济南新年华教育初中英语语法讲义第八讲2009年英语复习八:状语从句的考点讲解和训练八、状语从句【考点直击】1.时间状语从句2.条件状语从句3.原因状语从句4.结果状语从句5.比较状语从句6.目的状语从句7.让步状语从句8.地点状语从句【名师点睛】用来修饰主句中的动词,副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状语从句,地点状语从句,条件状语从句,原因状语从句,结果状语从句,比较状语从句,目的状语从句,让步状语从句。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.第5页 济南新年华教育初中英语语法讲义第八讲(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.在由such…that引导的结果状语从句中,such是形容词,它修饰的可以是单数或复数可数名词,也可以是不可数名词;名词前面可以带形容词,也可不带。如果是单数可数名词,前面需加不定冠词a或an。例如:Itwassuchahotdaythatnobodywantedtodoanything.Hehadsuchlongarmsthathecouldalmosttouchtheceiling.Hemadesuchrapidprogressthathedidverywellinthemid-term.有时上述两种结构是可以互换的。例如:Itwassuchawonderfulfilmthatallofuswantedtoseeitagain.=Thefilmwassowonderfulthatallofuswantedtoseeitagain.Itissuchanimportantmatchthatnobodywantstomissit.=Thematchissoimportantthatnobodywantstomissit.(3)如果名词前由many,much,little,few等词修饰时,只能用so,不用such。例如:Soonthereweresomanydeerthattheyateupallthewildroses.Hehassolittletimethathecan’tgotothecinemawithyou.5.比较状语从句比较状语从句通常由as…as,比较级+than…等连词引导。例如:TomrunsfasterthanJohndoes.Thisclassroomisasbigasthatone.6.目的状语从句(1)目的状语从句通常由sothat,inorderthat引导。例如:Westartedearlysothatwecouldcatchthefirsttrain.Hestudieshardsothathecouldworkbetterinthefuture.Weusedthecomputerinorderthatwemightsavetime.(2)sothat既可引导目的状语从句,又可引导结果状语从句。区别这两种从句的办法有两个:1)目的状语从句里往往带有情态动词can,could,may,might等。2)从意思上看,目的状语从句往往表示的目的很明确。例如:Speakclearlysothattheymayunderstandyou.(目的状语从句)Jackisbadlyillsothathehastorest.(结果状语从句)7.让步状语从句(1)让步状语从句通常由although,though等连词引导。例如:Thoughheisyoung,heknowsalot.AlthoughIamtired,Imustgoonworking.(2)although(though)不能用在同一个句子中。例如:我们不能说:Thoughitwasraininghard,buthestillwentout.应该说:Thoughitwasraininghard,hestillwentout.或Itwasraininghard,buthestillwentout.第5页 济南新年华教育初中英语语法讲义第八讲8.地点状语从句地点状语从句常常由where来引导。例如:Gowhereyoulike.Wherethereisawill,thereisaway.【实例解析】1.(北京市海淀区试题)Youwillstayhealthy_______youdomoreexercise,suchasrunningandwalking.A.ifB.howC.beforeD.where答案:A。该题考查的是引导状语从句的从属连词的选择。从意思上看,从句应是一个条件状语从句,在这四个选项中只有if能引导条件状语从句,所以选A。2.(江西省试题)---Shallwegoonworking?---Yes,_________Iprefertohavearest.A.whenB.ifC.becauseD.though答案:D。该题考查的是引导状语从句的从属连词的选择。从意思上看,只有选though才能说得通。3.(徐州市试题)Noneofusknewwhathadhappened_________theytoldusaboutit.A.whenB.untilC.afterD.though答案:B。该题考查的是引导状语从句的从属连词选择。本句的意思是“在……以前我们没人知道这件事。”要表达着一意思应用“not…until”这一句型。4.(泉州市试题)---Ihopeyou’llenjoyyourtrip,dear!---Thankyou,mum.I’llgiveyouacall_________Igetthere.A.untilB.assoonasC.sinceD.till答案:B。该题考查的是引导状语从句的从属连词的选择。本题的意思是“一到那里,我就给你打电话。”要表达这个意思应选用assoonas。【演练】一.单项填空1._______he’sold,hecanstillcarrythisheavybag.A.ThoughB.SinceC.ForD.So2.---Doyouknowifhe_______toplaybasketballwithus?---Ithinkhewillcomeifhe______freetomorrow.A.comes;isB.comes;willbeC.willcome;isD.willcome;willbe3.Inthezooifachild_____intothewaterandcan’tswim,thedolphinsmaycomeup______him.A.willfall;tohelpB.falls;tohelpC.willfall;helpD.falls;helping4.Idon’tremember________heworkedinthatcitywhenhewasyoung.A.whatB.whichC.whereD.who5.Wewillstayathomeifmyaunt________tovisitus第5页
