The teacher writes “ What are you doing? ”on the blackboard and asks in Chinese:这是什么时态? 引导学生回答，复习现在进行时态的意义及结构（am/is/are + doing）。再问这位学生:“What were you doing when I came in?”引入过去进行时态(was/were + doing)，板书课题,引出本节课的教学任务。进而引出本课的重点内容过去进行时Step 3 Learn the new tense承接导入部分进一步讲解过去进行时：Language points 过去进行时态: 表示在过去某一时刻或某一段时间内正在进行或持续进行的动作。其结构为:主语be的过去式was/were动词的现在分词其他。其中be随主语的人称和数的变化而变化。当主语是第一人称或第三人称单数时用was，主语是第二人称或第一、三人称复数时用were。I was watching TV at that time.那个时候我正在看电视。这是过去进行时态的简单句形式， 过去进行时态的否定形式为：was/were not + doing (wasnt / werent) 过去进行时态的疑问形式为： Was/Were + doing？ Yes, was. / No, were.注意：过去进行时态常见的时间状语为at that time / at this time / last night / at 8:00 yesterday evening / when + 过去时 请同学们看白板进行练习 Step 4 Practise the new tense 利用课件中的“Guessing games to relax”的活动部分进一步练习巩固过去完成时，让学生在轻松愉悦的情境中掌握过去完成时。 T：Last night，I went to the Boys Dorm(宿舍).

While和when之间可以相互转换，只不过是要选用相应的动词及形式，如：1）When the alien got out, the girl was shopping. = While the girl was shopping, the alien got out. 2）When the UFO landed, the boy was walking down the street. = While the boy was walking down the street, the UFO landed请同学们做下列练习：(师生互动完成此项任务)1). T: While John was playing the piano, Mary left the house. Ss: John was playing the piano when Mary left the house.2). T: While John was cleaning the room, Mary turned on the radio. Ss: John was cleaning the room when Mary turned on the radio.3). T: While John was shopping, Mary took the car to the car wash. Ss: John was shopping when Mary took the car to the car wash. 在熟练掌握when和while的用法后再深入教材，学习就容易多了。Step 7 Work on 2a2d1.认真观察2a中的图片，然后听录音,根据听到的顺序为图片标序号，通过白板集体核对答案。2.再认真听一遍录音，根据对话内容完成2b的填空，完成后通过白板集体核对答案。3.听第三遍录音，学生跟读。4.仿照2c的形式，利用2a中的对话信息复述记者和男孩之间的对话,完成后邀请几组学生表演对话。TV reporter: Tell us what happened yesterday morning?Boy:.TV reporter: So, when the rainstorm suddenly came, what were you doing?Boy:.5. 带着问题研究2d部分，找四名同学解释问题： What was Linda doing at seven last night?Was Linda having a shower at nine last night?Why did Mary call Linda?Who helped Mary at last?看白板大声朗读2d中的对话, 读熟后与同伴解决以上问题，Ask 4 students to give their answers：S1: She helped her mother.S2: No, she wasnt.
