In order to build a civilized city, we students are supposed to behave well in our daily life. First, we should choose to live a low carbon life. We'd better go to school by bike or on foot. When we are shopping, we can use baskets or cloth bags instead of plastic bags. We should also pay attention to saving. We must say NO to waste. We shouldn't buy anything we don't need.
Second, it's our duty to protect the environment. We mustn't throw rubbish about and we should take care of trees and flowers.
Third, it's necessary for us to show good manners to others/be polite to others. We need to say polite words such as “Thank You. I'm sorry and Please” as often as possible.
Finally, we should devote ourselves to helping others. We should learn from Lei Feng and be willing to help others. It's important for us to take part in voluntary work.
We should try our best to make our city more and more beautiful!
