专题02 过去进行时
过去进行时
1.【过去进行时的含义（用法）】
① 表示过去某一时刻正在进行或发生的动作。
② 表示过去某一段时间内一直在做或持续进行的动作。
③ 在复合句中，若主要动作和背景动作是同时发生的，那么主从句都可用过去进行时。
如：Mary was doing some reading while her younger brother was writing. 玛丽在看书，此时，她弟弟在写字。
④ 表示从过去某一时间看来将要发生的动作（趋势），尤其是come, go, leave, start, begin, move等表示位置移动和起止的动词。
如：She told me she was leaving for Beijing next week. 她告诉我她下周动身去北京。
⑤ 与现在进行时相似，过去进行时也通常与 always, forever等副词连用，表示满意、称赞、惊讶、厌恶等感情色彩。
如：The boy was continually asking questions. 这孩子总是问东问西的。
2.【谓语构成】
由“助动词be的过去形式（was/were）+v-ing”构成。

- My mother ______ dinner at seven last night.
- cook B. cooks C. was cooking D. were cooking
- —What ______ you ______ at 8 o’clock yesterday morning?

2.We ______ a movie from 7 to 9 last night.
- see B. saw C. was seeing D. were seeing
3.She ______ a letter when I came in.

3.【过去进行时常见的时间状语】
① 过去进行时常与过去某一特定时间状语连用。常见的时间状语有：last night, at that time, at noon yesterday, last Sunday等。
② 也有时在没有时间状语的情况下，需要通过上下文的暗示或者在同一个句子中的推理来判定用过去进行时。
如：At that time, we all knew what we were studying for. 那时，我们都知道为什么而学习。
基础题：
- They were playing football ______ yesterday afternoon.
A. at that time B. next time C. every day D. now
2.—What were you doing ______?
—I was having a math class at that moment.
- tomorrow B. at this time yesterday
C. every morning D. right now
4.【when和while的区别】
（一）核心本质
when：既可接短暂动作，也可接延续动作；从句动词可短暂 / 可持续
while：只接延续动作；从句动词必须是进行时 / 延续性动词
简单一句话：短暂动作只用 when；两个长动作同时发生多用 while。
（二）分场景详解
从句是短暂动作（瞬间完成：arrive, meet, knock, buy, see）→ 只能用 when
When I arrived home, my mom was cooking. 我到家时，妈妈正在做饭。 （到家是一瞬间，不能用 while）
从句是延续动作（长动作，常配进行时）→ when /while 都可以
When/While she was reading, I was watching TV. 她看书的时候，我在看电视。

主从句两个动作同时持续进行，强调对比 → 优先 while
While my sister was sleeping, I was doing homework. 妹妹睡觉的时候，我在写作业。
表示 “然而、对比”（转折）→ 只能 while
Some people like coffee, while others prefer tea. 有些人喜欢咖啡，然而另一些人偏爱茶。
主句先结束，从句动作正在进行；或突然发生某事 → when
I was walking when a dog ran out. 我正在走路，突然冲出来一条狗。
when可作特殊疑问词，对时间进行提问；while 不能。
When were you born? 你是什么时候出生的？
时态搭配规律：
when从句一般过去时（短动作）+ 主句过去进行时
while从句一定过去进行时（长动作）
做题技巧：
从句动词一瞬间完成（ring/arrive/meet/lose）→ 只用 when
从句是过去进行时（was/were doing） → when/while 都能用
前后句子对比、然而 → 只能 while
两个动作同时持续进行，突出同步 → 优先 while
