英语过去完成时和过去完成进行时的区别
过去完成式
过去完成式的形式如下：
had + past participle
过去完成式是不能单独用的。我们用的时候，必须有另一个事件。也就是说，假如我们有两件事
A
和
B
，两件事都发生在过去，但
A
发生在
B
以前，
A
应该用过去完成式，
B
则用过去式。以下是几个例子：
(1)
他到台湾以前，曾学过中文。
He had studied Chinese before he came to Taiwan.
(2)
他念大学以前，曾前工作过。
He had worked before he decided to go to college.
(3)
我写这篇有关爱尔兰的小说以前，曾去过爱尔兰。
I had been to Ireland before I wrote this book about Ireland's people.
(4)
我在上大学以前，已经学过微积分。
I had studied calculus before I got into college.
(5)
周一以前，已经下过雪了。
It had already snowed before Monday.
如果 我们要强调较早发生事件的连续性，我们可以用过去完成进行式。占去完成进行式和现在进行式惟一不同的地方是
verb to have
的地方一定要用
had
。以下是一些过去完成进行式的例子：
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.
