摘要:英語的過去完成時(shí)表示表示過去的過去。這個(gè)是大家在中學(xué)時(shí)期就知道的,今天,小編為同學(xué)們帶來了相當(dāng)豐富的與英語過去完成時(shí)的相關(guān)語法,一起來看看吧!

概念: 表示過去的過去,其構(gòu)成是had +過去分詞。  

一、過去完成時(shí)常用的連詞有: before, by, until, when, after, once, as soon as等。例如:

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.

二、在什么情況下使用過去完成時(shí)?

1. 在told, said, knew, heard, thought等動(dòng)詞引導(dǎo)的賓語從句中,一般用過去完成時(shí)。例如:

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

2. 狀語從句

在過去不同時(shí)間發(fā)生的兩個(gè)動(dòng)作中,發(fā)生在先,用過去完成時(shí);發(fā)生在后,用一般過去時(shí)。例如:

When the police arrived, the thieves had run away.

3. 表示意向的動(dòng)詞,如hope, wish, expect, think, intend, mean, suppose等,用過去完成時(shí)表示“原本……,未能……”。例如:

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

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(dòng)作之前,因此“忘了書”這一動(dòng)作發(fā)生在過去的過去,用過去完成時(shí)。句中when代表時(shí)間的一點(diǎn),表示在“同學(xué)們正忙于……”這一背景下, when所引導(dǎo)的動(dòng)作正在發(fā)生。因此前一句應(yīng)用過去進(jìn)行時(shí)。
