Life is not easy, so I’d like to say “When anything happens, believe in yourself.” When I was a young boy, I was 1_shy to talk to anyone. My classmates often _2_me.I was sad but could do nothing, Later, _3_happened, and it changed my life. It was an English speech contest. My mother asked me to _4_it .What a terrible idea! It meant I had to speak before all the teachers and students of my school. “Come on, boy. Believe in yourself. You are sure to 5_the contest.”Then mother and I talked about many different topics. At last I chose the topic “Believe in yourself.”I tried my best to remember all the speech and practiced it over 100 _6_.With my mother’s great love, I did _7_in the contest. I could hardly believe my ears when the news came that I had won the first place, I heard the cheers _8_the teachers and the students. Those classmates_9_once looked down on（看不起）me ,now all said “Congratulations!”to me. My mother hugged me and cried excitedly. Since then, everything has changed for me. When I do anything, I try to tell _10_to be sure and I will find myself. This is not only for a person but also for a country.
