问题补充：
Id like to tell you something about the problem of pollution we are facing to. As we know, the factory beside our school gave off heavy smoke all day long. Very loudly noises hurt our ears. Rubbish and waste are thrown here or there. It also sends out polluting water and poisonous gas. All this has done great harms to the health and study of the teachers and students. But as time goes on, a little has done to change the situation. I don think you can study well after the problem is solved. We do hope youll help and support us.去掉to
