Liu Yu, a fifteen-year-old boy from Shandong, a running star. He is on his school team and healways wanted to be a (职业的) runner when he grows up. However, his parents won' t allow him (train)so much. "Of course we want to see him (实现他的梦想)," says Mr. Liu. "And we know how much he loves running. Mywife and I have supported every one of his races. We have nothing against running! But we think our son needs to think about other (可能的)jobs. He' s getting older now,so he needs to think about what will happen if he doesn' t end up as a professional runner Liu Yu doesn' t really agree. " Well, I think I should (被允许)to decide for myself, hesays. "My parents have always taught me how important it is (work) hard at school and enter university. I understand this, but I' m serious about (run). It' s the only thing I' ve ever wanted to do. His parents believe that Liu Yu should study hard in the evenings so they don' t allow him to practice (run) at night. "Maybe he thinks it' s too strict or unfair," says Mrs. Liu. "But we think we' re doing the right thing. He needs to spend more time on his homework because it is difficult to become a professional sports star. " But Liu Yu still disagrees. "I know my parents care about me. They always talk about what (happen) if I don' t succeed. But I will! I' m a quick runner! I think I should be allowed to (做出这个选择)myself. Only then will I have a chance to achieve my dream. "
