(Yes, he was./ No, he wasn’t.) →What was he doing at 5:00 yesterday? 行业PPT模板http:///hangye/ 过去进行时用法 1. 过去进行时主要表示过去某个时刻正在进行的动作，常和表示过去的状语连用。如： （just）then 那时，当时 at this/that time 在这/那时 yesterday afternoon昨天下午 at nine 在九点 last night 昨晚 （at）this time yesterday在昨天这个时候 但在不少情况下，没有表示时间的状语，这时需要通过上下文来表示。 ①What were you doing at nine last night? 昨晚九点的时候，你在做什么？ ②I was watching TV at home yesterday afternoon. 我昨天下午正在家里看电视。 ③They were playing football at this time yesterday.昨天这个时候他们在踢足球。 行业PPT模板http:///hangye/ 过去进行时用法 2.过去进行时也可以表示过去某一段时间内正在进行的动作。常与those days, the whole morning, from 8:00 to 12:00 last night等时间状语连用。 （1）From 1983 to 1998 , he was teaching at Yale . 从1983到1998年，他正在耶鲁大学教书。 （2）They were building a bridge last winter . 去年冬天他们正在造一座桥。 (3) He was writing a book those days. 那几天他正在写一本书 行业PPT模板http:///hangye/ 过去进行时用法 3.过去进行时与频度副词always forever， continually， constantly等连用时表示过去经常反复的动作，常常带有埋怨、讨厌、赞扬或喜爱等情绪。 ⑴My sister was always forgetting things.(表示埋怨) ⑵He was always helping others. (表示赞扬) 行业PPT模板http:///hangye/ 过去进行时用法 4. 过去进行时表示过去将要发生的动作。 现在进行时可以表示将来的动作，同样，过去进行时也可以表示从过去某时看来将要发生的动作，常用在间接引语中。 ①Lucy arrived in Beijing last Friday. But she was leaving for Hong Kong the next morning. 上周五Lucy到达北京，但第二天早晨就要动身去香港了。 ②She asked him if he was coming back for lunch. 她问他午饭是否准备回来吃。 行业PPT模板http:///hangye/ 过去进行时用法 5. 使用过去进行时应注意的几点 (1) 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? 行业PPT模板http:///hangye/ 过去进行时用法 6.过去进行时表示婉转语气(只限于want, hope, wonder 等动词)，用以提出请求。如： I was wondering if you could help me. I was hoping you could send me home. 行业PPT模板http:///hangye/ 过去进行时用法 7.when, while 的用法 when和while与过去进行时有着密切的关系，他们作从属连词时都有“当…….时候”之意， ①when引导的时间状语从句的谓语动词可以是短暂性动词，也可以是延续性动词，而while引导的时间状语从句中的谓语动词只能是延续性动词。 ②when引导的从句谓语动词如果是短暂性动词则用一般过去时，主句是延续性动词则用过去进行时，从句动作发生在主句动作的时间段之内（长动作用过去进行时，短动作用一般过去时）；如果主句和从句两个谓语动词都是延续性动词则全部用过去进行时,这时when和while都可以用。 ③when从句的谓语动词可以在主句谓语动作之前、之后或同时发生；while和as从句的谓语动作必须是和主句谓语动作同时发生。 ④when和while两个词还可以用作并列连词，但意思不同，when相当于“在那时”，等于at that time或just then;而while则相当于“而；却；但是”；相当于but,表示对比关系。（这一点暂时可以不掌握） A Actions happening in the past at a particular time We can use the past continuous tense to talk about actions that were happening at a particular time in the past.
