　　Campus Security

　　Security issue may sound cliched, but when it comes to the campus security, we have to take it seriously.Nearly every day, there are reports to the security office on campus that valuable things are stolen away.A surrounding with stealing, mugging can’t be worse for studying.In such cases, what measures should be taken to improve the campus security?

　　Above all, we students should strengthen our security awareness.Once we smell out something unusual, we should report it to the campus guard immediately.In addition, 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.

　　As to me, campus security will be improved as long as efforts are made on campus.Therefore colleges and universities should exert their best efforts to make everyone on campus safe and sound.
