Water can be a liquid, a solid or a gas. When it is a solid, it can be as hard as stone. When it is a liquid, it can run through your fingers. When it is a gas, you may not see or feel it.
Water can change from a solid to a liquid or to a gas easily. This is why we always have fresh water. Now let us find out how it does. The heat of the sun turns liquid water into gas from the oceans, seas, rivers and lakes. The heat also turns liquid water into gas from the ground, the plants and the animals. Water in the gas rises and turns into clouds in the air.
When the clouds come near a mountain, they rise high. As the clouds rise, they get cooler. The higher they rise, the cooler they become. Then more and more water gas turn into water drops. In this way, the drops of water in the clouds get bigger and bigger. Then they fall to the earth as rain.

Have you ever been ill? When you are ill, you must be unhappy because your body becomes hot, and there are pains all over your body. You don’t want to work, and you stay in bed, feeling very sad.
What makes us ill? It is germs(细菌). Germs are everywhere. They are very small and you can’t find them with your eyes, but you can see them with a mi­croscope(显微镜). They are very very small and there could be hundreds of them on a very small thing.
Germs are always found in dirty water. When we look at dirty water under the microscope, we shall see them in it. So your father and mother will not let you drink dirty water.
