Question

If you want to live longer and lower the risk of heart disease, a move to the mountains may help. Research by scientists in Greece shows that living in the mountains is good for the heart and longevity(长寿). People living at higher altitude(海拔) have lower possibility of dying from heart disease than those closer to sea level, even if they have factors that could increase their risk. "Residence in mountainous areas seems to have a ‘protective effect’ from heart disease," said Dr Nikos Baibas of the University of Athens. He and his colleagues suspect that the increased exercise from walking up mountainous area gives the heart a good workout and enables it to cope with lower levels of oxygen.

Researchers studied the health records and death rates of 1,150 Greeks who lived in three villages near Athens over 15 years. One village was 1,000 meters above sea level and the other two were in low-lying areas. Although men and women living in the mountainous village had higher blood pressure rates and other risk factors than people in the other villages, they had a lower rate of death from heart disease and other causes after a fifteen year follow-up." The contrast was more evident among men than among women," Baibas added in a report in the Journal of Epidemiology and Community Health. Heart disease is one of the world's top killers. Smoking, high blood pressure, raised cholesterol levels, being overweight and a family history of the illness increase the possibility of developing the disease.

【解析】

试题分析：本文讲述了多年研究表明，居住在高海拔处的人们死于心脏病的几率比低海拔处的人们低。但吸烟、高血压、高的胆固醇水平、过重和家庭疾病历史共5点也会增加心脏病的机率。

1. 推理判断题。文章第一句告诉我们“如果想长寿并降低心脏病的风险，可以搬去山里住”，下面都是围绕这句话的内容，所以这一句让读者明白了全文谈论的主题，故选B。

2. 细节理解题。根据第一段People living at higher altitude(海拔) have lower possibility of dying from heart disease than those closer to sea level, even if they have factors that could increase their risk.可知，居住在高海拔处的人们死于心脏病的几率比低海拔处的人们低，故选A。

3. 细节理解题。根据第二段首句Researchers studied the health records and death rates of 1,150 Greeks who lived in three villages near Athens over 15 years.可知，这项研究持续了15年多，故选D。

4. 细节理解题。根据最后一段Smoking, high blood pressure, raised cholesterol levels, being overweight and a family history of the illness increase the possibility of developing the disease.可知，除海拔外，还有吸烟、高血压、高的胆固醇水平、过重和家庭疾病历史共5点也会增加心脏病的机率，故选C。

考点：考查健康类短文阅读。

【名师点睛】

在做阅读理解题过程中，应首先略读一下短文，了解一下短文的大致意思，然后把几个选项含义理解透，尤其注意意思相近，表达有交叉的选项之间的区别。然后再细读短文，把答案填入合适位置。答题时可以把含义相近的几个选项轮流填入同一处位置，反复阅读，反复体会，找出最佳选项，对于实在没有把握的小题可以最后完成。完成短文后，再认真通读一遍全文，看看上下语意是否通顺，是否符合逻辑关系。要看完全文，关键对方反复阅读，才能选对答案。

另外，做题时要注意文章的首段和每一段的首句或尾句，因为它们往往就是文章的主题句。阅读中要注意要点之间的关系。
