Question

This is the best way ______ I have thought of ______ the problem.

A．that; solving	B．in which; solving
C．which; to solve	D．/; to solve

Answer

D

【解析】考察定语从句和特殊用法。定语从句I have thought of修饰先行词the best way，I前面省略了that.第二空是特殊用法：the way to do sth=" the" way of doing sth做某事的方法。故D正确。句意：这是我想起来的解决问题的最好方法。
