学习必备欢迎下载一、强调句(一)强调句句型1、陈述句的强调句型:Itis/was+被强调部分(通常是主语、宾语或状语)+that/who(当强调主语且主语指人)+其它部分。e.g.ItwasyesterdaythathemetLiPing.2、一般疑问句的强调句型:同上,只是把is/was提到it前面。e.g.WasityesterdaythathemetLiPing?3、特殊疑问句的强调句型:被强调部分(通常是疑问代词或疑问副词)+is/was+it+that/who+其它部分?e.g.Whenandwherewasitthatyouwereborn?4、强调句例句:针对ImetLiMingattherailwaystationyesterday.句子进行强调。强调主语:ItwasIthat(who)metLiMingattherailwaystationyesterday.强调宾语:ItwasLiMingthatImetattherailwaystationyesterday.强调地点状语:ItwasattherailwaystationthatImetLiMingyesterday.强调时间状语:ItwasyesterdaythatImetLiMingattherailwaystation.5、注意:构成强调句的it本身没有词义;强调句中的连接词一般只用that,who,即使在强调时间状语和地点状语时也如此,that,who不可省略;强调句中的时态只用两种,一般现在时和一般过去时。原句谓语动词是一般过去时、过去完成时和过去进行时,用Itwas…,其余的时态用Itis…。(二)not…until…句型的强调句1、句型为:Itis/wasnotuntil+被强调部分+that+其它部分e.g.普通句:Hedidn’tgotobeduntil/tillhiswifecameback.强调句:Itwasnotuntilhiswifecamebackthathewenttobed.2、注意:此句型只用until,不用till。但如果不是强调句型,till,until可通用;因为句型中Itis/wasnot…已经是否定句了,that后面的从句要用肯定句,切勿再用否定句了。(三)谓语动词的强调1、Itis/was…that…结构不能强调谓语,如果需要强调谓语时,用助动词do/does或did。e.g.Dositdown.务必请坐。Hedidwritetoyoulastweek.上周他确实给你写了信。Dobecarefulwhenyoucrossthestreet.过马路时,务必(千万)要小心啊!2、注意:此种强调只用do/does和did,没有别的形式;过去时用did,后面的谓语动词用原形。二、It的用法(一)作人称代词1、it代替前面(或后面)的单数名词或分句等所表示的事物。e.g.Youcannoteatyourcakebuthaveit.(it代替前面的cake)Althoughwecannotseeit,thereisairallaroundus.(it代替后面的air)Theysayhehaslefttown,butIdon’tbelieveit.(it代替前面They…town分句中的情况)2、代替有生命但不能或不必分阴阳性的东西(包括婴儿)。e.g.Yesterdaywesawabigtree.Itwasfullytwentymetreshigh.(it代替前面的tree)Thebabycriedbecauseitwashungry.(it代替前面的baby)3、在某些习惯说法中,可以代替人。e.g.----Someoneisknockingatthedoor,Peter.----Whoisit?----It’sme.----Whoaresinging?----Itisthechildren.学习必备欢迎下载----Thelightisstilloninthelab.Itmustbethethird-yearstudentsdoingtheexperiment.4、it与one的区别:这两个词都可以代表前面说过的名词,但it用于同名同物的场合;one则用于同名异物的场合。e.g.----Doyoustillhavethebicycle?----No,Ihavesoldit.----Isthisknifeyours?----No.ItisXiaoZhang’s.Mineistheoneonthedesk.5、it与that的区别:两词都可代替某一特定名词,但that指同一类,并非同一个。e.g.TheclimateofSouthChinaismild(温和的);Ilikeitverymuch.(it指theclimateofSouthChina)TheclimateofSouthChinaismuchbetterthanthatofJapan.(that指theclimate)(二)作无人称代词it作无人称代词时,除了句中找不到它所代表的词语外,另一个特点是它后面的内容都是表示天气、时间、距离、度量衡及情况等。Itisfine(rainy,windy,etc.).Itisnoon.Itisahalfhour’swalktothefactory.Itiseighteensquaremetresinarea.Whatdoesitmatter?(三)作强调词,构成强调结构用以帮助改变句子结构,使句子的某一成分受到强调。“Itis(was)+所强调的成分+that(who)+其它成分。”在这个句型中,it本身没有词义。详见“一、强调句”。(四)引导词it作形式主语(宾语)为了使句子平衡,常采用形式主语(或宾语)it,而把真正的主语(或宾语)置于句子后面。通常引导词it与它所代替的句子成分中间要夹有某些词。e.g.Ittakeshalfanhourtogothereonfoot.(It与togothereonfoot之间夹有takeshalfanhour四个词)WethoughtitstrangethatMrSmithdidnotcomelastnight.(it与that从句中间夹有strange)但有时it与所替代部分之间并不夹有其它词。e.g.Youmaydependonitthattheywillsupportyou.(因为介词on之后一般不直接接that引导的宾语从句。注意:it不是多余的,不能当作错句)练习一、强调句、It的用法1.Mybikeismissing.Ican’tfind____anywhere.A.oneB.onesC.itD.that2.----Who’sthat?----____ProfessorLi.A.That’sB.It’sC.He’sD.This’s3.____wasJanethatIsawinthelibrarythismorning.A.ItB.HeC.SheD.That4.----Haveyoueverseenawhalealive?----Yes,I’veseen____.A.thatB.itC.suchD.one5.Thecolorofmycoatisdifferentfrom____ofyours.A.thisB.thatC.itD.one6.____willdoyougoodtodosomeexerciseeverymorning.A.ItB.ThereC.ThoseD.You7.Wethink____ourdutytopaytaxestoourgovernment.A.thatB.thisC.itsD.it学习必备欢迎下载8.TheclimateofShanghaiisbetterthan____ofNanjing.A.thatB.itC.whichD.what9.____fouryearssinceIjoinedtheArmy.A.TherewasB.ThereisC.ItwasD.Itis10.Howlong____tofinishthework?A.you’lltakeB.you’lltakeitC.willittakeyouD.willtakeyou11.ItwasthroughXiaoLi____IgottoknowXiaoWang.A.whoB.whomC.howD.that12.Itwasinthericefields____wehadourleaguemeeting.A.whereB.thatC.inwhichD.onwhich13.ItwasonOctober1st____newChinawasfounded.A.whichB.whenC.asD.that14.Wasitbecausehewasill____heaskedforleave?A.andB.thatC.that’sD.so15.Maryspeaksinalowvoice;____isdifficulttoknowwhatsheissaying.A.itB.thatC.soD.she16.Itwas____ImetMrGreeninShanghai.A.manyyearsthatB.manyyearsbeforeC.manyyearsagothatD.manyyearswhen17.____isnoteverybody____candrawsowell.A.It,allB.It,thatC.There,whoD.There,that18.So____thatnofishcanliveinit.A.shallowisthelakeB.thelakeisshallowC.shallowthelakeisD.isthelakeshallow三、省略为了使讲话和行文简洁,句中某些成分有时可省略。省略可分以下几种情况:(一)简单句中的省略1、省略主语:祈使句中主语通常省略。其它省略主语多限于少数现成的说法。e.g.(I)Thankyouforyourhelp.(括号内为省略的词语,下同)(I)seeyoutomorrow.(It)Doesn’tmatter.2、省略主谓语或主谓语的一部分。e.g.(Thereis)Nosmoking.(Isthere)Anythingwrong?Why(doyou)notsayhellotohim?3、省略作宾语的不定式短语,只保留to。e.g.----Areyougoingthere?----I’dliketo(gothere).Hedidnotgivemethechance,thoughhehadpromisedto(givemethechance).注意:如果该宾语是be动词或完成时态,则须在to之后加上be或have。e.g.----Areyouanengineer?----No,butIwanttobe.----Hehasn’tfinishedthetaskyet.----Well,heoughttohave.4、省略表语。e.g.----Areyouthirsty?----Yes,Iam(thirsty).5、同时省略几个成分。e.g.Let’smeetatthesameplaceas(wemet)yesterday.----Haveyoufinishedyourwork?----(Ihave)Not(finishedmywork)yet.(二)并列句中的省略两个并列分句中,后一个分句常省略与前一分句中相同的部分。学习必备欢迎下载e.g.Myfatherisadoctorandmymother(is)anurse.Istudyatcollegeandmysister(studies)athighschool.(三)主从复合句中的省略1、主句中有一些成分被省略。e.g.(I’m)Sorrytohearthatyouareill.(Itisa)Pitythathemissedsuchagoodchance.2、省略了一个从句或从句的一部分,用so或no
