Question

--Friends, we’ll graduate from middle school. We shouldn’t forget the days     we spent with classmates.
--Yeah, without friends, one can’t be happy.
A. that            B. when          C who

Answer 1

A

试题分析：本句中先行词the days为下文逻辑宾语，指物，故引导词用that，选A。
点评：定语从句引导词的用法比较复杂,其关键就是根据先行词的不同选择不同的引导词.并注意作介词宾语的引导词只能使用宾格形式.that不能用于非限制性定语从句中.
