Professional adventurer Mike Horn never met a challenge he didn’t welcome. In fact according to Horn, “The impossible exists only until we find a way to make it possible.” As a child in Johannesburg, South Africa, Horn excelled at sports and loved adventure. But it wasn’t until he moved to Switzerland in 1990 that his life of adventure really began. Horn had always loved sports and taking risks, and he was known for his crazy feats. He traveled in the South American Andes Mountains in the early 90s and then in 1997 crossed the entire continent on foot. He finished by floating 7,000 km down the Amazon River! In 1999, H      orn began a solo trip around the world following the equator,without the use of any motor-powered transportation. When he finished successfully 17 months later, he became the first person to accomplish the feat. Horn’biggest challenge to date came in 2006. He and a fellow adventurer walked from Russia to the North Pole in the sunless winter. Traveling through the winter darkness, he encountered polar bears and many other dangers. In 2008, Horn began another unique adventure –one that will take four years to complete. Instead of trying to achieve more personal goals, Horn is now dedicated to sharing his knowledge and experience with others. He calls his latest expedition the “Pangaea Expedition.”with “Pangaea” standing for “a Pan Global Adventure for Environmental Action.”By the end of this expedition, Horn will have traveled 100,000 km and crossed all of the continents and oceans. But this time he won’t be going alone: He’s choosing young people from around the world, aged 13 to 20, to accompany him. Twelve young men at a time will participate in one of 12 different projects, ranging from studying glaciers to treating water sources. The journey will take place onboard Horn’s 35-meter saiboat , the Pangaea which will become a floating science class . Along with a team of scientists, Horn plans to teach the young explorers about protecting and preserving the earth. In perhaps his most important expedition, Horn will pass down his passion for Earth’s wonders to the next generation. 64.Which of the following is NOT ture? A.
