At the beginning of a speech, it is very important to grab the audiences attention and make them interested in you have to say．

A. what

B. which

C. that

D. who

答案：

(答案→)A. what

B. which

C. that

D. who

解析：句意：在演讲开始时，抓住听众的注意力，使他们对你要说的话感兴趣，是非常重要的。make them interested in sth使他们对......感兴趣，what you have to say你要说的话，what引导宾语从句，意为“......的事、话”。做从句宾语。that在宾语从句中只起引导作用；which 哪一个; who 谁指人。故选A。

考点: 考查介词宾语从句的用法。
