1. 学习时间； 2. 安全； 3. 自由性； 4. 与同学交往； 5. 学习效果。
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.
