Sometimes the clouds are so low that they touch the trees and the ground, so low that they float(漂浮) above the water. We call that fog(雾). When the small drops of water in clouds or fog get very closed together, they make big drops. These big drops are so big that they can’t float in the air. They fall off. And that is rain. There is always water in the air. When the air is cold, snow falls instead of rain. Have you touched a piece of ice? It’s cold and hard. If it is very thin, you can see through it, just as you can see through glass. If it is very thick, it is very strong enough to skate on or to build a house on. But do you know what ice is? It is water.
