One possible version:
Nowadays, some students would not like to live in a dorm. Instead, they rent houses outside the
school. There are advantages for both. Living in a dorm can increase friendship and cooperation
between classmates. And
of cause it is safer. A dorm is more like a society, which enables students
to learn to adapt to each other, thus preparing for the social life later. As for renting houses to live
alone , it's better for study
as you can feel free in your own room without being interrupted by others. As a result, you can have
more time and devote yourself to studying whole-heartedly. But there may appear some safety problems
as you live outside of the school.
Anyhow, as a student, I prefer living in a dorm.
