Spending two or three hours playing outdoors each day can reduce the chance of becoming short-sighted, a research shows. It challenges the belief(信念) that short-sightedness is caused by computer use, watching TV or reading in weak light.
The Australian government researchers believe that the sunlight is good for people’s eyes. They compared the vision(视力) and habits of 100 seven-year-old children in Singapore and Australia. In all, 30% of the Singaporean children were short-sighted—this rate(比率) was ten times higher than Australian children.
Both groups spend a similar amount(数量) of time reading, watching television and playing computer games. However the Singaporean children spent an average (平均) of only half an hour a day outdoors—90 minutes less than the Australian children.
Professor Ian Morgan, from the Australian Research Council’s vision Centre, said, “Humans are naturally long-sighted, but when people begin to go to school and spend little or no time outdoors, the number of short-sighted people gets larger. We’re also seeing more and more short-sighted children in cities all around the world and the main reason may be that city children spend less time outdoors.
Daylight can be hundreds of times brighter than indoor light. But why does playing outside prevent us from becoming short-sighted? Scientists believe that natural light has a special chemical(化学物质) which stops the eyeball from growing out of shape and prevents people from becoming short-sighted.
So be outdoors. It doesn’t matter if that time is spent having a picnic or having sports.

One day a poor man was cutting a big piece of wood near a river. Suddenly his old axe(斧头) fell into the water. He felt very sad because he lost his only axe. Then all at once a beautiful fairy(仙女) came out and asked the man what was the matter.
“I have lost my axe.” he said. “It fell into the water when I was cutting the wood.” The fairy showed him a gold axe and asked, “Is this yours?” “No.” said the man.
The fairy then showed him a silver axe and asked again. “Is this yours?” “No.” again answered the man. Then she showed him the old axe.
“Yes, this is mine.” called out the happy man. “I know that well enough.” Said the fairy, “I only want to see if you can tell me the truth, and now I’ll give you the gold axe and the silver axe besides your own one.” The man with his old axe fell into the river.
The fairy came out and asked what was wrong with him.
The sad man only wanted the gold and silver axes.
The fairy found his lost axe for the man.
From the story, we know that an honest man may get more.
