Unit 6

一、单元语法

本单元的重点是状语从句，注意区别由when, while, till, until, since和before引导的时间状语从句及其用法。

1．基本构成形式：

时间状语从句通常是由when, while, before, after, as, since, till, until, as soon as 等从属连词引导。时间状语从句可以放在句首，也可以放在句尾。

2．表达意义：

时间状语从句的作用是用一个句子（从句）来作另一个句子（主句）的时间状语，表示主句中谓语动作发生的时间。

（1）由when引导时间状语从句时，从句用于表示主句动作发生的特定时间，从句中谓语动词为瞬间动作动词。若为延续性动词时，用while来引导。例如：The days get longer when spring comes.春天到来时，白天变得更长了。

Please send her my regards while you meet her.你见到她时，请代我问候她。（2）由before引导时间状语从句时，表示主句动作发生在从句动作之前。例如：

Close the door before you leave the room.离开房间前关上门。

（3）由until、till引导的时间状语从句。当主句谓语动词是延续性动词时，主句常用肯定形式；当主句谓语动词是非延续性动词时，主句要用否定形式，即not ... until / till ...（直到…才…）。till更多用于口语中。例如：

I’ll wait here until / till he comes back.我将在这里等着，直到他回来。

You can’t go home until / till you finish your work.直到你完成你的工作，你才能回家。

（4）由since引导的时间状语从句，since从句中要用一般过去时，主句中要用现在完成时。例如：

It has been three years since I last saw him.从我最后一次见他到现在已经三年了。
