過(guò)去完成式的形式如下:
had + past participle
過(guò)去完成式是不能單獨(dú)用的。我們用的時(shí)候,必須有另一個(gè)事件。也就是說(shuō),假如我們有兩件事 A 和 B,兩件事都發(fā)生在過(guò)去,但 A 發(fā)生在 B 以前,A 應(yīng)該用過(guò)去完成式,B 則用過(guò)去式。以下是幾個(gè)例子:
(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.
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。占去完成進(jìn)行式和現(xiàn)在進(jìn)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.
