用表示时间的连词连接一个句子作状语，这样的主从复合句就是时间状语从句。
①when
when引导时间状语时,表示主句谓语动词的动作与从句谓语动词的动作是同时发生的,或者从句的动作发生在主句的动作之前的。可表示“一段”时间或“一点”时间。
例:She was taking a walk when I called her.
我叫她时,她正在散步。
②while
while引导时间状语从句强调主句的动作和从句的动作在某一时间内同时发生,意为“在……期间,在……过程中”。while引导的时间状语从句只能表示一段时间(同延续性动词连用),不能表示一点时间(不可同非延续性动词连用)。
例:While she was watching,she heard the bell ring.
她正在看电视时听到了门铃响。
③as
as引导的时间状语从句表示“当……时,一边……一边”,指主句的动作和从句的动作同时发生,既可以表示一段时间(同延续性动词连用),也可以表示一点时间(同非延续性动词连用)。
例:I saw her as she was getting off the bus.
她下汽车时我看见了她。
英语状语从句分8种：
1.时间状语从句（adverbial clauses of time）,多由连词引起。
（when,after,before,as,as soon as,as long as,since,whenever,once）
E.g. When we lived in town we often went to the theater.
It was a long time before I got to sleep again.
As the sun rose the fog dispersed(vt. 消散).
少数不由连词引起状语从句。
（now that,every time,each time,the moment,immediately,instantly,directly）
E.g. Directly he uttered(vt. 说出)these words, there eas a dead silence.
I had no sooner checked in the hotel than he arrived.
2.地点状语从句（adverbial clause of place）
(where,wherever,anywhere)
E.g. The church was built where there had once been a roman temple(n.寺庙).
Everywhere I go, I find the same thing.
3.方式状语从句（adverbial clause of manner）,一般由as，like，as if引起。
英语状语从句的九种类型有时间状语从句、地点状语从句、原因状语从句、目的状活从句、结果状语从句等。
