    Benedict Alien was born in England in 1960. His dad was a pilot，and Benedict dreamed of traveling around the world like his dad. His dream came true. Benedict became an explorer. But he doesn' t travel the world in a plane. He finds a place he wants to explore，and then he lives with the local(本地的)people. He learns important skills, from them，and then uses those skills to explore the place he's visiting. He doesn't use modern things like cellphones(移动电话)，and he likes to travel alone.

    Benedict's explorations are often dangerous，but he likes them. One of his favorite explorations was in 2001. He wanted to be the first person to travel alone across the ice from Siberia to Alaska. So he went to Siberia and lived with the Chukchi people. He learned how to live like the Chukchi people and drive a dog team. He traveled 622 miles with only a dog team. The weather was really bad. There was a lot of snow, wind and ice，so the journey was very difficult. Benedict almost lost the dog team，and he almost died，so he ended his journey early. It was scary, but he learned a lot.
