To read this page, you must use your eyes.The blind can read, too, but they must use them fingers. (76) Over 100 years ago in France, a young boy was play in his father’ s workshop. He (77) was making holes in a piece of leather (皮革) (78) ) with a pointed tool. All at once, the tool flied from his hands and struck his face. (79) This child, Louis Braille, had been injured (80) his eyes. Soon he was blind. In those days, few blind people could read. Then, years lat- er, Louis Braille had an idea. He remember (81) the holes he has once made in leather. If he (82) pushed the tool only part way through (83) leather, he could feel rised dots on the other (84) side. Using from one to five raised dots, he made up an alphabet (字母表). Today, many books are printing in (85) Braille.
