阅读理解。 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 that I dare not talk to anyone. My classmates often laughed at me. I was sad but could do nothing. Later, something happened, and it changed my life. It was an English speech contest. My English teacher asked me to take part in 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 win.' Then my teacher 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 times. With my teacher's great love, I did well in the contest. I could hardly believe my ears when the news came that I had won the first place. I heard the cheers from the teachers and students. Those classmates who once looked down on me, now all said'Congratulations!' to me. My teacher hugged (拥抱) me and cried excitedly. Since then, everything has changed for me. When I do anything, I try to tell myself to be sure and I will find myself. This is true not only for a person but also for a country. 1. The classmates often laughed at the boy, because ______.
