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Thebesttitleofthepassageis________.Whichofthefollowingisthebesttitleofthepassage?Whatwouldbethebesttitleforthepassage?Themostappropriatetitleofthepassageis________.2．文章大意题What'sthemainidea/pointofthepassage?Thepassageismainlyabout________.Whatisthetextmainlyabout?Thegeneral/mainideaofthepassageisabout________.3．段落大意题WhatdoestheauthortellusinParagraph...?Themainideaofthesecondparagraphprobablyis________.Thefirstparagraphismainlyabout________.WhichofthefollowingcanbestsummarizePar.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Ⅱ，阅读D)Bacteriaareanannoyingproblemforastronauts.Themicroorganisms(微生物)fromourbodiesgrowuncontrollablyonsurfacesoftheInternationalSpaceStation，soastronautsspendhourscleaningthemupeachweek.HowisNASAovercomingthisverytinybigproblem？It'sturningtoabunchofhighschoolkids.Butnotjustanykids.ItisdependingonNASAHUNCHhighschoolclassrooms，liketheonescienceteachersGeneGordonandDonnaHimmelbergleadatFairportHighSchoolinFairport，NewYork.HUNCHisdesignedtoconnecthighschoolclassroomswithNASAengineers.Forthepasttwoyears，Gordon'sstudentshavebeenstudyingwaystokillbacteriainzerogravity，andtheythinkthey'reclosetoasolution(解决方案)．“Wedon'tgivethestudentsanybreaks.TheyhavetodoitjustlikeNASAengineers，”saysFlorenceGold，aprojectmanager.“Therearenotests，”Gordonsays.“Thereisnogradedhomework.Therealmostarenogrades，otherthan‘Areyouworkingtowardsyourgoal？’Basically，it's‘I'vegottoproducethisproductandthen，attheendoftheyear，presentittoNASA.’Engineerscomeandreallydoaninpersonreview，and...it'snotaverynicethingattimes.It'sahardbusinessreviewofyourproduct.”GordonsaystheHUNCHprogramhasanimpact(影响)oncollegeadmissionsandpracticallifeskills.“ThesekidsaresoabsorbedintheirstudiesthatIjustsitback.Idon'tteach.”Andthatannoyingbacteria？GordonsayshisstudentsareemailingdailywithNASAengineersabouttheproblem，readyingaworkablesolutiontotestin...
