2020届高考英语备考专题17阅读理解之说明文无答案

专题01 阅读理解之说明文（一）1.（2020届安徽省合肥市高三第二次质检）People often talk about cultural differences between western and eastern countries, but how about the western world itself? Surprisingly, a closer look at it can reveal a good many curious details.The most obvious characteristic of the majority of Americans is that they smile a lot. It does not matter whether they have a strong reason to smile; they do it, sometimes simply because they have to. A smile is not just a powerful marketing tool but also a way to show that someone is friendly, and that life in general is fine. Europeans, on the contrary, prefer to keep a more neutral (不露声色的) facial expression. They smile mostly when they are in a good mood, or feel amused; if not, a European’s face will remain neutral, or even dull. In Russia, for example, there is a proverb saying that laughing for no reason is a sign of a fool. It does not mean that Europeans are serious, or that they do not have a sense of humor.The same refers to communication in general. Americans are extremely communicative; small talk and chats are common. Europeans talk mostly when there is something to say, and rarely enter communication just for the purpose of talking to other people. American people prefer to express what they think carefully, considering how it might affect surrounding people. Europeans are more straightforward, even with unfamiliar people. A European friend will almost always voice their opinion on different occasions, and will not hesitate to remind you that you need to lose some weight or take a shower.It can be said that Americans are people of contrasts. They are open-minded, flexible, and ready to accept everything new enthusiastically; but at the same time, American society manages to bring up unbelievable conservatives. Americans are extremely politically correct, which, in most cases, is indeed a secure and beneficial practice, but it can also mess up daily or even private communication, sometimes preventing having close relationships. Europeans, on the contrary, are more straightforward, preferring to tell the truth in direct ways. Each way of communication is different — neither is correct or incorrect.4．What does the author say about smiling?A．It is culture-related within western countries.B．It is a powerful marketing tool across cultures.C．It is thought of as a sign of a fool in America.D．It is regarded as being socially necessary in Europe.5．What is typical of Europeans’ communication?A．Beating around the bush. B．Having small talk and chats.C．Hiding their feelings carefully. D．Expressing themselves openly.6．What does the underlined word “it” in the last paragraph refer to?A．Being straightforward. B．Being politically correct.C．Accepting everything new. D．Raising unbelievable conservatives.7．How is the text mainly developed?A．By analyzing cause and effect. B．By making comparisons.C．By classifying body language. D．By discussing research findings.【答案】4．A5．D6．B7．B【解析】本文是说明文。

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

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

阅读理解试题的中要考点之一是考查学生对词汇和句式的掌握。

说明文的词汇和句式的运用较别的体裁的文章难度更大。

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

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

【满分技巧】高考阅读理解中，说明文为主要体裁之一。

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

其中，说明文主要以细节事实、主旨大意和猜测词义三方面问题为主。

一、词义猜测类题型阅读理解题中常要求学生猜测某些单词或短语的意思。

历年英语高考题中均有此类题目，有的文章尽管没有专门设题，但由于文章中常常出现生词，因此，词义的猜测还是贯穿在文章的阅读理解之中。

解这类题目一般是通过上下文去理解或根据构词法去猜测。

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

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

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

这时，就需要运用生活经验和普通常识确定词义。

说明文阅读高分技巧专项练习AMost damagingly, anger weakens a person's ability to think clearly and keepcontrol over his behavior. The angry person loses objectivity in evaluating theemotional significance of the person or situation that arouses his anger.Not everyone experiences anger in the same way; what angers one person may amuse another. The specific expression of anger also differs from person to person based on biological and cultural forces. In contemporary culture, physical expressionsof anger are generally considered too socially harmful to be tolerated. We no longer regard duels( 决斗 ) as an appropriate expression of anger resulting from one person's awareness of insulting behavior on the part of another.Anger can be identified in the brain, where the electrical activity changes.Under most conditions EEG ( 脑电图 ) measures of electrical activity show balancedactivity between the right and left prefrontal ( 额叶前部 ) areas. Behaviorally this corresponds to the general even-handed disposition ( 意向 ) that most of us possess most of the time. But when we are angry the EEG of the right and left prefrontalareas aren't balanced and as a result of this, we're likely to react. And ourbehavioral response to anger is different from our response to other emotions,whether positive or negative.Most positive emotions are associated with approach behavior: we move closerto people we like. Most negative emotions, in c ontrast, are associated with avoidance behavior: we move away from people and things that we dislike or that make us anxious. But anger is an exception to this pattern. The angrier we are ， the more likely we are to move towards the object of our anger. This corresponds to what psychologists refer to as offensive anger : the angry person moves closer in order to influenceand control the person or situation causing his anger. This approach-and-confrontbehavior is accompanied by a leftward prefrontal asymmetry ( 不对称 ) o f EEGactivity. Interestingly, this asymmetry lessens if the angry person can experience empathy( 同感 ) towards the individual who is bringing forth the angry response. In defensive anger, in contrast, the EEG asymmetry is directed to the right and the angry person feels helpless in the face of the anger-inspiring situation.1. The "duels" example in Paragraph 2 proves that the expression of a nger_________.A. usually has a biological basis2.What changes can be found in an angry brain?A.Balanced electrical activity can be spotted.B.Unbalanced patterns are found in prefrontal areas.C.Electrical activity corresponds to one's behaviour.D.Electrical activity agrees with one's disposition.3.Which of the following is typical of offensive anger?A.Approaching the source of anger.B. Trying to control what is disliked.C. Moving away from what is disliked.D. Feeling helpless in the face of anger.4.What is the key message of the last paragraph?A.How anger differs from other emotions.B.How anger relates to other emotions.C.Behavioral responses to anger.D.Behavioral patterns of anger.BWorking with a group of baboons ( 狒狒 ) in the Namibian desert, Dr. Alecia Carter of the Department of Zoology, Cambridge University set baboons learning tasksinvolving a novel food and a familiar food hidden in a box. Some baboons were given the chance to watch another baboon who already knew how to solve the task, whileothers had to learn for themselves. To work out how brave or anxious the baboonswere, Dr. Carter presented them either with a novel food or a threat in the form of amodel of a poisonous snake.She found that personality had a major impact on learning. The braver baboonslearnt, but the shy ones did not learn the task although they watched the baboonperform the task of finding the novel food just as long as the brave ones did. Ineffect, despite being made aware of what to do, they were still too shy to dowhat the experienced baboon did.The same held true for anxious baboons compared with calm ones. The anxiousindividuals learnt the task by observing others while those who were relaxed didnot, even though they spent more time watching.This mismatch between collecting social information and using it shows thatpersonality plays a key role in social learning in animals, something that haspreviously been ignored in studies on how animals learn to do things. The findingsare significant because they suggest that animals may perform poorly in cognitive( 认知的 ) tasks not because they aren’t cle ver enough to solve them, but becausethey are too shy or nervous to use the social information.The findings may impact how we understand the formation of culture in societies through social learning. If some individuals are unable to get information from othersbecause they don ’t associate with the knowledgeable individuals, or they are tooshy to use the information once they have it, information may not travel between allgroup members, preventing the formation of a culture based on social learning.5. What is the first paragraph mainly about?A. The design of Dr. Carter ’s research.B. The results of Dr. Carter ’s research.C. The purpose of Dr. Carter ’s research.D. The significance of Dr. Carter ’s research.6. According to the research, which baboons are more likely to complete a newlearning task?A. Those that have more experience.B. Those that can avoid potential risks.C. Those that like to work independently.D. Those that feel anxious about learning.7. Which best illustrates the“mismatch” m entioned in Paragraph 4?A. Some baboons are intelligent but slow in learning.B. Some baboons are shy but active in social activities.C. Some baboons observe others but don’t follow them.D. Some baboons perform new tasks but don’t concentrate.8. Dr. Carter ’s findings indicate that our culture might be formed through______.A. storing informationB. learning from each otherC. understanding different peopleD. travelling between social groups说明文阅读高分技巧专项练习参考答案A考点：考查科普知识类阅读。

第17题阅读理解The Japanese have always been at the forefront at deploying robots to perform jobs that are traditionally done by humans. Over the past year, humanoid robots have been seen helping customers at the Mitsubishi Bank and even filling in for human science communicators at museums. Therefore, it is not surprising to hear that the country has the world's first hotel that is staffed almost entirely by the Androids!The aptly(巧妙地）named Henn-na ("strange" in Japanese)Hotel which opened its doors on July 17 is located at Nagasaki's Huis Ten Bosch theme park.. It is the idea of Hideo Sawada, a Japanese businessman who is fascinated by the possibility of replacing humans with robots. His aim is to have this futuristic hotel be run mainly by the intelligent humanoids .Guests checking-in are welcomed by a family friendly English-speaking robot wearing a bow tie andbell-hop(侍者）hat. Though experienced at his job, he does request guests not to ask him "a difficult question "since he is after all," just a robot!"Those seeking a more" regular" experience, can approach the human-likeJapanese-speaking robot.When ready, visitors can request the robot "porters" to help carry belongings to their room. Those that need to stow away valuables can hand them to a helpful robot who will place them inside an individual safe box in exchange for a small fee. A one-foot-high concierge is available to provide information about the hotel's amenities, nearby attractions, and even order a taxi if needed.So how much does it cost to live in this crazy cool hotel? It depends on when you decide to go. During the low season, guests can get away with paying as little $ 60 a night for a basic room. However, during the peak season when rates are determined by an online auction, the price can get as high as $153.1. What is Hideo Sawada interested in?A. Making different kinds of robots.B. Taking the place of humans with robots.C. Setting up more hotels run by robots.D. Making robots more intelligent.【答案】B【解析】细节理解题。

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 could offer 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？all 1o soisgitieoco oll.A. It'll be environment-friendly.B. It'll reach consumers soon.C. It'll be made of plastics.D.

The microorganisms(微生物) from our bodies grow uncontrollably on surfaces of the International Space Station, so astronauts spend hours cleaning them up each week. How is NASA overcoming this very tiny big problem? It’s turning to a bunch of high school kids. But not just any kids. It depending on NASA HUNCH high school class, like the one science teachers Gene Gordon and Donna Himmelberg lead at Fairport High School in Fairport, New York.HUNCH is designed to connect high school classrooms with NASA engineers. For the past two years, Gordon’s students have been studying ways to kill bacteria in zero gravity, and they think they’re close to a solution(解决方案). “We don’t give the students any breaks. They have to do it just like NASA engineers,” says Florence Gold, a project manager.“There are no tests,” Gordon says. “There is no graded homework. There almost are no grades, other than‘Are you working towards your goal?’Basically, it’s ‘I’ve got to produce this product and then, at the end of year, present it to NASA.’ Engineers come and really do an in-person review, and…it’s not a very nice thing at time. It’s a hard business review of your product.”Gordon says the HUNCH program has an impact(影响) on college admissions and practical life skills. “These kids are so absorbed in their studies that I just sit back. I don’t teach.” And that annoying bacteria? Gordon says his students are emailing daily with NASA engineers about the problem, readying a workable solution to test in space.32. What do we know about the bacteria in the International Space Station?A. They are hard to get rid of.B. They lead to air pollution.C. They appear different forms.D. They damage the instruments.33.

The researchers then tested how the monkeys combined—or added—the symbols to get the reward.Here's how Harvard Medical School scientist Margaret Livingstone, who led the team, described the experiment: In their cages the monkeys were provided with touch screens. On one part of the screen, a symbol would appear, and on the other side two symbols inside a circle were shown. For example, the number 7 would flash on one side of the screen and the other end would have 9 and 8. If the monkeys touched the left side of the screen they would be rewarded with seven drops of water or juice; if they went for the circle, they would be rewarded with the sum of the numbers—17 in this example.After running hundreds of tests, the researchers noted that the monkeys would go for the higher values more than half the time, indicating that they were performing a calculation, not just memorizing the value of each combination.When the team examined the results of the experiment more closely, they noticed that the monkeys tended to underestimate(低估)a sum compared with a single symbol when the two were close in value—sometimes choosing, for example, a 13 over the sum of 8 and 6. The underestimation was systematic: When adding two numbers, the monkeys always paid attention to the larger of the two, and then added only a fraction(小部分)of the smaller number to it."This indicates that there is a certain way quantity is represented in their brains, "Dr. Livingstone says. “But in this experiment what they're doing is paying more attention to the big number than the little one.”32. What did the researchers do to the monkeys before testing them?A. They fed them.B. They named them.C. They trained them.D. They measured them.33. How did the monkeys get their reward in the experiment?A. By drawing a circle.B. By touching a screen.C. By watching videos.D. By mixing two drinks.34.

Scheduling more (laytime flights may reduce the influence of contrails ——the visible lines of white steam that many planes leave behind them in the sky.The role of contrails in climate change is still being studied, but some scientists believe they contribute to the greenhouse effect by trapping heat in the atmosphere.Nicola Stuber, first author of the study, suggests that contrails' overall impact on climate change is almost as big as that of aircraft? s carbon dioxide emissions (排放)over a hundred-year period. Aircraft are believed to be responsible for 2-3% of human carbon dioxide emissions. Like other high, thin clouds, contrails reflect sunlight back into space and cool the planet. However, they also trap energy in the atmosphere and increase the warming effect.Stuber and other scientists believe that the effect of the contrails is big. " On average, the green-house effect controls the effects of contrails,said Stuber, a meteorologist at England's University of Reading. "The warming effect is far greater for contrails left by night flights," Stuber added. "The cooling effect only happens (luring the day when the sun is up. During the night the greenhouse warming is no longer balanced and that is why the contribution of night-flight is so large. "Most commercial airline traffic occurs during daylight hours. For example, only one in four United Kingdom flights is a night flight, but those flights create some 60% of the warming created by contrails, the study reports.1. How do contrails increase the greenhouse effect?A. They give off heat.B. They absorb daylight.C. They trap heat in the atmosphere.D. They reflect sunlight back into space.2. What does the underlined word "they" in Paragraph 3 refer to?A. carbon dioxide emissionsB. contrailsC. flightsD. thin clouds3. What did Stuber explain about the contrails in Paragraph 4?A. What their function is.B. How they cool the Earth.C. Why they create big warming at night.D. How big their effect is.4. What can be a suitable title for the text?A. Airlines Should Schedule FlightsB. Night Flights Face a New ChallengeC. Airplane Contributes Most to Global WarmingD. More Day Flights May Reduce Global WarmingB（四省名校2019-2020学年高三第一次大联考）If you wear glasses, chances are you are smarter. Research published in the famous British journal Nature Communications has found that people who displayed higher levels of intelligence were almost 30 percent more likely to wear glasses.The scientists studied the genes of thousands of people between the ages of 16 and 102.The study showed intelligence can be connected to physical characteristics. One characteristic was eyesight. In out of 10 people who were more intelligent, there was a higher chance they needed glasses. Scientists also said being smarter has other benefits. It is connected to better health.It is important to remember these are connections which are not proven causes. Scientists call this correlation. Just because something is connected to something else does not mean one of those things caused the other. And it’s worth noting that what constitutes intelligence is subjective and can be difficult, ifnot impossible, to measure.Forget genes though. Plenty of proof shows wearing glasses makes people think you are more intelligent, even if you do not need glasses. A number of studies have found people who wear glasses are seen as smarter, hard-working and honest. Many lawyers use this idea to help win their cases. Lawyer Harvey Solves explained this. Glasses soften their appearance. He said Sometimes there has been a huge amount of proof showing that people he was defending broke the law. He had them wear glasses and they weren’t found guil ty.Glasses are also used to show someone is intelligent in movies and on TV. Ideas about people who wear glasses have begun to shift. People who do not need glasses sometimes wear them for fashion only. They want to look worldly or cool. But not everyone is impressed by this idea, though. GQ magazine said people who wear glasses for fashion are trying too hard to look smart and hip (时髦的). However, that hasn’t stopped many celebrities from happily wearing glasses even if they do not need them. Justin Bieber is just one high-profile fan of fashion glasses.1. What does the new study show?A. People wearing glasses are smarter.B. People wearing glasses are healthier.C. Wearing glasses can make people cleverer.D. Wearing glasses is associated with higher IQ.2. What does the underlined word in Paragraph 3 mean?A. Shift.B. Link.C. Proof.D. Consequence.3. Why do some lawyers ask their clients to wear glasses in court?A. Because it can create a moral image.B. Because it can mislead the witnesses.C. Becau se it can highlight clients’ qualities.D. Because it can prove the clients’ innocence.4. What is the general attitude to those who wear glasses for fashion?A. Positive.B. Negative.C. MixedD.

To win, they had to finish the 142-mile race in less than 10 hours. Teams and watchers knew theremight be no winner at all, because these vehicles were missing a key part－drivers.DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The “winner,” if there was any, reached 7.8 miles before it ran into a lo ng, narrow hole, and the front wheels caught on fire.“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. “Even ants (蚂蚁) can do all these tasks effortlessly. It’s very hard for us to put these abilities into our machines.”The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately. Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.1. Watchers doubted if any of the vehicles could finish the race because_____.A. they did not have any human guidanceB. the road was not familiar to the driversC. the distance was too long for the vehiclesD. the prize money was unattractive to the drivers2. DARPA organized the race in order to_____.A. raise money for producing more robotic vehiclesB. push the development of vehicle industryC. train more people to drive in the desertD. improve the vehicles for future wars3. From the passage we know “robotic vehicles” are a kind of machines that _____.A. can do effortlessly whatever tasks living thing canB. can take part in a race across 142 miles with a time limitC. can show off their ability to turn themselves upside downD. can move from place to place without being driven by human beings4. In the last paragraph, the writer implies that there is a long way to go______.A. for a robotic vehicle to finish a 142-mile race without any difficultiesB. for a little child who has just learned to walk to reach the cookie on the tableC. for a robotic vehicle to deal with a simple problem that a little child can solveD. for a little child to understand the importance of wiping apple juice off its face阅读理解说明文【都选C】备战2020年高考英语之新试题抢先练练母题，选对C（建议用时15分钟）A（2019·全国I卷，C）As 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.

2020高考英语专题01阅读理解之说明文【2020年】1.（2020·新课标Ⅰ）BReturning to a book you’ve read many times can feel like drinks with an old friend. There’s a welcome familiarity - but also sometimes a slight suspicion that time has changed you both, and thus the relationship. But books don’t change, people do. And that’s what makes the act of rereading so rich and transformative.The beauty of rereading lies in the idea that our bond with the work is based on our present mental register. It’s true, the older I get, the more I feel time has wings. But with reading, it’s all about the present. It’s about the now and what one contributes to the now, because reading is a give and take between author and reader. Each has to pull their own weight.There are three books I reread annu ally The first, which I take to reading every spring is Emest Hemningway’s A Moveable Feast. Published in 1964, it’s his classic memoir of 1920s Paris. The language is almost intoxicating (令人陶醉的)，an aging writer looking back on an ambitious yet simpler tim e. Another is Annie Dillard’s Holy the Firm, her poetic 1975 ramble (随笔) about everything and nothing. The third book is Julio Cortazar’s Save Twilight: Selected Poems, because poetry. And because Cortazar.While I tend to buy a lot of books, these three were given to me as gifs, which might add to the meaning I attach to them. But I imagine that, while money is indeed wonderful and necessary, rereading an author’s work is the highest currency a reader can pay them.

It does, however, have its own problem.Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the50-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 takessome 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.3.（2020·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’re short of water and a plant that can detect harmfu l 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?4.（2020·新课标Ⅱ）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 4 later develop better spatial skills. Puzzle play was found to be a significant predictor of cognition(认知) after controlling for differences in paren ts’ income, education and the amount of parent talk, Levine said.The researchers analyzed video recordings of 53 child-parent pairs during everyday activities at home and found children who play with puzzles between 26 and 46 months of age have better spatial skills when assessed at 54 months of age.“The children who played with puzzles performed better than those who did not, on tasks that assessed their ability to rotate(旋转)and translate shapes,” Levine said in a statement.The parents were asked to interact with their children as they normally would, and about half of children in the study played with puzzles at one time. Higher-income parents tended to have children play with puzzles more frequently, and both boys and girls who played with puzzles had better spatial skills. However, boys tended to play with more complex puzzles than girls, and the parents of boys provided more spatial language and were more active during puzzle play than parents of girls.The findings were published in the journal Developmental Science.24. In which aspect do children benefit from puzzle play?A. Building confidence.B. Developing spatial skills.C. Learning self-control.D. Gaining high-tech knowledge.25. What did Levine take into consideration when designing her experiment？A. Parents’ age.B. Children’s imagination.C. Parents’ education.D. Child-parent relationship.26. How do boy differ from girls in puzzle play?A. They play with puzzles more often.B. They tend to talk less during the game.C. They prefer to use more spatial language.D. They are likely to play with tougher puzzles.27. What is the text mainly about?A. A mathematical method.B. A scientific study.C. A woman psychologistD. A teaching program.5.（2020·新课标Ⅱ）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 d own 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-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. She trying to come up with a lable to attach to nutria fashions to show it iseco-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 abouf wearing fur in New York according to Morgan?A. It’s formal.B. It’s risky.C. It’s harmful.D. It’s traditional.6.（2020·新课标Ⅲ）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 recen t 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.”In201, 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 rivers.C. 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 Divers7.（2020·江苏卷）BSometimes it’s hard to let go. For many British people, that can apply to institutions and objects that represent their c ountry’s past-age-old castles, splendid homes… and red phone boxes.Beaten first by the march of technology and lately by the terrible weather in junkyards (废品场), the phone boxes representative of an age are now making something of a comeback. Adapted in imaginative ways, many have reappeared on city streets and village greens housing tiny cafes, cellphone repair shops or even defibrillator machines (除颤器).The original iron boxes with the round roofs first appeared in 1926. They were designed by Giles Gilbert Scott, the architect of the Battersea Power Station in London. After becoming an important part of many British streets, the phone boxes began disappearing in the 1980s, with the rise of the mobile phone sending most of them away to the junkyards.About that time, Tony Inglis’ engineering and transport company got the job to remove phone boxes from the streets and sell them out. But Inglis ended up buying hundreds of them himself, with the idea of repairing and selling them. He said that he had heard the calls to preserve the boxes and had seen how some of them were listed as historic buildings.As Inglis and, later other businessmen, got to work, repurposed phone boxes began reappearing in cities and villages as people found new uses for them. Today, they are once again a familiar sight, playing roles that are oftenjust as important for the community as their original purpose.In rural areas, where ambulances can take a relatively long time to arrive, the phone boxes have taken on a lifesaving role. Local organizations can adopt them for l pound, and install defibrillators to help in emergencies.Others also looked at the phone boxes and saw business opportunities. LoveFone, a company that advocates repairing cellphones rather than abandoning them, opened a mini workshop in a London phone box in 2016.The tiny shops made economic sense, according to Robert Kerr, a founder of LoveFone. He said that one of the boxes generated around $13,500 in revenue a month and cost only about $400 to rent.Inglis said pho ne boxes called to mind an age when things were built to last. I “like what they are to people, and I enjoy bringing things back,” he said.58. The phone boxes are making a comeback ______.A. to form a beautiful sight of the cityB. to improve telecommunications servicesC. to remind people of a historical periodD. to meet the requirement of green economy59. Why did the phone boxes begin to go out of service in the 1980s?A. They were not well-designed.B. They provided bad services.C. They had too short a history.D. They lost to new technologies.60. The phone boxes are becoming popular mainly because of ______.A. their new appearance and lower pricesB. the push of the local organizationsC. their changed roles and functionsD. the big funding of the businessmen8.（2020·江苏卷）CFor those who can stomach it, working out before breakfast may be more beneficial for health than eating first, according to a study of meal timing and physical activity. Athletes and scientists have long known that meal timing affects performance. However,far less has been known about how meal timing and exercise might affect general health.To find out, British scientists conducted a study. They first found 10 overweight and inactive but otherwise healthy young men, whose lifestyles are, for better and worse, representative of those of most of us. They tested the men’s fitness and resting metabolic (新陈代谢的) rates and took samples (样品) of their blood and fat tissue.Then, on two separate morning visits to the scientists’ lab, each man walked for an hour at an average speedthat, in theory should allow his body to rely mainly on fat for fuel. Before one of these workouts, the men skipped breakfast, meaning that they exercised on a completely empty stomach after a long overnight fast (禁食). On the other occasion, they ate a rich morning meal about two hours before they started walking.Just before and an hour after each workout, the scientists took additional samples of the men’s blood and fat tissue.Then they compared the samples. There were considerable differences. Most obviously, the men displayed lower blood sugar levels at the start of their workouts when they had skipped breakfast than when they had eaten. As a result, they burned more fat during walks on an empty stomach than when they had eaten first. On the other hand, they burned slightly more calories (卡路里), on average, during the workout after breakfast than after fasting.But it was the effects deep within the fat cells that may have been the most significant, the researchers found. Multiple genes behaved differently, depending on whether someone had eaten or not before walking. Many of these genes produce proteins (蛋白质) that can improve blood sugar regulation and insulin (胰岛素) levels throughout the body and so are associated with improved metabolic health. These genes were much more active when the men had fasted before exercise than when they had breakfasted.The implication of these results is that to gain the greatest health benefits from exercise, it may be wise to skip eating first.61. The underlined expression “stomach it” in Paragraph 1 most probably means “______”.A. digest the meal easilyB. manage without breakfastC. decide wisely what to eatD. eat whatever is offered62. Why were the 10 people chosen for the experiment?A. Their lifestyles were typical of ordinary people.B. Their lack of exercise led to overweight.C. They could walk at an average speed.D. They had slow metabolic rates.63. What happened to those who ate breakfast before exercise?A. They successfully lost weight.B. They consumed a bit more calories.C. They burned more fat on average.D. They displayed higher insulin levels.64. What could be learned from the research?A. A workout after breakfast improves gene performances.B. Too much workout often slows metabolic rates.C. Lifestyle is not as important as morning exercise.D. Physical exercise before breakfast is better for health.9.（2020·山东卷）DAccording to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.To test the effect of social influence on eating habits,the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?12. What is the recent study mainly about?A. Food safety.B. Movie viewership.C. Consumer demand.D. Eating behavior.13. What does the underlined word “beanpoles” in paragraph 1 refer to?A. Big eaters.B. Overweight persons.C. Picky eaters.D. Tall thin persons.14. Why did the researchers hire the actor?A. To see how she would affect the participants.B. To test if the participants could recognize her.C. To find out what she would do in the two tests.D. To study why she could keep her weight down.15. On what basis do we “adjust the influence” according to the l ast paragraph?A. How hungry we are.B. How slim we want to be.C. How we perceive others.D. How we feel about the food.10.（2020·天津卷）AHow to Use a Modern Public LibraryHas it been a while since your last visit to a public library? If so, you may be surprised to learn that libraries have changed for the better. It’s been years since they were dusty little rooms with books. They have transformed themselves into places where you can develop your love of knowledge meet interesting people, or find out how to start a business.Check out a book. While libraries still loan out(出借)books, you’ll find it easier to get a copy of whatever you’re looking for, thanks to a cooperative network of area libraries. Via such networks, libraries share their books with each ot her through the use of delivery vehicles. Once the book you’ve requested is delivered to the nearest branch, they will inform you by e-mail, so you can pick it up.Check out other items. The library is now a multimedia zone, loaded with information in many formats(载体形式). You can borrow movies on DVDs, music on CDs, and popular magazines. Some libraries even loan out toys and games. If a popular magazine you want isn’t offered and the library keeps a list of such requests, they may bring it in when enough interest is shown.Join targeted reading groups. Libraries will often hold reading-group sessions targeted to various age groups. Perhaps you’d like to learn a language or improve your English. The library may sponsor a language group you could join. If you have difficulties reading, ask about special reading opportunities. Your library might be able to accommodate you. And you might find it relaxing to bring your small kid to a half-hour Story Time while you sit quietly in a corner with a good book.Start a business using the help of your local library. If you want to have a business of your own, your locallibrary can become a launch space for it. In library books and computers, you can find information on starting a business. Many libraries will help you with locally supplied information about business management shared through chambers of commerce(商会)and government agencies, and they will offer printing, faxing and database services you need.36. Public libraries connected by a cooperative network benefit readers by______.A. sharing their books on the InternetB. giving access to online reading at a library branchC. sending a needed book to a library branch nearbyD. making the checkout procedures diverse37. According to Paragraph 3, what items may be checked out from a public library?A. A magazine and an e-book.B. A game and an oil painting.C. A music CD and a kid’s toy.D. A DVD and a video player38. As is described in Paragraph 4, taking a small kid to a half-hour Story Time allows ______.A. the kid to learn a new languageB. the parent to enjoy quiet readingC. the kid to overcome reading difficultiesD. the parent to meet their program sponsor39. Your local library can help you start a business by ______.A. providing relevant information and supporting servicesB. offering professional advice on business managementC. supplying useful information of your potential buyersD. arranging meetings with government officials40. What is the purpose of the passage?A. To point out the importance of public libraries.B. To encourage people to work in public libraries.C. To introduce the improved services of public libraries.D. To call for the modernization of public library systems.11.（2020·天津卷）CFor people, who are interested in sound, the field of sound technology is definitely making noise. In the past, sound engineers worked in the back rooms of recording studios, but many of today’s sound professionals are sharing their knowledge and experience with professionals in other fields to create new products based on the phenomenon we call sound.Sound can be used as a weapon. Imagine that a police officer is chasing a thief. The thief tries to escape. And the officer can’t let him get away. He pulls out a special device, points it at the suspect, and switc hes it on. The thief drops to the ground. This new weapon is called a Long Range Acoustic Device(LRAD, 远程定向声波发射器). It produces a deafening sound so painful that it temporarily disables a person. The noise from the LRAD is directed like a ray of light and travels only into the ears of that person, but it is not deadly.For those who hunger for some peace and quiet, sound can now create silence. Let’s say you are at the airport, and the little boy on the seat next to you is humming(哼唱) a short commercial song. He hums it over and over again, and you are about to go crazy. Thanks to the Silence Machine, a British invention, you can get rid of the sound without upsetting the boy or his parents. One may wonder how the Silence Machine works. Well, it functions by analyzing the waves of the incoming sound and creating a second set of outgoing waves. The two sets of waves cancel each other out. Simply turn the machine or point it at the target, and your peace and quiet comes back.Directed sound is a new technology that allows companies to use sound in much the same way spotlights(聚光灯) are used in the theater. A spotlight lights up only one section of a stage; similarly, “spotsound” creates a circle of sound in on targeted area. This can be useful for businesses such as restaurants and stores because it offers a new way to attract customers. Restaurants can offer a choice of music along with the various food choices on the menu, allowing customers more control over the atmosphere in which they are dining. Directed sound is also beginning to appear in shopping centers and even at homes.46. What could be inferred from Paragraph 2 about the effect of the LRAD?A. It causes temporary hearing loss.B. It slows down a running man.C. It makes it easy to identify a suspect.D. It keeps the suspect from hurting others.47. The Silence Machine is a device specially designed to ________.A. silence the people around you。

2020年高考英语说明文阅读读理解专练1.阅读理解Researchers around the world have been trying their hand at making better use of the huge amount of wind energy available in nature to produce clean energy. Apart from this, studies are being carried out to harness(利用) usable windenergy produced by man-made technologies.One useful source identified by Indian inventor Santosh Pradhan about two years ago is a speeding train, which produces fierce wind that can betrans formed into electricity.According to Pradhan's proposal, with a few small improvements in existing trains running in Mumbai, the largest city in India, at least 10,000 megawatts(兆瓦) of electricity could be harvested each day.Building on this principle, designers Ale Leonetti Luparinia and Qian Jiang from Yanko Design have created a device(装置) called T-Box that harnesses wind energy from speeding trains.T-Box can be placed within the railway tracks. It is half-buried underground between the concrete sleepers(水泥枕木), which does not disturb the normal train operating at all. According to Yanko, around 150T-Boxes can be fitted along a 1,000-meter railway track.A train running at a speed of 200 kph can produce winds blowing at 15 miles a second. Based on this calculation, 150 T-Boxes can produce 2.6 KWH of electricity per day. The T-Box's design won a silver medal in last year's Lite-On Awards and was exhibited last summer at the Xue Xue Institute inTaipei, Taiwan Province.Though the figures look impressive, it is important to remember that the design is still at a conceptual stage and hasn't taken into account issues such as pieces of waste material produced by the device and the efforts and costs involved in the maintenance(维护) of the device.We can expect the technology to see the light of the day only after it clears these issues. If so, rail travel, one of the greenest forms of travel, will become greener and more energy-efficient.（1）What can we learn about T-Box?A. It will be fitted on the trains.B. It is based on Pradhan's idea.C. It can turn electricity into light.D. It was invented by an Indian scientist.（2）How much electricity can be produced per day by T-Boxes along a railway track of 100km?A. 260 KWHB. 2.6 KWHC. 150 KWHD. 1.5 KWH（3）It can be concluded from the last two paragraphs that ______.A. T-Box has proved to be effective in harvesting windB. the maintenance of T-Box will be costlyC. there is much to do about T-BoxD. T-Box will come into use soon（4）According to the passage, which of the following statements is TRUE?A. The Indian inventor Santosh Pradhan invented the speeding train.B. The T-Box's design won a silver medal in Lite-On Awards last year.C. Rail travel has become one of the energy-efficient technologies in the world.D. The India harvests 10,000 megawatts of electricity each day on average.（5）The passage is mainly written to _______.A. encourage more people to travel by trainB. explain the advantages of electricityC. tell readers how to save energy and moneyD. introduce a new invention to readers2.阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。

考点17 阅读理解之说明文〔2020 • 全国卷I，C〕Race 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.A 篇〔2020 •全国卷1 D〕The 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 furtherchanging 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 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?B 篇〔2019 •全国卷2〕Marian Bechtel sits at West Palm Beach’s Bar Louie counter by herself, quietly reading her e-book as she waits for her salad. What is she reading? None of your business! Lunch is Bechtel’s “me〞time. And like more Americans, she’s no t alone.A new report found 46 percent of meals are eaten alone in America. More than half(53 percent) have breakfast alone and nearly half(46 percent) have lunch by themselves. Only at dinnertime are we eating together anymore, 74 percent, according to statistics from the report.“I prefer to go out and be out. Alone, but together, you know?〞 Bechtel said, looking up from her book. Bechtel, who works in downtown West Palm Beach, has lunch with coworkers sometimes, but like many of us, too often works through lunch at her desk. A lunchtime escape allows her to keep a boss from tapping her on the shoulder. She returns to work feeling energized. “Today, I just wanted some time to myself,〞 she said.Just two seats over, Andrew Mazoleny, a local videographer, is finishing his lunch at the bar. He likes that he can sit and check his phone in peace or chat up the barkeeper with whom he’s on a first-name basis if he wants to have a little interaction(交流). “I reflect on how my day’s gone and think about the rest of t he week,〞he said. “It’s a chance for self-reflection. You return to work recharged and with a plan.〞That freedom to choose is one reason more people like to eat alone. There was a time when people may have felt awkward about asking for a table for one, but those days are over. Now, we have our smartphones to keep us company at the table. “It doesn’t feel as alone as it may have before all the advances in technology,〞 said Laurie Demeritt, whose company provided the statistics for the report.24．What are the statistics in paragraph 2 about?A．Food variety.B．Eating habits.C．Table manners.D．Restaurant service.25．Why does Bechtel prefer to go out for lunch?A．To meet with her coworkers.B．To catch up with her work.C．To have some time on her own.D．To collect data for her report.26．What do we know about Mazoleny?A．He makes videos for the bar.B．He’s fond of the food at the bar.C．He interviews customers at the bar.D．He’s familiar with the barkeeper.27．What is the text mainly about?A．The trend of having meals alone.B．The importance of self-reflection.C．The stress from working overtime.D．The advantage of wireless technology.A 篇〔〔2020·某某高三二模〕Addiction is a term that we hear all the time but it’s a surprisingly tricky concept to pin down. Orally, we might say things like: “Oh, I downloaded this new game on my phone and I’m totally addicted to it.〞 But from a clinical perspective, we think of addiction as occurring when someone has found that their life whether it’s’ their relationships with friends or famil y,their ability to perform their jobs, or something else has been knocked off-kilter (冲昏头脑) by desire to perform behavior.Prof Robert West, editor-in-chief of the journal Addiction, defines addiction “a psychological condition that involves repeated powe rful motivation to engage in a behavior that’s learnt through experience, and that has either actual or potential harmful consequences〞. Under this definition, it is possible to be addicted to anything—not just substances—if it turns from a want for it to a need for it, and it puts a person at risk of harm.In 2008, Bowden-Jones set up the National Problem Gambling Clinic. To date, this is the only NHS-funded treatment center for people with problem gambling (赌博). Despite seeing some of the most severe cases of gambling addiction in the country in her clinic, she is keen to point out that the scale of the problem might not be as extreme as some would think. Despite lots of people gambling and the pervasive (遍布的) nature of gambling advertising, problem gamblers make up less than one per cent of the population.Yet she wonders whether there is something about how modern technology has become increasingly risky. “The more you have availability, the more you uncover vulnerability,〞 she says. And there’s concern a mong researchers from several different countries that online games and apps are taking inspiration from gambling to keep people playing, and paying. These include what are known as “loot boxes〞. These are prizes, paid for with real money, where the contents are not known until they’re purchased. Recent research has suggested purchase of these prizes is linked to higher levels of problematic gambling behavior.However, Bowden-Jones points out that technological advances have also improved support for some people with problematic gambling. Software now exists to block gambling-related websites across people’s devices. Banking apps can allow a person to disable any ability to spend money on gambling, cautiously, by just toggling (切换) a switch. She believes that this is a big step forward -historically people were encouraged to hand their finances to their partners. This can put pressure on relationships and there is strong evidence to show it can increase domestic violence.It’s hard to tell addiction is on the increase, partly because as yet there aren’t standardized measures by which to assess things like problematic gaming, and large-scale surveys have not been done. But just because we might see people glued to their phones while they’re on buses or trains o r while walking down the street, it doesn’t mean we’ve become nation who are addicted to the Internet.Nonetheless, in 2018 the World Health Organization announced that it was classifying gaming disorder as a mental health condition, decision they based on a review of the evidence and after discussion with experts. However, some researchers worry that this classification will lead to overdiagnosis of gaming The NHS does not offer treatment for gaming disorder, and a pilot treatment clinic has been delayed. It’s clear that we know very little about how many people have gaming disorder, and it’s likely that the vast majority of people who play games do so with no harm to their health whatsoever. Having said that, for those who are worried, it is possible to spot the warning signs of pleasurable activity becoming compulsion (强迫力), either in yourself or in those around you.Robert West has some final words of advice for those individuals who are trying to reduce their need for a behavior. “Self-control is much easier when you set fixed boundaries than when you leave the rules more flexible,〞he explains. Be strict with yourself and don’t allow your boundaries to slide, then even if you do slip up, you can get back on track.1．What is addiction according to the first two paragraphs?A．It is a repeated desire to perform a behavior.B．It is a physical and mental condition.C．It is a habit of downloading new games.D．It is the direct result of carelessness.2．What does Bowden-Jones think of gambling addiction?A．It is affected by gambling advertising.B．Its scale is small and fewer people develop it.C．It can be treated in a NHS-funded center.D．Its severity is beyond imagination of some people.3．What does the underlined sentence in Paragraph 4 mean?A．Online apps take inspiration from gambling.B．More prizes lead to more gambling behavior.C．More money brings more prizes in loot boxes.D．Too much use of technology brings more risk.4．What do technological advances in Paragraph 5 indicate?A．Banking apps are popular among banks.B．They can increase domestic violence.C．They can bring about positive results.D．Software can block gambling-related websites.5．Why do researchers worry about the classification of gaming disorder?A．Playing games do no harm to lot of people.B．We’ve become a nation addicted to the internet.C．It isn’t scientific and may lead to wrong diagnosis.D．A pleasant activity may become a strong force.6．What does the passage mainly talk about?A．Is addiction on the rise? B．How addiction is defined?C．Is Robert West’s advice reasonable?D．What is Bowden Jones’s research?B 篇〔2020·河北省高三三模〕As one of the most important languages in the world, Latin had humble beginnings. It originated along the Tiber River in Italy and only a handful of people spoke the language. Over time, Latin became more well-known as Romans gained political power. Many famous literary texts and scientific classifications were written in Latin. Even though knowing Latin indicated a person was educated, according to Britannica, in the 20th century far fewer people learned Latin, leading it to be classified as a “dead〞 language.There are around 7,000 living languages in the world, but, according to Britannica, “morethan half are at risk of dying out by the end of the 21st century.〞 Civilizations evolve over time and so do languages. More often than not, a language dies because everyone who speaks the language dies. For example, Marie Smith Jones, perhaps the last native speaker of the Alaskan Eyak language, died at the age of 89 in 2008, and so did the language. Now, fewer and fewer people speak Latin, which raises public’s awareness about its protection.Actually, there are many other reasons as to why Latin should be protected or taught. “It is a window into a fascinating ancient civilization, and studying an ancient civilization teaches us to respect different points of view and unfamiliar cultural practices,〞 says Kathleen Coleman, James Loeb Professor of Harvard University.Since it isn’t used in ordinary conversations, there are a lot of difficulties that arise from teaching Latin. “Teaching a ‘dead’ language is different from teaching other languages,〞explains Coleman, “because there are no native speakers to show us how it sounds or answer questions about the meaning of words or expl ain idioms. Though it’s hard, fortunately, we still can find the answers to our questions from the broken evidence available in written texts.〞7．What can we learn about Latin from Paragraph 1?A．Most people didn’t learn Latin in the 20th century.B．Only educated people learned Latin in the past.C．Latin was not favored by scientists and writers.D．Latin was well-known since its birth.8．The author mentions Marie Smith Jones in Paragraph 2 to show ________.A．how a language diesB．what a dead language isC．how a language is protectedD．who is the last Alaskan Eyak speaker9．Why should people learn Latin according to Coleman?A．To show unfamiliar practices. B．To respect others’ opinions.C．To protect a “dead〞 language. D．To learn about an ancient society.10．What will the author probably discuss in the following paragraph?A．The learning methods. B．The development of Latin.C．The learning materials. D．The difficulties in learning Latin.考点练【答案】28. C 29. D 30. A 31. B【解析】这是一篇说明文。
