Put your choice in the ANSWERSHEET.(30 points)全国硕士研究生入学考试英语(二)真题第 1 页,共 6 页2Passage 1It is all very well to blame traffic jams, the cost of petrol and the quick pace of modern life, but manners on theroads are becoming horrible. Everybody knows that the nicest men become monsters behind the wheel. It is all verywell, again, to have a tiger in the tank, but to have one in the drivers seat is another matter altogether. You mighttolerate the odd road-hog, the rude and inconsiderate driver, but nowadays the well-mannered motorist is theexception to the rule. (Perhaps the situation calls for a “Be Kind to Other Drivers” campaign, otherwise it may getcompletely out of hand.)Road politeness is not only good manners, but good sense too. It takes the most cool-headed andgood-tempered of drivers to resist the temptation to revenge when subjected to uncivilized behavior. On the otherhand, a little politeness goes a long way towards relieving the tensions of motoring. A friendly nod or a wave ofacknowledgment in response to an act of politeness helps to create an atmosphere of goodwill and tolerance sonecessary in modern traffic conditions. But such acknowledgments of politeness are all too rare today. Manydrivers nowadays dont even seem able to recognize politeness when they see it.However, misplaced politeness can also be dangerous. Typical examples are the driver who brakes violently toallow a car to emerge from a side street at some hazard to following traffic, when a few seconds later the roadwould be clear anyway; or the man who waves a child across a zebra crossing into the path of oncoming vehiclesthat may be unable to stop in time. The same goes for encouraging old ladies to cross the road wherever andwhenever they care to. It always amazes me that the highways are not covered with the dead bodies of thesegrannies.A veteran driver, whose manners are faultless, told me it would help if motorists learnt to filter correctly intotraffic streams one at a time without causing the total blockages that give rise to bad temper. Unfortunately, modernmotorists cant even learn to drive, let alone master the subtler aspects of roadsmanship. Years ago the expertswarned us that the car ownership explosion would demand a lot more give-and-take from all road users. It is hightime for all of us to take this message to heart.16.According to this passage, troubles on the road are primarily caused by_.A peoples attitude towards the road-hogB the rhythm of modern lifeC the behavior of the driverD traffic conditions17.The sentence “You might tol、erate the odd road-hog.the rule.”(Para.1) implies that_.A our society is unjust towards well-mannered motoristsB rude drivers can be met only occasionallyC the well-mannered motorist cannot tolerate the road-hogD nowadays impolite drivers constitute the majority of motorists18. By “good sense”, the writer means_.A the drivers ability to understand and react reasonablyB the drivers prompt response to difficult and severe conditionsC the drivers tolerance of rude or even savage behaviorD the drive

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.

What happened to Mir in 1997?
A:It ran out of its fund.
B:Its main computer system broke down.
C:It was completely damaged by fire.
D:Its reputation was ruined due to power failures.

答案:B
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。
