He still remembers the days ______ he spent with your family A.when B.where C.that D.on which

问题描述:

He still remembers the days ______ he spent with your family A.when B.where C.that D.on which
为什么选C不选A?
如何区分用when和that

He still remembers the days (that) he spent with your family.
这个that可以省略的,因为后面从句修饰days这个宾语
如果要选A,应该这样
He still remembers the time(s) when he spent with your family.
什么时间、时期time 才对应用when
