Our school lies at the foot of a mountain with a river passing by. There used to be many green trees and all kinds of flowers in our school all the year round. It looked like a beautiful garden and was a nice place for us to study in, but everything has changed since a chemical works was built near our school a year ago. Every day it produces a lot of waste water and harmful gases. The terrible pollution has done great harm to our health and the great noise from the factory has greatly affected our teaching and studying activities.
