1. Dormitory life: College is different from high school. Dormitories occupy a lot of time in universities. In the dormitory, you can read books, play computer and eat hot pot with your roommates. Dormitory is like your second home.

2. Classroom life: The classrooms in universities are different from those in high schools. The classrooms in universities are large and their positions are not fixed. I usually sit with my roommate.

3. Community life: One of the characteristics of universities is community, and there are many community in universities. You can make many friends by choosing your favorite club to join according to your hobbies.

4. Travel: In college, there is a lot of free time. You can go for a walk in a nearby city with your roommate. Looking at the outside world, there will be less and less time after graduation.
