In 1901, H.G. Wells, an English writer, wrote a book describing a trip to the moon. When the explorers landed on the moon, 61.他们发现月亮上到处都是地下城市. They expressed their surprise to the “moon people” they met. In turn, the “moon people” expressed their surprise. “Why,” they asked, “are you travelling to outer space when you don’t even use your inner space?”

H.G. Wells could only imagine the travel to the moon. In 1969, human beings did land on the moon. 62. 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. 63. 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, 64. 有许多地下购物区. The “Chunnel”, a tunnel connecting England and France, is now completed.

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 say that building down rather than building up is a good way to use dying Earth’s space. 65. They say the surface can be used for farms, parks, and gardens. H.G. Wells’ “moon people” would agree. Would you?
