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!
The world is not only hungry, but it is also thirsty for water. This may seem strange to you, since nearly 70% of the earth’s surface is covered with water. But about 97% of that is sea water or salt water. Man can only drink and use the other 3% fresh water from rivers, lakes，underground and other sources. And we can not even use all of that. Even worse, some of it has been made dirty.
However, as things stand today, this fresh water is still enough for us. But our need for water is becoming larger and larger quickly, almost day by day. We should take steps to do with this problem now and in this way we can get away from a serious world-wide water shortage(缺少)later on.
We all have to learn how to stop wasting ourvaluablewater. One of the first steps is to develop ways of reusing it. Today in most large cities, water is used only once and then sent out into a sewer system (下水道). From there it returns to sea or runs into underground places.
But even if every large city reused its water, we still would not have enough. All we’d have to do to make use of sea water in the world is to remove the salt. If we take these steps we’ll be in no danger of drying up.
