When the world was a simpler place ,the rich were fat ,the poor were thin ,and right-thinking people worried about how to feed the hungry .Now ,in much of the world ,the rich are thin ,the poor are fat ,and right-thinking people are worrying about fatness.?
Evolution（進化）is mostly to blame. It has designed mankind to deal with lack ,not plenty .People are perfectly fit to store energy in good years to see them through lean ones. But when bad time never comes ,they are stuck with that energy ,stored around their expanding bellies.?
Thanks to rising agricultural productivity ,lean years are rarer all over the globe .According to the UN ,the number of people short of food fell from 920 m in 1980 to 799 m 20 years later ,even though the world's population increased by 1.6 billion over the period .This is mostly a cause for celebration .Mankind has won what was ,for most of his time on this planet ,his biggest battle：to ensure that he and his offspring had enough to eat. But every silver lining has a cloud ,and the result of prosperity is a new trouble.?
Fatness is the world's biggest public-health topic today—the main cause of heart disease ,which kills more ?people? these days than AIDS ,malaria（瘧疾）,war; the major risk factor in diabetes（糖尿�。�；heavily connected with cancer and other diseases .Since the World Health Organization labeled fatness an “epidemic（流行�。�”in 2000,?reports? on its fearful results have come thick and fast.?
Will public-health warnings ,combined with media pressure ,persuade people to get thinner ,just as they ?finally? put them off tobacco? Possibly .In the rich world ,sales of healthier foods are booming and new figures suggest that over the past year Americans got very slightly thinner for the first time in recorded history .But even if Americans are losing a few ounces ,it will be many years before the country solves the health problems caused by half a century's dining to overload .And ,everywhere else in the world ,people are still piling on the pounds .That's why there is now an agreement among doctors that governments should do something to stop them.?

Once an Englishman named Jack Brown went to Russia for a holiday. He stayed there for several months and then came home again. Some of his friends visited him a few days after he got back. “I had a very dangerous trip while I was in Russia.” Jack said to them. “I wanted to see a friend of mine in the country and the bad weather made me very late. So I was still travelling through a forest in sleigh<雪橇>when the sun went down. It was a long way from my friend’s house when about 20 wolves began to follow my sleigh. It was very dark in the forest. There was thick snow on the ground. It was cold, and there were no houses for miles and miles. First I heard the wolves, and the noise was terrible! The horses heard them, too. They were frightened and began running faster. Then I saw long, grey forms among the trees, and soon the wolves were near us. They were running very fast, and they didn’t seem to get tired like the horses.” “What did you do?” one of his friends asked. “When the wolves got very near,” Jack answered, “I put up my gun and shot the first wolf. The sleigh was moving about, but I hit the animal and killed it. Then all the other wolves stopped and ate it, so our sleigh got away from them for a few minutes.” “Then they finished their meal, and I heard them coming again. The moon was shining brightly on the snow, and after a few minutes I saw them among the trees once more. They came nearer again, and then I shot another of them, and the others stopped once more to eat it.” “The same thing happened again and again, and my horses became more and more tired and ran slower and slower until, after about two hours, only one wolf was still alive and following us.”

“Wasn’t it too fat to run?” one of his friends asked.

You are watching a film in which two men are having a fight.They hit one another hard.At the start they only fight with their fists.But soon they begin hitting one another over the heads with chairs.And so it goes on until one of the men crashes through a window and falls thirty feet to the ground below.He is dead!

Of course he isn’t really dead.With any luck he isn’t even hurt.Why？Because the men who fall out of high windows or jump from fast moving trains，who crash cars or even catch fire，are professionals.They do this for a living.These men are called stuntmen.That is to say，they perform tricks.

There are two sides to their work.They actually do most of the things you see on the screen.For example，they fall from a high building.However，they do not fall on to hard ground but onto empty cardboard boxes covered with a mattress(床墊)．Again，when they hit one another with chairs，the chairs are made of soft wood and when they crash through windows，the glass is made of sugar!

But although their work depends on trick of this sort，it also requires a high degree of skill and training.Often a stuntman’s(特技表演者的) success depends on careful timing.For example，when he is “blown up” in a battle scene，he has to jump out of the way of the explosion just at the right moment.

Naturally stuntmen are well paid for their work，but theylead dangerous lives.They often get seriously injured，and sometimes killed.A Norwegian stuntman，for example，skied over the edge of a cliff a thousand feet high.His parachute(降落傘) failed to open，and he was killed.

In spite of all the risks，this is no longer a profession for men only.Men no longer dress up as women when actresses have to perform some dangerous action.For nowadays there are stunt?girls too!
