    Each time I saw children 7 games, and heard their laughter, I 8 I were that age again. However, I remembered my parents' words—You must work very hard 9 have a good future. So I 10 up my pen and began to study hard again.

    I was still not 11 what competitions really meant. One day, I was 12 an English-speaking competition. When I went to the stage, I saw other students looking at me kindly.
