Jerry is a world-famous mountain climber. He has climbed many high mountains in the world. Starting in 2015, he and his friends spent two years on an adventure（探险）in South America, covering 7,800 miles. He was even named Adventure of the Year by a famous geography magazine in 2018.

Although Jerry had achieved great success, he didn’t feelfulfilled. He asked himself, “Is it enough to climb the highest mountains? Am I doing something helpful? How can I turn my adventures into something that can help the world?”

Jerry learned that scientists need plants, rocks and water samples（样本）from the places far away to do research. But scientists can’t get there themselves as such places are hard to reach——only the bravest adventurers can make it. Jerry thought himself could do something to help. He then came up with an idea. He set up a team of top adventures to collect samples for scientists. By studying the samples, scientists could know more about the earth and find ways to protect it.

Recently Jerry and his adventurer friends have discovered a special plant life of Mountain Qomolangma. The samples they brought back have helped scientists how plants live in extreme（极端的）conditions.

For Jerry, this kind of adventure is most satisfying. “Such adventures had made us see life in a different way. Now, being the best climber isn’t important for me, what matters is doing something helpful while climbing the mountains. There is still much more we can do.” Jerry said to a newspaper.
