     I was always tired at school, because I used to stay up late watching TV. I even fell asleep one day in my

history class, and when I woke up, the teacher was looking at me and laughing! I decided that minute to start

going to bed on time. It's kind of a drag missing the shows I like, but I can tell my body loves it-I feel so much

better!

     Last year, I didn't make the soccer team at school. I didn't want to try out again this year, but a few weeks before tryouts (选拔赛), I started kicking the ball around and practicing. When tryout day came, I decided to give it another shot. Guess what? I made the team!

     I'm deaf, so I've had more trouble playing sports than other people. But who wants to sit at home all the

time? I like to play basketball with guys in my neighborhood. I can't hear the ball bounce (弹起) or listen to the

guys call players, but I've taught them to use some sign language, and so far, we've been unstoppable!
