Scientists measured the impact that people have on the enviroment using a term called carbon "footprint". That footprint reflects the amount of carbon dioxide that is emitted (排放) into the atmosphere as a result of someone’ s daily activities. Carbon footprints tend to be low for city dwellers (城镇居民). Living in a suburb outside a city, however, can turn that footprint into a bootprint.
Energy researchers Christopher Jones and Daniel Kammen calculated carbon footprints for people in every zip code across the United States. People living in city centers had small footprints , the researchers found. " It is much easier to have a low carbon impact if your home is close to where your work, shop and play, " explains Jones. Living within walking or biking distance cuts back on the amount of carbon dioxide associated with moving people by cars. And cities with extensive bus and subway networks allow people to travel great distances while keeping releases of climate-altering greenhouse gases low.
Not everyone can afford to live in the city, however. And not everyone wants to. Rings of suburbs have popped up around major cities across the world. Suburbs offer more space, allowing people to build larger homes. Suburbs may offer better schools for a family’ s kids. But those homes are typically well beyond walking distance from where their owners work, play and learn. So people who live in suburbs often drive long distances.
The new findings are an important contribution to climate research, says Matthew Kahn, an enviromental economist at the University of California, who was not involved with the study. Kahn would like to see the analysis applied to other parts of the world—Europe, India and China, for instance. That would give scientists a better feel for how culture might mix with location to influence our carbon footprints.
What is the purpose of the author in writing the passage?
选项
A、To call on people to reduce carbon footprints.
B、To offer tips on how to live a low-carbon life.
C、To clear up misunderstandings about carbon emission.
D、To introduce the research on carbon footprints.
答案
D
解析
主旨题。文章第一段讲城镇居民和郊区碳足迹的差别。第二段讲能源研究人员发现城市居民由于距离工作、购物和玩耍的地方较近,因此比住在郊区的居民碳足迹低。第三段讲住在郊区除了在碳排放量方面外其他方面的好处。第四段讲环境经济学家卡恩对这项研究的肯定。因此文章的中心是对碳足迹的研究。选项A(号召人们减少碳足迹)、选项B(给出低碳生活的建议)和选项C(消除对碳排放的误解)均不是文章主旨,故本题选D。
