Unit 4 Space Exploration Listening and Speaking & Reading and Thinking Brainstorm Who do you know are famous astronauts in China? Would you like to be an astronaut and how to be an astronaut?

How to be an astronaut 首先,你得有着一个学士学位,并且还是要能对航天工程中有所帮助的专业方向,比如说是机械工程、生物科学、物理科学、计算机或是数学等专业。 然后再要有长达三年的专业工作经验或至少1000小时的在喷气式飞机上作为机长飞行的时间,这些还是最基础的宇航员选拨标准。如果你幸运的都通过这些选拨成为一名候选人,你还要接受长达近一个周医疗工作者的跟踪。被选为宇航员的你并不一定是个全能的人,但是你却可能是位熟练操作宇宙飞船的机长,可能是医学出众的医者,可能是弹出优雅音乐的钢琴家,也可能是能做出美食佳肴的厨师。 Step 2:Thinking 9 First of all, you have to have a bachelor's degree in a major that will be useful in aerospace engineering, such as mechanical engineering, biological science, physical science, computer science, or mathematics. That would be followed by up to three years of professional experience or at least 1, 000 hours as a pilot in a jet, the most basic astronaut selection criteria. If you're lucky enough to be a candidate, you'll be followed by a health care worker for nearly a week. You don't have to be an all-powerful person to be chosen as an astronaut, but you might be an accomplished spaceflight captain, a brilliant doctor of medicine, a pianist who plays elegant music, or a chef who can cook great meals. Discuss with your partner about whether you would like to be an astronaut in the future and give your reasons. You know, I think being an astronaut would be cool. Do you want to work in space in the future? Step 3: Speaking Why do we see “SPACE: THE FINAL FRONTIER”? The journey into space took me into space THE space race between America and the Soviet Union was as much about ideological one-upmanship as extraterrestrial exploration. A new space race to the moon has an even less lofty goal: sightseeing. Two space-tourism companies are planning rival lunar missions that could see private individuals paying to fly to Earth's nearest celestial neighbour. Step 4:Thinking On June 19th Excalibur Almaz, a space company based on the Isle of Man, a British dependency in the Irish Sea, became the second company-after Space Adventures, an American space-tourism firm-to offer tickets for a commercial moonshot. Both firms are charging $150m a seat, a price that includes months of ground-based training. Neither is offering a descent to the moon's surface-just a lunar fly-by. Whereas the Americans won the first space race, the Russians are favourites for the rematch. Both Excalibur Almaz and Space Adventures are using Russian-made rockets and spacecraft. Space Adventures plans to re-engineer the veteran Soyuz craft that it has used to shuttle seven space tourists up to the International Space Station (ISS). Excalibur Almaz intends to refit two Almaz space stations that were originally made for the Soviet armed forces. The space-tourism business is famously long on hype but rather short, so far, on results. And both firms face big engineering challenges, to put it mildly. The easier task probably falls to Space Adventures, whose well-tested Soyuzcapsules-which have been flying, in one form or another, since the 1960s-require a beefier communications system, larger portholes (everyone wants a window seat, after all) and a better heat shield for re-entry. A separate booster rocket will be necessary to break the craft out of Earth orbit. Excalibur Almaz's bulky space stations will need a lot more work to convert into lunar spacecraft.
