高考英语复习考点精析主旨大意题.docx

1、高考英语复习考点精析主旨大意题第三讲主旨大意题整体感知明方向主旨大意题是阅读理解中考生失分最多的题目，因为该类试题不仅考查考生略读文章、领会大意的能力，也对考生的归纳、概括能力提出了较高的要求。文章中没有明显的解题依据，需要考生从文章中提炼、抽取一些关键词、主干句进行加工概括，才能归纳出文章的主旨。此类题目可分为三大类，即标题归纳题、文章大意题和段落大意题。要做好主旨大意题，我们首先必须了解其正确选项和干扰选项的特征。常见设问方式1标题归纳题The best title of the passage is _.Which of the following is the best title o

2、f the passage?What would be the best title for the passage?The most appropriate title of the passage is _.2文章大意题Whats the main idea/point of the passage?The passage is mainly about _.What is the text mainly about?The general/main idea of the passage is about _.3段落大意题What does the author tell us in P

3、aragraph.?The main idea of the second paragraph probably is _.The first paragraph is mainly about _.Which of the following can best summarize Par.1？正确选项特征干扰选项特征1.涵盖性强，覆盖全文或全段。2.确定的范围恰当，既不太大，也不太小。3.精确性强，不会改变语言表意的程度及色彩。1.过于笼统，不知所云所给选项内容概括的范围过大，超出文章所述内容。2.以偏概全，主次不分所给选项只阐述了文章的一部分内容，或以文章中的细节信息或个别词为选项的设置内

4、容，或以次要的事实或细节充当全文的主要观点。3.移花接木，偷换概念所给选项被命题者有意识地把本属于A的内容放在B上，若不留神，极易选错答案。4.无中生有，生搬硬套所给选项的关键词语虽然在文章中谈到了，但经过仔细阅读分析之后，发现选项的内容与文章的内容毫无联系。分类例析通技法标题归纳题解题攻略理解标题的3大特点，巧用3大方法确定文章标题一个好的标题应具备三大特点：1概括准确而又简短；2针对性标题外延正好与文章内容相符；3醒目能引发读者的阅读欲望。因此有必要掌握以下三大方法：1正面肯定法：在理解文章主旨的基础上，揣摩哪个选项能准确概括主旨；2反面否定法：撇开原文，拿各个备选项去设想用它们写出来的“

5、文章”将是什么内容，然后和原文章对照，一一排除不符选项；3研读备选项本身：研读备选项里面的中心词、修饰词的变化、结构、概括性等。典例(2019全国卷，阅读D)Bacteria are an annoying problem for astronauts.

12、法是建立在理解具体段落中心的基础上的。找出每小段的主题句，各段的主题句常在该段的首句或尾句，各段主题句的整体归纳便是文章的中心思想。有的文章无明显主题句，主题句隐含在段意之中，这就需要进一步加工概括。观察全文的结构安排，理解文章的“重心”和支撑性细节。 用浏览法(skimming)，即快速阅读文首、文尾，或每段的首句和尾句等，搜索主题线索和主题信息的方法可以快速找到主题句。 以下是找主题句的四个小窍门：1段落中出现表示转折的词语(如however，but，in fact，actually等)时，该句很可能是主题句。2首段出现疑问句时，对该问题的回答很可能就是文章主旨。3作者有意识地重复的观点，

13、通常是主旨；反复出现的词语，一般为体现文章主旨的关键词。4表示总结或结论的句子常包含therefore，thus，in short，conclude，conclusion等词。典例(2019全国卷，阅读C)Marian Bechtel sits at West Palm Beachs Bar Louie counter by herself，quietly reading her ebook as she waits for her salad.What is she reading？None of your business！Lunch is Bechtels “me” time.And l

21、式行文，这种结构的段落一般会在一段中讨论两个平行的内容，整个段落可以从中间处分开，前后是平行关系，这样的段落结构对应的答案通常也会是很明显的并列关系；(6)如果对比各事物，那么它们的共同点或不同点就是该段大意。方法2揣摩段落大意有时，作者可能不直接写出主题句，而是通过各种方法暗示给读者，这就需要充分发挥读者的想象力与判断力，揣摩段落大意。典例(2019江苏卷，阅读B节选)Most of us，when we talk about volcanoes，think of the classic cone(圆锥体)shapes of a Fuji or Kilimanjaro，which are c
