课堂教学设计:
一. 过去进行时的定义
过去进行时主要表示过去某一时刻正在进行的动作,或表示过去某一阶段一直在进行的动作。如:
I was having a talk with Li Hua at that time. 那时,我正在跟李华谈话。 I was watching TV at home last night. 昨晚我一直在看电视。
二. 过去进行时的结构
过去进行时由“was / were + 现在分词”构成。如:
I was doing my lessons then. 那时,我在做功课。
We were cleaning the house. 我们在打扫房子。
三、 使用过去进行时应注意的几点
1 过去进行时可表示按计划、安排过去某时刻将要发生的动作。如: He said they were leaving for Beijing this afternoon. 他说他今天下午要去北京。 2 动词hope, wonder 等的过去进行时常用来表示提出要求,虽然表示现在的内容,但语气比一般现在时或一般过去时要委婉。如:
I was wondering whether you could come to join us. 我想你能否过来跟我们一起活动?
3过去进行时中有always, forever, continually, constantly修饰时,表示说话人的赞赏或厌烦的感情。如:
He was always thinking of others. 他总是想到人家。
4. 过去进行时和一般过去时的区别
1)过去进行时表示过去正在进行的动作,而一般过去时则表示一个完整的动作。如:
They were writing letters to their friends last night .
昨晚他们在写信给他们的朋友。(没有说明信是否写完)
They wrote letters to their friends last night .
他们昨晚写了信给他们的朋友。(表达了他们已写好的意思,整个写的过程已完成。)
2)当动作延续较长时间时或表示厌烦、赞美等感情色彩时,常用过去进行时表示。如:
He was thinking more of others than of himself .
他考虑别人的比考虑自己的多。(表示说话者赞扬的口气)
The boy was always making trouble then .
那时,他总是惹麻烦。(表示说话者厌烦的口气)
