【录音原文】
Despite these billions, the rate of death from cancer in the United States has increased from 163 per 100,000 individuals in 1971 to 194 per 100,000 in 2001. By contrast, mortality rates from heart disease and strokes, two other diseases often seen as being associated with affluent styles of living, have fallen.

U.S.Eats Too Much SaltPeople in the United States consume more than twice the recommended amount of salt,raising their risk for high blood pressure,heart attacks and strokes,government health experts said on Thursday.They found nearly 70 percent of U.S.adults are in high-risk groups that would benefit from a lower-salt diet of no more than 1,500 mg per day,yet most consume close to 3,500 mg per day.“It's important for people to eat less salt.People who adopt a heart-healthy eating pattern that includes a diet low in sodium and rich in potassium and calcium can improve their blood pressure,”Dr.Darwin Labarthe of the Centers for Disease Control and Prevention said in a statement."People need to know their recommended daily sodium limit and take action to reduce sodium intake,"Labarthe said.The study in CDC's weekly report on death and disease used national survey data to show that two out of three adults should be consuming no more than 1,500 mg of sodium per day because they are black or over the age of 40-which are considered highrisk groups.Yet studies show most people in the United States eat 3,436 mg of sodium per day,according to a 2005-2006 CDC estimate.Most of the sodium eaten comes from packaged,processed and restaurant foods.The CDC said it will join other agencies in the Health and Human Services department in working with major food manufacturers and chain restaurants to reduce sodium levels in the food supply.Nationwide,16 million men and women have heart disease and 5.8 million are estimated to have had a stroke.Cutting salt consumption can reduce these risks,the CDC said.Packaged,processed and restaurant foods are known to be______.A:cheapB:tastyC:rich in saltD:healthy

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 heartdisease 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 theJournal of the American Medical Association.5 Could a little sleep during the middle of the day reduce the risk of a heart attack?An unrelatedstudy 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 theUnited 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 takenaps.6 The researchers say napping may improve heart health by reducing stress.They say the researchsuggests 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.If a person has a high level of NT-proBNP_________.A: where fewer pepole die from heart problemB:whether they have the risk of heart attack,heart failure or stroke C:would probably have lower rates of heart diseaseD:how to test a person's NT-proBNP level in the blood by himselfE:his heart muscle would be under pressure in some wayF:that napping is of great benefit to women too
