课文译文
中国人爱上低碳生活
众所周知，低碳生活就是降低二氧化碳的排放量，其特点就是低能量，低消耗、低开支。由于气候恶化带来的威胁越来越明显，人们正在重新思考生活方式，我们有责任把我们的地球建设为一个低碳的星球。降低碳排放量，选择低碳生活，已经成为每一个公民的职责。
当前，很多中国人已经开始接受低碳的生活。人们对这种生活方式也越来越感兴趣了，喜欢把他们的低碳日记或低碳小贴士放到网络上，号召更多的人参与到低碳活动中，如双面使用张纸，离开房间时关闭电源，步行、骑自行车或乘地铁上班，使用电子邮件或MSN，减少使用打印机、传真机等。
上海有一个绿色宾馆，其建筑材料全部来自废弃的建筑物。在接待处，电脑可以测量每一位旅客在途中的碳释放量，然后计算出吸收这些碳需要多少棵树。旅客向宾馆支付一定的费用，宾馆就可以帮旅客在华北地区的内蒙古种植这些树木。
中国现在正在重新思考她的发展模式，我们有责任把中国建设成为一个低碳环保的国家。
