Many people go to Utah because they love hiking in Bryce Canyon National Park. They enjoy 1.(岩石) climbing, camping and so on. However, some people go to Utah for a very 2.(不同的) experience.

The Boulder Outdoor Survival(生存) School(BOSS) in Utah is the world’s oldest survival school. It teaches people how stay alive without tents, or even backpacks. In Bryce Canyon, the days are very 3.(热的) and the nights are very cold. Not everyone wants to go and experience life without modern 4.(发明) like smart phones and e-books. Students at BOSS quickly learn that it is important to work hard and 5.(尝试) new things if they want to complete the training.

In survival camps at BOSS students don't just practise camping, hiking or6.(骑) horses. They go into the wild for days or weeks. They learn how to find 7. (新鲜的)water for drinking. They also learn how to make a fire, use a 8.(小刀) and find food to eat.  Nature can often give them 9. (每件事) they need so survive.

After these people go back to the real world, they may never use these skills again. Even if they don’t, at 10.(至少) they will always know that they can live without computers, electricity, and smart phones—even if it is only for a few days!
