4、off the exercises on the sheet. 【语法小贴士】 1. 使用before, after, when和while (1) 我们用连词before, after, when和while引导时间状语从句。before表示早于某个特定时间；after表示晚于某个特定的时间。(2) when表示“当.时”，表示主句动作发生的特定时间；while也表示“当.时”，强调主句动作和从句动作是同时发生的。 e.g. I was ready to go to bed _ my father came back from work. （when/while） I met Peter _
5、 I was waiting at the bus stop.（when/while）2. 使用since, till 和until since,till和until也可用来引导时间状语从句。since表示自从某个特定的时间（开始）。主句中的动词经常用现在完成时。till 和until 都表示直到某个特定的时间，通常可以互换，但是till 比until更不正式。注意： 如果主句中的谓语动词是瞬间动词，该动词用否定形式，形成“not .till /until”结构，意思是“直到.才（开始）”。e.g. 昨天我做完作业才上床睡觉。I _ go to bed _ I finished my home
6、work yesterday.3. 使用as soon as 和whenever. as soon as 意思是“一.就” e.g. 他一到那就会给你打电话。He _ _you as soon as he _ there. 你作业一做好就可以休息一下。 As soon as your homework _ _ , you can have a rest.whenever 意思是“每当；任何时候”e.g. 每当她有时间的时候，他就喜欢听音乐He likes listening to music _ he has time. 【课堂巩固】一、词汇运用。1.
