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.
【分析题】
案例：
教师演示实验并提问：让一张纸与一个小钢球同时从同一高度处开始自由下落，可以观察到什么现象？
学生：钢球先落地。
教师：对，这就是生活中观察到的现象。
教师演示实验：教师把刚才的纸揉成团，再与小球一起由静止开始从同一高度处同时下落，学生观察到什么现象？学生：几乎同时下落。
教师：这是因为空气阻力的影响。把纸揉成团时所受的空气阻力，要比一张纸摊开时小得多。
教师演示实验：教师拿出事先抽成真空（空气相当稀薄）的牛顿管，让管中的硬币、鸡毛、纸片、粉笔头从静止开始同时下落，学生观察到什么现象？
学生：同时下落。
教师：这就是自由落体运动。
教师板书——自由落体运动：物体只在重力的作用下从静止开始下落的运动。
问题：
