题目分析:考查虚拟语气。本题的虚拟语气是通过介词without(要不是,如果没有)表示出来的。根据句意可知是与过去事实相反的虚拟语气,故使用“情态动词+have done”。Could not have done不可能做了某事;should not have done本不应该做某事,实际上却做了。句意:如果没有经济援助,这位51岁的父亲知道他不可能完成大学教育。故A正确。
点评:without虚拟语气的用法:
1. 与现在事实相反:Without air, man couldn't exist on the earth.没有空气的话,人类将不能在地球上生存。谓语动词:would/could/might (not) do sth.
2. 与过去事实相反:Without your help, I would have failed the exam last week.没有你帮助的话,我上周考试可能就通不过了。谓语动词:would/could/might (not) have done sth.
3. 与将来事实相反:Without your ticket, I wouldn't be able to go to the concert tomorrow.要是没有你的票的话,我明天就不能去听音乐会了。谓语动词:would/could/might (not) do sth.
