– Do you know of Guo Mingyi?
- Yes. He is an ordinary (普通的) worker chelps many poor children in China. We should follow his example.
A. that B. which C. whom D Whose

解析：句意：他是帮助许多穷孩子的一名普通工人，定语从句用来充当句中定语的结构，被修饰的名词叫先行词，连接主从句的是关系词。关系词分：1关系代词：who , whom , whose , which , that 。2关系副词：where,when why 等。一般的who 用于指代人的先行词，which 用来指代物的先行词，that既可指认又可指物。该句的先行词是人，引导词在从句中做主语，故选A。
