Question

I hear that _________ she is lovely she can be extremely difficult to deal with.

A. whether        B. as if             C. if               D. While

Answer

D

【解析】

试题分析：句意： 我听说尽管她很虎活泼可爱，但是可能非常难于相处。that引导一个宾语从句，宾语从句里又含有状语从句， 从句意可知应是让步状语从句，此处 While=although引导让步状语从句。再如While he was respected,he was not liked.他虽然受到尊敬，但是没有受到喜爱。A. Whether是否 B. as if好像C. if 只有D可以引导让步状语从句，故选D。  

考点:考查状语从句的用法。
