Humans have observed and explored the oceans since ancient times.But it wasn’t until the 19th century that the scientific study of oceans began.The first major scientific expedition,and the one that firmly established the field of oceanography,was the around-the-world voyage of H.M.S.  Challenger.Setting out from England in 1872,the Challenger spent almost three and a half years gathering a wealth of information about seawater,sea life,and the ocean floor.Major oceanographic expeditions since then have included the South Atlantic voyage of the German ship Meteor in 1926 and the Deep-Sea Drilling Project from 1968 to 1983.Many individuals also have played important roles in advancing our understanding of oceans,beginning with Matthew Fontaine Maury in the mid-1800s;his work on oceanography and navigation led to a uniform system of weather reporting at sea.Since Maury’s time,oceanography has progressed rapidly.Early oceanographers had to contend themselves with tossing buckets overboard to see what they might haul in.Today’s oceanographers are equipped with space images,supercomputer models,and deep-sea robots that can crawl along the seafloor.As they set goals for the future,some oceanographers even dream of doing research in permanently manned stations on the bottom of the oceans.

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?
【小题1】The explorers in H. G. Well’s story were surprised to find that the “moon people” ______.

A.knew so much about the earth
B.understood their language
C.lived in so many underground cities
D.were ahead of them in space technology
【小题2】What does the underlined word  (paragraph 3) “it” refer to?
A.Discovering the moon’s inner space.
B.Using the earth’s inner space.
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.
