南极：Antarctica；北极：North Pole；Life on an Antarctica station is hard. It is like life on a space station. The sun shines for six months, and then it is night for six months. People usually have problems with sleeping and eating. They eat more because they are not busy. In an emergency, it is hard to get help. In 1999, an American doctor named Jerri Nielsen realized she was sick. She had cancer. It was winter, and airplanes could not land in Antarctica. She was the only doctor there. Dr. Nielsen had no choice. She had to stay and take care of herself with the medicine dropped to her from an airplane. Only after several months, when the sun shone again, was Dr. Nielsen able to return to the United States to get special medical help.来源新东方英语·中学版

北极和南极的纬度分别为北纬90度（或90°N），南纬90度（或90°S）。北极地区：北纬66度34分至北纬90度。南极地区：南纬60度至南纬90度。北极（英文：North Pole；法文：Arctique）。北极地区的气候终年寒冷。北冰洋是一片浩瀚的冰封海洋，周围是众多的岛屿以及北美洲和亚洲北部的沿海地区。北极是指地球自转轴的北端，也就是北纬90°的那一点。北极地区是指北极附近北纬66°34′北极圈以内的地区。南极：指南极点，即南纬90°。南极地区：指60°S-90°S以内的区域南地极：南地极位于南极洲内，并插有标记。但由于大陆漂移，在地球的历史上其实大多数时间南极洲都在距离南极很远的地方；而且，每隔一段时间，地理学家都要修正南极的位置。对上一次修正南极位置的时间，就在南极地区踏入2000年时。
