7、过去完成时态

1）过去完成时态的构成：  

                   肯定式：had +动词的过去分词      

                   否定式：hadn’t +动词的过去分词

                   疑问式：Had … +动词的过去分词

                   简略回答: Yes,主+ have/has had.

    No, 主+ had现在完成时的用法

过去完成时的用法：

1、表示在过去某一时间或动作之前已经发生或完成的动作。 他表示的时间是“过去 的过去”常与by last year, by the time of yesterday,等连用。如：

She said she had seen the film 4 times.

When Mr Li got to the classroom, all the students had begun reading.

By the time they arrived, the bus had left.

2、表示 从过去某一时间开始一直延续到过去另一时间的动作或状态。常与for (后跟段时间)或since (后跟点时间)等连用.如:

She had worked in this school since it opened 25 years ago.

例题解析：

1. He ______ in Shanghai University for four years before he ______ Beijing.

A. studied, had gone     B. had studied, went

C. has studied, goes      D. had studied, had gone

解析：“他去北京之前在上大学学习了4年”。在上海学习的动作发生在去北京之前，因此第一个空应用过去完成时。此题选B。

2. Mary said it was at least five years since he ______ a good drink.

A. enjoyed     B. was enjoying   C. had enjoyed   D. would enjoy

解析：It was +时间段+since引导的从句中用过去完成时。应选C。

3. Xiao Pei said she ______ Hainan for 3 months.

A. has been in    B. had been in   C. had been to   D. had gone to

解析：“小培说她去了海南三个月  ”。have been to和have gone to都是短暂性的动词短语。所以适应表示状态的have been in.应选B.
