选择题
_______ difficulty we meet with, we must finish it on time, because the opportunity is_______ valuable．
A．Whatever; such
B．However; such
C．However; so
D．Whatever, that
答案
答案：D
此题前半句是让步状语从句， difficulty 为名词故用Whatever，因为 However 后跟形容词或副词。第二个空填that ，that 为副词，那么，用法相当于so。valuable 为形容词不能用 such修饰，因此答案选D。
