Question

Finding a new job as an operator was the reason _______ I moved.

A．at that

B．in which

C．on which

D．for which

Answer 1

D

试题分析：which引导的是定语从句，从句中谓语动词move是不及物动词，不需宾语，当先行词是reason时，后面又不缺主语和宾语，故可用关系词Why和for which，故选D。
点评：本题难度适中。定语从句是高中阶段的重难点之一，需要考生有分析理解复杂的句子结构的能力，能够正确理解句子的语境，熟练掌握关系词的意义及句法功能。这里Why="for" which.介词的选用要根据先行词和从句的动词的习惯搭配来确定。
即学即练：That's one good reason ______ he's your boss.
A. at that          B. in which         C. on which         D. for which
解析：D。句意：这是他为什么会成为你老板的一个重要原因。
