5. Before Reading_ Asimov_pop2 Before ReadingGlobal ReadingAfter Reading The Russian-born American scientist and writer Isaac Asimov, born on Jan. 2, 1920 and died on Apr. 6, 1992, wrote prolifically on a variety of subjects. Asimov's New Guide to Science (revised edition 1984) is ranked by critics among the best books of science written for nonscientists. Asimov was best known, however, for his many works of science fiction. The most famous include I, Robot (1950), The Foundation Trilogy (1951~1952), The Gods Themselves (1972), and Foundation's Edge (1982), which won both the Hugo and Nebula awards. Two volumes of his autobiography were published: In Memory Yet Green (1979) and In Joy Still Felt (1980). Later works include Foundation & Earth (1986), Prelude to Foundation (1988), etc. His family immigrated to the United States when he was three years old and settled in Brooklyn, New York. He entered Columbia University at the age of 15, and at the age of 18 he sold his story to Amazing Stories. Asimov received a doctorate in chemistry from Columbia University and taught biochemistry (1949~1958) at Boston University, remaining on the faculty there until his death. Detailed Reading

A. B. Growing numbers of Europeans are burrowing below ground to create houses, offices, discos and shopping malls. It is already proving a way of life in extreme climates: in winter months in Montreal, Canada, for instance, citizens can escape the cold in an underground complete with shops and even health clinics. And underground shopping malls are already common in Japan. Building big commercial buildings underground can be a way to avoid disfiguring or threatening a beautiful or environmentally sensitive landscape. Indeed many of the buildings which consume most land such as cinemas, supermarkets, theatres, warehouses or libraries have no need to be on the surface since they do not need windows.

A development of 194 houses which would take up 14 hectares of land above ground would occupy 2.7 while the number of roads would be halved. And an underground dweller has never paid a heating bill, thanks to solar panels and natural insulation. In the U.S., where energy-efficient homes become popular after the oil crisis of 1973, 10,000 underground houses have been built. A terrace of five homes, Britain’s first subterranean development, is under way in Nottinghanshire. Italy’s outstanding example of subterranean architecture is the Olivetti residential center in Ivrea.

10. Article1 Before ReadingGlobal ReadingDetailed ReadingAfter Reading Would you choose to live underground if you could gain many advantages from doing so? Weather would no longer trouble you. Temperature would remain the same all the year round. Artificial lighting could make the rhythm of our life uniform the whole world over. And the ecology of the natural world above ground would be greatly improved. While the prospect of moving underground may not be appealing to many people, Isaac Asimov is an enthusiast.

11. Article1-2_S Before ReadingGlobal ReadingDetailed ReadingAfter Reading The New Caves Isaac Asimov During the ice ages, human beings exposed to the colder temperatures of the time would often make their homes in caves. There they found greater comfort and security than they would have in the open. We still live in caves called houses, again for comfort and security. Virtually no one would willingly sleep on the ground under the stars. Is it possible that someday we may seek to add further to our comfort and security by building our houses underground — in new, manmade caves?

12. Article3-4_S Before ReadingGlobal ReadingDetailed ReadingAfter Reading It may not seem a palatable suggestion, at first thought. We have so many evil associations with the underground. In our myths and legends, the underground is the realm of evil spirits and of the dead, and is often the location of an afterlife of torment. (This may be because dead bodies are buried underground, and because volcanic eruptions make the underground appear to be a hellish place of fire and noxious gases.) Yet there are advantages to underground life, too, and something to be said for imagining whole cities, even mankind generally, moving downward; of having the outermost mile of the Earth’s crust honeycombed with passages and structures, like a gigantic ant hill.

Rain, snow, sleet, fog would not trouble the underground world. Even temperature variations are limited to the open surface and would not exist underground. Whether day or night, summer or winter, temperatures in the underground world would remain equable and nearly constant. The vast amounts of energy now expended in warming our surface surroundings when they are too cold, and cooling them when they are too warm, could be saved. The damage done to manmade structures and to human beings by weather would be gone. Transportation over local distances would be simplified. (Earthquakes would remain a danger, of course.)

On the surface, the tyranny of day and night cannot be avoided, and when it is morning in one place, it is noon in another, evening in still another and midnight in yet another. The rhythm of human life therefore varies from place to place. Underground, where there is no externally produced day, but only perpetual darkness, it would be artificial lighting that produces the day and this could be adjusted to suit man’s convenience.

Third, the ecological structure could be stabilized. To a certain extent, mankind encumbers the Earth. It is not only his enormous numbers that take up room; more so, it is all the structures he builds to house himself and his machines, to make possible his transportation and communication, to offer him rest and recreation.

Yet there are advantages to underground life, too, and something to be said for imagining whole cities, even mankind generally, moving downward; of having the outermost mile of the Earth’s crust honeycombed with passages and structures, like a gigantic ant hill. 1. How do you explain the word ‘palatable’? Palate, the top part of the inside of the mouth, was once generally held to be the organ of taste. So “palatable” means “pleasant to the taste”. Here used figuratively, it means “agreeable to the mind” or “acceptable”. It doesn’t seem to be a palatable suggestion to drive home in such bad weather; I prefer to stay until it clears up. 在这样的坏天气里开车回家似乎不是一个恰当的建议。我宁愿等到天晴。 2.

53. Before ReadingGlobal ReadingAfter Reading If the works of man were removed below ground — and, mind you, below the level of the natural world of the burrowing animals — man would still occupy the surface with his farms, his forestry, his observation towers, his air terminals and so on, but the extent of that occupation would be enormously decreased. Indeed, as one imagines the underground world to become increasingly elaborate, one can visualize much of the food supply eventually deriving from hydroponic growth in artificially illuminated areas underground. The Earth’s surface might be increasingly turned over to park and to wilderness, maintained at ecological stability. Detailed Reading turn over: 1) bring the bottom to the top or vice versa; rotate, cycle 2) think about; consider 3) transfer to another; give the control of sth. to sb. Match the definition above with the meaning of this phrase in the following sentences. His father had been turning the idea over in his mind for some time. The thief was turned over to the police. My stomach turned over. She turned over the problem in her mind. He has turned over his business to his brother. 2 ( ) 3 1 2 3

To reach the real countryside? One must travel horizontally for miles, first across city pavements and then across suburban sprawls.

Article12-13_W _restrict Before ReadingGlobal ReadingAfter Reading In an underworld culture, the countryside would be right there, a few hundred yards above the upper level of the cities — wherever you are. The surface would have to be protected from too frequent, or too intense, or too careless visiting, but however carefully restricted the upward trips might be, the chances are that the dwellers of the new caves would see more greenery, under ecologically healthier conditions, than dwellers of surface cities do today. However odd and repulsive underground living may seem at first thought, there are things to be said for it — and I haven’t even said them all. Detailed Reading restrict: vt. keep or confine within limits Speed is restricted to 30 mph in towns. The new law restricts the sale of hand guns. The speaker restricted her remarks to the new health care proposal. 市内车速每小时不得超过 30 英里。
