Question

【题目】Without friends， one can't be happy although he is rich enough. As for me， I will never forget the most wonderful days________ I spent with my friends.
A.which
B.that
C.on which

Answer 1

【答案】B
【解析】句意：没有朋友，一个人尽管足够的富有也不会开心，至于我，我会永远不会忘记我和我朋友们一起度过的最精彩的日子，这里是定语从句，先行词是days，spend为及物动词，days在定语从句中作宾语，故关系词用that指物，故选B。
