英語過去完成時的語法和例題

  過去完成時是表示過去的過去,通常是用had +過去分詞構(gòu)成了它基本的結(jié)構(gòu)。

英語過去完成時的語法和例題

  1)概念:表示過去的過去,其構(gòu)成是had +過去分詞構(gòu)成。

  2)用法

  a. 在told, said, knew, heard, thought等動詞后的賓語從句。

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

  b. 狀語從句

  在過去不同時間發(fā)生的兩個動作中,發(fā)生在先,用過去完成時;發(fā)生在后,用一般過去時。

  When the police arrived, the thieves had run away.

  c. 表示意向的動詞,如hope, wish, expect, think, intend, mean, suppose等,用過去完成時表示"原本…,未能…"

  We had hoped that you would come, but you didn't.

  3)過去完成時的時間狀語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.

  典型例題

  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. "把書忘在辦公室"發(fā)生在"去取書"這一過去的動作之前,因此"忘了書"這一動作發(fā)生在過去的過去,用過去完成時。句中when表示的是時間的一點,表示在"同學們正忙于……"這一背景下,when所引導的動作發(fā)生。因此前一句應(yīng)用過去進行時。

  注意:

  had no … when 還沒等…… 就……

  had no sooner… than 剛…… 就……

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