Life is full of chances and challenges. For students,       we don’t study hard，we will fall     other students. At first, I didn’t know     the word “exam” meant. Later, I knew an exam was a    of competition. In competitions, there were always    and losers. As I grew up, I got to know competitions well. In one’s life, there must be competitions, so people could    . Each time I saw children   games, and heard their laughter, I      I were that age again. However, I remembered my parents’ words--You must work very hard       have a good future. So I   up my pen and began to study hard again.
I was still not    what competitions really meant. One day, I was   an English-speaking competition. When I went to the stage, I saw other students looking at me kindly. I suddenly knew what the competition was. It was not as cruel   my teacher and parents told me. In fact, competitions were important and necessary.
I learned a lot   what I experienced. Now I understand15  about the world. Competitions are important for us all.
