题目内容
I’m deeply impressed by the French teenager ___ I met on the trip..
A. what B. who C. which D. where
B
【解析】
试题分析：句意：我被在旅行中遇到的法国青少年深深的感动了。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。先行词是人，故选B。
考点：考查定语从句的用法。
