三大从句总结

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.

总结:
