While the girl was shopping ,the alien got out. 当外星人离去的时候那个女孩正在购物。 5.The boy was walking down the street when the UFO landed. While the boy was walking down the street , the UFO landed. 当 UFO 着陆时那个男孩正沿着街道走。 二、过去进行时:表示在过去某一时刻或某一段时间正在进行的动作。 1.构成:was / were + 现在分词(其中 was 是 am、is 的过去式,were 是 are 的过 去式) e.g. I was doing my homework then . 那时,我正在做作业。

2

用法:1)过去进行时表现过去某一时刻正在进行的动作。 e.g. She was writing a letter when I came in .我进来时,她正在写封信。 2)过去进行时还表示过去某阶段正在进行的动作。 e.g. They were waiting for you yesterday .他们昨天一直在等你。 2.基本句型如下: 肯定句:主语 + was / were + V-ing + ~~~ 否定句:主语 + was / were not + V-ing + ~~~ 一般疑问句:was / were +主语 + V-ing + ~~~ ? 特殊疑问句:when / what /who /~~ + was / were + 主语 + V-ing + ~~~ ?

★过去进行时与一般过去时的区别; 过去进行时:表示正在进行的动作。 I was reading a novel last night.昨晚我在看小说。(可能还没有看完) 一般过去时:表示一个完成的动作。 I read a novel last night .昨晚我看了一本小说。(已经看完了) 三、以 when 和 while 引导的时间状语从句 1)延续性动词指动作可以延续一段时间,而不是瞬间结束。 如:work,study,drink,eat 等。 2)非延续性动词指动作极为短暂,瞬间结束。 如:start,begin,arrive,jump,go,finish,borrow,knock 等。 ★ when 表示?当……的时候?。它后面既可跟延续性动词,又可跟非延续性动词. 如:Mary was having dinner when I saw her . (当我看到玛丽的时候,她正在吃饭.) ★ while 表示?在……的时候?、 ?在……期间?。 while 后面必须是表示动作或状态 的延续性动词。 如:The weather was fine while we were in Beijing .(当我们在北京的时候天 气很好.) 所以, when 可指时间点,又可指时间段,从句中可用延续性动词,也可用非延续性 动词。 while 总是指一个时间段,从句中必须用延续性动词。 学习过程: 1.小组合作看图 1a ,讲故事。谈论图中发生的故事。
