試題分析：考查虛擬語氣。本題的虛擬語氣是通過介詞without（要不是，如果沒有）表示出來的。根據(jù)句意可知是與過去事實(shí)相反的虛擬語氣，故使用“情態(tài)動(dòng)詞+have done”。Could not have done不可能做了某事；should not have done本不應(yīng)該做某事，實(shí)際上卻做了。句意：如果沒有經(jīng)濟(jì)援助，這位51歲的父親知道他不可能完成大學(xué)教育。故A正確。
點(diǎn)評(píng)：without虛擬語氣的用法：
1. 與現(xiàn)在事實(shí)相反：Without air, man couldn't exist on the earth.沒有空氣的話，人類將不能在地球上生存。謂語動(dòng)詞：would/could/might (not) do sth.
2. 與過去事實(shí)相反：Without your help, I would have failed the exam last week.沒有你幫助的話，我上周考試可能就通不過了。謂語動(dòng)詞：would/could/might (not) have done sth.
3. 與將來事實(shí)相反：Without your ticket, I wouldn't be able to go to the concert tomorrow.要是沒有你的票的話，我明天就不能去聽音樂會(huì)了。謂語動(dòng)詞：would/could/might (not) do sth.
