Last Christmas my older sister Jane got a unicycle (独轮脚踏车) she had requested. I thought it kind of strange, wondering why she would want something like that. She did ride and practice for a while, but eventually stopped.
Curious, I tried it, finding it very hard and thinking it impossible for a weak girl like me to learn. Since our dining room of our old house had low beams (屋梁), I used them like monkey bars to practice riding, which helped a lot. Because I thought it was really fun, I practiced every spare moment I had, teaching myself to go forwards, backwards and to turn. Practicing was something I loved to do in my spare time, but it did get discouraging when I fell. After months of practicing, I finally made it.
One morning, our teacher Maria excitedly announced that a school talent show was to be held to raise money for charity. She encouraged my classmates to sign up for it. I’m not always best in front of a crowd, which was why I was very nervous when I meant to put on my performance by doing a hula hoop (圈) and riding a unicycle on stage. But I overcame my fear and entered myself for the talent show, for which I practiced a lot in case I should mess up.
My routine (整套动作) was to do the hula hoop from my neck, down to my stomach, then to my knees. After that, I was to ride my unicycle forwards and backwards on stage. Lastly I would do the hula hoop while riding the unicycle. I was to do all this accompanied by my carefully selected music. I wondered what people from my seventh grade would think of my performance. With my friends inspiring me, I built up my confidence. On the night of the show, many people found out there was going to be a unicycle performance, so more came, even the headmaster.
Para. 1: I was both nervous and excited when it was my turn.
