高考英语高中英语阅读理解习题及答案

一、高中英语阅读理解1．阅读理解The founder of electric supercar maker Rimac has said it won't make sense for people to own or drive their own cars in the coming decades.According to Rimac, most people will no longer own or operate their own cars in the future. Instead, vehicles will be shared, self—driving and electric. These changes are already starting. "There will be people who still want to own their cars and drive their cars and I am happy for that because that is our business," Rimac said. "Long term, I think 20 years down the road, it will be totally changed and people will not own or drive their cars anymore." Rimac's most recent car, the C—Two, comes off the production line next year.Rimac is well aware the industry is changing quickly due to the rise of self-driving vehicles and electric batteries, and says in the next 20 years driving as we know it may exist mainly as a hobby. "I really believe that humanity goes for things that make sense." he told Newsweek. "If you look at 1.3 million people dying every year on the roads, if you look at the impact it has on economies based on traffic jams and time lost, it's so much of a negative impact to society that I think such a huge benefit can be gained if people stop driving.""Let's look into the future. You are standing in front of the choice of either investing a huge amount of your money in buying a hunk of metal and plastic for 30, 40, 50 thousand dollars, or you have the convenient option of paying as you go, the car picks you up in a few minutes, it's a nice environment and you spend a few dollars per day on your transport.""When you take the driver out of the car, transport can be much cheaper and you can use the time to do other things, instead of sitting behind a steering(转向)wheel and not doing anything else. So I think the choice for the vast majority of people will be the obvious one."（1）What can we learn from paragraph 2?A.The majority of people will purchase cars.B.Huge changes will take place in car industry.C.Driving cars will enjoy more popularity.D.The car business is gradually disappearing.（2）What is a major cause of the fast change in the car industry?A.The rapid growth of self-driving cars.B.The rise of shared vehicles.C.The increasing demand of customers.D.The advanced production line.（3）How does Rima feel about the future of self-driving cars?A.Uncertain.B.Confused.C.Optimistic.D.Frightened.（4）What can be a suitable title for the text?A.Self-driving cars meet new challenges.B.Self-driving cars avoid human errors.C.Possessing or driving cars won't be a must.D.Conventional cars will be completely replaced.【答案】（1）B（2）A（3）C（4）C【解析】【分析】本文是一篇议论文，讲述了由于自动驾驶车辆和电池的兴起，在不远的将来人们不用再买车和驾车，此外自动驾驶车辆将给社会和环境带来巨大好。

一、高中英语阅读理解1．阅读理解It started during a yoga class. She felt a strange pull on her neck, a feeling completely foreign to her. Her friend suggested she rush to the emergency room. It turned out that she was having a heart attack.She didn't share similar symptoms with someone who was likely to have a heart attack. She exercised, watched her plate and did not smoke. But on reviewing her medical history, I found that her cholesterol (胆固醇) level was sky-high. She had been prescribed a cholesterol-lowering statin (他汀) medication, but she never picked up the prescription because of the scary things she had read about statins on the Internet. She was the victim of fake medical news.While misinformation has been the object of great attention in politics, medical misinformation might lead to an increase in deaths. As is true with fake news in general, medical lies tend to spread further than truths on the Internet—and they have very real bad consequences.False medical information can also lead to patients experiencing greater side effects through the "nocebo effect (反安慰剂效应) ". Sometimes patients benefit from an intervention (干预) simply because they believe they will—that's the placebo effect (安慰剂效应). The nocebo effect is the opposite. Patients can experience harmful effects because they anticipate them. This is very true of statins. In blinded trials, patients who get statins are no more likely to report feeling muscle aches than patients who get a placebo. Yet, in clinical practice, according to one study, almost a fifth of patients taking statins report side effects, leading many to discontinue the drugs. What else is on the fake news hit list? As always, vaccines (疫苗) . False concerns that the vaccine may cause side effects have greatly reduced coverage rates.Cancer is another big target for pushers of medical misinformation—many of whom refuse alternative therapies. "Though most people think cancer tumors are bad, they're actually the way your body attempts to contain the harmful cells," one fake news story reads. It warns that prescription medications lead to the uncontrolled cell mutations (变异) .Silicon Valley needs to face this problem. I am not a free-speech lawyer, but when human health is at risk, perhaps search engines, social media platforms and websites should be held responsible for promoting or hosting fake information. Meanwhile, journalists should do a better job of spreading accurate information.（1）We can learn from Paragraph 2 that ________.A. the woman paid little attention to her daily dietsB. the unhealthy lifestyle might lead to the woman's heart attackC. the symptom of the heart attack was familiar to the womanD. the woman didn't take the prescription due to fake medical news（2）According to the passage, the placebo effect functions because patients ________. A. neglect necessary treatment B. discontinue the harmful drugsC. believe the benefits of an interventionD. suffer more side effects（3）What does the author mean by claiming that "he is not a free-speech lawyer" in the lastparagraph?A. He is a lawyer very easy to speak to.B. He is good at speaking because of his job.C. He is available to give a speech on the law.D. He is very cautious when speaking something（4）The main purpose of the passage is to ________.A. remind us to take medication as prescribedB. warn us against fake medical news on the InternetC. encourage journalists to report more positive news eventsD. teach us how to distinguish fake medical news on the Internet【答案】（1）D（2）C（3）D（4）B【解析】【分析】本文是一篇议论文，通过举例来论证了网络谣言，尤其是关于药物的网络谣言有巨大的杀伤力。

一、高中英语阅读理解1．阅读理解Gene technology to benefit peopleAmong all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(寿命) can be prolonged.Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial(皇室) family being a good example, have hereditary(遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it and a healthy child will be born.Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.（1）What does "these two killers" in the second paragraph refer to?A. Gene technology and another treatment of the two diseases.B. The two murderers who killed the cloned baby.C. The two diseases of cancer and heart disease.D. Hereditary diseases and cancer.（2）What's the main idea of the third paragraph?A. How gene technology can be applied in the field of treating hereditary diseases.B. Gene technology can be used to clone human babies.C. Gene technology can help people to give birth of a baby.D. Gene technology can help the English imperial family out.（3）In what way gene technology can help to treat hereditary diseases?A. Using gene technology, people with hereditary diseases can have more living days.B. Using gene technology, scientist finds the wrong gene and corrects it.C. Using gene technology, human babies can be cloned.D. Doctors can cure cancer and heart disease with the help of gene technology.（4）What is the main purpose of writing this passage?A. Expressing the writer's idea that gene technology will benefit peopleB. Telling people the advantages of gene technologyC. Telling the readers that gene technology will not benefit peopleD. Explaining that gene technology will also do harm to the humanity【答案】（1）C（2）A（3）B（4）A【解析】【分析】本文是一篇说明文，介绍了基因技术，详细讲述了基因技术的好处。

怎样上好高中英语阅读理解题的讲评课——以一节科普类说明文的讲评课为例

课堂指津“普通高中英语课程标准（2017年版）”指出，主题为语言学习提供主题范围或主题语境。

学生对主题意义的探究应该是学习语言的最重要内容，直接影响学生对语篇理解的程度、思维发展的水平和语言学习的成效。

主题语境不仅规约着语言知识和文化知识的学习范围，还为语言学习提供意义语境，并渗透情感、态度和价值观。

英语阅读理解题的讲评如果只专注于大量高考真题或模拟题的训练和讲解，把重点放在语法、词汇、单句的分析理解上，用“翻译法”理解文章，而缺乏对语篇的主题意义以及思维逻辑关系的重视，没有系统性和整体性，那么就无法培养学生的英语语言综合运用能力、语篇意识和思维品质。

“探究主题内容是学生学习的兴趣来源，能够使学生更深层次地理解语篇，也可以通过主题式教学提高语言学习的效率，使学生从中获得知识、经验、智慧。

对周围世界有更深刻的理解”。

因此，在高中英语阅读理解题的讲评教学中，教师应围绕相应主题以及复习目标，通过分析语篇的主题意义、语篇结构、语言特征等，有效利用语篇培养学生的阅读能力、语言能力和思维品质。

科普类说明文词汇量大、长难句多，信息丰富，这些都为学生的阅读带来了很大的挑战。

此外，科普类说明文阅读选材与学生的实际生活缺乏关联性，很难激发学生的阅读兴趣。

本文将通过一次高三英语科技说明文阅读理解题讲评课，探讨如何在高三英语教学中有效落实基于主题意义探究的教学理念。

1.教学内容与目标本节课重点选取近年江苏高考阅读理解题中的两篇科技类说明文，包括2017年的B篇（以下简称passage A）和2013年的C篇（以下简称passage B）。

两篇科普类型的文章都是以“人与环境、人与动植物”为主题，通过自然界动物的一些现象，展现科学研究的过程，引起学生对人与自然的思考。

科普类阅读的特点是专业词汇和背景知识较多，但文章逻辑和结构清晰，对学生语言知识、文化知识和思维逻辑方面的要求比较高。

教师应以“人、环境、动物”为主题，结合学生的生活实际探究主题意义———自然法则、生物进化和适者生存。

【英语】高三英语阅读理解解题技巧及练习题(含答案)及解析

【英语】高三英语阅读理解解题技巧及练习题(含答案)及解析一、高中英语阅读理解1．阅读理解Since English biologist Charles Darwin published On the Origin of Species in 1859, scientists have vastly improved their knowledge of natural history. However, a lot of information is still of the speculation, and scientists can still only make educated guesses at certain things.One subject that they guess about is why some 400 million years ago, animals in the sea developed limbs (肢) that allowed them to move onto and live on land.Recently, an idea that occurred to the US paleontologist (古生物学家) Alfred Romer a century ago became a hot topic once again.Homer thought that tidal (潮汐的) pools might have led to fish gaining limbs. Sea animals would have been forced into these pools by strong tides. Then, they would have been made either to adapt to their new environment close to land or die. The fittest among them grew to accomplish the transition (过渡) from sea to land.Romer called these earliest four-footed animals “tetrapods”. Science has alw ays thought that this was a credible theory, but only recently has there been strong enough evidence to support it.Hannah Byrne is an oceanographer (海洋学家) at Uppsala University in Sweden. She announced at the 2018 Ocean Sciences Meeting in Oregon, US, that by using computer software, her team had managed to link Homer's theory to places where fossil deposits (沉积物) of the earliest tetrapods were found.According to the magazine Science, in 2014, Steven Balbus, a scientist at the University of Oxford in the UK, calculated that 400 million years ago, when the move from land to sea was achieved, tides were stronger than they are today. This is because the planet was 10 percent closer to the moon than it is now.The creatures stranded in the pools wo uld have been under the pressure of “survival of the fittest”, explained Mattias Green, an ocean scientist at the UK's University of Bangor. As he told Science, “After a few days in these pools, you become food or you run out of food... the fish that had large limbs had an advantage because they could flip (翻转) themselves back in the water.”As is often the case, however, there are others who find the theory less convincing. Cambridge University's paleontologist Jennifer Clark, speaking to Nature magazine, seemed unconvinced. “It's only one of many ideas for the origin of land-based tetrapods, any or all of which may have been a part of the answer,” she said.（1）Who first proposed the theory that fish might have gained limbs because of tidal pools?A. Alfred Romer.B. Charles Darwin.C. Hannah Byrne.D. Steven Balbus.（2）Why were tides stronger 400 million years ago than they are today according to Steven Balbus?A. There were larger oceans.B. Earth was closer to the moon.C. The moon gave off more energy.D. Earth was under greater pressure.（3）The underlined word “stranded” in Paragraph 8 probably means “________”.A. foundB. settledC. abandonedD. trapped（4）What is the focus of the article?A. The arguments over a scientific theory.B. The proposal of a new scientific theory.C. Some new evidence to support a previous theory.D. A new discovery that questions a previous theory.【答案】（1）A（2）B（3）D（4）C【解析】【分析】本文为一篇说明文，一些新的证据验证了先前人们的猜测理论：即海洋中的动物是因为潮汐的作用导致鱼类发展出四肢，迁徙到陆地的。

高中英语-阅读理解(科技类)01

阅读理解〔科技类〕Passage OneThe computer is a useful machine. It is the most important invention in many years. The oldest kind of computer is the abacus(算盘), used in China centuries ago, but the first large, modern computer was built in 1946. A computer then could do maths problems quite fast.Today computers are used in many ways and can do many kinds of work. In a few years the computer may touch the life of everyone, even people in faraway villages.In the last few years, there have been great changes in computers. They are getting smaller and smaller, and computing faster and faster, Many scientists agree that computers can now do many things, but they cannot do everything. Who knows what the computers of tomorrow will be like? Will computers bring good things or bad things to people? The scientists of today will have to decide how to use the computers of tomorrow.1. The computer is a _______ machine.A. helpfulB. strangeC. largeD. dangerous2. The first large, modern computer was built about _______ years ago.A. a fewB. fortyC. sixtyD. eighty3. The computers of today are _______ than before.A. biggerB. fewerC. smallerD. taller4. Computers can do _______.A. everythingB. anythingC. nothingD. lots of things5. The scientists of today _______ how to use the computers of tomorrow.A. may decideB. must decideC. can makeD. needn’t makePassage TwoWarm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him until 1970. In that year a Canadian scientist George Kill proved the English professor was right. Dr Kill filled an open oil pail(桶) with cold water. He filled another with warm water. He put both in the same low temperature. The warm water froze first. The lack of covers on the pails is the secret. Some of the warm water changed into vapor. This meant that less of the warm water was left to be frozen. And so the warm water froze faster than the cold water even though it had a greater temperature drop to make.1. Hundreds of years ago, Sir Francis Bacon found _______.A. the temperature of warm water drops faster than that of cold waterB. warm water is heavier than cold waterC. warm water has the same temperature as cold waterD. warm water is not as useful as cold water2. What Sir Francis Bacon said was right, but people didn't believe him until _______.A. late in the 20th centuryB. early in the 20th centuryC. three years agoD. late in the 19th century3. Leave a pail with warm water and another pail with cold water in the same low temperature, you’ll find that _______.A. cold water freezes firstB. warm water turns into ice before cold waterC. warm water and cold water freeze at the same timeD. much of cold water is changed into air.4. Why does warm water freeze first in the same freezing weather?A. Because some of the warm water turns to vapor, the amount(数量) becomes less than that of cold water.B. Because warm water is lighter than cold water.C. Because the temperature of warm water is lower than that of cold water.D. Because cold water freezes with more difficulty than warm water.Passage ThreeIf you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault(过错). But if he tells us that he has a poor memory, many of us think that his parents are to blame(受责备), and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.1. The main reason for one is poor memory is that _______.A. his father or mother may have a poor memoryB. He does not use his name or legs for some timeC. his memory is not often usedD. he can’t read or write2. If you do not use your arms or legs for some time _______.A. you can’t use them any moreB. they will become strongerC. they become weak and won’t become strong until you use them again.D. they will become neither stronger nor weaker3. Which of the following is NOT true?A. Your memory works in the same way as your arms or legs.B. Your memory, like your arms or legs, becomes weak if you don’t give it enough chance for practice.C. Don’t learn how to read and write if you want to h ave a better memory.D. A good memory comes from more practice.4. Some people can’t read or write, but they usually have better memories, because _______.A. they have save much troubleB. they have saved much time to remember thingsC. they have to use their memories all the timeD. they can’t write everything in a little notebook5. Which is the best title for this passage?A. Don’t Stop Using Your Arms Or LegsB. How To Have a Good MemoryC. Strong Arms And Good MemoriesD. Learn From the PeoplePassage FourWhen Johnson called again, the manager received him very politely. “That is a most remarkable oil you brought us, Mr Johnson,” he said. Johnson nodded his smooth, dark head. That was something he knew very well. “I’ve never seen anything like it,” the manager admitted. Johnson nodded again. “No?” he said politely. Then he added, “But I think you will, sir. A very great deal of it.” He appeared to think for a moment. “I think you will find it will be on sale seven, perhaps, eight years from now.” He smiled.The manager thought that was uncertain. He said, “It is better than our fish oils. I admit that.”“So I am told, sir,” agreed Johnson.“Have you any plans to produce it yourself, Mr Johnson?”“Would I be showing it to you if I had?” Johnson smiled again.“We might add some chemicals to one of our own fish oils,” said the manager. “It would be expensive to do that, even if you could,” Johnson said gently. “Besides,” he added, “I am told that this oil will be much cheaper th an your best fish oils. Cheaper than any vegetable oil, in fact.”“Perhaps,” said the manage. “Well, I suppose you want to make an arrangement, Mr Johnson. Shall we discuss it?”“Of course,” said Johnson. “There are two ways of dealing with a situation o f this sort. The usual one is to prevent it altogether or at least to delay it as long as possible. That is, of course, the best way.” The manager nodded. He knew plenty about all that.“But I am so sorry for you, because, you see, that is not possible this time.” The manager had his doubts, but all he said was an inquiring(asking), “Oh?”“The other way,” continued Johnson, “is to produce yourself before the trouble starts.”1. The manager thought of adding chemicals to the fish oil to make it _______.A. cheaper than the new oilB. more quicklyC. more expensiveD. as good as the new oil2. Johnson’s new oil would be _______.A. more expensive than fish oil, but betterB. less expensive, and betterC. less expensive, but not goodD. more expensive, and not so good3. Johnson expressed his regret that the manager _______.A. could not stop the new oil being madeB. would never know how to make itC. had spent a lot of money on itD. d idn’t know enough about it4. Johnson showed his new oil to the manager because he wanted _______.A. to produce it himselfB. to prevent it being producedC. to be paid not to produce itD. the manager to produce itPassage FiveCan you remember the first time you learned to ride a bike or drive a car? Learning these skills changed your life forever and opened up new horizons. Learning about computers can be like learning how to ride a bike or drive a car. Once you have invested the time to master the skills, you will never go back to the old days. The new technology is simply too convenient and too powerful.Technological developments through the years have enabled us to do more with less effort. We have continuously looked for better ways of doing things. Each invention and new development has allowed us to extend our capabilities. Today we see one of the most dramatic technologies ever developed—the computer. It extends the capabilities of our minds.Computers have saved organizations millions of dollars. Furthermore, these same computer systems have opened up new opportunities that would have gone undiscovered or neglected. The computer may multiply what we can do, and the return on investment is high. The growth of computer usage is surprising. On the other hand, the computer can do serious damage. Invasion of privacy(侵犯隐私), fraud(欺诈), and computer-related mistakes are just a few shocking examples.The computer is like a double-edged sword. It has the ability to cut us free from some activities, but it can also cut deep into profits, personal privacy, and our society in general. How it is used is not a function of technology. It is strictly a function of how people decide to use or misuse this new technology. The choice is yours, and only through a knowledge of computer systems will you be able to avoid the dangers while enjoying the many, many benefits of the computer age.1. The writer thinks learning about computers is like learning how to ride a bike or drive a car because _______.A. it is simple and practicalB. it needs a lot of practiceC. it leads people to new life experiencesD. it takes much time to master the skills2. According to the passage, computers bring people the following benefits except _______.A. avoiding mistakesB. saving moneyC. making moneyD. opening up opportunities3. According to the writer, the bad effects of computers can be avoided if we _______.A. have sound knowledge of computer systemsB. tell people not to misuse computersC. have strict rules over the use of computersD. make more investments in the technology4. This passage is probably written for _______.A. computersB. computer producersC. computer learnersD. computer programmersPassage SixPerhaps you have heard a lot about the Internet, but what is it, do you know? The Internet is a network. It uses the telephone to join millions of computers together around the world.Maybe that doesn’t sound very interesting. But when you’ve joined to the Internet, there are lots and lots of things you can do. You can send E-mails to your friends, and they can get them in a few seconds. You can also do with all kinds of information on the World Wide Web (WWW).There are many different kinds of computers now. They all can be joined to the Internet. Most of them are small machines sitting on people’s desks at home, but there are still many others in schools, offices or large companies. These computers are owned by people and companies, but no one really owns the Internet itself.There are lots of places for you to go into the Internet. For example, your school may have the Internet. You can use it during lessons or free time. Libraries often have computers joined to the Internet. You are welcome to use it at only time.Thanks to the Internet, the world is becoming smaller and smaller. It is possible for you to work at home with a computer in front, getting and sending the information you need. You can buy or sell whatever you want by the Internet. But do you know 98% of the information on the Internet is in English? So what will English be like tomorrow?1. What is the passage mainly about?A. Internet.B. Information.C. Computers.D. E-mails.2. Which is the quickest and cheapest way to send messages to your friends?A. By post.B. By E-mail.C. By telephone.D. By satellite.3. Which may be the most possible place for people to work in tomorrow?A. In the office.B. At school.C. At home.D. In the company.4. Whose the owner of the Internet?A. The headmaster.B. The officer.C. The user.D. No one.5. What does the writer try to tell us with the last two sentences?A. English is important in using the Internet.B. the Internet is more and more popular.C. Most of the information is in English.D. Every computer must have the Internet.Passage SevenIn most towns today, you can see teenagers standing over electronic machines with flashing lights, shooting at spaceships from other planets and dropping bombs on strange monsters(恶魔). The machines have names like Space Warrior, Dark Invader and so on. It used to be believed that damage was done only to those strange visitors from outer space, but now it seems that they are striking back.Many teenagers like electronic games so much that they can’t stop playing. They spend hours tightly holding the joystick controls and constantly pressing buttons marked “fire”. They develop pains on their fingers because of the constant pressure. They play and play that the pains have no chance to cure properly. The rapid wrist movement required to guide the spaceship across the screen causes another problem: The muscles of the wrist and arm become so inflamed and swollen(充血红肿) that they press against the bones. This condition is what doctors now call “Space Warrior’s Wrist”.Other strange aches and pains also are likely to affect the elbows and shoulders.Another even more alarming problem is shown by the case of a 17-year-old girl which was recently reported in the British Medical Journal. She had been playing various kinds of electronic games for more than two hours a day. Her father repaired games and machines and she could use the cassettes and systems in his workshop as often as she liked. One day, after playing a game called Dark Invader, she lost consciousness(晕倒) and fell to the floor.Doctors who examined her found she was suffering from an unusual illness caused by lights flashing at a particular frequency.1. Electronic games are found very popular with _______.A. people living in townsB. students studying in high schoolsC. girls wo rking in their father’s workshopsD. young people2. “Space Warrior’s Wrist” is caused by _______.A. constantly pressing the buttonsB. rapidly moving across the screenC. tightly holding the joystick controlsD. inflamed and swollen muscles of the wrist3. The case of a 17-year-old girl given by the writer shows that the writer _______.A. supports playing electronic gamesB. feels very sorry for the girlC. disagreed with young people’s playing electronic gamesD. feels worried about young people’s poor health4. From the passage we can conclude that playing electronic games is _______.A. enjoyable and helpful to the studyB. exciting but harmful to the health and studyC. interesting but harmless to the eyesD. amusing and satisfyingPassage EightExperiments aboard the spaceship Columbia have disproved a theory on the human nervous system which won an Austrian professor a Nobel prize 79 years ago.West German astronaut Ulf Merbold disproved the theory during tests aboard the spaceship yesterday. His discovery is connected with the workings of the inner ear, the body’s balance mechanism(机制).In l914 Professor Robert Barany won the Nobel prize for Physiology(生理学) and Medicine when he announced that temperature differences affected the inner ear and caused the eyes to blink(眨眼). Histheory was accepted by scientists.But Merbold carried out tests to find if the theory was correct and shocked himself and space officials when he proved it wrong.According to Barany’s theory the eyes would blink when cold air was blown into one ear and hot air blown into the other.But if this theory was correct such a movement would be impossible in zero gravity.Both Merbold’s eyes cont inually blinked when the test was carried out.1. Tests were carried out in outer space in order to _______.A. find what causes the eyes to blinkB. shock the worldC. prove the theoryD. disprove the theory2. Barany’s th eory declared to prove _______.A. how our hearing mechanism worksB. why we constantly move our eyesC. that eye movement is affected by temperatureD. how hearing reacts(反应)3. Barany’s theory was proved incorrect in space by the effects of _______.A. having no weightB. having no airC. the pull of gravityD. hot and cold air streamsPassage NineScientists are developing a new kind of machine to take the place of humans. These machines can do jobs in places that are too dangerous for humans. For example, they are being developed to work in nuclear power center, deep under the oceans and in outer space.John Marrit, a psychologist(心理学家) in Williamsburg Massachusetts, helped develop the new machine. This is how they work. A machine is placed in an area far away from the person who operates it. The person wears special hard hat with television screens and sound equipment. The screens and sound equipment let the person see and hear exactly what the machine is seeing and hearing. Mr. Marrit says this gives the person the feeling of being in the same place as the machine. The idea, he says, is being there without going there. The person uses an electronic control to make the machine move. The machine copies the person’s m ovements exactly. If the person raises his right arm, the machine raises the right arm, too. This means an expert can do a dangerous job while staying in the safe place. For example, a person can direct the machine to destroy a bomb without going near the bomb himself.1. The new kind of machine being introduced in the passage is _______.A. in existenceB. only an ideaC. being tried outD. being researched and developed2. The machine _______.A. follows the perso n’s orderB. is controlled by a computerC. does exactly what the person doesD. is controlled by a television on the person’s head3. The difference between such a new machine and a robot is that _______.A. the new machine is more difficult to make than a robotB. the new machine is more difficult to be controlledC. a robot is controlled by man indirectlyD. a robot can’t be used in places too dangerous or farawayPassage Ten. HoneybeesHoneybees can do three kinds of jobs.The honeybee is one of the most unusual insects in the world. Bees are special because they divide up their work. Each bee has a certain job to do.The busiest bee is the worker. Workers build the nest, called a hive. Inside the hive, workers make a honeycomb from wax(蜂蜡). They store honey there for food. Workers are always cleaning and fixingthe hive. They even stand at the opening and fan their wings to cool the hive. Worker bees will attack anything—even people—to keep their hive safe.Another kind of bee is the drone(雄蜂). Drones are male bees, and their job is to fly with the queen bee and mate with her. After the queen mates, the worker bees drive the drones away. The drones then starve to death.The third kind of bee is the queen. Each hive needs only one queen, and her job is laying eggs. She can lay as many as 2, 000 eggs a day.1. The bee’s nest is called a _______.A. droneB. honeycombC. hiveD. wax2. Wax is used to make the _______.A. nestB. honeycombC. fanD. hive3. Which jobs do workers do?A. They lay 2, 000 eggs each day and build a nest.B. They mate with the queen bee and then starve.C. They clean the hive and keep it cool.D. They attack the queen bee.4. According to the story, bees _______.A. are very dangerous insectsB. will attack anything or anyone to protect the hive, if necessaryC. are like any other insect that fliesD. eat each other as food5. The drone is driven away when its job is finished, because _______.A. it attacked the workersB. it is no longer needed in the hiveC. the queen bee has diedD. it ate the queen beePassage ElevenAmerican doctors say that mothers who smoke cigarettes before their babies are born may slow the growth of their babies’ lungs. They say reduced lung growth could cause the babies to suffer breathing problems and lung disease later in life. Doctors in Boston, Massachusetts studied 1 100 children. The mothers of some of the children smoked, the other mothers did not. Doctors found that the lungs of the children whose mothers smoked were 8% less developed than the lungs of the children whose mothers did not smoke, and that the children whose mothers smoked developed 20% more cold and breathing diseases than other children later in life.Another recent study found that children had a greater chance of developing lung cancer if their mothers smoked. The study also showed that the danger of lung cancer increased only for sons and not for daughters, and that the father’s smoking did not affect a child’s chance of developing lung cancer.1. Mother who smokes before her child is born may _______.A. slow the growth of her baby’s lungB. cause her baby to suffer breathing problems and lung disease later in lifeC. make her child develop lung cancerD. All of above are right2. Doctors in Boston studied 1 100 children to _______.A. examine whether these children were healthyB. find out whether their mothers had smokedC. find why these children suffered breathing problems and lung diseaseD. look into the effect that mother’s smoking had on their children3. Suppose John’s father was a heavy smoker, so was Mary’s mother. According this passage, _______.A. John is more likely to develop lung cancerB. Mary is more likely to develop lung cancerC. John and Mary have the same chance to develop cancerD. neither John nor Mary has the chance to develop cancer4. This passage is to _______.A. warn us of the danger of smoking before childrenB. warn people with breathing problems not to smokeC. warn us that mothers who smoke may affect their children’s healthD. warn us that fathers who smoke may affect their children as mothersPassage TwelveYou can not see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples that can be seen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies. The moon, for example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in our direction. So moon light is only second hand sunlight.When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open.Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380 000 kilometers away, in only a little more than a second.1. You can see the book because_______.A. your eyes are close to itB. it reflects some of the sunlightC. it has light of its ownD. your eyesight can get to it2. The underlined word “luminous” means_______.A. visibleB. all colorsC. giving off lightD. sunlight3. ________ have light of their own.A. The sun and the moonB. The stars and the earthC. The sun and the starsD. The moon and the earth4. Which of the following is true?A. All the things you can see give off light.B. Light from the book is much shorter than that from the moon.C. The moment you open your eyes the light from the book travels to your eyes.D. Light travels so fast that there is no time for you to read.Passage ThirteenAs people continue to grow and age, our body systems(系统) continue to change. At a certain point in your life your body systems will begin to weaken. Your strength may become weaker. It may become more difficult for you to see and hear. The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury. In order to live longer, we have always tried to slow or stop this change that leads us toward the end of our lives.Many factors(因素) decide your health. A good diet plays an important role. the amount and type of exercise you get is another factor. Your living condition is yet another. But scientists studying agingproblem want to know: Why do people grow old? They hope that by studying the aging medical science they may be able to make the length of life longer.There is nothing to be afraid of as old age comes. Many consider the later part of life to be the best time for living. Physical activity may become less, but often you get better understanding of yourself and the world.What we consider old age now may only be middle-aged some day soon. Who knows, with so many advances in medical science happening so quickly, life length may one day be measured in centuries, rather that in years!1. When people become aging, they will lose some of their ability to bounce back from disease and injury, “bounce back” here means _______.A. to escape from disease and injuryB. to improve one’s health after one’s disease and injuryC. to jump backwardD. to run fast2. Many consider the later part of life to be the best time of living because ______.A. they consider their life has been a successful oneB. they have come through the battle of life safelyC. they have less misunderstanding of themselves and the outside worldD. they have nothing to do all day long only to watch their grandchildren growing up around them高一英语阅读理解试题〔科技类〕答案：A【答案与解析】本文讲电脑的发展历史。

There was a line at the fish counter, but only one staff person was there to take care of the customers. Some customers ordered quite an amount of fish for that staff person to work on. At last I was the second in line. All I wanted was a couple of crabs and should get out of there in no time.Noticing it was very busy at the fish counter, another staff person came over to help. I was ready to be served, but the staff person went to the end of the line and began to help a couple of ladies with snail (蜗牛). The customers in front of me, being served, turned around and looked at me sympathetically and the customer behind me called to the staff person, “You should star t here,” pointing at me. He was, well, ignored.If someone asked me, "What is the most important rule to follow in America?" I would reply without hesitation. "Wait your turn at all times." Wherever you go here in this country, you will find people waiting in a line quietly to get anything: whether in the supermarkets, department stores, bus stops, or gas stations, it's just a matter of waiting your turn. In a larger sense, "wait your turn" is more than just a guideline — it is a very basic rule that reflects the fundamental value of the western cultures. But in some situations your turn does not always come based on when you get there and how long you have waited in line, just like my case at the store. Even though this did not often happen, it did make me feel upset.（1）What happened to the author at the store?A.He was ill-treated by a customer.B.He wasn't served upon his order.C.He was asked to be served later.D.He was asked to do others a favor.（2）What does the underlined word "this" in the last paragraph refer to?A.His belief.B.His culture.C.His experience.D.His rule.（3）Why did the author write the text?A.To emphasize his kindness to others.B.To introduce some western cultures to us.C.To express his belief and his feeling.D.To show his disbelief in Queuing Rule.【答案】（1）B（2）C（3）C【解析】【分析】本文是一篇记叙文，讲述了作者在买螃蟹时排队很久，受到不公平待遇的经历，借此表现了西方文化的特点——要遵守次序，同时也表明了作者的感受和建议。

高中英语黄金阅读理解试题四(科技类)

高中英语黄金阅读Golden Reading for Senior Middle School Students四、科技类(1)Would you carry around an electronic ID, not in your pocket, but in your body? Does this idea scare you or make you feel safe?The first computer ID chip(芯片) that could be planted under a person’s skin might be marketed very soon.Developed by Applied Digital, an American technology company based in Florida, the device(发明物) could meet the need for public security(安全) after the September 11 attacks.For airports, nuclear power plants(核电站) and other high security facilities(设备), the immediate effects are obvious.The technology could help put an end to false ID cards, because it would be difficult to remove and copy a tiny computer chip. The chip is as small as a grain of rice.The technology would also allow satellites to track(追踪) a person’s every movement and store medical records.These uses are already attracting interest for tasks like fighting against kidnappings(绑架), or helping with medical operations.But some people are afraid of the loss of privacy(隐私).“You always have to think about what the device could be used for tomorrow,” said Lee Tien, a senior privacy lawyer in the United States.“At first a device is used for applications we all agree are good, but then it slowly starts being used for more than it was intended,” he said.However, Applied Digital says it will soon apply for(申请) government permission for the device. It says that the first people to use the chip will be volunteers.Getting the implant(需移植的芯片) would go something like this:A person or company buys the chip from Applied Digital for about US $ 200. And the company encodes(编码) it with the desired information.The customer then takes the chip to their doctor, who can plant it with a large needle.The device has no power supply, rather it is activated(使活动, 使运行) by a scanner(扫描仪) running across the skin above it. Without a scanner, the chip cannot be read.Even with the privacy concern, some are already eager to use the product.Jell Jacobs from Florida hopes to become the first buyer of the chip to store his medical records. Suffering from a serious illness, he wants to make sure doctors can help him quickly.Eight Latin American companies have also shown interests in the device. It could help to find any tourists who are kidnapped.1. The best title for the passage is _______.A. Why Is the New ID NecessaryB. Getting a New Kind of ID Under Your SkinC. An Advertisement for ChipsD. Where to Buy the Chip2. Which of the following is true according to the text?A. In some airports and factories such device is already being used.B. The information on the chip can be read when it has its power supply.C. The technology could help put an end to false ID cards.D. The first computer ID chip has already come into the market.3. What is the advantage with the electronic ID according to the passage?A. It can store people’s medical records and help with medical operations.B. With this people will have no fear of losing privacy.C. It’s cheap to buy and easy to get.D. It is developed by Applied Digital in Florida.4. What can we learn about Jeff Jacobs?A. He’s a worker in Applied Digital, a company in Florida.B. He’s a doctor who helps plant tile chips on people.C. He fears if he uses the chip he will lose privacy.D. He’s suffering from a serious illness and wants to buy the chip.【答案解析】本文介绍了新的个人身份证—电子身份证的特点、功能及人们对此的态度。

一、高中英语阅读理解1．阅读理解Your teenage best friend could be good for your long-term mental health, according to a new study published in the journal Child Development According to the findings, teenagers aged 15 to 16 who had a close friendship rather than a larger group of friends they were less close to had a greater sense of self-worth by the time they were 25 years old. Those people with a very close best friend were also less likely to experience depression and social anxiety, the study found. "Close friendship strength in mid-adolescence predicted relative increases in self-worth and decreases in anxiety and depressive symptoms by early adulthood, "the authors, led by Rachel K, Narr, a postdoctoral student focused on clinical psychology at the University of Virginia, wrote.A past research has suggested that adolescent friendships are important. Friendships during the teenage years predict academic success and improved mental health. But the new research further explores the type of friendships teenagers have. "My hunch(预感)was that close friendships compared to broader friendship groups and popularity may not function the same way," Narr told Quartz. "Being successful in one is not the same as being successful in the other." Many study participants did not continue to have a close relationship with their high-school best friend, leading the researchers to wonder what exactly was responsible for the mental health benefits. They suspected that the skills and ability to build such a friendship may be more important than the friendship itself.And as the researchers point out, those skills are not necessarily brought to bear in the world of social media. "As technology makes it increasingly easy to build a social network of shallow friends, focusing time and attention on developing close connections with a few individuals should be a priority," study co-author Joseph Allen said in a statement.（1）What is the benefit of having a close teenage friendship?A. Excellent performance in high school.B. A larger group of friends.C. Mental health by early adulthood.D. A large social network in the future.（2）What can we learn about the past research?A. It attached great significance to adolescent friendships.B. It was totally different from the new research.C. It helped improve teenagers' mental health.D. It compared broader friendship groups with popularity.（3）What did the researchers think might lead to the mental health benefits?A. Not continuing to have a close relationship.B. Having a best friend in high school.C. Understanding the world of social media.D. Knowing how to build a close friendship （4）What did the researcher Joseph suggest?A. Learning to use social media.B. Broadening your social circle.C. Improving the skills of making friends.D. Concentrating on high-quality relationship.【答案】（1）C（2）A（3）D（4）D【解析】【分析】本文是一篇说明文，研究发现，那些有非常亲密的好朋友的人也不太可能经历抑郁和社交焦虑。

It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owner to objects like their medication or a snack in the kitchen."RAS combines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected," said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.Currently, an estimated 50 percent of adults over the age of 85 need assistance with every day activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial strain on the healthcare system by making it easier for older adults to live alone.RAS is the first robot researchers have tried to incorporate into their smart home environment. They recently published a study in the journal Cognitive Systems Research that demonstrates how RAS could make life easier for older adults struggling to live independently."While we are still in an early stage of development, our initial results with RAS have been promising," Minor said. "The next step in the research will be to test RAS' performance with a group of older adults to get a better idea of what prompts, video reminders and other preferences they have regarding the robot."（1）How does RAS serve elderly people?A.

情景2 科技与生活Ⅰ.阅读理解A[2022·昆明市高三摸底诊断测试]Less than a quarter of families in Britain sit down for a “screenfree” dinner together every day away from TVs, phones and devices (设备), according to a research. The research was carried out to mark the launch of Vodafone Pro with Alexa, featuring a unique “Dinnertime” function which allows families to have 30 minutes of digital downtime.A study of 1，600 parents, with at least one child at home, found six in ten admit getting children to switch off their devices is the biggest cause of disagreements in their household, leading to an average of two quarrels a day. The research also found it takes almost ten minutes for a child to switch off their devices after being asked to.Almost all parents feel having a break from technology is important for family relationships. And 86 percent think dinner time is an important part of the day for spending quality time together. However, despite this, 93 percent of parents believe technology is important for a child's development, with 98 percent using digital devices to aid their learning.Dr. Anna Colton, clinical child psychologist, commented, “Technology plays a huge part in all of our lives, and improves our work, learning and leisure.” She added, “However, it is vital to ta ke time away from our screen and connect with family and friends facetoface, particularly at mealtimes — both for ourselves and for our relationships with loved ones, to develop relationships.”Max Taylor, consumer director at Vodafone UK, said, “30 minu tes is the proper amount of time for families to connect with one another away from screens, because it's long enough to have meaningful conversations, a meal or play a game—but not so long that it feels worrying or stressful.”1．Why do children often quarrel with their parents according to the text?A．They are unwilling to help with housework.B．They are urged to turn off digital devices.C．They are late for dinner with their parents.D．They are stressed with too much homework.2．What message does Dr. Colton mainly want to convey?A．Technology enables families to spend quality time.B．Screen time is of importance to children's learning.C．Facetoface communication can build good relationships.D．30 minutes is a proper time for mealtime communication.3．How does the author present the research findings?A．By providing some data.B．By giving some examples.C．By making a comparison.D．By analyzing the cause.4．Where can the text be found?A．In a textbook.B．In a science report.C．In a fashion magazine.D．In a travel brochure.B[2022·长春市普通高中质量检测(二)]On Tuesday, India's Prime Minister Narendra Modi launched a series of new highproducing crop varieties, including herbicidetolerant rice that can be directly planted into the soil, cutting the huge expenses on water and farm workers.In India, the world's biggest rice exporter, the traditional method of rice growing requires farmers to grow seeds in nurseries, and then wait for 20 to 30 days before transplanting the small plants by hand into the fields that are ankl edeep in water.With the new seed varieties developed by the staterun Indian Agricultural Research Institute, farmers only need to water the fields once to moisten (使变得湿润) the soil before planting the rice. Besides, the traditional method also uses a lot of water to control weeds as herbicides are costly and often do not distinguish between the rice and the unwanted weeds.Government scientists said the new rice varieties contain a gene that would allow farmers to spray a common, inexpensive herbicide without worrying about any side effects. “Our focus is very high on new seeds that can be adapted to new conditions, especially in changing climates，” Modi said.Water conservation is likely to be the main attraction of the new rice varieties in India, where farmers rely heavily on the monsoon (季风) rain. The traditional method uses 3，000 to 5，000 liters of water to produce 1 kg of rice. The new varieties could cut water use by at least 50% to 60%, farmers and government officials say. “For farmers like us, the main concern was the management of water, and the new varieties take care of that concern，” said Ravindra Kajal, who grows rice on his 9acre farmland in the northern state of Haryana. India is the world's secondlargest rice producer after China.5．Which is the benefit of the new rice?A．It can produce herbicides.B．It can be planted in any field.C．It needs a lot of water to grow.D．It can save money for farmers.6．Why can farmers apply a common herbicide to the new rice?A．The new rice contains herbicides itself.B．The herbicide is suitable for all rice varieties.C．The gene in the new rice can avoid harm from the herbicide.D．The herbicide can distinguish the rice from the weeds.7．What plays an important role in riceplanting in India?A．Water.

【英语】高三英语阅读理解试题经典及解析一、高中英语阅读理解1．阅读理解Have you ever experienced such an annoying thing as it took so long to open a web page? You're watching stops every few minutes, which ruined your internet experience. But it could be a thing of the past. On June 3, the Ministry of Industry and Information Technology announced that China would issue licenses for the commercialization of 5G. It means major telecom carriers will start to provide 5G services.The "G" in "5G" refers to the generation of mobile network technologies. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and the internet, and 4G made all of these things faster.Now 5G promises much faster data download and upload speeds, and more stable connections. This means that you will be able to download an entire HD movie in seconds and only experience a short delay between sending and receiving data. For example, when you have a video chant with your friend, there is generally a 100 to 200 milliseconds (毫秒) delay with 4G, but 5G will reduce the delay to 1 millisecond or less, which is almost real time.With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid potential dangers. Meanwhile, 5G enabled wearable devices will keep doctors constantly updated on the health status of their patients and warn them immediately if there's something wrong. Besides, VR games will become more popular with 5G. The short delay of 5G will make the games feel even more real.Though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not "travel" far. On 4 networks, you can be 10 kilometers away from the nearest transmission (传输) base and barely lose signal. But 5G will only cover about 300 meters, meaning we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new specially, designed for 5G that are currently expensive.（1）What is the function of the first paragraph?A.To provide a background of the topic.B.To offer basic knowledge of the topic.C.To use an example to support the topic.D.To draw readers' attention to the topic.（2）According to the passage, what is likely to happen to our life with 5G?A.Doctors can treat more patients.B.No drivers are needed in the near future.C.Many advanced technologies will be further improved.D.Children will hate playing VR games in the real world.（3）What can he found when 5G is compared with 4G?A.4G cover smaller areas.B.4G needs more transmitters.C.5G signals can travel farther.D.5G costs higher in early stage.（4）What is the text mainly about?A.The development of 5G.B.Challenges that 5G will face.C.Benefits that people will get from 5G.D.The difference that 5G will make to our lives.【答案】（1）D（2）C（3）D（4）D【解析】【分析】本文为一篇说明文，介绍了5G时代的到来即将给人们的生活带来的影响。

It will be the first area in the world to use the technology to punish drivers distracted (分心) with telephone calls, social media or text messages.Road Safety experts are concerned about the growing number of accidents involving drivers using smart phones on the state's roads. They say drivers who use phones while driving greatly increase their chances of being involved in an accident.The New South Wales government plans to place 45 Mobile Phone Detection Cameras across the state by December. Each phone detection unit contains two cameras. One camera takes pictures of a vehicle's registration plate (牌照). A second camera looks through the front window of a car or truck to see what drivers are doing with their hands.The units use artificial intelligence to set aside drivers who are not touching their phones. Human beings then confirm if the pictures show illegal behavior before notice is sent to the vehicle's registered owner. A violation (违反) carries fine of $232. Some cameras will be permanently set up on roadsides. Others will be moved, from time to time, around the state.Two fixed cameras took photographs of 8.5 million vehicles as part of a six-month test earlier this year. The cameras took photos of more than 100,000 drivers with their hands on phones. One driver was using a phone and another electronic device, an Apple iPad, at the same time. Another driver had a passenger guide the vehicle while they both held phones, the state government said.（1）What is the real purpose to set up cameras in New South Wale?A.To keep records of the accidents.B.To promote the latest technology.C.To find illegal behavior of the drivers.D.To force drivers to focus more on driving.（2）What can we infer from the road safety experts?A.Smart-phones are main killers on the road.B.All accidents result from drivers' using cell-phones.C.Measures are badly needed to ban using phones while driving.D.Carrying a smart-phone while driving will cause an accident.（3）How does the phone detection unit function effectively?A.It corrects the drivers' wrong behavior.B.It has two cameras to record the plates.C.It sends a notice to the legal diver autonomously.D.It combines artificial intelligence with human's efforts.（4）What did a six-month test show?A.Electronic devices could help divers indeed.B.Mary passenger helped operate the vehicles.C.Many drivers used electronic devices while driving.D.It was common to be busy with two wireless devices.【答案】（1）D（2）C（3）D（4）C【解析】【分析】本文是一篇说明文，介绍了澳大利亚新南威尔士州正在设置摄像头，以减少开车时全神贯注于无线设备的人数。

高考英语压轴专题《高中英语阅读理解》难题汇编百度文库

一、高中英语阅读理解1．阅读理解It seems that electronic devices just keep getting smaller. Scientists in the United States have announced the creation of the first transistor with only two dimensions(二维).A transistor is a small electronic device that transfers or carries electronic current. Scientists hope these new 2D transistors will be used for building high-resolution(高分辨率)displays that need very little energy.Two groups of scientists created these 2D transistors. They report that the transistors are only a few atoms thick.Usually transistors are made with the element silicon(硅). Computer processors, memory chips, TV screens and other electronic devices contain billions of silicon-based transistors. But these very small electrical parts have certain limitations.Dimitris Ioannou is an electrical engineering professor at George Mason University. He says the traditional transistor has been improved as much as it can be. He adds that researchers have been looking for new materials with special features and they want transistors to be seen through and soft."If the layers are very thin, the transistor can become flexible, so it doesn't have to be rigid(坚硬的), like it would be in a silicon chip. So people can think of applications like wearable electronics, television screens and other things," said Ioannou.These new transistors can also carry higher current.

高中英语阅读理解科技类五

高中英语阅读理解科技类五LONDON (Reuters)-Organic fruit, delivered right to the doorstep. That is what Gabriel Gold prefers, and he is willing to pay for it. If this is not possible, the 26-year-old computer technician will spend the extra money at the supermarket to buy organic food.“Organic produce is always better,” Gold said. “The food is free of pesticides(农药)，and you are generally supporting family farms instead of large farms. And more often than not it is locally grown and seasonal, so it is more tasty.” Gold is one of a growing number of shoppers buying into the organic trend, and supermarkets across Britain are counting on more like him as they grow their organic food business. But how many shoppers really know what they are getting, and why are they willing to pay a higher price for organic produce? Market research shows that Gold and others who buy organic food can generally give clear reasons for their preference-but their knowledge of organic food is far from complete. For example, small amounts of pesticides can be used on organic products. And about three quarters of organic food in Britain is not local but imported to meet growing demand. “The demand for organic food is increasing by about one third every year, so it is a very fast-growing market,” said Sue Flock, a specialist in this line of business.1. More and more people in Britain are buying organic food because _______.A. they are getting richerB. they can get the food anywhereC. they consider the food free of pollutionD. they like home-grown fruit2. Which of the following statements is true to the facts about most organic producesold in Britain?A. It grows indoors all year round.B. It is produced outside Britain.C. It is grown on family farms.D. It is produced on large farms.3. What is the meaning of “the organic trend” as the words are used in the text?A. growing interest in organic foodB. better quality of organic foodC. rising market for organic foodD. higher prices of organic food4. What is the best title for this news story?A. Organic food-healthy, or just fo r the wealthy?B. The making of organic food in Britain.C. Organic food-to import or not?D. Good qualities of organic food.BDeserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks’ time. Ten inches of rain may be enough for many plants to survive(存活) if the rain is spread throughout the year, If it falls, within one or two months and the rest of the year is dry, those plants may die and a desert may form.Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes(沙丘) are formed as winds move the sand across the desert. Bit by bit, the dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high.There is, however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs(悬崖) and deep valleys were formed from thick mud that once lay beneath a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand, rain, heat and cold all wore away at the remaining rocks. The faces of the desert mountains are always changing — very, very slowly — as these forces of nature continue to work on the rock.Most deserts have a surprising variety of life. There are plants, animals and insects that: have adapted to life in the desert. During the heat of the day, a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely.5. Many plants may survive in deserts when ______.A. the rain is spread out in a yearB. the rain falls only in a few weeksC. there is little rain in a yearD. it is dry all the year round6. Sand dunes are formed when______.A. sand piles up graduallyB. there is plenty of rain in a yearC. the sea has dried up over the yearsD. pieces of rock get smaller7. The underlined sentence in the third paragraph probably means that in a desert there is______.A. too much sandB. more sand than beforeC. nothing except sandD. something else besides sand8. It can be learned from the text that in a desert______.A. there is no rainfall throughout the yearB. life exists in rough conditionsC. all sand dunes are a few feet highD. rocks are worn away only by wind and heatCB A A A ADB。

科技英语阅读课文翻译UNIT1-8

科技英语阅读1-8单元译文：Unit 1罗素悖论的提出是基于这样的一个事例：设想有这样一群理发师，他们只给不给自己理发的人理发。

假设其中一个理发师符合上述的条件，不给自己理发；然而按照要求，他必须要给自己理发。

但是在这个集合中没有人会给自己理发。

（如果这样的话，这个理发师必定是给别人理发还要给自己理发）1901年，伯特兰·罗素悖论的发现打击了他其中的一个数学家同事。

在19世纪后期，弗雷格尝试发展一个基本原理以便数学上能使用符号逻辑。

他确立了形式表达式（如：x =2）和数学特性（如偶数）之间的联系。

按照弗雷格理论的发展，我们能自由的用一个特性去定义更多更深远的特性。

1903年，发表在《数学原理》上的罗素悖论从根本上揭示了弗雷格这种集合系统的局限性。

就现在而言，这种类型的集合系统能很好的用俗称集的结构式来描述。

例如，我们可以用x代表整数，通过n 来表示并且n大于3小于7，来表示4，5,6这样一个集合。

这种集合的书写形势就是：x={n：n是整数，3<n<7}。

集合中的对象并不一定是数字。

我们也可让y={x：x是美国的一个男性居民}。

表面上看，似乎任何一个关于x的描述都有一个符合要求的空间。

但是，罗素（和策梅洛一起）发现x={a：a不再a中}导致一个矛盾，就像对一群理发师的描述一样。

x它本身是在x的集合中吗？否定的答案导致了矛盾的出现。

当罗素发现了悖论，弗雷格立即就发现悖论对他的理论有致命的打击。

尽管这样，他还不能解决这个问题,并且上世纪有很多的尝试，去解决这个问题（但没有成功）。

罗素自己对这个悖论的回答促进了类型理论的形成。

他解释说，悖论的问题在于我们混淆了数集和数集的集合。

所以，罗素介绍了对象的分级系统：数、数集、数集的集合等等。

这个系统为形式化数学的形成奠定了基础，至今它还应用于哲学研究和计算机科学分支。

策梅洛对于罗素悖论的解决方法用新的公理：对于任意公式A（x）和任意集合b，都会有一个集合满足y={x：x既在b中又满足A（x）}取代了以前的公理：对于任意公式A（x），都会有一个集合满足y={x：x满足A（x）}。

(英语)英语阅读理解练习题含答案及解析

（英语）英语阅读理解练习题含答案及解析一、高中英语阅读理解1．阅读理解A new study has shown how computers and robots powered by artificial intelligence can read human eye movements to "read" human personalities.The eyes, they say, are the windows to the soul. And if that is true, computers and robots powered by sophisticated(复杂的)artificial intelligence algorithms(算法)may soon have the ability to peer into your soul. That is the result of a new study on the connection between eye movements and personality, conducted by neuroscience researchers based at the University of South Australia and Published in the scientific Journal Frontiers in Neuroscience."Eye movements during an everyday task predict aspects of our personality," wrote the researchers, led by University of South Australia neuroscientist Tobias Loetscher, whose team follows 42 study subjects around the university campus recording their eye movements, then determines their personality traits(特点)with "well-established questionnaires" for determining personality type, according to a summary of the study published by the site Science Daily.The researchers fed the data into their Al algorithms and found that computers running the algorithms were able to record human eye movements and immediately determine a person's major personality traits, such as "neuroticism, extraversion(外向)，agreeableness, conscientiousness, as well as perceptual(感知的)curiosity", the scientists wrote."The new findings could improve the way human beings interact with their computers and other high-tech devices, even robots, allowing for more natural and realistic social interactions with machines," Loetscher said."People are always looking for improved, personalized services. Today's robots and computers are not socially aware so they cannot adapt to non-verbal information," Loetscher said in a statement quoted by Indian Express. This research provides opportunities to develop robots and computers so that they can become more natural, and better at interpreting human social signals."The study revealed previously undiscovered relations between specific personality characteristics and specific eye movement tendencies, according to a summary in Britain's Daily Mail newspaper.（1）What do the underlined words "peer into" in Paragraph 2 probably mean?A.understandB.stare atC.search forD.concern about（2）How did the researchers conduct the research?A.It was carried out in a lab.B.42 subjects' eye movements were recorded.C.The students' daily movements were tracked.D.Its subjects' personalities were determined by computer.（3）According to Tobias Loetscher, what can we know?A.Robots and computers are socially conscious.B.People care less about improved, personalized services.C.Today's robots and computers can accustom to non-verbal information.D.The discovery will improve the interaction between human beings and machines.（4）What can be a suitable title for the text?A.Human Personality TraitsB.What Human Eye Movements AreC.Tell Personalities by Eye Movements.D.How Humans and Machines Interact【答案】（1）A（2）B（3）D（4）C【解析】【分析】本文是一篇说明文，一项新的研究表明，由人工智能驱动的计算机和机器人可以通过阅读人类的眼球运动来“解读”人类的性格。
