     In seventh grade, Brittany Blythe dreamed of being a cheerleader. Her school's coaches were less

than enthusiastic. "They said, 'I don't know how you'll be able to do it,' she recalls. "'You won't be able

to do it. '"

     But Brittany, now a junior at Strath Haven High School near Philadelphia, persisted(坚持). And when

the junior team cheerleaders won a tournament last year, she was right there, dancing and cheering with

the rest of the team.

     Not bad for someone whose legs were cut off below the knee when she was two years old.

Brittany, 18, was born without shinbones(胫骨)-"just blood and muscle tissue", as she puts it. When she

tried to walk, her legs twisted.

     After the operation, she adapted quickly. "From day one, I basically jumped up and wanted to do

everything," she says. Prosthetic legs(假腿) allowed her to move around upright, but too slowly to keep

up with her friends. Brittany's solution: take the legs off and walk on her knees-sometimes she still does

when safety and comfort permit.

     She's rarely daunted. Other children laughed at her through the years, especially in junior high school,

but she says the challenge only made her stronger. Now she's trying to convince her coaches to let her

remove the prostheses and be a flyer, the cheerleader who's thrown in the air and caught by her

teammates.

     Brittany doesn't think her problems are more difficult than the next person's. "My disability was the

first thing I had to get through, and that's going to prepare me for the future," she says. "It's all just a test:

If someone throws you a curve ball(给你出难题), what are you going to do?"
