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,nosooner…than,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.Heisdisappointedbecausehedidn'tgettheposition.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.44 （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）,so…that,such…that等引导。e.g.Shewasill,sothatshedidn’tattendthemeeting.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)youdon’tgotoofarawayfromtheriverbank.Ifhehadcomeafewminutesearlier,hecouldhaveseenher.（七）让步状语从句让步状语从句可由although,though,as,evenif(though),however,whatever,whether…or,nomatterwho(when,what,…)等引导。注意：as44 引导的让步状语从句一般是倒装的。e.g.Thoughheisachild,heknowsalot.Childasheis,heknowsalot.Whatever(=Nomatterwhat)yousay,I’llneverchangemymind.（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,themore…themore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.We’llgooutingifitdoesn’traintomorrow.I’llwritetoyouassoonasIgettoShanghai.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)necessaryI’llexplaintoyouagain.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。44 e.g.Youaretofinditwhereyouleftit.（地点状语从句）Tellmetheaddresswherehelives.（定语从句，句中有先行词）Idon’tknowwherehecamefrom.（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.Childassheis,sheknowsalotofthings.2.ThemoreIcandofortheclass,thehappierI’llbe.3.Hetalksasif(asthough)heknewallaboutit.4.Heissuchagoodteacherthatthestudentsloveandrespecthim.5.Ishallgototheparkunlessitrains.6.NosoonerhadIgothomethanitbegantorain.7.Wherethereiswater,thereislife.8.Hestudiedhardsothathecouldcatchupwithhisclassmates.9.Sinceyouareverybusy,Iwon'ttroubleyou.10.Evenif(though)Ifail.I’llneverloseheart.11.Onceyoubeginthework,youmustcontinue.12.Iwillfindherwherevershemaybe.13.Nowthatyou'vecome,you'dbetterhavedinnerwithus.14.Hewassoexcitedthathecouldn'tfallasleep.15.Wemustdoeverythingashetellsus.16.IndiaismuchbiggerthanJapan.17.Nomatterwhenyoucome,youarewarmlywelcome.18.As(So)longasyouworkhard,youcancatchupwiththeotherclassmates.44
