　　阅读理解模拟练习Passage Four

　　National Aviation and Space Administration (NASA) and its partners in the Inter-national Space Station have agreed in principle to let a 28-year-old South African become the second paying tourist on the orbiting outpost, the U.S. space agency said on Tuesday.　　Internet magnate Mark Shuttleworth signed a contract on Dec.4 with the Russian Aviation and Space Agency(RASA) to fly aboard a Soyuz space taxi to the station in April 2002, almost exactly a year after U.S.millionaire Dennis Tito became the first to experience space as a paying guest.　　NASA spokeswoman Kristen Larson said by telephone: "We've agreed in principle to the flight of Mr. Shuttleworth. However, there are some final details that need to be taken of ." Larson would not say what details needed resolving , but said the station’s international partners--including the space agencies of Russia, Europe, Japan and Canada--had drafted a set of requirements for space travelers covering "physical ability, psychological ability, language ability" and "length and appropriateness of training."　　Outgoing commander Frank Culbertson of the space station said the new crew replacing his was going to be extremely busy. "The station is for workers, and it puts an additional burden on the crew to have people up here that are not doing science or conducting experiments that are productive. This is a workplace, a laboratory, a research facility," he said.　　Space Adventures chief Eric Anderson said he could not disclose what Shuttleworth was paying for the trip, but added that a Russian official had been quoted as saying the price was no worse than Tito’s fare, which was widely reported to be $20 million.
