Water
As we know, water is
very important tohuman, we can’t live without water.There is water under the ground and in the air. In cold weather we see ice
and snow. They are water. In the sky, we can see the cloud. They are water,
too.
But where is the water from? The sun shines down on seas, rivers or lakes
and the water becomes vapour. Vapour cool
down and form clouds in the sky. Clouds havetoomuchvapour in it and can’t hold any more, it rains.The water goes back intoseas,
rivers or lakes. This is the watercycle
But some people don’t
care about it .They waste a lot of water in theirlife. Even worse, they
pour dirty water in to rivers.And the rivers flow to the sea. Much
water ispolluted.
If we don’t save water, the last drop of water will be a tear-drop
of us.

Why is the water very important to human?

Where is the vapour from?

Why is much water polluted?
