请不要浪费生命之源---水

最近，我发现有的小朋友下课用水龙头喷水玩，我感觉这样非常不对。

Recently, I found that some children play with tap water after class. I feel this is very wrong.

水是生命之源，所有生命都源自于水。比如说恐龙，它们的祖先就是在水中生活了几万年之后，才摆脱了水的束缚，爬上了陆地；再比如说我们人类，身体的百分之八十都是水。人如果没有了食物，可以存活十五天左右，但是如果没有了水，甚至连五天都活不下去。想想看，这样下去，浪费的水都能让一个生活在严重缺水的地方的人活上十几年，甚至几十年。有时候这些水可能就是一条人命呐！

Water is the source of life. All life comes from water. For example, dinosaurs, their ancestors lived in the water for tens of thousands of years before they got rid of the shackles of water and climbed onto the land; for example, we humans, 80% of our bodies are water. People can live for about 15 days without food, but they can't even live for five days without water. Think about it. In this way, the wasted water can make a person living in a place with serious water shortage live for more than ten years or even decades. Sometimes the water can be a human life!
