Question

—Could you please tell me ________ that prevents her from being happy?

—She has taken the driving test three times but hasn’t passed yet.

A. it is what B. what it is

C. how it is D. it is how

Answer 1

B

【解析】

试题分析：句意：---你能告诉我究竟是什么阻止她快乐起来吗？----她已经参加了三次驾驶考试，但是还是没有通过。强调句的陈述结构是it is+被强调部分+that，特殊疑问句结构是：特殊疑问词+is it +that。把It is··· that去掉，则很容易地看出what引导的宾语从句，而且what在从句prevents her from being as happy as before中充当主语。因为tell后是宾语从句，因此要用陈述语序，故选B。

考点：考查强调句的用法。
