(探险者) landed on the moon, they discovered that the moon was full of underground cities. They expressed
their surprise to the"moon people" they met.In turn, the"moon people" expressed their surprise."Why," they
asked,"are you traveling to outer space when you don't even use your inner space?"
H. G. Wells could only imagine travel to the moon. In 1969, human beings really did land on the moon.
People today know that there are no underground cities on the moon. However, the qu- estion that the "moon
people" asked is still an interesting one. A growing number of acientists 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"Chunnel", a tunnel (隧道)
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 pubic 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.

the earth's space. The surface, they say, can be used for farms, parks, gardens, and wilderness, H. G. Wells
