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.

课文摘录:
布雷顿森林会议
随着第二次世界大战胜利之日的临近,防止战争悲剧重演,规划战后世界秩序厖许多有识之士主张建立有效的机制,以稳定世界经济。
当时很多人认为,世界经济的混乱、各国利己主义的政策是导致1929年世界经济危机加深的重要原因,并由此促使德、日、意走上使用武力重新瓜分殖民地的战争道路。
第二次世界大战打破了旧有的世界经济体系,以前所未有的力量冲击了欧洲的世界中心地位,使原有的世界经济格局发生了深刻的变化,各国亟待世界经济体系的重建。
战争结束后,德、意、日三国几乎成了一片废墟,国内经济百废待举;英、法等战胜国“赢得了战争,输尽了财富”,实力大为削弱;唯独美国的经济实力在战争中膨胀起来。美国企图按照自己的意志规划战后的“世界经济蓝图”,确立在世界经济中的霸权地位。


1944年夏,美、英、中等44个战时盟国的代表,在美国的新罕布什尔州布雷顿森林召开联合国货币金融会议,简称“布雷顿森林会议”。会议最终基本上按照美国的方案通过《布雷顿森林协定》,决定成立国际货币基金组织和国际复兴开发银行这两个国际货币金融组织,在此基础上建立的国际货币金融体系称“布雷顿森林体系”。《布雷顿森林协定》的签订是该体系建立的标志。
