初中英语语法动词八种时态详解--过去进行时

wjp 1172分享

  主要表示在过去的某个时间点上正在发生、进行的动作。由于它的定义是表示在过去的某个时间点上正在发生、进行的动作,所以,句子常带有一个表示“过去某个时间点”的状语。这个状语可能是短语,词组,或是一个从句。也可能是通过上下文来表达这层意思。过去进行时主要用于下面的情景中:

  1)表示在过去某时刻正在进行的动作,例如:

  At this moment yesterday, I was packing for camp.昨天这个时候,我正在收拾东西去露营。

  When I came to see her last time, she was writing an article.上次我来看她的时候,她正在写一篇文章。

  What were you doing at eight last night ? 昨晚八点钟你在做什么?

  2)用于故事的开头,交代故事发生的背景情况。

  过去进行时所描述的动作是“正在进行”,所以,在这种情景中用“过去进行时”可以给读者一种“动感”,从而能使文章更加生动活泼。例如:

  One night, he was typing in his study . Suddenly , a man broke into his house and cut off the electricity … .一天晚上,他正在书房里打字。突然,一个人闯进屋来,切断了电源……

  3)(仅限少数动词)表示在过去的未来时间要发生的动作。例如:

  When National Day was coming near , they began to make a plan for the holiday .国庆节即将来临的时候,他们开始制订度假计划。

  She told me that she was going to Hainan for her holiday. 她告诉我她将去海南度假。

  My friend said to me that he was lunching with one of his customers that day .我朋友对我说,他今天要与他的一位客户一块儿吃午饭。

  We left there when it's getting dark. 天快黑的时候,我们离开了那儿。
