定义
在句子中起状语作用的从句叫作状语从句 。状语从句可位于主句前（通常用逗号与 主句隔开），也可位于主句之后（不需用 逗号隔开）。 状语从句可表示时间、地点 、原因、条件、让步、方式、比较、目的和 结果等。

意义
状语从句(一)
状语从句（一）1. 时间状语从句：1) 由as, while引导时，表示主句和从句的动作同时发生，或一个动作在另一个动作或状态的过程中;2) 由after, when引导时，表示主句动作在从句动作之后;例：1995年1月四级第58题Michael used to look hurt and surprised when ________.A) scolding B) to scold C) having scolded D) scolded本题从句主语与主句主语全都，这种状况下，状语从句的主语时常省略，这是要留意状语从句中的谓语动词应用现在分词还是过去分词。
全句的意思是：麦克尔过去受到责难时，看起来又难过又惊异。
麦克尔是被责难，因而应当用过去分词，所以答案是D。
3) 由before, when引导时，表示主句动作发生在从句动作之前;例：1997年6月四级第44题I had just started back for the house to change my clothes ______ I heard voices.A) as B) when C) after D) whole本题前半部分的意思是：我刚动身回屋换衣服，后半部分的意思是：我听到有人说话。
前半部分用过去完成式，后半部分用一般过去时。
前半部分的动作发生在后半部分之前。
为表达这一情景，前半部分作主句，主句中一般用just，hardly，后半部分作从句，用连接词when引出。
答案是B。
when从句可能表示多种意义，这里它表示一种原来没有预料到的新状况消失。
又是这一新状况打断了主句表示的正在进行的活动，或制止了即将发生的状况。
在这种状况下，主句常用进行式、完成式或be about +inf.之类。
我们来看下面的例题：例：1996年1月四级第45题I felt somewhat disappointed and was about to leave ______ something occurred which attracted my attention.A) unless B) until C) when D) while全句的意思是：我感到有些绝望，刚要离开时，发生了一件事，吸引了我的留意力。
