過去完成時(shí)
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(shí)以前 那時(shí) 現(xiàn)在
2） 用法
a. 在told, said, knew, heard, thought等動(dòng)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(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：

c. 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：

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表示的是時(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)作發(fā)生。因此前一句應(yīng)用過去進(jìn)行時(shí)。
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。
