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 Russ
4、ian 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 w
5、as 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 th
6、at 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 in
7、dustry 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 t
8、ourists. 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 De
9、stination 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 sp
10、ace 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 f
11、ew 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 NAS
12、A 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 thou
13、sands 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
16、a 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
18、into 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 t
19、he 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 wha
21、t 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 spa
22、ce 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
23、traffic. 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 A

We have probably all had lectures pointing out that laziness is (36) 1, that it is
43、wasteful, and that lazy people will never amount to(有所成就) anything in life. But laziness can be harmful than that, and it is often caused by more (37) 2reasons than the simple wish to avoid work. Some people who appear to be lazy are (38) 3 from more serious problems. They may be so (39) 4of their f
44、ellow workers that they are unable to join in any group task for fear of ridicule or fear of having their ideas (40) 5. These people who seem lazy may be paralyzed by a fear of failure that prevents fruitful work. Or other sorts of fantasies may prevent work; some people are so busy planning, someti
45、mes planning great deals or fantastic (41) 6, that they are unable to deal with; strictly speaking, they are (42) 7procrastinating-rescheduling their day. Laziness can (43) 8be helpful. Like procrastinators(拖延者), some people may look lazy when they are really thinking, planning, and researching. We
46、should remember that some great scientific discoveries occurred by chance or while someone was “goofing off“. Newton wasnt working in the orchard (果园) (44) 9. All of us would like to have some “lazy“ build the car or stove we buy, (45) 10. And sometimes, being “lazy“that is, taking time off for a restis good for the overworked student or executive.
