In 1988，at the age of 50，she became the first woman to travel alone to the North Pole.She pulled her own sled(雪橇) piled with 160 pounds of supplies，and during her trip no one brought her fresh supplies.Accompanied(陪伴) only by her dog Charlie，she survived cold weather and meetings with polar bears.In fact，Charlie saved her life when one of them attacked her.Near the end of her trip，a forceful wind blew away the majority of her supplies.The last week of the trip，she survived on a handful of nuts and a little water each day.

　　Helen goes to challenging places not only for adventure，but also for education.Before her Arctic journey，she started a website called Adventure Classroom.On the site，she shares her adventures in order to motivate(激发) students.She explains，“although kids often see the world in a negative way，without hope for their future，we work to inspire them to set goals，plan for success and never give up...”

　　Helen grew up in New Zealand.Her parents were athletes and mountain climbers.Following her parents’ example，she climbed her first mountain at 9.Later，she climbed the highest mountains in North and South America，the former USSR and New Zealand.

　　In 1996，she took on another challenge—the Sahara Desert.She and her husband，Bill，walked 2,400 miles across it！In 2001，she and Bill traveled on foot from west to east through the Gobi Desert in Mongolia.They hope to travel in Chinese mainland into Sichuan and Tibet to study pandas this year.
