| Life is not easy, so I'd like to say "When anything happens, believe in yourself." When I was a young boy, I was so shy to talk to anyone that my classmates 1 laughed at (嘲笑) me. I was sad but could do nothing. Later, 2 happened, and it changed my life. It was an English speech contest (比赛). My 3 asked me to take part in it. What a 4 idea! It meant I had to speak before all the teachers and students of my school. " 5 , boy. Believe in yourself. You are sure to win the contest." Then Mother and I talked about many different topics. 6 I chose the topic "Believe in yourself", I tried my best to remember all the speech and practiced it 7 100 times. With the help of my mother, I did well in the contest. I could hardly believe myself when the 8 came that I had won the first place; I heard the cheers from the teachers and the students. Those classmates who once looked down on me, now all 9 "Congratulations!" to me. My mother hugged (拥抱) me and cried excitedly. Since then, everything has changed for me. 10 I do anything, I try to tell myself to be sure and I will find myself. This is not only for a person but also for a country. | ||||
