　　The hands, the eyes and the brain work together to make human beings different from other animals. No other animals have all three parts to work together. No animals can do what human beings can do. Humans can do many things and feel many things with the hand. The hand can hold onto things and make things because the thumb(拇指) works with the other fingers. This fifth finger is strong. Most animals don't have thumbs. The thumb can press against the other fingers. Without the thumb to press against the fingers, it is difficult to hold onto anything. The thumb and fingers can also fit the flat surface of a box and the curved(不平的) surface of a pencil. We can feel that something is hot or cold, soft or hard, smooth or rough. The hand, with the thumb and fingers, is one of the best tools we have.

　　Most animals see a flat picture. Their eyes can only see how high and how wide something is. Some animals see different pictures with each eye. Some don't see in color. Humans see one picture with both eyes working together. We can see how high and how wide something is. We can also see how far in front of or in back of something a thing is. The brain tells other parts of the body how to work. Some of the things the body does are automatic; that is, we don't have to think about them. For example, we don't have to think to make our heart beat or our stomach work. The brain tells the eyes and hands how to make useful and beautiful things. That is how human beings become toolmakers and artists. That is how humans can have richer and better lives than other animals.
