语法5状语从句2.ppt

英语（2）,48,30,李敏,原因状语从句,引导原因状语从句的连词(词组)主要有以下几类。1.连词：because,since,as,for,nowthat(既然)e.g.Idecidedtogowiththem,mainlybecauseIhadnothingbettertodo.Nowthateverybodyhascome,letsbeginourmeeting.because,since,as,for的区别：这几个词都是表示“原因”的连词，语气由强至弱依次为becausesinceasfor。because表示直接原因，因此用why开头的疑问句，通常用because回答。since和as表示显然的或已为人所知的理由。for表明附加或推断的理由，它所引导的分句只能放在句子后部，其间用逗号隔开。,2.特殊引导词：seeingthat(既然)；nowthat(既然)；inthat(因为，在于)；consideringthat(考虑到，因为)；giventhat(鉴于)e.g.Seeingthatitisten,weshallnotwaitforheranylonger.Giventhatsheisinterestedinchildren,Iamsureteachingistherightcareerforher.Consideringhesonlytenyearsold,theneighborswonttakehimtocourt.,目的状语从句,引导目的状语从句的连词(词组)有sothat(为了),inorderthat(为了),forfearthat(以免),lest(以免),incase(以免)等。1.sothat和inorderthatsothat比inorderthat更为常用，尤其在非正式的文体中。当主句中的动词为现在时、现在完成时或将来时的时候，sothat和inorderthat后面可以跟may,can或will。e.g.Usuallywekeepenoughsugarandotheritemsinthekitchensothat/inorderthatwecan/may/willhavethemwhenweneed.当主句中的动词为一般过去时、过去完成时的时候，sothat和inorderthat后面可以跟should,could,would或might。e.g.Iarrivedearlysothat/inorderthatIshould/could/might/wouldhaveagoodviewoftheparade.,2.lest,forfearthat和incase这三个连词(词组)都表示“以防，以免”。后面可以用情态动词may,might,should等。incase后面的从句中可以用现在时表示可能，用“should+动词原形”表示可能性较小；forfearthat后面常用might；lest引导的从句中通常用虚拟语气结构“should+动词原形”。e.g.IllgetsomebeerincaseBillshouldcome.Takecareincasethehousemaycatchfire.Iwillkeepquiet,lestIshoulddisturbyou.,结果状语从句,引导结果状语从句的连词(词组)有sothat(结果),sothat(如此以致于),suchthat(如此以致于),withtheresultthat(结果),tothedegreethat(如此以致于)等。e.g.Healwaysstudiedsohardthathemadegreatprogress.Itssuchagoodchancethatwemustnotmissit.Annwasntatschoollastweek,withtheresultthatshemissedanimportanttest.sothat和suchthat的区别：so是副词，修饰形容词或副词；such是形容词，修饰名词或名词词组，后面跟“(a/an)+(形容词)+名词”结构。e.g.ItissuchniceweatherthatIdliketotakeawalk./TheweatherissonicethatIdliketotakeawalk.Mikeissohonestamanthatweallbelievehim./Mikeissuchanhonestmanthatweallbelievehim.,条件状语从句,引导条件状语从句的连词主要有：1.if(如果),unless(除非)e.g.Ifitdoesntraintomorrow,wewillgohiking.在条件状语从句中，如果主句是将来时态，从句可用一般现在时表示将来时间Youwillbelateunlessyouleaveimmediately.2.as/solongas(只要),whetherornot(无论是或)e.g.Youwillcertainlysucceedsolongasyoukeepontrying.ItseemsthatmymotherwillcriticizemeeverydaywhetherIviding/providedthat(假如),suppose/supposingthat(假如),onconditionthat(如果，在条件下)e.g.Providedthatthereisnoopposition,weshallholdthemeetinghere.Supposethecarwouldbreakdownagain,whatshouldwedo?,Exercises,1.1)Illletyouknow_hecomesback.A)unlessB)becauseC)assoonasD)although2)_youreturnthedictionarytothelibraryimmediately,youwillbefined.（罚款）A)IfB)UntilC)ProvidedD)Unless3)_stillhalfdrunk,hemadehiswayhome.A)WhenB)AslongasC)ProvidingD)For4)Shewas_tired_shecouldnotmoveaninch.A)so;thatB)such;thatC)very;thatD)so;as,5)Speaktohimslowly_hemayunderstandyoubetter.A)sinceB)sothatC)forD)because6)_wemightgetthereontime,weshouldsetoutearly.A)SinceB)NowthatC)InorderthatD)Supposingthat7)Takeanumbrellawithyou_itshouldrain.A)sothatB)asC)ifD)incase8)Iwrotedownhisnameandaddress_Imightforgetit.A)inorderthatB)forfearthatC)sothatD)withtheresultthat9)_yousayso,Isupposeitistrue.A)SinceB)UnlessC)UntilD)So10)Theoryisvaluable_itcanprovideadirectionforpractice.A)incaseB)thoughC)sothatD)inthat,2.1)He_didntgo_(go)homeuntilhecleanedupalltheofficesyesterday.2)Tomwillcallmeassoonashe_arrives_(arrive)inShanghai.3)It_musthaverained_(rain)lastnight,fortheroadiswet.4)Shedance
