What will the future be like?
Recently our class has held a discussion on “What will the future be like?”.Some students think that in the future science will be more advanced, and transportation will be more convenient.What’s more, people will live much longer and the level of their living conditions will be higher.However, some students think that in the future natural resources will further decrease and farmland will become lost(will decline sharply).There will be more traffic accidents.In my opinion, we should try to protect natural resources and decrease environment pollution.I hope everyone can be aware of the importance of environment protection and make our efforts for the better world in the future.

Pollution Harms Us
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.I suggest that effective measures should be taken to stop the pollution.
