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 heahhy 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.

 Many different tribes live in the Ituri rain forest of Africa, but the Pygmies are the most unusual. Most of the men are not much more than four feet tall. They weigh only about eighty pounds. The women are even smaller and thinner. But in spite of the fact that they are small, these people are perfectly formed men and women.

      It is an exciting experience to visit a Pygmy encampment for the first time. Before you go, you must send word ahead that you are coming. Some friendly native or trader must take the message to the Tiki-Tikis. Otherwise the whole tribe will disappear into the depths of the jungle long before you have come close enough to be welcomed.

      The great Ituri rain forest seems cut off from the rest of the earth. There are living, dead, and dying trees on every side. Except where a clearing has been burned and chopped out, a man may live his whole life in the Ituri and never see farther than twenty yards.

      It takes sharp eyes to discover the almost hidden path to the Pygmy camp. The path is no wider than a small man’s foot. No sound breaks the silence in this part of the forest. There are no signs of people.

      The stranger must walk carefully. What appears to be a bent branch may prove to be a deadly snake. A spotted gold patch of sunlight may be a crouching leopard(豹).

Even the Pygmy camp comes as a surprise. The leafy shelters in which the little people live are hardly three feet high. They look so much like the surrounding undergrowth that they might easily be passed by. These houses contain no furniture of any sort. The beds are merely plantain leaves spread out on the earth floor. There are no cooking pots: food is eaten raw or smoked over a fire. Spears, bows and arrows are the only possessions of these people. When the tribe moves to a new camp there is nothing to carry except these weapons and babies too small to walk.

    A. the Pygmies are the shortest tribe worldwide

    B. the Pygmies are short but normal in mentality

    C. most of the Pygmy men are more than four feet

    A. are unwilling to communicate with people outside

    B. are very cruel and they will kill you with the spears

    C. are friendly to the tourists visiting them for the first time

    D. move so fast and often that can’t be caught up with easily

3. Which of the following word can describe the life of Pygmy?

    A. Their houses can’t be easily found in the hurt rain forest.

    B. Their houses, which are three feet high, are made of wood.

    C. Weapons and cooking pots are their most valuable possessions.

D. They are living in harmony with dangerous animals around.

 

“Dr.Papaderos,what is the meaning of life?”

The usual laughter followed,and people stirred(骚动)to go.Papaderos held up his hand and stilled the room and looked at me for a long time,asking with his eyes if I was serious and seeing from my eyes that I was.

“I will,answer your question.”

Taking his wallet out of his hip pocket,he fished into a leather billfold and brought out a very small round mirror,about the size of a quarter.And what he said went like this:

“When I was a small child,during the war,we were very poor and we lived in a remote village.One day,on the road,I found the broken pieces of a mirror.A German motorcycle had been wrecked in that place.

I tried to find all the pieces and put them together,but it was not possible,so I kept only the largest piece.This one,and,by scratching it on a stone.I made it round. I began to play with it as a toy and became fascinated by the fact that I could reflect light into dark places where the sun would never shine——in deep holes and crevices(裂缝)and dark closets. It became a game for me to get light into the most inaccessible places I could find.

I kept the little mirror,and,as I went about my growing up,I would take it out in idle moments and continue the challenge of the game.As I became a man,I grew to understand that this was not just a child’s game but a metaphor for what I might do with my life.I came to understand that I am not the light or the source of light.But light——truth,understanding,knowledge——is there,and it will shine in many dark places only if I reflect it.

I am a fragment(碎片)of a mirror whose whole design and shape l do not know.Nevertheless,with what I have I can reflect light into the dark places of this world——into the black places in the hearts of men—and change some things in some people.Perhaps others may see and do likewise.This is what I am about.This is the meaning of my life.”
