一般说来,要表示过去某个时刻或某一时段正在进行的动作,大家常用过去进行时。常和过去进行时连用的时间状语有:then,at this/that time yesterday, at … last night, the whole morning, from … to … last night等。
What were Ben, Jake, Lucy and Lily doing on December 31st, 2011? They _____ their party. Lucy _____ crisps. Lily _____ the music. Ben and Jake _____ chairs and tables. _____their parents _____ them? No, they _____ them because they _____ on the plane on their way to Australia.
【指点迷津】 比如: I was watching TV at this time yesterday. 昨天这时我在看电视。 They were doing their homework the whole morning. 整个上午他们都在做作业。 可以看出,过去进行时由“was/were + 动词-ing”构成,与目前进行时结构相似,只不过目前进行时的am/is/are变成了was/were。由此可以判断,过去进行时的句式变化也应该与目前进行时的一样。 比如: She was having a meeting at that time. → She was not having a meeting at that time. → Was she having a meeting at that time? 那样,怎么样不同并准确用过去进行时和一般过去时呢?试比较: I was typing a letter at seven last night. 昨晚7点我在打一封信。 I typed a letter last night. 我昨晚打了一封信。 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动作,但过去进行时表示在过去某一特定的时间点或时间段正在进行的动作,而一般过去时表示在过去时间完成了的动作。 Key: 1. were preparing 2. was buying 3. was organizing 4. were fetching 5. Were; helping 6. weren’t helping 7. were sitting
