When students are in school, they think they are so safe and don’t need to watch out, while recently, many incidents were reported happening in the school, this school is no longer the place that students don’t need to take care of. School security problem happens all the time, students should learn to protect themselves. Lately, it has been reported that a rich boy drove an expensive car, at a fast speed, ran across the school road, hit a student and the student died in the car accident. This is so terrible, the school is always thought to be a safe place for students, they never think that the accidents will happen there. Now as more and more schools are open to the outsiders, people can go to the school anytime, anywhere. Bad guys are invisible, they can do what they want in the school. So students must take care of themselves in the school.
