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 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(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 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 the earth’ s space.The surface,they say,can be used for farms,parks,gardens,and wilderness.H.G.Wells’s “moon people” would agree.Would you?

.
A.knew so much about the earth
