选择题
_________ difficult the task may be, we must finish it on time, because we can’t meet such a precious opportunity _______ we have expected.
A．Whatever; that
B．However; as
C．However; that
D．Whatever, which
答案
答案：B
句意：无论这个工作有多困难，我们必须如期完成，因为我们不可能再遇到正如我们期望的这样的好机会。However =" No" matter how修饰形容词 difficult, 而在定语从句中先行词有such 修饰，关系词用as，因此答案B是正确的。
