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 5 all the teachers and students of my school! "Come on, boy. Believe in yourself. You are sure to 6 ." Then mother and I talked about many different topics. At last I 7 the topic "Believe in yourself". I tried my best to remember all the speech and practiced it over 100 8 . With mother's great love, I did 9 in the contest. I could hardly believe my 10 when the news came that I had won the first place. I heard the cheers (赞美) 11 the teachers and students. Those classmates 12 once looked down on (瞧不起) me, now all said "Congratulations!" 13 me. My mother hugged me and cried excitedly. 14 then, everything has changed for me. When I do anything, I try to tell 15 to be sure and I will find myself. This is true not only for a person but also for a country. | ||||
