2018-11-21 17:07:00来源:网络

  新东方在线中考网整理了初二英语上册知识点总结一般过去进行时,供同学们参考。

  1.过去进行时的构成:动词be的过去式was /were+动词的现在分词构成。

  (1)过去进行时的否定式是在动词be后加not构成。例如:

  He wasn’twatching TV when his mother came back.

  妈妈回来的时候他没在看电视。

  We weren’tplaying basketball when he arrived.

  他到的时候我们没有打篮球。

  (2)过去进行时的疑问句是将动词be(were, was)移至句首。例如:

  Wereyou playing the computer games at 10 last night?

  昨天晚上10点你在玩电脑游戏吗?

  Wasyour brother doing his homework at this time yesterday?

  你哥哥昨天这个时候在做作业吗?

  注意:

  ①I was 不能缩写成I’s ; They were, We were不能缩写成They’ere, We’ere

  ②有些表示感情知觉和状态的动词一般不用于进行时态,如:see, hear, love, like,know, remember, understand,have等。

  2.过去进行时的用法:表示在过去某一时间内正在进行的动作。例如:

  I was watching TV at that time.

  那时我正在看电视。

  He was cooking at 12 o’clock yesterday.

  昨天12点时他正在做饭。

  When I came in, she was writing a letter.

  我进来时她正在写信。

  The students were talking about the movie when the teacher came in.

  老师进来时学生们正在谈论那部影片。

  3.过去进行时还可以用来表示在过去某阶段正在进行的动作或存在的状态。例如:

  They were waiting for you yesterday.

  昨天他们在等你。

  He was studying in a middle school at that time.

  那时他在中学念书。

  4.过去进行时行时与一般过去时的区别:

  过去进行时表示在过去某时间里正在进行的动作或存在的状态,一般过去时则表示一个发生在过去的动作或状态,一般说来该动作已完成。例如:

  They were writing a letter to their pen-pals last night.

  (表示他们在昨晚某时刻正在做的动作,但不强调信是否写完)

  They wrote a letter yesterday.(表示一个完整的动作)

  辨析:when与while

  (1)when adv. (关系副词)当…… 时;(疑问副词)什么时候,何时

  When will he come? 他什么时候来?

  It was raining when they started. 他们动身时正下着雨。

  We’ll start when the team leader comes. 队长一来,我们就出发。

  (2)while conj. 当……的时候,和……同时

  While he was eating, I asked him to lend me $ 2.

  当他正在吃饭时,我请他借给我2美元。

  when=at that time 当……的时候,其动作可以是延续性动作,也可以是瞬间的动作。

  e.g.When I came in, he was reading.

  When I was a child, I liked soccer very much.

  while=during the time that… 在……期间,与其连用的动作通常是延续性的动作,不与瞬间的动词连用(其引导的从句通常用过去进行时)。

  While her children were doing their homework, she was doing some housework.

  当她的孩子们在做作业时,她在做家务活。

  While the students were reading the new words, the teacher walked around in the classroom.
