I’ll never forget the days we spent together in the country.
A. which
B. on which
C. when
D. on that

(答案→)A. whichB. on whichC. whenD. on that解析：句意：我将永远忘不了我们在乡下一起度过的时光。A 定语从句，which指代先行词days ，在后面的定语从句中作spent的宾语连接词的选择是看从句，we spent together in the country ：we 主语，spent谓语，缺了宾语，所以要选择连接代词 which故选A

这个问题我还想问问老师呢
