过去完成时

The Past Perfect Tense

过去完成时的构成

过去完成时由助动词had (通用于各种人称和数)+过去分词构成。主要表示过去某时前已发生的动作或情况(也可说是过去的过去):

By the time I got there, it had already finished.

When I got to the check-out, I realized I had left my purse at home.

He said he had never seen such an exciting match before.

注:如果时间状语从句的动作发生在前,则从句用过去完成时,主句用一般过去时。

When he had finished his work , he left his office .

After I had done my homework , I went to bed.

陈述句

They had already had breakfast before they arrived at the hotel.

在他们到达旅馆之前,他们已经吃早饭了。

从句中arrived at到达在过去的时间,而had already had吃早饭的动作发生在到达之前,因此主句的时态为过去的过去。

I had finished writing my composition by 10:00 this morning. 今天上午10:00点以前,我已经写完了我的作文。

She had searched the internet for two hours when she found an ad for the Canon digital camera. 当她找到了佳能数码照相机的广告时,她已经在因特网上查询了两个小时。

I went over what I had written again and again so that I wouldnt make any mistakes. 我一遍又一遍地检查了我所写的内容,以至我没有出现任何错误。

否定句

He remembered he hadnt paid for it yet. 他记得他还没有付账。

He said that he had never seen such a beautiful bird before.

他说他以前从来没有看过这样美丽的鸟。

疑问句

How many English films had you seen by the end of last term?

到上学期期末为止,你们看了多少部英文片?

Had you reached the station before ten oclock?

十点以前,你们已经到达火车站了吗?
