【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.

(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.

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.Youwillstayhealthy_______youdomoreexercise,suchasrunningandwalking.

A.if

B.how

C.before

D.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.---Shallwegoonworking?

---Yes,_________Iprefertohavearest.

A.when

B.if

C.because

D.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.Noneofusknewwhathadhappened_________

theytoldusaboutit.

A.when

B.until

C.after

D.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.---Ihopeyou’llenjoyyourtrip,dear!

---Thankyou,mum.I’llgiveyouacall_________Igetthere.

A.until

B.assoonas

C.since

D.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。第19讲:状语从句之考点精练一.单项填空
