问题                                                 环保节能
     人们普遍认为空气污染与汽车、飞机、发电厂以及其他涉及燃烧汽油和天然气的人类活动有关。在过去的150年里，这些人类活动向大气中排放的二氧化碳比过去几十万年排放的二氧化碳还要多。人们正在学习合理选择交通工具。如果可以的话，应当走路，骑自行车，或者乘坐公共交通工具。如果要开车，就选择每加仑汽油跑得更远的汽车或者电动汽车。科学家们正在研究能减少环境破坏的新发电方式。
选项
答案     Air pollution is widely considered to be associated with cars, planes, power plants, and other human activities that involve the burning of gasoline and natural gas. In the past 150 years, such activities have pumped enough carbon dioxide into the atmosphere to raise its levels higher than they have been for hundreds of thousands of years. People are learning to make good choices about transportation. If you can, walk, ride a bike, or take public transportation. For driving, choose cars that get better miles per gallon of gas or choose an electric car. Scientists are studying new ways of generating electricity that can reduce damage to the environment.
