In our school, some students do not behave well at all. As is shown in the following pictures, some spit as well as litter everywhere whenever they want. Some cheat in exams while some jump the queue when they are waiting to get their meals in the dining-hall. Some students even quarrel in public or fight against each other. All the above behavior is of no good to building a friendly and harmonious society.
As a citizen in this civilized society, we should form good habits and develop a sense of responsibility. We must know that every bit of the improvement of our civilization calls for the efforts of every member living in this large community.
