Why should we learn to swim?
Firstly, swimming is a good exercise for our health. Indeed doctors say it is the best exercise, because in swimming all the muscles of the body are used.
Secondly, swimming gives great pleasure. How nice it is, on a hot dusty day in summer, to take off one’s clothes and dive into the cool water of a rive or the sea, and to swim and float until one feels enough.
Thirdly, swimming may sometimes mean all the different between life and death, we never know when we may be in danger from water. We got on a voyage, and the ship in wrecked; we go for a pleasure sail on a lake and the boat turns over; we slip as we are walking along the bank of a river, and half in the water. If we can swim, we have chance for saving our own lives, but if we cannot swim, we are pretty certain to be drowned. So for our own safety, we should learn to swim.
Lastly, if we can swim, we may be able to save other people from drowning. How sad it is to see a friend drowning before our eyes while we cannot help just because we cannot swim.

A leading biologist has found the angels and fairies that sit at top of Christmas trees did not get there under their own power.
Prof Roger Wotton, from University College London, found that flight would be impossible for angels with arms and bird-like feathered wings.  
"Angels cannot take off and cannot use powered flight,” said Prof Wotton. “They would need to be exposed to very high wind velocities at take off - such high winds that they would be blown away."
Some the world’s most famous religious paintings and architecture make most Americans believe in angels.
The study found that 68 per cent of the 36,000 adults thought that angels and demons (魔鬼) were at work in the world.
According to the latest study, angels lack the powerful muscles which allow birds to beat their wings.
Prof Wotton’s paper explores why there are so many stories about angels. “Angels are very powerful religious icons for people with faith. Their similarity to humans adds to their power. At the same time, they have wings on them because they are more than human. They take messages to heaven and therefore have to fly.” said the academic.

People have different ways of greeting each other. They might shake hands (握手), kiss or hug (拥抱). But do you ever wonder how dogs say hello?

If you are a dog lover, you already know the answer to this question. When you arrive home, your dog jumps up into your lap (大腿前部). It wags (摇摆) its tail, and sometimes gives you wet kisses.

Like humans, dogs have five senses (感觉): smell, touch, sight, hearing and taste. Humans use sight as the main sense for recognizing (认出) one another. But dogs have poor eyesight. They use smell to recognize others. A dog’s sense of smell is much better than a human’s. It is through its sense of smell that tells the differences between different people.

Dogs use smell to recognize other dogs, too. They tell the differences by the smell of pee (小便) and pooh (大便). When two dogs meet, they smell each other’s noses. Then they go side to side, and smell each other’s butts (屁股). By smelling its friend’s behind, a dog knows who it is with.

That is also why dogs smell everything they can on the road. By smelling grass, trees and signposts (路标), dogs know which other neighborhood dogs have been around.

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 belif 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 Australia 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 peoplegets 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 .
