do you still remember those day( ) we spend together?

问题描述:

do you still remember those day( ) we spend together?
这里( )中应填什么?我觉得是which或that 但我们老师说是when,
sorry,是those days 忘了s 还有应该是spent

应该是which或that, 因为定从中需要的是spend 宾语,而不是时间状语,因此不能用when.
相信我,没错的,是老师错了.
Do you still remember those days(which/that) we spend together?
