Sometimes your biggest weakness can become your biggest strength. A boy, who had l  1  his left arm in a car accident, began his lessons with a Judo master(柔道大师). But after three months of hard t   2  , the master had taught him only one move. To know w  3  , the boy asked, ‘Teacher, shouldn’t I be good enough to learn more moves besides this one only?’ ‘But this is the only one you’ll ever need to have.’ was the teacher’s r _ 4  . Not quite understanding b   5   believing in his teacher, the boy continued. Several months later, the master took the boy to his first c   6   . The boy easily won his first two matches. The third match seemed to be more difficult, but after some time, his opponent(对手) became nervous and w   7   , the boy a   8  used his one move to win the match. Now his opponent was s   9   and more experienced. For a while the boy seemed weaker. The judge was about to stop the match. ‘ No .’ the teacher refused firmly (坚定地). The match went on. Just at this moment his opponent made a deadly m   10   . He dropped his guard when the boy gave him a sudden turnover: The boy was the final w  11   ! On the way home he was told why he could win: the only one known defense (防卫) for that most difficult move in Judo was for his opponent to take hold of his l   12   arm!
