     I used to hate being called upon in class mainly because I didn't like attention drawn to myself. And   1   
otherwise assigned (指定) a seat by the teacher. I always   2   to sit at the back of the classroom.
     All this   3   after I joined a sports team. It began when a teacher suggested I try out for the basketball
team. At first I thought it was a crazy   4   because I didn't have a good sense of balance, nor did I have
the   5   to keep pace with the others on the team and they would tease me. But for the teacher who kept
insisting on my '  6   for it', I wouldn't have decided to give it a try.
     Getting up the courage to go the tryouts was only the   7   of it! When I first started   8   the practice
sessions, I didn't even know the rules of the game, much   9   what I was doing. Sometimes I'd get  10  
and take a shot at a wrong direction-which made me feel really stupid.  11 , I wasn't the only one "new"
at the game, so I decided to  12  on learning the game, do my best at each practice session, and not to be
too hard on myself for the things I didn't  13  "just yet".
     I practiced and practiced. Soon I knew the  14  and the "moves". Being part of a team was fun and
motivating. Very soon the competitive  15  in me was winning over my lack of confidence. With time, I
learned how to play and make friends in the  16 -friends who respected my efforts to work hard and be
a team player. I never had so much fun.
     With my  17  self-confidence comes more praise from teachers and classmates. I have gone from
" 18 " in the back of the classroom and not wanting to call attention to myself,  19  raising my hand-even
when I sometimes wasn't 100 percent  20  I had the right answer. Now I have more self-confidence in
myself.
