1、高考英语二轮复习艺体生专练专题19 阅读理解说明文类专题19 阅读理解说明文类方法与技巧题型介绍：材料特点这类文章的总体特点是：科技词汇多，句子结构复杂，理论性强，逻辑严谨。具体说来它有以下几个特点：1. 文章中词汇的意义比较单一、稳定、简明，不带感情色彩，具有单一性和准确性的特点。这类文章通常不会出现文学英语中采用的排比、比喻、夸张等修辞手法，一词多义的现象也不多见。2. 句子结构较复杂，语法分析较困难。为了描述一个客观事物，严密地表达自己的思想，作者经常会使用集多种语法现象于一体的长句。3. 常使用被动语态，尤其是一些惯用被动句式。命题形式：命题特点科普类阅读的主要命题形式有事实细节题、词

2、义猜测题、推理判断题以及主旨概括题等，其中推理判断题居多。方法概述高考对说明文的考查多为科普说明文，它是阅读理解重要内容，也是高考考查难点。科普类“阅读理解”题愈来愈受到命题者的青睐而科普类文章往往具有跨学科行文逻辑性强等特点,要求考生能从文章的整体逻辑以及重要细节上全面把握【试题特点】 注重学科渗透,行文逻辑性强,内容抽象 贴近学生的学习生活实际,有利于激发学生的思维,对选拔优秀考生有一定的作用 能全面地考查学生的综合阅读能力和运用所学知识去分析解决实际问题的能力 (4)科学方法图示判断题 科普说明文常出现科学方法图示判断题，这种试题或以生物依赖关系为命题题点，要求考生判断正确的生物依赖关系

3、；或以工艺流程为命题题点，要求考生判断正确的流程顺序，或以生产方法为命题题点，要求考生判断正确的生产方法；或以机械配制为命题题点，要求考生判断正确的机械配制。解题时一定要认真阅读分析原文对生物依赖关系、发明创造诞生过程和工艺流程过程的介绍，并且边读边画简易草图，以提高理解准确率。分析备选项时应对照原文介绍情况，找出各图不同之处，以便最终做出正确判断。命题方式考点一、细节事实理解。一篇文章必然是由许多具体的细节、具体的内容构成的，所有这些信息以某种顺序（时间、空间、情感变化等）排列起来，来进一步解释或阐释主题，体现文章的主旨大意。 细节理解题目主要考查学生对文章具体事实和细节的理解能力，属于表层

4、理解题范畴，难度较小，但在整个阅读理解题中所占比例最大，细节理解题多从文章的某个具体事实或细节出发来设计题目。此类题通常根据文章具体内容来设问，也常使用下列方式来提问 1.Which of the following statements is(not) true/correct? 2.Which of the following is not mentioned? 3.All of the following are true except. 4.According to the passage,when/where/why/how/how/what/which,etc.？1.直接事实题 在

5、解答这类问题时要求学生抓住题干文字信息，采用针对性方法进行阅读，因为这类题的答案在文章中可以直接找到。 如：A giant dam was built many years ago to control the Colorado River in the U.S.This dam was built to protect the land and houses around the river.This huge dam is in the Black Canyon.It is possible to drive a car from one side of the river to the

6、other on a road，which is on the top of the dam.This dam is so big that there is an elevator inside.The elevator goes down forty-four stories from the road to the bottom.There is enough concrete in this dam to build a highway from New York to San Francisco.Thousands of people worked on this dam for f

7、ive years.This huge dam was called Boulder Dam when it was finished in 1936.Later it was renamed Hoover Dam in honor of a president of the United States.Hoover Dam，one of the highest dams in the world，is situated between the states of Arizona and Nevada.Q：Hoover Dam lies_ .A.between Arizona and Neva

8、daB.in the Black CanyonC.between New York and San FranciscoD.both A and B【解析】由第二段的第一句话和最后一段的最后一句话可得出正确答案是D项。2.间接事实题 解答此类题，需要结合上下文提供的语境和信息进行简单的概括和判断或者要进行简单的计算。Invited by Mr.Ye Huixian，host of the well-received TV programme“Stars Tonight”，Miss Luo Lin，Miss Asia of 1991，appeared as the guest hostess on

9、 the Shanghai TV screen last Sunday.Born in Shanghai and taken to Hongkong when she was only six years old，Luo Lin has never dreamed of being Miss Asia.Her childhood dream was to be an air hostess.Before she took part in the competition，she had been an airhostess in Cathay Airline for seven years.Ho

10、wever， it still took her three months to learn the art of walking on the stage，dancing,singing,making-up and other proper manners，designed by the Asia TV Station.“Its really a hard job for me.I wont enter for such competition any more.Anyhow，I am quite lucky.I am also glad to have had more chance to

11、 work for the social welfare since I won the title.This time，in Shanghai，Id love to make a deep impression on my TV audience，”said Luo Lin with a sweet smile.Q：Which of the following is NOT true?A.Luo Lin is a native of Shanghai.B.Luo Lin moved to Hongkong with her parents.C.Luo Lin won the title of

12、 Miss Asia in 1991.D.Asia TV Station helped Luo Lin to become Miss Asia.【解析】A、C和D项都可在原文找到答案，而B项原文所给的是：taken to Hongkong可判断不是moved to Hongkong with her parents，因此选B。 3、数据推算。If you register both the VIEW qualification course and the Forum at the same time,you will save_ .A.$100 B.$300 C.$350 D.$400 这类

13、题目要求学生就文章提供的数据，以及数据与文中其他信息的关系做简单计算和推断。在做此类题时：1.要抓住并正确理解与数据有关的信息含义。2.弄清众多信息中那些属于有用信息，那些属于干扰信息。3.不要孤立看待数字信息，而要抓住一些关键用语的意义。考点二、主题理解或写作意图推断。一、主旨阅读理解题考查的内容 1.短文的标题（title,headline）； 2.短文或段落的主题（subject）； 3.中心思想(main idea)； 4.作者的写作目的(purpose)。 二、此类题的设问方式 1.What would be the best title for the text? 2.What d

14、oes the second paragraph mainly discuss? 3.What is the passage mainly about? 4.The main purpose of announcing the above events is_. 考点三、推理推断。推理题要求考生根据文章提供的事实和线索进行逻辑推理，推断出作者没有提到或者没有明说的事实或者可能发生的事实。这类题旨在考查学生透过词语的字面意义去理解作者的言外之意或弦外之音的能力，属于深层理解题。 此类题的设问常常包括infer,imply,suggest,conclude 等词，这类题的设问方式主要有： 1.We

15、 can infer from the Passage that_. 2.What can be inferred from the Passage? 3.Which of the following can be inferred from the Passage? 4.It can be inferred from Paragraph 3 that_. 5.The author suggests in this paragraph that_. 6.The writer implies that_. 7.It can be inferred that_. 8.It can be concl

16、uded from the Passage that_. 9.On the whole,we can conclude that_. 10.From the text we can conclude that_. 11.After reading the Passage we may conclude that_. 12.What conclusion can be drawn from the Passage? 13.The author is inclined to think that_. 14.When the writer talks about,what he really mea

17、ns is that_. 15.Whats the writers attitude/feeling towards.? 16.In the writers opinion,. 考点四、词义、句义猜测。词义猜测阅读理解题考查对文中关键词语的理解。在阅读理解题中，所考查的词或短语的意义往往不停留在字面上，要根据语境来判断。 此类题的设问方式主要有 1.The word “.”in Line.means/can be replaced by. 2.As used in the passage,the phrase “.”suggests. 3.From the passage,we can inf

18、er that the word/phrase “.” is/referred to. 4.The word “.” is closest in meaning to.猜词是应用英语的重要能力，也是高考中常用的题型。它不但需要准确无误地理解上下文，而且要有较大的泛读量，掌握或认识较多的课外词汇。我们要学会“顺藤摸瓜”，通过构词、语法、定义、同位、对比、因果、常识、上下文等线索确定词义。1.定义法。如:Annealing is a way of making metal softer by heating it and then letting it cool very slowly.句子给予a

19、nnealing 以明确的定义，即 “退火”。It will be very hard but also very brittlethat is,it will break easily.从后面的解释中我们可以了解到brittle 是“脆”的意思。The herdsman,who looks after sheep，earns about 650 yuan a year.定语从句中 looks after sheep 就表明了 herdsman 的词义为“牧人”。2.同位法。如:They traveled a long way and at last got to a castle,a lar

20、ge building in old times.同位语部分a large building in old times 给出了 castle 的确切词义，即“城堡”。We are on the night shiftfrom midnight to 8 a.m.this week.两个破折号之间的短语很清楚地表明night shift 是“夜班”的意思。3.对比法。如:She is usually prompt for all her class,but today she arrived in the middle of her first class.but一词表转折，因此but 前后的意

21、思正相反。后半句的意思是“她今天第一节上了一半才来”，因此反向推理，可得出她平时一向“准时”的结论。4.构词法(前缀、后缀、复合、派生等)。如:Perhaps,we can see some possibilities for next fifty years.But the next hundred?possibility 是 possible 的同根名词,据此可以判断定 possibility 意思是“可能性”。5.因果法。如：The lack of movement caused the muscles to weaken.Sometimes the weakness was perma

22、nent.So the player could never play the sport again.从后面的结果“永远不能再运动”中，可以推测 permanent 的意思为“永远的，永久”。体验高考2017北京卷DHollywoods theory that machines with evil(邪恶的) minds will drive armies of killer robots is just silly. The real problem relates to the possibility that artificial intelligence(AI) may become

23、extremely good at achieving something other than what we really want. In 1960 a wellknown mathematician Norbert Wiener, who founded the field of cybernetics(控制论), put it this way: “If we use, to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere(干预), we ha

24、d better be quite sure that the purpose put into the machine is the purpose which we really desire.”A machine with a specific purpose has another quality, one that we usually associate with living things: a wish to preserve its own existence. For the machine, this quality is not inborn, nor is it so

25、mething introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead. So if we send out a robot with the single instruction of fetching coffee, it will have a strong desire to secure success by disabling its own off switch or

26、 even killing anyone who might interfere with its task. If we are not careful, then, we could face a kind of global chess match against very determined, super intelligent machines whose objectives conflict with our own, with the real world as the chessboard. The possibility of entering into and losi

27、ng such a match should concentrate the minds of computer scientists. Some researchers argue that we can seal the machines inside a kind of firewall, using them to answer difficult questions but never allowing them to affect the real world. Unfortunately, that plan seems unlikely to work: we have yet

28、 to invent a firewall that is secure against ordinary humans, let alone super intelligent machines.Solving the safety problem well enough to move forward in AI seems to be possible but not easy. There are probably decades in which to plan for the arrival of super intelligent machines. But the proble

29、m should not be dismissed out of hand, as it has been by some AI researchers. Some argue that humans and machines can coexist as long as they work in teamsyet that is not possible unless machines share the goals of humans. Others say we can just “switch them off” as if super intelligent machines are

30、 too stupid to think of that possibility. Still others think that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, with confidence, “Anyone who expects a source of power in the transformation of these atoms is talking moonshine.” However, on S

31、eptember 12, 1933, physicist Leo Szilard invented the neutroninduced(中子诱导) nuclear chain reaction.67Paragraph 1 mainly tells us that artificial intelligence may _Arun out of human controlBsatisfy humans real desiresCcommand armies of killer robotsDwork faster than a mathematician68Machines with specific purposes are associated with living things partly because they might be able to _Aprevent themselves from being destroyedBachieve their original goals independentlyCdo anything successfully with given ordersDbeat humans in
