PART I LISTENING COMPREHENSION (35 MIN)

SECTION A MINI-LECTUREDirections: In this section you sill hear a

mini-lecture. You will hear the lecture ONCE ONLY. While listening, take notes on

the important points. Your notes will not be marked, but you will need them to

complete a gap-filling task after the mini-lecture. When the lecture is over, you will be

given two minutes to check your notes, and another ten minutes to complete the

gap-filling task on ANSWER SHEET ONE. Use the blank sheet for note-taking.

听力原文： Going Underground Hello, everybody! Today’s lecture is

about a bold new idea—going underground to live a life in the future. At first

thought, it may not seem a pleasant suggestion. 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, because dead bodies are always buried underground. And the

volcanic eruptions make the underground appear to be a hellish place of fire and

noxious gases. It seems to be the place of an after life of torment. However, after we

explore all the advantages of living underground, it may seem to be a rather appealing

idea. The first advantage to an underground life is that weather would no longer be

important. Rain, snow, fog, hurricane, all these things are only phenomena of the

atmosphere, they would not trouble the underground world. Even temperature

variations are limited to the aboveground world and would not exist underground.

Whether day or night, summer or winter, temperatures in the underground world

would remain 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. And also the damage done to man-made structures and to

human beings by weather would be gone. Second, local time would no longer be

important. On the surface, there is always the natural and unavoidable shift between

day and night. It could not be avoided that when it is morning in one place, it is noon,

evening or even midnight in other places. The rhythm of human life therefore varies

from place to place. While in underground, there is no externally produced day. It is

artificial lighting that produces the day and this could be adjusted to suit man’s

convenience. The whole world could be on an 8-hour shift, starting and ending at the

same time. This is quite significant for businesses and public institutions. In a highly

mobile world, the universal time shift would save travelers lots of troubles. Air

transportation over long distances would no longer have to bring about “jet lag.”

Travelers landing on another coast or another continent would find the time of the

place they reach exactly the same as at home. Third, the ecological structure could

be stabilized. To a certain extent, it is mankind that makes the earth overcrowded. 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. All these things distort the wild,

depriving many species of plants and animals of their natural habitat. If the works of

man were removed below ground, man would still occupy the surface with his farms,

his forest, his observation towers, his air terminals and so on, but the extent of that

occupation would be enormously decreased. Indeed, as the underground world

becomes increasingly elaborate, even food could be supplied through 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.

Fourth, nature would be closer. It might seem that to go underground is to withdraw

from the natural world, but would that be so? Would the withdrawal be more complete

than it is now? Look at what we have now: We are working in crowded buildings that

are often windowless and artificially conditioned; even where there are windows, and

if one bothers to look up from his work and look out of the window, what is there to

see? Mostly man-made buildings spread all the way to the horizon. And to get away

from the city, to reach the real countryside, one must travel horizontally for miles,

first across downtown city and its terrible traffic, then across suburban sprawls. In an
