Do you know why different animals or insects have their special colors? Colors are used mainly to protect themselves.
Why can’t some birds easily catch locusts（蝗虫）? It is because locusts change their colors together with the change of the colors of crops. When crops are green, locusts look green. But as autumn comes, locusts change to the same brown color as crops have. Some other insects with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives in the day 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 can’t be easily seen by hunters. This is because they have the colors much like the trees.
Have you ever noticed an even more strange thing? A kind of fish in the sea can send out black liquid when it faces danger. While the liquid spreads over, its enemies can’t find it. And it quickly swims away. So it has lived up to now though it is not strong at all.

Do you sometimes argue about what seems to you to be a simple fact? Do you argue whether it’s cold outdoors or whether the car in front of you is going faster than the speed limit (限速)?
If you get into such arguments, try to think about the story about the six blind men and the elephant. The first blind man who felt the elephant’s trunk (象鼻) said it was like a snake. The second who felt the elephant’s side said it was like a wall, while the third said it was like a spear( 矛 ) as he touched the animal’s tusk. The fourth, who took hold of the elephant’s tail, insisted that it was like a rope. The fifth man said it looked like a tree as he put his arms around one of the elephant’s legs. The last, who was tall and got hold of the elephant’s ears, said it was like a huge fan.
Each man’s idea of the animal came from his own experience. So if someone disagrees with you about a “simple fact”, it’s often because his experience in the matter is different from yours.
To see how hard it is for even one person to make up his mind about a “simple fact”, try this simple experiment. Get three large bowls. Put ice water in one. Put hot water in the second. Put lukewarm water (温水)in the third. Now put your left hand in the hot water. Put your right hand in the lukewarm water. Your right hand will tell you the water is cold. Your left hand will tell you it is hot.
【小题1】There were _______ blind man who were trying to tell what an elephant was like in the story.

D．the bowl

【小题4】What makes people think about simple facts differently?

A．People’s wrong ideas.

B．People’s different experience.
