You should write at least 150 words according to the outline given below in Chinese: 1. 中国传统节日受到冷遇,西方节日日益升温已成为趋势
2、; 2. 形成这种现象的原因; 3. 你对这种现象的态度。(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 A
3、dministration (NASA) , 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
4、off aboard the Russian 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 pr
5、oposed space tour was 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 mil
6、lions, believing that 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
7、billion per year industry 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 dest
8、ination for space tourists. 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 go
9、ing to be called Destination 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
10、 trip to the Mir space 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 t
11、ravel. Here are a few 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 ci
12、ty out of empty NASA 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 t
13、o “fly tens of thousands 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
14、and the possibility 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, g
15、uests wont find the 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
16、Space Island, such 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
17、 from running water 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,
18、of dollars to ride 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
19、 to space will be the 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 o
20、f pounds of fuel to 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 a
21、bout a tenth of what 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
22、 push fares for space 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 tr
23、emendous amount of 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
