关于next Sunday前加不加 the.

问题描述:

关于next Sunday前加不加 the.
我看见这样一句话:LiMei said that she was going to visit her grandma in the cointry the next Sunday.
不加the 行不 这为什么要加 the

这里的THE是特指,
李梅说她下个周日要去乡下看她奶奶.
我觉得这句话貌似有点不通顺,
LiMei said that she was going to visit her grandma in the country,in the next Sunday.
加个IN
