【题目】I'll never forget the days________I worked hard at my lessons in Senior Three，________changed my whole life.
A. that；which B. when；which
C. which；when D. when；that
在线课程【答案】B
【解析】考查定语从句。句意：我永远也不会忘记我高三时努力学习的日子，它改变了我的人生。第一个空前的the days是先行词，后面的定语从句缺少时间状语，故用关系副词when。逗号之后为非限定性定语从句，从句中缺少的是主语，故选用关系代词which，答案为B。
