7 阅读理解。 Last Saturday, our school organized a talent show to raise money for charity. It was a great success. Students took an active part in it and we raised 20,000 yuan in all. After the show I interviewed three students. First, I talked with Liu Li. In the talent show, she danced the ballet(芭蕾舞). "How long have you been dancing the ballet?" I asked. "For about six years." she answered. "Why do you learn it?" "I think it"s beautiful and I want to be a professional dancer when I grow up." Next I had a talk with Zhao Qiang. He played a piece of Mozart"s music. He played wonderfully. I asked, "When did you start playing the piano?" "Um, I"m twelve now and I have been doing it since I was five." he said. "Are you going to play the piano after you finish high school?" "Sure. My dream is to be a pianist." Finally, I asked Chen Yun, an 11-year-old girl. She sang us some folk songs(民歌). Her voice is very sweet. "Why are you interested in folk music?" I asked. "I admire Song Zuying and I want to be a singer like her. I have been singing folk songs since five years ago. I hope I can hold a singing concert in the future." she said. 根据短文内容，完成表格。 Talent How many years Dream Liu Li 1. ________ six 2. ________ Zhao Qiang 3. ________ 4. ________ to be a pianist Chen YunSinging folk songssince five years ago 5.________
