... when/as/while ...

结构︰

主要子句+when/as/while+子句

说明︰

此句型意为“当…时”。when 引导的<子句>,不仅说明一般时间,而且可以表示与<主要子句>同时或提前的动作时间。两个<动词>常用现在式。as 所表示的同时意义更突出一些,语意更强一些;while 多指动作的过程,时间范围较大一些。<连接词> while 后面的<主语>,如果与<主要子句>的<主语>相同时,while 后面的<主语>与 be <动词>可以省略,如例句8。

While she was reading in the room (=While reading in the room), she heard John call her.
