初中英语状语从句讲解、练习与答案

2013年英语竞赛辅导：状语从句状语从句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：Itwasraininghard（rainhard下大雨）whengottoschoolyesterday.Whilehewasdoinghishomework,thetelephonerang.Ashewalkedalong（沿着走）thelake,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（熄灭）.Let’swaituntiltherainstops.Wewon’tstartuntilBobcomes.Don’tgetoff（从下来）untilthebusstops.【Till是指直到某一特定事件发生的时候，而在那个时刻之后，该事情或状况仍将持续。Until是指直到某一特定事件发生的时候，而讲话的人在自己心里认为，在那个时刻之后，该事情或该状况将中止（不怎么可能持续）。固定组合里frommorningtillnight，till/until是不能替换的，】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,weshallnot（不得；不应该）gothezoo.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.Motherlivessofarawaythatwehardlyever（几乎不，从来不）seeher.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.（天花板）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’tgotothecinema（去看电影）withyou.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（为了，以便）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)Jackisbadlyillsothathehastorest.(结果)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.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.总结：状语从句分类及常用连词：
