参考答案：

　　The carbon discharge of a three-member Chinese family, on an average，was 2.7 tons in

　　2006. Now, this feature has jumped to 3.5 tons. In such large cities as Beijing, Shanghai and

　　Guangzhou, the average household carbon emissions have approached 10 tons. Carbon sink

　　refers to the capacity of forests to absorb and store carbon dioxide. Forests, as the largest

　　carbon sinks in the continental ecological system, play a very important and unique role in

　　lowering the concentration of greenhouse gas in the atmosphere and slowing down global

　　climate warming.

　　According to statistics, each person only needs to plant three trees a year to absorb his

　　carbon dioxide emissions during the same period. China is developing carbon sink forest

　　projects for public participation, such as the giant panda carbon sink forest project to be

　　built in the giant panda habitat in Sichuan Province. Some large carbon dioxide discharging

　　companies have taken actions by building more than 600,000 hectares of carbon sink forests

　　in over a dozen provinces and autonomous regions throughout the country. China will

　　promote actions like purchasing carbon sinks and planting carbon sink trees to speed up

　　afforestation and increase forests' capacity as carbon sinks.
