题型:完形填空

I used to hate being called upon in class mainly because I didn’t like attention drawn to myself. And  1    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 laugh at me. Without the teacher who kept insisting on my “   6   for  it”, I wouldn’t have decided to give a try.
Getting up the courage to go to the tryouts was only the   7  of it! When I first started  8   the practice sessions (练习赛), I didn’t   9  know the rules of the game, not to mention 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 practice 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 motivating. 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 process (过程) — friends who respected my  16   to work hard and be a team player. I never had so much fun!   
With my    17    self-confidence comes more praise (赞扬) 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.
