2、学习和生活经验。 （分数：30.00）_二、Part II Reading C(总题数：1，分数：71.00)Space Tourism Make your reservations now. The space tourism industry is officially open for business, and tickets are going for a mere $20 million for a one-week stay in space. Despite reluctance from National Air and Space Administration (NASA)
3、 , Russia made American businessman Dennis Tito the worlds first space tourist. Tito flew into space aboard a Russian Soyuz rocket that arrived at the International Space Station (ISS) on April 30, 2001. The second space tourist, South African businessman Mark Shuttleworth, took off aboard the Russi
4、an Soyuz on April 25,2002, also bound for the ISS. Lance Bass of N Sync was supposed to be the third to make the $20 million trip, but he did not join the three-man crew as they blasted off on October 30,2002, due to lack of payment. Probably the most incredible aspect of this proposed space tour wa
5、s that NASA approved of it. These trips are the beginning of what could be a profitable 21st century industry. There are already several space tourism companies planning to build suborbital vehicles and orbital cities within the next two decades. These companies have invested millions, believing tha
6、t the space tourism industry is on the verge of taking off. In 1997, NASA published a report concluding that selling trips into space to private citizens could be worth billions of dollars. A Japanese report supports these findings, and projects that space tourism could be a $10 billion per year ind
7、ustry within the next two decades. The only obstacles to opening up space to tourists are the space agencies, who are concerned with safety and the development of a reliable, reusable launch vehicle. Space Accommodations Russias Mir space station was supposed to be the first destination for space to
8、urists. But in March 2001, the Russian Aerospace Agency brought Mir down into the Pacific Ocean. As it turned out, bringing down Mir only temporarily delayed the first tourist trip into space. The Mir crash did cancel plans for a new reality-based game show from NBC, which was going to be called Des
9、tination Mir. The Survivor-like TV show was scheduled to air in fall 2001. Participants on the show were to go through training at Russias cosmonaut (宇航员) training center, Star City. Each week, one of the participants would be eliminated from the show, with the winner receiving a trip to the Mir spa
10、ce station. The Mir crash has ruled out NBCs space plans for now. NASA is against beginning space tourism until the International Space Station is completed in 2006. Russia is not alone in its interest in space tourism. There are several projects underway to commercialize space travel. Here are a fe
11、w of the groups that might take tourists to space: -Space Island Group is going to build a ring-shaped, rotating “commercial space infrastructure (基础结构)“ that will resemble the Discovery spacecraft in the movie “2001: A Space Odyssey. “Space Island says it will build its space city out of empty NASA
12、 space-shuttle fuel tanks (to start, it should take around 12 or so) , and place it about 400 miles above Earth. The space city will rotate once per minute to create a gravitational pull one-third as strong as Earths. -According to their vision statement, Space Adventures plans to “fly tens of thous
13、ands of people in space over the next 10-15 years and beyond, around the moon, and back, from spaceports both on Earth and in space, to and from private space stations, and aboard dozens of different vehicles.“ -Even Hilton Hotels has shown interest in the space tourism industry and the possibility
14、of building or co-funding a space hotel. However, the company did say that it believes such a space hotel is 15 to 20 years away. Initially, space tourism will offer simple accommodations at best. For instance, if the International Space Station is used as a tourist attraction, guests wont find the
15、luxurious surroundings of a hotel room on Earth. It has been designed for conducting research, not entertainment. However, the first generation of space hotels should offer tourists a much more comfortable experience. In regard to a concept for a space hotel initially planned by Space Island, such a
16、 hotel could offer guests every convenience they might find at a hotel on Earth, and some they might not. The small gravitational pull created by the rotating space city would allow space-tourists and residents to walk around and function normally within the structure. Everything from running water
17、to a recycling plant to medical facilities would be possible. Additionally, space tourists would even be able to take space walks. Many of these companies believe that they have to offer an extremely enjoyable experience in order for passengers to pay thousands, if not millions, of dollars to ride i
18、nto space. So will space create another separation between the haves and have-nots? The Most Expensive Vacation Will space be an exotic retreat reserved for only the wealthy? Or will middle-class folks have a chance to take their families to space? Make no mistake about it, going to space will be th
19、e most expensive vacation you ever take. Prices right now are in the tens of millions of the dollars. Currently, the only vehicles that can take you into space are the space shuttle and the Russian Soyuz, both of which are terribly inefficient. Each spacecraft requires millions of pounds of fuel to
20、take off into space, which makes them expensive to launch. One pound of payload (有效载重) costs about $10,000 to put into Earths orbit. NASA and Lockheed Martin are currently developing a single-stage-to-orbit launch space plane, called the Venture-Star, that could be launched for about a tenth of what
21、 the space shuttle costs to launch. If the Venture-Star takes off, the number of people who could afford to take a trip into space would move into the millions. In 1998, a joint report from NASA and the Space Transportation Association stated that improvements in technology could push fares for spac
22、e travel as low as $50,000, and possibly down to $20,000 or $10,000 a decade later. The report concluded that at a ticket price of $50,000, there could be 500,000 passengers flying into space each year. While still leaving out many people, these prices would open up space to a tremendous amount of t
23、raffic. Since the beginning of the space race, the general public has said, “Isnt that great when do I get to go?“ Well, our chance might be closer than ever. Within the next 20 years, space planes could be taking off for the Moon at the same frequency as airplanes flying between New York and Los An

At that time I ha
45、d just come back from Burma, where unemployment was only a word, and I had gone to Burma when I was still a boy and the post-war boom was not quite over. When I first saw unemployed men at close quarters, the thing that horrified and amazed me was to find that many of them were ashamed of being unem
46、ployed. I was very ignorant, but not so ignorant as to imagine that when the loss of foreign markets pushes two million men out of work, those two million are to blame. But at that time nobody cared to admit that unemployment was inevitable, because this meant admitting that it would probably continue. The middle classes were still talking about “lazy idle loafers on the dole“ and saying that “these men could all find work if they wanted to,“ and naturally these opinions affected the working class themselves. I remember the shock of astonishment it gave me, when I first met with tram
