教学过去进行时

动词的过去进行时表示过去某一时刻或某一时间内正在进行或发生的动作。它的结构为was(were)+ 动词 -ing。老师在讲授这一时态时不必泛泛而谈它的语法功能，而要在与现在进行时和过去式的比较中逐步理解和掌握。

1.呈现第93课由现在进行时入引出过去进行时，这是传统的有效方法。

老师用幻灯或直接在黑板上写出一些含有现在进行时的句子。例如：

1. The teacher is talking with some students in the classroom, now.

2. They are listening to music in the next room, now.

3. What’s Li Lei doing? He’s drawing a picture on the blackboard.

4. What are your parents doing? They are watching TV.

5. My English teacher is writing a novel these days.
