语法精典讲解词法部分（连词）08连词的用法【连词的用法】（讲解1）连词主要分并列连词和从属连词两类,是种虚词不能独立担任句子成分而只起连接词与词、短语与短语、句与句的作用.并列连词用来连接平行的词、词组和分句.如:and,but,or,nor,so,therefore,yet,however,for,hence,aswellas,bothand,notonly...butalso,eitheror,neithernor,(and)then等等.1、并列连词与并列结构:1）and与or.（错）Theysatdownandtalkaboutsomething.（错）Theystartedtodanceandsang.（错）Isawtwomensittingbehindandwhisperthere.（对）Theysatdownandtalkedaboutsomething.（对）Theystartedtodanceandsing.（对）Isawtwomensittingbehindandwhisperingthere.解析:第一句:and连接两个并列的谓语,所以talk应改为talked.第二句:and连接两个并列的动词不定式,第二个不定式往往省略to,因此sang应改为sing.第三句:and连接感观动词saw后面的用作宾补的两个并列分词结构,因此whisper应改为whispering.注意:and还可以和祈使句或名词词组连用表示条件.（or也有此用法）Makeupyourmind,andyou'llgetthechance.=Ifyoumakeupyourmind,you'llgetthechance.Onemoreeffort,andyou'llsucceed.=Ifyoumakeonemoreeffort,you'llsucceed.08连词的用法【连词的用法】（讲解1）2）bothand两者都.Sheplays（both）thepianoandtheguitar.3）notonlybut（also）,aswellas.Sheplaysnotonlythepiano,but（also）theguitar.注意:notonly?butalso关联两个分句时,一个分句因有否定词not而必须倒装.Notonlydoeshelikereadingstories,butalsohecanevenwritesome.4）neithernor既不...也不....谓语动词采用就近原则,与nor后的词保持一致.Neitheryounorheistoblame.08连词的用法【连词的用法】（讲解1）2、比较and和or.并列结构中,or通常用于否定句,and用于肯定句.但有时and也可用于否定句.请注意其不同特点:Thereisnoairorwaterinthemoon.Thereisnoairandnowateronthemoon.在否定中并列结构用or连接,但含有两个否定词的句子实际被看作是肯定结构,因此要用and.典型例题-Idon'tlikechicken__fish.-Idon'tlikechicken,__Ilikefishverymuch.A.and;andB.and;butC.or;butD.or;and答案C.否定句中表并列用or,but表转折.判断改错:（错）Wewilldiewithoutairandwater.（错）Wecan'tlivewithoutairorwater.（对）Wewilldiewithoutairorwater.（对）Wecan'tlivewithoutairandwater.08连词的用法【连词的用法】（讲解1）3、表示选择的并列结构.1）or意思为“否则”.Imustworkhard,orI'llfailintheexam.2）eitheror意思为“或者...或者...”注意谓语动词采用就近原则.EitheryouorIamright.4、表示转折或对比.1）but表示转折,while表示对比.Somepeoplelovecats,whileothershatethem.典型例题Wouldyouliketocometodinnertonight?I'dliketo,__I'mtoobusy.A.andB.soC.asD.but答案D.but与前面形成转折,符合语意.而表并列的and,结果的so,原因的as都不符合句意.2）not和but意思为“不是...而是...”not和but后面的用词要遵循一致原则.Theywerenotthebonesofananimal,but（thebones）ofahumanbeing.08连词的用法【连词的用法】（讲解1）5、表原因关系.1）for.判断改错:（错）Forheisill,heisabsenttoday.（对）Heisabsenttoday,forheisill.for是并列连词,不能置于含两个并列分句的句子的句首,只能将其放在两个分句中间.2）so,therefore.Hehurthisleg,sohecouldn'tplayinthegame.注意:A.两个并列连词不能连用,但therefore,then,yet.可以和并列连词连用.YoucanwatchTV,andoryoucangotobed.Hehurthisleg,andso/andthereforehecouldn'tplayinthegame.B.although?yet?#65292;但although不与but连用.（错）Althoughhewasweak,buthetriedhisbesttodothework..（对）Althoughhewasweak,yethetriedhisbesttodothework.08连词的用法【连词的用法】（讲解1）6、比较so和such.其规律由so与such的不同词性决定.①such是形容词,修饰名词或名词词组;②so是副词,只能修饰形容词或副词,so还可与表示数量的形容词many,few,much,little连用,形成固定搭配.so+adj.such+a（n）+n.so+adj.+a（n）+n.such+n.（pl.）so+adj.+n.（pl.）such+n.（pl.）so+adj.+n.（不可数）such+n.（不可数）sofoolishsuchafoolsoniceaflowersuchaniceflowersomany/fewflowerssuchniceflowerssomuch/littlemoney.suchrapidprogresssomanypeoplesuchalotofpeoplesomany已成固定搭配,alotof虽相当于many,但alotof为名词性的,只能用such搭配；so...that与such...that之间的转换既为so与such之间的转换.08连词的用法连词用法（练习1）1.__John__Iarepolicemen.A.Neither...norB.Either...orC.Both...andD.Notonly...butalso2.MrSmithteaches__well__hislessonsarenoteasilyforgotten.A.very...thatB.quite...butC.so...asD.so...that3.Hedidn'tgotosleep__hefinishedhishomework.A.tillB.beforeC.afterD.until08连词的用法连词用法（练习1）4.Ididn'tbuythedictionaryyesterday__myauntwouldgivemeone.A.untilB.becauseC.ifD.before5.Therunnerfell__hequicklygotupandwentonrunning.A.orB.andC.butD.down6.Waitformeintheroom__Icomeback.A.untilB.andC.soD.or08连词的用法连词用法（练习1）7.I'llreturnthebookstothelibrary__soonaspossible.A.asB.soC.justD.but8.Goalongtheroad,__you'llfindthemarketattheendofit.A.whenB.andC.orD.though9.You'llbelate__youdon'tgetupearlytomorrowmorning.A.ifB.whenC.beforeD.until08连词的用法连词用法（练习2）1.MrLinoftencomestotheparktodomorningexercieseatthistimeof__day.A.theB.aC./D.an2.Thisis__business,notmine.A.MrYangandMrZhang'sB.MrYangandMrZhangC.MrYang'sandMrZhangD.MrYang'sandMrZhang's3.Ihavegot__newsfrommyfriend.Doyouwanttoknow?A.averygoodB.anyC.apieceofD.twopieces08连词的用法连词用法（练习2）4.She__athickcoattoday,thoughitisn'tverycold.A.iswearingB.putonC.dressedD.isdressing5.Thatwomanisverytired,soshe__.A.stoppedtoworkB.stoppedhavingagoodrestC.stoppedtohavearestD.stoppedtoworking6.-Hello,whoareyou__?-Mymother.A.waitingB.waitingforC.findingD.looking08连词的用法连词用法（练习2）7.MyunclewenttoMoscowtodosomebusinessthreemonths__?A.beforeB.laterC.agoD.after8.Edisonwasclevererthan__studentsinhisclass,buthisteacherdidn'tknowthis.A.alltheB.otherC.anotherD.theothers9.Idon'tknowwhereJackisnow.__-inthecinema.A.MaybeheB.MaybeheC.HemightbeD.Hemaybe08连词的用法连词用法（练习2）10.Itwas__dark__wecouldn'tseeanythingclearly.A.very,thatB.too,toC.so,asD.so,that11.Therearetwodictionariesonhisdesk,but__ofthemisusefultome.A.allB.neitherC.bothD.either12.__Isawhimdrivingacaracrossthestreet.A.RightnowB.JustamomentC.RightawayD.Justnow08连词的用法连词用法（练习2）13.Shewillbebackbyairfromshanghai__.A.inaweekB.afteraweekC.aweeklaterD.untilaweek14.Youmaypayattentiontoyourwriting__nobodycanunderstandwhatyouwanttowrite.A.butB.andC.orD.that15.Thetestis__easierand__interestingthanthatone.A.more,muchB.much,moreC.more,mor
