阅读理解。 A new study has revealed that non-smokers who repeatedly breathe in others' tobacco smoke are more
likely to have some degree of hearing loss. Researchers studied a total of 3307 adults aged between 20 and
69. The degree of hearing loss in each ear was assessed by testing the ability to hear pure tones over a range
of frequencies from 500 Hz (low) to 8000 Hz (high).
Men, those who were older, and those with diabetes (糖尿病) were significantly more likely to have high
frequency hearing loss. And this was true of those who were former smokers and those who had never
smoked. But even after taking account of these factors, both former and passive smoking were associated
with damaged hearing.
Former smokers were significantly more likely to have damaged hearing. The prevalence (流行程度) of
low to mid frequency hearing loss among this group was 14 percent. And almost half (over 46 percent) had
high frequency hearing loss. Although the risk was not as strong among those who had never smoked,
almost one in 10 (8.6 percent) had low to mid frequency hearing loss and one in four (26.6 percent) had high
frequency hearing loss.
And the stronger findings among former smokers suggested that continued passive smoking in this group,
even at low levels, could continue the progression of high frequency hearing loss that began when they were
active smokers, say the authors.
"Further research is required to determine whether passive smoking increases the effect of noise exposure
and aging on hearing," they conclude."If this finding is independently /confirm/ied, then hearing loss can b
e added to the growing list of health consequences associated with exposure to second-hand tobacco smoke."

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。
