阅读理解。 Roy Yang, a reporter of English Learner, is interviewing some students. Here are what they are saying. Zhen Yii: The hero in my heart has to be Yang Liwei. He is the first person who has been sent into space in Shenzhou V in China. Besides Russia and the US, his trip to the space made China the third country to have successfully sent a person into space. Cai Ling: My hero is Jay Chou because he can not only sing and dance, he can also write songs. He is so popular among us young people. Wang Qi: I understand what Cai Ling is saying. He 's OK. But he's not a hero. In my mind, a hero is someone who has done something great. So Bill Gates, he's my hero. He invented Windows, which made computers so much easier to use. He makes a lot of money. But he gives a lot of it away to help others, and it really surprised me a lot. Lin Jun: My hero? You never guess it. He's my father. My father knows everything. He can help me with my study.
