反而时间状语从句。

结构为be doing sth. when 译为正在做某事时突然,此句型不再强调主句,反而强调了时间状语从句所表达的意思,因而叫做反而时间状语从句。

英语中when和while的用法区详细讲解

英语中when和while的用法区详细讲解

1.1 时间连词when的用法特点一般来讲,when的意思相当于at that time(在……时刻),因此从句的谓语动词通常是短暂动词,表示某一时刻的动作。

不过,when引导的从句也可接延续动词(continuous verb),这时从句往往用过去进行时态,表示某一时间段内发生的动作。

有关连词when常见的主从句时态搭配举例说明如下。

时间从句所表达的时间通常是过去和将来。

首先,来看when引导从句表示过去动作的四组时态搭配。

一、主句一般过去时+从句一般过去时1I started my dinner when he left. 他走了之后,我才开始吃晚饭。

2He left when I got there. 我到了以后,他才离开。

从以上例句可以看出,若主从句都用一般过去时,则表示从句动作先发生。

所以,从句还可以用过去完成时。

于是,就有了下面的第二种时态搭配关系。

二、主句一般过去时+从句过去完成时3I started my dinner when he had left.4He left when I had got there.这两句的从句用了过去完成时,更强调了从句动作先发生,意思与上面两句区别不大。

在表示过去的动作中,when引导的从句还有一个重要的时态搭配,即一般过去时(simple past)与过去进行时(past continuous)搭配。

注意,此时的时态搭配与主句、从句没有关系,而只与动作的长短有关系。

短暂动作用一般过去时,延续动作用过去进行时。

这一时态配套使用所表示的意义是:在一个延续背景动作的过程中突然发生了一个短暂动作。

既然此时的时态搭配与主从句没有关系,因此可以组合成下面两种时态搭配,即“主句过去进行时+从句一般过去时”,或“主句一般过去时+从句过去进行时”,即:1.主句一般过去时+从句过去进行时5The doorbell rang when I was telephoning.妙语点睛这里的短暂动作rang用一般过去时,延续动作telephone用过去进行时。
