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. 作者: 蜡笔小新 时间: 2012-4-14 10:51 作者: 青野 时间: 2012-4-26 17:23
