We see with our eyes and taste with our tongues（舌头）．Ears are for hearing，skin is for feeling and noses are for smelling．Would anyone say that ears can smell，or that tongues can see? Actually, yes．Paul Bach-V-Rita, a scientist at the University of Wisconsin，believes that the senses can be changeable．For example，a tongue can be used for seeing．The brain（大脑）,as

we know，is a complex organ（复杂的器官）．Even when part of it is hurt．it will try to carry out the same function by sending the function to another area of the brain。

    A college student was asked to take part in an experiment．In the experiment, his eyes were covered with a small video camera．The camera was connected to a long plastic line which went into his mouth．A computer would change the video's picture．The picture would travel through the plastic line as an electric current（电流），reaching the electrodes（电极板）inside the student's

mouth．The scientist would roll a ball towards his right side，left side，or centre, and the student would have to catch it．When the scientist rolled the ball，pain passed over the student's tongue．From the position（位置）of the pain on the tongue，the student reached out his hand and caught the ball．

If the brain can see a ball through a camera and a wet tongue，blindness and deafness can be overcome（克服）．

We live in a world of color. Everywhere in nature we    1    beautiful combinations of color green leaves, pink flowers,     2      sky, red berries and many more.       3    it is not surprising that colors affect our lives.

　　“If you want to see a thing well, reach out and touch it!”

　　That may seem a strange thing to say. But touching things can help you to see them better. Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth（光滑）and cool the ball is. You can feel how heavy the glass ball is. When you feel all these about the ball, you really see it. With your skin, you can feel better. For example, your fingers can tell the difference between two coins in your pocket. You can feel a little drop of water on the back of your hand, too.

　　All children soon learn what “Don't touch!” means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things as we might buy: food, clothes. To see something well, we have to touch it.

　　There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to（习惯于）them!

　　Most museums are just for looking. But today some museums have some things to touch. Their signs say, “Do touch!” There you can feel everything on show. If we want to see better, reach out and touch. Then you will really see!

A．you will have a strange feeling

B．you will learn how to reach out your hand

C．you can tell the difference of the things

D．you can tell what colours they are

A．try them on first

B．keep their right hands on them

C．ask about them

D．feel and touch them

(3)Why does it say“At first, it is not easy to feel these things”? Because __________.

A．the things are used by people, too

B．people feel the things too often

C．people know how to use the things

D．the things are easy to feel

A．Touching is more important than seeing.

B．Our feet, fingers, hands and skin can help us buy food.

C．People have to learn to see by feeling as they grow up.

D．Visitors can feel the things on show in some museums.
