Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.
The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK. w.w.w.k.s.5.u.c.o.m
“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
“This gender difference might just explain why women live longer than men,” said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. “The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

Very old people do raise moral problems for almost everyone who comes in contact with them. Their values—this can’t be repeated too often—are not necessarily our values. Physical comfort, cleanness and order are not necessarily the most important things. The social services from time to time find themselves faced with a flat with decaying food covered by small worms, and an old person lying alone in bed, taking no notice of the worms. But is it interfering(干涉) with personal freedom to insist that they go to live with some of their relatives so that they might be taken better care of? Some social workers, the ones who clear up the worms, think we are in danger of carrying this concept of personal freedom to the point where serious risks are being taken with the health and safety of the old.
Indeed, the old can be easily hurt or harmed. The body is like a car, it needs more mechanical maintenance(機械維修，保養) as it gets older. You can carry this comparison right through to the provision of spare parts. But never forget that such operations are painful experiences, however good the results will be. And at what point should you stop to treat the old body? Is it morally right to try to push off death by seeking the development of drugs to excite the forgetful old mind and to activate the old body, knowing that it is designed to die? You can’t ask doctors or scientists to decide, because so long as they can see the technical opportunities, they will feel bound to give them a try, on the principle that while there’s life, there’s hope. w.w.w.k.s.5.u.c.o.m
When you talk to the old people, however, you are forced to the conclusion that whether age is happy or unpleasant depends less on money or on health than it does on your ability to have fun.

A. The values are different between the old and the young. B. The moral problems raised by old people.
C. The personal freedom for the old. D. Old people’s viewpoint on life.
2. We can know from the first paragraph that________.
A. Very old people would like to live alone to have more personal freedom.
B. Very old people are able to keep their room clean.
C. Very old people like to live with their children.
D. Social services have nothing to do with very old people.
3. According to the author, which of the following is right?
A. The older a person, the more care he needs. B. Too much emphasis has been put on old people’s values.
C. The human body can’t be compared to a car. D. It is easy to provide spare parts for old people.
4.The underlined word “it” in the last paragraph refers to “________”.
A. their money or their health B. the conclusion you come to
C. your talk to the old people D. whether age is happy or unpleasant

NEW YORK—America has been experiencing the longest economic increase in its history．Incomes have risen, unemployment has fallen, and cities such as New York are bursting with new office buildings．

Brown, the homeless New Yorker, said he has a daughter who lives in the city but he rarely sees her．She is angry about his drinking and won't allow it in her house．
Smiling, he said he also has seven grandchildren whom he'd like to see more often．
