状语从句
i、时间状语从句
一、when,while和as
1. when既可引导一个持续动作,也可引导一个短暂动作,可用于主句和从句动作同时发生或从句动作先于主句动作。如:
when i lived there, i used to go to the seashore on sundays.我住在那里时,星期天常到海滨去。
when the film ended, the people went back. 电影一结束,看电影的人便回去了。
当when引导的时间状语从句为系表结构,而且其主语和主句的主语一致,其表语又是一个名词时,就可以用以as引出的省略句,来代替when引出的从句。as a you man (=when he was a young man),he was fond of hunting。他年轻时,喜欢打猎。
2.while引导的动作必须是持续的,侧重主句动作和从句动作相对比。如:
please don’t talk so loud while others are working 别人在工作时,别高声谈话。
while i was wondering at this, our schoolmaster took his place. 正当我对此不解时,我们校长就座了。
