過(guò)去完成進(jìn)行時(shí)的結(jié)構(gòu)：had been +動(dòng)詞ing。表示相對(duì)過(guò)去的某個(gè)時(shí)刻來(lái)說(shuō)已經(jīng)對(duì)現(xiàn)在有直接影響并且還在進(jìn)行的動(dòng)作。很少用在否定句中，多以過(guò)去完成時(shí)代替。

特別含義?
尚未完成：
He had been writing the novel．（他沒(méi)有完成它）
企圖：
He had been studying the meaning of this proverb．（他一直在努力學(xué)習(xí)它）
未得結(jié)果：
We had been studying what our enemy had said．（但我們不能理解）
最近情況：
He had been quarrelling with his wife．（近來(lái)）
情緒：
What had he been doing？（不耐煩）
特點(diǎn)編輯
這種時(shí)態(tài)很少用在否定句中，而多以過(guò)去完成時(shí)代替：
　　He had not practised English for many years．（普通說(shuō)法）
　　He had not been practising English for many years．（少見(jiàn)）
這種時(shí)態(tài)還可用在said，supposed等引起的間接引語(yǔ)中，代替現(xiàn)在完成進(jìn)行時(shí)：
　　He said:“I have been speaking to John."= He said that he had been speaking to John．
　　He thought:“She was watching me when I passed．”= He thought that she had been watching him when he had passed．
過(guò)去完成進(jìn)行時(shí)經(jīng)常與現(xiàn)在完成進(jìn)行時(shí)混淆。
現(xiàn)在完成進(jìn)行時(shí) (The present perfect progressive) 由 have/has been +-ing 分詞構(gòu)成；
　　過(guò)去完成進(jìn)行時(shí)（ The past perfect progressive tenses ）由 had been +-ing 分詞構(gòu)成．
現(xiàn)在/過(guò)去完成進(jìn)行時(shí)的用法：
A. 在某段時(shí)間內(nèi)一直進(jìn)行的動(dòng)作用現(xiàn)在完成進(jìn)行時(shí)來(lái)強(qiáng)調(diào)動(dòng)作在某段時(shí)間里的持續(xù)性．動(dòng)作通常有"現(xiàn)在"的結(jié)果，要根據(jù)上下文來(lái)確定到"現(xiàn)在"為止，動(dòng)作是否還在繼續(xù)進(jìn)行．同樣，過(guò)去完成進(jìn)行時(shí)表示在過(guò)去更早時(shí)間內(nèi)進(jìn)行的動(dòng)作,并對(duì)過(guò)去某一時(shí)刻產(chǎn)生結(jié)果。
B.表示重復(fù)動(dòng)作的現(xiàn)在/過(guò)去完成進(jìn)行時(shí)
我們也可以用完成進(jìn)行時(shí)形式來(lái)表示現(xiàn)在或過(guò)去經(jīng)常重復(fù)的動(dòng)作
注意：過(guò)去完成進(jìn)行時(shí)和過(guò)去完成時(shí)類似，需要有過(guò)去這一時(shí)間段
用法編輯
表示過(guò)去某一時(shí)間之前一直進(jìn)行的動(dòng)作。
　　過(guò)去完成進(jìn)行時(shí)表示動(dòng)作在過(guò)去某一時(shí)間之前開(kāi)始，一直延續(xù)到這一過(guò)去時(shí)間。和過(guò)去完成時(shí)一樣，過(guò)去完成進(jìn)行時(shí)也必須以一過(guò)去時(shí)間為前提。
　　I had been looking for it for days before I found it.這東西我找了好多天才找著的。
　　They had only been waiting for the bus a few moments when it came.他們只等了一會(huì)兒車(chē)就來(lái)了。

　　He had been mentioning your name to me.他過(guò)去多次向我提到過(guò)你的名字。

接具有“突然”之意when句。

時(shí)態(tài)比較編輯
過(guò)去完成進(jìn)行時(shí)與過(guò)去完成時(shí)的用法很相近，它通常表示某個(gè)過(guò)去正在進(jìn)行的動(dòng)作或狀態(tài)，持續(xù)到過(guò)去某個(gè)時(shí)刻，還未完成，一直持續(xù)到之后才結(jié)束
He had been waiting for two weeks． He was still waiting．（有一個(gè)表示一段時(shí)間的狀語(yǔ)）
他已經(jīng)等了兩個(gè)星期。他還在等。
Up to that time he had been translating those books．直到那時(shí)他一直在翻譯這些書(shū)。
He had been writing the letter till two o'clock．他一直在寫(xiě)那封信到兩點(diǎn)鐘。
He was thirty years old．He had been gambling since he was ten．（He was still gambling at thirty．）
他三十歲。他從十歲開(kāi)始就一直在賭博。（三十歲的他仍然賭博。）
He had been standing there in the sun．（沒(méi)有時(shí)間狀語(yǔ)）
他一直站在太陽(yáng)底下。
He had been thinking about his marriage．（沒(méi)有時(shí)間狀語(yǔ)）
他一直在對(duì)他的婚姻思考。
不過(guò)這種時(shí)態(tài)并不一定表示這個(gè)過(guò)去動(dòng)作將持續(xù)下去：
He came back at seven．He had been waiting for her two hours．（At seven he did not wait any more．）
他在七點(diǎn)回來(lái)了。他等了她兩個(gè)小時(shí)。（在七點(diǎn)時(shí)，他不想再等了。）
He stopped swimming．He had been swimming for the last three hours．他停止了游泳。他已經(jīng)在過(guò)去的三小時(shí)內(nèi)游泳。
