问题
选择题
_____ you may have, you should gather your courage to face the challenge.
A．However serious a problem.
B．What a serious problem.
C．However a serious problem.
D．What serious a problem.
答案
答案：A
题目分析：让步状语跟感叹句的混合。句意：无论你有多么严重的问题，你都要鼓起勇气去面对挑战。However+adj+主+谓；whatever+n+主+谓语。首先明白这是个让步状语从句,what不可引导,故不选B。
点评：要记忆however和whatever在引导让步状语从句时的区别,并多做这方面的练习加以巩固。
