I used to hate being called upon in class mainly because I didn’t like attention drawn to myself. And   1   otherwise assignen(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 a try.
Getting up t he courage to go to 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 the 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 prctice session, and not 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 moticating. Very soon the competitive   15  in me was winning over my lack of confidence. With time, I learned how to play and made friends in the   16    — friends who respect 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 and not 100 percent   20  I had the right answer. Now I have more self-confidence in myself.
