　　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.

　　2．利用图片或动作表演进行教学

　　教师展示给学生一些事情正在发生的图片，让学生描述图片中的人或物那时正在干什么？比如给下面的图片让学生描述：

　　T: What was the man doing last night?

　　He was cooking. I think he is a cook.

　　What was the boy doing yesterday?

　　He was playing computer games. I think he is interested in computer.

　　教师可让一组学生来做动作，然后用另一组学生他们刚才正在干什么？

　　What were they doing?

　　They were jumping.

　　3．比较过去进行时和一般过去时都用于表示过去发生的动作，但前者表示正在进行的动作，后者表示一个完成的动作。例如：

　　1) I was drawing an elephant yesterday evening. 昨晚我在画象。（可能没画完）

　　2) I drew an elephant yesterday evening. 昨晚我画了一匹象。（已经画完了）

　　3) He was reading a story-book last week. 上个星期他在读一本小说。（还没读完）

　　4) He read a story-book last week. 上个星期他读了一本小说。（读完了）

　　用幻灯打出如下几组句子：

　　1．

　　2．

　　3．

　　让学生分析过去进行时与一般过去式的区别。在学生分析的基础上老师进行总结，告诉学生两种时态的不同点。过去进行时强调在过去某一特定时间正在进行的动作。而一般过去时则表示在过去某一时间所发生的动作或存在的状态，其表示的动作往往已经完成。最后通过做练习册第对课的练习3，第94课的练习，第94课的练习2，3，检查学生掌握的程度。

　　教学词汇和习惯用语

　　在语境中讲解新词语的意思，这就是说要结合课文讲解。其次，讲解应尽量用英语，以培养直接用英语思维，而且应力求生动形象，以助记忆。

　　1．用实物教学

　　例如教师拿出一只靴子，问What’s this in English?帮助学生回答：boot。可用实物或图片教boots, truck, a pair of scissors等词。

　　2．用表情和动作教学 例如：教upstairs 和downstairs时，教师可用书中插图说明This man lives upstairs and this man lives downstairs. 又可用简笔画表示go downstairs / upstairs(如下图)而且还可做上下楼的动作示意。

　　教angry时，教师故意批评另一个班的学生说：They don't work hard. They always make a lot of noise. Many of them did badly in their test. It made me very angry.教师瞪大眼睛摆出一副十分生气的样子。

　　3．可用讲小故事的方法教学be angry with, 例如：Last week Xiao Ming borrowed my bike. He said he was going to let me have it back soon, but he's still using it. I'm rather angry with him.

　　教help…with 这个短语，教师可说Tang Hulin finds English very hard. Lin Tao is good at English , so he often helps Tang Hulin with his English.
