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 hardly 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. “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 (性别)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.

While watching the Olympics the other night, I came across an unbelievable sight. It was not a gold medal, or a world record broken, but a show of courage.
The event was swimming and started with only three men on the blocks. For one reason or another, two of them false started, so they were disqualified. That left only one to compete. It would have been difficult enough, not having anyone to race against, even though the time on the clock is important.
I watched the man dive off the block and knew right away that something was wrong. I’m not an expert swimmer, but I can tell a good dive from a poor one, and this was not exactly medal quality. When he resurfaced, it was evident that the man was not out for gold – his arms were waving in an attempt at freestyle. The crowd started to laugh. Clearly this man was not a medal competitor.
I listened to the crowd begin to laugh at this poor man who was clearly having a hard time. Finally he made his turn to start back. It was pitiful. He made a few desperate strokes and you could tell he was worn out.
But in those few awful strokes, the crowd had changed.
No longer were they laughing, but beginning to cheer. Some even began to stand and shout “Come on, you can do it!” and he did.
A clear minute past the average swimmer, this young man finally finished his race. The crowd went wild. You would have thought that he had won the gold, and he should have. Even though he recorded one of the slowest times in Olympic history, this man gave more heart than any of the other competitors.
Just a short year ago, he had never even swum, let alone race. His country had been invited to Sydney.

|
A．made his turn to start back pitifully |
B．was skillful in freestyle in the game |

3.What’s the best title for the passage?

As a boy，Tim was much influenced by books about the sea, but in fact by the age of fifteen he had decided to become a doctor rather than a sailor. His father was a dentist and as a result Tim had the opportunity of meeting many doctors either at home or elsewhere. When he was fourteen he was already hanging around the clinic of a local doctor where he was supposed to be helping to wrap up medicine bottles，but was actually trying to listen to the conversations taking place between the doctor and his patients in the next room.

I was dealing with very real suffering and on the whole making a success of it .”In California he taught the country people simple facts about medicine. He saw himself as a life-saver. He had proved his skills to himself and his ability to take decisions. Thus，while he was able to tell them what to do, he could feel he was serving them. After the war, he got married and chose to be a doctor in the countryside，working under an old doctor who was popular in the area，but who hated the sight of blood and believed that the secret of medicine was faith.

Life gets noisier every day and very few people can be free from noise of some sort or another. It doesn’t matter where you live—in the middle of a modern city, or a faraway village—the chances that you will be disturbed by jet aero planes, transistor radios, oil-powered engines, etc. are almost everywhere.We seem to be getting used to noise, too. Some people feel quite lonely without background music while they are working.
Scientific tests have shown that total silence can be very frightening experience for human beings. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums(耳鼓).The noise level in some disco is far above the usual safety level for heavy industrial areas.
One recent report about noise and concentration(专心) suggested that although a lot of people say that any noise disturbs their concentration, what really affects their ability to concentrate is a change in the level of noise. It goes on to say that a background noise, which doesn’t change too much (music, for example) may even help people to concentrate.

Do fight against painting pollution
Do you know what kind of things the young people are reading? More and more 21_ and teachers have noticed another kind of pollution, which comes from the printed papers 22 on streets.
These printed things 23 newspapers but have hardly anything to do with _24_. You can only find reading materials badly made up there—some are too strange for anyone to 25 ; others are frightening stories of something _26_. However, many of the young readers are getting interested in such 27 reading, which 28 them what they should pay for their breakfast and brings them nightmares and immoral ideas in 29 . Homework is left 30 and daily games lost.
These sellers stand about on streets selling their papers well. The writers, publishers and printers, 31 they are, we never know, are 32 their silent money.
The sheep-skinned wolf’s story seems to have been forgotten once again. Why not 33 this kind of thing? Yes, both teachers and parents have asked each other for more strict control of the young readers. 34 , the more you want to forbid it, the more they want to have a look at it. 35 you may even find several children, driven by their curious natures, 36 one patched paper, which has traveled from hand to hand.
It really does 37 to our society. It has already formed a sort of moral pollution. The 38 teachers and parents need more powerful support in their protection of the young generation. At the same time, the young 39 need more interesting books to help them 40 those ugly paper.
