1 人教版八年级下册过去进行时 ● 语法讲解 1.构成: was/were+doing 2.用法: 过去进行时主要表示过去某一时间或某一段时间正在进行的动作
如: His father fell and hurt himself while he was riding his bicycle
他爸爸骑自行车时摔了下来,受伤了
3.常用时间状语: this morning, the whole morning, all day, yesterday, from nine to ten, last morning, when, while 等
4.when 与 while 的区别 (1)引导时间状语从句时,while 连接的是时间段,而 when 连接的多是时间点
如: What was your father doing while your mother was cooking
你妈妈做饭时,你爸爸在干什么呢
What was your mother doing when you came back
当你回来时,你妈妈在干什么呢
(2)while 可以连接两个并列的句子,而 when 不可以
如: I was trying my best to finish my homework while my sister was watching TV
我当时正在尽力完成作业,而我妹妹正在看电视
(3)when 是特殊疑问词,可以对时间进行提问,而 while 不能
如: When were you born
你什么时候出生的
过去进行时练习 一、用动词的适当形式填空
I ___________ (have) my breakfast at half past six yesterday morning
