| During the winter, Fred Carpenter goes skiing (滑雪) just about every weekend. Sometimes he drives as far as three hundred miles to find the freshest snow. Fred has been skiing since he was seven years old. By the time he was twelve, he had won several junior championships. When he was thirteen, he lost his right leg in an accident. By the next season, Fred had learned to ski on one leg. "It's certainly a little harder this way," Fred says, "but the thrill is just the same." Now Fred is looking for other people like himself who love to ski. "It's time to organize some races!" he says. |
