Go green at school 
Hi, guys,
      Isn't it pleasant to study in an environmentally friendly school? To develop a green lifestyle, we students can go green at school in smaller ways.
      On one hand, we should save resources. First, we should save paper. We can reuse the textbooks and use both sides of the paper. Second, we should save water. We can take short showers and reuse water. Third, we are supposed to save electricity. We can turn off the light when we leave from the classroom. Also, we needn't turn on all the lights if enough.
       On the other hand, we should reduce pollution. We can protect the trees and flowers, choose the public transport and use the cloth bags instead of plastic bags. We should develop a green lifestyle, we can do more exercise and watch less TV. If we take good care of our earth today, it will be more beautiful tomorrow.
       That's all. Thank you!
