六、信息还原。
阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。
For most of us, the Arctic(北极地区) and the Antarctic(南极地区) are very far places. The Arctic is the northernmost(最北的) region of the earth and it is the area around the North Pole. The Antarctic is the southernmost(最南的) region of the earth and it is the area around the South Pole. 1
Weather
The weather in both places is very, very cold. 2 Much of the ice there never melts(融化). Small pieces of ice are blown around by the wind and they look like falling snow.
What is under the ice?
One very big difference is what is under the ice. Water is under most of the ice in the Arctic. 3 The Antarctic is a large continent(大陆). It has plains(平原), valleys and mountains. They are covered with ice.
Animals
4 Polar bears live in the Arctic. Some foxes and wolves live there too. Most animals can't live in the Antarctic because it is too cold. However, penguins(企鹅) can live there. There are some animals that can live in both places, such as whales.
People
Many people live in the Arctic. There are towns and small cities on the land areas. In the Antarctic, it is so cold that nobody lives there for long. 5 They live in special buildings and don't spend much time outside.
A. Animals live in both places.
B. Both of them are covered with ice.
C. Land is under most of the ice in the Antarctic.
D. And I think we should protect wild animals here.
E. There are so many animals that will move to the cold place.
F. Scientists who study the Antarctic stay there while they are working.

【分析】
做信息还原题时，需先通读全文把握整体主题，再结合每个空白处的上下文语境，分析句子间的逻辑关系（如总起、衔接、对应主题等），逐一匹配选项：
1. 第一空前介绍北极、南极的位置，后分模块展开对比，需选总起句；
2. 第二空前讲两地天气寒冷，后提冰不融化，需选衔接天气与冰的句子；
3. 第三空前讲北极冰下是水，后讲南极是大陆，需选对应南极冰下情况的句子；
4. 第四空对应主题是“Animals”，需选与动物相关的句子；
5. 第五空前说南极无人长期居住，后提“他们住特殊建筑”，需选符合语境的主体（科学家）相关句子。
【解析】
1. 第一空：前文介绍北极、南极的基本位置，后文分“Weather”“What is under the ice”等模块对比两地，需总起句，G选项“Both of the places have a lot in common, but they are also different in many ways”符合总起逻辑，故选G；
2. 第二空：前文讲两地天气极冷，后文提到“Much of the ice there never melts”，B选项“Both of them are covered with ice”衔接天气冷与冰的存在，符合语境，故选B；
3. 第三空：前文说明北极冰下是水，后文指出南极是大陆，需对应南极冰下的情况，C选项“Land is under most of the ice in the Antarctic”符合，故选C；
4. 第四空：本段主题为“Animals”，需选与动物相关的句子，A选项“Animals live in both places”契合主题，故选A；
5. 第五空：前文说南极无人长期居住，后文提到“They live in special buildings”，F选项“Scientists who study the Antarctic stay there while they are working”说明是科学家在南极工作时停留，符合语境，故选F。
