Nowadays, some students would not like to live in a dormitory. Instead of, they rent houses outside the school. There are advantages for them both. Live in a dormitory can increase friendship and cooperation among classmates, and of course it is safer．However, a dormitory is more like a society, where enables students to learn to get along well with each other，thus preparing the social life later. As for renting houses to live alone, it’s better for your study as you can feel freely in your own room with being interrupted by others. Absorbing in your study，you can have a plenty of time to devote yourself to review your lessons wholeheartedly. But there may appears a few safety problems as you live outside the school. Anyhow as a student, I prefer living in a dormitory.
