     Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is
another factor that can cause your heart problems more immediately: the air you breathe.
     Previous studies have linked high exposure (暴露)to environmental pollution to an increased risk of heart problem,
but two analyses now show that poor air quality can lead to heart attack or stroke (中风)within as little as a few hours
after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物)were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate
study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of "moderate" (良好)quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14
hours of exposure.
     The authors of both studies stress that these risks are relatively small for healthy people and certainly modest
compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware
of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation
by the EPA of pollutants may not only improve environmental air quality but could also become necessary to
protect public health.

1. The text mainly discusses the relationship between       .

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。
【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。
2、组织(Organization)：
      阅读后根据阅读内容，识别观点、人物、事件之间的关系以及文章的结构关系。如：时间关系、比较或对比关系、相关关系及因果关系等。
