Long long ago, there was a girl called Nuwa. Her father was Emperor(皇帝) Yan and he loved her very much. They often played together, and she also loved her father very much. One day, she had a wonderful time. Then she swam in the sea. She was too tired to swim and she was drowned(淹死). Because she wanted to see her father then she changed into(变成) a bird. She put some stones(石头) into the sea day after day and changed the sea into the land. She made a wish, and she would like to play with her father again.

Do you know why different animals or pests(昆虫)have their special colors? Colors in them seem to be used mainly to protect themselves.

Some birds like eating locusts(蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.

If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters(猎人). This is because they have the colors much like the trees.

Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid(液体)when it faces danger. While the liquid spreads over(散开), its enemies(敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.
