一、在學(xué)習(xí)英語(yǔ)語(yǔ)法中，過(guò)去完成進(jìn)行時(shí)是比較難掌握和理解的一種時(shí)態(tài)，但是，它在我們英語(yǔ)學(xué)習(xí)中占著很重要的位置，也是我們學(xué)好語(yǔ)法的一個(gè)因素，現(xiàn)在，讓我們一起來(lái)看看過(guò)去完成進(jìn)行時(shí)和過(guò)去完成時(shí)在英語(yǔ)學(xué)習(xí)應(yīng)用的主要區(qū)別：
過(guò)去完成式的形式如下：主語(yǔ)+had+過(guò)去分詞(done)
1、肯定句：主語(yǔ)+had+過(guò)去分詞+其他.
2、否定句：主語(yǔ)+had+not+過(guò)去分詞+其他.
3、一般疑問(wèn)句：Had+主語(yǔ)+過(guò)去分詞+其他?
肯定回答：Yes,主語(yǔ)+had
否定回答：No,主語(yǔ)+hadn't
4、特殊疑問(wèn)句：特殊疑問(wèn)詞或詞組+一般疑問(wèn)句（Had+主語(yǔ)+過(guò)去分詞+其他）?
5、被動(dòng)語(yǔ)態(tài)：主語(yǔ)+had（hadn't)+been+過(guò)去分詞+其他

二、一般情況下，在含有過(guò)去完成時(shí)的句子中，有一前一后兩個(gè)事情，發(fā)生在前的事情用過(guò)去完成時(shí)，發(fā)生在后的事情則用過(guò)去時(shí)。例如：
1.他到臺(tái)灣以前，曾學(xué)過(guò)中文。
He had studied Chinese before he came to Taiwan.
2.他念大學(xué)以前，曾前工作過(guò)。
He had worked before he decided to go to college.
3.我寫(xiě)這篇有關(guān)愛(ài)爾蘭的小說(shuō)以前，曾去過(guò)愛(ài)爾蘭。
I had been to Ireland before I wrote this book about Ireland's people.
4.我在上大學(xué)以前，已經(jīng)學(xué)過(guò)微積分。
I had studied calculus before I got into college.
5. 周一以前，已經(jīng)下過(guò)雪了。
It had already snowed before Monday.

三、如果我們要強(qiáng)調(diào)較早發(fā)生事件的連續(xù)性，我們可以用過(guò)去完成進(jìn)行式。過(guò)去完成進(jìn)行時(shí)和過(guò)去完成時(shí)惟一不同的地方是 had done 的地方一定要用had been doing 。以下是一些過(guò)去完成進(jìn)行式的例子：
1. I had been watching TV before you called me.
2. I had been working hard in a company for many years before I went to college.
3. He had been studying before he went to class.
4. He had been driving all day before he went to sleep.
