Here's a short story:

Hellen Keller was born in 1880 in the USA. When she was about 19 months old, she got very ill. After many weeks, the doctor told her parents, "Your daughter is better, but now she can't see and she can't hear." Her mother and her father were very sad. After a few years , things got worse. There was no way for Helen to speak to other people. She heard nothing. She didn't understand anything. Then one day a teacher came. Her name was Anne Sullivan. She lived with Helen and her family. The teacher helped Helen learn words. Helen was a very bright child and soon she learned to spell her first word. When she was older, she went to college . Helen was a very old woman when she died. The world remembers her today as a brave and wonderful person. She was blind and deaf, but she found a way to see and hear. It helped many people in the world. (End of story)
