In recent years many universities have built up their branch campuses in suburban areas. Now it is very difficult to find a university without a branch campus. Some of them even have more than on branch campus. There are two main reasons behind the phenomenon. Firstly, it is enrollment expansion of universities that focuses universities to build branch campuses. As more and more freshmen are admitted, the original facilities including calssrooms, apartments, dining halls, laboratories, libraries are not enough any more. Secondly, the quite environment in suburban areas is more suitable for students to study. So most of branch areas have been located in suburban areas. As college student, I think, it is necessary for the university to build up a branch campus. However, the building of branch campuses brings some problems. The students in some branch campuses cannot enjoy good enough facilities and teachers due to limited resources. Therefore, the university should take a full account before it decides to build up a branch campus.
