(英语)英语阅读理解练习题20篇及解析一、高中英语阅读理解1.阅读理解Many people have long dreamed of being able to fly around as simply as riding a bicycle. Yet the safety and strength of a flying bike was always a big problem. Over the past 10 years, developments in technology have moved the dream of personal flying vehicles closer to reality. Now, two groups of inventors say such vehicles may be available soon.The British company Malloy Aeronautics has developed a prototype (原型) of its flying bicycle. Grant Stapleton, marketing sales director of Malloy Aeronautics, says the Hoverbike is able to get in and out of small spaces very quickly. It can be moved across continents very quickly because it can be folded and packed, he adds.Mr. Stapleton says safety was the company's main concern. He says the designers solved the safety issue by using overlapping rotors ( 交叠式旋翼 )to power the vehicle.The company is testing a full-size prototype of the Hoverbike, which will most likely be used first by the police and emergency rescue teams.In New Zealand, the Martin Aircraft Company is also testing a full-size prototype of its personal flying device, called the Jetpack. It can fly for more than 30 minutes, up to 1,000 meters high and reach a speed of 74 kilometers per hour.Peter Coker is the CEO of Martin Aircraft Company. He said the Jetpack “is built around safety from the start. In his words, reliability is the most important element of it. We have safety built into the actual structure itself, very similar to a Formula One racing car.”The Jetpack uses a gasoline-powered engine that produces two powerful jet streams. Mr. Coker says it also has a parachute (降落伞) that can be used should there be an emergency. “It starts to work at very low altitude and actually saves both the aircraft and the pilot,” he adds. Mr. Coker says the Jetpack will be ready for sale soon.(1)We can learn from the passage that the Hoverbike .A. can hardly get in and out of small spaces quicklyB. can fly for over 30 minutes, up to 1,000 meters highC. has been used by the police and emergency rescue teamsD. can be transported quickly after being folded and packed(2)The writer uses the example of For One racing car to show that .A. the Jetpack is very safe and reliableB. the engine of the Jetpack is powerfulC. the actual structure of the Jetpack is uniqueD. the Jetpack can reach a great speed and height(3)The underlined word “it” in the last paragraph refer s to.A. the jet streamB. the engineC. the JetpackD. the parachute (4)What is the authors main purpose of writing the passage?A. To describe the problems of inventing flying vehicles.B. To introduce the latest development of flying vehicles.C. To show the differences between two flying vehicles.D. To advertise the two personalflying vehicles.【答案】(1)D(2)A(3)D(4)A【解析】【分析】本文为说明文,主要讲述一种个人飞行工具很快就会应用于现实。
(英语)英语阅读理解练习题20篇含解析一、高中英语阅读理解1.阅读理解Science is finally beginning to embrace animals who were, for a long time, considered second-class citizens.As Annie Potts of Canterbury University has noted, chickens distinguish among one hundred chicken faces and recognize familiar individuals even after months of separation. When given problems to solve, they reason: hens trained to pick colored buttons sometimes choose to give up an immediate food reward for a slightly later (and better) one. Healthy hens may aid friends, and mourn when those friend die.Pigs respond meaningful to human symbols. When a research team led by Candace Croney at Penn State University carried wooden blocks marked with X and O symbols around pigs, only the O carriers offered food to the animals. The pigs soon ignored the X carriers in favor of the O's. Then the team switched from real-life objects to T-shirts printed with X or O symbols. Still, the pigs walked only toward the O-shirted people: they had transferred their knowledge to a two-dimensional format, a not inconsiderable feat of reasoning.I've been guilty of prejudiced expectations, myself. At the start of my career almost four decades ago, I was firmly convinced that monkeys and apes out-think and out-feel other animals. They're other primates(灵长目动物), after all, animals from our own mammalian(灵长目动物) class. Fairly soon, I came to see that along with our closest living relatives, whales too are masters of cultural learning, and elephants express profound joy and mourning with their social companions. Long-term studies in the wild on these mammals helped to fuel a viewpoint shift in our society: the public no longer so easily accepts monkeys made to undergo painful procedure in laboratories, elephants forced to perform in circuses, and dolphins kept in small tanks at theme parks.Over time, though, as I began to broaden out even further and explore the inner lives of fish, chickens, pigs, goats, and cows, 1 started to wonder: Will the new science of "food animals" bring an ethical (伦理的) revolution in terms of who we eat? In other words, will our ethics start to catch up with the development of our science?Animal activists are already there, of course, committed to not eating these animals. But what about the rest of us? Can paying attention to the thinking and feeling of these animals lead us to make changes in who we eat?(1)According to Annie Potts, hens have the ability of .A. interactionB. analysisC. creationD. abstraction(2)The research into pigs shows that pigs .A. learn letters quicklyB. have a good eyesightC. can build up a good relationshipD. can apply knowledge to new situations(3)Paragraph 4 is mainly about .A. the similarities between mammals and humansB. the necessity of long-term studies on mammalsC. a change in people's attitudes towards animalsD. a discovery of how animals expressthemselves(4)What might be the best title for the passage?A. The Inner Lives of Food AnimalsB. The Lifestyles of Food AnimalsC. Science Reports on Food AnimalsD. A Revolution in Food Animals【答案】(1)B(2)D(3)C(4)A【解析】【分析】本文是一篇议论文,论述了动物也有情感有思想,有一定的分析推理能力。

AAccording to a new survey, students’ safety has become a big problem. Nearly 50% of students say they are worried about robbery on the way to and from school. Now in main big cities in China, some schools have taught an unusual lesson: self-protection. Students like this lesson because there are no exams or boring classes.

Few students like homework, but it is an important part of middle school life in the UK.The UK has these rules for homework: Grades7and 8 ( ages 11 to 13 ): 45 to 90 minutes per day; Grade 9 ( ages 14 to 15) :1 to 2 hours a day.Today, many homework tasks are done on a computer. For example, preparing reports, usingthe Internet or doing online tasks. So schools are usually open before and after normal hours. Inthis way, students without computers or the Internet at home can use the schools' facilities (设备) .Sometimes, students are given extended learning tasks. That means they need to do more research and analysis(分析) .But however big a task is, teachers always give feedback 反馈) to help students find the areas where they can improve.Some schools send students home with home diaries. They advise parents to check on their Children's progress. Sadly, not every parent takes much interest. In a survey of 1,000 students aged 11 to 18, over 10 percent said that they did not have space at home to do homework. Almost 15 percent said their families did not support them enough.(1) In the UK, which one of the following shouldn't do homework for more than 90 minutes?A. A student of 12.B. A girl of 14.C.

【英语】英语阅读理解练习题20篇一、高中英语阅读理解1.阅读理解They had a dozen children, six boys and six girls, in seventeen years. One reason Dad had so many children was that he was confident anything he and Mother teamed upon was sure to be a success.Our house at Montclair, New Jersey, was a sort of school for scientific management and the removal of wasted motions —or “motion study,” as Dad and Mother named it.Dad took moving pictures of us children washing dishes, so that he could determine how we could reduce our motions and thus hurry through the task. Each child who wanted extra pocket money put forward an offer saying what he would do the job for. The lowest bidder got the contract(合约).Dad put process and work charts in the bathrooms. Every child old enough to write — and Dad expected his children to start writing at a young age — was required to sign their names on the charts in the morning after he had brushed his teeth, taken a bath, combed his hair, and made his bed. At night, each child had to weigh himself, mark the figure on a graph, and sign the process charts again after he had done his homework, washed his hands and face, and brushed his teeth. Mother wanted to have a place on the charts for saying prayers, but Dad said as far as he was concerned prayers were voluntary.It was strict management, all right. Yes, at home or on the job, Dad was always the efficiency expert. He buttoned his vest from the bottom up, instead of from the top down, because the bottom-to-top process took him only three seconds, while the top-to-bottom took seven. He even used two shaving brushes to make his face smooth enough, because he found that by so doing he could cut seventeen seconds off his shaving time. For a while he tried shaving with two razors, but he finally gave that up.“I can save forty-four seconds,” he complained, “but I wasted two minutes this morning putting this bandage on my throat.” It wasn't the injured throat that really bothered him. It was the two minutes.(1)Why was the author's house considered a sort of school?A. It had a team of twelve children there.B. The children were taught how to work well in it.C. The parents could teach their children better at home.D. The parents could have the children's daily activities recorded.(2)What is the purpose of signing the charts?A. To help to do things efficiently.B. To manage the big family effectively.C. To look after the children better.D. To remind the children to obey the rules.(3)What did the father complain about one morning?A. He should have given up shaving.B. His bleeding throat bothered him.C. He couldn't shave with two razors.D. He failed to cut short his shaving time.(4)We can we infer from the text?A. The kids had to bid for everything they wanted.B. The author took pride in his father's management.C. The couple were always troubled by their children.D. The father's work was to teach the children at home.【答案】(1)B(2)A(3)D(4)B【解析】【分析】本文是一篇记叙文,作者父亲有一套严格有效的管理教育子女的方法,使作者感到自豪。

英语阅读练习题(1)Matt Scott, who was born with spina bifida (脊柱裂), grew up in Detroit, Michigan, where he participated in a variety of sports alongside his healthy friends. Now a member of University of Wisconsin-Whitewater wheelchair basketball team, Scott has won four national champion-ships, and has recently been selected to the Paralympic (残奥会) team for the second time. The 23-year-old college senior owes his achievements to his hard work and the support of his friends and family, who never allowed him to use his disability as an excuse. "My mother was always great. Whenever I felt like giving up, she had no sympathy. She really helped me build my independence by not babying me the way other mothers would have," Scott says.It was Scott’s independent nature and strong will, along with his on-the-court skills, that attracted the attention of America’s most influential sports apparel (衣服) company, Nike. Nike was searching for an athlete with a disability to represent its "Just Do It" trademark. A handful of superstar athletes with disabilities came to audition for the role, but the company picked Scott to star in the 30-second commercial."I think that they were looking for the prettiest face in America, and found me," Scott jokes about the selection process.After being picked, Scott flew to California to film the commercial with Oscar-winning documentary director Errol Morris. The ad gave Scott celebrity (名人) status in the community of disabled athletes. He’s been asked to speak at a number of disability-related events, and feels it’s his duty to use the media to draw attention to those with disabilities." I’ve been given a voice, and I want to do whatever I can to break down the social barriers (障碍)that are still faced by disabled athletes, and make people realize that they have a very high athletic level," Scott says.When Scott was young, _________.A. he only played basketball with other disabled childrenB. he became disabled during a basketball matchC. his friends looked down upon him during basketball matchesD. his mother didn’t give him special treatmentNike chose Scott to star in its commercial for his _________.a. pretty appearanceb. independent naturec. strong willd. excellent basketball skillse. status in the community of disabled athletesA. bceB. AdeC. abdD. bcdThe underlined phrase "audition for" in the second paragraph means "________".A. try out forB. pick outC. take onD. look out forWhich of the following about Scott is TRUE?A. He has graduated from the University of Wisconsin-Whitewater.B. He thinks it’s unwise for the disabled to use disability as an excuse.C. He starred in a commercial together with Errol Morris.D. He thinks it’s important to have many goals.(2)The Darwin Myth: The Life and Lies of Charles Darwin Writer: Benjamin WikerList Price: $27.95 Price: $18.45 as a club member or when your orders are over $50 You Save: $9.50 (34%) Product DescriptionIn the 150 years since the publication of Origin of Species, Charles Darwin has been considered between two extremes (极端) —a great biologist or heretic (持异端学说者). However, the truth is much more difficult to understand than that. In any case, Darwin’s theory of evolution and natural selection had the greatest influence in history.In The Darwin Myth, author Benjamin Wiker offers a full-side analysis of Darwin’s theories as well as the social, scientific, and religious effect of his work. Scientists often attack traditional theory and cause debates that will last for generations. Still no scientist has fuelled more debates than Charles Darwin. To some he is the revolutionary "father" of evolution. To others his theory of evolution unconsciously contradicts many ideas in modern eugenics (优生学) in many ways. In The Darwin Myth: The Life and Lies of Charles Darwin, author Benjamin Wiker will make them clear. ContentsSo who is Charles Darwin? What did he really believe and what did his research really prove? In this book, Benjamin Wiker cuts through the myths and sets the record straight. In The Darwin Myth, Wiker tells us: * How Darwin set out to create a godless theory of evolution;* Why many of his best friends criticized Darwin’s theory, and why he never defended himself;* Why Darwin’s theory in a certain way supported slavery, an institution(制度)he hated;* How much of what we know about Darwin comes from his Autobiography, in which the key points are completely misleading.If you buy two copies of The Darwin My that a time, how much should you pay?A. $55.90.B. $36.90.C. $50.D. $27.95.According to the text, what is The Darwin Myth mainly about?A. An analysis of Darwin’s theories and debates about him.B. A brief introduction to Darwin’s life.C. How Darwin created theory of evolution.D. Why many people criticized Darwin’s theory o f evolution.From the text, we know that ________.A. The Darwin Myth is Darwin’s autobiographyB. Origin of Species was published 150 years agoC. Darwin’s theory agrees with modern eugenicsD. Darwin supported slaveryWe can infer from the text that _________.A. Darwin lost many of his best friends because of his theoryB. Darwin’s Autobiography has misled many readersC. Benjamin Wiker is one of Darwin’s friends who knew him wellD. The Darwin Myth will remove the debates about Darwin(3)More than six million students attend California public schools, and the state approves new textbooks in six-year cycles. But now California has a new program called the Digital Textbook Project, and it has become the first state in the United States to provide schools with digital textbooks.Recently Governor Arnold listed reasons why digital textbooks make sense. They can contain the latest information, and make schoolbags lighter. They save paper and trees, and make learning more interesting. Finally, they can help schools with their finances. The state has had to make severe cuts in school spending because of its financial problems.Earlier this year, California invited content developers to offer digital math and science materials for high schools. These had to meet at least 90 percent of the state’s learning requirements. Specially trained teachers examined sixteen textbooks and approved ten of them. Six of the ten were published by the CK12 Foundation, which had been developing digital science and math books for about two years. The foundation paid teachers and other workers to write and edit textbooks, with the money coming from a group financed by the Khosla family.However, California cannot require schools to use the digital textbooks. The schools have the right to decide for themselves, and so immediate widespread use of them is not expected. Susan Martimo, a California Department of Education official, says that schools that already incorporate a lot of technology will be the first to use them, but only in addition to their traditional textbooks.School administrators (管理人员) point out that the texts may be free online, but students need a way to access them. Right now not every student has a computer. Schools could print out copies, but that would be defeating much of the purpose of having them in the first place.What is the text mainly about?A. Differences between traditional textbooks and digital ones.B. A project to encourage the use of digital textbooks in California.C. How to create digital textbooks.D. The popularity of digital textbooks.Which of the following is NOT the advantage of digital textbooks?A. They contain the latest information.B. They help decrease school costs.C. They make learning more appealing.D. They cost nothing to be made.According to the text, six of the ten digital textbooks are published by _______.A. the content developersB. the Khosla familyC. the CK12 FoundationD. the school administrators(4)Scrub jays (灌丛鸦) can trick you, researchers say. Monkeys kick themselves for mistakes in judgment. And at least one parrot has figured out something close to the mathematical concept of numbers.Animals can be remarkably devoted. What’s less obvious is how smart they are. In the studies over the past decades, they’ve shown abilit ies previously thought to exist only in humans.A few years ago, Cambridge University professor Nicky Clayton found that scrub jays can be surprisingly smart, remembering not only what foods they’ve hidden but where,how long ago, and whether anyone else might have noticed. "If another bird was watching, they’d wait until that bird was gone and then move the food," Clayton says.Even more interesting is that not all jays protect their food that way —only those that have previously stolen food from other birds. "It takes a thief to know a thief," says Clayton. Another recent experiment suggests that monkeys experience regret when they make bad choices and miss out on treats. Researchers say brain scans suggest the animals have "could have, would have, should have" thoughts in such situations."I knew monkeys were smart, but I didn’t think they were that smart," says Dr. Michael Platt, the Duke University neurobiologist who led the study.But perhaps no animal turned out to be smarter than Alex, an African gray parrot. In a 30-year research carried out by scientist Irene Pepperberg, Alex showed that parrots were not mere mimics. One afternoon, he even seemed to grasp something only humans and a few apes (猿) had been known to understand: the concept of numbers.Pepperberg had a plate of differently colored balls, and wanted Alex to count each group. She asked, "What color six? What color two?" Bored, Alex threw the balls onto the floor instead. Finally Pepperberg asked, "What color five?" There were no five of anything on the plate, and Alex said, "None."The sentence "It takes a thief to know a thief" in the text shows that ___________.A. scrub jays can remember where their food isB. scrub jays like playing tricks on peopleC. not all jays protect their food as if others were thievesD. scrub jays like to move their food by themselvesPepperberg’s experiment in the last paragraph shows that __________.A. parrots like to imitate humansB. Alex has the concept of numbersC. humans and monkeys understand "zero"D. animals have the concept of colorWhich of the following statements is TRUE?A. People used to think only humans had some thinking abilities.B. Clayton led the recent experiment involving mon-keys.C. Alex is smarter than other parrots.D. Platt has studied parrots for 30 years.。
