题目内容
【题目】It is interesting to know that even stones and seashells can ________ things by ancient people.
A.use to buyingB.use to buy
C.be used to buyingD.be used to buy
【答案】D
【解析】
句意:知道古人甚至可以用石头和贝壳来买东西是非常有趣的。
考查被动语态和不定式用法。从句主语stones and seashells,与谓语动词use之间是被动关系,表示“被用于”,因此用be used;be used to do sth.表示“用于做某事”,不定式作宾语。故选D。
