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
