初中英语语法连词讲解及练习

初中英语语法连词讲解及练习（一）连词概述连词是连接单词、短语或句子的一种虚词。在句中不单独作句子成分。历年中考中常考并列连词and，but，neither…nor；从属连词nowthat，though，when。所以了解状语从句和宾语从句的真正意义有助于正确使用从属连词。（二）基础知识梳理1．并列连词用来连接彼此并列的词、短语或句子。并列连词有and，or，but，so，for，nor等。2．关联连词有both…and，either…or，neither…nor，notonly…butalso，aswellas，asmuchas等。3．连接性副词有however，therefore，besides，yet，anyway，still，allthesame等。4．并列连词和连接性副词存在以下的区别：1)连接两个独立的分句时，并列连词的位置只能放在它所引导的分句的句首，前面通常有逗号。如：Imustworkhard,forIstillhavealongwaytogo.Theyallwent,butIdidn'tgo.2)连接性副词的位置比较灵活，句中、句首、句末都可以。但是放在句首较为普遍。如：Motherwasill,therefore,shestayedathomeyesterday.=Motherwasill,shetherefore,stayedathomeyesterday.=Motherwasill,shestayedathomeyesterday,therefore.3)两个并列连词不可以连用。如：Hetriedhard．andbuthefailedtogetthejob.此句中的but应改为yet。因为and和but都是连词。5．从属连词是用来引导从句，如宾语从句、状语从句、定语从句等。从属连词有that，if,unless,whether,who,whose,what,which,where,than,when,while,as,since,though,although,because,before,after,until,assoonas,nowthat,so...that,sothat,as...as,(not)as/so…as如：Ifitsnowstomorrow，wewon'tgoonapicnic.（If引导条件状语从句）CouldyoutellmewhosePCitis（whose引导宾语从句）Themanwhoistalkingtomyclassteacherismyfather.（who引导定语从句）同步练习I.选择填空()1.LiMengpassedhismotherhiscup_______askedforsomemoretea.A.butB.orC.andD.if()2.Studyharder,______youwillfallbehindothers.A.andB.orC.butD.so()3.Thedoctorsareverytired,_______theyarestillworkingveryhard.A.butB.ifC.onlyD.when()4._____youcomeback,pleaseletmeknow.A.LaterB.UntilC.AsD.Assoonas()5.Hetoldus_______hewasovereightyyearsold.A.whereB.thenC.ifD.that()6.Don’tgohome_______youhavecleanedtheclassroom.A.byB.thenC.onlyD.until()7._______Sunday______MondayisOK.I’llbefreeduringthosetwodays.A.Neither…norB.Either…orC.Both…andD.Either…and()8.Wehaven’tseenhim________heleftlastyear.A.sinceB.whenC.asD.if()9.It’srainingnow,________youmusttaketheraincoatwithyou.A.forB.soC.orD.because()workharder,you’lldobetterinyoursubjects.A.IfB.BeforeC.AlreadyD.Whether()wasillyesterday,Ididn’tcometoschool.A.ForB.AsC.BecauseD.Since()oldmanwas_______pleased______hecouldnotsayaword.A.either…orB.neither…norC.notonly…butalsoD.so…that()isbigger,thesun_____theearth？A.butB.orC.andD.nor()14.Couldyoutellus_______yougrowapplesinyourcountryA.thatB.whetherC.whichD.what()knewnothingabouttheaccident_______hisfriendtoldhim.A.ifB.sinceC.untilD.because()answerthequestioninaloudvoice_____alltheclasscanhearyou.A.sothatB.so…thatC.thoughD.because()theolddaysthepoorchildrencouldn’tgotoschool.Theycould______read___writewhentheygrewup.A.both…andB.either…orC.notonly…butalsoD.neither…nor()Australiaisverylarge,thepopulationisquitesmall.A.ButB.OrC.IfD.Though()hereearlytomorrow,______you’llseeher.A.orB.andC.butD.because()she________Iamateacher.Wearebothstudents.A.orB.andC.norD.but()keptquiet______shebegantospeak.A.whenB.ifC.whetherD.or()Iamwashing,sheiscooking.A.WhileB.AfterC.BeforeD.Assoonas()hadtodoeverything________herhusbanddied.A.beforeB.afterC.whenD.while()hadstudiedRussianforthreeyears________shebegantolearnEnglish.A.beforeB.ifC.afterD.because()hashadanotherbaby________wemet.A.whenB.afterC.beforeD.since()knewnothingaboutit________hetoldme.A.ifB.afterC.untilD.because()’llringyouup,______Igetananswerfromhim.A.assoonasB.untilC.beforeD.because()couldn’tgoquickly______theroadwastooslippery.（滑）A.becauseB.assoonasC.ifD.until()itisfinetomorrow,I’llgotothepark.A.IfB.WhenC.AfterD.Before()don’tknow_______youlikesports.A.whetherB.weatherC.whenD.how()ismoreimportantinyourlife_______anyothermatter.A.asB.thanC.thenD.so()satinthefirstrow______shecouldseetheblackboardclearly.A.soB.sothatC.thatD.since()’llgotoseemysister_______IgettoNewYork.A.whileB.asC.assoonasD.since()were______manypainsinmychest______Icouldn’thelpcrying.A.so…asB.sothatC.so…thatD.such…that()yearshaspassed_____weleftourhometown.A.afterB.sinceC.asD.for()’msorry_________yourleghasbroken.A.whatB.thatC.ifD.when()youtellme_____theforeignerhavecomeornot？A.whatC.thatC.whetherD.when()wondered______hehadbeentoParis.A.thatC.whatC.ifD.where()youhurry,youwillbelateforschool.A.WhileC.UnlessC.ThatD.What()youpleaselookaftermydaughter______Igoshopping？A.whereB.whileC.thatD.thoughII.把下列句子变为同义句41.Mybrotherwenttothecinema,sodidI.__________mybrother_________Iwenttothecinema.42.Theboyissoyoungthathecantlookafterhimself.Theboyisn’t___________tolookafterhimself.43.Ifyouarelazy,youmaynotpasstheexam._________hard,_________youmaynotpasstheexam.44.Jacksmotheraskedhim,“Haveyoupackedyourthings”Jacksmotheraskedhim___________he__________packedhisthings.45.SherealizedHainanwasabeautifulplaceaftershereachedthere.She_________realizeHainanwasabeautifulplace_________shereachedthere.Ⅲ.选择所给的连词填空when,because,but,before,if,so...that,as…as,didn’t…until,and,after,or,since46.Hurryup,please!_______you’llbelateforschool.47.She________gotobed______hermothercameback.48.YesterdayJimdidn’tgotoseethefilm,________hemustgooverhislessons.49.Thestudentsweretalkingaboutthesportsmeeting_______theteachercamein.50.Iwas______tired________Icouldn’twalkanymore.51.Thisbuildingis_______tall________thatone.52.Tomwasillyesterday,________hestillwenttoschoolasusual.53.Heaskedme______Iwouldgotherewithh
