day作先行词 1.用that或者which来引导.如:I can't forget the days that/which we spent in the park.(此时day为spent的宾语) 2.用when来引导. 如:The days are gone when we suffered so much. (分隔定语从句) 又如:I can't forger the days when we spent the holidays together. (注意此句和1中例句的区分,这里when we spent the holidays together是一起修饰the days的)大概是这样吧...供参考..
