The main cause of a heart attack is not exercise or stress - it's air pollution, according to a study
published inThe Lancetthis month. Researchers found spending time in traffic, whether as a driver or a
pedestrian(行人), tops the list of risk factors that bring on a heart attack.
Jon Ayres, professor of environmental and respiratory(呼吸的) medicine at the University of
Birmingham, says, "Air pollution is not only linked to strokes, heart attacks and cancer - it has a deep
effect on those with existing respiratory conditions." So how can you avoid the damage? We asked the
experts for their tips.
TAKE TO THE SIDE STREETS
Avoid main roads. These have the highest number of vehicles and also more traffic jams, which tend to run ondiesel(柴油). Diesel enginesemit(排放) tinyparticles(粒子) that reach the lungs most easily.
Choose side streets, pavements, parks and avenues lined with trees.
BUY SOME HOUSEPLANTS
We spend 90 percent of our time inside, but studies by the U.S. Environmental Protection Agency have found that pollution levels can be two to five times higher indoors than outside. Objects such assynthetic(合成的) carpets, TV screens can emit chemicals called volatile organic compounds (VOC,挥发性有机化合物), which have been linked to diseases such as cancer. Researchers at Curtin University in Perth,
Australia, found an increase inasthma(哮喘) risk among children under three who had high VOC levels
in their homes. Therefore, the application of air fresheners and houseplants can keep the circulation of the
air and absorb the pollutants.

       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。
【阅读策略】
1、概要(Summarizing)：
      阅完材料后，将所阅材料浓缩，摘要，做出所阅材料的书面或口头梗概。
