  24. 语法小结 时间状语从句 在句子中作时间状语的从句叫做时间状语从句。一般情况下，时间状语从句可以位于主句之前或主句之后，位于主句之前时，通常用逗号与主句分开。引导时间状语从句的从属连词有很多，现将它们的用法作一详细介绍：

  25. 1. when / while引导的时间状语从句 when和while都可意为“当……的时候”。 when引导的时间状语从句既可以表示点时 间，也可以表示时间的延续，即表示一段时 间，因此从句的谓语动词既可以是瞬间动 词，也可以是延续性动词。此外，从句的动 作既可与主句的动作同时发生，也可先后发 生。如： I will tell you about that thing when I meet you. When I see the photo, I can’t help thinking of Paul.

  26. while引导的时间状语从句表示时间的延续，即表示一段时间，而不是瞬间，因此从句的谓语动词不能是瞬间动词。此外，主句的动作发生在从句所表示的时间段之内或主从句动作同时发生。如：while引导的时间状语从句表示时间的延续，即表示一段时间，而不是瞬间，因此从句的谓语动词不能是瞬间动词。此外，主句的动作发生在从句所表示的时间段之内或主从句动作同时发生。如： Jenny went to the movies while I was having a class. Mum was preparing for dinner while I was cleaning the room.

  27. 2. before / after引导的时间状语从句 before引导时间状语从句时表示主句的动作 发生在从句动作之前， after引导时间状语 从句时表示主句的动作发生在从句动作之 后。如： Write it down before you forget. I will call you after I hear from him.

  28. 3. till和 until的意义和用法相同，一般可以换用 (放在句首时通常用until，till在口语中更为常 见)。二者引导时间状语从句，表示主句谓语 动词所表示的动作持续到从句谓语动词所表 示的动作发生为止。not ... till / until ... 表示 “直到……才(开始)”， 例如： Walk till you come to a white house. Mike didn’t announce the news until he was sure of it.

  29. 4. since引导的时间状语从句 since意为“自从；自……以来”，多数情况下 主句用完成时，从句用一般过去时。如： Miss Li has lived in Shanghai since she came to China.

  30. 5. as soon as引导的时间状语从句 as soon as意为“一……就……”，强调主句 的动作紧跟着从句的动作发生。如果主句 是一般将来时，as soon as引导的时间状语 从句要用一般现在时表示将来。如： I’ll send you an email as soon as I get there.

  31. 6. whenever 意思是“每当；任何时候”。如： He likes listening to music whenever he has time. 注意：whenever 可以用every time替换。

  32. 注意： 在含有时间状语从句的主从复合句中，主句和从句的时态一般要根据具体情况来确定，但如果主句和从句都表示将要发生的动作时，通常主句用一般将来时，从句用一般现在时。如： I will call you when I get home. I will tell you as soon as I get the news. John’s mother won’t believe him until he tells her the truth
