【—過去完成時語法輔導】以下是對英語語法過去完成時內(nèi)容的講解,希望同學們很好的掌握下面的內(nèi)容。
過去完成時
1) 概念:表示過去的過去
--------------------------> 其構(gòu)成是had +過去分詞構(gòu)成。 那時以前 那時 現(xiàn)在
2) 用法
a. 在told, said, knew, heard, thought等動詞后的賓語從句。例如:
She said (that)she had never been to Paris. 她告訴我她曾去過巴黎。
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。例如:
When the police arrived, the thieves had run away. 警察到達時,小偷們早就跑了。
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…"。例如:
We had hoped that you would come, but you didn't. 那時我們希望你能來,但是你沒有來。
3) 過去完成時的時間狀語before, by, until , when, after, once, as soon
as。例如:

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。因此前一句應用過去進行時。
注意: had hardly… when 還沒等…… 就……。例如:
I had hardly opened the door when I he hit me. 我剛打開門,他就打了我。
had no sooner…than 剛…… 就……。例如:
He had no sooner bought the car than he sold it. 他剛買了這輛車,轉(zhuǎn)眼又賣了。
以上對英語過去完成時的語法知識講解,相信同學們都能很好的掌握了吧,希望同學們考試成功。
