7．The Australian government researchers did research on the eyesight and habits of 100seven-year-old children in Singapore and Australia．The research shows that sunlight is good for people's eyes．If you spend two or three hours playing outdoors each day，it is not easy for you to become short-sighted．
    Both groups spent a similar amount of time reading，watching TV and playing computer games．However，the Australian children spent an average（平均）of two hours a day outdoors-90minutes more than the Singaporean children．As a result 30% of the Singaporean children were short-sighted-this rate（比率）was ten times higher than Australian children．
    Dr．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'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 stop us from becoming short-sighted？Scientists believe that natural light has a special chemical（化学物质）．It can stops the eyeball from growing out of shape and stop people becoming short-sighted．
    So be outdoors．It doesn't matter if that time is spent having a picnic or playing sports．

Healthy Food Paris
Spinach+Oranges Although spinach（菠菜） has lots of iron，your body doesn't absorb（吸收） it well when spinach is eaten alone．But with vitamin（维生素） C by its side，this vegetable becomes a true hero．

Avocado+Tomato Tomatoes are a super food．Eat some avocado（鳄梨） at the same time and you've got a super super food，because the fat in the avocado helps the body absorb seven times more lycopene（番茄红素）．

Green Tea+Lemon Drinking several cups of green tea is a good habit，because it can protect your heart．But if you intake some vitamin C at the same time，it can't be better．The vitamin C in lemons helps your body absorb 13 times more catechins（儿茶酚） than it can get from tea alone．
