阅读理解。 Can you really travel around the world for free? Li Jun, a 17-year-old girl from Shenzhen Foreign Language School, still can't believe her 10-day free training (训练) camp in the Alps in Switzerland last month was true! But how did she achieve this once-in-a-lifetime opportunity? Last October, a piece of short world news in a newspaper—'Have a chance to see the world, for free', caught her eyes. When she asked her friends if the story was real, they laughed at her, for they thought she was day-dreaming. However, Li decided to apply (申请) online the following weekend. 'Opportunity is everywhere. I'd like to keep my eyes open and catch the chance.' she told herself. What happened next was tests on health, hobbies and awareness (意识) of environmental protection. She passed all of them very easily. On December 14, Li Jun surprised her friends with an invitation letter from the program, the Pangaea Young Explorer Selection Camp set up by South African explorer Mike Horn. On January 11, Li left for Switzerland, with several newly bought ski-suits in her suitcase. Over the next week, she and 15 other teenagers from around the world took part in exciting training and lessons. They took day-trips up the Alps to an altitude (纬度) of 3,200 meters, went sledging (滑雪橇) at night using modern equipment. They were also encouraged to complete difficult journeys up mountains, down hills, and through forests. Because of her performance during the training, Li was chosen as one of the eight young explorers to join Mike Horn in the South Island of New Zealand in May.
