比较北极与南极

详细比较北极和南极：北极是被漂浮海冰覆盖的海洋，周围有陆地（加拿大、俄罗斯、格陵兰、斯堪的纳维亚）；南极洲是比欧洲还大的大陆，被厚达4千米的冰层覆盖；北极熊、北极狐和海象只生活在北极，而企鹅、豹海豹和信天翁只生活在南极。

Compare the Arctic and Antarctic in detail — the Arctic is an ocean covered by floating sea ice with surrounding land masses (Canada, Russia, Greenland, Scandinavia), while Antarctica is a continent larger than Europe buried under ice up to 4 km thick; polar bears, Arctic foxes, and walruses live only in the Arctic while penguins, leopard seals, and albatrosses are found only in the Antarctic

学习证据 / Evidence

• 说明北极是被陆地包围的冰冻海洋（至少说出两个周边国家），而南极洲是被厚达4千米的冰盖覆盖的大陆。
• 能正确说出至少三种动物生活在北极、至少三种动物生活在南极。
• 至少说出两个人类活动方面的不同：北极有原住民，而南极只有科考站。

• State that the Arctic is a frozen ocean surrounded by land (name at least two bordering countries), while Antarctica is a continent covered by ice sheet up to 4 km thick
• Correctly assign at least three animals to the Arctic and three to the Antarctic
• Name at least two differences in human presence: indigenous peoples in the Arctic vs research stations only in Antarctica
