General rules:
1) 如果我们正在说的已经是过去的事,要说到比这再早一些时候发生的事情,就用过去完成时。例如:
He wasn't exactly a stranger — I had met him once before.
I could see from his face that he had received bad news.
I explained that I had forgotten my keys.
注意:只有存在比所说的过去还要早的情况,才能用过去完成时。谈论前不久发生的事情,不能用过去完成时。如下面两句中的一般过去时不能用过去完成时替换:
I left some photos to be developed. Are they ready yet?
General Cary, who commanded a parachute regiment for many years, is now living in retirement.
2) 过去完成时常常用在间接引语里,放在said, told, asked, explained, thought, wondered 等过去式动词的后面, 指在谈话等之前已经发生了的事情。如:
I told them that I had done enough work for one day.
She wondered who had left the door open.
I thought I'd sent the cheque a week before.
