語法 | 過去完成時用法解析
英語的過去完成時表示表示過去的過去。這個是大家在中學時期就知道的，今天，小編爲同學們帶來了相當豐富的與英語過去完成時的相關語法，一起來看看吧！
1、表示在過去某一時間或動作之前已經發生或完成的動作。 他表示的時間是"過去 的過去 "常與by last year, by the time of yesterday,等連用。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 從過去某一時間開始一直延續到過去另一時間的動作或狀態。常與for (後跟段時間)或since (後跟點時間)等連用.如:
She had worked in this school since it opened 25 years ago.
例題解析：舉一反三，學的更輕鬆！
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學學習了4年 "。在上海學習的動作發生在去北京之前，因此第一個空應用過去完成時。此題選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 + 時間段+since 引導的從句中用過去完成時。應選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："小培說她去了海南三個月 "。have been to 和have gone to 都是短暫性的動詞短語。所以適應表示狀態的have been in. 應選B.
