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．

1．How much time did the Singaporean children spend outdoors on average every day in the research?

A． 2 hours．          B． 90 minutes．       C． 1 hour．             D． 30 minutes．

2．What is the fifth paragraph mainly about?

A． Why people become short-sighted．

B． Why natural light has a special chemical．

C． Why playing outside is good for one’s eyesight．

D． Why daylight is much brighter than indoor light．

3．Which of the following is true according to the passage?

A． People will all become short-sighted after they begin to go to school．

B． Playing outdoors for 2 or 3 hours every day can help protect your eyesight．

C． Children in Australia are more likely to get short-sighted than those in Singapore．

D． If you spend two or three hours playing outside each day, you won’t get short-sighted．

In most situations, light helps us see．But nowadays humans are using too much of it so that it is in fact a kind of pollution．

When it comes to looking at the night sky, too much light makes it difficult for us to watch some of life’s most wonderful sights: stars, planets and even galaxies（星系）．

According to scientific research, about 2, 500 stars can be seen by the human eye without using any special equipment（设备）．But because of light pollution, you can only see 200 to 300 stars from today’s countryside, and no more than ten stars from a city．In most big cities, people cannot see the sky filled with stars like they did in their childhood．

Light pollution affects more than just our view of sky．Research shows that lots of nighttime light can harm wildlife, too．

When birds fly to another place over cities, they sometimes get lost by the brightness and fly in circles（圈） until they drop from tiredness．Sea turtles（海龟） need dark beaches for laying eggs, but they can’t find their ideal places because of those bright lights．

Too much light at night may even affect human health, but scientists are not sure of that． They are still learning more．

In order to prevent things from going worse, governments and some organizations are working to reduce light pollution．Many cities and towns have taken action to reduce the use of lights at night．Lights are used only when and where they are truly needed．They also shine lights down at the ground instead of up into the sky and use lower brightness levels．

Hopefully, in the near future, humans can enjoy the clear and beautiful sky again and all the wildlife will live a peaceful and undisturbed life, too．

I was in line waiting to pay．In line there were two people before me．A little boy was buying some rather strange clothes．He chatted with anyone who was interested in the clothes and soon we learnt that he was going to a kindergarten（幼儿园） party． He had done a great job of putting together interesting costumes．

I noticed that the little boy was paying mostly with change（零钱）．It seemed that he had robbed his pig bank（猪形储蓄罐）to do this shopping．However, the cashier told him he was short after counting all the money．The boy thought for a moment and said, “Please keep the shirt and I will come back with more money．

I didn’t even get a chance to give anything!”

I smiled at her and said, “You did your share, because it was your idea and you started all this．“ The little boy smiled and thanked us．We wished him the best and he left．I was left with a good feeling．I had seen the love and goodness of others all around me．The woman in front of me smiled and said, “It sure feels good to give, doesn’t it?” I smiled back and said, “Yes !”
