One day,Lihua went shopping at supermarket. When he wanted to pay for his goods at the checkout, and he needed a bag for what he have bought, he be told to pay for it, but he thought that as too much use of plastic bags has caused serious white pollution, our govenment encourages us to use environment-friendly shopping bags. These bags are made of a variety of material that can be easily treated when they become rubbish.Besides, they can be reused. More and more people in China have realized the advantages of such bags and started using them. So in order to protect the environment, Lihua decided to go home, and made a bag by his old trousers. Certainly, his action has been appreciated by mom.
