I felt that we can do our work silently when we are told to do so. Even if we are not told to do so, we must think of others. Others may could not think of things to answer the question if it is too noisy. Therefore, we must think for others in order to get respect from others. I felt that doing homework in lesson will be better as everyone will hand in work on time and there will not be any misunderstanding like copying others people work. Everything we do must have intergrity. Even if we are told to do our homework at home, we must no copy other people hard work as there is a chinese saying, there is no free lunch in this world(天下没有免费的午餐。）
