D
Antarctica is the southernmost place on Earth, and it is larger than the United Sates and 95% of it is covered with ice. The ice is 5 kilometers thick at places and it never melts. At least that is what we thought, but let us keep it that way for now.
The ice seems to be alive as it works its way towards the seA． It forms an ice shelf over the water. The edge breaks away from the shelf and falls into the seA． From here it drifts. Now big pieces of ice become icebergs that can be 160 km long. They now drift north until they finally melt and become part of the ocean. This process is part of a bigger process which in turn forms a cooling system for Earth. This is so important that no country is allowed to control this areA． The treaty (agreement) signed by 12 countries at first and later joined by more, was to prevent any country harming the planet with irresponsible behavior.
The treaty basically states that:
Antarctica can be used for peaceful purposes only.
No country may build a military base there.
No country may do a nuclear test there.
No country may dump nuclear waste there.
Scientists working there will share their information.
Some other rules are there to protect the penguins and seals.
No dogs may run loose.
No planes may land near large groups of animals.
No guns, explosives, or tractors may be used near the animals.
Most important is that every member can inspect any of the other bases if he suspects that the treaty rules are being broken.
While the treaty is not foolproof（萬無一失的）, it does play a very important part in the protection of AntarcticA． The more people realize the effects that pollution has on this continent, the bigger the pressure will be on Governments to change the way they look at pollution.
69．Why was it important to sign a treaty for Antarctica?
A．Because the ice on Antarctica will finally melt into the ocean.
B．Because Antarctica is covered with 5 kilometers thick ice.
C．Because Antarctica balances the temperature of Earth.
D．Because there are many big icebergs in AntarcticA．
70．What is the process of the movement of ice in Antarctica?
A．Ice shelf---sea water---iceberg---ice.
B．Sea water---ice---iceberg---ice shelf.
C．Iceberg---ice shelf---ice---sea water.
D．Ice---ice shelf---iceberg---sea water.
71．What is included in the Antarctica treaty?
A．There is no secret research information in AntarcticA．
B．Dogs are not allowed to be raised in AntarcticA．
C．Waste can’t be thrown away in AntarcticA．
D．People can’t bring their guns to AntarcticA．

Antarctica and Environment
Antarctica has actually become a kind of space station – a unique observation post for detecting important changes in the world’s environment. Remote from major sources of pollution and the complex geological and ecological systems that prevail elsewhere, Antarctica makes possible scientific measurements that are often sharper and easier to interpret than those made in other parts of the world.
Growing numbers of scientists therefore see Antarctica as a distant-early-warning sensor, where potentially dangerous global trends may be spotted before they show up to the north. One promising field of investigation is glaciology. Scholars from the United States, Switzerland, and France are pursuing seven separate but related projects that reflect their concern for the health of the West Antarctic Ice Sheet – a concern they believe the world at large should share.
The Transantarctic Mountain, some of them more than 14,000 feet high, divide the continent into two very different regions. The part of the continent to the “east” of the mountains is a high plateau covered by an ice sheet nearly two miles thick. “West” of the mountain, the half of the continent south of the Americas is also covered by an ice sheet, but there the ice rests on rock that is mostly well below sea level. If the West Antarctic Ice Sheet disappeared, the western part of the continent would be reduced to a sparse cluster of island.
While ice and snow are obviously central to many environmental experiments, others focus on the mysterious “dry valley” of Antarctica, valleys that contain little ice or snow even in the depths of winter. Slashed through the mountains of southern Victoria Land, these valleys once held enormous glaciers that descended 9,000 feet from the polar plateau to the Ross Sea. Now the glaciers are gone, perhaps a casualty of the global warming trend during the 10,000 years since the ice age. Even the snow that falls in the dry valleys is blasted out by vicious winds that roars down from the polar plateau to the sea. Left bare are spectacular gorges, rippled fields of sand dunes, clusters of boulders sculptured into fantastic shapes by 100-mile-an-hour winds, and an aura of extraterrestrial desolation.
Despite the unearthly aspect of the dry valleys, some scientists believe they may carry a message of hope of the verdant parts of the earth. Some scientists believe that in some cases the dry valleys may soak up pollutants faster than pollutants enter them.
What is the best title for this passage?
A Antarctica and environmental Problems.
B Antarctica: Earth’s Early-Warning station.
C Antarctica: a Unique Observation Post.
D Antarctica: a Mysterious Place.
What would the result be if the West Antarctic Ice Sheet disappeared?
A The western part of the continent would be disappeared.
B The western part of the continent would be reduced.
C The western part of the continent would become scattered Islands.
D The western part of the continent would be reduced to a cluster of Islands.
Why are the Dry Valleys left bare?
A Vicious wind blasts the snow away. B It rarely snows.
C Because of the global warming trend and fierce wind. D Sand dunes.
Which of the following is true?
A The “Dry Valleys” have nothing left inside.
B The “Dry Valleys” never held glaciers.
C The “Dry Valleys” may carry a message of hope for the verdant.
D The “Dry Valleys” are useless to scientists.
