How much do you know about the North Pole(北极) and the South Pole? They are both places 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. Temperatures seldom go above 32°F, at which water turns into ice. Most of the time, it stays below zero. In winter temperatures are usually as low as-30°F.
Although conditions were very poor, people tried for many centuries to reach the North Pole. Over 100 years ago, two men, Robert Peary and Mathew Henson, were able to get to this environment full of troubles and difficulties. They reached the North Pole on March 8th, 1909. It was really a hard trip for them.
There are few things more dangerous than crossing the Arctic(北极圈) on foot. People who stayed there may face many problems: very cold temperatures, sudden storms, and even hunger. Most of the area is uninhabited, few people can live in such a difficult place.
People might think 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) called "leads". Anyone who falls into a lead can be frozen to death in a few minutes.

This is a tale of two friends, 53-year-old Jia Haixia and Jia Wenqi. One is blind, the other has no arms. On their own, the two are "disabled". But together, they are a powerful team that has changed part of their village in North China's Hebei Province into a rich, green forest.
Their story began in 2000, when Haixia, who was already blind in his right eye, lost his left one after an illness. Wenqi lost his arms in an accident when he was just three. Neither could find a job, so the two decided to team up. They rented some poor land and began to plant trees. In return, the local officials paid them a small fee. Haixia and Wenqi never imagined that they would end up creating an environmental paradise. Their forest now has over 10,000 trees, hundreds of birds and many other wild animals. In addition, it saves the village from river flooding during the rainy season.
When the friends work together, they focus on their strengths not their disabilities. Their day begins at 7 a.m. when the sightless Haixia carries Wenqi across the river to get to their worksite. Since they cannot afford to buy young trees to plant, the two use branches from existing trees. Haixia climbs to the tree-top and with Wenqi's direction, selects the perfect branch. He then digs a hole and carefully plants it. Finally Wenqi waters the area. Though hard-working, the men don't make much money. But as Wenqi puts it, "We stand on our own feet, so the fruits of our work taste sweeter."
Neither Haixia nor Wenqi cares about money. Together, they already have everything they need- a perfect pair of eyes, two strong hands, and the best friendship in the world!
