The students are having an English class in the classroom

问题描述:

The students are having an English class in the classroom
The students are having an English class in the_______(classroom/classrooms).这里是用哪个?
Don't eat in the classrooms.为什么这里classroom加S

第一个用classroom,因为同学们都在一个教室里上同一个课.
第二个就是泛指,所有的教室里都不能吃东西,所以用复数.
