题目

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：A 解析: 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。 ---We missed you at this morning’s meeting, Diana.    ---____________, but if I hadn’t had to meet a friend, I would have been there.    A. Me, too       B. I’m sorry      C. Never mind      D. Thank you
