Seen from space, the astronauts tell us, the most distinctive feature of our planet is the ice sheet of Antarctica which “radiates light like a great white lantern across the bottom of the world”. This ice sheet covers 5,500,000 square miles (an area greater than the United States and Central America combined); it averages more 7,000 feet in thickness; it contains more than 90 per cent of the world’s ice and snow, and if suddenly it melted the oceans would rise to such a height that every other person on earth would be drowned. Antarctica is in fact our planet’s largest and most spectacular natural phenomenon
authority to his explanation. f) He also uses parallel structures as an effective way of
describing what life in the Antarctic.
In this sort of cold if you try to burn a candle the flame becomes obscured by a hood of wax, if you drop a steel bar it is likely to shatter like glass, tin disintegrates into loose granules, mercury freezes into a solid metal, and if you haul up a fish through a hole in the ice within five seconds it is frozen so solid that it has to be cut with a saw.

Part 3 The reason why Antarctica is uninhabitable
Part 2: Comparison between the Arctic and the Antarctic
①People used to regard the Arctic and the Antarctic as much alike. ②In fact their differences outweigh their similarities./ ③ The Arctic is closely hemmed in by the populated landmasses of Europe, America and Asia; the Antarctic in contrast is in splendid isolation, divided from the nearest land by vast reaches of the most tempestuous seas on earth. /④Another big difference is the climate. ⑤We are so inclined to think of both the Arctic and Antarctic as cold, that we tend to forget how much colder the latter is. /⑥North of the Arctic Circle tens of thousands of families live in comfort all the year round; hundreds of children are born every year. ⑦South of the Antarctic Circle，in contrast, there is no habitation that a man can describe as home; the only plants are a handful of mosses and lichens; the only landlife simple one-celled creatures and wingless flies; no human child has ever been born there.

MACQUARIE ISLAND: from Chaos toConservation麦夸里岛:从混乱不堪到精心保护I am standing on Macquarie Island, in the South-west Pacific Ocean, halfway between Australia and Antarctica. Strong winds and stormy seas have helped sculpt its long, thin shape. The green grass and bare rock of its landscape contrast dramatically, giving it a wild and natural beauty. No visitor would think it surprising that the island is a UNESCO World Heritage Site.Nor would they fail to imagine how its native inhabitants including royal penguins, king penguins, and elephant seals existed in perfect harmony with their natural habitat forthousands of years. 我正站在麦夸里岛上,这里位于太平洋的西南部,澳大利亚和南极洲的中间。
强风和惊涛骇浪将海岛塑成现在狭长的形状。
绿草和光秃的岩石形成的景观反差巨大, 使海岛呈现出一种狂野和天然的美。
这座岛是联合国教科文组织确立的世界遗产, 游客们都认为其名副其实。
他们也不难想象出,数千年来,包括帝企鹅、王企鹅和象海豹在内的当地动物是如何与其自然栖息地完美地和谐共存的。
But the islands more recent history tells a different story. It a tragic story that began in 1810 when humans arrived on the island. In their ships they unknowingly brought rats and mice.These small animals quickly took over the island, eating the birds’ eggs and attacking baby birds. Cats were brought to the island to control the rats and mice. Unfortunately, the catssubsequently developed an appetite for the birds, too. 但是,这座岛近些年的遭遇则是截然不同的故事。

大学精读第二册课文第五单元
The V illain in the Atmosphere （大气层中的恶棍）The villain in the atmosphere is carbon dioxide.大气层中的恶棍乃是二氧化碳。
It does not seem to be a villain. It is not very poisonous and it is present in the atmosphere in so small a quantity — only 0.034 percent — that it does us no harm.二氧化碳看上去不像一个恶棍。
它毒性不大，在大气层中的含量极小——只占0.034％——不会对我们造成任何伤害。
What's more, that small quantity of carbon dioxide in the air is essential to life. Plants absorb carbon dioxide and convert it into their own tissue, which serve as the basic food supply for all of animal life (including human beings, of course). In the process they liberate oxygen, which is also necessary for all animal life.再者，空气中的那一点点二氧化碳对生命至关重要。
植物吸收二氧化碳并将其转化成它们自己的组织，充当所有动物（当然也包括人类）的基本食物供给。
在这一过程中，植物释放氧气，而氧气又是所有动物生命所不可缺少的。
close4RT But here is what this apparently harmless and certainly essential gas is doing to us:然而，这一看上去无害而且无疑又必不可少的气体却正在对我们产生影响。
