      Most supermarkets in China provided free plastic bags. It was convenient for people to do shopping, but things changed. To protect the environment, supermarkets all over China stopped providing free plastic bags from June 1st, 2008. If you don't want to pay money to buy them, you'll have to bring your own

shopping bags.

      What can we use to hold things we buy from shops? Students at Qingshan Middle School had some

good ideas. One idea was making different kinds of eco - shopping bags. 54 students at that school made

their own eco-shopping bags. They held an eco - shopping bag show last Friday afternoon. Many students made the bags with used clothes. They painted pictures like the Olympic rings on them. Some bags were

made of used materials like used paper, old newspapers. Some were made of eco - materials like

bamboo. 

      A boy student, Wang Lin made his bag with several old newspapers. We asked him whether the bag was strong enough. Wang Lin said it was. "No problem. I took six bottles of water in the bag from the

shop to my home yesterday evening," he said. "I think it's strong enough to hold even ten bottles of water. "

      Fang Yuanyuan, a girl student, had a more traditional way to make her bag-a bamboo basket.  "It was a hard job," she said. "With my grandfather's help, I spent a whole afternoon making it. "

      The students also asked their parents and friends to use eco - shopping bags instead of plastic ones.

Next Saturday afternoon, the school will hold another eco - shopping bag show to help shops and stores

get ideas from the students' work
