過去完成進(jìn)行時(shí)表示在過去較早的時(shí)間內(nèi)進(jìn)行的動(dòng)作，并對(duì)過去某一刻的動(dòng)作或狀態(tài)產(chǎn)生結(jié)果。過去完成進(jìn)行時(shí)由had been加現(xiàn)在分詞構(gòu)成。

1.1 過去完成進(jìn)行時(shí)的構(gòu)成
肯定句：主語 + had been + 現(xiàn)在分詞...
疑問句：疑問代詞/疑問副詞 + had + 主語 + been + 現(xiàn)在分詞...?

1.2 過去完成進(jìn)行時(shí)的肯定句
句型：主語 + had been + 現(xiàn)在分詞...
過去完成進(jìn)行時(shí)的肯定句由“助動(dòng)詞had + been（been為be動(dòng)詞的過去分詞） + 現(xiàn)在分詞”構(gòu)成：
She was tired. She had been working all day.她很累了。她整天都在工作。
When I first met Jane，she had been working in that school for10years.我第一次遇到簡(jiǎn)的時(shí)候，她已在那所學(xué)校干了10年了。

1.3 過去完成進(jìn)行時(shí)的特殊疑問句
句型：疑問代詞/疑問副詞 + had + 主語 + been + 現(xiàn)在分詞...?
過去完成進(jìn)行時(shí)的特殊疑問句是將疑問代詞/疑問副詞置于助動(dòng)詞had之前（had的第一個(gè)字母無需大寫），和一般疑問句差不多；這種語序是倒裝語序。就主語提問時(shí)，將疑問代詞或帶有疑問限定詞的名詞詞組置于助動(dòng)詞had之前，在句尾加問號(hào)；這種語序是陳述句語序：
How long had it been raining before you shut the window? 你關(guān)窗戶之前雨下了多久了?

1.4 過去完成進(jìn)行時(shí)的用法
1.表示過去某時(shí)以前持續(xù)的動(dòng)作
過去完成進(jìn)行時(shí)的主要特點(diǎn)與現(xiàn)在完成進(jìn)行時(shí)的主要特點(diǎn)基本相似，只是時(shí)間推移到了過去：
I was tired that day，because I had been working all day.我那天累了，我干了一整天的活。
His eyes were red. It was obvious that he had been working too hard.他眼睛紅了，顯然是前一段時(shí)間他工作太緊張了。
過去完成進(jìn)行時(shí)表示一個(gè)動(dòng)作從過去某時(shí)開始，一直延續(xù)到另一個(gè)過去時(shí)刻，到那個(gè)時(shí)刻，該動(dòng)作可能剛剛終止，也可能還在繼續(xù)：
At last they got the information they had been expecting.最后他們得到了盼望得到的信息。（剛剛終止）
When I got home，I found that Jack had been working on his home-work.當(dāng)我回家時(shí)，發(fā)現(xiàn)杰克在做作業(yè)。（可能還在繼續(xù)）
過去完成進(jìn)行時(shí)表示一個(gè)動(dòng)作已經(jīng)結(jié)束，但其結(jié)果仍影響到過去某一時(shí)刻：
It had been snowing for several days. The ground was all covered with snow.接連下了幾天的雪，地上到處是積雪。
某些表示持續(xù)動(dòng)作的動(dòng)詞如work（工作），teach（教授），study（學(xué)習(xí)），sing（演唱）等，在與表示一段時(shí)間的狀語連用時(shí)，可用過去完成進(jìn)行時(shí)和過去完成時(shí)，表示一個(gè)動(dòng)作一直延續(xù)到過去某一時(shí)刻，但前者更強(qiáng)調(diào)動(dòng)作的持續(xù)性和不間斷性：
I'd been studying for2hours when he called.他打電話來的時(shí)候，我持續(xù)學(xué)習(xí)了兩個(gè)小時(shí)。
I'd studied for2hours when he called.他打電話來的時(shí)候，我已經(jīng)學(xué)習(xí)了兩個(gè)小時(shí)了。

2.用于得出結(jié)論
過去完成進(jìn)行時(shí)可以表示根據(jù)直接或間接的證據(jù)而得出結(jié)論：
His eyes were red. It was obvious that he had been working too hard.他的眼睛紅了，顯然前一段時(shí)間他工作太緊張了。

3.用于間接引語
They said they had been having a match with Class One.他們說剛才和1班進(jìn)行了一場(chǎng)比賽。
這個(gè)時(shí)態(tài)的用法可以下圖表示：
