At one time or another we have all stopped to think about weather. Some days the weather is good. Some days the weather is bad. Still, there are days when the weather seems to change from hour to hour. A day that starts out fine might not stay that way. Sometimes a day that seems bad turns out better than you thought it would. There are ways of understanding the weather. One way is to study the clouds.
No two clouds are ever alike. But it is still possible to group clouds and to give them names. We can recognize the different kinds of clouds and watch them for signs of changing weather.
As a rule, the higher the clouds, the better the weather. And the lower the clouds, the worse the weather is likely to be. To predict the weather, there are three things about clouds you should look for: movement. color, and change.
Clouds can tell you if storm is on the way. For example, small feathery cirrus clouds(卷云) can become thick and move lower. This means rain is on the way. If there is a sudden, cool breeze（微风）and a dark thunder(雷声) clouds appears, then a storm is about to break out.

Mike Myers is a teacher at Chauncey Rose High School in Terre Haute, Indiana. Last year, he taught his students about the world’s rain forests. They learned that rain forests are important because the plants and animals of the rain forest give us food, wood, and medicine.
Destruction of the world’s rain forests is a serious problem. Unluckily, rain forests are disappearing at a rate of 80 acres per minute! As part of a class project, Myers’ students bought three acres of rain forest in Central America. They paid $25 per acre. The students hope that the land they bought will be protected and not destroyed. The students became so interested in rain forests that they decided to get a closer look at a real rain forest.
So last June, Myers and four of his students took a boat ride down a river. They saw alligators and crocodiles. In the middle of the week, a guide took Myers and his students into the rain forest. “The monkeys were not happy that we were in their forest. They broke small branches off the trees and threw them at us,” one of the students said, “It was a great learning experience for all of us,” said Myers.
Each student chose something specific about Costa Rica to study involving the plants, animals, food, and culture. During the last few days the group had time to do fun activities. They went whitewater rafting and horseback riding, and visited Costa Rica’s active volcano.
Myers hopes to make the trip every year with a different group of kids.
