Adverb Clauses of Time(时间状语从句)用来修饰谓语动词、其他动词、定语、状 语或整个句子的从句叫状语从句。状语从句 有很多种，今天我们主要学习由when, while, before, after, as soon as, since, until引导的时 间状语从句。

◆when从句的动作可与主句的动作同时发生，也 可先于主句的动作；从句的谓语动词可以是延续 性动词，也可以是瞬间性动词。并且when有时意 为“就在那时”。如： When I got home, he was watching TV. 当我到家的时候，他正在看电视。 Mozart started writing music when he was four years old.当莫扎特四岁的时候，开始写音乐作品。 I was about to go out when the telephone rang. 我刚要出门，电话铃响了。

◆while只能指一段时间，而不能指时间点。从 句的动作或与主句的动作同时发生，或主句的 动作是在从句动作的过程中发生的。因此，从 句中的动词必须是表示延续性动作或状态的动 词。如： While I was sleeping, my brother came in. 当我在睡觉的时候，我弟弟进来了。 He visited a lot of places while he was traveling. 他在旅途中参观了许多地方。

when和while 的区别when与while 都意为“当……的时候”。 when 引导的时间状语从句, 谓语动词既可 以是持续性的, 也可以是终止性的；而while 引导的时间状语从句, 谓语动词只能是持续 性的, 并且常用进行时态。试比较：

When he woke up, it was eight o’clock.√ While he woke up, it was eight o’clock.× When I was waiting for a bus, I met her.√ While I was waiting for a bus, I met her.√

◆before表示主句的动作发生在从句之前。 如: I won’

t tell you the truth before he comes back. 他回来之前我是不会告诉你事实的。 ◆after表示主句的动作发生在从句的动作之 后。如： After she finished the work, she went to have supper. 她完成工作后去吃晚饭了。

◆as soon as表示主句的动作紧随从句动作之后 发生的。表示“一……就”。如： I will call you as soon as I arrive home.

我一到家就给你打电话。I hope to find him as soon as possible.

我希望尽可能快地找到他。Mother became unhappy as soon as I mentioned his name. 我一提到他的名字，母亲就变得很不开心。

◆until(till)在肯定句中，常与延续性动词 连用，意为“到……为止”;在否定句中，常 与表示瞬间性动作的动词连用，意为“直到 ……才”,这时till 和until可以与before 替换 。如： Last night I waited until eleven o’clock, but he didn’t return. 昨天晚上我一直等到11点, 但他还没回来。 My son won’t come home until it is dark. 我儿子不到天黑不回家。

◆ since可引导时间状语从句， 意思是“自从 … 的时候起；从此；从 … 以来； … 以后” 等。 1) 若since引导的状语从句的谓语动词是终止 性动词(如go, come, leave, start, begin等)的过 去时, 则从句表示的时间是“从该动作开始的 那一时刻起”。这是最常见的一种用法。如： He has studied very hard since he came to our school. 自从来到我们学校， 他学习就非常努力。

2) 若since引导的状语从句的谓语动词是持续 性动词或表示状态的静态动词(如live, stay, study, learn, smoke, be等)的过去时, 则从句表 示的时间是“从该动作或状态的完成或结束时 算起”。如： I haven’t heard from him since he lived here. 从他不住这儿起， 我一直没有收到他的信。 I haven’t eaten snakes since I was a student at school. =I haven’t eaten snakes since I left school. 自从我毕业后就一直没吃过蛇。
