  【—过去完成时】过去完成时是表示过去的过去,通常是用had +过去分词构成了它基本的结构。

  1)概念:表示过去的过去,其构成是had +过去分词构成。

  2)用法

  a. 在told, said, knew, heard, thought等动词后的宾语从句。

  She said (that) she had never been to Paris.

  b. 状语从句

  在过去不同时间发生的两个动作中,发生在先,用过去完成时;发生在后,用一般过去时。

  When the police arrived, the thieves had run away.

  c. 表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…"

  3)过去完成时的时间状语before, by, until , when, after, once, as soon as。

  He said that he had learned some English before.

  By the time he was twelve, Edison had began to make a living by himself.

  Tom was disappointed that most of the guests had left when he arrived at the party.

  典型例题

  The students ___ busily when Miss Brown went to get a book she ___ in the office.

  A. had written, left B,were writing, has left  C. had written, had left D. were writing, had left

  答案D. "把书忘在办公室"发生在"去取书"这一过去的动作之前,因此"忘了书"这一动作发生在过去的过去,用过去完成时。句中when表示的是时间的一点,表示在"同学们正忙于……"这一背景下,when所引导的动作发生。因此前一句应用过去进行时。

  注意:

  had no … when     还没等…… 就……

  had no sooner… than  刚…… 就……

  He had no sooner bought the car than he sold it.

  这一章对过去完成时,介绍的还是相当的全面的,不论是含义还是用法都有介绍,包括典型例题的解答。
