题型:不详难度:来源:
He tried his best to solve the problem, _______difficult it was.
A.no matterB.no matter howC.whateverD.although

答案
B
解析

试题分析:考查让步状语从句。No matter +特殊疑问词引导让步状语从句,意为:无论…;意为后面接形容词difficult,所以使用how.而不是what.句意:无论问题有多难,他都全力以赴地解决它。故B正确。
点评:no matter特殊疑问词只能引导让步状语从句;特殊疑问词ever既可引导时间状语从句也可以引导名词性从句。
