英语中的九大状语从句状语从句在主从复合句中修饰主句中的动词、形容词或副词等，按意义可以分为时间、地点、原因、目的、结果、条件、方式、比较、让步等状语从句。
一．时间状语从句。
通常由从属连词when, whenever, as, while, before, after, as soon as, till, until, since, once (一旦), hardly……when…, no sooner…….than…; 等引导。
例如：The cyclist started just as the lights changed to green.Whenever we met with difficulties , they cam to help us.He didn’t leave his office until he had finished the day’s work.应注意的问题1．在时间状语从句中，通常要用动词的一般现在时态表示一般将来时态，用一般过去时态表示过去将来时态。
但when 引导一般疑问句或名词性从句时不受上述语法规则的限制，因此，应该加以区分。
例如：When China will enter WTO depends on the bilateral (双边的)joint efforts.Once you understand the rules of the game, you’ll enjoy it.2.when , while, as 的不同用法。
一般说来，当主、从句的动作是同时发生的事，三者可以换用。
when 既可以引导一个持续动作，也可以引导一个短暂动作，可用于主句和从句动作同时发生或从句动作先于主句动作；while 引导的动作必须是持续性的，强调主句和从句的动作同时发生，往往侧重主句和从句动作的对比；as 用于引导“在某行为的继续中发生某事”的“继续之行为”，所以多与过去进行时连用，翻译成“一边……一边……”或者表示动作的变化，翻译成“随着……”。
