Everyone needs friends. There is an old saying ,‘Friends are God's way of taking care of us.” But how do you find real friend and keep it?
   A Chinese writer Bai  Xun tells young students some smart ways to find friends. She says finding friendship is just like planting a tree. You plant the seed and take care of it to make it grow.  
   First, you should choose a friend. What makes a good friend? It is not because a person has money or good looks .A good friend should be kind and patient .For example , if you have a bad day, a good friend should listen to your complaints and do his or her best to help you. To make a friend, you can not be too shy. You should make each other happy and share your lives.
   But things cannot always be happy. Even the best friends have fights. What should they do when you have a fight with your friend ? You have to talk to him or her .When there is no one around , have an honest talk. If he or she doesn't want to talk, you could write a letter.
There are three steps to being friends again: Tell him or her how you are feeling, say what your friend has done wrongly, and explain why you did this or that . Remember that friendship is the most important thing in your life.

    Scientists have always believed that snails are not able to find their way home. But Briton Ruth Brooks, a retired teacher, has found that it is not true.

    Brooks began an experiment on snails after she got mad with the snails in her garden.

    The snails had eaten her vegetables. She didn't want to kill them, so she took them to another place. But she found they always seemed to come back.

    Brooks did an experiment. She marked the snails in her garden with nail polish(指甲油).

    She placed the snails in the area around her home and made notes of their movements.

    She found that snails have a strong homing instinct (本能); the longest returning snail traveled back 90 meters. Brooks has been named Britain's best amateur (业余的) scientist after her work won the BBC Radio 4 project, So You Want To Be A Scientist.

    She said, "I've always wanted to know whether the snails that eat my plants just come back when I move them, and if they do, what is their homing distance?

    "I would say on the evidence (证据) that it would be safe to take your snails away beyond 100m or even further. If you put them somewhere nice with some food, you can be almost certain that they won't come back."
