People have always been dreaming of going to the moon. As long as the year 1901, H. G. Wells, an English writer, wrote a book vividly describing a trip to the moon. On landing there, the explorers discovered that the moon was full of underground cities. Words failed to express their surprise when they spotted so many “moon people”. The “moon people” felt even more surprised. “Why,” they asked, “are you traveling to outer space when you don’t even use your inner space?”
H. G. Wells could only imagine a travel to the moon. In 1969, human beings really left their footsteps on the moon. People today know that there are no underground cities on the moon. However, the question that the “moon people” asked is still an interesting one. A growing number of scientists are seriously thinking about it.
Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The “Channel”, a tunnel connecting England and France, is now complete.
But what about underground cities? Japan’s Taisei Corporation is designing a network of underground systems, called “Alice Cities”. The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. A solar dome (太阳能穹顶) would cover the whole city.
Supporters of underground development argue that building down rather than building up is a good way to use the earth’s space. The space, they say, can be used for farms, parks, gardens, and wilderness. H. G. Wells’ “moon people” would second it. Would you?

G. Wells once went to moon himself. B．Underground cities are more comfortable. C．The solar dome is a necessary part of underground cities.D．More underground systems will be in place in .【小题5】What would be the best title of the text? A．Alice Cities — cities of the futureB．Space travel with H. G. WellsC．Enjoy living undergroundD．Building down, not upC
答案：
(答案→)C
解析：文章大意：本文主要讲述人类对地球地下的开发和利用。
【小题1】C 细节题。根据第一段On landing there, the explorers discovered that the moon was full of underground cities，可知登上月球，探索者发现月球满是地下城市，可知月球人住在地下城市。故C正确。
【小题2】B 词义推测题。it代指月球人提出的use your inner space “使用地球内部空间”的想法，故B正确。
【小题3】B 细节题。根据文章第三段可分别提到了“地下停车场”、“地下购物区”和“地下隧道”。故B正确。
【小题4】C 推测题。根据文章倒数第二段最后一句A solar dome (太阳能穹顶) would cover the whole city可以推测太阳能穹顶是地下城市的一个必要部分。故C正确。
【小题5】D主旨大意题。本文主要讲述人类对地球地下的开发和利用，故文章的标题用“Building down, not up”比较确当。故D正确。
