The Mir Space Station
The Russian Mir Space Station,which came down in 2001 at last after 15 years of pioneering the concept of long-term human space flight,is remembered for its accomplishments in the human space flight history.It can be credited with many firsts in space.
During Mir's lifetime,Russia spent about US $4.2 billion to build and maintain the station.
The Soviet Union launched Mir,which was designed to last from three to five years,on February 20, 1986,and housed 104 astronauts over 12 years and seven months,most of whom were not Russian.In fact, it became the first international space station by playing host to 162 people from 1 1 countries.From 1995 through 1998,seven astronauts from the United States took turns living on Mir for up to six months each.They were among the 37 Americans who visited the station during nine stopovers by space shuttles.
The more than 400 million the United States provided Russian for the visits not only kept Mir operating,but also gave the Americans and their partners in the international station project valuable experience in long-term flight and multinational operations.
A debate continues over Mir's contributions to science.During its existence,Mir was the laboratory for 23,000 experiments and carried scientific equipment,estimated to be worth $80 million,from many nations.Experiments on Mir are credited with a range of findings,from the first solid measurement of the ration of heavy helium（氦）atoms in space to how to grow wheat in space.But for those favouring human space exploration,Mir showed that people could live and work in space long enough for a trip to Mars.The longest single stay in space is the 437.7 days that Russian astronaut Valery Polyakov spent on Mir from 1994 to 1995.And Sergie Avdeyev accumulated 747.6 days in space in three trips to the space station.The longest American stay was that of Shannon Lucid,who spent 188 days aboard Mir in 1996.
Despite the many firsts Mir accomplished,1997 was a bad year out of 15 for Mir.In 1997,an oxygen generator caught fire.Later,the main computer system broke down,causing the station to drift several times and there were power failures.Most of these problems were repaired,with American help and suppliers,but Mir's reputation as a space station was ruined.
Mir's setbacks are nothing,though,when we compare them with its accomplishments.Mir was a tremendous success,which will be remembered as a milestone in space exploration and the space station that showed long-term human habitation in space was possible.But it's time to move on to the next generation.The International Space Station being built will be better,but it owes a great debt to Mir.

参考答案和解析
答案：D
解析：
本篇文章主要介绍了和平号空间站经受的挫折和对人类的卓越贡献。
由第二段可知，和平号空间站是由苏联建造的。
第五段主要介绍了和平号空间站对科学作出的贡献，除了为人类探索空间提供实验场地和设备外，和平号空间站还证明人们可以在太空中停留足够长的时间。
A项在文中未提到，可直接排除；由第六段第四句可知，和平号空间站又被修好了，并未完全被摧毁，所以C项错误。其名声受损并不仅仅是因为电力故障，D项也不正确。由第六段第三句可知，B项正确。
由最后一段最后一句可知，正在建设中的国际空间站将比和平号空间站更完善，这表明各国联合操控的空间站的发展势头良好。
本篇文章介绍了和平号空间站对人类的贡献，最后一段又提到其历史意义，特别是最后一句又表明多国合作的空间站的发展离不开和平号空间站的贡献，由此可以推测出作者对和平号空间站是持赞许态度的。
