A l0-year-old boy, Edwin, decided to study judo(柔道) although he had lost his left arm in a car
accident since 2 years ago.
       He began lessons with an old Japanese judo master(师傅).  He did so well, but after three months
of training, the master taught him only one move.
       "Master," Edwin finally said, "shouldn't I be taught more moves?"
       "This is the only move you know, but this is the only move you'll ever need to know.  "the master
answered.
       Several months later, the master took him to his first tournament(锦标赛). In the first match, he
seemed to be nervous.  But after some time, his opponent became impatient.  Little Edwin used his one
move to win the match.  Unexpectedly, he went into in the final.
       This time, his opponent was bigger and stronger. For a while, Edwin seemed to be o-vermatched.
Considered that he might get hurt, the referee（裁判员）called a time-out. He was about to stop the
match when the master said, "No, let him go on."
       With the match resuming（重新开始），his opponent made a critical mistake: he dropped his
guard. Suddenly, Edwin used his move to pin（压住）him. The little boy had won the tournament.
       On the way home, little Edwin asked, "Master,I really don't understand how Iopponentt to catch your left arm. " won the tournament
with only one move?
       "You won for two reasons," the master answered, "First, you've almost mastered one of the most
difficult throws in all of judo. Second, the only known defense（防御措施）for that move is for your 
opponentt to catch your left arm. "
