教学过去进展时
　　（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，而要在和如今进展时和过去式的比较中逐步理解和掌握。
　　1．呈现第93课由如今进展时入引出过去进展时，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如今进展时的句子。例如：
　　1. The teacher is talking with some students in the classroom， now。（精品文档请下载）
　　2. They are listening to music in the next room, now.（精品文档请下载）
　　3. What’s Li Lei doing？ He’s drawing a picture on the blackboard。（精品文档请下载）
　　4. What are your parents doing? They are watching TV.（精品文档请下载）
　　5。 My English teacher is writing a novel these days.（精品文档请下载）
　　通过这些句子复习如今进展时的构造，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。（精品文档请下载）
　　2. They were listening to music in the next room at ten o’clock yesterday.（精品文档请下载）
　　3。 What were your parents doing when your brother came back？ They were watching TV.（精品文档请下载）
　　4。 What was Li Lei doing when the teacher came in？ He was drawing a picture on the wall。（精品文档请下载）
　　5. My son was learning English in Australia last autumn。（精品文档请下载）
　　 告诉学生在这些句子中都含有过去进展时。老师和学生一起进展分析比较,归纳出过去进展时的构造和用法,及和如今进展时的区别。（精品文档请下载）
　　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化
