| We students often talk about the rules that we have in school , such as "Don't fight.""Clean the classroom every day."…We should obey these rules . The problem is that we have to wear uniforms at school every day,but all my classmates think the uniforms are ugly. We think that young puopke should look smart and so we would like to wear our own clothes .Our teachers believe that if we do that ,we woule concentrate more on our clothes than our studies .We disagree. We should feel more comfortable and that is good for studying .If we can't do that ,we should be allowed to design our uniforms. That would be a good way to keep both teachers and students happy. | |||
