Throughout much of human history, man has been the measure of many, if not all, things. Lengths were divided up into feet and smaller units from the human hand. Other measures were equally characteristic. Mediterranean traders for centuries used the weight of grains of wheat to define (定义) their units of mass. The Romans used libra, forerunner of the pound, by referring to the weight of a carob (角豆树) seed.The sizes of similarly named units could also differ. The king's foot, used in France for nearly 1, 000 years after its introduction by Charlemagne in around 790 AD, was, at 32.5cm, around a centimeter shorter than the Belgic foot, used in England until 1300.Greek, Egyptian and Babylonian versions of water in a fixed container varied from one another by a few kilos, Nor was there agreement on such things within countries. In France, where there was no unified (统一的) measurement system at the national level, the situation was particularly terrible. The lieue (former measure of distance), for example, varied from just over 3 km in the north to nearly 6 km in the south.Although John Wilkins, an Englishman, first put forward a decimal system (十进制) of measurement in 1668, it was the French who in 1799 made it law. The Système International d'Unités (SI, or the metric system, as it is better known) developed from it and became the official measurement in all countries except Myanmar, Liberia and the United States. Now the International Bureau of Weights and Measures in Paris is set to give the metric system its biggest shake-up yet.At a meeting in Versailles, France, on November 16th, 2018, the world's measurement bodies are almost certain to approve a decision that will mean four out of the seven base SI units, including the kilogram, will follow the other three, including the metre, in being redefined in terms of the values of physical constants (物理常数).Each of the chosen constants has been measured incredibly precisely, which would mean that from May 20th2019 the constants will themselves be fixed at their current values for ever. Any laboratory in the world will then be able to measure, for example, the mass of an object as precisely as the accuracy of their equipment will allow.（1）What does Paragraph 1 mainly tell us?A.Pound went before libra in measurement.B.Different things used to be adopted as measures.C.Grains were accepted as measures by the Romans.D.Fixed measurement systems were gradually formed.（2）How does the author develop the second paragraph?A.In time order.B.By analysis.C.In space order.D.By comparison.（3）Which of the following countries used SI as an official measurement?A.France.B.Liberia.C.America.D.Myanmar.（4）What will the world's measurement bodies achieve at the meeting held in Versailles?A.They will come up with seven new SI units.B.They will set May 20th as a new international festival.C.They will redefine four SI units including the kilogram.D.They will decide on a new measure used in the laboratory.【答案】（1）B（2）D（3）A（4）C【解析】【分析】本文是一篇说明文，法国凡尔赛宫举办的国际计量大会，将对目前使用的国际单位制中的四个基本单位进行重新定义，其中包括对千克的重新定义。

Moving in with a boyfriend causes women to eat more unhealthily and put on weight. But the opposite is true for men, whose long-term health benefits when they move in with a female partner.Dieticians at Newcastle University said both partners try to please one another, and so change their dietary habits to suit their other half.It leads men to eat more light meals, such as salads, fruit and vegetables, while women choose to make creamier, heavier dishes curry or rich pasta sauces, which may please their partner. Women still have the strongest long-term influence over the couple's diet and lifestyle, as they still have the traditional role of shopper and cook in most households.The report, by Newcastle University's Human Nutrition Research Centre, reviewed the finding of a variety of research projects from the UK, North America and Australia, which looked at the eating and lifestyle habits of couples.The research shows that women are more likely to put on weight and increase their consumption of foods high in fat and sugar when they move in with their partnerWomen also use food as a comfort when dealing with emotional stress and have been found to gain weight when a relationship ends, while the same finding has not been observed in men.Many couples reported food as being central to their partnership, and eating together in the evening was particularly important to many.Report author and registered dietician Dr. Amelia Lake said, "The research has shown that your partner is a strong influence on lifestyle and people who are trying to live healthier lives should take this factor into consideration."（1）According to the passage, moving in with a girlfriend, men ________.A. have few changes of their dietary habitsB. have to eat more unhealthy foodsC. don't like foods high in fat and sugar at allD. try to eat foods that their girlfriends like（2）The underlined word "light" (in Paragraph 4) probably means ________.A. not very heavyB. less in fat and sugarC. gentleD. not serious or important （3）According to the report by Newcastle University's Human Nutrition Research Centre, ________.A. women put on weight only because they want to suit their other halfB. when men are faced with emotional stress, they will change their dietary habitsC. eating together in the evening is a good way to communicate for couplesD. it is wrong to change your dietary habits to suit your partner（4）From the passage, we can infer that ________.A. women should pay more attention to their partner's influence on themB. more men will play roles of shopper and cook in most householdsC. couples will not change their dietary habits and lifestyle to please their partnerD. long-term health of men benefits when they move in with a female partner（5）What would be the best title for the passage?A.

Supercomputers which can analyse blood samples and predict which patients are likely to become seriously ill could save tens of thousands of lives a year, it was revealed last night, according to The Daily Express.The artificial intelligence (AI) system, developed at University College London and set to be piloted in NHS hospitals later this year, will screen "at risk" patients so doctors can take early action to prevent death or serious illness. Prof Young, a consultant surgeon at Southend University Hospital, said: "I am so excited about this form of technology." Instead of people getting sick or dying because they are not picked up in time, this will allow us to step in earlier which will save lives and an enormous amount of money. "I think the potential of AI in healthcare like this is as big as the Industrial Revolution was—and signals a completely new example in the way we manage healthcare."The technology is the brainchild of Dr Vishal Nangalia, a consultant at the Royal Free Hospital in London. He used AI to analyse a billion stored blood samples from 20 different UK hospital trusts dating back up to 12 years. Computers assess blood test results by picking up subtle changes in red and white blood cells, suggesting a patient is going downhill.He found the technique forecast outcomes of patients with kidney problems with up to 95 per cent accuracy. Traditional methods highlighting serious patient concerns picked up as few as 16 percent of patients who went on to die. "This gives us the opportunity not only to save lives but to prevent serious illness, making the health service not only safer but more efficient." Prof Young said, "Instead of waiting for people to get worse, we will be able to treat them earlier."（1）What does the underlined phrase "screen" in Paragraph2 mean?A. comfortB. treatC. spotD. nurse（2）How do supercomputers help save lives?A. By storing blood samples.B. By analyzing patients' cases.C. By observing changes in blood cells.D. By assisting doctors with their operations.（3）Why did Professor Young mention the Industrial Revolution?A. To show the influence of AI.B. To stress the importance of health care.C. To introduce the topic of supercomputers.D. To present the achievement he has accomplished.（4）What do we know about the new technology?A. It helps patients recover earlier.B. It has helped save thousands of lives.C. It will promote the health service greatly.D. It is intended for patients with kidney diseases.【答案】（1）C（2）C（3）A（4）C【解析】【分析】本文是一篇说明文，介绍超级计算机能够分析血样并预测哪些病人可能会患上重病，每年可以挽救数万人的生命。

The clock always seems to be ticking rather too fast in the doctor's office and the queue of patients outside the door seems to be pressing rather too hard. Some say it's high time for the model of short, sharp one-to-one appointments to give way to shared medical appointments (SMAs共享医疗预约).SMAs are doctor-patient visits in which a group of patients receive patient education and counseling (咨询), physical examination and medical support in a group setting. Typically SMAs are designed to have one or more doctors attend to a group of patients who share a common illness or medical condition. In contrast to one-to-one visits, SMAS provide a longer appointment time-frame as well as the opportunity for patients to have improved access to their physicians and meanwhile pick up additional information and support from peers.However, doctors who have pioneered the shared appointment approach report that there are significant challenges involved. Dr. Sumego, director of shared medical appointments, Cleveland Clinic, identifies culture change as the most significant challenge. Physicians and nurses are trained in a model of personal service and privacy; the SMA approach is a fundamental challenge to those fixed ideas. They need shared goals and a way of testing the innovation against agreed standards. Dr. Sumego says, "The physicians may be worried about the possible chaos and efficiencies that are marketed. They also have to make the patients understand what their appointment is, and what the expectation is.""So, if an organization was looking to start shared medical appointments, I would advise them to start the buy-in from a few champion physicians, develop the work-flow and develop some experience. Provide some support behind what that best practice should look like. Create some standards so that, as the concept spreads, you can employ that experience to start the next shared medical appointments and the next."（1）What is the purpose of the SMA approach?A. To improve medical service.B. To promote doctors' reputation.C. To conduct medical research.D. To meet patients' expectation.（2）According to Dr. Sumego, what prevents the SMA approach from being widely adopted?A. Personal service.B. Fixed ideas.C. Lack of equipment.D. Shared goals.（3）What can the underlined "buy-in" in Paragraph 4 be replaced by?A. practiceB. organizationC. purchaseD. support（4）What can be learned about the SMA approach in the last paragraph?A. It is currently being questioned.B. It is impractical in some areas.C. It will enjoy wide popularity soon.D. It should be carried out step by step.【答案】（1）A（2）B（3）A（4）D【解析】【分析】本文是一篇说明文，介绍了SMAs (共享医疗预约) 模式，以及这种模式面临的挑战。

An international team of researchers from the University of Oxford have found that the way people use the Internet is closely tied to the seasonal movements in thenatural world. Their online species searches follow the patterns of seasonal animal migrations （迁徙）.Migratory birds （候鸟） flood back to where they reproduce every spring. That migratory behavior is accompanied by some human behavior. "In English-language Wikipedia （维基百科）, the online searches for migratory species tend to increase in spring when those birds arrive in the United States," said the lead author John Mittermeier.And not just birds. Mittermeier and his team surveyed nearly 2.5 billion Wikipedia search records, for 32,000 species, across 245 languages. They also saw variable search rates for insects, horsetails and flowering plants. Seasonal trends seemed to be widespread in Wikipedia behavior for many species of plants and animals.This finding suggests new ways to monitor changes in the world's biological diversity. It also shows new ways to see how much people care about nature, and which species and areas might be the most effective targets for conservation.Mittermeier is encouraged by the search results. He commented, "I think there's a concern among conservationists （生态环境保护者） that people are losing touch with the natural world and that they're not interacting with native species anymore. And so in that sense, it was really exciting and quite unexpected for me to see people's Wikipedia interest closely related to changes in nature."Richard Grenyer, Associate Professor from the University of Oxford, says search data is useful to conservation biologists, "By using these big data approaches, we candirect our attention towards the difficult questions in modern conservation: which species and areas are changing, and where are the people who care the most and can do the most to help."（1）What have researchers found about species searches?A.They strengthen ties among people.B.They affect the animal movements.C.They differ in language backgrounds.D.They reflect animal migration seasons.（2）What is the purpose of writing Paragraph 3?A.To summarize the research process.B.To further support the research findings.C.To show the variety of species searches.D.To present researchers' heavy work load.（3）How does Mittermeier feel about the search results?A.Satisfied with Wikipedia's service.B.Worried about Wikipedia behavior.C.Amazed at people's care about nature.D.Sad about people's not getting close to nature.（4）Why does Richard think such search data is useful?A.It helps to aim at conservation targets.B.It increases interest in big data approaches.C.It keeps track of trends in biologists' work.D.It pushes people to solve difficult problems.【答案】（1）D（2）B（3）C（4）A【解析】【分析】本文是一篇说明文，牛津大学的一个国际研究小组发现，人们使用互联网的方式与自然界的季节性运动密切相关。

While every dog owner knows their dogs can read their moods perfectly, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence.For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That's because the scientists believe humans show their emotions on their entire face.After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed.The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touch-screen models were all females, this confirmed what has been observed in previous studies dogs are more efficient at reading facial expressions of people that are the same gender as their owner.（1）How did the scientists conduct the experiment?A.By leaving dogs to women who are either happy or angry.B.By mixing the selected dogs together.C.By rewarding only half of the dogs touching the screenD.By showing digital pictures of women's happy or angry faces.（2）The underlined word "trepidation" in Paragraph 5 probably means ________.A.fear and hesitationB.curiosity and eagernessC.excitement and happinessD.doubt and sadness（3）According to the last paragraph, dogs with female owners ________.A.are fond of the male facesB.are uninterested in telling the emotions on the entire facesC.have difficulty telling the moods on the faces of malesD.can only recognize emotions of females（4）What is the best title for this passage?A.Mood Changes Influence DogsB.Dogs Identify the MoodsC.dogs and Their OwnersD.Dog's Mood Research【答案】（1）D（2）A（3）C（4）B【解析】【分析】本文是一篇说明文，最新的实验发现，即狗能够识别人的面部表情的变化。

Robots are now being employed not just for dangerous tasks, such as discovering mines or rescuing people in disasters. They are also finding application as household helps and as nursing assistants. As increasing numbers of machines, equipped with the latest artificial intelligence, take on a growing variety of specialized and everyday tasks, the question of how people see them and behave towards them becomes ever more urgent.A team led by Sari Nijssen of Radboud University and Markus Paulus, Professor of Developmental Psychology at Ludwig-Maximilians-Universitaet (LMU), have carried out a study to determine the degree to which people show concern for robots and behave towards them based on moral principles.According to Sari Nijssen, the study set out to answer the following question:" Under what circumstances would adults be willing to sacrifice robots to save human lives?" The participants were faced with a hypothetical (假设的) moral dilemma: Would they be prepared to put a single person at risk in order to save a group of injured persons? In the situations presented the intended victim was either a human, a humanoid robot that had been humanized (人性化的) to various degrees or a robot that was clearly recognizable as a machine.The study suggested that the more the robot was humanized, the less likely participants were to sacrifice it. Situations that included vivid stories in which the robot was described as a merciful being or as a creature with its own understandings, experiences and thoughts, were more likely to stop the study participants from sacrificing it in the interests of anonymous (无名的) humans. "This result indicates that our study group attached a certain moral status to the robot," says Paulus. "One possible suggestion of this finding is that attempts to humanize robots should not go too far. Such efforts could come into conflict with their intended function—to be of help to us."（1）What has become a concern about robots?A. How to humanize them.B. How to treat them in life.C. How to use them effectively.D. How to find more applications.（2）In the study the participants probably have to decide ________.A. when to sacrifice a robotB. where to experience risksC. which robot to work withD. what robots should be like（3）What can be inferred from Paulus' words?A. Humanized robots offer less help to people.B. Humanizing robots too much may be improper.C. Certain moral status should be attached to robots.D. Conflicts often happen between humans and robots.（4）Which of the following would be the best title for the text?A. Robots, A Must for FutureB. Humanized Robots, A New TrendC. Robot Saved, People Take the HitD. Humanized Robots, Replace Human【答案】（1）B（2）A（3）B（4）C【解析】【分析】本文是一篇说明文，随着越来越多的机器人具有人性化，它们承担越来越多样化的专业和日常任务，人们如何看待他们，如何对待他们的问题变的迫在眉睫。

But for scientists, working out what is going on in an actor's head has always been something of a puzzle.Now, researchers have said actors show different patterns of brain activity depending on whether they are in character or not.Dr Steven Brown, from McMaster University in Canada, said, "It looks like when you are acting, you are suppressing （压制）yourself; almost like the character is possessing you."Brown and colleagues report how 15 actors, mainly theatre students, were trained to take on a Shakespeare role ——either Romeo or Juliet ——in a theatre workshop. They were then invited into the laboratory, where their brains were scanned in a series of experiments.Once inside the MRI scanner, the actors were asked to answer a number of questions, such as: would they go to the party? And would they tell their parents that they had fallen in love?Each actor was asked to respond to different questions, based on two different premises （前提）. In one, they were asked for their own perspective, while in the other, they were asked to respond as though they were either Romeo or Juliet.The results revealed that the brain activity differed depending on the situation being tested. The team found that when the actors were in character, they use some third-person knowledge or inferences about their character.The team said they also found additional reduction in activity in two regions of the prefrontal cortex （前额皮质）linked to the sense of self, compared with when the actors were responding as themselves.However, Philip Davis, a professor at the University of Liverpool, was unimpressed by the research, saying acting is about far more than "pretending" to be someone — it involves embodying （体现）the text and language.（1）How did Dr Brown's team conduct their research?A.By scanning the brain activity of some actors.B.By doing a survey with some theatre goers.C. By interviewing some theatre teachers.D. By consulting some experienced researchers.（2）What is the finding of Dr Brown's research?A.Acting is not as mysterious as people think.B.Actors' brain activity differs when they are acting.C.Acting is far more than pretending to be the character.D.Actors' brain activity is more active when they are in character.（3）How did Philip Davis react to the research?A. He supported it.B. He doubted it.C. He explained it.D. He advocated it.（4）What is the text mainly about?A. A debate of how the brain functions.B. A play written by Shakespeare.C.

A shark moving around the coastline is normally a worrying sight，but this waterborne drone (无人机) threatens floating rubbish instead of people.Developed by Dutch company RanMarine, the WasteShark takes nature as its inspiration with its whale shark-like mouth. Responsible for collecting waste, the drone will begin operations in Dubai Marina in November after a year of trials with local partner Ecocoast.According to RanMarine, the WasteShark is available in both autonomous and remote-controlled models. Measuring just over five feet by three-and-a-half feet (1.5 meters by 1.1 meter), it can carry up to 352 pounds of rubbish (159.6 kg) and has an operational battery life of 16 hours.By 2016 there were approximately 150 million tons of plastic in the world's oceans. One paper from December 2014 estimated that over a quarter of a million tons of ocean plastic pollution was afloat."WasteShark also has the abilities to gather air and water quality data, remove chemicals out of the water such as oil, and heavy metals, and scan the seabed to read its depth and outlines," said Oliver Cunningham, one of the co-founders of RanMarine. "Fitted with a collision-avoidance system, the drone uses laser imaging detection and ranging technology to detect an object in its path and stop or back up if the object approaches.""Our drones are designed to move through a water system, whether it's around the perimeter (周边) or through the city itself. The drones are that last line of defense between the city and the open ocean," added Cunningham. "WasteSharks are operating in Dubai, South Africa and the Netherlands and cost $ 17, 000 for the remote-controlled model and just under $ 23, 000 for the autonomous model."Dubai-based operator Ecocoast has two WasteShark drones. Co-founder Dana Liparts says they will clean waterfronts for clients including hotels and environmental authorities and that Ecocoast' intention is to have the collected rubbish recycled or upcycled. However, Liparts argues that cleaning waterways doesn't have a one-size-fits-all solution and requires a combination of new technology, preventative measures and changing people's attitudes towards littering.（1）What do we know about the WasteShark?A. It can frighten sharks away.B. It is an ocean explorer.C. It is a rubbish collector.D. It can catch fish instead of people.（2）What does Paragraph 4 mainly tell us?A. The causes of ocean pollution.B. The dangers of using plastics.C. The severity of ocean garbage pollution.D. The importance of ocean protection.（3）What will the WasteShark do with an approaching object?A. Avoid crashing into it.B. Break it into pieces.C. Swallow it.D. Fly over it.（4）Which of the following ideas does Liparts agree with?A. The WasteShark should be used more widely.B. More measures should be taken to make water clean.C. The production cost of WasteSharks should be reduced.D. People should take a positive attitude to new technology.【答案】（1）C（2）C（3）A（4）B【解析】【分析】本文是一篇说明文，介绍一种水上无人机可以用于清理浮在水面上的垃圾。

英语阅读理解(科普环保)练习题含答案含解析

英语阅读理解(科普环保)练习题含答案含解析一、高中英语阅读理解科普环保类1．犇犇阅读理解The Alexander techniqueUntil earlier this year, I didn't know anything about the Alexander technique—and saw no reason to think I should. One day, the backache I regularly suffered was more painful. I was brought up to think that the preferred way of dealing with aches is to do nothing and hope they'll go away, but I eventually went to the doctor. After examining me, he said, "You actually have bad posture (姿势). Go off and learn the Alexander technique." Three months later I could walk straighter and sit better.The Alexander technique is a way of learning how you can get rid of harmful tension in your body. The teaching focuses on the neck, head and back. It trains you to use your body less severely and carry out the movements that we do all the time with less effort. There is little effort in the lessons themselves, which sets apart the Alexander technique from yoga or pilates, which are exercise-based. A typical lesson involves standing in front of a chair and learning to sit and stand with minimum effort. You spend some time lying on a bench with your knees bent to straighten the spine (脊椎) and relax your body while the teacher moves your arms and legs to train you to move them correctly.The technique helps to break the bad habits accumulated over years. Try folding your arms the opposite way to normal. This is an example of a habit the body has formed which can be hard to break. Many of us carry our heads too far back. The head weighs four to six kilos, so any inappropriate posture can cause problems for the body. The technique teaches you to let go of the muscles holding the head back, allowing it to go back to its natural place on the top of our spines.So who was Alexander and how did he come up with the technique? Frederick Alexander, an Australian actor born in 1869, found in his youth that he had vocal (声音的) problems during performances. He analyzed himself and realized his posture was bad. He worked on improving it, with excellent results. He brought his technique to London and opened a teacher-training school, which is still successful today.So if you're walking along the road one day with shoulders bent forward, feeling weighed down by your troubles, give a thought to the Alexander technique. It will help you walk tall again.（1）What does the author suggest in Paragraph 1?A. She felt no better after the treatment.B. She got bored with the Alexander technique.C. She was sceptical about the doctor's method.D. She was unwilling to seek treatment for her backache.（2）What is the principle of the Alexander technique?A. Physical tension shouldn't be completely relieved.B. The technique shouldn't be combined with other exercises.C. The practice of the technique shouldn't be attempted alone.D. Familiar physical actions shouldn't be done with much effort.（3）What can we learn about Frederick Alexander?A. He managed to recover his vocal powers.B. He was eager to make a name for himself.C. He developed a form of exercise for actors.D. He had to leave home to develop his technique.（4）What is the main idea of the passage?A. The occurrence of back pain is widespread.B. Alexander improved the technique to treat body pain.C. The Alexander technique helps overcome posture problems.D. People with back pain are victims of inappropriate postures.【答案】（1）D（2）D（3）A（4）C【解析】【分析】本文是一篇说明文，介绍亚历山大技巧的对于矫正身体的作用以及其发明者。

From smart-home security to self-driving cars, all the internet-connected devices in your life will be able to talk to each other at lightning-fast speeds with reduced delay, Objectively speaking, the fastest 4G download speeds in the U. S. top out at an average of 19.42 Mbps. But by comparison 5G promises gigabit (千兆) speeds.“5G is one of those signs, along with artificial intelligence, of this coming data age,” said Steve Koenig, senior director of market research for the Consumer Technology Association. “The self-driving vehicle is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have massive amounts of data coming from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It's pulling in data from other vehicles about road conditions down the lane. It could be weather information, but also connected infrastructure (基础设施) construction. There's lots of data behind that task, which is why we need high speed.Augmented reality glasses and virtual headset haven't yet broken the mainstream, but tech companies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones.Ericsson stated at February's Mobile World Congress how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components, the glasses could rely on hardware for processing power.But don't get too excited. There's still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn't concentrated only in big cities.（1）What does the author want to stress in Paragraph 1?A.

A new study from brain researchers helps explain how the human brain evolved or changed over time, to permit people to speak and write.Michael Ullman, the lead researcher, a professor at Georgetown University Medical School in Washington, D.C, has been studying language learning for more than 20 years.Ullman says his research shows that the human brain does not have a special area or system for making language. Over time we have simply reused or co-opted (指派) parts of our brain for language. And those parts, he says, are ancient-older even than humans themselves."This study examines the theoretical framework (准则) that language is learned, stored and' processed in two ancient learning and memory systems in the brain."Ullman, Hamrick and the rest of the team looked at data from 16 other studies on language. They found that people learn language using two memory systems: declarative and procedural. Memorizing vocabulary, for example, is a declarative memory process. But learning grammar is, mostly, a procedural memory process."Declarative memory, in humans at least, is what we think of as learning memory', such as, 'Oh, remember what you said last night' or things like that. And procedural motor memory is what we often call motor memory' such as how you learn to ride a bicycle." Or, Ullman adds, "These procedural memory skills become so deeply leaned that we are no longer aware that we are doing them."However, Ullman explains that the two long-term memory systems can share tasks. And, he adds, the adult brain uses the systems to learn language a bit differently than a child's brain. "Adult language learners of a second language may use their declarative memory for using grammar patterns. They think about it purposefully. For a child, the grammar may come more naturally. They don't have to think about the grammar rules before speaking."In addition to language learners, Ullman's study could help people who have a brain injury that affects speaking and writing. This knowledge can also help those who have learning disabilities such as dyslexia (阅读障碍). People with dyslexia have difficulty recognizing words and symbols accurately.（1）How did Ullman study human's memory systems?A. By examining the brain with his team.B. By studying language learning over years.C. By comparing different languages year after year.D. By referring to data from other studies on language.（2）Which of the following is an example of "motor memory"?A. Learning to make a model plane.B. Remembering the grammar patternsC. Repeating what you heard.D. Memorizing what you read.（3）What does the underlined word "it" refer to?A. Declarative memory.B. An adult language learner.C. Using grammar patterns.D. A second language.（4）What's the main idea of the text?A. Ullman has advanced our language understanding.B. A new research helps people learn a new language.C. Learning memory is more active than motor memory.D. Human beings learn language in pre human area of brain.【答案】（1）D（2）A（3）C（4）D【解析】【分析】本文是一篇说明文，讲述Michael Ullman和他的团队的研究称人类大脑前区的为语言学习区，由此解开了人类大脑进化过程之谜。

When we see a person in trouble, the first idea that comes to our mind is to lend a hand. But what if we see an animal in trouble, does the same rule apply?This question was raised after a group of penguins were saved from an icy gully (峡谷) in Antarctica. It was filmed for the BBC wildlife series Dynasties. The film crew were anxious when they saw that a group of penguins had fallen into a gully and been trapped with their young. They built a slope (斜坡) so that a few of the penguins could save themselves.The case has taken the international media by storm. Viewers watching this film let out a sighof relief. "I'm so glad. I understand not taking action directly, but a helping hand isn't bothering, right?" viewer Kathryn Shaw said on her Facebook.However, others think human interference (干涉) is unnatural. "You can't have sunshine throughout your life. To have done anything else would only make matters worse," said the show's creator David Attenborough, according to The Times.In this case, however, Mike Gunton, the executive producer of the series, said that this was a one-off situation. "There were no animals going to suffer by interfering. You weren't touching the animals and it was just felt by doing this... they had the chance not to have to keep slipping downthe slope," he told the BBC.Such cases are familiar to Paul Nicklen, wildlife photographer for National Geographic. He told Metro, "If it's ever a predator (捕食者) situation, no matter how gut-wrenching, you stay out ofthe way. Even when you're watching a male polar bear eat a baby bear.""There's no rule book in those situations. You can only respond to the facts that are right therein front of you," Will Lawson, the show's director, told Daily Mail.（1）What has led to a heated media discussion?A.People's various remarks on penguins.B.The rescue of penguins from a gully.C.Some penguins' sufferings in a gully.D.Ways of filming the series Dynasties.（2）Who holds a positive attitude towards human interference?A.Kathryn Shaw.B.Will Lawson.C.Paul Nieklen.D.David Attenborough.（3）Which of the following best explains the word "gut-wrenching" underlined in paragraph 6?A.Putting one in place.B.Making one confused.C.Putting one in danger.D.Making one heartbroken.（4）What can be a suitable title for the text?A.Reasons for the Necessity of Lending a Hand to AnimalsB.Suggestions on How to Protect Animals From DangerC.Effects of Human Interference on Dangerous AnimalsD.Opinions on Whether to Help Animals in Trouble or Not【答案】（1）B（2）A（3）D（4）B【解析】【分析】本文是一篇说明文，介绍了当动物们面临危险时，我们是否要伸出援救之手，以及如何去保护它们脱险。

Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.This finding suggests that taking steps to prevent northern forest to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forestsin these areas over the past decade. Scientists predict that with climate warming, fires may occurmore frequently over next several centuries as a result of a longer fire season. Sunlight taken inby the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere andthus trap heat.Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone (臭氧) levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling."We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere." Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from theearth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.（1）According to the new findings, taking steps to prevent northern forest fires may ________.A. result in a warming climateB. cause the forest fires to occur more frequentlyC. lead to a longer fire seasonD. protect the forests and the environment there（2）The following are all the immediate effects after a forest fire EXCEPT ________.A. large amounts of greenhouse gases enter the atmosphereB. the levels of ozone which is a type of oxygen increaseC. snow on the ground mirrors more sunlight back into spaceD. ashes from the fire fall on the ice surface and take in more radiation from the sun（3）Earlier studies about northern forest fires ________.A. analyze all aspects of how northern fires influence climateB. indicate that forest fires will pollute the atmosphereC. suggest that people should take measures to protect the environmentD. suggest that the fires will speed up climate warming（4）The underlined phrase "soak up" in the last paragraph most probably means ________. A. released B. absorbed C. created D. distributed（5）From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberiamay ________.A. warm the climate as the supposition goesB. allow more snow to reflect more sunlight into space and thus cool the climateC. destroy large areas of forests and pollute the far-off sea iceD. help to gain more energy rather than release more energy【答案】（1）A（2）C（3）D（4）B（5）B【解析】【分析】本文是一篇说明文，介绍了阿拉斯加、加拿大和西伯利亚的森林大火使气候变暖，科学家们已经发现，在燃烧的树木允许更多的雪将更多的阳光反射到太空的地区可能会发生冷却。

（英语）高二英语阅读理解(科普环保)解题技巧和训练方法及练习题(含答案)含解析一、高中英语阅读理解科普环保类1．犇犇Choose the one that fits best according to the information given in the passage you have just read.While faking and fierce looks are among animals great defenses, many species know that everyone runs from a big stink (臭气) too.Vulture (秃鸳)Vultures, are street sweepers that feast on the rotting flesh of dead animals, which benefits us by ridding our highways and landscapes of animal bodies and the bacteria they might carry. When vultures feel threatened they vomit, and the smell of vomited-on dead bodies puts of most predators. Throwing up allows the vulture to fly away more quickly-and the vomit can hurt the aggressor's eyes and face.Opossum (负鼠)In some ways opossums have it easy. In order to become "dead", they don't have to fax anyone a death certificate. They just lie there with their tongues hanging out with the smell of dead flesh, sometimes for hours, effectively convincing potential predators they can find a much fresher meal elsewhere. Even if they keep getting attacked, they won't move any more than a human statue until the threat has passed.Hoatzin (磨雉)Hold your nose and meet the hoatzin, a bird of distinctions, not the least of which is that it smells like fresh cow shit. The animal mostly eats leaves and it's the only bird known to digest by fermentation, like a cow. This process is what causes its smell and has earned it the nickname the "stink birdMillipedes (千足虫)Millipedes are tricky. For starters they look wormy. Their name is deceptive, too: Their legs number about 750. Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.Sea Hare (海兔)The graceful sea hare is plain in taste in the first place, so it's not the most popular dish in the seafood chain. Nonetheless this type of sea creature has a pretty creative smell-related defense that is almost the opposite of its smelly companions on this list. The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.Researchers using lobsters (2-f) as model predators found that the sea blocks the lobsters receptive mechanism. In other words, the sea hare gives its attacker the equivalent of a stuffy nose so they don't know how appealing it is.（1）The sea hare defends itself from predators by ________.A. becoming plain in taste at the discovery of a predatorB. giving out purple ink to make itself invisible to predatorsC. releasing substance to make predators unable to smell itD. giving off smelly gas to try to drive predators away（2）Which of the following statements is TRUE according to the passage?A. The vulture carries bacteria so that predators dare not get close to it.B. The opossum fakes its death to avoid being targeted by predators.C. The hoatzin eats cow shit so that it is nick-named as "stink bird".D. The gas released by millipede was basically harmless.（3）The species that enjoys more than one defense mechanism is ________.A. vultureB. opossumC. millipedeD. sea hare【答案】（1）C（2）B（3）C【解析】【分析】本文是一篇说明文，介绍了一些野生动物是如何进行自身防御的。

A team of international scientists is due to set off for the world's biggest iceberg in a mission aiming to answer fundamental questions about the impact of climate change in the polar regions. The scientists, led by the British Antarctic Survey (BAS), are trying to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf.Last year, part of the Larsen C ice shelf calved (崩解) away, forming a huge iceberg-A68—which is four times bigger than London, and revealing life beneath for the first time. Now scientists say it is a race against time to explore these new ecosystems before they are transformed to the light. Marine biologist Dr Katrin Linse from the BAS is leading the mission."The calving of A68 provides us with a unique opportunity to study marine life as it responds to a huge environment change," she said. "It is important that we get there quickly before the undersea environment changes as sunlight enters the water."Professor David Vaughan, science director at the BAs, said, "We need to be bold (大胆的) on this one. Larsen C is a long way south and there's lots of sea ice in the area, but this is important science, so we will try our best to get the team where they need to be. He said climate change had already affected the sea around Antarctica and is warming some coastal waters. "Future warming may make some habitats warm. Where these habitats support unique species that are adapted to love the cold and not the warm, those species are going to either move or die."There is growing concern about the possible impact of climate change in the Antarctic. Earlier this month, a report revealed that melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of the sea level rise. The research, published by the National Academies of Science, Engineering and Medicine, said, "At the current rate, the world's ocean will be, on average, at least 60cm higher by the end of the century." However, it found that the process is accelerating, and more than three quarters of the acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.（1）Why are the scientists eager to go to the iceberg?A. To study how the iceberg was formed.B. To study a newly discovered ecosystem.C. To explore a new way to prevent climate change.D. To explore the geography of the Larsen C ice shelf.（2）What do the underlined words "this one" in the fourth paragraph refer to?A. The Larsen C ice shelf.B. Climate change in Antarctica.C. The A68 iceberg with the ecosystem beneath it.D. The condition of animal species in Antarctica.（3）What can we learn about the A68 iceberg from the text?A. It is as big as London.B. It is part of an ice shelf in the Arctic.C. It will disappear in a very short time.D. It has uncovered an unknown ecosystem in Antarctica.（4）What can we infer from the last paragraph?A. There is no need to worry about climate change in Antarctica.B. The ice sheets in Greenland and Antarctica are melting at a steady rate.C. Many creatures living in deep water will die out due to climate change.D. By 2100, the sea level will have risen to a much higher level than now.【答案】（1）B（2）C（3）D（4）D【解析】【分析】本文是一篇说明文，南极地区的拉森C冰架崩解形成了一座巨大的冰山A68 iceberg。

After a morning hike in the Saneum HealingForest, 46-year-old firefighter Kang Byoung-wook has tea made from the bark of an elm tree, practices yoga (瑜伽), and makes a picture with dried flowers. He is one of 40 firefighters taking part in a three-day program, the aim of which is to offer "forest healing" (森林治愈); the firefighters all have posttraumatic stress disorder (创伤后应激障碍).Saneum is one of three official healing forests in South Korea. Soon there will be 34 more. South Koreans-many of whom suffer from work stress, digital addiction, and great academic pressure have accepted the medicalization of nature with great enthusiasm.There is increasing evidence that being outside in a pleasant natural environment is good for us. But how many of us get to enjoy nature regularly? Fewer and fewer, it seems. According to Lisa Nisbet, a psychology professor at Canada s Trent University, evidence for the benefits of nature is pouring in at a time when we are most disconnected from it."We don't think of being outdoors as a way to increase happiness," says Nisbet. "We think other things will, like shopping or TV." But South Korea is starting to challenge this opinion.So what are some of the benefits of nature that Nisbet refers to? Being surrounded by nature has one obvious effect: It calms us and reduces our stress levels. This has been shown to lower blood pressure and heart rates.Another experiment conducted by psychologist Stephen Kaplan found that people who took a 50-minute walk in a park had better attention and short-term memory than those who took a walk along a city street.Perhaps what's more surprising is that nature may also make us more creative. David Strayer, a psychologist at the University of Utah, showed as much with a group of participants, who performed 50 percent better on creative problem-solving tasks after three days of wilderness backpacking.In fact, we may never know exactly what nature does to the brain. Something mysterious will always remain, and maybe that's as it should be.（1）What is Kang Byoung-wook doing?A.Getting lost in nature.B.Building up his strength.C.Trying to control a forest fire.D.Helping firefighters under stress.（2）What does Lisa Nisbet think of being outdoors?A.It is overlooked by people.B.It has nothing to do with happiness.C.South Koreans show great interest in it.D.We need more evidence for its benefits.（3）What benefit of nature did Stephen Kaplan find?A.It affects people's feelings.B.It lowers the risks of diseases.C.It helps improve mental performance.D.It does more good than physical exercise.（4）What would be the best title for the text?A.Your life in forestsB.Your brain on natureC.The future of forest healingD.The benefits of a stress-free life【答案】（1）A（2）A（3）C（4）B【解析】【分析】本文是一篇说明文，由韩国患创伤后应激障碍的消防员接受森林治愈谈起，介绍了大自然对我们身心健康的益处。

Tablets are really useful devices, but their big screens always make them as a burden to carry around without a bag. Wouldn't it be great if there were a phone with the powers of a tablet that could be folded up and fit neatly into the hand?Now something like a tablet-shaped but foldable phone is about to become available. In February, South Korean electronics company Samsung and China's Huawei both launched foldable phones, the Galaxy Fold and Huawei Mate X respectively. Mobile phone use has entered the "foldable future", The Verge noted.The technology could change our lives in significant ways. These devices, due to their bendable screens, give us the larger screens we want. Meanwhile, they still fit easily into the pocket. As USA Today noted, they're "the combination of a small tablet and smartphone, all in a single device".The technology could change other devices, too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers. In crowded modem cities, they will help us to maximize available space.In a keynote address, Samsung's senior vice president of mobile product marketing, Justin Denison, called the foldable screen "the foundation for the smartphone of tomorrow". "It's a blank canvas (画布) for us to do something beautiful together." he said.So is there nothing to stand in the way of the foldable future? According to tech news website Android Authority, the necessary displays were difficult to produce. In 2012, nine out of every 10 OLED (二极管) screens produced were imperfect. Today, that 10 percent rate has been improved to between 50 and 90 percent. However, at present these foldable devices are expensive. For example, the price of Huawei Mate X is 17,500 RMB. That's a price that few people will be able to afford.But if the foldable device isn't going to change the world overnight, there is no doubt that it is coming. Patrick Moorhead, an industry analyst told The Verge, "Few are debating if foldable or rollable mobile displays are the future of smartphones; the only question is when and by whom."（1）What can be the best title for the text?A. Screen devices on the market.B. Foldable age is arriving.C. Possible powers of a tablet.D. Foldable screens are imperfect.（2）What can we learn from Justin Denison's words?A. The foldable screen has great potential.B. The Galaxy Fold still has many problems.C. The production of foldable phones will soon increase.D. Companies need to work together to develop foldable phone.（3）What is the problem with foldable phones at the moment?A. They are easy to break.B. They are inconvenient to carry.C. They are not as useful as expected.D. They are unaffordable for most families.（4）What is the author's attitude toward the future of the foldable screen?A. Worried.B. Cautious.C. Positive.D. Unconcerned.【答案】（1）B（2）A（3）D（4）C【解析】【分析】本文是一篇说明文，介绍了“可折叠手机的时代即将到来。

Why does time seem to fly by faster as we get old? You've got your aging brain to blame. This is likely due largely to the physical changes of our nerves and neurons (神经元). New research suggests 'rapid fire' abilities of the young brain allow us to process more information during youth, causing the days to seem longer earlier in life. However, as we get old, researchers say the older brain takes more time to process information.The new finding put forward by a Duke University researcher was published in a paper in the journal European Review this week According to Adrian Bejan, the J. A Jones Professor of Mechanical Engineering at Duke, the physical changes of our nerves and neurons play, a major role in our perception (知觉) of time as we get old. Over the years these structures become more complex and eventually begin to degrade."Little babies, for example, move their eyes much more often than adults because they're processing images at a faster rate," Beian says, For older people, this means fewer images are being processed in the same amount of time, causing experiences to seem as though they're happening more quickly.（1）What causes time to fly faster as we get old?A. Changes of our nerves and neurons.B. Information in our brain.C. The electrical signals.D. Rapid fire abilities.（2）What is unavoidable in the process of getting old?A. Longer days.B. Aging brains.C. More images.D. Less experience.（3）Why do the days seem longer earlier in life?A. Young people are more energetic in their life.B. The younger brain takes less time to process information.C. Old people have fewer things to do than young people.D. Little babies move their eyes much more often.（4）What is the best title of the text?A. Nerves and NeuronsB. Time Flies FastC. The Older, the FasterD. The Function of the Brain【答案】（1）A（2）B（3）B（4）C【解析】【分析】本文是一篇说明文，介绍了为什么老年人会觉得时间过得较快，主要原因是随着年龄的增长，大脑中神经元的变化让老年人的大脑需要更多的时间来处理接收到的信息，这样就会让他们觉得时间过得较快。

（1）考查细节理解。

根据第一段中的 "This is likely due largely to the physical changes of our nerves and neurons (神经元)."可知，老年人觉得时间过得过快的原因是神经和神经元的变化。

故选A。

（2）考查推理判断。

根据第一段中的"You've got your aging brain to blame."和第二段中的"Over the years, these structures become more complex and eventually begin to degrade."可知，随着年龄的增长，不可避免的就是大脑结构的老化。

故选B。

（3）考查推理判断。

根据第一段中的最后两句可知，年轻时之所以觉得日子似乎更长是因为大脑能够以“快速射击”的方式处理更多信息。

当我们变老的时候，大脑需要更多的时间来处理信息。

所以说，相较于老年人，年轻人的大脑花费更少的时间来处理信息。

故选B。

（4）考查主旨大意。

文章首句点明了文章谈论中心：为什么随着我们变老，我们会觉得时间过得更快？后面文章主要解释了原因：老年人因为大脑退化，神经元的变化导致他们觉得时间过得较快。

C项正好与主旨句呼应，故选C。

【点评】本题考点涉及细节理解，推理判断和主旨大意三个题型的考查，是一篇科研类阅读，考生需要准确捕捉细节信息，同时根据上下文进行逻辑推理，概括归纳，从而选出正确答案。

2．犇犇阅读理解A study found wireless signals are able to pass through bags and suitcases to judge the sizes of dangerous metal objects and identify them." These items could include weapons, chemicals, laptops and batteries for bombs, "the research team said on Tuesday.Research suggested that Wi-Fi can now be used to estimate the volume of liquids such as water, acid, alcohol and other chemicals for explosive material. The study led by researchers at the Wireless Information Network Laboratory (WINLAB) in the School. of Engineering showed a wireless device with two to three antennas(天线)that could be fitted in existing Wi-Fi networks. The detection system analyzes what happens when wireless signals go through and bounce off objects or materials. The approach, which the paper states, works by separating the wireless interference(干扰)caused by two factors of objects-the material and shape." Most dangerous objects such as weapons are usually metal or liquid, which have significant interference," researchers said.When it was tested on a backpack, the accuracy rate topped 95 percent. "But the accuracy dropped to about 90 percent when objects inside bags are wrapped. And the tech could save lives if used in museums, stadiums, theme parks or schools," the team said, noting its design can inspect bags or luggage without being an exposure to privacy.It uses channel state information (CSI) that is readily available in low-cost Wi-Fi devices." This could have a great impact on protecting the public from dangerous objects," said Yingying Chen, a co-author of the study," There's a growing need for that now. In large public areas, it's hard to set up expensive screening equipment like what's in airports. Manpower is always needed to check bags and we want to develop a method to try to reduce manpower.”The peer-reviewed study, which recently won a best paper award at the 2018 IEEE Conference on Communications and Network Security, is now published online." Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes," researchers said.（1）What does paragraph 3 talk about?A.
