基本用法
(1)表示在過去某一時刻或動作以前完成了的動作,也可以說過去的時間關於過去的動作.即“過去的過去”.可以用by,before等介詞短語或一個時間狀語從句來表示,也可以用一個表示過去的動作來表示,還可能通過上下文來表示.例如：By nine o’clock last night,we had gotten 200 pictures from the spaceship.到昨晚9點鐘,我們已經收到200 張飛船發來的圖片.
(2)表示由過去的某一時刻開始,一直延續到過去另一時間的動作或狀態,常和for,since構成的時間狀語連用.例如：I had been at the bus stop for 20 minutes when a bus finally came.當車來的時候,我在車站已等了20分鐘 said he had worked in that factory since 1949.他說自從1949年以來他就在那家工廠工作.
(3)敘述過去發生的事情,在已敘述了過去發生的事情後,反過來追述或補述以前發生的動作時,常使用過去完成時.例如：h died had been a good friend of mine.史密斯先生昨天去世了.他以前是我的好友.I didn’t know a thing about the verbs,for I had not studied my lesson.我對動詞一無所知,因爲我沒有好好學習功課.
(4)在含有定語從句的主從複合句中,如果敘述的是過去的事,先發生的動作常用過去完成時.例如：I returned the book that I had borrowed.我已歸還了我借的書 found the key that she had lost.她丟失的鑰匙找到了.
(5)過去完成時常常用在told,said,knew,heard,thought等動詞後的賓語從句(或間接引語)中,這時從句中的動作發生在主句表示的過去的動作之前.例如：He said that he had known her well.他說他很熟悉她.I thought I had sent the letter a week before.我認爲我一星期前就把信寄出去了.
(6) 狀語從句：在過去不同時間發生的兩個動作中,發生在前,用過去完成時;發生在後,用一般過去時.如when,before,after,as soon as,till/until引導的 例如：When I woke up,it had already stopped raining.我醒來時雨已停了 didn’t go to bed until she had finished her work.她直到把工作做完之後才睡覺.注意：如果兩個動作緊接着發生,則常常不用過去完成時,特別是在包含before和after的複合句中,因爲 這 時從句的動作和主句的動作發生的先後順序已經非常明確,這時可以用一般過去時代替過去完成時.例如：After he arrived in England,Marx worked hard to improve his English.馬克思到達英格蘭之後,努力提高他的英語水平.
(7)動詞think,want,hope,mean,plan,intend等用過去完成時來表示過去未曾實現的想法,希望,打算或意圖等.例如：They had wanted to help but could not get there in time.他們本來打算去幫忙,但沒有及時趕到那裏 had hoped to be able to come and see you .我們本來希望能來看看你.
(8)過去完成時還可用在hardly…when…,no sooner…than…,It was the first (second,etc) time (that)…等固定句型中.例如：Hardly had he begun to speak when the audience interrupted him.他剛開始演講,聽衆就打斷了他 sooner had he arrived than he went away again.他剛到就又走了 was the third time that he had been out of work that year.這是他那一年第三次失業了.
時間狀語 before,when,after,by+,until,once,had no sooner……than,yet,already等.
