有好多种说法：最常见的是in residence
其他的：
1.live on campus
I don't have to live on campus.
我不必住宿.
Did you have to live on campus last year?
去年你必须住宿吗?
2.in residence
Students must remain in residence during term.
学生於学期中必须住宿.
所以最地道的表达是the life in residence
dormitory life也说得通,但是life用dormitory（n.)形容似乎不太好,用名词修饰名词的只有常见的诸如sports meeting之类的,我也不确定dormitory life是不是对,但是the life in residence我是绝对确定的.
