高三英语阅读理解题训练及答案详解第一篇：Imagine a mass of floating waste is two times the size of the state of Texas. Texas has a land area of more than 678 000 square kilometers. So it might bedifficult to imagine anything twice as big.All together, this mass of waste flowing in the North Pacific Ocean is known as the Great Pacific Ocean Garbage Patch. It weighs about 3 500 000 tons. The waste includes bags，bottles and containers—plastic products of all kinds.The eastern part of the Great Pacific Ocean Garbage Patch is about l 600 kilometers west of California. The western part is west of the Hawaiian Islands and east of Japan. The area has been described as a kind of oceanic desert，with light winds and slow moving water currents. The water moves so slow that garbage from all over the world collects there.In recent years，there have been growing concerns about the floating garbage and its effect on sea creatures and human health. Scientists say thousands of animals get trapped in the floating waste，resulting in death or injury. Even more die from a lack of food or water after swallowing pieces ofplastic. The trash can also make animals feel full，lessening their desire to eat or drink.The floating garbage also can have harmful effects on people. There is an increased threat of infection of disease from polluted waste，and from eating fish that swallowed waste. Divers can also get trapped in the plastic.Its existence first gained public attention in l997. That was when racing boat captain and oceanographer Charles Moore and his crew sailed into the garbage while returning from a racing event. Five years earlier，another oceanographer learned of the trash after a shipment of rubber duckies got lost at sea. Many of those toys are now part of the Great Pacific Ocean Garbage Patch.In August，2009，a team from the University of California，San Diego became thelatest group to travel to it. They were shocked by the amount of waste they saw. They gathered hundreds of sea creatures and water samples to measure the garbage patch’s effec t on ocean environment.51.How did the writer introduce the topic of the passage?A. By giving an example.B. By listing the facts.C. By telling a story.D. By giving a parison.52.What do we know about the Great Pacific Ocean Garbage Patch?A. It is made up of various kinds of plastic products.B. It is a solid mass of floating waste materials.C. It lies l60 000 kilometers east of California.D. It is described as a kind of oceanic desert.53.Why do people pay attention to the Great Pacific Ocean Garbage Patch?A. Because it may prevent the flow of ocean water.B. Because the polluted plastic articles will move up the food chain.C. Because it may be from an island in the pacific.D. Because ships may be trapped in the floating waste.54.Which column can you find the passage on a newspaper?A. Sports and entertainment.B. Media and culture.C. Environment and society.D. Science and technology.55.The purpose of writing this passage isto____________.A. warn people of the danger to travel in the pacificB. analyze what caused the waste patch in the pacificC. give advice on how to recycle waste in the oceanD. introduce the Great Pacific Ocean Garbage Patch第二篇：Europeans should try to stay indoors if ash from Iceland's volcano starts settling, the World Health Organization warned Friday as small amounts fell in Iceland, Scotland and Norway.WHO spokesman Daniel Epstein said the microscopic(微小的) ash is potentially dangerous for people when it starts to reach the Earth because inhaled(吸入) particles can enter the lungs and cause respiratory problems. And he also said Europeans who go outside might want to consider wearing a mask.Other experts, however, weren't convinced the volcanic ash would have a major effect on peoples' health and said WHO's warnings were "hysterical." They said volcanic ash was much less dangerous than cigarette smoke or pollution. Volcanic ash is made of fine particles of fragmented volcanic rock. It is light gray to black and can be as fine as talcum powder. During a volcanic eruption, the ash can be breathed deep into the lungs and cause irritation even in healthy people. But once it falls from a greater distance — like from the cloud currently hovering above Europe — its health effects are often minimal, experts say."Not all particles are created equal," said Ken Donaldson, a professor of respiratory toxicology at the University of Edinburgh, "In the great scheme of things, volcanic ash is not all that harmful." And he said most Europeans' exposure to volcanic ash would be negligible and that only those in the near districts of the Icelandic volcano would likely be at risk.Dr. Stephen Spiro, a professor of respiratory medicine and deputy chair of the British Lung Foundation, said the further the particles travel, the less dangerous they will be. "The cloud has already passed over northern Scotland and we haven't heard of any ill effects there," he said. Spiro said to wear masks or stay indoors to avoid volcanic ash was "over the top" and "a bit hysterical."60. The text is mainly about .A. the effect of volcanic ashB. the health risk of volcanic ashC. the disadvantages of volcanic ashD. the opinions on health risk of volcanic ash61. Which one is true according to Paragraph3?A. The volcanic ash’s effects on Europeans were little.B. The ash caused irritation even in healthy people.C. Other experts thought WTO’S warnings were useful.D. The volcanic ash was more dangerous than cigarette smoke or pollution.62. The underlined word “hysterical” in Paragraph4 most probably means .A. amazingB. practicalC. valuableD. overstated63. What can we learn from the passage?A. The volcanic ash wouldn’t be harmful to people.B. All experts thought the volcanic ash did great harm to our health.C. People close to the volcano would likely be at risk according to some experts.D. Europeans should stay indoors because Iceland's volcano starts settling.第一篇：51.D。

And Julie Andersen of the Plastic Oceans Foundation says what we see is just the ti p of the problem. “Half of the waste actually sinks to the bottom, and that remains on the surface actually breaks down. ”The filmmakers found rubbish in ocean gyres, the circulating currents that trap large concentrations of pollution in the Atlantic, Indian, and Pacifc Oceans, home of what some have plastic. What we found was a plastic smog that spread throughout all the water. And in some parts of the oceans, scientists have found more plastic than plant. ”The pieces of the plastic garbage infect the food chain, sometimes visibly, and more so at the microscopic level, where the plastic particles interact with other pollutants. “There are heavy metals, medicines, industrial waste in the sea, while it acts like magnets(磁铁). These poisonous substances absorb on the plastic, and then when seafood absorbs the plastics, those poisonous substances enter the fatty tissues. ”To be consumed by other sea life and by people at last. China, Indonesia, the Philippines, Thailand and Vietnam are the worst plastic polluters. The United States, although a leader in recycling, is one of the world's 20 since it produces and consumes so much plastic. There are efforts around the world to address the problem, including at this newly opened recycling center in Lebanon(黎巴嫩). But Andersen says there is more that people can do. “Cut back on single-use plastics, straws, plastic cups, plastic water bottles, plastic bags and find alternatives like reusable materials.” She says healthy oceans are essential to our survival.（1）What can we learn from the passage?A.

She wants to find her future husband through this way.The unnamed husband seeker who sent out the email had just finished reading the best-selling book named Lean In. It was 11 p.m. on a Sunday night and she realized this was the second self-help book she had read in the month. She was still single. Things were not looking fine, but there was hope for her still. If the book had taught her anything, it was that she needed to take a more positive role in finding love. After all, if she wanted to get a better job, she wouldn't just sit outside an employer's building and wait for someone to offer it to her, so why should finding a husband be any different?

（英语）高考英语阅读理解题20套（带答案）及解析（英语）高考英语阅读理解题20套(带答案)及解析一、高中英语阅读理解1．阅读理解One of the biggest problems when we are talking is the awkward silence. Encountering this situation is so uncomfortable that you would avoid meeting new people in the first place. In the past, I struggled wit h this and I even thought it had to do with my DNA or something… But later I learned that once you know how to keep those words flowing, you can meet and talk to anyone you like, which helps create great possibilities for friendship, fun and shared activities that you would otherwise have missed out on.After studying this in depth, I had different opinions and found that one of these common behaviors is the habit of filtering (过滤)--holding back from saying something until you've "checked" to make sure that what you're about to say is cool, impressive and interesting. Another problem is not learning to get in the mood for conversation. If you don't know how to change from subjects, then it can take a lot of time to warm up.It is the reflex (习惯性思维) that allows you to say whatever goes on in your mind. It's fun to realize that you're allowed to say whatever is on your mind. As long as you don't say anything that could land you in jail (监狱).All of the "Oh! That's interesting…" "Hmm, I've never heard of that" "Hmm, cool!" expressions are reactionary (保守的) bits of conversation that prove to the other person that you're really listening. This works 99% of the time. So, if you show some interest, they'll hang around and want to talk to you even more.Everyone knows that stories juice-up conversations, but most people only talk about stories of their own lives. When someone mentions something related to any of them, just tell the story, even if it's not from your life. The more interesting, stranger or more frightening they are, the harder they are to forget.（1）If people can deal with the awkward silence, they can .A. train their working skillB. improve their life qualityC. enrich their social lifeD. establish their working relationship（2）When talking with others, we should .A. feel nervousB. think twiceC. be free to expressD. avoid breaking in （3）According to the passage, what do the speakers care much about?A. The attractive topics of conversation.B. The atmosphere of the conversation.C. The listener's experiences and tastes.D. The listener's curiosity and concern.（4）What does the underlined part "juice-up conversations" mean?A. making conversations more boringB. making conversations livelierC. making conversations smootherD. making conversations more relaxing【答案】（1）C（2）C（3）D（4）B【解析】【分析】本文本文是一篇议论文，我们谈话时最大的问题之一是尴尬的沉默。

A new technology is going to ripe,one that could transform our daily lives,help to form new industries,even remove world economic powers from their present positions.Unlike the wave of industrialization that began in the West and spread later to the rest of the world,the new developments are taking place in research labs all over the globe—and Asians are in the forefront. Physicists are creating a new class of materials that display an amazing property unforeseen even two years ago—superconductivity(超导体技术).Used today only in specialized equipment,super conductors have the potential to radically change most of the electrical and electronic appliances found in the home,making them smaller, more powerful and efficient. They could free our cities of pollution by replacing petrol and diesel (柴油) vehicles with electric cars, and cut the cost of electricity.The new materials do something that even the best of conductors such as copper and silver cannot—they do away with all electrical resistance.The significances for energy storage are great.The technology is in its early stage, still accessible to countries that decide to invest brains and money. For75 years it had remained little more than a scientific curiosity with limited practical use because the phenomenon occurred only at extremely low temperatures. It was first observed in1911by a Dutch scientist named Heike Kamerlingh Onnes,who cooled mercury(水银)to temperatures below-269℃with liquid helium(氦).Then in January last year, two IBM scientists, K. Alex Muller and J.George Bednorz,found a metal oxide ceramic(氧化陶瓷)that superconducted at-243℃.Their report went largely unnoticed until last December,when it was confirmed at a scientific meeting in Boston.Today Japan, India, China and other Asian countries all have their share of experts who spend their days and nights in labs, acting as midwives( 助产士) to a new technology.（1）As is indicated in the passage,the technology of superconductivity____________.A.has already been developedB.is still under developmentC.will be used only in specialized equipmentD.will be used in daily lives in a few years（2）The new technology differs from the others in that ____________.A.it began in the East and spread later to the rest of the worldB.it began in the West and spread later to the rest of the worldC.it is being cultivated in research labs around the worldD.it is accessible to physicists who are intelligent and rich（3）From the passage,we may conclude that____________.n scientists gain the lead in the growth of the new technologyB. Dutch scientists kept reporting new findings for the last 75yearsC.IBM scientists'report receive immediate attention all over the worldD.the West was astonished at the new technology developed by the Asians（4）Which of the following would be the best title for the passage?A.The Prospect of a New TechnologyB.Superconductivity:A New TechnologyC.A New Technology:The Key to Change the Way of Our LivesD.A New Technology:A Joint Effort of Many Countries【答案】（1）B（2）C（3）A（4）B【解析】【分析】本文是一篇说明文，介绍了超导体技术的发展潜能和发展状况。

【英语】高考英语阅读理解题20套(带答案)及解析一、高中英语阅读理解1．阅读理解Experts note that an unhealthy lifestyle can put you at great risk of heart disease and stroke. So doctors urge us to eat healthy foods, get exercise, stop smoking and limit our alcohol intake. But there is something else you can do. And it is free and easy. Smile!Dr. Chockalingam, a heart disease specialist in Columbia, advises his patients to smile. He says a smile may be one way to help your heart. "When we smile, the brain wiring changes. The chemicals that are released are more positive." He says smiling is the first step in fighting physical and emotional stress and its sometimes harmful effects on human health. This is not just New Age advice. Several studies support his opinion.When you feel stressed or under pressure, your body releases many natural hormones (荷尔蒙) including adrenaline and cortisol. Adrenaline increases your heart rate and blood pressure. Cortisol is the body's main stress hormone. It increases sugar in the bloodstream. If you are truly in danger, these hormones can help you. They are part of what we call our fight-or-flight response. However, when we are stressed for a long period, these stress hormones are ever-present in our bodies. And that, medical researchers warn, may lead to health problems.Researchers say the connection between stress and heart disease is still unclear. However, they claim that when people are stressed for long periods of time, they may have an unhealthy lifestyle, which can lead to health problems.Dr. Chockalingam says a smile may be one way to help. He tells his patients to smile 20 times an hour. To some, that might seem like a lot of smiling. Or some might even feel foolish ... smiling for seemingly no reason. But a smile does not involve drugs. It is not invasive like a surgical operation. It is free and it has no bad side effects."Once people smile, they are relaxing. This relaxation directly lowers blood pressure, improves sugar levels in the blood. If we are smiling, we are breaking that link between stress and health." And it just may provide a little extra protection to everyone's heart health.（1）Which of the following agrees with Dr. Chockalingam's opinion?A.Smile has the same effects as laughter.B.Smile can be used to take the place of medicine.C.Smile is better than any healthy lifestyle to health.D.Smile can make our body produce beneficial chemicals.（2）What can we know about the mentioned stress hormones?A.They can lower our blood pressure.B.They will surely lead to heart diseases.C.They can benefit us when we are in danger.D.They will make us live an unhealthy lifestyle.（3）Why does Dr. Chockalingam think smiling is helpful to our health?A.It can make us relax.B.It increases sugar levels.C.It has little bad side effects.D.It can happen for no reason.（4）What can be the best title for the text?A.A Thorough Analysis of the Causes of Heart DiseasesB.One Thing You Can Do Right Now to Help Your HeartC.One Thing That Is Closely Connected with Stress HormonesD.The Clear Connection Between Unhealthy Lifestyles and Heart Diseases【答案】（1）D（2）C（3）A（4）B【解析】【分析】本文是一篇说明文，哥伦比亚的心脏病专家Chockalingam博士建议多保持微笑，他认为微笑可能是帮助心脏的一种方式。

高三英语阅读理解题20套(带答案)一、高中英语阅读理解1．阅读理解Generally speaking, government regulations normally ban anything from smoking in public places to parking in certain zones. But officials in the Brazilian town of Biritiba Mirim, 70km (45miles) east of Sao Paulo, have gone far beyond that. They plan to prohibit residents from dying early because the local cemetery(墓地) has reached full capacity.There's no more room to bury the dead, they can't be cremated(火化) and laws forbid a new cemetery. So the mayor has proposed a strange solution: outlaw death. Mayor Roberto Pereira says the bill is meant as a protest against federal regulations that prohibit new or expanded cemeteries in preservation areas. "They have not taken local demands into consideration", he claims.A 2003 decree(法令) by Brazil's National Environment Council forbids burial grounds in protected areas. Mr. Pereira wants to build a new cemetery, but the project has been stopped because 98% of Biritiba Mirim is considered as a preservation area.Biritiba Mirim, a town of 28,000 inhabitants, not only wants to prohibit residents from passing away. The bill also calls on people to take care of their health in order to avoid death. "I haven't got a job, nor am I healthy. And now they say I can't die. That's ridiculous," Amarido do Prado, an unemployed resident said.The city council is expected to vote on the regulation next week. "Of course the bill is laughable, illegal, and will never be approved," said Gilson Soares de Campos, an assistant of the mayor. "But can you think of a better resolution to persuade the government to change the environmental decree that is prohibiting us from building a new cemetery?" The bill states that "offenders will be held responsible for their acts." However, it does not say what the punishment will be.（1）What is the bill to be proposed by the officials in Biritiba Mirim?A. Ban on building a new cemetery.B. Ban on parking in certain zones.C. Forbidding buried grounds in preservation.D. Prohibiting residents from dying early.（2）What can we infer from the phrase "have gone far beyond that" in the first paragraph?A. The officials in Biritiba Mirim have made these regulations.B. The officials in Biritiba Mirim have been to many places around the world.C. The bill to be proposed by officials in Biritiba Mirim is much too unexpected.D. The officials in Biritiba Mirim have built too many cemeteries in their town.（3）What's the attitude of the mayor of Biritiba Mirim towards the federal regulations? A. He gives strong backing to them. B. He objects to them.C. He remains silent about them.D. He asks the residents for advice on them.（4）Which of the following is TRUE according to the text?A. The bill has come into effect but it doesn't state clearly what punishements the offenders will receive.B. The residents of the town sing high praise for the bill.C. The government is going to change the unreasonale and laughable decree.D. No betterresolution of the problems has been thought out.【答案】（1）D（2）C（3）B（4）D【解析】【分析】本文是一篇新闻报道，由于墓地短缺，巴西城市Biritiba Mirim的官员草拟了一份不准人过早的死去的法案，这引起了当地居民的争论。

【英语】高三英语阅读理解题20 套( 带答案 ) 含解析一、高中英语阅读理解1．阅读理解Scientists have discovered a "monster black hole" so massive that, in theory, it shouldn't exist. It's a stellar black hole —the type that forms after stars die, collapse, and explode. Researchers had previously believed that the size limit was no more than 20 times the mass of our sun because 8S these stars die, they lose most of their mass through explosions that expel matterand gas swept away by stellar windsThis theory has now been toppled by LB-1, the newly discovered black hole. Located about15.000 light years away, it has a mass 70 times greater than our sun, according to a press releasefrom the Chinese Academy of Sciences.The findings were published by Chinese researchers in the journal Nature on Wednesday. "Black boles of such mass should not even exist in our galaxy, according to most of the currentmodels of stellar evolution," said Liu Jifeng, head of the team that made the discovery. "LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challengeof explaining its formation."Scientists are now scratching their heads at how LB-1 got so huge.The Chinese team has proposed a number of theories. LB-1' sheer size suggests that it "was not formed from the collapse of only one star," the study said—instead, it could potentially be twosmaller black holes orbiting each other.Another possibility is that it formed from "fallback supermova." This is when a supernoma—the last stage of an exploding star —ejects material during the explosion, which then falls backinto the supernova, creating a black hole.This fallback formation is theoretically possible but scientists have never been able to prove or observe it. If this is how LB-1 formed, then we may have "direct evidence for this process" for the first time, the study said.There are several types of black holes and stellar black holes like LB-1 are on the smaller side,according to NASA. Supermassive black holes are much bigger — they can be billions of times themass of our sun,Scientists believe supermassive black holes may be connected to the formation of galaxies, as they often exist at the center of the mass star stems but it is still not clear exactly how, or which form first.（1） Why does the writer write the article?A.To report the great achievement Chinese scientists have made in black hole theory,B.To inform the readers of the basic knowledge about the black hole,C.To share with the readers the new development of the black hole discovery,D.To demonstrate the significance of discovering new black holes for science.（2） Which of the following about LB-1 is true to the passage?A.It is the biggest black hole ever discovered.B.It lost only a small part of its mass through explosion.C.It couldn't have been formed from the collapse of one star.D.Its discovery may lead to some breakthrough in the "fallback formation theory".（3） Which of the following is right according to the passage?A.If the sun in our galaxy dies some of its mass will be taken away by stellar winds.B.A massive supernova will be formed and then exploded if the sun in our galaxy dies.C."The Milky Way" was formed after a supermassive black hole collapsed and exploded.D.If "the Milky Way" dies, a supermassive black hole will be formed after its death.【答案】（ 1） C（2） D（3） A【解析】【分析】本文是一篇新闻报道，报道了科学家们已经发现了一个“巨型黑洞”，其质量之大，在理论上是不应该存在。
