Theengineerspokehighlyofthegovernment’sefforts,____heowedhissafereturn

The engineer spoke highly of the government’s efforts, ____ he owed his safe return from Libya.A.through whichB.to whichC.with whomD.for whom

B解析试题分析：句意：这位工程师高度称赞政府的努力，他把他能从利比亚安全回来归功于政府。这里是定语从句，先行词是government’s efforts，owe…to把……归功于。与从句搭配的谓语动词搭配的介词是to，故选B。考点：考查定语从句的用法。点评：本题难度适中。介词+关系词引导的定语从句是高中的难点，判断用什么介词，一要看先行词。二看与定语从句的谓语动词搭配使用的介词。需要考生平时注意介词与动词的固定搭配。即学即练：This is the factory ________we once worked.A. through which B. in which C. with which D. for what解析：B。句意：这就是我们曾经工作过的工厂。
