     Jean Driscoll can go faster in her wheelchair than the world's best marathoners (马拉松运动员) can run!

faster than the winning male runner! She competed on the track, too. She was second in the 800 meter

around in high school. Then she tried wheelchair race and was amazed. "Players crashed into each other and

fell out of their chairs," she says, "It was fun."

     Jean tried other wheelchair sports. At the University of Illinois, her wheelchair basketball team won two

national titles.

     Now Jean coaches and teaches. She tries to get people to set goals. "When I sign my autograph (亲笔签
