1、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 of the passage?W
2、hat 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 Paragraph.?The m
3、ain 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容，或以次要的事实或细节充当全
4、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“文章”将是什么内容，然后和原文
5、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、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，通常是主旨；反复出现的词语，一

70、more than usualBnot willing to share food with othersCnot conscious of the food qualityDnot fond of the food provided解析：A词义猜测题。根据第三段中的“.those given extralarge shares ate more than everyone else，but were none_the_wiserthey didnt fell fuller.”可知，那些被给以大份饭菜的食客比其他人吃得多，但他们没觉得更饱，这说明在黑暗的就餐环境下，食客并不清楚自己多吃了多少，
71、所以此处的none the wiser是“不清楚，不知道”之意。故选A项。10How could a fine dining shop make more profit?APlaying classical music.BIntroducing lemon scent.CMaking the light brighter.DUsing plates of larger size.解析：A细节理解题。根据第四段中的“when classical，rather than pop music was playing，diners spent more.”可知，当演奏古典音乐而不是流行音乐的时候，食客
72、们会花更多的钱。spent more 就是对题干中make more profit的语意转化。故选A项。11What does the last paragraph talk about?ATips to attract more customers.BProblems restaurants are faced with.CWays to improve restaurants reputation.DCommon misunderstandings about restaurants.解析：D段落大意题。根据最后一段首句中的“things that you might expect to discourage spendingbadtables，crowding，high pricesdont necessarily”可知，你可能认为会打消你消费的念头的东西位置“不好”的桌位、拥挤和价格高未必如此(指在某些人看来，这些不利因素未必不会带来利润的增加)。由此可知，作者认为这些对于餐馆的常见观点是一种误解，故选D项。
