Napping to a Healthier Heart?

1 Researchers say they have developed a simple test that can tell if a person with heart disease is
likely to suffer a heart attack.The test measures levels of a protein in the blood.The researchers say people
with high levels of this protein are at high risk of heart attack,heart failure or stroke.
2 Kirsten Bibbins-Domingo of the University of California in San Francisco led the team.For about
four years,they studied almost one thousand patients with heart disease.The researchers tested the heart
disease patients for a protein called NT-proBNP. Patients with the highest levels were nearly eight times more
likely than those with the lowest levels to have a heart attack,heart failure or stroke.
3 The researchers say the presence of high levels of the protein in the blood shows that the heart
muscle is under pressure in some way.The study involved mostly men,so the researchers could not say for
sure that the results are also true for women.They say the patients with the highest levels of NT-proBNP
were older and had other problems like diabetes or high blood pressure.
4 Other researchers say more studies are needed to confirm if knowing the protein levels of a heart
disease patient should affect that person’s treatment.They also would like to know if more aggressive
treatment could reduce the patient's chance of a heart attack or stroke.The study appeared in the
Journal of the American Medical Association.
5 Could a little sleep during the middle of the day reduce the risk of a heart attack?An unrelated
study earlier this month in the Archives of Internal Medicine suggests that the answer may be yes.In countries
like the United States,afternoon naps are mostly for children. But they are common for adults in
Mediterranean countries.And these countries generally have lower rates of heart disease.So scientists in the
United States and Greece wondered if naps could play a part.Twenty-three thousand healthy adults took part
in the study by Harvard University and the University of Athens.Those who took thirty-minute naps three
times a week had a thirty-seven percent lower risk of death from heart problems than people who did not take
naps.
6 The researchers say napping may improve heart health by reducing stress.They say the research
suggests that naps are especially good for working men.But they say not enough female subjects died during
the study to judge the benefits for women.
选项 Paragraph 4 _________
A:More Questions to Be Asked
B:Older Males Have Higher Levels of NT-proBNP
C:Development of a Simple But Important Test
D:Evidence of Positive Relationship Between Napping and Heart Discase
E: How to Control the Levels of NT- proBNP
F: Effects of NT-proBNP on Heart Disease
答案A
解析由第二段后面两句可知，通过检查心脏病人的NT-proBNP水平，发现水平最高的病人 与水平最低的病人之间患心脏病的可能性相差近8倍。
第三段说到，研究涉及的多是男性，并发现老年男性且患有糖尿病和高血压者 NT-proBNP的水平最高。
由第四段的内容可知，其他研究者认为还要确认一些问题，如心脏病病人蛋白质水平 是否影响其治疗；他们还想知道更多的积极治疗能否减少病人得心脏病和中风的机会。
第五段说到，地中海国家的成年人普遍都午睡，而且患心脏病的几率较低。哈佛大学 和雅典大学的研究证明，每周午睡三次，每次30分钟的人比完全不午睡的人死于心脏病的几 率低37％。
答案来源于第一段的第二、三句。
答案来源于第三段第一句。
答案来源于第五段第一、二句和该段最后一句。
答案来源于第三段第二句和文章的最后一句。第4部分：阅读理解第一篇 本篇文章主要讲述了普通感冒的传播特点及其预防和治疗。
