状语从句状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。

状语从句1. 时间状语从句常见的连词(组)：when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。

可以引导时间状语从句的副（介）词（短语）或名词短语：directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。

注意点如下：(1) when, while, as引导的时间状语从句as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。

when(at or during the time)既可以表示在某一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。

while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a period of time时，两者可以互换。

She came up as I was cooking.(同时)在我做饭时，她走了过来。

When we were at school, we went to the library every day.(在一段时间内)当我们在学校时，每天都去图书馆。

While they were watching TV, I was preparing myself for the coming examination.他们在看电视，而我在为即将到来的考试做准备。

2）while
while侧重主句的动作发生在从句的时间之间，且从句的动 词必须是持续性的。 while+持续性动词 While we were chatting ,she was looking at the time table on the wall． While I slept, a thief broke in.
3）as
as表示 一边…一边…，强调从句和主句中两个动作交 替进行或同步进行。 Sometimes I watch TV as I am having breakfast．（一边...一边...） as表示随着，此用法不用when或while替 As spring warms the earth, all flowers begin to bloom. （随着）
