首先我们要弄清楚什么是状语。

状语在句子中主要是用来表示动作发生的时间、地点、方式、原因、目的、结果、伴随、比较、条件、让步等关系。

此外,状语也可以对形容词或整个句子进行修饰,表示程度等。

状语从句多由从属连词引导。

第一节时间状语从句概述:时间状语从句表示主句谓语动词所表示的行为发生的时间,通常由以下各从属连词引导:when、whenever、while、as、before、after、since、till、until、as soon as the moment、once、hardly…when、no sooner… than、scarcely…when(一……就)等下面就各个连词的用法简单解释一下。

1.when、whenever引导一般可表示:主、从句谓语行为可同时发生,也可有先后。

当when,whenever在句首时,从句后有时会有逗号。

不过when也有出现在句中的时候,此时,when往往译为“这时”。

如:(1) When I got home, my brother had went out. 当我到家时,哥哥已经出去了。

此句中,主从句谓语行为发生有先后。

(2) When they are planting trees, they found a new cave.他们在植树时,发现了一个新的山洞。

(表示主、从句谓语行为同时发生)(3) Whenever she comes to our city, she always phones me.无论什么时候她来到我们市,她总是给我打电话。

2.while引导:主句谓语行为发生在从句谓语的过程中,或主、从句行为同时发生。

while一般可以译为“当……时候;与此同时;然而”。

(1) I am listening to the music while my son is doing his homework.我在听音乐,儿子在做作业。
