As people continue to grow and age, our body systems continue to change. At a certain point in your life your body systems will begin to weaken. Your joints may become stiff. It may become more difficult for you to see and hear. The slow change of ageing causes our bodies to lose some of their ability to bounce back form disease and injury. In order to live longer, we have always tried to slow or stop this process that leads us toward the end of our lives.Many factors contribute to your health. A well-balanced diet plays an important role. The amount and type of exercise you get is another factor. Your living environment and the amount of stress you are under is yet another. But scientists studying senescence (衰老)want to know: Why do people grow old They hope that by examining the ageing process on a cellular level medical science may be able to extend the length of life.There is nothing to be afraid of as old age approaches. Many consider the later portions of life to be the best time for living. Physical activity may lessen, but often you gain a broader understanding of yourself and the world.What we consider old age now may only be middle-aged some day soon. Who knows, with so many advances in medical science happening so quickly, life spans may one day be measured in centuries, rather than in years! The main idea of this passage is how to live longer.()

A. Right
B. Wrong
C. Not mentioned

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 sure5 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 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. So far there have not been definite data to confirm ______

Men Too May Suffer from Domestic Violence Nearly three in 10 men have experienced violence at the hands of an intimate partner during their lifetimes, according to one of the few studies to look (51) domestic violence and health among men.

Reid of the University of Washington in Seattle, one of the study’s authors, told Reuters Health. "They often don’t tell (53) we don’t ask.

C. Overall, 30. 5 percent of men younger than 55 and 26.5 percent of older men said they had been victims of (60) violence at some point in their lives. About half of the violence the men (61) was physical.
D. However, the physical violence men reported wasn’t as harsh as (62) suffered by women in a previous study; 20 percent to 40 percent of the men rated it as severe, compared to 61 percent of (63) .
