If you want to see a thing well, touching can help you to "see" it better.
Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass ball is. When you learn all these about the ball, you really see it well.
With your skin, you can feel better. For example, your fingers can tell the difference between two different coins in your pocket. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music.
All children soon learn what "Don't touch!" means. They hear it often. But most of us keep on touching things as we grow up. In shops, we touch things that we might buy. To se something well, we have to touch it. The bottoms (底部) of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a hard floor. All fe different under your feet.
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.
There are ways of learning to see well by feeing. 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.
If you want to see better, reach out and touch it. Then you will really see!
