知识过关第8讲 语法二
时间状语从句
在复合句中，由时间连接词引导的状语从句叫做时间状语从句。时间状语从句通常由when, while,as, after, before, since, until, as soon as等词引导。
一、 when、while和as的用法与区别
三者都表示“当……时候”，需要注意的是：
1. when引导的时间状语从句中，用动词的一般现在时表将来。
Mr. Smith will call you up when he arrives in Beijing.
当史密斯先生到达北京时，他将给你打电话。
2. when也能表示“正在这时”。
I was walking in the park, when it began to rain.
我正在公园里散步，这时天开始下雨了。
3. 与进行时连用时，when相当于while或as。
When/While/ As Jane was playing the violin, I walked in quietly.
当简在拉小提琴时，我悄 悄地走进了。
4. as引导时间状语从句时表示“当……时；一边……一边……”，侧重表示两个动作同时发生。
The boy jumps as he goes along.
那个男孩边走边跳。
由before和after引导的时间状语从句用法
1、Before当主句用将来时，从句总是用现在时；如果before引导的从句谓语用的是过去时，则主句动词多用过去完成时，这样以便体现动作发生的先后。
It will be four days before they come back.
他们要过四天才能回来。
2、After表示主句动作发生在从句动作之后。从句是过去完成时，主句是一般过去时。
After you think it over， please let me know what you decide.
你仔细考虑过以后，告诉我你是怎样决定的。
after表示主句动作发生在从句动作之后。
After you think it over, please let me know what you decide.
你仔细考虑过以后，告诉我你是怎样决定的。
三、as soon as引导的时间状语从句用法
as soon as意为“一……就”，表将来要发生的动作，遵循“主将从现”的原则；表示两个紧接着发生的动作，主从句都用一般过去时。
As soon as she comes to the party, we will give her a big surprise.
她一来参加晚会，我们就给她一个大惊喜。（现在）
As soon as he got to the station, the train left.
他一到达火车站，火车就离开了。(过去)
四、until引导的时间状语从句用法
1. 在含有until引导的时间状语从句中，如果主句的谓语动词是延续性动词，如：work，live，stay，study，play，wait等，那么这个主句常用肯定式，表示动作一直延续到until所表示的时间为止。until可意为“直到……为止”。
I’ll work until he tells me to stop.
我会一直工作到他叫我停下来为止。
2. 在含有until引导的时间状语从句中，如果主句的谓语动词是非持续性动词，如：come，go，leave，begin，start，finish等，那么这个主句常要用否定式，表示某一动作到until所表示的时间才发生。即not ...until... 意为“直到……才……”。如：
She didn’t go to bed until she finished her homework.
直到做完作业， 她才去睡觉。
