Obviously, air pollution is the main factor that has resulted in the frequency of hazy weather.At the same time,smoke from burning coal and all kinds of dust are also important factors.Besides,exhaust emission from cars and buses has made the situation even worse. So proper measures should be adopted to deal with the serious problem.To students,opportunities for outdoor sports activities should be decreased, washing faces and hands with running water after each outing is also important, and do not forget to wear a good-quality mask to protect yourself while going out. I ( tianmaoUSApuweixin) hope we will regain a fresh,clean and bright world soon.
