阅读理解精析之段落主旨一、段落主旨题.考察目的:段落主旨.题目特征：Whatisthisparagraghmainlyabout?Whatisthemainideaofthisparagraph?Themainideaoftheparagraphis..破解方法：找段落主题句a）段落首句是主题:如果段落后面的句子都是以代词或the开头，且段落中不再有转折，则段落直包就是主题。b）背景之后是主题:如果段落开头是例子、故事、经历、数字等,则这些信息之后容易出现主题句。c）段落尾句是主题:如果段落主体都在讲故事/经历/例子/数字/实验过程/引用的话，只有段落尾句是一个议论性的句子,则这个段落尾句就是主题（文章第1段往往是这样）；d）排比句后是主题:如果段落前两句有排比句的嫌疑，则这些排比句的后面才会出现段落主题。往往是段落尾句。e）but之后是主题:转折之后比较重要，无论什么时候，只要出现转折，前面一律作废！D上一自然段的主题句是主题:如果第N+1段话整体是一个故事/经历/例子/实验过程/引用的话，则一切其实都在解释第N段话的主题。我们把这种现象称为“伪分段现象”。【真题例题】（2020全国1卷D）Theconnectionbetweenpeopleandplantshaslongbeenthesubjectofscientificresearch.Recentstudieshavefoundpositiveeffects.AstudyconductedinYoungstown,Ohio,forexample,discoveredthatgreenerareasofthecityexperiencedlesscrime.Inanother,employeeswereshowntobe15%moreproductivewhentheirworkplacesweredecoratedwithhouseplants.Whatisthefirstparagraphmainlyabout?Anewstudyofdifferentplants.Abigfallincrimerates.Employeesfromvariousworkplaces.Benefitsfromgreenplants.【真题例题】（2020全国3卷B）Thecreativeteambehind"Apes"usedmotion-capture（动作捕捉）technologytocreatedigitalizedanimals,spendingtensofmillionsofdollarsontechnologythatrecordsanactofsperformanceandlaterprocessesitwithcomputergraphicstocreateafinalimage（图像）.Inthiscase,oneofarealistic-lookingape.25.Whatdoesparagraph2mainlytalkabout?A.Thecostofmaking"Apes.”Thecreationofdigitalizedapes.Thepublicityabout"Apes”Theperformanceofrealapes.【真题例题】Grown-upsareoftensurprisedbyhowwelltheyremembersomethingtheylearnedaschildrenbuthaveneverpracticedeversince.Amanwhohasnothadachancetogoswimmingforyearscanstillswimaswellaseverwhenhegetsbackinthewater.Hecangetonabicycleaftermanyyearsandstillrideaway.Hecanplaycatchandhitaballaswellashisson.AmotherwhohasnotthoughtaboutthewordsforyearscanteachherdaughterthepoemthatbeginsTwinkle,twinkle,littlestarnorrememberthestoryofCinderellaorGoldilocksandtheThreeBears.67.WhatisthemainideaofParagraph1?Peoplerememberwellwhattheylearnedinchildhood.Childrenhaveabettermemorythangrown-ups.Poemreadingisagoodwaytolearnwords.Storiesforchildrenareeasytoremember.【真题例题】（2017全国1卷A）♦SupportPacificScienceCenterSince1962,PacificScienceCenterhasbeeninspiringapassion（热情）fordiscoveryandlifelonglearninginscience,mathandtechnology.Today,PacificScienceCenterservesmorethan1.3millionpeopleayearandbringsinquiry-basedscienceeducationtoclassroomsandcommunityeventsalloverWashingtonState.It'sanamazingaccomplishmentandonewecannotachievewithoutgeneroussupportfromindividuals,corporations,andothersocialorganizations.VisittofindvariouswaysyoucansupportPacificScienceCenter.Whatisthepurposeofthelastpartofthetext?Toencouragedonations.Toadvertisecomingevents.Tointroducespecialexhibits.TotellabouttheCenter'shistory.TerrafugiaInc.saidMondaythatitsnewflyingcarhascompleteditsfirstflight,bringingthecompanyclosertoitsgoalofsellingtheflyingcarwithinthenextyear.Thevehicle-namedtheTransition-hastwoseats,fourwheelsandwingsthatfoldupsoitcanbedrivenlikeacar.TheTransition,whichflewat1,400feetforeightminuteslastmonth,canreacharound70milesperhourontheroadand115intheair.Itfliesusinga23-gallontankofgasandbums5gallonsperhourintheair.Ontheground,itgets35milespergallon.Whatisthefirstparagraphmainlyabout?ThebasicdataoftheTransitionTheadvantagesofflyingcars.Thepotentialmarketforflyingcars.ThedesignersoftheTransition.【真题例题】Meanwhile,thingsthatyoumightexpecttodiscouragespending
