过去进行时一、概念 过去进行时表示在过去某一时刻正在进行的动作，或者表示过去一段时间内持续进行的动作。 二、过去进行时的时间： 过去进行时的时间有：⑴表示过去的具体时刻,如：at this time yesterday, at that time , this time last week, at seven the day before yesterday morning, at that moment, then; ②过去的一段时间：from 1 to four yesterday afternoon ⑵以when（当…的时候，在这时），while（与…同时）连接的从句 三、过去进行时的构成 过去进行时的动词谓语部分有助动词be(was, were)+动词的ing形式（现在分词）构成。动词现在分词的构成遵从'一般、去e , 双写'六字（母）规则。见现在进行时部分。 四、过去进行时用法典型示例 ㈠在过去某一时刻正在进行的动作. ①They were playing football at 8:30 last Sunday.上星期8点他们正在踢足球。 ②They were playing Pingpang this time yesterday.昨天的这个时候他们正在打乒乓球。 ③I was writing a letter at that time.在那时我正在写信。 ④What were you doing at 8:00 the day before yesterday?前天上午8点你们在赶什么？ ㈡过去一段时间内持续进行的动作 ① We were playing basketball from 3 to five yesterday afternoon.昨天下午3到5点我们在打乒乓球。 ②They were learning English last autumn.去年秋天他们在学习英语。 ㈢以when（当…的时候，在这时），while（与…同时）连接的从句 ①I was cooking when he knocked at the door.当他敲门的时候我在做饭。 ②He knocked at the door. when I was cooking他敲门了，这时我在做饭。 ③I dropped my pen when I was walking in the park.我掉了我的笔这时我在公园里走。 ④My mother was cooking while my father was reading.我的妈妈正在做饭与此同时我的爸爸在读书。 五、现在进行时的句型变换 过去进行时的句型变换可遵从以下规则：be若提前变疑问，be后not变否定。（特别注意：动词后面ing的不能丢掉）。 例句：I was planting trees on the hill at ten yesterday. 否定句: I was not planting trees on the hill at ten yesterday. 疑问句: Were you planting trees on the hill at ten yesterday. 肯定回答:Yes, I was. 否定回答:No, I was not. 对trees提问:What were you planting on the hill at ten yesterday. 对planting提问: What were you doing with trees on the hill at ten yesterday. 对planting trees提问:What were you doing on the hill at ten yesterday.? 对on the hill提问:Where were you planting trees at ten yesterday? 六、一般过去时与过去进行时的区别 一般过去时与过去进行时都可以和表示过去的时间状语如last night 等连用，但两者意思差别很大,这时一般过去时表示动 作已经完成，而过去进行时表示在过去的某段时间里动作正在 进行，动作不运一定完成。例句： 16 ①I wrote a letter last night.（昨天晚上我写了一封信——信已经写完） I was writing a letter last night. （昨天晚上我在写了一封信——信不一定写完） ②We built a school last year (去年我们建了一所学校—— 学校已经建立起来了). We were building a school last year.（去年我们在建学校——学校不一定建起来） 练习 1. While we __________ (wait) for the bus, a girl __________ (run) up to us. 2.
