as soon as 引导什么从句

2020-06-19 16:52:12文/董玉莹

as soon as意思是:一……就……;一经;不久后,一会儿。用法:可以引导时间状语从句,表过去,又可以表示将来。例句:As soon as he got inside, the dog shook himself.他一进来,狗就开始摇头摆尾。

as soon as 引导什么从句

as soon as 一……就……

1、指未发生的动作。时态规律是“主将从现”,即主句用一般将来时,从句用一般现在时代替一般将来时。

I’ll tell him the plan as soon as I see him.

我一看到他就告诉他这个计划。

He’ll go home as soon as he finishes his work.

他一完成工作就回家。

2、如果强调过去发生的两个动作有先后关系,从句谓语动词可以用过去完成时。例如:

As soon asthey(had)returnedfrom London,they drove to see their sick aunt.

他们一从伦敦回来,就开车去看望他们患病的姨妈。

3、hardly…when...它的意思是“几乎未来得及做完A这件事,紧接着就开始B这件事。”

使用这个短语时,一般用于过去完成时;并且when有时可改用before。例如: He had hardly finished the article when the light went out.他刚写完文,灯就熄了。

另外,如果把hardly放于句首,主句要用倒装结构即谓语动词要提前。如:Hardly had I finished eating when he came in.我刚吃完他就进来了。

这三个短语都有“一……就”、“刚刚……就”的意思,它们的意思非常相近,因此有时可以互换。例如:

“我刚到公共汽车站,汽车就开了。”一句,就可以有如下几句译法:As soon as I got to the bus stop,the bus started.Hardly had I got to the bus stop when the bus started.No sooner had I got to the bus stop than the bus started.

但他们之间也有一些差异,例如,如果从两件事情的间隔时间来说,as soon as较长,no sooner...than居中,hardly...when间隔时间最短。
