过去完成时和过去完成进行时

过去完成进行时（Past Perfect Progressive Tense）

过去完成式的基本结构如下：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。

1

It had already snowed before Monday.

（6） 警察到来之前，小偷已经跑了。

When the police arrived, the thieves had already run away.

（7） 到那时，他的家人已经有半年没有他的消息了。

Until then, his family hadn’t heard from him for 6 months.

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.

过去完成时

1） 概念：表示过去的过去
