excited her parents most was that he was admitted to his dream college.
A. That
B. What
C. Which
D. It
网友回答
A. That
(答案→)B. What
C. Which
D. It
解析：考查主语从句。本题中的what引导的是主语从句what excited her parents most.连接代词what在句中作为主语。句意：最让他的父母兴奋的事情是他被梦想的大学录取了。It不能引导主语从句，that在主语从句中不能充当任何成分，只起引导作用。Which指特定范围之内的某一个。故B正确。
