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