英语辩论赛，论题“住校外不好”，谁能给些论据我呀？要英语的啊，我方观点是“住校外不好”。急需ing！！

1, time problem: may not able to be punctual to classes

2, security problem: not as safe as living in campus

3, communication problem: no equal chances to get along with classmates as it is for those who live in campus

4, information problem: the same as communication problem--no equal chances to get useful academic information&materials as it is for those who live in campus
