     Adrian's "Amazing Race" started early when his parents realized that he, as a baby, couldn't

hear a thing, not even loud noises.In a special school for the hearingimpaired (听觉受损的),he

learned sign language and got to mix with other disabled   children.However, the sight of all the

disabled children communicating with one another upset his mother.She wanted him to lead a

normal life.So after speaking to an advisor, she sent him to private classes where he learned to

read lips and pronounce words.

     Later on, Adrian's parents decided to send him to a regular school.But the headmaster tried

to prevent them from doing so, saying regular school couldn't take care of a special student.His

parents were determined to take the risk and push him hard to go through his work every day

because they wanted to prove that, given the opportunity, he could do anything.Adrian made the

grade and got accepted.It was a big challenge.The pace (节奏)was faster so he had to sit at the

front of the class and really pay attention to the teacher, which wasn'talways easy.But he stuck to

it and did a lot of extra work after school.

     The efforts made by Adrian and his parents paid off.Adrian graduated with good grades and

got into a top high school.He also achieved a lot in life outside school.He developed a love for the

outdoors and went to Nepal to climb mountains.He even entered the World Yacht Race-being the

first hearingimpaired Asian to do so.

     But none of these achievements would have been possible without one of the most important

lessons from his mother. "If you believe in yourself and work hard, you can achieve greatresults,"

she often said.
