Step 1 Revision

 1. 过去进行时基本概念  [来源:Z_xx_k.Com]

过去进行时表示在                  时间内                      动作。这一特定的过去时间除有上下文暗示以外, 一般用时间状语来表示。

  2. 结构：“was/were + v-ing”                                  

Step 2  Pairwork

1.Talk about what the people in picture were doing at the time of the rainstorm.

2.Make up sentences.

Step3  Grammar Focus

一．按要求完成练习, 并总结出句子中包含的语法。

2. She                    (do )  her homework at the time of  the rainstorm.[来源:学。科。网]

3. He was reading in the library when the rainstorm      (come).

4. When it began to rain, Ben was helping his mom make dinner.(翻译句子)

5. While Linda                       (sleep)，Jenny was helping Mary with her homework.

  B: Linda在睡觉的时候, Jenny在帮助玛丽做作业。

Step 4  过去进行时中的when和while

 when和while都可表示“当……的时候”，引导时间状语从句。你知道两者在过去进行时中的用法有什么不同吗？请仔细观察下面的例句，然后补全空格中的内容。

① I was walking to school when I saw a cat in a tree.    

②When Sally got home, her mother was cleaning the house.

③ While I was sleeping in the bedroom, someone knocked at the door.

④ David fell while he was riding his bike.
