语法复习六：状语从句,语法复习六：状语从句由从句担任的状语，在句子中可修饰谓语（或其它动词）、形容词、副词或是整个句子，它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。状语从句是一较大的语法项目，也是近几年高考题中常见的一个重要试点。高考中已考查了时间、让步、地点、条件、目的等状语从句，这些从句仍是今后高考热点，应作充分准备。同时对方式状语从句也应引起重视。（一）时间状语从句表示时间的状语从句可由when,as,while,whenever,after,before,till(until),since,once,assoonas(或themoment),bythetime,nosoonerthan,hardly(scarcely)when,everytime等引导。e.g.WhenIcameintotheoffice,theteacherswerehavingameeting.Hestartedassoonashereceivedthenews.Onceyouseehim,youwillneverforgethim.NosoonerhadIgonetobedthanIwenttosleep.,（二）原因状语从句原因状语从句是表示原因或理由的，引导这类从句的最常用的连词是because,since,as,nowthat（既然）等，for表示因果关系时（它引导的不是从句）为并列连词，语气不如because强。e.g.Heisdisappointedbecausehedidntgettheposition.Asitisraining,Iwillnotgoout.Nowthatyoumentionit,Idoremember.（三）地点状语从句引导地点状语从句的连词是where和wherever等。e.g.Sitwhereveryoulike.Makeamarkwhereyouhaveaquestion.（四）目的状语从句引导目的状语从句最常用的词（组）是so,sothat（从句谓语常有情态动词）,inorderthat,incase（以防，以免）等。,e.g.Speakclearly,sothattheymayunderstandyou.ShehasboughtthebookinorderthatshecouldfollowtheTVlessons.Heleftearlyincaseheshouldmissthetrain.（五）结果状语从句结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。由sothat（从句谓语一般没有情态动词）,sothat,suchthat等引导。e.g.Shewasill,sothatshedidntattendthemeeting.Hewassoexcitedthathecouldnotsayaword.Sheissuchagoodteacherthateveryoneadmiresher.,（六）条件状语从句条件状语从句分真实性（有可能实现的事情）与非真实性（条件与事实相反或者在说话者看来不大可能实现的事情）条件句。引导条件状语从句的词（组）主要有if,unless,so(as)longas,onconditionthat,so(as)faras,ifonly(=if)。注意：条件从句中的if不能用whether替换。e.g.Ifheisnotintheoffice,hemustbeoutforlunch.Youmayborrowthebooksolongasyoukeepitclean.SofarasIknow（据我所知）,hewillbeawayforthreemonths.Youcangoswimmingonconditionthat(=if)youdontgotoofarawayfromtheriverbank.Ifhehadcomeafewminutesearlier,hecouldhaveseenher.（七）让步状语从句让步状语从句可由although,though,as,evenif(though),however,whatever,whetheror,nomatterwho(when,what,)等引导。注意：as引导的让步状语从句一般是倒装的。,e.g.Thoughheisachild,heknowsalot.Childasheis,heknowsalot.Whatever(=Nomatterwhat)yousay,Illneverchangemymind.（八）方式状语从句方式状语从句常由as,asif(though),theway,ratherthan等引导。e.g.YoumustdotheexerciseasIshowyou.Heactedasifnothinghadhappened.（九）比较状语从句比较状语从句常用than,so(as)as,themorethemore等引导。e.g.Ihavemadealotmoremistakesthanyouhave.Hesmokescigarettesasexpensiveashecanafford.Thebusierheis,thehappierhefeels.,十）使用状语从句时要注意的几个问题1、在时间和条件（有时也在方式、让步等）从句中，主句是一般将来时，从句通常用一般现在时表示将来。e.g.Wellgooutingifitdoesntraintomorrow.IllwritetoyouassoonasIgettoShanghai.2、有些时间、地点、条件、方式或让步从句，如果从句的主语与主句主语一致（或虽不一致，是it），从句的谓语又包含动词be，就可省略从句中的“主语+be”部分。e.g.When(hewas)stillaboyoften,hehadtoworkdayandnight.If(youare)askedyoumaycomein.If(itis)necessaryIllexplaintoyouagain.,3、注意区分不同从句：引导的是什么从句，不仅要根据连词，还要根据句子结构和句意来判别。以where为例，能引导多种从句。e.g.Youaretofinditwhereyouleftit.（地点状语从句）Tellmetheaddresswherehelives.（定语从句，句中有先行词）Idontknowwherehecamefrom.（宾语从句）Wherehehasgoneisnotknownyet.（主语从句）Thisplaceiswheretheyoncehid.（表语从句）,练习:状语从句,一、用横线划出下列句子中的状语从句，并指出是哪种状语从句：1.,sheknowsalotofthings.2.Icandofortheclass,thehappierIllbe.3.Hetalks4.Heisagoodteacher5.Ishallgotothepark6.hadIgothomeitbegantorain.7.,thereislife.8.Hestudiedhard9.,Iwonttroubleyou.10.Illneverloseheart.,Childassheis,Themore,asif(asthough)heknewallaboutit.,such,thatthestudentsloveandrespecthim.,unlessitrains.,Nosooner,than,Wherethereiswater,sothathecouldcatchupwithhisclassmates.,Sinceyouareverybusy,Evenif(though)Ifail,让步,比较,方式,结果,条件,时间,地点,目的,原因,让步,答案,11.,youmustcontinue.12.Iwillfindher13.youdbetterhavedinnerwithus.14.Hewassoexcited15.Wemustdoeverything16.Indiaismuchbigger17.youarewarmlywelcome.18.youcancatchupwiththeotherclassmates.,Onceyoubeginthework,wherevershemaybe.,Nowthatyouvecome,thathecouldntfallasleep.,ashetellsus.,thanJapan.,Nomatterwhenyoucome,As(So)longasyouworkhard,时间,让步,原因,结果,方式,比较,让步,条件,答案,二、用适当的连词填空：1.Dr.Bethune(白求恩)cametoChina_hewasfifty.2.Hebegantowork_hegotthere.3.Letsbeginourmeeting_everyoneishere.4.IliketheEnglishpeople,_Idontliketheirfood.5._yougoinChina,youcanseesmilingfaces.6.Hedidntcometothelecture,_hewasverybusy.7._wehadenoughtime,wewalkedtothecinema.8.Theywillhelpyou_youmeetwithdifficulty.9._wecametotheuniversity,wehavelearntquitealot.,when,assoonas,as,though,Whwerever,because,Since,whenever,Since,答案,10.Ididntjointhemyesterdayevening_Ihadtogotoanimportantmeeting.11.Wewouldtrytogetacar_wecouldalltraveltogethermoreeasily.12.Shewouldntforgethermothersbirthday_sheseldomwrotetoherfamily.13.Weredoingeverythingwecantomakethingsaseasyforyou_wecan.14.Themeetingbecamesodisorderly_thespeakerhadtoshouttheaudiencedown.15.Hewasangrier_everbefore.16._youlockallthedoors,hecanstillmanagetogetin.17.Theboywassotired_hefellasleeponthebus.18.Hard_hetried,hecouldntforcethedooropen.,答案,because,sothat,though,as,that,than,Evenif,that,as,三、选择填空：1.Illletyouknow_hecomesback.A.beforeB.becauseD.although2.Shewillsingasong_sheisasked.B.unlessC.forD.since3.Wewillwork_weareneeded.A.wheneverB.becauseC.since4.Readitaloud_theclasscanhearyou.B.ifC.whenD.although5._yougo,dontforgetyourpeople.A.WheneverB.HoweverD.Whichever,C.assoonas,A.if,D.wherever,A.sothat,C.Wherever,答案,6.Itisabouttenyears_Imetyoulast.B.forC.whenD.as7.Theywillneversucceed,_hardtheytry.A.becauseC.whenD
