Security on Campus-- 校園安全
Nowadays the issue of security on campus in being discussed quite often. Some students have their cell phones stolen in dormitories; some sudents are knocked dowm by the quickly running bikes or cars; others fight with and hurt one another.
These phonemena are common on campus. I think there are several reasons for these. Firstly, students do not care take care of their properties. They are still yong and not careful enough. Secondly, students are very aggresive. Yes they want to be the winners in exams and contest, but they also want to be winners in quarrels and fightings. Besides, the campus guards do not carry their duties to the letter. They should regulate the traffic and direct the traffic flows in the rush hour.
Therefore, in order to have a secury campus, the whole students should be very careful about their porperties as wel as themselves. They should also mind their behaviors and act moderately. Of course the campus guards are supposed to be dovoted to the secury on campus as well. They are the school-regulation enforcement agents, so it is their duty to safeguard a safe and secure campus to help provide a good environment for the students. （4）Campus Security
　　Security issue may sound clichéd, 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?
　　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
