Question

 (2011年重庆诊断)—I don’t know________makes her different from others.

—Honesty，I think.

A．how is it that                              B．how it is that

C．what is it that                       D．what it is that

Answer 1

解析：选D。考查特殊句式。上一句的意思是“我不知道是什么让她与众不同”，what it is that makes her different from others是know的宾语从句，因此要用陈述语序。从句是一个强调句，被强调部分是主语what。
