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。

按照其意义,状语从句可分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句等。

二、时间状语从句1. 引导时间状语从句的从属连词很多,常见的有before, after, when, while, as, since, till, until, as soon as 等。
2. 表示“当…时候”的 while, when, as 的用法区别是:while从句中的谓语动词必须是延续性动词;表示带有规律性的“每当”或当主、从句谓语动词的动作发生有先后时,只能用 when;当表示“一边…一边…”或“随着”时,只能用 as。
