however和no matter how的区别

题目

however和no matter how的区别
It is reported that a large number of citizens in harbin enjoy swimming____
A.no matter how cold is it
B.however cold is it
C.no matter how it is cold
D.however cold it is
这题选什么,为什么,还有however和no matter how有什么相同点和不同点,是however可以引导名词性从句,而no matter how 不可以么?还有cold is it和is it cold
那这个是however引导的名词性从句，它是主语从句、宾语从句、表语从句还是同位语从句呢？
这个应该是让步状语从句吧

答案

就这题而言,我认为选D是最佳答案.no matter how 与however均可引导状语从句,no matter how 较口语化,语气较强,引导状语从句两者区别不大.需要提醒的是no matter how 一般不用来引导名词性从句,而however可以引导名词性从句.此题A、B、C三个选项的语序均有问题,只能选D.
楼下的说：however不能引导名词性从句,未免有点绝对吧.下面这句有问题吗?
However I deal with it is useless.
