school is our home, we are all living and studying here. in order to make ourselves safe, as a student, we should obey the school rules, we should go to school on time and be never late. we should not chase each other in the hallway and in the campus. we should get on well with others and should not fight with others. we should not eat the food that goes bad and some junk food. when you have any questions to ask, you may ask the teachers for help. especially, when you meet someone asking for money, you needn't be afraid, you can report it to the teacher at once. we are required to say goodbye to bad habits and be polite to others.
