In 1901, H. G. Wells, an English writer, wrote a book describing a trip to the moon. When the explorers landed on the moon, they discovered that the moon was full of underground cities.

They showed their surprise to the “moon people” they met. In turn, the “moon people” showed 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 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 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 would cover the whole city.

Supporters(支持者) of underground development say 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. Well’s “moon people” would agree. Would you?

C.Meeting the “moon people” again.

D.Traveling to outer space.小题3:What kind of underground system are already here with us?

A.Offices, shopping areas, power stations.

B.Tunnels, car parks, shopping areas.

C.Gardens, car parks, power stations.

D.Tunnels, gardens, offices.小题4:What would be the best title for the text?

A.Alice Cities—cities of the future.

B.Space travel with H. G. Wells.

C.Enjoy living underground.

D.Building down, not up.
