语言素材：
A great Chinese scientist
Father of the Chinese space programme
Yu Ping(YP) is talking to her friend Steve Smith(SS) about Qian Xuesen and his work as a rocket scientist.
Part 1
YP:What do you want to be when you grow up, Steve?
SS:I want to be an astronomer and visit stars.1 wish to visit Mars one day.
YP:I think I'd like to work in the space industry too. I'd like to be a rocket scientist like Qian Xuesen.
SS:What did he have to do to become a rocket scientist?
YP:Well, he first studied at university to be an engineer. Later he went to America to study for his doctor's degree. It was then he began to work on rockets.
SS: So it was lucky for our space programme that he came back to China.
YP:Very much so. There was no work on space rockets in China before his institute to design and build rockets to go into space.
Part 2
SS: Do you think he wanted to travel into space in one ofhis rockets?
YP:I have no idea but I believe he looked forward to the first space flight by a Chinese astro-naut.
SS: Yes. Now that China has sent satellites into space, I hope we'll be the first to land on Mars.That would really be something special and ifl were that astronaut I would put Qian Xuesen's picture on Mars to show how much we admire his work.
YP: Indeed. He is rightfully called the father of the Chinese space programme. He is my hero and this is why I want to be a rocket scientist.
SS: Well, we'd better get on with our homework. We need good grades to get into university.
YP: Right you are. See you, then.
SS: See you.
