      Water is all around us. Water is in the ocean. Water is in the lakes and rivers. Water is in the air. There is

more water than land on the earth. All things must have water to live. The plants must have it. The animals must

have it. We must have it, too. We cannot live without drinking water. Sometimes, we do not have all the water

that we need. The land will dry up without water. Sometimes, there can be too much water in the land. If it rains

very, very hard, the rain water will run down the hills. It takes some of the land with it when it runs down the

hills. It is called erosion when the water takes the land away. 

      Water on the earth will never be used up. It goes from the ocean to the air to make clouds. Then, it falls

from the clouds down to the land. It runs off the land and out to the ocean again. The clouds make rain. The rain

falls onto the land. Some of it goes into the ground. Some of it washes down and goes back into the ocean.

Some water that falls down from the clouds is not rain. Some of it washes down and goes back into the ocean.

Some water that falls down from the clouds is not rain. Some of this water is snow. The snow is made of

water. Some water that is not rain or snow falls down from the clouds. Some of this water is sleet (雨夹雪).

The sleet is made of little pieces of ice. Some water that is not rain or snow or sleet falls down from the clouds.

Some of this water is hail (冰雹). The hail is made of ice balls!
