Water is very important for living things. Without water there can be no life on the earth. All plants and animals need water. Man also needs water. We need water to drink, to cook food and to clean ourselves. Water is needed in farms, factories, offices, schools and families.

　　Water is found in seas, rivers and lakes. It can be found everywhere in the world, and it can also be found in the air. We cannot see or feel the water when it is part of air. Clouds are also made of water. Thay are little drops of water. When water freezes, it is ice. So ice is also water.

　　Air is all around us. It is around us as we walk and play. From the moment we are born, we are surrounded （围绕） by air. When we sit down, it is around us. When we go to bed, air is also around us. Where we are on the earth, we are surrounded by air, and we live in air.

　　All living things need air. Living things cannot live without air. We can go without food or water for a fewdays, but we cannot live for more than a few minutes without air. We breathe（呼吸）in air. When we are working or running, we need more air. So we breathe faster than usual. When we are asleep, we need less air.
