时间状语从句

时间状语从句用来说明主句谓语动词发生的时间，一般由连词引导。时间状语从句常用以下连词引导：when，as，while，before，after，since，till/until，as soon as，the moment，hardly...when...，no sooner...than...，whenever，by the time等。

1. when，while，as都可表示“当……的时候”，但它们在用法上有区别：

①when强调“特定时间”，从句谓语动词可以是延续性或瞬时性的。

When he was eating his breakfast，he heard the doorbell ring. 吃早饭时，他听到门铃响了。

②while表示一段时间，从句谓语动词必须是延续性的，有时含有对比含义，意为“而，

1

然而”(表对比时为并列连词)。

While she was reading a novel，she fell asleep. 她看小说的时候睡着了。

While I was reading，he was playing. 我在读书，而他在玩。(强调对比含义) ③as多用于口语中，常表示两个动作同时发生，常译作“一边……一边……”。此外，还有“随着”之意。

She sang as she walked.她一边走一边唱。

As time goes by，we'll be older.随着时间的流逝，我们将会变老。
