课题：牛津初中英语‎8 A Unit 6 Natural Disasters 第四课时 Grammar ‎ 班级： 　姓名：　　 　时间： 年 月 日 一、 学习目标 ‎ 1. 进一步学习过去进行时态 ‎ 2 . 学习while和when 在过去进行时态 ‎ 二、 自学 ‎ 1 根据英文写出汉语意思 ‎2. 语法点讲解 一、过去进行时的概念及构成过去进行时表示过去某一时刻或某段时间正在进行的动作。过去进行时由“was/ were+动词-ing”构成。‎ 二、过去进行时的用法 ‎ ‎①过去进行时的基本用法 ‎★表示在过去某一时刻正在发生的动作或该动作与过去的另一动作同时发生。 I was having supper at 7:00 yesterday evening.   昨天晚上7点我正在吃晚饭。 She was playing the piano while I was reading the newspaper.    她弹钢琴时 我在看报。‎ ‎★表示过去一段时间内正在进行的动作。 We were talking about you the whole morning.  我们整个上午都在说你。‎ ‎★表示按计划、安排过去将要发生的事。用于come, go, leave, start, arrive等表示位置转移的动词时，也可以用过去进行时表示过去将要发生的动作。如： He told me that he was going soon.      他告诉我他很快就要走了。 She said she was leaving for New York the next month.  她说她下个月动身去纽约。‎ 一般过去时和过去进行时的比较         1、过去一般时表示的是过去经常发生的动作或状态。而过去进行时表示的是过去某一时刻正在进行的动作。因此，它们在使用的时间词语上有着比较明显的区别。那就是，一般过去时所指的过去时间却比较笼统，而过去进行时所指的过去时间则比较具体，并含有“当时正在做某事”的意思。试比较下面两组句子： 例1： 她三年前加入了团组织。 请选择_________‎ A. She joined the League three years ago.        B. She was joining the League three years ago.‎ ‎ 例2： 玛莉昨天这个时候正在洗衣服。 请选择_________‎ A. Mary was doing some washing at this time yesterday.        B. Mary did some washing at this time yesterday..      例1中的three years ago所指的过去时间均较为笼统；而例2中的at this time  yesterday  所指的过去时间均较为具体。     2、过去一般时表示的是某个动作是否发生过，而不太关注这个动作持续的时间；过去进行时却侧重于某个动作持续的时间长短。‎ 4‎ 请比较下列例子：                 1. Jack wrote a letter to his parents last night.  [信写完了]            Jack was writing a letter to his parents last night. [信不一定写完]      2. They planted trees last Sunday.  [树植完了]            They were planting trees last Sunday. [树不一定植完] 2. 认真预习以上知识, 用适当时态填空 ‎1）Mary _____________ (make) a dress when she cut her finger.　‎ ‎2）When she __________ (read) the newspaper, Granny fell asleep. ‎ ‎3) I ________________（drive） a car at ten o’clock last night. ‎ ‎4) The teacher_________________ （talk）to some students when I saw her.‎ ‎ ‎ ‎ 做完后，请自己总结过去进行时态的用法 ‎ _________________________________________________________________‎ ‎ _________________________________________________________________‎ 三 课堂活动 四 随堂检测 一、 用所给单词的正确形式填空 ‎1.
