If you have no special plans for your holidays, why not spend your time helping others?
Don't listen to people who say the young people today often think only of themselves．It's not true at all．More and more people in the USA volunteer to spend their school holidays working for others．And they don't do it for money．Here are some of their stories．
Alice Hamilton, 17
I'm going to help the Forest Centre build new hiking paths in the mountains．It's going to be terrific-I'll spend the whole summer living in the tent and breathing the clean mountain air．I'm going to sleep under the stars．It'll be a nice sport, and I'll be able to do something good at the same time．
Jason Moore, 18
This summer, I'm going to volunteer with Special House Program．They build good, low-cost houses and sell them to families that are not very rich．They'll teach me what to do, so I'll help people and also have a chance to learn how to build houses．
Trish Anderson, 16
I'm going to teach kids who have trouble reading．I'll work for a program called Reading For Life．Every d ay, I'm going to help kids choose and read books that they like．I want to be a teacher and I love children and reading, so this is going to be a great experience for me．

Do you think stones can move by themselves? There are some famous moving stones in Death Valley, the US．Many of the stones are small but a few of them are very big．Some of the big stones are as big as a man．The biggest stone weighs about 350 kg．
The stones only move at night．Nobody has ever seen them moving, but now scientists know the answer to the question．The answer is the wind．When the wind comes from the west, the stones move to the east．When the wind is from the north, they always move to the south．But how can the wind move a very heavy stone?
Death Valley is one of the hottest places in the world, but it can be very cold at night．Sometimes, there are even bad storms (风暴) at night．Rain falls, and the wind is strong and cold．The water on the ground turns into ice easily．Then the strong wind can move the stones along the flat (平坦的)ground．In the morning, the sun comes up and dries the ground．So people can find them move from one place to another in the daytime．
