1. 定義:表示在過(guò)去某一時(shí)間或動(dòng)作之前已經(jīng)發(fā)生或完成了的動(dòng)作或狀態(tài)。
2. 構(gòu)成:had+過(guò)去分詞
注意:had是助動(dòng)詞

(2)常用時(shí)間狀語(yǔ):
1) by +過(guò)去時(shí)間點(diǎn)或句子;
2) before+過(guò)去時(shí)間點(diǎn)或句子;
3) when+句子。
3. 用法及標(biāo)志性詞:
① 過(guò)去完成時(shí)表示在過(guò)去某一時(shí)間或動(dòng)作以前已經(jīng)完成了的動(dòng)作。這個(gè)過(guò)去的時(shí)間常用by,before等介詞短語(yǔ)或一個(gè)時(shí)間狀語(yǔ)從句表示,也可以暗含在上下文中。 如:
I had finished my homework before supper.
我在晚飯前就把作業(yè)做完了。

旱了好幾個(gè)月之后,昨天下雨了。
注意:
① 在包含before和after的復(fù)合句中,因?yàn)閺木鋭?dòng)作和主句動(dòng)作發(fā)生的先后順序已經(jīng)非常明確,可以用一般過(guò)去時(shí)代替過(guò)去完成時(shí)。

在我到達(dá)車站之前,列車已經(jīng)開了。
After he(had)arrived in England, Marx worked hard to improve his English.

②過(guò)去完成時(shí)還可表示過(guò)去某一時(shí)刻之前發(fā)生的動(dòng)作或狀態(tài)持續(xù)到過(guò)去某個(gè)時(shí)間或還要持續(xù)下去,
常與for,since等詞連用。如:

比較:
by the end of + 將來(lái)時(shí)間點(diǎn),表示將來(lái), 意為“,到...為止”.通常與一般將來(lái)時(shí)連用.如:
By the end of 2030, I will go to Hainan to spend my holiday.
到2030年底的時(shí)候, 我要去海南度假.
By the end of last month I had spent all my money
到上個(gè)月底時(shí),我已經(jīng)花光了自己所有的錢。
③敘述過(guò)去發(fā)生的事情之后,反過(guò)來(lái)追述或補(bǔ)述以前發(fā)生的動(dòng)作時(shí),常使用過(guò)去完成時(shí)。如:
Tom flew home, but his father had already died.
湯姆乘飛機(jī)回家,他的父親卻已經(jīng)去世了。
Tom died yesterday. He had been a good friend of mine.
湯姆昨天去世了。他以前是我的好友。
④在含有定語(yǔ)從句的主從復(fù)合句中,如果敘述的是過(guò)去的事,先發(fā)生的動(dòng)作常用過(guò)去完成時(shí)。如:
I returned the book that I had borrowed.
我已歸還了我借的書。
She found the key that she had lost.
她丟失的鑰匙找到了。
⑤過(guò)去完成時(shí)用在told, said, knew, heard, thought等動(dòng)詞后的賓語(yǔ)從句中,這時(shí)從句的動(dòng)作發(fā)生在主句的過(guò)去的動(dòng)作之前。如:
He said that he had known her well.
他說(shuō)他很熟悉她。
I thought I had sent the letter a week before.
我認(rèn)為我一星期前就把信寄出去了。
4. 表示意向的動(dòng)詞,如hope,wish, expect, think, intend, mean, suppose等,用過(guò)去完成時(shí)表示“原本……,未能……”。如:
We had hoped that you would come, but you didn’t.
我們本希望你能來(lái),但是你沒(méi)來(lái)。
The terrorists had planned to hijack the airplane, but they were arrested by the agents.
恐怖分子本打算要劫機(jī),但是他們被情報(bào)人員逮捕了。(企圖失敗)
5. 過(guò)去完成時(shí)與一般過(guò)去時(shí)的區(qū)別:
① 過(guò)去完成時(shí)與一般過(guò)去時(shí)都可以和確定的過(guò)去時(shí)間狀語(yǔ)連用,但意思有明顯區(qū)別。試比較:
He had finished his homework by eight.
他到八點(diǎn)鐘的時(shí)候已經(jīng)完成家庭作業(yè)了。
He finished his homework at eight.
他在八點(diǎn)鐘完成了家庭作業(yè)。
②用在賓語(yǔ)從句中,主句謂語(yǔ)為一般過(guò)去時(shí)的賓語(yǔ)從句中,既可用一般過(guò)去時(shí),也可用過(guò)去完成時(shí)。但兩種時(shí)態(tài)的意義明顯不同。試比較:
He said he was a soldier.
他說(shuō)他是位軍人。
He said he had been a soldier.
他說(shuō)他曾當(dāng)過(guò)兵。
