| For each of us, life is not easy. So, when something unlucky happens, remember to believe in yourself. When I was young, I was 1 weak in French to pass the exam. I often got "E" or "F" on my papers. My classmates often 2 me in class. I was always sad but could do nothing. But later a French speech. contest 3 my life. And it also changed my views on everything. It was a Wednesday afternoon ; my father asked me to 4 a French contest. It was a terrible idea! My French grades were 5 bad. "Don't worry, dear. Believe in yourself and you' re sure to 6 the contest. " After that my father and I chose a right topic. Then I began to 7 my best to practice it again and again over100 times. Finally I was very 8 in the contest. When my French teacher told me I got the first prize, I could 9 believe my ears. And my father was too 10 to say a word. Then everything has changed for me. When I do anything, I always believe in myself and try my best to do it well. | |||
