定义：在复合句中由从句表示的状语称作状语从句，它可以用来修饰谓语（包括非谓语动词）、定语或状语，或是整个句子。准确掌握每一个连词的含义是掌握状语从句的关键。同时要注意主从句的时态呼应。状语一般分为九大类时间状语地点状语原因状语目的状语结果状语条件状语方式状语比较状语让步状语什么能做状语？•1副词•2介词短语：hetraveledinAfricaforsixweeks.•3形容词:myunclestoodthere,died.hefinallycameback,tiredandcold.•4with复合结构:withalotofworktodo,IthinkIhavenotimetoaccompanyyou.•5独立主格结构:helayonhisbed,hishandsunderhishead.•6非谓语动词：tododoing/havingdonedone•7状语从句1.时间状语从句：当…时候:when,while,as,一…就：themoment,theminute,assoonas,immediately,directly，nosooner…than,hardly…when每当：everytime,eachtime其他：before,after,till,until,since,When---当……时候,通常指某一特定的时间点，主句与从句的动作同时发生。WhenIopenedthewindow,Isawhimcomeup.WhenIhavetime,Iwillgotoseeyou.（主将从现）When---正在…的时候，突然…。在翻译的时候，when可以译成没想到或突然。Iwaswalkingalongthestreet,whenImethim.Iwasabouttofallasleepwhenmysistercamein.Iamgoingtoleavewhenthetelephonerings.When当从句是进行时，主句是一般时，往往表示不满。SomeoneknockedatthedoorwhenIwashavingbreakfast.WhenIwasleavingthehouse,thepostmanarrived.Whenthechildrenhadgonetobed,shebegantoprepareherlessons.When=afterWhile---在……期间，往往指一段时间。WhilewewereinAmerica,wesawhimtwice.Whileweweretalking,hecamein.Strikewhiletheironishot.While---表示一种不满情绪，意思是这边在干某种重要的事，而另一边在享受等。Wearecleaningtheclassroomwhiletheyareplayingthefootball.Thesoldierfacesthepowderwhilethebeautypowdertheface.WhileIamwashingthefloor,youcanbecleaningthewindows.As---一边……一边,随着Shewasdoingherhomeworkasshewaslisteningtothemusic.Asshegrewolder,shebecamemorebeautiful.As---当……时，指一个动作紧接着一个动作发生，从句通常用进行时。AsIwasgoingout,itbegantorain.IsawMaryasshewasgoingonthebus.Ashewaseatinghisbreakfast,heheardsomeoneknockatthedoor.SomeonepattedmeontheshoulderasIwasstandingbeforetheshopwindow.Themoment---一……就……=assoonas,immediately,---DidyouremembertogiveMarythemoneyyouowedher?---Yes,IgaveherthemomentIsawher.Not…until---直到……才Hedidn’tleavetheofficeuntilhefinishedthework.=Helefttheofficewhenhefinishedthework.Not…until可以和when互换Before---在……之前Thepassengersshouldarriveattheairportanhourbeforetheflightdeparts.Didyouworkasastewardessbeforeyoucometothiscompany?ItwasnotlongbeforeIforgotitall.(Itwas/willbe…before…是常用句型)HeranoffbeforeIcouldstophim.After---在……之后Thecustomerlefttheticketcounterafterhehadaquarrelwiththeticketagent.Theplanetookoffaftertheairtrafficcontrollergaveclearance.Since---自从……,通常主句用现在完成时IhaveneverbeenthereagainsinceIgraduatedfromtheuniversity.Thecaptainhastraveledalmosteverywhereintheworldsincehebecameapilot.Itisjustaweeksincewearrivedhere.(Itis/hasbeen…since…是常用句型）Assoonas---一……就……Jackwenttoschoolassoonashegotwell.I’llringyouupassoonasIgetananswerfromhim.Nosoonerthan---一……就……Nosoonerhadhearrivedthanhewentawayagain.nosooner…than…用于句首要求倒装Hardly…when…Scarcely…when…Onceyouseehim,youwillneverforgethim.Once---一但……就……Everytime,eachtime每次whenever每当Eachtimehecametotown,hewouldvisitourschool.Wheneverwemetwithdifficulties,theycametohelpus.2.条件状语从句引导状语从句的连接词有:If,unless,aslongas,incase,providedthat,onconditionthatIf---如果Ifyoudon’thurryup,youwillmisstheplane.Ifitsnowstomorrow,theflightwillbecanceled.Ifyouleaveat6o’clocktomorrowmorning,you’dbettergettobednow.Unless---如果不,除非=ifnotWecan’tgetthereontimeunlesswebooktheearliestflight=Wecannotgetthereontimeifwedon’tbooktheearliestflight.Don’ttroubletroubleunlesstroubletroublesyou.Hewillnotjoinusunlesshechangeshismind.Aslongas---只要Wewillsucceedaslongaswekeepontrying.Youcan’tplaygamesaslongasyouremembertherules.Amanisnotoldaslongasheisseekingsomething.As(so)faras---据……所知AsfarasIknow,hespeaksEnglishverywell.As/SofarasIknow,heisanexpertonDNA.Incase---假使,如果Theplanecannottakeoffincaseitrains.Sendusamessageincaseyouhaveanydifficulty.Providedthat如果,有时省略thatTheplanewillbeingoodconditionprovidedthatitistakencareofcarefully.Youcanbecomeastewardessprovidedthatyouareingoodshapeandyouhavegotthepropereducation.Onconditionthat---条件是…Hesaidthathewouldcometothemeetingonconditionthatnooneaskedhimtospeak.ThemotherpromisedtothesontobuyhimatoyairplaneonconditionthathepasseshisEnglishtest.注:主从句的动作发生在将来时，则主句用将来时,从句用一般现在时。Ifhearrivestomorrow,Iwillbewaitingforhimattheairport.Hesaidhewouldnotleaveunlessitwasfinenextday.3.地点状语从句地点状语从句只有两个连词:Where,whereverWhere---在……地方Putthemedicinewhereyoucaneasilygetit.Wherethathighbuildingstands,thereusedtobesomelow,desertedhouses.Wherethereisawill,thereisaway.Wherever---无论哪里Hefollowsherwherevershegoes.Whereveryouare,Iwillberighttherewaitingforyou.4.原因状语从句because,as,since,nowthat,和consideringthat,seeingthat这六个连词都用于表示表示原因,但在语气上一个比一个弱.Because---因为,通常从句放在主句后.MrSmithwasveryupsetbecausehecouldn’tfindhisluggage.Hesaidthathecouldn’tworkbecausethecomputerwasoutoforder.IsucceedbecauseIwilledit,Ineverhesitated.IdoitbecauseIlikeit.As---因为,通常放在句首Asitisquitewindytoday,hedecidesAsheishonestandmodest,allhisfriendslikehim.Since---既然因语气较弱,常译为既然Sinceeverybodyhascome,wecansetoff.Sincethepurserdidn’ttelluswhattodo,wecanrelax.Nowthat---既然Nowthatyouarehere,youcanjoinus.Nowthatallairlinesofferdiscountprices,weshoulddothesame.consideringthat---顾及到Consideringthattheyarejustbeginners,theyaredoingquiteagoodjob.seeingthat---由于Seeing(that)quiteafewpeoplewereabsent,wedecidedtoputthemeetingoff.5.结
