问题 David, ______for months to find a job in New York, finally took a position at a local travel agency.

选项 A、struggling
B、struggled
C、having struggled
D、to struggle

答案C

解析 非谓语动词题。句子主干是David finally took a position at a local travel agency,结构完整,非谓语动词作状语。struggle的逻辑主语是David,二者之间是主动关系,排除B;A、C、D均为主动,而作状语时,having done表示比谓语动词动作先发生,根据句意“大卫花了数月找工作”,因此选择C。
