On the one hand, we students should strengthen our security awareness. Once we smell out something unusual, we should report it to the campus guard immediately. On the other hand, more equipment such as monitors should be installed on campus so as to detect crimes as soon as possible. Besides, a proper amount of security guards should be arranged to patrol the campus。

　　In my opinion, campus security will be improved as long as efforts are made on campus. Therefore colleges and universities should try their best to make everyone on campus safe and sound。(总结观点段)
