Breathing dirty air can cost someone's life span (寿命) months—even years, a new study finds. Worldwide, air pollution lowers average life spans by a year. Scientists shared their new findings in Environmental Science & Technology Letters.
Air pollution has been linked to many health problems. Most earlier studies have looked at how tiny air pollutants affected rates of illness or death. But now an environmental scientist, Joshua Apte, is going even further. He works at the University of Texas, Austin. He together with his team is looking at life expectancy, hoping to make the threat easier to understand.
PM 2.5 is what scientists call tiny particles of pollution in the air. Higher levels of PM 2.5 can cause health problems and cut months, if not years, from the average life span. This analysis shows how pollution affects life expectancy in different parts of the world.
The World Health Organization (WHO) recommends limiting PM 2.5 to 10 micrograms (微克) per cubic (立方) meter of air. Apte's group used data to try to find how this low level would help people. But meeting the WHO standard won't get rid of health damage from dirty air. That's because even below 10 micrograms per cubic meter pollution still causes huge risks.
Reducing air pollution could increase life expectancy. The scientists also compared how other threats shorten life spans across the globe. These risk factors included smoking and cancer.
These results show that in poor countries, cleaning up dirty air could greatly increase life spans. It could have as big an effect as cleaning up drinking water, or curing lung cancer. However, in wealthier countries air pollution shortens life expectancy by less than half a year. All forms of cancer, in fact, shorten the average life expectancy by more than 3.5 years.“Knowing this can really help people, or policymakers, decide where to spend their money,” says Kirk Smith.
篇章导读:本文是一篇说明文。文章阐述了空气污染会缩短人类寿命的科学理论。
4.What is Joshua Apte's team trying to do?
A.Let people understand air pollution better.
B.Know how small air pollutants are.
C.Study the life expectancy of different people.
D.Study many different healthy problems.
答案:A 细节理解题。根据第二段最后一句“He together with his team is looking at life expectancy, hoping to make the threat easier to understand.”可知,Joshua Apte(乔舒亚·阿普特)的团队希望让人们更容易地理解空气污染给他们带来的威胁。故选A。
5.What will happen if one country limits PM 2.5 to 10 micrograms per cube meters?
A.Its people will live a healthy life.
B.Its air is very clean.
C.It will get a prize from WHO.
D.It still has pollution risks.
答案:D 细节理解题。根据第四段第一句“The World Health Organization (WHO) recommends limiting PM 2.5 to 10 micrograms (微克) per cubic (立方) meter of air.”可知,WHO建议将空气中的 PM 2.5含量限制在每立方米10微克。再根据最后两句“But meeting the WHO standard ... still causes huge risks.”可知,即使满足了这一标准,也仍然存在着污染的风险。故选D。
6.What can we infer from the last paragraph?
A.Cancer is the leading killer in all kinds of diseases.
B.It's very hard to clean up dirty air in a short time.
C.The study will help different countries take different policies.
D.Reducing air pollution can increase all people's lifespans much.
答案:C 推理判断题。根据最后一句中的“Knowing this can really help people, or policymakers, decide where to spend their money”可知,这个研究成果可以帮助不同国家根据国情制定不同的政策。故选C。
7.What can be the best title for the text?
A.The Effect of Cancer Is Worse than Dirty Air
B.Air Pollution Is Shortening Lives Worldwide
C.Many Factors Are Affecting People's Health
D.Governments Are Trying to Make Life Span Long
答案:B 标题判断题。文章主要阐述的是在全世界范围内,空气污染会缩短人类寿命的科学理论。故选B。
