听力原文： The results of the municipal elections in Italy in which the governing coalition lost ground to parties on the left and right attracted considerable attention in today's British newspapers. It's the lead story for the Financial Times, which focuses on the sharp falls on the Milan stock exchange and says the nervousness in the financial markets reflected the view that fresh general elections would be held early next year amid increased political uncertainty.

The Scotsman says file results reflect the bewilderment of a people who are watching file abrupt disintegration of the country's post-war political and economic fabric. The Yorkshire Post says the results raise the perennial question of whether Italy is governable. And The Independent adds that there's little prospect of a convincing new party of the moderate centre right emerging in time for the elections to fill the political vacuum left by the discredited Christian democrats and socialists.

(33)

A．It won the elections easily.

B．It lost the elections completely.

C．It attracted considerable attention in newspapers.

D．It didn't cause the falls on the stock exchange.

Man has long wished to predict earthquakes. Recent findings indicate that reliable earthquake prediction is almost a reality. Before earthquakes occur, there frequently are changes in rock behavior. that affect the velocities of other earthquake waves passing through the rocks. The former Soviet seismologists have used earthquake waves from other unrelated earthquakes to meas- ure the alterations in wave speed through rocks around a fault zone. For months to years before a particular earthquake, the former Soviet scientists observed that the strained rock in the fault zone was deformed in a way that slowed other earthquake wave that passed through the zone. Similar behavior. has preceded earthquakes in California and New York.

Changes in electrical resistance, water pressure l rock motion, and leakage of gas also can accompany the lowering of wave velocity. Fractures in the fault zone apparently open, which leads to a lowering of water pressure. When the fractures are filled by underground water, the continuing stress on the rocks is also exerted on the water in pores, which contributes to pressure within the rocks and ultimately causes further fault movement and earthquakes.

These preliminary events have been observed and studied for many earthquakes. The larger the earthquake, apparently the longer the time during which the preliminary events take place. Careful observation and measurement of the early events will precede reliable forecasts. The preliminary events are most evident along normal and reverse fault systems, and strike-slip faults may not produce the same effect. Although earthquake forecasting is in its infancy, both American and the former Soviet scientists have been able to predict the occurrence of a few earthquakes.

Understanding of the causes of earthquakes has opened several possibilities for their control. Underground nuclear explosions in Nevada have released strain energy stored in certain rocks. In some instances, the shock wave from the explosion has raised the strain on nearby fractures and faults enough to initiate fault movement. All of the resulting earthquakes have been small, but a large earthquake could conceivably be initiated.

In the future, a situation may arise where it is desirable to deliberately initiate an earthquake near a heavily populated area because too large an amount of strain has accumulated on an active fault zone in the vicinity. If hazardous areas were left empty and if emergency services were standing at the ready, such action might be considered necessary to prevent a later much more damaging earthquake. However, the legal, environmental, and human problems would be large in- deed, perhaps too great for such action to be taken.

Another possibility for earthquake control is much more exciting. Increasing water pressures can initiate faulting, as was unintentionally demonstrated by a deep well at the U. S. Army' s Rock Mountain Arsenal near Denver, Colorado, in the early 1960s. Disposal of nerve gas wastes in the well triggered movement along deeply buried inactive faults in the region. The liquid waste reduced frictional resistance along fault flat surface in the rocks surrounding the well, leading to movement along the faults. Earthquake activity in the area connected closely with the times of pumping of wastes into the disposal well, as was demonstrated convincingly by a Denver geologist, David Evans. Strain energy stored along the fault flat surface was apparently released by the fluid injection.

Experiments by the U. S. Geological Survey in the Rangely oil field of northwestern Colorado have added to the experience gained from the study of the Denver earthquakes. The Survey geologists injected water in some of the Rangely wells, causing very small earthquakes. By withdrawing the water, the earthquakes were stopped.

Section B

Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.

In the atmosphere, carbon dioxide acts rather like a one-way mirror—the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from escaping. According to a weather expert's prediction, the atmosphere will be 3℃ warmer in the year 2050 than it is today, if man continues to' burn fuels at the present rate. If this warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several meters and severely flooding coastal cities. Also, the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere, possibly resulting in an alteration of earth's chief food-growing zones.

In the past, concern about a man made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet. But the weather experts are now paying more attention to West Antarctic, which may be affected by only a few degrees of warming, in other words, by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels.

Satellite pictures show that large areas of Antarctic ice are already disappearing. The evidence available suggests that a warming has taken place. This fits the theory that carbon dioxide warms the earth.

However, most of the fuel is burnt in the northern hemisphere, where temperatures seem to be falling. Scientists conclude, therefore, that up to now natural influences on the weather have exceeded those caused by man. The question is, which natural cause has most effect on the weather?

One possibility is the variable behavior. of the sun. Astronomers at one research station have studied the hot spots and "cold" spots (that is, the relatively less hot spots) on the sun. As the sun rotates every 27.5 days, it presents hotter or "colder" faces to the earth, and different aspects to different parts of the earth. This seems to have a considerable effect on the distribution of the earth's atmospheric pressure, and consequently on wind circulation. The sun is also variable over a long term: its heat output goes up and down in cycles, the latest trend being downward.

Scientists are now finding mutual relations between models of solar-weather interactions and the actual climate over many thousands of years, including the last Ice Age. The problem is that the models are predicting that the world should be entering a new Ice Age and it is not. One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inenia (惯性) of the earth's climate. If this is right, the warming effect of carbon dioxide might thus be serving as a useful counter-balance to the sun's diminishing heat.

A concentration of carbon dioxide in the atmosphere would______.

A．prevent the sun's rays from reaching the earth's surface

B．mean a warming up in the Arctic

C．account for great changes in the climate in the northern hemisphere

D．raise the temperature of the earth's surface
