题文
阅读理解 The main cause of a heart attack is not exercise or stress - it's air pollution, according to a studypublished in The Lancet this 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 on diesel(柴油). Diesel engines emit(排放) tiny particles(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 as synthetic(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 in asthma (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.1. According to the first paragraph, what causes a heart attack mainly?A. Exercise
