Unit5 Nature's Temper过去进行时讲解与练习-2025-2026学年人教版英语八年级下册

Unit5 Nature’s Temper过去进行时讲解与练习 一、基本用法 1.过去进行时的概念 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。 2.过去进行时的构成 过去进行时由“助动词be的过去式(was/ were)+动词-ing”构成。 当主语是第一人称和第三人称单数时,要用was,其他则用were. Linda was drawing pictures at five yesterday afternoon. 昨天下午五点琳达正在画画。 The children were doing their homework from 6:00 to 8:00 yesterday evening. 昨晚六点到八点孩子们正在做作业。 3.过去进行时的基本句式 结构 肯定句 主语+ was / were +动词-ing+其他. In 2022, she was studying in a university. 2022年的时候她在上大学。 否定句 主语+ was / were not +动词-ing+其他. This time yesterday Jack was not watching TV. He was repairing his bike. 昨天这个时候，杰克不是在看电视，而是在修理自行车。 一般疑问句 Was / Were +主语+动词-ing+其他？ 肯定回答：Yes,主语+ was / were. 否定回答：No,主语+ wasn't / weren't. Were you playing basketball at four yesterday afternoon? 昨天下午四点你们在打篮球吗？ Yes, we were./ No, we weren't. 是的,我们在打。/ 不,我们没打。 特殊疑问句 特殊疑问词+ was / were+主语+动词-ing+其他？ What were you doing at this time yesterday? 昨天这个时候你在做什么？ What was he researching all day last Sunday? 上周日他一整天都在研究什么？ 时间标志词 then, at that time, at ten yesterday, at this time yesterday, this morning, the whole morning, all day, from nine to ten last evening, when, while等。 二、特殊用法 1.过去进行时while和when引导从句的区别 (1)由when引导的时间状语从句，主句用过去进行时，从句应用一般过去时； 由while引导的时间状语从句，主句用一般过去时，从句应用过去进行时。 When the teacher came in, we were talking.当老师进来的时候，我们正在讲话。 当此句改变主从句的位置时，则为：While we were talking, the teacher came in. (2)如果从句和主句的动作同时发生，两句都用过去进行时的时候，多用while引导。 They were singing while we were dancing.当我们正在跳舞的时候他们在唱歌。 2.过去进行时表达感情色彩 过去进行时表示对过去经历的主观感情色彩，如赞扬、不满、厌烦等。 He was forever complaining about something.他总是抱怨。 三、难点突破 1.过去进行时表示过去某一段时间内一直进行的动作，常与the whole day, all day yesterday等时间状语连用。有时没有明显的时间状语，可根据上下文语境判断。 We were having classes all day yesterday.我们昨天一整天都在上课。 2.过去进行时表示过去某一时刻正在进行或发生的动作，与表示过去某一时间点的时间状语连用，如at three o'clock yesterday afternoon, at this time yesterday等。 I was taking a walk at nine last Monday morning.上周一上午九点我正在散步。 课后作业·测评 基础练习 一、单项选择 1.I ______ TV at eight last night.
