说出当时正在发生什么
能说出过去某个时刻正在发生什么,以及是什么打断了这个过程。
标注的核心时长。核心模块中有两项未标注时长,因此实际课时比总和更长。
语法
4 分钟was / were + 带 -ing 的动词(过去进行时)——过去某个时刻正在进行的动作。
| At seven o'clock I was working. | 七点的时候我正在工作。 |
| They were walking in the park. | 他们正在公园里散步。 |
| Were you sleeping? | 你那时在睡觉吗? |
| I wasn't listening. | 我当时没在听。 |
里面都是学过的东西:A1 第27课的 was/were 和 A1 第25课的 -ing 形式。
两种过去时态成对使用,这是本课的重点:
| 长动作——背景(Past Continuous,过去进行时) | 短动作——事件(Past Simple,一般过去时) |
|---|---|
| I was walking in the park | when it started to rain. |
| She was cooking dinner | when I came home. |
- when 放在短动作前面:when it started;
- while 放在长动作前面:while I was walking(这里也可以用 when)。
两个分句都可以前后调换;从句放在前面时要加逗号: When I came home, she was cooking dinner.
中文母语者的常见错误
已针对你的语言编写两种时态只用一种。
✗ When I came home, she cooked dinner——意思是她在你回来之后 才开始做饭。汉语的“在”“正在”常常可加可不加,动词本身也不变,所以很容易只用刚学会的过去式。要说“我回家时她正在做饭”,英语必须用进行时:she was cooking。
丢掉 was / were。
✗ I reading a book when the phone rang
✓ I was reading a book when the phone rang
。和 A1 第25课一样,-ing 被当成了“在”, be 就丢了。过去进行时也是两个词,第一个是 was 或 were。
短动作前用 while。
✗ While I came home
✓ When I came home
。 when 和 while 都能译成“……的时候”,可是 while 只能放在长动作前面。
发音
3 分钟-ing 前面的 was 和 were 要弱读: /wəz/ 和 /wə/。重音落在实义动词上: I was working。
否定时正相反,它们要重读:I wasn't working。I was working 和 I wasn't working 听起来的区别,主要在重音和长度上,而不只在 n't。
