But do you know “low­carbon community(低碳社区)”？What is the community like? What benefits(好处) will it bring to our environment? Let's have a look at Hanbei Road Community of Ya'an, Sichuan Province. Walking into the community, people can see the hanging environmental slogans(环保标语) at first sight. And the most eye­catching items are idle bins(闲置物品投放箱) around. Many people in the community would give their idle things into the bins. Xu Juan, a mother of two, once put a pair of gloves there. “I think it's meaningful to help others.” In order to encourage more people to join in the “low­carbon” activity, the community introduced a reward program. Anyone can get some points if he/she gives idle things or takes part in volunteer activities. With certain points, people can exchange things in the “low­carbon supermarket” in the community. There is also an “exchange corner” in the community. People can exchange their idle things(except the living things) with others. If he/she is not interested in any idle things in the corner, he/she can donate(捐赠) his/her things to poor families in the community. “We are trying to make the best use of idle things by free exchange and donation. We hope all the people in our community can live a low­carbon life，” said Wang Lu, leader of Hanbei Road Community. 1.
