1.时间状语从句

(1)时间状语从句常用when,as,while,before,after,since,till,until,assoonas等连词来引导。例如：

Itwasraininghardwhengottoschoolyesterday.

Whilehewasdoinghishomework,thetelephonerang.

Ashewalkedalongthelake,hesanghappily.

HehadlearnedalittleChinesebeforehecametoChina.

Afterhefinishedmiddleschool,hewenttoworkinafactory.

(2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如：

I’llringyouupassoonasIgettoNewYork.

Iwilltellhimeverythingwhenhecomesback.

Hewon’tbelieveituntilheseesitwithhisowneyes.

(3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到……才……”,“在……以前不……”,谓语动词可用瞬间动词。例如：

Theyoungmanreadtillthelightwentout.

Let’swaituntiltherainstops.

Wewon’tstartuntilBobcomes.

Don’tgetoffuntilthebusstops.

2.条件状语从句

(1)条件状语从句通常由if,unless引导。例如：

Whatshallwedoifitsnowstomorrow？

Don’tleavethebuildingunlessItellyouto.

(2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如：

I’llhelpyouwithyourEnglishifamfreetomorrow.

Hewon’tbelateunlessheisill.

(3)“祈使句+and(or)+陈述句”在意思上相当于一个带有条件状语从句的复合句。例如：

Hurryup,oryou’llbelate.

=Ifyoudon’thurryup,you’llbelate.

Studyhardandyouwillpasstheexam.

=Ifyoustudyhard,youwillpasstheexam.

3.原因状语从句

(1)原因状语从句通常由because,since,as引导。例如：

Hedidn’tcometoschoolbecausehewasill.

Asitisraining,weshallnotgothezoo.

Sinceyoucan’tanswerthequestion,I’llasksomeoneelse.

(2)because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。As和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。例如：

------Whyaren’tgoingthere？

------BecauseIdon’twantto.

Ashehasnocar,hecan’tgetthereeasily.

Sincewehavenomoney,wecan’tbuyit.

(3)because和so不能同用在一个句子里。

4.结果状语从句

(1)结果状语从句由so…that,such…that,sothat引导。例如：

Heissopoorthathecan’tbuyabikeforhisson.

Sheissuchagoodteacherthateverybodylikesher.

Mypencilfellunderthedesk,sothatIcouldn’tseeit.

(2)so…that语such...that可以互换。例如：

在由so...that引导的结果状语从句中，so是副词，与形容词连用。其结构是:“...so+形容词(副词)+that+从句”。例如：

Hewassogladthathecouldn’tsayaword.

Thehallissobigthatitcanhold2,000people.

Motherlivessofarawaythatwehardlyeverseeher.二．例题演练一、用作时间状语1.典型例句Seeingthecat,themouseranoff.见到猫，老鼠就跑了。Theworkfinished,hewenthome.工作做完后，他就回家了。2.理解技巧分词(短语)用作时间状语通常可转换成时间状语从句(引导时间状语的从属连词需根据句意来确定)，如上面两句也可转换成：When[Assoonas]themousesawthecat,itranoff.Aftertheworkwasfinished,hewenthome.3.考题实例When_________differentcultures,weoftenpayattentiononlytothedifferenceswithoutnoticingthemanysimilarities.A.comparedB.beingcomparedC.comparingD.havingcompared【分析】此题答案选C，分词短语whencomparingdifferentcultures相当于时间状语从句whenwecomparedifferentcultures。二、用作原因状语1.典型例句Beingveryweak,shecouldn'tmove.她由于身体虚弱而不能行动。Hiscarbrokendown,hehadtowalk.他的车坏了，所以只好走路。Muchdiscouraged,shemovedontoLondon.她很沮丧，搬到了伦敦。2.理解技巧分词(短语)用作原因状语通常可转换成由as,because,since,nowthat等引导的原因状语从句，如上面三句也可转换成：Asshewasveryweak,shecouldn’tmove.Becausehiscarbrokenwasdown,hehadtowalk.Becauseshewasmuchdiscouraged,shemovedontoLondon.3.考题实例(1)_________withsomuchtrouble,wefailedtocompletethetaskontime.A.FacedB.FaceC.FacingD.Toface【分析】答案选A。现在分词短语facedwithsomuchtrouble可转换成原因状语从句becausewewerefacedwithsomuchtrouble。(2)_________forthebreakdownoftheschoolcomputernetwork,Alicewasinlowspirits.A.BlamingB.BlamedC.ToblameD.Tobeblamed【分析】答案选B。现在分词短语blamedforthebreakdownoftheschoolcomputernetwork可转换成原因状语从句becauseshewasblamedforthebreakdownoftheschoolcomputernetwork。三、用作条件状语1.典型例句Workinghard,youwillsucceed.如果努力工作，你就可以成功。Addingthemallup,wecanfindtheanswer.如果把它们加起来，我们就可以得到答案。United,westand;divided,wefall.团结则存，分裂则亡。Givenmoretime,wecouldhavedoneitbetter.如果多给点时间，我们可以做得更好。2.理解技巧分词(短语)用作条件状语通常可转换成由从属连词if引导的条件状语从句，如上面几句也可转换成：Ifyouworkhard,youwillsucceed.Ifweaddthemallup,wecanfindtheanswer.Ifweareunited,westand;ifwearedivided,wefall.Ifwehadbeengivenmoretime,wecouldhavedoneitbetter.3.考题实例_________time,he’llmakeafirst-classtennisplayer.A.HavinggivenB.TogiveC.GivingD.Given【分析】答案选D。give与其逻辑主语he是动宾关系，用过去分词，故选D。分词短语Giventime可转换成条件状语从顺Ifheisgiventime。四、用作让步状语1.典型例句Althoughlivingmilesaway,heattendedthecourse.虽然住在几英里以外，他仍去上课。Defeated,heremainedapopularboxer.虽然被击败了，他仍是一个受欢迎的拳击手。2.理解技巧分词(短语)用作让步状语通常可转换成由从属连词though,although,nomatter…等引导的让步状语从句，如上面两句也可转换成：Althoughhelivedmilesaway,heattendedthecourse.Thoughthewasdefeated,heremainedapopularboxer.3.考题实例Nomatterhowfrequently_________,theworksofBeethovenstillattractpeopleallovertheworld.A.performedB.performingC.tobeperformedD.beingperformed【分析】答案选A。现在分词短语performed在此相当于theyareperformed。Nomatterhowfrequentlytheyareperformed的意思是“无论它们(指贝多芬的作品)被演奏多少次”。五、用作伴随状语1.典型例句Hesatinthechairreadinganewspaper.他坐在椅子上看报。Don'tyousittheredoingnothing.别什么也不干坐在那里。Hecamein,followedbyhiswife.他走了进来，后面跟着他的妻子。2.理解技巧理解“伴随状语”的关键是要理解“伴随”二字。分词(短语)用作伴随状语时，它表示的动作伴随句子谓语动作同时发生，即句子谓语所表示的动作为主要动作，分词短语所表示的动作伴随性的次要动作。3.考题实例(1)Don’tsitthere_________nothing.Comeandhelpmewiththistable.A.doB.todoC.doingD.anddoing(2)Mycousincametoseemefromthecountry,_________meafullbasketoffreshfruits.A.broughtB.bringingC.tobringD.hadbrought(3)Wheneverhewasaskedwhyhewaslateforclass,hewouldanswercarelessly,always________thesamething.A.sayingB.saidC.tosayD.havingsaid(4)Weoftenprovideourchildrenwithtoys,footballsorbasketballs,_______thatallchildrenlikethesethings.A.thinkingB.thinkC.tothinkD.thought【分析】以上四题答案分别为CBAA。六、用作方式状语1.典型例句Heearnsalivingdrivingatruck.他靠开卡车谋取生。I'mreturningyouletterasrequested.我按要求给你退信。2.理解技巧分词(短语)用作方式状语与用作伴随状语的情形比较接近。有时用作方式状语的现在分词可以转换成bydoingsth的结构，如上面第一句也可换成：Heearnsalivingbydrivingatruck.七、用作结果状语Hefired,killingoneofthepassers-by.他开枪了，打死了一个过路人。Hedied,leavinghiswifewithfivechildren.他死了，留下他妻子和五个儿子。Itrainedandrained,vehiclesboggedandbridgeswashedout.雨不停地下，车辆陷入泥沼，桥梁被水冲去。2.理解技巧分词(短语)用作结果状语时，通常可转换成并列句，如上面两句也可转换成：Hefiredandkilledoneofthepassers-by.Hediedandlefthiswifewithfivechildren.Itrainedandrained,andvehicleswereboggedandbridgeswerewashedout.3.考题实例(1)Heglancedoverather,_________thatthoughshewastiny,sheseemedverywellputtogether.A.notingB.notedC.tonoteD.havingnoted【分析】答案选A，此句也可换成：Heglancedoveratherandnotedthatthoughshewastiny,sheseemedverywellputtogether.(2)Oilpriceshaverisenby32percentsincethestartoftheyear,_________arecordUS$abarrelonApril4.A.havereachedB.reachingC.toreachD.tobereaching【分析】答案选B，此句也可换成：Oilpriceshaverisenby32percentsincethestartoftheyearandreachedarecordUS$abarrelonApril4.三．重难点初中阶段常见状语从句用法见下表：
