "only increasing, unfortunately. ""Big change requires big ideas. " he said in a speech last month, referring broadly to the need to improve road safety. So to try to change a distinctly modern behavior, lawmakers and public health experts are reaching back to an old approach: They want to treat distracted driving like drunk driving.An idea from lawmakers in New York is to give police officers a new device called the Textalyzer. It would work like this: An officer arriving at the scene of a crash could ask for the phones of the drivers and use the Textalyzer to check in the operating system for recent activity. The technology could determine whether a driver had just texted, emailed or done anything else that is not allowed under New York's hands-free driving laws."We need something on the books that can change people's behavior,” said Félix W. Ortiz, who pushed for the state's 2001 ban on hand-held devices by drivers. If the Textalyzer bill becomes law, he said, "people are going to be more afraid to put their hands on the cell phone. "8. Which of the following best describes the ban on drivers' texting in the US?A. Ineffective.B. Unnecessary.C. Inconsistent.D. Unfair.9. What can the Textalyzer help a police officer find out?A. Where a driver came from.B. Whether a driver used their phone.C. How fast a driver was going.D. When a driver arrived at the scene.10. What does the underlined word "something" in the last paragraph refer to?A. Advice.B. Data.C. Tests.D. Laws.11. What is a suitable title for the text?。

历年高考英语真题分类汇编之阅读理解科技说明文(含答案)

历年高考英语真题分类汇编之阅读理解科技说明文（2023年1月浙江卷）CA machine can now not only beat you at chess, it can also outperform you in debate. Last week, in a public debate in San Francisco, a software program called Project Debater beat its human opponents, including Noa Ovadia, Israel's former national debating champion.Brilliant though it is, Project Debater has some weaknesses. It takes sentences from its library of documents and prebuilt arguments and strings them together. This can lead to the kinds of errors no human would make. Such wrinkles will no doubt be ironed out, yet they also point to a fundamental problem. As Kristian Hammond, professor of electrical engineering and computer science at Northwestern University, put it: “There's never a stage at which the sys tem knows what it's talking about.”What Hammond is referring to is the question of meaning, and meaning is central to what distinguishes the least intelligent of humans from the most intelligent of machines. A computer works with symbols. Its program specifies a set of rules to transform one string of symbols into another. But it does not specify what those symbols mean. Indeed, to a computer, meaning is irrelevant. Humans, in thinking, talking, reading and writing, also work with symbols. But for humans, meaning is everything. When we communicate, we communicate meaning. What matters is not just the outside of a string of symbols, but the inside too, not just how they are arranged but what they mean.Meaning emerges through a process of social interaction, not of computation, interaction that shapes the content of the symbols in our heads. The rules that assign meaning lie not just inside our heads, but also outside, in society, in social memory, social conventions and social relations. It is this that distinguishes humans from machines. And that's why, however astonishing Project Debater may seem, the tradition that began with Socrates and Confucius will not end with artificial intelligence.28.Why does the author mention Noa Ovadia in the first paragraph?A.To explain the use of a software program.B.To show the cleverness of Project Debater.C.To introduce the designer of Project Debater.D.To emphasize the fairness of the competition.29.What does the underlined word “wrinkles” in paragraph 2 refer to?A. Arguments.B. Doubts.C. Errors.D. Differences.30.What is Project Debater unable to do according to Hammond?A. Create rules.B. Comprehend meaning.C. Talk fluently.D. Identify difficult words.31.What can we learn from the last paragraph?A.Social interaction is key to understanding symbols.B.The human brain has potential yet to be developed.C.Ancient philosophers set good examples for debaters.D.Artificial intelligence ensures humans a bright future.（2023年1月浙江卷）DAccording to the Solar Energy Industry Association, the number of solar panels installed ( 安装) has grown rapidly in the past decade, and it has to grow even faster to meet climate goals. But all of that growth will take up a lot of space, and though more and more people accept the concept of solar energy, few like large solar panels to be installed near them.Solar developers want to put up panels as quickly and cheaply as possible, so they haven't given much thought to what they put under them. Often, they'll end up filling the area with small stones and using chemicals to control weeds. The result is that many communities, especially in farming regions, see solar farms as destroyers of the soil.“Solar projects need to be good neighbors,” says Jordan Mackn ick, the head of the Innovative Site Preparation and Impact Reductions on the Environment(InSPIRE) project. “They need to be protectors of the land and contribute to the agricultural economy.” InSPIRE is investigating practical approaches to “low-impact” s olar development, which focuses on establishing and operating solar farms in a way that is kinder to the land. One of the easiest low-impact solar strategies is providing habitat for pollinators(传粉昆虫).Habitat loss, pesticide use, and climate change have caused dramatic declines in pollinator populations over the past couple of decades, which has damaged the U.S. agricultural economy. Over 28 states have passed laws related to pollinator habitat protection and pesticide use. Conservation organizations put out pollinator-friendliness guidelines for home garde ns, businesses, schools, cities—and now there are guidelines for solar farms.Over the past few years, many solar farm developers have transformed the space under their solar panels into a shelter for various kinds of pollinators, resulting in soilimprovement and carbon reduction. “These pollinator-friendly solar farms can have a valuable impact on everything that's going on in the landscape,” says Macknick.32.What do solar developers often ignore?A.The decline in the demand for solar energy.B.The negative impact of installing solar panels.C.The rising labor cost of building solar farms.D.The most recent advances in solar technology.33.What does InSPIRE aim to do?A.Improve the productivity of local farms.B.Invent new methods for controlling weeds.C.Make solar projects environmentally friendly.D.Promote the use of solar energy in rural areas.34.What is the purpose of the laws mentioned in paragraph 4?A. To conserve pollinators.B. To restrict solar development.C. To diversify the economy.D. To ensure the supply of energy.35.Which of the following is the best title for the text?A. Pollinators: To Leave or to StayB. Solar Energy: Hope for the FutureC. InSPIRE: A Leader in AgricultureD. Solar Farms: A New Development(2022年全国乙卷）CCan a small group of drones(无人机)guarantee the safety and reliability of railways and, at the same time, help railway operators save billions of euros each year? That is the very likely future of applying today’s eyes in the sky technology to making sure that the millions of kilometres of rail tracks and infrastructure(基础设施)worldwide are safe for trains on a 24/7 basis.Drones are already being used to examine high-tension electrical lines. They could do precisely the same thing to inspect railway lines and other vital aspects of rail infrastructure such as the correct position of railway tracks and switching points. The more regularly they can be inspected, the more railway safety, reliability and on-time performance will be improved. Costs would be cut and operations would be more efficient(高效)across the board.That includes huge savings in maintenance costs and better protection of railway personnel safety. It is calculated that European railways alone spend approximately 20 billion euros a year on maintenance, including sending maintenance staff, often at night, to inspect and repair the rail infrastructure. That can be dangerous work that could be avoided with drones assisting the crews efforts.By using the latest technologies, drones could also start providing higher-valueservices for railways, detecting faults in the rail or switches, before they can cause any safety problems. To perform these tasks, drones for rail don’t need to be flying overhead. Engineers are now working on a new concept: the rail drones of the future. They will be moving on the track ahead of the train, and programmed to run autonomously. Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot. With their ability to see ahead, they could signal any problem, so that fast-moving trains would be able to react in time.28. What makes the application of drones to rail lines possible?A. The use of drones in checking on power lines.B.Drones ability to work at high altitudes.C. The reduction of cost in designing drones.D. Drones reliable performance in remote areas.29. What does maintenance underlined in paragraph 3 refer to?A. Personnel safety.B. Assistance from drones.C. Inspection and repair.D. Construction of infrastructure.30. What function is expected of the rail drones?A. To provide early warning.B. To make trains run automatically.C. To earn profits for the crews.D. To accelerate transportation.31. Which is the most suitable title for the text?A. What Faults Can Be Detected with DronesB. How Production of Drones Can Be ExpandedC. What Difficulty Drone Development Will FaceD. How Drones Will Change the Future of Railways（2022年全国Ⅰ卷）DHuman speech contains more than 2,000 different sounds, from the common “m” and “a” to the rare clicks of some southern African languages. But why are certain sounds more common than others? A ground-breaking, five-year study shows that diet-related changes in human bite led to new speech sounds that are now found in half the world's languages.More than 30 years ago, the scholar Charles Hockett noted that speech sounds called labiodentals, such as “f” and “v", were more common in the languages of societies that ate softer foods. Now a team of researchers led by Damián Blasi at the University of Zurich, Switzerland, has found how and why this trend arose.They discovered that the upper and lower front teeth of ancient human adults were aligned (对齐), making it hard to produce labiodentals, which are formed by touchingthe lower lip to the upper teeth. Later, our jaws changed to an overbite structure (结构), making it easier to produce such sounds.The team showed that this change in bite was connected with the development of agriculture in the Neolithic period. Food became easier to chew at this point. The jawbone didn't have to do as much work and so didn't grow to be so large.Analyses of a language database also confirmed that there was a global change in the sound of world languages after the Neolithic age, with the use of “f” and "v" increasing remarkably during the last few thousand years. These sounds are still not found in the languages of many hunter-gatherer people today.This research overturns the popular view that all human speech sounds were present when human beings evolved around 300,000 years ago. "The set of speech sounds we use has not necessarily remained stable since the appearance of human beings, but rather the huge variety of speech sounds that we find today is the product of a complex interplay of things like biological change and cultural evolution," said Steven Moran, a member of the research team.32. Which aspect of the human speech sound does Damián Blasi's research focus on?A. Its variety.B. Its distribution.C. Its quantity.D. Its development.33. Why was it difficult for ancient human adults to produce labiodentals?A. They had fewer upper teeth than lower teeth.B. They could not open and close their lips easily.C. Their jaws were not conveniently structured.D. Their lower front teeth were not large enough.34. What is paragraph 5 mainly about?A. Supporting evidence for the research results.B. Potential application of the research findings.C. A further explanation of the research methods.D. A reasonable doubt about the research process.35. What does Steven Moran say about the set of human speech sounds?A. It is key to effective communication.B. It contributes much to cultural diversity.C. It is a complex and dynamic system.D. It drives the evolution of human beings.（2022年全国Ⅱ卷）DAs we age, even if we're healthy, the heart just isn't as efficient in processing oxygen as it used to be. In most people the first signs show up in their 50s or early60s. And among people who don't exercise, the changes can start even sooner."Think of a rubber band. In the beginning, it is flexible, but put it in a drawer for 20 years and it will become dry and easily broken," says Dr. Ben Levine, a heart specialist at the University of Texas. That's what happens to the heart. Fortunately for those in midlife, Levine is finding that even if you haven't been an enthusiastic exerciser, getting in shape now may help improve your aging heart.Levine and his research team selected volunteers aged between 45 and 64 who did not exercise much but were otherwise healthy. Participants were randomly divided into two groups. The first group participated in a program of non aerobic（无氧）exercise—balance training and weight training—three times a week. The second group did high-intensity aerobic exercise under the guidance of a trainer for four or more days a week.After two years, the second group saw remarkable improvements in heart health."We took these 50-year-old hearts and turned the clock back to 30-or 35-year-old hearts," says Levine. "And the reason they got so much stronger and fitter was that their hearts could now fill a lot better and pump（泵送）a lot more blood during exercise." But the hearts of those who participated in less intense exercise didn't change, he says."The sweet spot in life to start exercising, if you haven't already, is in late middle age when the heart still has flexibility," Levine says. "We put healthy 70-year-olds through a yearlong exercise training program, and nothing happened to them at all."Dr. Nieca Goldberg, a spokeswoman for the American Heart Association, says Levine's findings are a great start. But the study was small and needs to be repeated with far larger groups of people to determine exactly which aspects of an exercise routine make the biggest difference.32. What does Levine want to explain by mentioning the rubber band?A. The right way of exercising.B. The causes of a heart attack.C. The difficulty of keeping fit.D. The aging process of the heart.33. In which aspect were the two groups different in terms of research design?A. Diet plan.B. Professional background.C. Exercise type.D. Previous physical condition.34. What does Levine's research find?A. Middle-aged hearts get younger with aerobic exercise.B. High-intensity exercise is more suitable for the young.C. It is never too late for people to start taking exercise.D. The more exercise we do, the stronger our hearts get.35. What does Dr. Nieca Goldberg suggest?A. Making use of the findings.B. Interviewing the study participants.C. Conducting further research.D. Clarifying the purpose of the study.（2022年北京卷）DQuantum ( 量子 ) computers have been on my mind a lot lately. A friend has been sending me articles on how quantum computers might help solve some of the biggest challenges we face as humans. I’ve also had exchanges with two quantum-computing experts. One is computer scientist Chris Johnson who I see as someone who helps keep the field honest. The other is physicist Philip Taylor.For decades, quantum computing has been little more than a laboratory curiosity. Now, big tech companies have invested in quantum computing, as have many smaller ones. According to Business Weekly, quantum machines could help us “cure cancer, and even take steps to turn climate change in the opposite direction.” This is the sort of hype (炒作 ) that annoys Johnson. He worries that researchers are making promises they can’t keep. “What’s new,” Johnson wrote, “is that millions of do llars are now potentially available to quantum computing researchers.”As quantum computing attracts more attention and funding, researchers may mislead investors, journalists, the public and, worst of all, themselves about their work’s potential. If researchers can’t keep their promises, excitement might give way to doubt, disappointment and anger, Johnson warns. Lots of other technologies have gone through stages of excitement. But something about quantum computing makes it especially prone to hype, Johnson suggests, perhaps because “‘quantum’ stands for something cool you shouldn’t be able to understand.” And that brings me back to Taylor, who suggested that I read his book Q for Quantum.After I read the book, Taylor patiently answered my questions about it. He also answered my questions about PyQuantum, the firm he co-founded in 2016. Taylor shares Johnson’s concerns about hype, but he says those concerns do not apply to PyQuantum.The company, he says, is closer than any other firm “by a very large margin ( 幅度)” to building a “useful” quantum computer, one that “solves an impactful problem that we would not have been able to solve otherwise.” He adds, “People will naturally discount my opinions, but I have spent a lot of time quantitatively comparin g what we are doing with others.”Could PyQuantum really be leading all the competition “by a wide margin”, as Taylor claims? I don’t know. I’m certainly not going to advise my friend oranyone else to invest in quantum computers. But I trust Taylor, just as I trust Johnson.31. Regarding Johnson’s concerns, the author feels ________.A.sympatheticB.unconcernedC.doubtfulD.excited32. What leads to Taylor’s optimism about quantum computing?A.His dominance in physics.B.The competition in the field.C.His confidence in PyQuantum.D. The investment of tech companies.33. What does the underlined word “prone” in Paragraph 3 most probably mean?A.Open.B.Cool.eful.D.Resistant.34. Which would be the best title for the passage?A. Is Johnson More Competent Than Taylor?B. Is Quantum Computing Redefining Technology?C. Will Quantum Computers Ever Come into Being?D. Will Quantum Computing Ever Live Up to Its Hype?（2022年浙江卷）BAll around the world, there are small changes taking place. At the side of roads, behind school playgrounds and on all kinds of unloved pieces of land across towns and cities, tiny forests barely the size of tennis courts are appearing, making a great place for both wildlife and local people who may not normally have easy access to nature. This is the Tiny Forest movement, which aims to prove that the best things in life really do come in small packages.Tiny forests were first pioneered as a concept in the 1970s by Dr Miyawaki, a Japanese botanist. As he went on to share his concept with others, the idea soon took off in India and other countries before eventually reaching Europe, where it became popular in places like France, Belgium and the Netherlands.So how does it work? Louise Hartley, who is leading the Tiny Forest project in the UK, explains that the process begins by identifying areas in which a tiny forest could have the biggest influence. “We focus on urban areas where access to natur e is often not that easy,” says Hartley. “We see it as a chance to try to break the growing disconnect between people and nature.”In a Tiny Forest, there must be a minimum of 600 trees, and the trees are planted much closer together and without chemicals or fertilisers (肥料). There are usually around 30 different kinds of all-native tree species (物种). This variety, coupled with the fact that tiny forests grow up to ten times faster than standard forests, means they attract a rich abundance of wildlife. It’s also thought that these places could help reduce the risk of flooding, remove carbon from theatmosphere and fight climate change, as well as improving the mental health of those living locally.24. What do we know about the Tiny Forest movement?A. It has achieved notable success.B. It is led by a number of schools.C. It began in Europe in the 1970s.D. It will spread to the countryside.25. What is the purpose of the project led by Hartley in the UK?A. To promote eco-tourism.B. To improve forestry research.C. To popularise gardening.D. To get people close to nature.26. What is special about the trees in a Tiny Forest?A. They are small in size.B. They are thickly planted.C. They are foreign species.D. They are heavily fertilised.（2021年全国Ⅱ卷）DAn Australian professor is developing a robot to monitor the health of grazing cattle, a development that could bring big changes to a profession that's relied largely on a low-tech approach for decades but is facing a labor shortage.Salah Sukkarieh, a professor at the University of Sydney, sees robots as necessary given how cattlemen are aging. He is building a four-wheeled robot that will run on solar and electric power. It will use cameras and sensors to monitor the animals. A computer system will analyze the video to determine whether a cow is sick. Radio tags （标签）on the animals will measure temperature changes. The quality of grassland will be tracked by monitoring the shape，color and texture （质地）of grass. That way，cattlemen will know whether they need to move their cattle to another field for nutrition purposes.Machines have largely taken over planting, watering and harvesting crops such as com and wheat, but the monitoring of cattle has gone through fewer changes.For Texas cattleman Pete Bonds, it's increasingly difficult to find workers interested in watching cattle. But Bonds doesn't believe a robot is right for the job. Years of experience in the industry - and failed attempts to use technology - have convinced him that the best way to check cattle is with a man on a horse. Bonds, who bought his first cattle almost 50 years ago, still has each of his cowboys inspect 300 or 400 cattle daily and look for signs that an animal is getting sick.Other cattlemen see more promise in robots. Michael Kelsey Paris, vice president of the Oklahoma Cattlemen's Association, said a robot could be extremely useful given rising concems about cattle theft. Cattle tend to be kept in remote places and their valuehas risen, making them appealing targets.32.What is a problem with the cattle-raising industry?A. Soil pollution.ck of workers.C.Aging machines.D. Low profitability.33. What will Sukkarieh's robot be able to do?A.Monitor the quality of grass.B.Cure the diseased cattle.C.Move cattle to another field.D.Predict weather changes.34.Why does Pete Bonds still hire cowboys to watch cattle?A. He wants to help them earn a living.B.He thinks men can do the job better.C. He is inexperienced in using robots.D.He enjoys the traditional way of life.35.How may robots help with cattle watching according to Michael Kelsey?A.Increase the value of cattle.B. Bring down the cost of labor.C.Make the job more appealing.D.Keep cattle from being stolen.（2021年全国乙卷）You've heard that plastic is polluting the oceans — between 4.8 and 12.7 million tonnes enter ocean ecosystems every year. But does one plastic straw or cup really make a difference? Artist Benjamin V on Wong wants you to know that it does. He builds massive sculptures out of plastic garbage, forcing viewers to re-examine their relationship to single-use plastic products.At the beginning of the year, the artist built a piece called “Strawpocalypse,” a pair of 10-foot-tall plastic waves, frozen mid-crash.Made of 168,000 plastic straws collected from several volunteer beach cleanups, the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City, Vietnam.Just 9% of global plastic waste is recycled. Plastic straws are by no means the biggest source（来源）of plastic pollution, but they've recently come under fire because most people don't need them to drink with and, because of their small size and weight, they cannot be recycled. Every straw that's part of V on Wong's artwork likely came from a drink that someone used for only a few minutes.Once the drink is gone, the straw will take centuries to disappear.In a piece from 2018, V on Wong wanted to illustrate（说明）a specific statistic: Every 60 seconds, a truckload's worth of plastic enters the ocean. For this work, titled “Truckload of Plastic,” V on Wong and a group of volunteers collected more than 10,000 pieces of plastic, which were then tied together to look like they'd been dumped（倾倒）from a truck all at once.V on Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.28.What are V on Wong's artworks intended for？______A.Beautifying the city he lives in.B.Introducing eco-friendly products.C.Drawing public attention to plastic waste.D.Reducing garbage on the beach.29. Why does the author discuss plastic straws in paragraph 3？______A.To show the difficulty of their recycling.B.To explain why they are useful.C.To voice his views on modern art.D.To find a substitute for them.30. What effect would "Truckload of Plastic" have on viewers？______A.Calming.B.Disturbing.C.Refreshing.D.Challenging.31. Which of the following can be the best title for the text？______A.Artists' Opinions on Plastic SafetyB.Media Interest in Contemporary ArtC.Responsibility Demanded of Big CompaniesD.Ocean Plastics Transformed into Sculptures（2020全国I卷）DThe connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.The engineers at the Massachusetts Institute of Technology（MIT）have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when they’re short of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.One of his latest projects has been to make plants grow（发光）in experiments using some common vegetables. Strano’s team f ound that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn tree into self-powered street lamps.in the future，the team hopes to develop a version of the technology that can besprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source（电源）—such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission（传输）.Glowing plants could reduce this distance and therefore help save energy.32. What is the first paragraph mainly about?A. A new study of different plants.B. A big fall in crime rates.C. Employees from various workplaces.D. Benefits from green plants.33. What is the function of the sensors printed on plant leaves by MIT engineer?A. To detect plants’ lack of waterB. To change compositions of plantsC. To make the life of plants longer.D. To test chemicals in plants.34. What can we expect of the glowing plants in the future?A. They will speed up energy production.B. They may transmit electricity to the home.C. They might help reduce energy consumption.D. They could take the place of power plants.35. Which of the following can be the best title for the text?A. Can we grow more glowing plants?B. How do we live with glowing plants?C. Could glowing plants replace lamps?D. How are glowing plants made pollution-free?（2020年全国II卷）BSome parents will buy any high-tech toy if they think it will help their child, but researchers said puzzles help children with math-related skills.Psychologist Susan Levine, an expert on mathematics development in young children the University of Chicago, found children who play with puzzles between ages 2 and 4later develop better spatial skills. Puzzle play was found to be a significant predictor of cognition(认知) after controlling for differences in parents’ income, education and the amount of parent talk, Levine said.。

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。

高考英语复习阅读理解专练说明文8篇Passage 1(2017北京,C)Measles(麻疹), which once killed 450 children each year and disabled even more, was nearly wiped out in the United States 14 years ago by the universal use of the MMR vaccine(疫苗). But the disease is making a comeback, caused by a growing anti-vaccine movement and misinformation that is spreading quickly. Already this year, 115 measles cases have been reported in the USA, compared with 189 for all of last year.The numbers might sound small, but they are the leading edge of a dangerous trend. When vaccination rates are very high, as they still are in the nation as a whole, everyone is protected. This is called“herd immunity”, which protects the people who get hurt easily, including those who can’t be vaccinated for medical reasons, babies too young to get vaccinated and people on whom the vaccine doesn’t work.But herd immunity works only when nearly the whole herd joins in. When some refuse vaccination and seek a free ride, immunity breaks down and everyone is in even bigger danger.That’s exactly what is happening in small neighborhoods around the country from Orange County, California, where 22 measles cases were reported this month, to Brooklyn, ., where a 17-year-old caused an outbreak last year.The resistance to vaccine has continued for decades, and it is driven by a real but very small risk. Those who refuse to take that risk selfishly make others suffer.>Making things worse are state laws that make it too easy to opt out(决定不参加)of what are supposed to be required vaccines for all children entering kindergarten. Seventeen states allow parents to get an exemption(豁免), sometimes just by signing a paper saying they personally object to a vaccine.Now, several states are moving to tighten laws by adding new regulations for opting out. But no one does enough to limit exemptions.Parents ought to be able to opt out only for limited medical or religious reasons. But personal opinionsNot good enough. Everyone enjoys the life-saving benefits vaccines provide, but they’ll exist only as long as everyone shares in the risks.first two paragraphs suggest that.small number of measles cases can start a dangerous trendoutbreak of measles attracts the public attentionmovement has its medical reasonsabout measles spreads quickly;immunity works well when.are allowedvaccines are used togetherwhole neighborhood is involved inregulations are added to the state lawsis the main reason for the comeback of measlesoveruse of vaccine.lack of medical care.?features of measles itself.vaccine opt-outs of some people.is the purpose of the passageintroduce the idea of exemption.discuss methods to cure measles.stress the importance of vaccination.appeal for equal rights in medical treatment.Passage 2(2017天津,A)}Suppose you’re in a rush, feeling tired, not paying attention to your screen, and you send an email that could get you in trouble.Realisation will probably set in seconds after you’ve clicked “send”.

But where are we doing all of this waiting, and what does it mean to an impatient society like oursTo understand the issue, let’s take a look at three types of “waits”.The very purest form of waiting is the Watched-Pot Wait. It is without doubt the most annoying of all. Take filling up the kitchen sink(洗碗池)as an example. There is absolutely nothing you can do while this is going on but keep both eyes fixed on the sink until it’s full. During these waits, the brain slips away from the body and wanders about until the water runs over the edge of the counter and onto your socks. This kind of wait makes the waiter helpless and mindless.,A cousin to the Watched-Pot Wait is the Forced Wait. This one requires a bit of discipline. Properly preparing packaged noodle soup requires a Forced Wait. Directions are very specific.“Bring three cups of water to boil, add mix, simmer three minutes, remove from heat, let standfive minutes.”I have my doubts that anyone has actually followed the procedures strictly. After all, Forced Waiting requires patience.Perhaps the most powerful type of waiting is the Lucky-Break Wait. This type of wait is unusual in that it is for the most part voluntary. Unlike the Forced Wait, which is also voluntary, waiting for your lucky break does not necessarily mean that it will happen.Turning one’s life into a waiting game requires faith and hope, and is strictly for the optimists among us. On the surface it seems as ridiculous as following the directions on soup mixes, but the Lucky-Break Wait well serves those who are willing to do it. As long as one doesn’t come to rely on it, wishing for a few good things to happen never hurts anybody.We certainly do spend a good deal of our time waiting. The next time you’re standing at the sink waiting for it to fill while cooking noodle soup that you’ll have to eat until a large bag of cash falls out of the sky, don’t be desperate. You’re probably just as busy as the next guy. doing a Watched-Pot Wait, we tend to.ourselves busy absent-mindedanxious focusedis the difference between the Forced Wait and the Watched-Pot Wait;Forced Wait requires some self-control.Forced Wait makes people passive.Watched-Pot Wait needs directions.Watched-Pot Wait engages body and brain.can we learn about the Lucky-Break Waitis less voluntary than the Forced Wait.doesn’t always bring the desired result.is more fruitful than the Forced Wait.）doesn’t give people faith and hope.does the author advise us to do the next time we are waitingit seriously.’t rely on others.something else.’t lose heart.author supports his view by.various causes of “waits”detailed processes of “waits”different categories of “waits”`frustrating consequences of “waits”Passage 4(2017浙江,B)Getting less sleep has become a bad habit for most American kids. According to a new survey(调查) by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.How much sleep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day!Adults need about eight hours. For most school-age children, ten hours is ideal(理想的). But the new National Sleep Foundation survey found that 35% of 10-to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtimeWatch TV.“More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone,”says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers’bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 am to 8:30 am. Students, parents and teachers are pleased with the results.is the new National Sleep Foundation survey onkids’sleeping habits.，’sleep-related diseases.to prevent sleeplessness.problems and lack of sleep.many hours of sleep do 11-year-olds need every dayhours.hours.hours.hours.do teenagers go to sleep late according to Carskadonare affected by certain body chemicals.￥tend to do things that excite them.follow their parents’examples.don’t need to go to school early.Passage 5(2017课标全国Ⅰ,C)Some of the world’s most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO(United Nations Educational, Scientific and Cultural Organization)recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(联合)voice across cultures.Despite the celebrations, though, in the . the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.It’s Jason Moran’s job to help change that. As the Kennedy Center’s artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.“Jazz seems like it’s not really a part of the American appetite,”Moran tells National Public Radio’s reporter Neal Conan.“What I’m hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and white anymore. It’s actually color, and it’s actually digital.”-Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost.“The music can’t be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same,”says Moran.Last year, Moran worked on a project that arranged Fats Waller’s music for a dance party,“just to kind of put it back in the mind that Waller is dance music as much as it is concert music,”says Moran.“For me, it’s the recontextualization. In music, where does the emotion(情感)lieAre we, as humans, gaining any insight(感悟)on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughtsSometimes we lose sight that the music has a wider context,”says Moran,“so I want to continue those dialogues. Those are the things I want to foster.”did UNESCO set April 30 as International Jazz Dayremember the birth of jazz.protect cultural diversity.encourage people to study music.recognize the value of jazz.does the underlined word“that”in paragraph 3 refer to`becoming more accessible.production of jazz growing faster.being less popular with the young.jazz audience becoming larger.can we infer about Moran’s opinion on jazzwill disappear gradually.remains black and white.should keep up with the times.#changes every 50 years.of the following can be the best title for the textthe Future of JazzRise and Fall of JazzStory of a Jazz Musicianthe Jazz DayPassage 6(2016课标Ⅲ,C)If you are a fruit grower—or would like to become one—take advantage of Apple Day to see what’s around. It’s called Apple Day but in practice it’s more like Apple Month. The day itself is on October 21, but since it has caught on, events now spread out over most of October around Britain.【Visiting an apple event is a good chance to see, and often taste, a wide variety of apples. To people who are used to the limited choice of apples such as Golden Delicious and Royal Gala in supermarkets, it can be quite an eye opener to see the range of classical apples still in existence, such as Decio which was grown by the Romans. Although it doesn’t taste of anything special, it’s still worth a try, as is the knobbly(多疙瘩的)Cat’s Head which is more of a curiosity than anything else.There are also varieties developed to suit specific local conditions. One of the very best varieties for eating quality is Orleans Reinette, but you’ll need a warm, sheltered place with perfect soil to grow it, so it’s a pipe dream for most apple lovers who fall for it.At the events, you can meet expert growers and discuss which ones will best suit your conditions, and because these are family affairs, children are well catered for with apple-themed fun and games.Apple Days are being held at all sorts of places with an interest in fruit, including stately gardens and commercial orchards(果园).

Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.The engineers at the Massachusetts Institute of Technology（MIT）have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show whe n they’re short of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.One of his latest projects has been to make plants grow（发光）in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn tree into self-powered street lamps.in the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source（电源）—such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission（传输）.Glowing plants could reduce this distance and therefore help save energy.32. What is the first paragraph mainly about?A. A new study of different plants.B. A big fall in crime rates.C. Employees from various workplaces.D. Benefits from green plants.33. What is the function of the sensors printed on plant leaves by MIT engineer?A. To detect plants’ lack of waterB. To change compositions of plantsC. To make the life of plants longer.D. To test chemicals in plants.34. What can we expect of the glowing plants in the future?A. They will speed up energy production.B. They may transmit electricity to the home.C. They might help reduce energy consumption.D. They could take the place of power plants.35. Which of the following can be the best title for the text?A. Can we grow more glowing plants?B. How do we live with glowing plants?C. Could glowing plants replace lamps?D. How are glowing plants made pollution-free?（2019全国卷I ）话题：利用生物信息进行身份识别CAs data and identity theft becomes more and more common, the market is growing for biometric（生物测量）technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.Researchers from Georgia Tech say that they have come up with a low-cost device（装置）that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence （节奏）with which one types and the pressure fingers apply to each key. The keyboard couldoffer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to —regardless of whether someone gets the password right.It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.In a study describing the technology, the researchers had 100 volunteers type the word ＂touch＂four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.28. Why do the researchers develop the smart keyboard?A. To reduce pressure on keys.B. To improve accuracy in typingC. To replace the password system.D. To cut the cost of e-space protection.29. What makes the invention of the smart keyboard possible?A. Computers are much easier to operate.B. Fingerprint scanning techniques develop fast.C. Typing patterns vary from person to person.D. Data security measures are guaranteed.30. What do the researchers expect of the smart keyboard?A. It’ll be environment-friendly.B. It’ll reach consumers soon.C. It’ll be made of plastics.D. It’ll help speed up typing.31. Where is this text most likely from?A. A diary.B. A guidebookC. A novel.D.

That’s bad news for the environment – and our wallets – as these outdated devices consume much more energy than the newer ones that do the same things.To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life – from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation. Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.As we accumulated more devices, however, we didn’t throw out our old ones. “The living-room television is replaced and gets planted in the kids’ room, and suddenly one day, you have a TV in every room of the house,” said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We’re not just keeping these old devices – we continue to use them. According to the analysis of Babbitt’s team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions (排放) more than doubling during the 1992 to 2007 window.So what’s the solution (解决方案)? The team’s data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.32. What does the author think of new devices?A. They are environment-friendly.B. They are no better than the old.C. They cost more to use at home.D. They go out of style quickly.33. Why did Babbitt’s team conduct the research?A. To reduce the cost of minerals.B. To test the life cycle of a product.C. To update consumers on new technology.D. To find out electricity consumption of the devices.34. Which of the following uses the least energy?A. The box-set TV.B. The tablet.C. The LCD TV.D. The desktop computer.35. What does the text suggest people do about old electronic devices?A. Stop using them.B. Take them apart.C. Upgrade them.D. Recycle them.(2020全国卷II) 话题：海狸鼠毛皮的利用问题CWhen you were trying to figure out what to buy for the environmentalist on your holiday list, fur probably didn’t cross your mind. But some ecologists and fashion (时装）enthusiasts are tryingto bring back the market for fur made from nutria(海狸鼠).Unusual fashion shows in New Orleans and Brooklyn have（showcased）nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt-free fur-unless you understand that the nutria are destroying vast wetlands every year”,says Cree McCree, project director of Righteous Fur.Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month.Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non-native species（物种）.It’s destroying the environment. It’s them or us." says Michael Massimi, an expert in this field.The fur trade kept nutria check for decades，but when the market for nutria collapsed in the late 1980s，the cat-sized animals multiplied like crazy.Biologist Edmond Mouton runs the nutria control program for Louisiana. He s ays it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur.Then there’s Righteous Fur and its unusual fashion. Morgan says，“To give people a guilt-free option that they can wear without someone throwing paint on them—1 think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable.

Developed by two doctors in the U.S. Department of Agriculture, it’s an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it’s all but impossible to find natural substitutes. The only components required, though, are a 5＇ 5＇sheet of clear or slightly milky plastic, six feet of plastic tube, and a container—perhaps just a drinking cup —to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher’s productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up —and out —the side of the hole.Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet’s center down with a rock. The plastic should now form a cone(圆锥体) with 45-degree-angled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup.The solar still works by creating a greenhouse under the plastic. Ground water evaporates (蒸发) and collects on the sheet until small drops of water form, run down the material and fall off into the cup. When the container is full, you can suck the refreshment zxxk out through the tube, and won’t have to break down the still every time you need a drink.32. What do we know about the solar still equipment from the first paragraph?A. It’s delicate.B. It’s expensive.C. It’s complex.D. It’s portable.33. What does the underlined phrase “the water catcher” in paragraph 2 refer to?A. The tube.B. The still.C. The hole.D. The cup.34. What’s the last step of constructing a working solar still?A. Dig a hole of a certain size.B. Put the cup in place.C. Weight the sheet’s center down.D. Cover the hole with the plastic sheet.35. When a solar still works, drops of water come into the cup form .A. the plastic tubeB. outside the holeC. the open airD. beneath the sheet（2016全国卷I）话题: 不同文化背景下的沉默内涵The meaning of silence varies among cultural groups. Silences may be thoughtful, or they may be empty when a person has nothing to say.A silence in a conversation may also show stubbornness, or worry. Silen ce may be viewed by some cultural groups as extremely uncomfortable; therefore attempts may be made to fill every gapwith conversation. Persons in other cultural groups value silence and vie w it as necessary for understanding a person's needs.Many Native Americans value silence and feel it is a basic part of co mmunicating among people, just as some traditional Chinese and Thai persons do. Therefore, when a person from one of these cultures is spea king and suddenly stops, what maybe implied(暗示) is that the person wants the listener to consider what has been said before continuing. In these cultures, silence is a call for reflection.Other cultures may use silence in other ways, particularly when dealing with conflicts among people or in relationships of people with different amounts of power. For example, Russian, French, and Spanish persons may use silence to show agreement between parties about the topic under discussion. However, Mexicans may use silence when instructions are given by a person inauthority rather than be rude to that person by arguing with him or her. In still another use, persons in Asian cultures may view silence as a sign of respect, particularly to an elder or a person in authority.Nurses and other care-givers need to be aware of the possible meanings of silence when they come across the personal anxiety their patients may be experiencing. Nurses should recognize their own personal and cultural construction of silence so that a patient’s silence is not interrupted too early or allowed to go on unnecessarily. A nurse who understands the healing(治愈) value of silence can use this understanding to assist in the care of patients from their own and from other cultures.32.What does the author say about silence in conversations?A.It implies anger.B.It promotes friendship.C.It is culture-specific.D.It is content-based.33.Which of the following people might regard silence as a call for careful thought?A.The Chinese.B.The French.C.The Mexicans.D.The Russians.34.What does the author advise nurses to do about silence?A.Let it continue as the patient pleases.B.Break it while treating patients.C.Evaluate its harm to patients.D.Make use of its healing effects.35.What may be the best title for the text?A.Sound and SilenceB.What It Means to Be SilentC.Silence to Native AmericansD.Speech Is Silver; Silence Is Gold参考答案：DACCDCBAADBAAADBDBCDCADB。

(完整)高考英语阅读理解科普类说明文4篇--较难(有答案)

高考英语说明文4篇1Here is an astonishing and significant fact: Mental work alone can’t makeus tire. It sounds absurd/əb'sɜːd/荒谬的. But a years ago, scientists tried to find out how long the human brain could labor without reaching a stage 阶段of fatigue /fə'tiːg/(疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we tooka drop of blood from a day laborer劳动者, we would find it fullof fatigue toxins /'tɒksɪn/ (毒素) and fatigue products. But if wetook blood from the brain of an Albert Einstein, it would show nofatigue toxins at the end of the day.So far as the brain is concerned, it can work as well and swiftly很快地at the end of eight or even twelve hours of effort as at the beginning. The brain istotally tireless. So what makes us tired?Some scientists declare that most of our fatigue comes from our mental and emotional(情绪的) attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin /'ɒrɪdʒɪn/起源. In fact, fatigue of purely physical origin is rare.”Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”What kinds of emotions make sitting workers tired? Joy? Satisfaction?No! A feeling of being bored, anger, anxiety/æŋ'zaɪətɪ/焦虑, tenseness紧张, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.1. What surprised the scientists a few years ago?A. Fatigue toxins could hardly be found in a laborer’s blood.B. Albert Einstein didn’t feel worn after a day’s work.C. The brain could work for many hours without fatigue.D. A mental worker’s blood was filled with fatigue toxins.2. According to the author, which of the following can make sitting workers tired?A. Challenging mental work.B. Unpleasant emotions.C. Endless tasks.D. Physical labo3. What’s the author’s attitude towards the scientists’ idea?A. He agrees with them.B. He doubts them.C. He argues against them.D. He hesitates to accept them.4. We can infer from the passage that in order to stay energetic, sitting workers need to ________.A. have some good food.B. enjoy their workC. exercise regularlyD. discover fatigue toxins2They baby is just one day old and has not yet left hospital. She is quietbut alert /ə'lɜːt/（警觉）. Twenty centimeters厘from her face researchershave placed a white card with two black spots on it. She stares at it carefully.A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze（凝视）starts to lose its focus — until a third, with three black spots,is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness 名，新奇? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three,or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise （同样地）when the researchers started with drumbeats and moved to spots.5. The experiment described in Paragraph 1 is related to the baby’s__.A. sense of hearingB. sense of sightC. sense of touch D sense of smell6. Babies are sensitive to the change in______.A. the size of cardsB. the colour of picturesC. the shape of patternsD. the number of objects7. Why did the researchers test the babies with drumbeats?A. To reduce the difficulty of the experiment.B. To see howbabies recognize sounds.C. To carry their experiment further.D. To keep the babies’interest.8. Where does this text probably come from?A. Science fiction.B. Children’s literature.C.

What they found instead was a sky so brightene by the city’s lights that it darkened the light of the meteors passing overhead. “My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointments.”Astronomers- /ə'strɒnəmə/n. 天文学家--scientists who study stars and planets---- have beencomplaining about this problem for decades.

英语写作说明文(优秀5篇)

英语写作说明文（优秀5篇）英语写作说明文篇一It is important to make sure that others know about your strengths and accomplishments; if you are not so,you will be never successful in life.If people are unaware of your talents and other good qualities, you obviously will not stand out among your peers. To be successful you not only have to work hard, but you have to make sure others know you work hard, as well. Of course you should let others know of your strength and accomplishments, but the best way to let them know is by showing, not by just telling.College applications-or applications of any kind-are a perfect example. Colleges want what kind of student you are and what kind of student you will be in college. You must show them that you are a good student and that you are interested in whatever you want to study. But in the essay, you cannot just state that you are a good student, are hardworking, and enjoy mathematics; you must show them. If you are interested in mathematics, then you probably did something in high school related to mathematics, such as the math club. In your essay, you must be sure to mention your participation in math club, but also activities your math club in order to show colleges that you will be active in your mathematics major. If you simply state that you like math, colleges will not be as impressed.It is important to let others know of your achievements; otherwise you will not be successful in life. The field of science can provide many examples of the validity of this statement. In science, communicating your discoveries is as important as discovery things in the first place. Everybody knows that the scientists Watson and Crick discovered the double-helix structure of DNA. Many people are not aware that this model was first theorized by a female scientist working in the same lab as Watson and Crick. However, Watson and Crick published their findings before the woman published her own findings. In science, credit is given to whoever publishes first, so the Watson and Crick are given full credit for the discovery of the double-helix structure of DNA. In order to be successful, you must let other people know of your accomplishments.Granted, there is a fine line between letting people know about your accomplishments and simply showing off.Nobody likes a show-off, so you must be careful not to rub people the wrong way with your success. People always say that actions speak louder than words, which is good advice to keep in mind when you are trying to let other peopleknow of your success. Don't just tell people you're good at writing. Start a blog and show people how accomplished of a writer you are.The key to success is to play to your strengths and to not be shy about showing other people your talents.

Fred Epstein, in his book I Make It to Five, tells a story he heard from one of his friends about Tom, a four-year-old boy with a cancer in his back bone. He came through several operations and a lot of pain by mastering his imagination.Tom loved to pretend, and he particularly loved to play superheroes. Dr. Epstein explained that it was actually a brilliant way for his young mind to handle the terrifying and painful life he led.The day before his third trip to the operating room, Tom was terribly afraid. “ Maybe I could go as Superman,” he whispered to his mom. Hearing this, the mother hesitated for while. She has avoided buying the expensive costume(戏装), but finally she agreed.The next day Tom appeared as the powerful Superman, showing off through the hospital halls and coolly waving his hand to the people greeting him along the way. And Tom, with the strength of his fantasy, successfully made it through the operation.The power of imagination need not be reserved for children only. We all have the power to use our fantasies to attempt things we never thought possible, to go through those things that seem impossible, and to achieve what we never believed we could. Just as Dr. Epstein puts it, “If you can dream it, you can do it.”It doesn’t mean that y ou should dress as a superhero for your next job interview. But, next time you are tested in a way that seems impossible, imagine what it would take to overcome it. Become the person you need to become to win over your challenge and do it in your mind first. So, let your imagination run wild, and dare to dream.18. What do we know about Tom?A. He was seriously ill.B. He was a dishonest boy.C. He was crazy about magic.D. He was Dr. Epstein’s patient.19. What can be inferred about Tom’s mother?A. She was a rich lady.B. She refused Tom’s request.C. She wanted Tom to be a superhero.D. She wanted to get Tom through the pain.20. When Tom went for the third operation, he_________.A. pretended to be painfulB. acted like a superheroC. appeared in poor spiritsD. argued with his mother21. In the last paragraph, you are advised________.A. to go through some difficult testsB. to wake up from your wild dreamsC. to become a powerful person in your mindD. to wear expensive clothes for job interviews22. What is the purpose of the passage?A. To tell us an interesting story.B. To help us make right decisions.C. To advise us to care about children.D. To encourage us to use our imagination.。

高考英语阅读理解-说明文8篇真题训练

高考英语复习阅读理解专练说明文8篇Passage 1(2017北京,C)Measles(麻疹), which once killed 450 children each year and disabled even more, was nearly wiped out in the United States 14 years ago by the universal use of the MMR vaccine(疫苗). But the disease is making a comeback, caused by a growing anti-vaccine movement and misinformation that is spreading quickly. Already this year, 115 measles cases have been reported in the USA, compared with 189 for all of last year.The numbers might sound small, but they are the leading edge of a dangerous trend. When vaccination rates are very high, as they still are in the nation as a whole, everyone is protected. This is called“herd immunity”, which protects the people who get hurt easily, including those who can’t be vaccinated for medical reasons, babies too young to get vaccinated and people on whom the vaccine doesn’t work.But herd immunity works only when nearly the whole herd joins in. When some refuse vaccination and seek a free ride, immunity breaks down and everyone is in even bigger danger.That’s exactly what is happening in small neighborhoods around the country from Orange County, California, where 22 measles cases were reported this month, to Brooklyn, N.Y., where a 17-year-old caused an outbreak last year.The resistance to vaccine has continued for decades, and it is driven by a real but very small risk. Those who refuse to take that risk selfishly make others suffer.Making things worse are state laws that make it too easy to opt out(决定不参加)of what are supposed to be required vaccines for all children entering kindergarten. Seventeen states allow parents to get an exemption(豁免), sometimes just by signing a paper saying they personally object to a vaccine.Now, several states are moving to tighten laws by adding new regulations for opting out. But no one does enough to limit exemptions.Parents ought to be able to opt out only for limited medical or religious reasons. But personal opinions?Not good enough. Everyone enjoys the life-saving benefits vaccines provide, but they’ll exist only as long as everyone shares in the risks.1.The first two paragraphs suggest that .A.a small number of measles cases can start a dangerous trendB.the outbreak of measles attracts the public attentionC.anti-vaccine movement has its medical reasonsrmation about measles spreads quickly2.Herd immunity works well when .A.exemptions are allowedB.several vaccines are used togetherC.the whole neighborhood is involved inD.new regulations are added to the state laws3.What is the main reason for the comeback of measles?A.The overuse of vaccine.B.The lack of medical care.C.The features of measles itself.D.The vaccine opt-outs of some people.4.What is the purpose of the passage?A.To introduce the idea of exemption.B.To discuss methods to cure measles.C.To stress the importance of vaccination.D.To appeal for equal rights in medical treatment.Passage 2(2017天津,A)Suppose you’re in a rush, feeling tired, not paying attention to your screen, and you send an email that could get you in trouble.Realisation will probably set in seconds after you’ve clicked “send”. You freeze in horror and burn with shame.What to do?Here are four common email accidents, and how to recover.Clicking “send”too soonDon’t waste your time trying to find out if the receiver has read it yet. Write another email as swiftly as you can and send it with a brief title explaining that this is the correct version and the previous version should be ignored.Writing the wrong nameThe sooner you notice, the better. Respond quickly and briefly, apologising for your mistake. Keep the tone measured:don’t handle it too lightly, as people can be offended, especially if your error suggests a misunderstanding of their culture(i.e. incorrect ordering of Chinese names).Clicking “reply all”unintentionallyYou accidentally reveal(透露)to the entire company what menu choices you would prefer at the staff Christmas dinner, or what holiday you’d like to take. In this instance, the best solution is to send a quick, light-hearted apology to explain your awkwardness. But it can quickly rise to something worse, when everyone starts hitting “reply all”to join in a long and unpleasant conversation. In this instance, step away from your keyboard to allow everyone to calm down.Sending an offensive message to its subjectThe most awkward email mistake is usually committed in anger. You write an unkind message about someone, intending to send it to a friend, but accidentally send it to the person you’re discussing. In that case, ask to speak in person as soon as possible and say sorry. Explain your frustrations calmly and sensibly—see it as an opportunity to clear up any difficulties you may have with this person.1.After realising an email accident, you are likely to feel .A.curiousB.tiredC.awfulD.funny2.If you have written the wrong name in an email, it is best to .A.apologise in a serious mannerB.tell the receiver to ignore the errorC.learn to write the name correctlyD.send a short notice to everyone3.What should you do when an unpleasant conversation is started by your “reply all”email?A.Try offering other choices.B.Avoid further involvement.C.Meet other staff members.D.Make a light-hearted apology.4.How should you deal with the problem caused by an offensive email?A.By promising not to offend the receiver again.B.By seeking support from the receiver’s friends.C.By asking the receiver to control his anger.D.By talking to the receiver face to face.5.What is the passage mainly about?A.Defining email errors.B.Reducing email mistakes.C.Handling email accidents.D.Improving email writing.Passage 3(2017天津,D)I read somewhere that we spend a full third of our lives waiting. But where are we doing all of this waiting, and what does it mean to an impatient society like ours?To understand the issue, let’s take a look at three types of “waits”.The very purest form of waiting is the Watched-Pot Wait. It is without doubt the most annoying of all. Take filling up the kitchen sink(洗碗池)as an example. There is absolutely nothing you can do while this is going on but keep both eyes fixed on the sink until it’s full. During these waits, the brain slips away from thebody and wanders about until the water runs over the edge of the counter and onto your socks. This kind of wait makes the waiter helpless and mindless.A cousin to the Watched-Pot Wait is the Forced Wait. This one requires a bit of discipline. Properly preparing packaged noodle soup requires a Forced Wait. Directions are very specific.“Bring three cups of water to boil, add mix, simmer three minutes, remove from heat, let stand five minutes.”I have my doubts that anyone has actually followed the procedures strictly. After all, Forced Waiting requires patience.Perhaps the most powerful type of waiting is the Lucky-Break Wait. This type of wait is unusual in that it is for the most part voluntary. Unlike the Forced Wait, which is also voluntary, waiting for your lucky break does not necessarily mean that it will happen.Turning one’s life into a waiting game requires faith and hope, and is strictly for the optimists among us. On the surface it seems as ridiculous as following the directions on soup mixes, but the Lucky-Break Wait well serves those who are willing to do it. As long as one doesn’t come to rely on it, wishing for a few good things to happen never hurts anybody.We certainly do spend a good deal of our time waiting. The next time you’re standing at the sink waiting for it to fill while cooking noodle soup that you’ll have to eat until a large bag of cash falls out of the sky, don’t be desperate. You’re probably just as busy as the next guy.1.While doing a Watched-Pot Wait, we tend to .A.keep ourselves busyB.get absent-mindedC.grow anxiousD.stay focused2.What is the difference between the Forced Wait and the Watched-Pot Wait?A.The Forced Wait requires some self-control.B.The Forced Wait makes people passive.C.The Watched-Pot Wait needs directions.D.The Watched-Pot Wait engages body and brain.3.What can we learn about the Lucky-Break Wait?A.It is less voluntary than the Forced Wait.B.It doesn’t always bring the desired result.C.It is more fruitful than the Forced Wait.D.It doesn’t give people faith and hope.4.What does the author advise us to do the next time we are waiting?A.Take it seriously.B.Don’t rely on others.C.Do something else.D.Don’t lose heart.5.The author supports his view by .A.exploring various causes of “waits”B.describing detailed processes of “waits”C.analyzing different categories of “waits”D.revealing frustrating consequences of “waits”Passage 4(2017浙江,B)Getting less sleep has become a bad habit for most American kids. According to a new survey(调查) by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.How much sleep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day!Adults need about eight hours. For most school-age children, ten hours is ideal(理想的). But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime?Watch TV.“More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone,”says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers’bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago,schools in Edina, Minnesota, changed the start time from 7:25 am to 8:30 am. Students, parents and teachers are pleased with the results.1.What is the new National Sleep Foundation survey on?A.American kids’sleeping habits.B.Teenagers’sleep-related diseases.C.Activities to prevent sleeplessness.D.Learning problems and lack of sleep.2.How many hours of sleep do 11-year-olds need every day?A.7 hours.B.8 hours.C.10 hours.D.18 hours.3.Why do teenagers go to sleep late according to Carskadon?A.They are affected by certain body chemicals.B.They tend to do things that excite them.C.They follow their parents’examples.D.They don’t need to go to school early.Passage 5(2017课标全国Ⅰ,C)Some of the world’s most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO(United Nations Educational, Scientific and Cultural Organization)recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(联合)voice across cultures.Despite the celebrations, though, in the U.S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.It’s Jason Moran’s job to help change that. As the Kennedy Center’s artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.“Jazz seems like it’s not really a part of the American appetite,”Moran tells National Public Radio’s reporter Neal Conan.“What I’m hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and white anymore. It’s actually color, and it’s actually digital.”Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost.“The music can’t be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same,”says Moran.Last year, Moran worked on a project that arranged Fats Waller’s music for a dance party,“just to kind of put it back in the mind that Waller is dance music as much as it is concert music,”says Moran.“For me, it’s the recontextualization. In music, where does the emotion(情感)lie?Are we, as humans, gaining any insight(感悟)on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and ourthoughts?Sometimes we lose sight that the music has a wider context,”says Moran,“so I want to continue those dialogues. Those are the things I want to foster.”1.Why did UNESCO set April 30 as International Jazz Day?A.To remember the birth of jazz.B.To protect cultural diversity.C.To encourage people to study music.D.To recognize the value of jazz.2.What does the underlined word“that”in paragraph 3 refer to?A.Jazz becoming more accessible.B.The production of jazz growing faster.C.Jazz being less popular with the young.D.The jazz audience becoming larger.3.What can we infer about Moran’s opinion on jazz?A.It will disappear gradually.B.It remains black and white.C.It should keep up with the times.D.It changes every 50 years.4.Which of the following can be the best title for the text?A.Exploring the Future of JazzB.The Rise and Fall of JazzC.The Story of a Jazz MusicianD.Celebrating the Jazz DayPassage 6(2016课标Ⅲ,C)If you are a fruit grower—or would like to become one—take advantage of Apple Day to see what’s around. It’s called Apple Day but in practice it’s more like Apple Month. The day itself is on October 21, but since it has caught on, events now spread out over most of October around Britain.Visiting an apple event is a good chance to see, and often taste, a wide variety of apples. To people who are used to the limited choice of apples such as Golden Delicious and Royal Gala in supermarkets, it can be quite an eye opener to see the range of classical apples still in existence, such as Decio which was grown by the Romans. Although it doesn’t taste of anything special, it’s still worth a try, as is the knobbly(多疙瘩的)Cat’s Head which is more of a curiosity than anything else.There are also varieties developed to suit specific local conditions. One of the very best varieties for eating quality is Orleans Reinette, but you’ll need a warm, sheltered place with perfect soil to grow it, so it’s a pipe dream for most apple lovers who fall for it.At the events, you can meet expert growers and discuss which ones will best suit your conditions, and because these are family affairs, children are well catered for with apple-themed fun and games.Apple Days are being held at all sorts of places with an interest in fruit, including stately gardens and commercial orchards(果园). If you want to have a real orchard experience, try visiting the National Fruit Collection at Brogdale, near Faversham in Kent.1.What can people do at the apple events?A.Attend experts’lectures.B.Visit fruit-loving families.C.Plant fruit trees in an orchard.D.Taste many kinds of apples.2.What can we learn about Decio?A.It is a new variety.B.It has a strange look.C.It is rarely seen now.D.It has a special taste.3.What does the underlined phrase“a pipe dream”in Paragraph 3 mean?A.A practical idea.B.A vain hope.C.A brilliant plan.D.A selfish desire.4.What is the author’s purpose in writing the text?A.To show how to grow apples.B.To introduce an apple festival.C.To help people select apples.D.To promote apple research.Passage 7(2015课标Ⅰ,C)Salvador Dali(1904—1989)was one of the most popular of modern artists.The Pompidou Centre in Paris is showing its respect and admiration for the artist and his powerful personality with an exhibition bringing together over 200 paintings,sculptures,drawings and more.Among the works and masterworks on exhibition the visitor will find the best pieces,most importantly The Persistence ofMemory.There is also L’Enigme sans Fin from 1938,works on paper,objects,and projects for stage and screen and selected parts from television programmes reflecting the artist’s showman qualities.The visitor will enter the World of Dali through an egg and is met with the beginning,the world of birth.The exhibition follows a path of time and subject with the visitor exiting through the brain.The exhibition shows how Dali draws the viewer between two infinities(无限).“From the infinity small to the infinity large,contraction and expansion coming in and out of focus:amazing Flemish accuracy and the showy Baroque of old painting that he used in his museum-theatre in Figueras,”explains the Pompidou Centre.The fine selection of the major works was done in close collaboration(合作)with the Museo Nacional Reina Sofia in Madrid,Spain,and with contributions from other institutions like the Salvador Dali Museum in St.Petersburg,Florida.1.Which of the following best describes Dali according to Paragraph 1?A.Optimistic.B.Productive.C.Generous.D.Traditional.2.What is Dali’s The Persistence of Memory considered to be?A.One of his masterworks.B.A successful screen adaptation.C.An artistic creation for the stage.D.One of the best TV programmes.3.How are the exhibits arranged at the World of Dali?A.By popularity.B.By importance.C.By size and shape.D.By time and subject.4.What does the word“contributions”in the last paragraph refer to?A.Artworks.B.Projects.C.Donations.D.Documents. Passage 8(2014课标Ⅰ,B)Passenger pigeons(旅鸽)once flew over much of the United States in unbelievable numbers.Written accounts from the 18th and 19th centuries described flocks(群)so large that they darkened the sky for hours.It was calculated that when its population reached its highest point,there were more than 3 billion passenger pigeons—a number equal to 24 to 40 percent of the total bird population in the United States,making it perhaps the most abundant bird in the world.Even as late as 1870 when their numbers had already become smaller,a flock believed to be 1 mile wide and 320 miles(about 515 kilometers)long was seen near Cincinnati.Sadly,the abundance of passenger pigeons may have been theirundoing.Where the birds were most abundant,people believed there was an ever-lasting supply and killed them by the mercial hunters attracted them to small clearings with grain,waited until pigeons had settled to feed,then threw large nets over them,taking hundreds at a time.The birds were shipped to large cities and sold in restaurants.By the closing decades of the 19th century,the hardwood forests where passenger pigeons nested had been damaged by Americans’need forwood,which scattered(驱散)the flocks and forced the birds to go farthernorth,where cold temperatures and spring storms contributed to their decline.Soon the great flocks were gone,never to be seen again.In 1897,the state of Michigan passed a law prohibiting the killing of passenger pigeons,but by then,no sizable flocks had been seen in the state for 10 years.The last confirmed wild pigeon in the United States was shot by a boy in Pike County,Ohio,in 1900.For a time,a few birds survived under human care.The last of them,known affectionately as Martha,died at the Cincinnati Zoological Garden on September 1,1914.1.In the 18th and early 19th centuries, passenger pigeons .A.were the biggest bird in the worldB.lived mainly in the south of AmericaC.did great harm to the natural environmentD.were the largest bird population in the US2.The underlined word “undoing”probably refers to the pigeons’.A.escapeB.ruinC.liberationD.evolution3.What was the main reason for people to kill passenger pigeons?A.To seek pleasure.B.To save other birds.C.To make money.D.To protect crops.4.What can we infer about the law passed in Michigan?A.It was ignored by the public.B.It was declared too late.C.It was unfair.D.It was strict.答案全解全析Passage 1[语篇解读] 本文是一篇说明文。

But he finds that the factory is giving off large quantities of heavy smoke which makes him feel very puzzled, “Why does the factory forbid people to smoke while the factory itself emits so much poisonous smoke?”Nowadays, many factories know the danger of smoking to themselves and don’t allow people smoking in the factory. However, they don’t pay any attention to the danger that they cause to the whole society. And they let out lots of polluted smoke which does great harm to our environment.In my opinion, we could live without most of the industrial products, but we could not survive without nature! Therefore, something must be done to prevent the pollution caused by all factories!高三英语说明文的作文21、你接受了一项写作任务，为英语校报写一篇科技报道。

高考英语阅读理解C专练5篇

高考英语阅读理解C专练5篇阅读理解C专练5篇Passage 1(2017江苏,C)A new commodity brings about a highly profitable, fast-growing industry, urgingantitrust(反垄断)regulators to step in to check those who control its flow. A century ago, the resource in question was oil. Now similar concerns are being raised by the giants(巨头)that deal in data, the oil of the digital age. The most valuable firms are Google, Amazon, Facebook and Microsoft. All look unstoppable.Such situations have led to calls for the tech giants to be broken up. But size alone is not a crime. The giants’ success has benefited consumers. Few want to live without search engines or a quick delivery. Far from charging consumers high prices, many of these services are free(users pay,in effect, by handing over yet more data). And the appearance of new-born giants suggests that newcomers can make waves, too.But there is cause for concern. The internet has made data abundant, all-present and far more valuable, changing the nature of data and competition. Google initially used the data collected from users to target advertising better. But recently it has discovered that data can be turned into new services:translation and visual recognition, to be sold to other companies. Internet companies’ control of data gives them enormous power. So they have a“God’s eye view”of activities in their own markets and beyond.This nature of data makes the antitrust measures of the past less useful. Breaking up firms like Google into five small ones would not stop remaking themselves:in time, one of them wouldbecome great again. A rethink is required—and as a new approach starts to become apparent, two ideas stand out.The first is that antitrust authorities need to move from the industrial age into the 21st century. When considering a merger(兼并), for example, they have traditionally used size to determine when to step in. They now need to take into account the extent of firms’ data assets(资产)when assessing the impact of deals. The purchase price could also be a signal that an established company is buying a new-born threat. When this takes place, especially when anew-born company has no revenue to speak of, the regulators should raise red flags.The second principle is to loosen the control that providers of on-line services have over data and give more to those who supply them. Companies could be forced to reveal to consumers what information they hold and how much money they make from it. Governments could order the sharing of certain ki nds of data, with users’ consent.Restarting antitrust for the information age will not be easy. But if governments don’t want a data economy controlled by a few giants, they must act soon.1.Why is there a call to break up giants?A.They have controlled the data market.B.They collect enormous private data.C.They no longer provide free services.D.They dismissed some new-born giants.2.What does the technological innovation in Paragraph 3 indicate?A.Data giants’ technology is very expensive.B.Google’s i dea is popular among data firms.C.Data can strengthen giants’ controlling position.D.Data can be turned into new services or products.3.By paying attention to firms’ data assets, antitrust regulators could .A.kill a new threatB.avoid the size trapC.favour bigger firmsD.charge higher prices4.What is the purpose of loosening the giants’ control of data?A.Big companies could relieve data security pressure./doc/ad13018697.html,ernments could relieve their financial pressure.C.Consumers could better protect their privacy.D.Small companies could get more opportunities.答案[语篇解读]本文为说明文,属于社科类文章。

高考英语说明文5篇1Here is an astonishing and significant fact: Mental work alone can’t make us tire. It sounds absurd. But a years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we would find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?Some scientists declare that most of our fatigue comes from our mental and emotional(情绪的) attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare.”Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.1. What surprised the scientists a few years ago?A. Fatigue toxins could hardly be found in a laborer’s blood.B. Albert Einstein didn’t feel worn after a day’s work.C. The brain could work for many hours without fatigue.D. A mental worker’s blood was filled with fatigue toxins.2. According to the author, which of the following can make sitting workers tired?A. Challenging mental work.B. Unpleasant emotions.C. Endless tasks.D. Physical labor3. What’s the author’s attitude towards the scientists’ idea?A. He agrees with them.B. He doubts them.C. He argues against them.D. He hesitates to accept them.4. We can infer from the passage that in order to stay energetic, sitting workers need to ________.A. have some good food.B. enjoy their workC. exercise regularlyD. discover fatigue toxins2They baby is just one day old and has not yet left hospital. She is quiet but alert （警觉）. Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze（凝视） starts to lose its focus — until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise （同样地）when the researchers started with drumbeats and moved to spots.5. The experiment described in Paragraph 1 is related to the baby’s__.A. sense of hearingB. sense of sightC. sense of touchD. sense of smell6. Babies are sensitive to the change in______.A. the size of cardsB. the colour of picturesC. the shape of patternsD. the number of objects7. Why did the researchers test the babies with drumbeats?A. To reduce the difficulty of the experiment.B. To see how babies recognize sounds.C. To carry their experiment further.D. To keep the babies’interest.8. Where does this text probably come from?A. Science fiction.B. Children’s literature.C. An advertisement.D.A science report3Last night’s meteor(流星) shower left many people in the community dissatisfied and demanding answers. According to Gabe Rothsclild, Emerald Valley’s mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city’s lights that it darkened the light of the meteors passing overhead.“My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointments.”Astronomers---scientists who study stars and planets----have been complaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark-Sky Association. “100 million birds a year throughout North America die in crashes with lighted buildings and towers.”Countless more animals casualties(伤亡）result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase person’s chances of getting cancer.Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona, has enforced lighting regulations in its city in order to assist astronomers at the LowellObservatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.9.It happened last night thatA. the city’s lights affected the meteor watchingB. the meteors flew past before being noticedC. the city light show attracted many peopleD. the meteor watching ended up a social outing10. What do the astronomers complain about?A. Meteor showers occur less often than beforeB. Their observation equipment is in poor repairC. Light pollution has remained unsolved for yearsD. Their eyesight is failing due to artificial lighting11. What the author concerned about according to Paragraph 4?A. Birds may take other migration pathsB. Animals living habits may change suddenlyC. Varieties of animals will become sharply reducedD. Animals’ survival is threatened by outdoor lighting12. Lighting regulations in Flagstaff, Arizona are put into effect toA. Lessen the chance of getting cancerB. create an ideal observation conditionC. ensure citizens a good sleep at nightD. enable all creatures to live in harmony13.What message does the author most want to give us?A. Saving wildlife is saving ourselvesB. Great efforts should be made to save energyC. Human activities should be environmentally friendlyD. New equipment should be introduced for space study4Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know，however，that they existed over 5,500years ago in ancient Asia.The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5，100 years old. Evidence suggests thatwheels for transport didn't become popular for .while, though . This could be because animals did a perfectly good job of carrying farming tools and humans around.But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren't going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modern road design.In the mid-1700s,a Frenchman came up with a new design of road--a base layer (层)of large stones covered with a thin layer of smaller atones. A Scotsman improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same time, metal hubs(the central part of a wheel) came into being, followed by the Wheels were invented in 1967, sixty years after the appearance of tarmacked roads(泊油路). As wheel design took off, vehicles got faster and faster.14. What might explain why transport wheels didn’t become popular for some time?A. Few knew how to use transport wheels.B.

Fred Epstein, in his book I Make It to Five, tells a story he heard from one of his friends about Tom, a four-year-old boy with a cancer in his back bone. He came through several operations and a lot of pain by mastering his imagination.Tom loved to pretend, and he particularly loved to play superheroes. Dr. Epstein explained that it was actually a brilliant way for his young mind to handle the terrifying and painful life he led.The day before his third trip to the operating room, Tom was terribly afraid. “ Maybe I could go as Superman,” he whispered to his mom. Hearing this, the mother hesitated for while. She has avoided buying the expensive costume(戏装), but finally she agreed.The next day Tom appeared as the powerful Superman, showing off through the hospital halls and coolly waving his hand to the people greeting him along the way. And Tom, with the strength of his fantasy, successfully made it through the operation.The power of imagination need not be reserved for children only. We all have the power to use our fantasies to attempt things we never thought possible, to go through those things that seem impossible, and to achieve what we never believed we could. Just as Dr. Epstein puts it, “If you can dream it, you can do it.”It doesn’t mean that you should dress as a superhero for your next job interview. But, next time you are tested in a way that seems impossible, imagine what it would take to overcome it. Become the person you need to become to win over your challenge and do it in your mind first. So, let your imagination run wild, and dare to dream.18. What do we know about Tom?A. He was seriously ill.B. He was a dishonest boy.C. He was crazy about magic.D. He was Dr. Epstein’s patient.19.
