3、体事实和细节的理解能力，属于表层理解题范畴，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，也常使用以下方式来提问 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/whi

4、ch,etc.？1.直接事实题 在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

5、the river to the 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

6、on this dam for five 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

7、 Arizona and NevadaB.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

8、 guest hostess on 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 f

9、or seven years.However， 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 h

10、ad more chance to 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

11、 won the title of 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

12、 C.$350 D.$400 这类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。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,conclu

13、de 等词，这类题的设问方式主要有： 1.We 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 t

14、hat_. 8.It can be concluded 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 a

15、bout,what he really means is that_. 15.Whats the writers attitude/feeling towards.? 16.In the writers opinion,. 近年来，高考加大了对学生判断推理能力的考查。判断推理题要求在理解原文表面文字信息的基础上，作出一定判断和推论，从而得到文章的隐含意义和深层意义。推理题所涉及的内容可能是文中某一句话，也可能是某几句话，但做题的指导思想都是以文字信息为依据，既不能做出在原文中找不到文字根据的推理，也不能根据表面文字信息做多步推理。做题时要注意题干的语言形，如According to the p

16、assage.,It can be inferred from the passage that.；It can be concluded from the passage that.等，虽然从表面上看是问有关全文的题，但实际上不用看全篇，仍然只需要根据选项中的线索找到原文中与之相关的一句话或几句话，然后得出答案。针对推理题的不同形，可以采取以下做法：1.假如题干中有具体线索，根据具体线索找到原文相关句(一句或几句话)，然后做出推理；2.假如题干中无线索，如It can be inferred from the passage that.；It can be concluded from th

17、e passage that.等，先浏览一下4个选项，排除不太可能的选项，然后根据最可能的选项中的关键词找到原文相关句，作出推理；3.如果一篇文章中其他题都未涉及文章主旨，那么推理题，如infer,conclude题型，可能与文章主旨有关，考生应该定位到文章主题所在位置(如主题句出现处)；假如其他题已经涉及文章主旨，那么要求推断出来的内容可能与段落主题有关，如果如此，应该找段落主题所在处；如果不与段落主题有关，有时与全文或段落的重要结论有关，这时可以寻找与这些结论相关的原文表达。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

18、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 infer 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

19、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annealing 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

20、 after sheep，earns about 650 yuan a year.定语从句中 looks after sheep 就说明了 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 large 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

21、之间的短语很清楚地说明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 hu

22、ndred?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 permanent.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”。 【三年高考】 10、11 、12高考试题及其解析2018高考英语试题科普知识类 2018浙江卷
