3) 完成P40 Self check 2
阅读短文，用括号中所给单词的正确形式填空。这个语篇虽短，但语境丰富，并且较好地呈现了一般过去时和过去进行时的配合使用。值得背诵与模仿。

II. when, while
1. 由when引导的时间状语从句，主句用过去进行时，从句应用一般过去时；
由while引导的时间状语从句，主句用一般过去时，从句应用过去进行时。
e.g. the teacher came in, we were talking.
当此句改变主从句的位置时，则为： we were talking, the teacher came in.
2. 如果从句和主句的动作同时发生，两句都用过去进行时的时候，多用while引导。e.g.： They were singing we were dancing.
当我们在跳舞时他们在唱歌。
