Part II Reading Comprehension

　　Directions: There are 3 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet with a single line through the center.

　　Passage One：Questions 31 to 35 are based on the following passage.

　　At the bottom of the world lies a mighty continent still wrapped in the ice age and，until recent times， unknown to men.It is a great land mass with mountain ranges(山脉)whose extent and elevation are still uncertain.Much of the continent is a complete blank on our maps.Man bas explored，on foot，less than one percent of its area.

　　Antarctica differs fundamentally from the Arctic regions.The Arctic is a ocean, covered with drifting packed ice and hemmed(包围)in by the land masses of Europe，and North America.The Antarctic is a continent almost as large as Europe and Australia combined，centered roughly on the South Pole and surrounded by the most unobstructed(无限制的，不受阻挡的)water areas of the world-the Atlantic，Pacific，and Indian Oceans.

　　The continental ice sheet is more than two miles high in its centre;the air over the Antarctic is far more refrigerated than it is over the Acrylic regions.This cold air current from the land is so forceful that it makes the nearby seas the stormiest(多风暴的)in the world and renders unlivable those regions whose counterparts at the opposite end of the globe are inhabited.Thus，more than a million persons live within 2,000 miles of the North Pole in an area that includes most of Alaska，Siberia，and Scandinavia-a region rich in forest and mining industry.Apart from a handful of weather stations，within the same distance of the South Pole there is not a single tree，industry or settlement.
