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.
Part1
YP:What do you want to be when you grow up，Steve？
SS:I want to be an astronomer and visit stars.I 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.
Part2
SS:Do you think he wanted to travel into space in one of his rockets？
YP:I have no idea but I believe he looked forward to the first space flight by a Chinese astronaut.
SS: Yes. Now that China has sent satelites into space,I hope we' ll be the first to land on Mars.
That would really be something special and if I 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.
