英语语法过去进行时讲解与习题

过去进行时讲解与习题过去进行时是表示过去某一时刻或某一时间内正在进行或发生的动作。可以从两个方面来理解：1 过去某一时刻正在进行或发生的动作。They were playing football at ten oclock yesterday morning. My mother was cooking when I got home. I was washing my clothes at this time yesterday. 2 过去某阶段持续进行的动作 What were you doing during the holiday? 另外，在复合句中，若主要动作和背景动作是同时发生的，那么主从句都可用过去进行时Jenny was reading while Danny was writing.其结构是助动词be的过去形式was/were +v-ing.其句式变化仍然要在be上做文章。We were working in class.We werent working in class. Were you working in class?过去进行时常与过去某一特定时间的状语连用，如 last night, at that time, at noon yesterday, last Sunday 等。 也有时没有时间状语，要通过上下文的暗示来确定用过去进行时。The students all worked hard. Everyone knew what he was working for.1.过去进行时的构成 过去进行时是由“was / were +现在分词”构成的。 I was doing my homework at this time yesterday. 昨天的这个时候我正在做作业。 Were you expecting him yesterday? 你昨天一直在等他吗？ They were not talking when I came in. 我进来的时候他们没在说话。 2. 过去进行时的用法 过去进行时的基本用法 a.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。 提示： 当句子意思很清楚时，我们也可以把两个动词都换成一般过去时。 We listened closely while the teacher read the text. 老师读课文时，我们都仔细地听着。 b.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。 He was watching TV at home from 3:00 to 5:00 yesterday afternoon. 昨天下午从3点到5点他一直在看电视。 c. 表示按计划、安排过去将要发生的事 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。 过去进行时的特殊用法 a.表示故事发生的背景 It was snowing as the medical team made its way to the front. 那支医疗小组往前线行进时天正下着雪。 Tom slipped into the house when no one was looking. 汤姆乘没人注意时溜进了房间。 b.表示一个新的动作刚刚开始 过去进行时可用来引出一个新的动作，这种用法颇有点儿像镜头转换。 Five minutes later, he was standing at the door, smoking. 5分钟后，他已站在门口抽着烟。 The baby was crying hard, and suddenly the crying stopped. 这婴儿在大声啼哭，突然，哭声停止了。 c. 用来陈述原因或用作借口 She went to the doctor yesterday.

(对划线部分提问) What were you at 5:00 p.m. yesterday?答案：What were you doing at 5:00 p.m. yesterday?解析：现在进行时中“Whatdoing”?句式同样适用于过去进行时。四、易与现在进行时弄混例：My mother is cooking (cook)when I got home.答案：was cooking解析：这两种时态的共同点是都表示动作正在进行，但现在进行时前提是现在，而过去进行时前提是过去，由when I got home可看出前提是过去。五、易与一般过去时弄混例：昨晚我在读一本故事书。 I read (read) a story book yesterday evening.答案：was reading解析：这两种时态的共同点是都用于表示过去发生的动作。但过去进行时强调动作正在进行，而一般过去时则表示过去某一时间所发生的动作或存在的状态，它表示的动作往往已经完成。“在”说明正在进行，而“I read a story book yesterday evening.”的意思是昨晚我读了一本故事书，言下之意已经读完了。故用过去进行时。另外，在宾语从句中当主句为过去时，从句若是现在进行时，需变成过去进行时。He said that he was drawing a cat at noon yesterday.自主训练：（一 ）、单选参考答案：1 D 2 C 3 B 4 C 5 A 6 B 7 A 8 D 9 D 10 B 11 A1 What _ from three to four yesterday afternoon?A have you done B had you done C did you do D were you doing2 I call you yesterday evening, but there was no answer. - Oh., Im sorry I _ dinner at my friends home.A home B had C was having D have had3 My mother _ while my father _TV.A cooked; was watching B was cooking; was watching C was cooked; watched D cooked; watched4 When I got home, my son _ the music.A am listening to B listened to C was listening to D was listening5 We heard a cry when we _ TV last night.A were watching B would watch C watch D watched6 She asked him whether he _ back for lunch.A come B was coming C came D had come7 Could you tell me when _?A she is coming B she was coming C will be come D is he coming8 The teacher _ when I came into the classroom.A
