在时间状语从句中,要注意时态一致。
1.when, while和as的用法(1) when, while和as的共同用法when, while和as都可以引导时间状语从句,意为“当......时候”。
若表示主何中的动词和从句中的动作同时发生,而从句的谓语动词是延续性动词时,这三个词是等同的,可以互换。
eg: When/While/As we were dancing, a stranger came in. 当我们跳舞的时候,一个陌生人进来了。
eg: When/While/As I was taking a bath, the telephone rang. 我在洗澡的时候,电话响了。
(2) when, while和as的用法区别①when引导的时间状语从句的谓语动词既可以是延续性的,也可以是非延续性的,而while引导的时间状语从句的谓语动词只能是延续性的。
eg: When you came in, I was talking with a few boys. 你进来时,我正在和几个男孩子谈话。
eg: While we were waiting for the bus, it was raining heavily. 我们等公交车时,天正下着大雨。
