Safety is very important to everyone. Middle school students are the hope of our country, so the students' safety is becoming the focus to us all. As a middle school student, it's important for you to protect yourself from danger. First, you must obey the traffic rules when you go out; don't cross the street when the traffic lights are red; keep to the right in the street. Second, you should eat healthy food; don ’ t eat junk food; eat more fruit and vegetables; eat less meat and fewer eggs. Besides, don't hurt yourselves while playing. It's dangerous to swim in the river alone, so don ’ t go to the river by yourselves. In a word, it's important to remember these for you all.
