______, he always tries his best to solve it.
A．Though difficult the problem is
B．However difficult the problem is
C．Though difficult is the problem
D．However the problem is difficult

参考答案

正确答案：B
解析：当though引导状语从句时，它后面的部分应当是正常的语序，不需要使用倒装结构，所以说，选项A和C都是错误的。此外，当however引导状语从句时，它所修饰的形容词或副词应该紧随其后出现，这样看来的话，选项D也要被排除掉。因此，只有选项B才是唯一正确的。
