Helen Thayer, one of the greatest explorers of the 20th century, loves challenges. She says，“I like to see what's on the other side of the hill.” She has gone almost everywhere to do that.

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 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 adventures，but also for education.Before her Arctic journey，she started a website called Adventure Classroom.On the site，she shared her adventures in order to inspire students.She explained，“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 the age of nine.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 travelled on foot from west to east through the Gobi Desert in Mongolia.They hope to travel in mainland China into Sichuan and Tibet to study pandas.

Helen plans to continue taking trips.She'll use her explorations，writing，photography and environmental works to create programs for her Adventure Classroom website. She wants to inspire her students to never stop facing challenges.
