Ithink school rules is a system which ensures our self-discipline. these rules are of a great help to teachers and they help us change our life to the better. for example, we mustn't bully or take drinks and eat sweets in classroom. there are many students and parents who think that school rules are very strict. but i think they are all right. firstly, i think our school is trying to teach us that punctuality is a very important matter at school or in our society. punctuality helps us in many ways. it is an important part of etiquette and of good manners. secondly, i think our school is trying to tell us that we must always be clean and tidy. it is very good because many people are required to observe a dress code at work. in conclusion, i think there is no need to change our school rules because the many things we learn at school would help us in our future life. so, we must follow all those rules and prepare ourselves for an independent life.
