题文
Scientists studying the impact of climate change on the Arctic need to consider ways to reduce theirown carbon footprints(碳排放量), says Ryan Brook, a researcher who regularly flies north to study the
health of caribous (驯鹿). He calls on scientists to show leadership by examining and sharing ways to
reduce the impact of working in polar regions.
"The importance of the research is not at question here. It is important to our understanding of and
adapting to climate change. But we need to think about better approaches." says Brook.
"This is an issue for all scientists, though polar researchers often travel particularly long distances
using commercial air travel. We also rely extensively on small aircraft, icebreakers, and snowmobiles, all
of which produce large amounts of carbon. "
Brook studies the health of caribous herds in Nunavut and Northwest Territories. He works with
northern wildlife managers. This work typically takes him north five or six times per year and when he
calculated his own carbon footprint, he was not happy with the result.
"My research footprints are about the same as the annual footprints of an average Toronto resident.
Basically, I have two footprints-my own personal life, which is moderate, and my research footprint."
Climate scientists can rightly argue that Arctic research is a specialized field and the community of
scientists who travel north is relatively small. Even if all scientists working in the north reduced their
carbon emissions, it would not make a big impact on the global scale. For Brook, it's the option that
matters.
There are ways researchers can reduce the amount of carbon they use. Some helicopters use less
fuel than others. Solar and wind power are alternatives to gasfired generators. And while carbon offsets
(抵消) don't reduce the amount of carbon emitted, they ar
e an easy first step.
"There aren't necessarily any easy answers, but we need to start talking about it." says Brook. "This is
particularly important for the next generation of scientists being trained and I hope to see them become
leaders in this issue."1. The underlined word"It" in Para. 2 refers to________. A. the research of climate change on the Arctic
B. the study of the health of caribous
C. the impact of working in polar regions
D. the reduction of polar scientists' carbon emissions2. What did Brook find when he calculated his own carbon footprints?A. His carbon footprints are more than the annual footprints of a Toronto resident.
B. His personal life footprints are more than the annual footprints of a Toronto resident.
C. His research footprints are about the same as his personal life footprints.
D. His personal life footprints are more than his research footprints. 3. Brook's opinion is challenged by the statement that____. A. arctic research is very important
B. the Arctic is a special environment
C. the footprints of Arctic scientists are small
D. Brook's situation is not a common phenomenon4. We can infer from the last paragraph that________. A. we should take actions immediately instead of just talking
B. it's easy to start talking about the problem of carbon emissions
C. it's necessary now to pay attention to the problem of research footprints
D. the next generation of scientists are more interested in research footprints 题型：未知难度：其他题型

考点
据考高分专家说，试题“ Scientists study.....”主要考查你对 [健康环保类阅读 ]考点的理解。健康环保类阅读
健康环保累阅读概念：
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。体裁有记叙文、 说明文、议论文和各种应用文。
健康环保类文章阅读技巧：
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考，理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文，从结构上看大致可分为三个部分：
第一部分一般是文章的首段，主要用来提出文章的主题，即文章想要阐述、说明的主要内容；
第二部分是文章的主体，可由若干个段落组成，对文章的主题进行展开说明；
第三部分是结尾段，对文章的主题进行归纳总结。这类文章多用一般现在时，而且一般多使用客观性词语表述。有时为了强调客观性，也常使用被动语态。
从近几年的考试题来看，科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节，很多同学对此类文章感到费解。但一般的科普类文章都是就事论事，需要逻辑推理和想象的时候较少，因此此类阅读题也没有同学们想象中的那么难，只要多加训练，就能较好地答题。
