二、合作探究、质疑解惑:

1. ―What were you doing when the rainstorm came? 当暴风雨到来时你在干什么？

  ― I was waiting for the bus. 我在等车。

    此句是过去进行时，下面我们讨论一下过去进行时的用法。

 1. 过去进行时的定义:

过去进行时主要表示过去某一时刻正在进行的动作，或表示过去某一阶段一直在进行的动作。例如：I was eating with Tom at 8:00 yesterday. 昨天八点我与汤姆一起吃饭。    

2. 过去进行时的结构:

 过去进行时由“was / were + 现在分词”构成。例如：I was doing my homework then. 那时，我在做作业。

3. 常用的时间状语: at that time、this morning、the whole morning、from nine to ten last evening、when、while 例如：We were having a birthday party from seven to nine last night. 昨天晚上七点到九点的时候我们在举办生日聚会。　　        

你能将She was walking home at that time. 改为否定句和一般疑问句吗？

否定句：                                      .                                      

一般疑问句：                                  ?                                      

2. I didn’t see a car coming. 

 译为                                         .

see sb. doing sth. 看到某人正在做某事, see sb. do sth. 看到某人做某事全过程。与该用法相同的单词有：watch, notice, hear, look…

例如：昨天我们看到他正在操场上打蓝球。Yesterday we saw him           on the playground.     

3. Why did you call so many times?

译为                                         ?

   so many times 那么多次，so many 后面跟可数名词的复数，so much后面跟不可数名词。例如：他去过历史博物馆许多次。He went to the history museum                    .

外面嘈杂声很大，以致我们不能听到老师的话。There was                     outside that we couldn’t hear the teacher.

4. I was in the kitchen helping my mom.  

译为                                         .

helping my mom 帮助我的妈妈，动名词作伴随状语。例如：他站在风中等他的妈妈。He stood in the wind             his mother.

5. I called at seven and you didn’t pick up.

pick up 接电话，拾起，接某人。例如：Can you help me pick up the book? 你能帮我拾起书吗？
