二、
过去完成时是一种相对时态,即以某一过去时间作参照,过去完成时表示的动作发生在这一过去时间的更过去,所以我们可以简单地用“过去的过去”这五个字来理解过去完成时态。如:
1. He _________more than 5,000 English words when he entered the university at the age of 15.
A. has learned B. would have learned C. learned D. had learned
【分析】答案选 D。因为上大学是过去,学了五千个英语单词是在上大学之前,即“过去的过去”,所以用过去完成时。
2. When the old man _________ to walk back to his house, the sun _________ itself behind the mountain.
A. started; had already hidden B. had started; had already hidden
C. had started; was hiding D. was starting; hid
【分析】答案选 A。根据句意,“开始回房子”发生在过去,“太阳落山”是在“开始回房子”之前,故过去的过去。
3. Father _________for London on business upon my arrival, so I didn’t see him.
A. has left B. left C. was leaving D. had left
【分析】答案选 D。根据“我没见到他”可知,“在我到达”前“父亲已经去伦敦”了,即父亲去伦敦发生在“过去的过去”,故用过去完成时。
4. The policeman’s attention was suddenly caught by a small box which _________ placed under the Minister’s car.
A. has been B. was being C. had been D. would be
【分析】答案选 C。因为这个小盒子“被放在部长车下”发生在“引起警察注意”之前,即“过去的过去”,所以用过去完成时。
5. “Hurry up! Alice and Sue are waiting for you at the school gate.” “Oh ! I thought they _________ without me.”
A. went B. are going C. have gone D. had gone
【分析】答案选D。因为thought(原以为)用的是过去时,所以他们“走了”就是“过去的过去”,故用过去完成时。
