50套高中英语阅读理解(科普环保)含解析一、高中英语阅读理解科普环保类1．犇犇阅读理解While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand. They became the world's first kids to be "taught" by a digital teacher. Before you start imagining a human-like robot walking around the classroom, Will is just an avatar that appears on the student's desktop, or smartphone screen, when ordered to come.The autonomous animation platform has been modeled after the human brain and nervous system, allowing it to show human-like behavior. The digital teacher is assigned to teach Vector's "Be sustainable with energy" — a free program for Auckland elementary schools.Just like the humans it replaced, Will is able to instantly react to the students' responses to the topic. Thanks to a webcam and microphone, the avatar not only responds to questions the kids may have, but also picks up non-verbal cues. For instance, if a student smiles at Will, he responds by smiling back. This two-way interaction not only helps attract the students' attention, but also allows the program's developers to monitor their engagement, and make changes if needed.Nikhil Ravishankar believes that Will-like avatars could be a novel way to catch the attention of the next generation. He says, “I have a lot of hope in this technology as a means to deliver cost-effective, rich, educational experience in the future.”The program, in place since August 2018, has been a great success thus far. Ravishankar says, " What was fascinating to me was the reaction of the children to Will. The way they look at the world is so creative and different, and Will really captured their attention." However, regardless of how popular it becomes, Will is unlikely to replace human educators any time soon.（1）What was special for some elementary school students in Auckland?A. A digital teacher taught them.B. They first saw something digital.C. This was the start of a new school year.D. They could get close to smartphone screen.（2）What is the benefit of this two-way interaction?A. It can smile back.B. It can use microphone.C. It can talk any topic for free.D.

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。

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。

高一英语阅读理解(科普环保)试题(有答案和解析)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.The Rapid Rise and Fall of Robot BabysittersDuring the winter of 2017, an 18-year old college student named Canon Reeves spent much of his time trailing a knee-high robot around Fayetteville, Arkansas, as it delivered Amazon packages to students. The robot, created by a start-up called Starship Technologies in 2014, is basically a cooler on wheels; it uses radars, sensors, and nine cameras to make deliveries. Reeves's job was to monitor how it handled various grounds, field comments from the public, and press the off switch if necessary. He said, "People would also ask if it could deliver beer." It couldn't.Broadly speaking, jobs of caring for robots fall under the umbrella of careers in automation, which include maintenance, engineering and programming. The demand for people with this skill set is considerable, with 20 million to 50 million new jobs to be expected in this category by 2030, according to the Mckinsey Global Institute. In the year that ended in June 2018, had almost three times the number of positions on the recruitment committee that ended in June 2016.Over the last year, a 34-year-old businessman named David Rodriguez spent hundreds of hours following a machine called the KiwiBot around UC Berkeley's campus while it delivered Red bull and other drinks to students. To retrieve (检索) orders, the app encourages students to give the robot a wave; the robot's digital eyes will roll depending on its mood. Rodriguez, who heads business development for the start-up, was tasked, early on, with monitoring the KiwiBot for problems – even carrying it, should the motors fail. Since April 2018, though, the KiwiBot has largely been left unattended, and the majority of human interactions involve technical checks and loading food into the robot. To eliminate the boring work, the team is developing a restaurant robot to collect and load orders – which could happen in 2020. However, Rodriguez assured me that his staff won't be out of work. Everyone holds double roles in the company. Greater robot self-governing just means employees will shift their focus to accounting, engineering, and design. Mckinsey estimates that millions of jobs globally could be lost to automation by 2030. "A huge number of jobs will be produced as autonomous vehicles are released into the environment," Ramsey said. In 2016, Bosch started training students from Schoolcraft College, a community college in Michigan, in autonomous-vehicle repair; Toyota has trained students in maintenance as well. "We might even see a return to low-level jobs where people come and fuel the car for you," Ramsey said. "Until we can wirelessly charge, someone needs to refuel them." The hardest-to-automate industries, as it happens, are the ones that require looking after humans, such as childcare, education and health care. Robot babysitters might feel like they have scored the job of the future, but in fact, they might be better positioned.（1）What kind of robot is the one created by a start-up called Starship Technologies? A. A factory robot. B. A delivery robot. C. A restaurant robot. D. A construction robot.（2）What does "fall under the umbrella of" in Para. 2 mean?A. are in the category ofB. are under the protection ofC. are in relation ofD. are in the process of（3）According to Ramsey, what will happen when autonomous vehicles are put on the market?A. Autonomous vehicles will become much cheaper.B. A large number of people will be out of work.C. A lot of job opportunities will be created.D. Many people will turn to buying autonomous cars.（4）What does the last sentence in Para. 4 mean?A. Robot carers will have a competitive advantage in the future.B. Many new occupations like caring for robots come and go fast.C. We still need someone to look after robots in the future.D. Robots will create more and better jobs for people in the future.【答案】（1）B（2）A（3）C（4）A【解析】【分析】本文是一篇说明文，随着机器人被越来越多的应用，照看机器人的工作也随之发生了变化。

This process prevents the virus from mixing with human cells. The scientists say it can remove the effect of the virus and block its spreading.The Joint United Nations Program on HIV/AIDS reports that worldwide, nearly 37 million people were living with HIV in 2017. The organization says the largest number of those are in developing countries. Nearly two-thirds of HIV cases are in Africa. Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease.The new study predicts the rice-based method will lead to long-term use of the anti-HIV treatment across the developing world. Researchers said the "groundbreaking" discovery is "realistically the only way" that anti-HIV combination treatments can be produced at a cost low enough for the developing world.They say the easiest and most cost-effective way to use the rice will be to make it into a cream to be put on the skin. The HIV-fighting proteins can then enter the body through the skin. People all over the world could grow the rice and make the cream themselves. This would prevent the cost and travel required for many patients to receive treatments and medicine.The process of changing the genetic structure of food crops has been debated for some time. Critics of genetically engineered crops believe they can harm people.

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.

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.

高中英语阅读理解(科普环保)技巧和方法完整版及练习题含解析一、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。

【英语】高二英语阅读理解(科普环保)试题经典含解析一、高中英语阅读理解科普环保类1．犇犇阅读理解In our twenties, we find it funny when we can't remember our neighbor's cat's name or a handsome actor who starred in a famous movie. In our thirties, we jokingly call it "brain freeze". In our forties, we laugh it off as a" senior moment" and follow up with one of these old age jokes. But the reality is that there comes a point when being forgetful stops being funny and starts to seem a bit dreadful. You think, "Am I losing it？"Or worse, "Is this a sign of Alzheimer's disease （老年痴呆症）？"Well, don't worry. The fact that you recognize your own forgetfulness may be a very good sign, at least in terms of the possibility of your developing Alzheimer's disease（AD）. The researchers in a new study show that it's not forgetfulness but not being aware that we're forgetful that we should fear.The researchers began with the assumption that one common feature of Alzheimer's dis-ease is a damaged awareness of illness. And they wanted to prove their theory that the lack of awareness can be used to predict whether someone with" mild cognitive（认知的）damage" will progress to full-on AD. For the study, "mild cognitive damage" was defined as someone whose mental state was considered healthy but who had either complained of memory loss or had suffered objective memory loss.The researchers used existing data for 1, 062 people between the ages of 55 and 90 that had been recorded over a 12-year period. The data included brain scans, which the researchers used to look for visual signs of reduced glucose uptake（葡萄糖吸收）.It is an objective marker of the sort of reduced brain function that goes along with AD.As expected, glucose uptake was reduced in those with AD. What the researchers also discovered was that glucose uptake was reduced in those with mild cognitive damage who also showed evidence of reduced illness awareness. Finally, the researchers found that those who had reduced illness awareness were more likely to develop AD than those without.（1）What can be implied from paragraph 1？A. People can be forgetful at different ages.B. The memory of the young is better than the old.C. Old people are most afraid of getting Alzheimer's disease.D. It's a rare phenomenon when young people forget something.（2）What statement does the researchers in the new study agree with?A. Being aware all the time is a fearful thing.B. Illness awareness has nothing to do with Alzheimer's disease.C. Recognizing forgetfulness doesn't mean developing Alzheimer's disease.D. Realizing forgetfulness must be a sign of developing Alzheimer's disease.（3）What can be a sign of developing Alzheimer's disease?A. Realizing others' forgetfulness.B. Reduced uptake of glucose.C. Having higher intake of glucose.D. Expected increase in brain function.（4）From which is the text probably taken?A. Science fiction.B. A chemistry book.C. A science research.D. A health brochure.【答案】（1）A（2）C（3）B（4）C【解析】【分析】本文是一篇说明文，介绍了如何预测你的记忆丧失是否是老年痴呆症, 一项新的研究表明，不是遗忘，而是没有意识到我们的健忘让人们感到害怕。

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。

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.

They became the world's first kids to be "taught" by a digital teacher. Before you start imagining a human-like robot walking around the classroom, Will is just an avatar that appears on the student's desktop, or smartphone screen, when ordered to come.The autonomous animation platform has been modeled after the human brain and nervous system, allowing it to show human-like behavior. The digital teacher is assigned to teach Vector's "Be sustainable with energy" — a free program for Auckland elementary schools.Just like the humans it replaced, Will is able to instantly react to the students' responses to the topic. Thanks to a webcam and microphone, the avatar not only responds to questions the kids may have, but also picks up non-verbal cues. For instance, if a student smiles at Will, he responds by smiling back. This two-way interaction not only helps attract the students' attention, but also allows the program's developers to monitor their engagement, and make changes if needed.Nikhil Ravishankar believes that Will-like avatars could be a novel way to catch the attention of the next generation. He says, “I have a lot of hope in this technology as a means to deliver cost-effective, rich, educational experience in the future.”The program, in place since August 2018, has been a great success thus far. Ravishankar says, " What was fascinating to me was the reaction of the children to Will. The way they look at the world is so creative and different, and Will really captured their attention." However, regardless of how popular it becomes, Will is unlikely to replace human educators any time soon.（1）What was special for some elementary school students in Auckland?A.

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.

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 occur more 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 and thus 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 the earth 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. releasedB. absorbedC. createdD. distributed（5）From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may ________.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。

高中英语阅读理解（科普环保类）Passage 1Canadian smart phone maker Research In Motion (RIM), which makes the BlackBerry, says it’s back. The company is 1 to reclaim a market it once dominated by 2 two new devices. The last few years have been a painful time for the company as customers deserted its platform in 3 of newer and more 4 devices.
