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.
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

[单项选择]Two travelers engaged in a warm dispute about the color of the Chameleon. One of them affirmed it was blue, that he had seen it with his own eyes upon the naked branch of a tree, feeding on the air in a very clear day. The other strongly asserted it was green, and that he had viewed it very closely and minutely upon the broad leaf of a fig tree. Both of them were positive, and the dispute was rising to a quarrel; but a third person luckily coming by, they agreed to refer the question to his decision. "Gentlemen," said the Arbitrator, "You could not have been more lucky in your reference, as I happen to have caught one of them last night; but, indeed, you are both mistaken, for the creature is totally black." "Black, impossible." "Nay," said the Umpire, with great assurance, "the matter may be soon decided, for I immediately enclosed my Chameleon in a little box, and here it is." So saying, he drew it out of his pocket, opened the box, and, lo! It was white as snow.
