Water is the most important in our lives. Not Many people understand this but it’s quite true. The human body can go without food for a long time. We’ve got many examples for this. Yet two or three dayswithout water can usually make people die. Man can’t live without water.

Many people don’t understand how much water the human body needs to work well, and many people, especially young people, do not drink enough water, even in very hot weather. About two thirds of our body is water. When we do sports, some of the water will get away from our body. If we don’t drink some water, our body won’t have enough water. And if we don’t have enough water, we’ll feel tired and many of us will get ill. So you know how important water is to us.

But at present we face water crisis(危机). Water is becoming less and less. So， we should protect water resources(资源) and try our best to save water in our daily life. Here are some tips for saving water:

1. Turn off the tap(水龙头) in lime.

2. Take shorter showers.

3. Don’t let water run while washing your face and reuse the water after we finish washing.

4. Encourage your friends and neighbors to join in the action of saving water.
