问题补充：

He bought some books in the bookstore and his father him a lot of money.

A. gives

B. will give

C. ought to give

D. must have done

答案：

A. gives

B. will give

C. ought to give

(答案→)D. must have done

解析：考查情态动词表示推测。句意：他买了很多的书，他的父亲肯定给了他很多的钱。父亲给他钱是在过去发生的事情，故使用“情态动词+have done”表示对过去发生的事情的推测。Must have done一定做了某事；故D正确。
