I will never forget the days that we spent together in the country.

问题描述:

I will never forget the days that we spent together in the country.
I will never forget the days when we worked together in the country
为什么差不多的句子,为什么一个that,一个when?

定语从句关键要看关系词替代先行词在从句中充当的成分.第一个句子中,spent 是一个及物动词,所以the days 在从句中做的是宾语.that/which 均可,也可以省略.而第二题中,work 是不及物动词,所以the days 做的是时间状语.
