注意:当no sooner...than...,hardly...when...中的no sooner,hardly置于句首时,主句部分用倒装语序。

5.名词短语充当连词引导时间状语从句
常见的此类短语有:the moment,the minute,the instant,the first,the first(second...last) time,last time,next time,any time,each time,every time,by the time等。
Each time he came to Harbin,he would call on me.
他每次来哈尔滨,总会来看我。
注意:当by the time引导时间状语从句时,在一般情况下,如果从句的谓语动词用一般过去时,则主句的谓语动词用现在完成时;如果从句的谓语动词用一般现在时,则主句的谓语动词用现在完成时。
二、原因状语从句
引导原因状语从句常用的连词有:because,since,as,now that等。
1.because表因果关系的语气最强,常用来回答why的提问,所引出的原因往往是听话人不知道或最感兴趣的。because引导的原因状语从句往往比主句显得更重要。
I'm leaving because I am fed up with the boss.
我离开是因为我讨厌老板。
2.since表示众所周知的原因,故常译成"既然......",通常放在句首。since引导的从句是次要的,重点强调主句的内容。
Since everybody is here,let's begin!
