為您解答
用表示時間的連詞連接一個句子作狀語，這樣的主從復合句就是時間狀語從句。
①when
when引導時間狀語時,表示主句謂語動詞的動作與從句謂語動詞的動作是同時發生的,或者從句的動作發生在主句的動作之前的?？杀硎尽耙欢巍睍r間或“一點”時間。
例:She was taking a walk when I called her.
我叫她時,她正在散步。
②while
while引導時間狀語從句強調主句的動作和從句的動作在某一時間內同時發生,意為“在……期間,在……過程中”。while引導的時間狀語從句只能表示一段時間(同延續性動詞連用),不能表示一點時間(不可同非延續性動詞連用)。
例:While she was watching,she heard the bell ring.
她正在看電視時聽到了門鈴響。
③as
as引導的時間狀語從句表示“當……時,一邊……一邊”,指主句的動作和從句的動作同時發生,既可以表示一段時間(同延續性動詞連用),也可以表示一點時間(同非延續性動詞連用)。
例:I saw her as she was getting off the bus.
她下汽車時我看見了她。
英語狀語從句分8種：
1.時間狀語從句（adverbial clauses of time）,多由連詞引起。
（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).
少數不由連詞引起狀語從句。
（now that,every time,each time,the moment,immediately,instantly,directly）
E.g. Directly he uttered(vt. 說出)these words, there eas a dead silence.
I had no sooner checked in the hotel than he arrived.
2.地點狀語從句（adverbial clause of place）
(where,wherever,anywhere)
E.g. The church was built where there had once been a roman temple(n.寺廟).
Everywhere I go, I find the same thing.
3.方式狀語從句（adverbial clause of manner）,一般由as，like，as if引起。
英語狀語從句的九種類型有時間狀語從句、地點狀語從句、原因狀語從句、目的狀活從句、結果狀語從句等。
1、時間狀語從句。
常用引導詞：when，as，while，as soon as， before，after，since，till，untill.

狀語從句主要用來修飾主句或主句的謂語。一般可分為九大類，分別表示時間、地點、原因、目的、結果、條件、讓步、比較和方式。盡管種類較多，但由于狀語從句與漢語結構和用法相似，所以理解和掌握它并不難。狀語從句的關鍵是要掌握引導不同狀語從句的常用連接詞和特殊的連接詞即考點。 現分別列舉如下:
