过去进行时 · PET / B1
天天向上 · 原创语法学习讲义
用 B1 故事语境区分背景、同时进行和新发生的事件；不把 when / while 当成固定的时态按钮。
背景与事件
过去进行时像把镜头放进动作中间；一般过去时把事件作为一个整体来讲。
We were waiting for the bus when it began to snow.
开始下雪时，我们正在等公交。
“另一事件发生”不一定意味着原动作停止，除非后文明确说明。
语序与主语
was / were 跟主语匹配，后接 -ing；问题和否定保留这套结构。
What were you doing while the others were setting up the tent?
其他人在搭帐篷时，你在做什么？
you 用 were；不要因为中文“你”是一个人就用 was。
同时进行与先后发生
when 和 while 都需要结合动作关系理解；while 常引出持续背景或两个同时进行的动作。
While we were packing, Dad was checking the weather.
我们收拾行李时，爸爸正在查看天气。
如果要说先完成一件事再做另一件事，after / then 往往更清楚。
时间长度不能机械决定时态
一段时间可以用进行时突出过程；已结束的完整事件也可用一般过去时。
I was revising all evening, so I did not check my messages.
我整晚都在复习，所以没有查看消息。
不要把所有“长动作”一律判成进行时。说话人怎样呈现事件同样重要。

表达任务
以“I was on my way to…”开头，用 70–100 词写一个小故事。包括一个进行中的背景、一个突然发生的事件，以及后续结果。
□ 背景与新事件的时态有区别。
□ when / while 后的结构完整。
□ 故事有后续结果，没有把每个过去动作都写成进行时。
参考表达
I was on my way to the sports centre when I noticed a little dog outside a shop. It was shaking, and nobody was looking after it. While I was checking its collar, the shop assistant came outside. She recognised the dog and called its owner. We waited together until he arrived. I was late for training, but I was glad the dog was safe.
