阅读理解。 Fans often only see the good fame(名声)of famous people. They see the happy smiles and great success of famous people. But usually they cannot see the hard work or the hours of practice behind the great success. Li Yundi, a great Chinese piano talent, talked with teens about his art and his job.'Of course, the job is hard work. You need to work hard to be professional. And you also have to play hundreds of concerts, meet fans, and listen to critics(评论家).' In 2000, when Li Yundi was 18, he won the top prize at the Chopin International Piano Competition in Poland. Li was the youngest and the first Chinese to win the prize. Born in Chongqing, Li began to play the piano when he was seven. His parents spent all their money and bought a piano for him-a luxury (奢侈品) in the 1980s in China. He worked hard. Every day, he played for eight hours or more at a piano school. He often played even after school. Li still can't play a beautiful tune without careful preparation (准备). ' You need to be ready (有准备的) on stage (舞台),' Li said.'People are waiting for you. Nobody knows whether (是否) you have slept enough, whether you have some problems in your life. But you need to play great music for your audience(听众).That's what they want to hear.' 1.
