时间状语从句
一、什么是时间状语从句:当我们用一个句子表达一件事情发生的时间时,这个句子叫做时间状语从句。

(was reading是延续性的动词,was reading和was watching同时进行)② While we were having a meeting, Mr. Black came in.正当我们开会时,布莱克先生进来了。
(were having a meeting 是延续性动词,该动作正在进行时,另一个动作发生)2)学会使用before 与 afterbefore 表示“在…之前”; after 表示“在…之后”Eg: My father had left for Canada just before the letter arrived.我父亲恰好在信到之前去加拿大了。
Eg: After we finished the work, we went home.完成工作之后,我们回家了。
