I.阅读理解
       Antarctica experienced its hottest day on record earlier this month, peaking at 64.9 degrees Fahrenheit. As a result, in just over a week, 4 inches of Eagle Island's snowpack melted - that's about 20% of the island's total seasonal snow accumulation.
       “I haven't seen melt ponds develop this quickly in Antarctica,” Mauri Pelto, a geologist at Nichols College in Massachusetts, told NASA's Earth Observatory. “You see these kinds of melt events in Alaska and Greenland, but not usually in Antarctica.” As Pelto noted, melt events like this are quite rare for Antarctica, even during the summer. It's one of the coldest places on Earth.
       This heat wave was the result of continuous high temperatures, he said, which almost never occurred on the continent until the 21st century. It's the kind of weather event that grows increasingly common as global temperatures rise.
       This month, high pressure over Cape Horn in Chile islands allowed warm temperatures to build up and travel. Antarctica's northernmost part is typically protected from these high temperatures due to strong winds that cross the Southern Hemisphere, but those winds were unusually weak and couldn't stop the high temperatures from penetrating (穿透) the continent's northern tip, NASA reported.
       Ice caps in Antarctica are already melting rapidly due to heat - trapping gas pollution from humans. Rising sea levels could be catastrophic for the millions of people who live along the world's coasts: Antarctica's ice sheets contain enough water to raise global sea levels by nearly 200 feet, according to the World Meteorological Organisation.
       And earlier this month, a massive iceberg along the western edge of Antarctica broke off from the Pine Island Glacier. The 116 square mile - chunk of ice likely fell apart as a result of warmer sea temperatures, and it's evidence that the glacier is quickly responding to climate change, the European Space Agency said.

1. How does Mauri Pelto feel about the melting of icebergs in Antarctica?
A. Surprised.
B. Concerned.
C. Fearful.
D. Natural.
2. Why do high temperatures rarely reach Antarctica?
A. Because Antarctica is too far away.
B. Because its icebergs are so big.
C. Because strong winds stop them.
D. Because it is in the Southern Hemisphere.
3. What would happen if the Antarctic icebergs all melted?
A. The earth would become even warmer.
B. People would have plenty of fresh water.
C. The sea levels would rise by 200 metres.
D. Many coastal areas would be flooded.
4. What is the main idea of this text?
A. Coastal residents are at risk.
B. Antarctic icebergs are melting fast.
C. The earth is suffering from pollution.
D. Antarctica holds huge amounts of water.

答案： 1.A 推理判断题。根据第二段中莫里·佩尔托所说的话“I haven't seen melt ponds develop this quickly in Antarctica”和 “You see these kinds of melt events in Alaska and Greenland, but not usually in Antarctica.”可知，莫里·佩尔托认为南极洲冰山的融化速度非常快，这是罕见的。由此可推知，他对此感到很惊讶。故选A。
2.C 细节理解题。根据第四段中的“Antarctica’s northernmost part is typically protected from these high temperatures due to strong winds that cross the Southern Hemisphere”可知，南半球的强风阻挡了高温进入南极洲。故选C。
3.D 推理判断题。根据第五段中的“Rising sea levels could be catastrophic for the millions of people who live along the world's coasts: Antarctica's ice sheets contain enough water to raise global sea levels by nearly 200 feet”可知，南极洲冰盖拥有大量的水，可以使海平面大幅上升。由此可推知，如果南极洲的冰山都融化，许多沿海地区将会被水淹没。故选D。
4.B 主旨大意题。通读全文可知，文章围绕南极洲的冰山融化展开，介绍了南极洲经历了有记录以来最热的一天，为期一周多的热浪使南极洲鹰岛上20%的积雪融化，人类排放的温室气体近年来持续影响着南极洲的冰川。由此可推知，文章主要是关于南极洲的冰山正在迅速融化。故选B。
