选择题
—Time is limited. I have to finish this tonight.
—But it’s midnight now and you should have a sleep ______ much work you have to do.
A．however
B．no matter
C．although
D．whatever
答案
答案：A
题目分析：考查让步状语从句：句意为：无论有多少活要做，你都应该睡一觉。用however(相当于no matter how)修饰much work。 although也可以引导让步状语从句，但其后应跟句子的主语，且不用倒装语序。Whatever修饰的是名词，选A。
