北极与南极
Arctic vs Antarctic
知道北极（北冰洋）和南极（南极洲）非常不同——北极是被陆地包围的冰冻海洋，有人类和北极熊生活在那里；南极则是被海洋包围的巨大冰封大陆，有企鹅生活，但没有人类长期居住。
Know that the Arctic (North Pole) and Antarctic (South Pole) are very different — the Arctic is a frozen ocean surrounded by land where people and polar bears live, while the Antarctic is a huge ice-covered continent surrounded by ocean where penguins live but no people live permanently
学习证据 / Evidence
- 说出北极是被陆地包围的冰冻海洋，而南极是被海洋包围的冰封大陆。
- 解释北极熊生活在北极，企鹅生活在南极，而不是反过来。
- 知道北极有人生活（比如因纽特人），但南极没有人长期居住。
- State that the Arctic is a frozen ocean surrounded by land, while the Antarctic is a continent covered in ice surrounded by ocean
- Explain that polar bears live in the Arctic and penguins live in the Antarctic, not the other way around
- Know that people (like the Inuit) live in the Arctic but nobody lives permanently in Antarctica
