听力原文： TUVALU, a tiny country in the Pacific Ocean, has asked for help as it fears it will be swallowed up by the sea. Storms and huge waves are a constant threat and none of Tuvalu's nine little islands is more than five meters above sea level. Salt water is already entering the country's drinking water supply, as well as damaging plants that produce fruit and vegetable. Without urgent help, the country's days are numbered. But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy, best known for its canals, has sunk about 24 cm over the past 100 years.
Experts say that it will have sunk another 20-50 cm by 2050. A century ago, St. Mark's Square, the lowest point in the city, flooded about nine times a year. Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands. Tuvalu's rising sea level is caused by global warming. The average global temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10-25 cm in the last 100 years. The main cause of global warming is human pollution. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even warmer.

A．It is in the Atlantic Ocean.
B．It has almost been swallowed by the sea.
C．It consists of 9 islands.
D．It is famous for its canal.

听力原文： With the development of science, scientists have discovered more about the world. Scientists say world coastal areas must prepare now for a rise in sea levels. No matter what action is taken, scientists say there are already enough greenhouse gases in the atmosphere to cause a major warning. As a result, scientists and government officials are focusing on how society might adapt to rising sea levels, changing agricultural zones, changing climates and other problems.
Already, state and local governments along the coast of the United States are starting to plan for a possible longterm rise in the sea level, and a few have taken action to cope with it. Agricultural researchers are developing heat-resistant and draught-resistant crops that might replace traditional crops if the climate changes. How long it will take for maximum warming to be reached is uncertain because the oceans slow such warming. Most scientists expect the maximum warming to take place by the second half of this century.
If levels of greenhouse gases in the atmosphere double, sea levels will rise; estimates of the average rise are from 1.5 feet to 6.5 feet. Some leading experts expect a rise of I meter, a little more than three feet.
(33)
A．Pollution of coastal areas.
B．Rise in sea levels.
C．Exhaustion of sea resources.
D．Earthquakes and volcanoes.

听力原文： 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. At the same time, 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. As a result, scientists conclude that up to now natural influences on the weather have exceeded those caused by human being.

A．Releasing less and less carbon dioxide.
B．Continuing to burn fuels at the present rate.
C．Melting of ice caps in the poles.
D．The rising sea level several meters.

听力原文： The northern Italian city is slowly drowning—sea levels in the Adriatic are risi
ng, and high tides are becoming more frequent. (32)The Italian government is spending a large sum of 4. 5 billion euro on a controversial project to build floodgates across the entrance to the lagoon in which the city stands in an effort to keep the sea at bay.
点击查看答案
Italian experts are proposing a dramatic new solution to the watery threat facing the city of Venice. Rather than battling to keep the sea out—they want to use it to help raise the sinking island-city.
(33) The scheme would~ involve pumping huge quantities of sea water into the ground beneath Venice down 12 pipes each of which would be 700m long. The sea water would make the sand beneath the city expand lifting Venice by 30cra in 10 years.
(34)Now, a panel of engineers and geologists from the respected University of Padua have come up with the new scheme costing just a fraction of that—100m euro.
It says the plan would help raise Venice by almost as much as it has sunk over the past three centuries. The professor leading the project says it is not an alternative to the floodgates - but would work in collaboration with them. Be now wants to carry out a trial to see if the theory would work in practice.
Not everyone is convinced. (35) One expert—who helped stabilize the leaning Tower of Pisa—described the scheme as pure science fiction and warned it could damage the fragile structure of Venice. But the city's mayor is interested. He says it is time to look again at how to raise the city—and is convinced that the technology exists to make it a reality.
(33)
A．Building floodgates to keep the sea out.
B．Stopping the sea level rising.
C．Raising the sinking city of Venice.
D．Saving the city from flooding.

第10题
The recent, apparently successful prediction by mathematical models of an appearance of El
Nino—the warm ocean current that periodically develops along the Pacific coast of South America—has excited researchers. Jacob Blerkness pointed out over 20 years ago how winds might create either abnormally warm or abnormally cold water in the eastern equatorial Pacific. Nonetheless, until the development of the models no one could explain why conditions should regularly shift from one to the other, as happens in the periodic oscillations between appearance of the warm El Nino and the cold so-called anti-El Nino. The answer, al least if the current model that links the behavior. of the ocean to that of the atmosphere is correct, is to be found in the ocean.

It has long been known that during an El Nino, two conditions exist: (1) unusually warm water extends along the eastern Pacific, principally along the coasts of Ecuador and Peru, and (2) winds blow from the west into the warmer air rising over the warm water in the east. These winds tend to create a feedback mechanism by driving the warmer surface water into a "pile" that blocks the normal upwelling of deeper, cold water in the east and further warms the eastern water, thus strengthening the wind still more. The contribution of the model is to show that the winds of an El Nino, which raise sea level in the east, simultaneously send a signal to the west lowering sea level. According to the model, that signal is generated as a negative Rossby wave, a wave of depressed, or negative, sea level that moves westward parallel to the equator at 25 to 85 kilometers per day. Taking months to traverse the Pacific, Rossby waves march to the western boundary of the Pacific basin, which is modeled as a smooth wall but in reality consists of quite irregular island chains, such as the Philippines and Indonesia.
When the waves meet the western boundary, they are reflected, and the model predicts that Rossby waves will be broken into numerous coastal Kelvin waves carrying the same negative sea-level signal. These eventually shoot toward the equator, and then head eastward along the equator propelled by the rotation of the Earth at a speed of about 250 kilometers per day. When enough Kelvin waves of sufficient amplitude arrive from the western Pacific, their negative sea-level signal overcomes the feedback mechanism tending to raise the sea level, and they begin to drive the system into the opposite cold mode. This produces a gradual shift in winds, one that will eventually send positive sea-level Rossby waves westward, waves that will eventually return as cold cycle-ending positive Kelvin waves beginning another warming cycle.
One characteristic of the El Nino is
A．cold coastal water near Peru.
B．winds blowing from the west.
C．random occurrence.
D．worldwide effects.
