7、 the whole morning.Step3 Grammar2 when, while, as 都有“当的时候” 。1. while 指一段时间，它所引导的从句中的谓语动词必须是延续的，不可以是瞬间性的动词，如：判断正误While he reached there，They were playing basketball. ( )While I was waiting for a bus, I met my cousin. ( )注意：（1）当强调两个延续性的动作同时发生时，常用“过去进行时+while+过去进行时”e.g. 当他在打电话的时候，我在写信。I _ _ a letter _
8、he _ _ a phone call.- 2 -(While he _ _ a phone call, I _ _ a letter.)（2）当强调某个动作发生时，另一个动作正在进行，用“一般过去时+while+过去进行时”e.g. 我们正在读书的时候，老师走了进来。The teacher _ in _ we _ _.我妈妈在睡觉的时候，电话铃响了。While my mother _ _, the telephone _.while 的使用特点也可以记忆为：while 后面不接一般过去时(即短暂性动词) 。2. when 和 as 使用范围比 while 广泛，它们引导的从句中的谓语动词既可
9、以是延续性的，也可以是短暂性的。换言之，能使用 while 的句子也可以使用 when 或 as 替代，如“一般过去时+while/when/as+过去进行时”、 “过去进行时+while/when/as+过去进行时” 都可以。注意：when 和 as 的特殊之处：when 引导的从句中的谓语动词可以在主句的动词之前、之后发生。When he finished his homework, he played the computer games for a while.(when 相当于 after，finish 先发生)When I got to the park, the gate was
10、 closed.(when 相当于 before， get to 后发生)When 引导的从句含有突然发生的意思：我在街上散步，他突然喊我。I _ _ in the street when he called me.as 可理解为“随着”随着日子变短，温度开始下降。_ the days are shorter, the _ starts to drop.随着时间推移，中国日渐富强。_ time goes by, China is getting richer and stronger.Step4 Exercises【课后巩固】一、词汇A) 根据句意用所给中文或音标的正确形式完成句子1.
