Who hasn’t enjoyed eating peanuts? Did you know that although peanuts look like nuts and taste like nuts, they aren’t nuts at all? They belong to the pea family, so they are called peanuts. The peanut grows flowers above ground, but its “fruit” grows underground. It grows in more countries than most other “nuts”.

The peanut is a native South American plant. Scientists believe that it grew wild in Brazil long ago. They think that for several thousand years the early peoples of South America made it a part of                                                             

their diet. These peoples were nomads who moved on when a natural food could no longer be found in one area. Along the way they probably let fall some peanuts, which got into the ground

In 2000, at the age of 56, Jeff was going to take a difficult and dangerous journey（旅程）in the Arctic（北极地区）. He was planning to walk to the North Pole all by himself, pulling his food, tent and other things behind him in two sledges（雪橇）. Because the Arctic is covered with ice and water, he would sometimes have to sit on his sledges and use them like a boat!

Before he started his journey, to make himself stronger, Jeff spent 2 years practicing running and took part in many boat races. He had also traveled in the Arctic for 28 years. All of this was good for him. But there was still trouble.

Jeff was seven days into his journey in the Artic. It was dark and terribly cold（－35℃）. In face of this terribly low temperature, he had made good progress across the ice. Suddenly, the ice broke and one of his sledges fell into the sea. Jeff needed to get it back, so he had to put his hand into the ice ? covered water.

Once he had got the sledge back, Jeff put up his tent, lit a fire and tried to warm up his cold hand. It was no help ? his hand was seriously hurt as it had been in the cold for so long. He radioed for help, and an airplane was sent to save him. Finally, he arrived at a hospital in Canada. The doctors there said he hurt his left hand in the icy water. They saved his hand and advised him not to travel to the North Pole alone any more.

But Jeff was an explorer and nobody could change his mind. It would be yet another long and difficult battle for Jeff soon.
