The engineer ______ my father works is about 50 years old.

A. to whom

B. on whom

C. with which

D. with whom

题目解答

答案

D. with whom

解析

本题考查定语从句中介词与关系代词的搭配。解题核心在于：

  1. 确定先行词：句子中的先行词是engineer，指人；
  2. 还原省略的介词短语：原句中my father works需还原为my father works with the engineer，明确介词with的存在；
  3. 选择正确搭配：关系代词whom需与介词with搭配，构成with whom。

步骤解析

  1. 分析句子结构
    原句为定语从句修饰engineer，从句中my father works需补充完整逻辑关系。
    关键逻辑：父亲的工作对象是工程师，即my father works with the engineer。

  2. 确定介词与关系代词

    • 先行词engineer是人，需用whom指代；
    • 原句逻辑中work的介词是with，因此搭配为with whom。

  3. 排除错误选项

    • A. to whom：介词to错误，逻辑不符；
    • B. on whom：介词on无意义；
    • C. with which：which指代物，但engineer是人。
