Spending two or three hours playing outdoors each day can reduce(减少)a child's chance of becoming short-sighted (近视), research shows. It challenges the belief that short-sightedness
is caused by computer use, watching TV or reading in weak light.
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 China and Australia. In all, 30% of the Chinese children were short-sighted. This percentage was ten times higher than Australian children.
Both groups spent a similar amount of time reading, watching TV and playing computer games. However, the Australian children spent an average of two hours a day outdoors-90 minutes more than the Chinese children.
Professor Ian Morgan 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 are 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 go outdoors. It doesn't matter if that time is spent having a picnic or playing sports.

3.How much time did the Chinese children spend outdoors every day?

4.What is the fifth paragraph mainly about?
A. Why people become short-sighted.

Antifreeze is a liquid(液体) that is added to water to keep it from freezing． When water freezes and turns to ice，it expands(膨胀)．The force of water expanding is so great that it will break the hardest metal．Water is used in car engines(发动机) to keep them cool while they run，and if this water is allowed to freeze in winter it can break the iron block of the engine．That is why antifreeze is necessary．
Water freezes at 0℃；the usual kind of antifreeze will not freeze until the temperature is－40℃．A mixture(混合物) of five parts of water and four parts of antifreeze will prevent freezing at－18℃；four parts of water and five parts of antifreeze reduce this to －22℃．
Alcohol is a kind of good antifreeze，but when the air is running it becomes hot and the alcohol boils away，so it must be changed very often．Most people use antifreeze that does not boil away when the engine is running．There are several chemicals that do this．One of the most popular is called ethylene glycol．
