选择题
I shall never forget the days ______ I stayed in Africa, ________ has brought me a lot of advantages.
A．that; which
B．when; which
C．when; that
D．which; that
答案
答案：B
考查定语从句的关系词。先行词days在定从______ I stayed in Africa中作时间状语，所以用when引导，排除A,D；定从________ has brought me a lot of advantages的先行词是前面整个句子，且是非限制性定从，要用which引导。所以选B。
