Last month, I participated in an activity called Green School Month. This is a beautiful month. There was a speech on the playground every morning last month. The speech talked about that people should be green to protect our environment. I made some special boxes in the classroom. They are made of old newspapers. I named them Li Ke, because in the process of creating them, I realized that everyone can do something for our environment. I hope my school will become greener and more beautiful.
