Disability doesn't mean inability．Although he has been blind since birth，18-year-old Joseph Chadbourne never feels different from his 90classmates at Akron's Firestone High School in Ohio，US．
Chadbourne walks with a cane （拐杖），and he is often arm-in-arm with a classmate who is happy to help him down the hallway or on the stairs．His textbooks and exams are in Braille（盲文），and he types his assignments and notes on a BrailleNote，a small computer hooked up to a printer．Because of his disability，he's permitted extra time on exams，but Chadbourne says he doesn't need it，as he completes his tests in the same amount of time as other students．
Teachers at Firestone have been impressed by Chadbourne，whom they say hasn't let his disability stop him from doing anything he wants to do．He's one of the top students in his class and he was on the swim team．
"He doesn't take，‘You can't do this，'for an answer，"Chadbourne's history teacher，Jill Regenos，told Akron Beacon Journal．
Chadbourne joined the swim team in his sophomore （高中二年级）year．His coach used a broom handle to poke （戳）him while in the water．This would give him the signal that he needed to flip （翻身）．
"It takes a month or so to get good timing，"Chadbourne said of the flips．"They tap and I immediately go into a turn．"
Chadbourne has even done his part to give back．He has taken part in an annual swim team fundraiser （募捐活动）to raise money for Akron Children's Hospital，swimming more than 10consecutive （连续的）hours this year，with only 10-minute breaks each hour．He also has tutored a younger blind student in Braille and reading fluency．
Chadbourne has this advice for other students with disabilities："Just don't let it stop you．If you put your mind to it，you can do anything．"
