China has decided to take action to stop the use of free plastic bags at shops and supermarkets, and people have to pay for using plastic bags. The rule (规定) started on June 1. It came because our country tried to make litter less. The Chinese once used about 3,000,000,000 plastic shopping bags a day, and they made the environment pollution more serious and wasted a lot of energy as well. People throw the used plastic bags away here and there. The thrown-away plastic bags are not easy to break .So the Chinese government encourages people to bring their own bags or baskets for shopping. What kind of shopping bag is the best to bring? Some students have good ideas. They make their own shopping bags. They use old clothes to make cloth bags (布袋), and send them to their parents as presents. They also ask their parents and friends to use cloth bags instead of plastic ones. They think it is their duty to protect the environment. | ||||||||
