高考英语阅读理解训练题及答案解析（4篇）高考英语阅读理解训练题及答案解析 1To Richard Dorsay, a 36-year-old homeless Chicagoan. it was, at last, a place to call his own But to everyone else. it was the Lake Shore Drive road bridge, so when Chicago city authorities discovered Dorsay living inside the bridge's steel s1ructurc last month. they had no choice but to drive him away.He had been living in the bridge for three years. lie also furnished it with a television, a microwave and a PlayStation, and borrowed power from the municipal(市政的)electricity supply. But that wasn't the most extraordinary thing. The most extraordinary thing was that the Lake Shore Drive Bridge is a drawbridge.“The first time, it was scary," Dorsay told a reporter from the Chicago Sun-Times, recalling how a bell would ring and his home would tip into the air, allowing ships to pass along the Chicago River below. "After that, it was almost like riding a ferry's wheel." Brian Steele, a spokesman for the Chicago Department of Transportation, puts it more straightforwardly. "Essentially," he says, "it changed his living space from horizontal(水平的) to vertical. "Dorsay had a history of homelessness and emotional problem. but inthe bridge. he thought, he had finally found a kind of stability. "You've got to be kind of agile(敏捷的)," he admitted. "But it doesn't take genius to figure out what to do. " Dorsay is now without a home, though he is currently staying with his parents. Gary, his father, said,"I've always hoped that he would find a place and he would seek employment. He is strong enough and bright enough to do something."(B) 24. According to Richard Dorsay, why did he like living in the bridge?A. It was free.B. He felt more secure there.C. It was an extraordinary thing.D. He liked scary things.推理题。
高考英语综合题专练∶阅读理解含答案(1)
一、高中英语阅读理解1．阅读理解City trees grow faster and die younger than trees in rural forestry, a new study finds. Over their lifetimes, then, urban trees will likely absorb less CO2 from the air thah forest trees.As we all know, the earth would be freezing or burning hot without CO2. However, CO2is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burning-of fossil(化石)fuels, have been sending extra greenhouse gases into the air. This has led to a rise in average temperatures across the globe.Studies had shown forests readily absorb CO2, but there hadn't been much data on whether city trees grow, die and absorb CO2at the same rate as forest trees do. So some researchers decided to find out.To figure out how quickly trees were growing, researchers tracked their diameters (the width of their trunks) between 2005 and 2014. A tree's diameter increases as it grows, just as a person's waist size increases as they gain weight. About half the weight of a tree is carbon, research has shown. Most of the rest is water. Over the nine years' tracking, the researchers found city trees absorbed four times as much carbon from the air as forest trees. However, they were twice as likely to die. So over the lifetime of each type of tree, forest trees actually absorbed more CO2.City trees grew faster because they had less competition for light from their neighbors. In a forest, trees tend to grow close together, shading their neighbors. Street trees also benefit from higher levels of nitrogen (氮)in rainwater. Nitrogen helps plants grow. Waste gases from gas-burning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground. Some street trees may also have better access to water than trees in the country because the underground water pipes can leak.（1）What can he known about CO2 from paragraph 2?A. It is one of the side effects of greenhouses.B. It greatly accelerates the process of global warming.C. It results from the widespread burning of fossil fuels.D. It prevents the earth from becoming unsuitable to live on.（2）Why did researchers track the diameters of trees?A. To know about their growth rates.B. To find out how much they weigh.C. To check whether they were healthy.D. To assess the carbon amounts in them.（3）What advantage do city trees have over forest trees?A. They are more likely to access growth promoters.B. They can enjoy more water coming from the air.C. They can enjoy more shade from neighbors.D. They are better at competing for light.（4）What will probably be talked about if the passage is continued?A. How urban trees can live longer.B. Why city living makes trees die young.C. How trees respond to dry soil conditions.D. Why faster-growing trees absorb more CO2.【答案】（1）D（2）A（3）A（4）B【解析】【分析】本文是一篇说明文，一项新的研究发现：与长在森林中的树木相比，城市里的树木长得更快，但死得更早。

2022高考英语重庆市阅读理解专项练习（1）及解析AWords：296难度系数：★★建议用时：6分钟With the start of the new semester，students around the country exchange their fun and fashionable clothes for boring school uniforms.“The uniform makes us look like a_bunch_of_clones，especially when we are doing morning exercises in the playground，”said Qing, a Senior 2 from a high school in Shanghai.“But we are not exactly the same from the top to the bottom.The boys wear different sport shoes and girls have different decorations(装饰品) in their hair.These are the areas where you can express yourself，”said Qing.Although it might be strange for boys to talk about fashion，they do care about what they wear in school，especially shoes，according to Qing.“Nike and Adidas basketball shoes，although they are still the must for many of my friends，are becoming out-of-date，”Qing added.He explained, “Since Liu Xiang ran so fast in Athens，running shoes are becoming popular in this Autumn.”“Still in fashion are the various baseball caps and American-style T-shirts with random English words printed on them，”said Qing.“The accuracy (准确性)of the written message isn’t important.Often, the words are misspelt.Sometimes they do not even make sense，” Qing said with a smile.Besides sports shoes and T-shirts, styles and colors of school bags are another opportunity for students to express their taste in fashion.Some bags are made more eye-catching by decorating them with small hanging dolls.Other fashionable items are the colorful drink containers which are now popular among girls this semester.As in China, the new semester in the US also brings new fashion trends: shirts printed with Chinese words, necklaces with Hebrew (希伯莱) or Hindi (印度的) characters, and Brazilian jewelry, are all common in schools in Florida, according to Carmen Domingues, a high school student.1．What does the underlined words“a bunch of clones” in Paragraph 2 mean?A．All of the clothes are the same.B．All of the exercises are the same.C．All of the clothes are different.D．All of the exercises are different.解析：选A。
高考英语：阅读理解专项练习卷(附译文)
高考英语：阅读理解专项练习卷（附译文）（1）Every human being has a unique arrangement of the shin on his fingers and this arrangement is unchangeable.Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.The ridge structure on a person’s fingers does not change with growth and is not affected by surface injuries.Burns,cuts and other damage to the outer part of the skin will be replaced in time by new one,which bears a reproduction of the original pattern.It is only when the inner skin is injured that the arrangement will be destroyed.Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.Finger-prints can be made very easily with printer’s ink.They can by recorded easily.With special methods,identification can be achieved successfully within a short time.Because of the simplicity and economy of this system,finger-prints have often been used as a method of solving criminal case.A suspected man may deny a charge but this may be in vain.His finger-prints can prove who he is even if his appearance has been changed by age or accident.When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye.Special techniques are used to“develop”them.–some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.每一个人在其手指上都有着独一无二的纹路排列，而且这种排列是不会改变的。

高考英语阅读理解抓分精选练习（1）【阅读理解猜想词义】Passage ****************A few years ago it was popular to speak of a penetration gap, a disagreementbetween young people and their elders. Parents said that children did not show themproper respect and obedience, while children complained ( 诉苦 ) that their parentsdid not understand them at all What had gone wrong? Why had the generation gap suddenly appeared? Actually the generation gap has been around for a long time. Many peopleargue that a gap is built into the fabric ( 构造 ) of our society.One important cause of the generation gap is the chance that young people haveto choose their own ways of life. In more traditional societies, when children growup, they are expected to live in the same area as their parents, to marry people thattheir parents know and agree to, and to continue the family occupation ( 职业 ). Inour society, young people often travel great distances for their education, move outof the family home at an early age, marry or live with people whomtheir parents have never met, and choose occupations different from those of their parents.In our easily changing society, parents often expect their children to do betterthan they did; to find better jobs, to make more money; and to do all the things thatthey were unable to do. Often, however, the strong desire that parents have for their children are another cause of the disagreement between them. Often, they discoverthat they have very little in common with each other.Finally, the speed at which changes take place in our society is another causeof the gap between the generations. In a traditional culture, elderly people are valuedfor their wisdom, but in our society the knowledge of a lifetime may become out ofdate overnight. The young and the old seem to live in two very different worlds,separated by different skills and abilities.No doubt, the generation gap will continue to be a feature ( 特色 ) of Americanlife for some time to come It ’s causes are rooted in the freedom and changes ofour society, and in the rapid speed at which society changes.1. The main idea of the first paragraph is that________.A. the generation gap suddenly appearedB. the generation gap is a feature of modern social lifeC. people can reduce the generation gapD. many critics argue over the nature of the generation gap答案： B 指导：本段最后一句。

一、高中英语阅读理解1．阅读理解When Shakespeare was twenty-one, he went to London, a very interesting place, to try his fortune.There was the famous London Bridge and St. Paul's Cathedral, and palaces and markets and long streets full of shops.Then, too, there were the daily crowds where could be seen people from all over the world. Knights, scholars and the highwayman (拦路强盗）or thieves, who had been infamous for their clever robberies, passed by each other.Here, also, were noblemen dressed in gold, from Italy and Spain and France; slaves from Spanish America, sea captains and ministers, soldiers and servants—all held by chances or interests within the gray walls which circled London, and whose gates gave welcome to as strange a crowd as could be found in the world.Into this curious crowd came Shakespeare, quick to see and eager to learn. And before long all these strange sights were as familiar to him as the faces of his own town's residents. Each one told its story to him so plainly that, as before he had learned the secrets of the fields and woods, so now he learned men and men's interests that make up the great world.And he learned these lessons so well that when he came to write his plays, he made such use of them as no writer ever made before or since; for it is the use of this knowledge of the world, combined with his own genius, that makes Shakespeare the greatest dramatist that has ever lived.（1）What was London like in Shakespeare's eyes when he first went there?A. Dirty and small.B. Strange and interesting.C. Infamous and terrible.D. Familiar and modern.（2）Which of the following best describes Shakespeare?A. Shakespeare got inspiration to write from his hometown, London.B. Shakespeare was eager to make friends with the noblemen in London.C. Shakespeare was good at observing and learning from the daily life.D. Shakespeare became the greatest dramatist owing to his own genius.（3）What does the word "one" in paragraph 5 refer to?A. Crowd.B. Resident.C. Face.D. Sight.（4）The passage probably comes from______.A. a posterB. a textbookC. an advertisementD. an announcement【答案】（1）B（2）C（3）D（4）B【解析】【分析】本文是一篇名人轶事，介绍了文学大师莎士比亚年轻时去到伦敦第一天时遇到的有趣的事情。
（1）考查细节理解。
根据第一段中的“a very interesting place”和第五段中的“all thesestrange sights”可知，在 Shakespeare 的眼中，伦敦是一个有趣而陌生的城市。
故选B。
（2）考查推理判断。
根据第五段可知，Shakespeare来到伦敦不久之后，通过观察和学习了解了伦敦，并适应了那里的生活，由此可推断出，Shakespeare擅长观察日常生活并从中学习。
故选C。
（3）考查代词指代。
根据第五段中的“as before he had learned the secrets of the fields and woods”正如他以前所学到的田野和树林的秘密那样，可知，one指的是"像田野和树林一样的景象"。
故选D。
（4）考查推理判断。
本文主要讲述了莎士比亚到伦敦的经历，所以这篇文章最有可能出现在一本教材中。
故选B。
【点评】本题考点涉及细节理解，代词指代和推理判断三个题型的考查，是一篇人物类阅读，考生需要准确捕捉细节信息，并根据上下文的逻辑关系，进行分析，推理，从而选出正确答案。
2．阅读理解NASA has a new job listing, and it's no joke. The US space agency is looking for a "joker" to join their planned mission to Mars.A mission to Mars is no laughing matter. On average, the red planet is 140 million miles (225 million kilometers) away from Earth. A trip there would take around eight months in a small spacecraft. And Mars has a communications delay of 20 minutes. This means that astronauts will have to wait 20 minutes for a reply, when an emergency happens."When you're living with others in a confined space for a long period of time, such as on a mission to Mars, problems are likely to occur," Jeffrey Johnson, a scientist at the University of Florida, told The Guardian.This is probably why NASA wants an astronaut with a sense of humor. "These are people that have the ability to pull everyone together," Johnson said.In stressful situations, perhaps humor is a way to know we aren't alone. By laughing together, we share our stress. Then we can focus on our jobs instead of just worrying.There are other examples of team "clowns". One example is the journey to the South Pole led by Norwegian explorer Roald Amundsen. It was a difficult journey full of danger. Adolf Lindstrom, a cook at Amundsen's team, was a "clown". He made people laugh through the whole journey. Amundsen later wrote that Lindstrom was the most valuable member of the team.But if you're hoping that your favorite TV comedian will fly to Mars, that probably won't happen."Being funny won't be enough to land somebody the job," Johnson said. "They also need to be an excellent engineer."Besides, they must be in top physical condition.（1）What is NASA's new job listing?A. A funny engineer.B. A talented clown.C. A good cook.D. A popular comedian.（2）What does "a confined space" in Paragraph 3 refer to?A. a full spaceB. an empty spaceC. an open spaceD. a small space.（3）How does the author think humor can help astronauts?A. It can stop them from feeling bored.B. It can promote teamwork on a mission.C. It can make them feel less homesick.D. It can help them know themselves better.（4）What's the author's purpose of giving the example of the cook?A. To tell us that what explorers eat on their journey is very important.B. To prove that an amateur can play a more important role than a professional.C. To make the point that humorous people can cheer people up in difficult situations.D. To reveal that a mission to Mars is more difficult than a journey to the South Pole.【答案】（1）A（2）D（3）B（4）C【解析】【分析】本文是一篇说明文，由美国宇航局寻找一位幽默的工程师来和宇航员一起执行航天任务介绍了幽默对宇航员的重要作用。
