选择题
(2009福建顺昌模拟)——We can never forget the days _______ the two astronauts in spaceship worked together and the days ________ we spent together.
A．when; which
B．which; when
C．what; that
D．on which; when
答案
答案：A
选择定语从句的关系词关键在于区别关系词在从句中作什么成分。第一个先行词the days在从句中作状语，故用when或on which；而第二个the days在从句中作spent的宾语必须用which或that。综合两个空，只能选A。
