高考英语阅读理解专项训练100篇 (名师传授解题技巧+实战练习，值得下载) 一、阅读理解解题技巧 阅读理解题是考查学生对活的语言材料的理解能力，即通过阅读材料获得信息的能力。具体说来，阅读理解能力测试的主要要求是：（1）掌握所读材料的主旨大意，以及用以说明主旨大意的事实和细节；（2）既理解具体事实，也理解抽象的概念；（3）既理解字面意思，也理解深层含义，包括作者的态度、意图等；（4）既理解某句、某段的意义，也理解全篇的逻辑关系，并能根据文章进行推理和判断；（5）既能根据材料所提供的信息去理解，也能结合中学生应有的常识去理解。根据这几项能力测试的要求，试题中常采用如下几种题型：事实询问题、推理判断题、数据推算题、识图解意题和主旨大意题。根据这一测试要求和题型设计，答题时可以采取如下解题技巧和对策。 1．首先解题时要充满自信。由于平时有些同学对做阅读理解时存在一种畏惧心理，因此考试做题时心理就难免会产生紧张感，特别是阅读时再遇到几个生词就头脑发胀，从而使自己的思路更加模糊不清。其实这是完全没有必要的，因为阅读中遇到几个生词或几个难以理解的句子是常有的事，也是正常现象。因为按大纲要求，试卷中允许有不超过3%的生词，只要认真分析，仔细阅读，这些生词和句子很可能并不影响你的解题。所以答题之前首先要有必胜的信心。 2．扫读全文，理解全文主旨大意。拿到一篇文章，首先要快速扫读全文，虽为扫读，但不可漫不经心，阅读时也应聚精会神，力求可能多地获取材料信息，只是这次遇到生词和难句先不必去处理，不要因纠缠文中的个别生词和难句而影响了对全文的主旨大意的了解。
3．对症下药，各个击破。了解全文的大概意思之后，再把短文的问题简单看一遍，弄懂题意，然后带着问题再去寻读全文。这次阅读过程中要善于抓文章中的关键词句。寻读也就是迅速的查找需要了解的信息，是为某些特定的问题而阅读，因此阅读时要有较强的针对性，对与问题有关的数据，词句等仔细阅读，认真理解，同时结合不同考查内容的题型，采取如下解题对策： （1）事实询问题：这类试题通常是以疑问词what，who，when，where，why，how 等引起的特殊问句，就文章中某一词语、某一句子、某一段落或某一具体细节和事实进行提问。解答此类试题首先要弄清题目和每一个选项的含义，然后按题目要求寻找与之相关的细节，正确估计答案来源，同时注意题目和文章中的暗示作用。特别注意辨别各种信息，确认各种信息。 （2）推理判断题：此题要求我们通过表面文字信息去推测文章隐含的意思，对文章的发展情节及作者的态度、意图等做出合乎逻辑的的推理判断。这种题要求我们在阅读时要抓住文章的主题和细节、从分析文章的结构入手，根据上下文的内在联系，充分挖掘文章的深层含义。对暗含在文章中事件的因果关系，人物的动机，以及作者未言明的倾向、态度、意图、观点进行合乎逻辑的推理、分析和判断。同时善于抓住文中实质性的东西，不要被带假象的表面信息或似是而非的东西所迷惑。并且注意推断作者态度时要力求从作者的态度、观点去思考，切勿想当然，凭个人的观点习惯看法来回答的问题。 （3）数据推算题：此题要求我们就文章提供的数据，以及数据与文章中其他信息的关系做出计算和推断，然后做出选择。这就要求我们解题时，要在理解好题意的前提下去对与数据有关的信息认真分析，若数据信息较多，还要注意弄清数据之间的关系，同时分清有用与无用信息，最终作出正确判断。 （4）主旨大意题：此题用以考查我们对文章主题或中心思想的领会和理解能力。在解答此类试题时要注意每段的中心句，抓住每一段的主题句。一般主题句都用来表达一段主旨大意，因此，只要找准每段的主题句，文章的中心思想和文章的最佳标题也就不难确定了。

（英语）高三英语阅读理解解析版汇编 一、高中英语阅读理解 1．阅读理解 In America, parents tend to encourage their children to develop their potential (潜能) to the fullest extent. Fathers and mothers frequently teach their children both ambition and the confidence necessary to work toward their goals. American parents are always active in concentrating on what their kids can do, not what they can't. As a result, millions of American boys and girls grow up hoping to become actors and athletes, diplomats and doctors. Many of them even want to become president. American parents often encourage their children to become involved in extra activities of all types at school, such as student government, sports and music. They believe that only through taking part in these activities can their children become mature young adults. As we all know, school work is important. But parents should realize that the social skills their children learn from natural conversations with each other are as important as schoolwork and the skills they will need in the future work. What's more important in their work is that their children should have a sound knowledge of physics or the ability to communicate effectively. As a rule, Chinese parents don't educate their children about the same kind of ambition and confidence as Americans do, nor do they encourage the same level of participation in extra activities. Children are typically advised to study hard and pass exams. They have to spend a lot of time in doing much schoolwork every day. It is a great waste of time to do so. Now more and more Chinese parents have recognized that they should pay attention to developing the potential of their children. I hope that leaders in Chinese educational circles should take some measures to develop the potential of their children. I am very confident about it. （1）From the passage, we know the American parents pay much more attention to . A. the social skills than Chinese parents B. their children's studying hard and well C. what their children want but they can't D. extra activities than schoolwork （2）According to the passage, Chinese parents . A. know more than American parents to educate their children B. owning ambition and confidence is necessary and important C. pay much more attention to their children's fine future D. don't encourage their children to participate in extra activities （3）From the passage, we can infer . A. American children are brave and adventurous B. American children are more active in their studies C. Chinese children have the ability to communicate effectively D. something should be done to develop the potential of the children in China （4）What's the writer's attitude towards Chinese education reform? A. Neutral. B. Indifferent. C. Positive. D. Negative. 【答案】（1）A
（英语）高三英语阅读理解专项训练及答案 一、高中英语阅读理解 1．阅读理解 The setting was a packed gymnasium just before the start of a game against another school. There were five girls who were members of the Danville High School basketball team—all of them starters. They were not in uniform to play that night and would not be on the team for the rest of this season. They were there to admit their breaking of team rules. They were there to support their coach's decision to take them off the team. They were there to let the town know there was a problem in their little community that needed to be addressed. And they did it with sincere regret rather than defensiveness. While the school had been out for the New Year's holiday, the five girls had gone to the party with several of their friends. There was alcohol there. And they all drank some. Coach Rainville has a zero tolerance rule on drugs and alcohol for her members though it was a hard decision to make. When classes resumed and accounts of holiday parties were shared, rumors about the five girls began closing in on them. The coach said she couldn't back down on her rules. And the players—two junior students and three senior students—agreed. That night in the gym was part of their public support of the coach's decision. “We hope you will understand that we are not bad kids. What we did was definitely not worth it. We hope this event will make everyone realize that there is a big drug and alcohol problem in our community,” one of the senior students said, “And if you work with us to try to solve this problem, you will help us feel that we have not been thrown off our basketball team for nothing.” The five left the floor to deafening applause. The team may not win another game this year. But they've learnt something about personal responsibility, the effect of one's action on others, and honesty that will serve them well throughout life. （1）It can be inferred from the passage that the five girls who were kicked off the team were ________. A. very good players on the team B. addicted to alcohol and drugs C. three junior students and two senior students D. scolded by their parents for drinking alcohol （2）What did the girls do to support their coach's decision? A. They didn't fight for Danville High School any more. B. They all gave speeches to apologize in the local press. C. They admitted their mistake in public in the gymnasium. D. They would never drink any alcohol throughout their life. （3）Which word best describes the coach Rainville? A. Indifferent. B. Strict. C. Stubborn. D. Cruel. （4）Which would be the best title for the passage? A. Growing up with pain B. A bad mistake C. Team rules are everything D. Basketball girls in high school 【答案】（1）A

I watched from a distance as the homeless man quarreled with those who did not leave money for him – the majority. I walked up to him and right on queue he asked me for a quarter. ―I’ll give you a quarter if you tell me your story.‖ He laughed, ―You’ll give me a quarter for my story?‖ I lay the quarter in front of him and corrected myself –―Nah, here’s the quarter but it would be nice to hear your story.‖ I followed his eyes to the quarter and for a brief moment I saw a glimmer of reflection. I sat down next to him and waited. ―I was in the army,‖ he said. ―I was a sniper(狙击手)and was supposed to shoot down the enemy from the distance.‖ I listened carefully to his grizzly voice as he went deeper into the story. He wore dirty old torn clothes and smelled like a dead rat left in a mouse trap. He told me how he used to hunt with his family and was really good at it. He had his own way of respecting animals by not wasting what he killed for food and not killing more than he needed. When the army came knocking on his door, he felt pride and joined up. All those years of polishing his hunting skills could now serve a larger purpose—to defend us from the bad guys. He set out to fight in Iraq. It wasn’t long before he realized his ideals and expectations were just a shadow of the truth. He became disillusioned with the killings, which he felt were of innocent people. ―I was a sniper but I never really killed anyone,‖ he said. ―One day I had to do it. They asked me to shoot this lady from the distance. I saw kids near that lady and my hands were on the trigger (扳机). Man, I was tearing up ... I couldn’t do it. She wasn’t doing anything to anyone and she was with the kids—I couldn’t see through my tears. It just didn’t make any sense to me.‖ The story goes on as he describes eventually being put into prison for 180 days for refusing to follow orders. He told me how he was black listed so that he couldn’t get a job. All the rights we take for granted were taken away from him. Why? Here was a man who was being punished—and for what? For refusing to kill the lady? For being a hero? ―I have no regrets,‖ the homeless man said. ―I may be homeless now, but I never killed that lady. I never killed anyone in the army. It didn’t feel right. I didn’t go there to do that. I went there to save people.‖ He continued, ―I can live with being homeless—that’s okay. But I wouldn’t be able to live with killing innocent people.‖ On that lonely Friday night, I met a hero. It just never occurred to me that a hero could be a smelly old man left on streets. 1. It can be learned from the passage that the homeless man_______. （） A. never killed animals B. had a strong respect for life C. deserved the punishment he received D. felt guilty about disobeying the order
高考英语阅读理解专项训练及答案及解析 一、高中英语阅读理解 1．阅读理解 Traditional Chinese medicine (TCM) is gaining global popularity. According to a government white paper, TCM has been introduced in 183 countries and regions around the world. Westerners' understanding of TCM, however, may be limited to acupuncture, cupping and massage(针灸，拔罐和按摩). For instance, the purple, injury-like marks left on U. S. swimmer Michael Phelps，back from cupping for the purpose of relaxing his muscles and reducing pain became the center of attention during the Rio Olympics in 2016. As a matter of fact, Chinese herbs play a more important role in getting rid of diseases and keeping the body in good condition in the TCM treatment system than physical treatment. It is therefore disheartening to know that while 103 World Health Organization member countries have given approval to the practice of acupuncture, not many recognize Chinese herbal medicine. TCM falls far behind Western medicine owing partly to the slow development of Chinese herbs. Herbs are made into pills, powder and soup, and the kind of herbs used, their quality and quantity, and the processing of the ingredients (原材料) jointly determine the effectiveness of the prescription. Compared with Western medicine, which has standardized drug production processes and treatment methods, TCM lacks standardization, with the chemical composition and functions of its medicines being unclear and their effects being unstable. Fortunately, standardization has improved in recent decades, with an increasing number of factories producing patented TCM drugs. Another factor that has prevented the development of TCM prescription drugs is the lack of creativity. While Western medicine-making companies come up with new products every year, TCM drug producers tend to make medicines according to prescriptions handed down from the past. Chinese chemist Tu Youyou's winning the 2015 Nobel Prize in Physiology or Medicine for her research into malaria (疟疾) treatment may drive creativity to some extent in China's TCM industry. However, the current state of affairs cannot be changed within a short time. （1）Why does the author mention the example of Michael Phelps? A. Because he was injured in his swimming. B. Because cupping is a kind of important TCM treatment. C. Because westerners know a little about TCM. D. Because westerners attach great importance to TCM. （2）Why don't some member countries of WHO recognize Chinese herbal medicine? A. Because Chinese herbs can get rid of diseases. B. Because they only approve the practice of acupuncture. C. Because Western medicine is more effective. D. Because medicine made out of Chinese herbs develops slowly. （3）Compared with Western medicine, what is the weak point of TCM in Paragraph 4? A. The methods of planting herbs. B. The effectiveness of prescription. C. Lacking in standardization. D. Its stable functions.

【英语】高考英语阅读理解专项练习及解析 一、高中英语阅读理解 1．阅读理解 Money is the root of all evil (邪恶) and new study claims there may be some truth behind the saying. Scientists at the University of California Berkeley, US, announced on February 27 that rich people are more likely to do immoral things, such as lie or cheat, than poorer people. The scientists did a series of eight experiments. They published their findings online in the Proceedings of the National Academy of Sciences (PNA《美国国家科学院院刊》). They carried out the first two experiments from the sidewalk near Berkeley. They noted that drivers of newer and more expensive cars were more likely to cut off other cars and pedestrians at crosswalks. Nearly 45 percent of people driving expensive ears ignored a pedestrian compared with only 30 percent of people driving mow modest cars. In another experiment, a group of college students was asked if they would do immoral things in various everyday situations. Examples included taking printer paper from work and not telling a salesperson when he or she gave back more change. Students from higher — class families were more likely to act dishonestly. According to the scientists, rich people often think money can get them out of trouble. This makes them less afraid to take risks. It also means they care less about other people's feelings. Finally, it just makes them greedier. “Higher wealth status seems to make you want even more, and that increased want leads you to bend the rules or break the rules to serve your self- intere st,” said Paul Piff, lead scientist of the study. Piff pointed out that the findings don't mean that all rich people are untrustworthy or all poor people honest. He said the experiments were to show how people living in different social situations express their instincts（本能）and values in different ways. （1）By saying “money is the root of all evil”, the author wants to . A. link wealth with bad behavior B. draw readers' attention to the research C. show how the saying proves the findings D. defend rich people who do immoral things （2）According to the scientists, which is NOT the factor that makes rich people immoral? A. They welcome risks. B. They have more desires. C. They believe money talks. D. They become more selfish. （3）Why did the scientists do the experiments? A. To show how social status affects people's morality. B. To show people's instincts and values in different ways. C. To test whether the saying “money is the root of all evil” is true. D. To show the difference between higher - class people and lower - class people. （4）What does the passage really want to show us? A. The poor are respectable. B. Money is the root of all evil. C. All rich people are untrustworthy. D. The rich are more likely to act badly. 【答案】（1）B （2）A
