Some scientists warn that ice near the Earth’s Poles may indeed be melting. This “polar meltdown” may be the first sign that the Earth is heating up. We could be in very serious trouble if this trend continues. It is estimated that a meltdown of as little as 10 percent of Antarctica’s ice would raise sea levels around the globe by 4 to 9 meters. Floods would cover low-lying regions and turn coastal cities like New York and New Orleans into real life underwater world.

Scientists first predicted in the 1970s that heat trapped in the Earth’s atmosphere could cause a polar meltdown. Many now believe that human activities are turning up the heat. When we burn fossil fuels like coal and oil, we add carbon dioxide(CO2) gas to the Earth’s atmosphere. Cutting down trees also makes CO2 levels raise because trees normally soak up CO2 to make food. Scientists say higher CO2 levels strengthen the “greenhouse effect” and could increase the Earth’s temperature. In fact, CO2 levels have risen by 30 percent since the Industrial Revolution of the 18th and 19th centuries.

Over the past three years, satellite measurements have shown a sea level rise of about a quarter inch worldwide. “If nothing is done to reduce fossil-fuel pollution and global warming, sea levels will rise even more.” says geologist Richard Alley.

But even Alley admits that a polar meltdown would take time. The ice in Antarctica and Arctic locks up nearly nine times the volume of water contained in all the world’s rivers and lakes. These are such big “ice cubes” and it would probably take thousands of years to melt them.

Another scientist Charles Bentley doesn’t think a meltdown will happen at all. “Even if warmer temperatures begin to melt polar-ice,” he says, “the excess moisture would most likely be redeposit as snow.” In other words, the melted ice would evaporate into the atmosphere, refreeze, and fall as rain and snow over the Poles.

What consequence of global warming is mentioned in the passage?

A. More tropical storms. B. More tropical diseases.

C. Changes in farm productivity. D. Coastal flooding.

Which of the following statements does the second paragraph support?

A. CO2 in the atmosphere cannot keep the heat from escaping into space.

B. The increase of CO2 gas may warm the planet and help to melt polar ice.

C. Cutting down trees helps to greatly reduce CO2 levels.

D. The end of the short-lived age of fossil fuels is already in sight.

Geologist Richard Alley most likely agrees that _______.

A. the sea-level rise can be prevented by cutting back on energy-consuming activities

B. the recent breaking off of ice blocks from Antarctica is just a natural part of a long-term cycle

C. Antarctica temperatures have significantly changed since the Industrial Revolution

D. the polar meltdown may be an accidental change of climate rather than a sign of global warming

Charles Bentley believes that a polar meltdown will not occur because _______.

A. governments around the world are beginning to reduce CO2 levels in the air

B. a melting of the polar ice cannot be achieved with the present technologies

C. the melted ice in the polar areas would change into snow and rain over the Poles

D. the sun’s heat would have no chance of being absorbed by the polar ice

In which paragraph does the author mention the immense quantities of polar ice?

A. In the second paragraph. B. In the third paragraph.

C. In the fourth paragraph. D. In the fifth paragraph.

Stepping into a pool of water is common enough, but who could ever imagine stepping into a pool of fish? In February of 1974, Bill Tapp, an Australian farmer, saw a rain of fish that covered his farm. How surprised he must have been!

What caused this strange occurrence? This is a question that had long puzzled people who study fish. The answer turned out to be a combination of wind and storm.

When it is spring in the northern part of the world, it is fall in Australia. Throughout the autumn season, terrible storms arise and rains flood the land. The strong winds sweep over Australia like huge vacuum cleaners (吸尘器), collecting seaweed, pieces of wood, and even schools of fish. Strong winds may carry these bits of nature for many miles before vacuum dropping them on fields, houses, and astonished people.

Although they seem unusual, fish-falls occur frequently in Australia. When Bill Tapp was asked to describe the scene of fish, he remarked, “They look like millions of dead birds falling down.” His statement is not surprising. The wonders of the natural world are as common as rain. Nature, with its infinite wonders, can create waterfalls that flow upward and fish that fall out of the sky.

What is this passage about?

A. A sad story. B. Australia’s northern part.

C. A rain of fish. D. The damage done by floods.

Fish-falls occur in Australia __________.

A. quite often B. on large farms

C. only in winter D. when the air is calm

The underlined word “infinite” is closest in meaning to “__________”.

A. easy B. difficult C. countless D. dangerous

第一节：阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
It is a beautiful day in June. The sun is hot. It's time to harvest strawberries (草莓),and the strawberry fields are full of people. These people are picking strawberry. They are not farmers, and they are picking fruit for fun. They can buy strawberries in a supermarket but it is cheaper to pick their own fruit. Strawberries from the farm are also flesher (更新鲜的). Most people also like to pick their own fruit because it is a pleasant way to spend the afternoon.
One little boy is walking between the rows of plants. He is picking the strawberries and eating them as fast as he can. Two young women in pretty dress and high-heeled shoes(高跟鞋)are getting out of their car. Now they are taking off their shoes. These women are taking a break from their work. They want to pick fruit and enjoy the sunshine.
56. What time of the year do the people in the passage pick strawberries?
A. Early spring.           B. Early autumn.          C. Early summer.        D. Early winter.
57. The people in the passage are picking fruit because they are ________ .
A. farmers working all day in the fields
B. looking for a pleasant way to spend the afternoon
C. poor and need the money
D. stealing the fresh fruit

Disposing (处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste disposal problem becomes increasingly difficult.
During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot as a dump site. Residents or trash haulers (垃圾拖运者) would transport household rubbish, rotted wood, and old possessions to the site. Periodically some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by. Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.
Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential neighborhoods. Long distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is nonexistent. Awareness (意识) of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people cannot longer pay to get rid of waste. The amount of waste, however, continues to grow.
Recycling efforts have become common place, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city's reusable waste.
64. The most suitable title for this passage would be_______.
A. Places for Disposing Waste     B. Waste Pollution Dangers
C. Ways of Getting Rid of Waste     D. Waste Disposal Problem
65. During the 18th century, people disposed their waste in many ways except for_______.
A. burying it     B. recycling it     C. burning it     D. throwing it into rivers
66. What can be inferred from the third paragraph?
A. Farm areas will continue accepting waste from the city in modern society.
B. There is cheap land to bury waste in modern society.
C. It is difficult to find space to bury waste in modern society.
D. Ways to deal with waste in modern society stay the same.
67. The main purpose of writing this article is to_______.
A. draw people's attention to waste management
B. warn people of the pollution dangers we are facing
C. call on people to take part in recycling programs
D. tell people a better way to get rid of the waste

Q&A

Question: I come from a poor family, and my parents do what they can to pay for my education. What I want to do is let my parents live a happy and comfortable life. Where can I find riches? Do I need to leave school and find a well-paid job?

Answer: You are a considerate child. 1 An African farmer heard tales about other farmers who discovered diamond mines. These tales excited the farmer so much that he could hardly wait to sell his farm and hunt for diamonds himself.

So he sold the farm and spent the rest of his life wandering the African continent, searching unsuccessfully for the gleaming （闪烁的）stones. 2

Meanwhile, back on the farm, the man who had bought his farm happened to be crossing a small stream on the farm one day. 3 He picked it up. It was a sparkling stone — a good size stone — and, admiring it, he later put it on his mantel（壁炉架）.

Several weeks later, a visitor looked closely at it, then he nearly became unconscious. He told the farmer it was one of the largest diamonds ever discovered. The farmer said that the stream was full of these brilliant stones, and his farmland was covered with them. 4

If the first farmer had taken time to study and prepare himself — to learn what diamonds looked like in their rough state w and to thoroughly explore the farm he had before looking elsewhere, his wildest dreams would have come true. 5

A．I’d like to give you some advice on how to find the riches.

B．Now do you have any idea of what you should do to find the riches?

C．Finally, he threw himself into a river and drowned.

D．However, something special he was carrying dropped into the stream.

E. Needless to say, the farm turned out to be the most productive diamond mine.

F. Before I answer your questions, I want to tell you a story.

G. Suddenly he saw something gleaming at the bottom of the stream.
