People often think of the North Pole (北极) and the South Pole as similar frozen wastelands. They areplaces with very cold temperatures and few people live there. However, the North and South Poles are not much alike as people may imagine.
The North Pole has no land, only thick ice. Temperaturesgo above 32°F, at which water turns into ice. Most of the time, it stayszero. In winter temperatures are usually as low as -30°F.
conditions were very poor, people tried for many centuries to reach the North Pole. About 100 years ago, two men, Robert Peary and Mathew Henson, were able to get to this environment full of troubles and. They reached the North Pole on March 8th, 1909. It was really atrip for them.
There are few things more dangerouscrossing the Arctic (北极圈) on foot. People who stayed there maymany problems: very cold temperatures, sudden storms, and even hunger. Few people can live in such a difficult place.
Peoplethink that with such low temperatures for most of the year, the ice would be thick and hard. However, this is not true in the Arctic. The movement of the ocean water under the ice may often cause many different changes on the surface. Sometimes the ice breaks into two opening lanes of water (水道)"leads". Anyone who falls into a lead can be frozen to death in a few minutes.
