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.
通过这些句子复习现在进行时的结构，is（are）+ v-ing的用法。接下来用幻灯再打出如下句子：
1. The teacher was talking with some students in the classroom this time yesterday.
2. They were listening to music in the next room at ten o’clock yesterday.
3. What were your parents doing when your brother came back? They were watching TV.
4. What was Li Lei doing when the teacher came in? He was drawing a picture on the wall.
5. My son was learning English in Australia last autumn.
告诉学生在这些句子中都含有过去进行时。老师与学生一起进行分析比较，归纳出过去进行时的结构和用法，及与现在进行时的区别。
还可以根据实际情况如下问答：
T: What are you doing now?
S: I am / We are having an English lesson.
T: What were you doing at this time yesterday?
S: I was / We were having a Chinese lesson.
把前两句写在黑板上，然后改变谓语动词等部分成为后两句，使学生对时态的变化有较深刻的印象。一旦学生理解了这两个时态的不同概念，便可开始操练。让学生把现在进行时变为过去进行时。
接下去作问答操练。What were you / was he / … doing at this time yesterday? I / He / She was having…We / They were having…Were you / they having…?Was he / she having …?并用肯定或否定的答语回答。这样操练的目的是训练语言的准确性。
在教学中，要向学生说明：过去进行时常常与过去某一特定时间的状语连用，如本单元所列举的last night, last Saturday, at ten o’clock yesterday morning, at noon yesterday, 还有at that time, (at ) this time yesterday等。但是，有些过去时行时的句子不带时间状语，而是由上下文暗示，例如文中的He was feeling very tired. He was just falling asleep when there was a loud knock at the door. 从上下文可看出时间状语是the next evening.
