语法：
Past continuous tense 过去进行时
1. 过去进行时的含义
(1) 在过去某一时刻正在进行的动作或发生的事(不强调是否完成)。如：
My mother was making cakes at 9：00 last night. 昨晚九点我妈妈在做蛋糕。
(2) 在过去某一阶段一直在进行的动作。如：
From 1980 to 1995, she was teaching in a school.
从1980年到1995年，她在一所学校教学。
2. 过去进行时的句式和过去进行时的基本结构
肯定句用“was/were ＋现在分词”；否定句在was/were后面加上not,即:was/were not ＋现在分词；疑问句将was/were调至主语前面。如：
— Were you singing at that time 那时候你在唱歌吗？
— Yes, I was./No, I wasn't.是的，我在。/不，我不在。
Grammar parts：
△过去进行时
考 点
was / were + doing　
过去进行时的时间状语:

结构:
(1)the whole morning (2)at this/that time yesterday
(3)at 8:00 yesterday night (4)from 6 to 8 last night (5)when (6)while
(7) 根据情景
过去进行时强调正在，不知道是否结束，
而一般过去时表示已完成的事情。
while 引导的从句中谓语动词必须用延续性动词,强调两个动作同时进行,常用于进行时态。
when 引导的从句中谓语动词可以是延续性动词,也可以是短暂性动词,主句与从句的动作可同时发生,也可先后发生。
as 引导的从句中谓语动词可以是延续性动词,也可以是短暂性动词,强调两个动作同时进行,表示“一边……一边……;随着……”。
while/when/as的用法
e.g.I was watching TV while my mother was cooking in the kitchen.
当我妈妈在厨房做饭时，我在看电视。
e.g. They were talking noisily when Mr. Wang walked in.
当王先生走进来时，他们正喧闹地谈论着。
e.g. As she grew older, she gained in confidence.
随着年龄的增长，她的自信心增强了。
1.while/when/as这三个词均有“当……时候”的意思。
2.
*强调两个动作同时进行，常用“一般过去时+while+过去进行时”结构。
*强调某个动作正在进行，另一个动作突然发生，常用“过去进行时+when+一般过去时”结构。
