Here is a picture of the Tiangong space station. At 7 p.m. yesterday, Nie Haisheng’s family were having dinner. What was Nie Haisheng doing at that time Ss：He was repairing equipment. T：Yes! While Nie Haisheng’s family were having dinner at 7:00p.m. yesterday, Nie Haisheng was repairing equipment. If we want to talk about what someone was doing at a particular time in the past, for example, “He was repairing equipment at 7:00 p.m. yesterday,” what tense should we use ” Ss：We can use the past continuous. T：Yes, that’s right!（教师板书标题：The past continuous） Step 4 总结与归纳 学生阅读课本第105页的解说与例句，在教师的引导下总结过去进行时的含义和结构，教师可以适当进行板书： 肯定句：subject + was/were + verb-ing 否定句：subject + was/were + not + verb-ing 疑问句：Was/ Were + subject + verb-ing 肯定回答：Yes, subject + was/were. 否定回答：No, subject + was not/wasn’t (were not/ weren’t). 学生阅读课本第105页Look部分的内容，了解while一词在过去进行时中的用法，教师可以准备更多例句或提供以下练习，帮助学生更好理解其用法。 用括号内动词的适当形式填空。 While I was cooking dinner, my brother was setting the table.

(take) She was knitting a sweater while he was reading the newspaper. (knit) While I was brushing my teeth, my roommate was making coffee. (brush) 学生回忆一般过去时的结构与使用情境，并对比其与过去进行时的区别，随后完成课本第105页活动1，并与教师核对答案。教师还可以通过提问的形式，延伸太空垃圾的话题，并让学生在回答时进一步体会一般过去时与过去进行时的区别： What happened in space on 11 February 2009 What were the two satellites doing before the crash What things were space agencies tracking before the crash What didn’t they notice Step 5 巩固与运用 教师展示一张宇航员一天活动的时间安排表，并提问：“If you were an astronaut, what would you write in your diary about your daily life in space How would you describe what you were doing ... ...
