while

shelikescoffee.

(这里的while是等立连词不是从属连词，表示“然而，却”)Eg:1).Whenhecomeshereto222）.时间状语从句的中的till、until和not…until：肯定句:主句谓语动词必须是延续性动词,主从句都为肯定式,意为“某一动作一直延续到某时间点才停止”。Eg:Youmaystayhere

until/till

therainstops.Heremainedthereuntil/tillshearrived.否定句：主句谓语动词必须是非延续性动词,从句为肯定式，意为“某动作直到某时间才开始”。Eg:Hewill

no

ideaofwhattheyhadsaid.注意:till不可置于句首。2）.时间状语从句的中的till、until和not…unt233）.时间状语从句中before和since的用法：1)Beforehereturned,hismotherhadpreparedfoodforhim.(在…之前)2)Thefirelastedfourhoursbeforethefirefighterscouldcontrolit.(……才)3)BeforeIcouldspeaktohim,hehadlefthurriedly.

Bythetimehecomes,wewillalreadyhaveleft.例外：

Bythetimehewentabroad，hewasfourteen.(主句是系表形式或像know等表示”认知”的持续动词,则往往用一般时态。)4）.时间状语从句中Bythetime的用法：265）.原因状语从句中的because，since，as的区别。三者均表示“因为，由于”的意思。它们区别是：①because语气最强，用于回答why引导的有较强逻辑性的因果关系问题，它常常与only，just以及否定词not连用。Because引导的从句通常置于主句之后，只有在强调的时候在置于主句之前。例句：1）Tomshouldattendschoolbecausehehasreached7.2)Justbecausetheywantedtoearnmoremoney,theymadealotoflow-qualityproducts.5）.原因状语从句中的because，since，as的区别27②since和as语气都比较弱，多用在口语中，所表示的原因比较明显，或者是大家都已知的事实。因此，它们的前面不可用just，only等强调词和否定词not。它们引导的从句多置于句首。例句：1)Asyoualreadyknowthetruth,Ineednotexplainthewholethingtoyou.2)Sinceeveryoneishere,let’sbeginourmeeting,shallwe?②since和as语气都比较弱，多用在口语中，所表示的原因比28注意：for也是一个表示原因的连词，与because，since，as不同的是，它是个等立连词，放在句中连接两个并列的句子。For比较文气，长用于笔语。例句：Thedaysaregettingwarmerandwarmer,forspringiscoming.注意：for也是一个表示原因的连词，与because，sin29because,since,as,for1.Idancedinfrontofthepeople

Ihadnosecondchoice.because,since,as,for1.Idan306）.目的状语从句中的sothat和inorderthat:（为了。。。以便。。。）它们引导的状语从句中需要情态动词,inorderthat比sothat正式,引导的状语从句可置于主句之前或之后,而sothat引导的从句一般置于主句之后。Eg:1).Theysetoutearly

sothat(inorderthat)

theymightarrivethereintime.

2).

Inorderthat

wemightseethesunrise,westartedforthepeakearly.6）.目的状语从句中的sothat和inorderth31注意目的状语从句与不定式、介词短语的互换Eg:Theysetoutearly

sothat(inorderthat)

theymightarrivethereintime.=Theysetoutearly

inorderto(soasto)

arrivethereintime注意目的状语从句与不定式、介词短语的互换327）.结果状语从句中的so…that…和such…that…：Such+adj.+PL/+that-clauseSuch+a/an+adj.+n+that-clauseSuch+alotof/lotsof+PL+that-clauseso+adj./adv.+that-clauseso+adj.+a/an+n+that-clauseso+many/few+复数名词+that-clauseSo+much/little+不可数名词+that-clause7）.结果状语从句中的so…that…和such…that…33Eg:1.ItissogoodastorythatI’llneverforgetit.=ItissuchagoodstorythatI’llneverforgetit.Eg:1.Itissogoodastoryt348）.让步状语从句although和though的用法：Although与though意思相同,表示“尽管，虽然”的意思，一般可互换,都可以与yet,still或nevertheless连用,但不能和but连用。例句：Eg:1).Although(Though)heisold,heworkshard.=Heisold,butheworkshard.另外：though还可以用作副词，意为“可是，然而”，置于句尾。例句：Hesaidhewouldcome;hedidn’t,though.(可是)8）.让步状语从句although和though的用法：352.状语从句的时态问题：1）“主将从现”原则：一般情况下，时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”，用“现在完成时”表示“将来完成时”。例句：①IwillcallyouassoonasIarriveinBeijing.解说：这是由assoonas引导的时间状语从句，主将从现原则。2.状语从句的时态问题：36②AssoonasIhavefinishedthiswork,Iwillgohome.我一完成此工作，就回家。(解说：从句中的谓语动词用现在完成时havefinished，表示将来完成时,决不可用willhavefinished。)

③Ifyouworkharder,youwillpasstheexamnexttime.(主将从现)=Workhard,andyouwillpasstheexam.④I’llreturnthebookassoonasIhavefinishedreadingit.⑤He’llhavefouryearsatuniversityafterheleavesschool②AssoonasIhavefinishedth372）since与完成时：since引导时间状语从句时，其主句通常要用现在完成时，有时也用现在完成进行时。从句用一般过去时。例句：HehasgrownaninchsinceIsawhim.我上次见到他以后他已长高了一英寸。更多例句参看注：当主句为“It+be+一段时间”时，则通常用一般现在时代替现在完成时。如：It’smorethanthreeyearsnowsinceIsawherlast.我们已有三年多没见面了。

2）since与完成时：383）特定句式的时态：由nosooner...than,hardly/scarcely…when引出的时间状语从句，其主句通常用过去完成时，从句通常用一般过去时。另外：通常会把nosooner和hardly/scarcely提到句首时,这个时候应用部分倒装语序。（该知识点在倒装结构中有讲到，请参看！）3）特定句式的时态：39例句：Hardlyhadhearrivedwhenshestartedcomplaining.他刚到她就抱怨起来。Nosoonerhadhegonetosleepthanthetelephonerang.他刚睡着电话铃就响了。Wehadnosoonersetoutthanathunderstormbroke.我们刚出发就下起一阵雷暴。Nosoonerhadsheagreedtomarryhimthanshestartedtohaveterribledoubts.她刚同意嫁给他她就开始产生可怕的疑虑。例句：403.状语从句的倒装问题：
