第二节 读写任务（共1小题，满分25分）
阅读下面的短文，然后按照要求写一篇150词左右的英语短文。
The U.N. Climate Change conference opened in Copenhagen, Denmark on Dec.7th with some 15,000 delegates and observers from nearly 200 countries attending what is called the last best chance for an agreement to combat global warming.
Most scientists believe the warming trend is mainly caused by human activity, especially the use of fossil fuels (化石燃料) and the cutting down of forests. In Copenhagen, experts and officials alike are putting the emphasis on what people and governments can do to cut the emission (排放) of greenhouse gasses. Scientists say a 25 to 40 percent cut in carbon-dioxide emissions is needed to control global warming.
A youthful online group that calls itself the "Low-Carbon Tribe" is leading the way to an eco-friendly lifestyle. Tribe members, who range in age from 20 to 40, say they are trying to reduce carbon dioxide emissions in a relaxed and fashionable way. Helping save the planet is part of their daily routine, they claim, citing the way they dress, what they eat and how they travel.
