老师：各位同学大家好，欢迎来到北京市中小学空中课堂，我是来自北京市陈金伦中学分校的实力老师，很高兴能和大家一起学习外研版八年级上。
学生：module seven unit three language in use。
老师：请大家和我一起开启今天的学习之旅。
学生：first。 Of all, let's look at the pictures from the story called Alice's Adventures in Wonderland. What's happening? Alice was sitting with her sister by the river. It was sitting in a tree and smiling at everyone. They were having a tea party in the garden. Look at the sentences once again.
学生：Alice was sitting with her sister by the river. It was sitting in a tree and smiling at everyone. They were having a tea party in a garden. What do the sentences have in common? Yes, they are all in past continuous.
老师：过去进行时强调过去某一时刻或时段正在进行或持续的动作，其基本结构是主语加 was 或 were 加动词的现在分词形式加其他成分。
学生：lets practice what we have just learned。
老师：请同学们关注句子当中的时间状语。
学生：at that time at this time last week when he called me。
老师：这些时间状语都表示过去某一时刻或某一时段，因此我们将使用过去进行时。所以正确的句子依次是，one。
学生：they were listening to music at that time two what were you doing at this time last week， i was preparing for the English test three i was having dinner when he called me。
老师：关注语境当中的时间状语可以帮助我们更好的理解过去进行时。
学生：Now, look at the pictures and answer the questions. What was she doing at 5:00 yesterday afternoon? She was riding a bike. What were you doing at 9:00 last Monday? We were having a class. What were they doing this time yesterday? They were having a picnic. What was he doing when you got home? He was cooking a meal.
学生：Since we are more familiar with past continuous, why not write sentences about what you were doing? You can find this in your book on page sixty. Activity, too. Pay attention to these phrases at about 7:00 last night, this morning during breakfast, this time last year, last Saturday, from about one PM to four PM and we know we'd better use past continuous. Now, I'll tell you what I was doing.
学生：1. At about 7:00 last night I was having dinner. 2 this morning during breakfast I was listening to news 3. This time last year, I was traveling around China. 4 last Saturday from about one PM to four PM I was reading my favorite. book。
老师：那么过去进行时和我们以前学过的一般过去时有什么区别？是比较。
学生：Laura was reading a novel at eight oclock last night Laura read a novel last night。
老师：通过以上两个例句可以看出，这两种时态虽然都表示过去发生的事情，但是过去进行时强调过去某一时刻或时段正在进行或持续的动作。一般过去时表示过去的时间里所发生的动作，所表示的动作往往已经完成。 Now.
学生：Let's see some examples of past continuous and past simple. Underline the correct words in sentences. You can find this in your book on page sixty, activity one 1. Suddenly, all the lights in my house were going off. Oh, went off. there was heavy rain outside。
老师：关注句中 suddenly 一词可知灯灭发生在一瞬间，而且这个动作已经完结。因此，我们使用一般过去时正确的句子，因为。
学生：suddenly all the lights in my house went off， two i caught you up at seven oclock last night， but nobody answered ready im sorry but i was teaching or
