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. He can fix computers. And he plays basketball very well. He's so great!
