英语翻译
Spending two or three hours playing outdoors each day can reduce a child’s chance of becoming short-sighted,a research shows.It challenges (挑战) the belief that short- sightedness is caused by computer use,watching TV or reading in weak light.
The Australian government researchers believe that 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 spent a similar amount of time reading,watching television and playing computer games.However,the Australian children spent an average(平均) of two hours a day outdoors—90 minutes more than the Singaporean children.
Professor(教授) 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 becoming short-sighted.
So be outdoors.It doesn’t matter if that time is spent having a picnic or playing sports.

最近一项研究表明,每天在室外进行两到三个小时的户外活动可以有效的降低儿童患近视的机会.这项研究挑战了儿童患上近视是由于过度用电脑看电视或是在暗光下阅读的观念.
澳大利亚政府研究工作人员认为太阳光对人眼有好处.他们在澳大利亚和新加坡比较了100名7岁儿童的视力与习惯.研究表明30%的新加坡儿童近视——这个比率高于新加坡儿童10倍.
这个小组花费同样的时间在这些儿童在阅读、看电视、玩电脑游戏进行研究.然而,澳大利亚儿童平均花费两个小时在户外运动——比新加坡儿童多90分钟.
日光比室内光亮数百倍,为何室外运动是儿童免于近视?科学家认为自然光中含有某种化学物质使眼球避免发生形变并且使儿童免于近视.所以,去室外吧,即使去野餐或运动也不要紧.
