问题补充：
I’m curious to know it is has made Anne she is today.
A. what; that; what
B. what; what; who
C. that; what; who
D. that; what; who
答案：
(答案→)A. what; that; what
B. what; what; who
C. that; what; who
D. that; what; who
解析：句意：我很好奇想知道是什么使Anne成为她今天的样子。know后的宾语从句是强调句型结构，这里被强调部分是what，应是what+it is+that…结构；第三空是what引导的是宾补，what做表语；强调句型其结构是It was+被强调部分+ that+其他，判断强调句型的方法是把It was that去掉整个句子不缺成分，是成立的。这里被强调部分是what，它又是宾语从句的连词故应放在宾语从句之前。
