Water is very important to us. If there is no water, we will die. We can eat nothing for few days, but we must drink water every day. Besides, if there is no water, the plants will not grow, and the animals will not live. Therefore, there will no food for us. But the water has been severely polluted nowadays. Much water is not suitable for drinking. For our human beings and our planet, we must protect water. Without it, there would be no life any longer in earth.

　　水对我们来说是很重要的。如果没有水，我们会死。我们可以几天不吃东西，但是我们每天都必须喝水。此外，如果没有水，植物就不能生长，动物也活不下去。因此，我们也就没有了食物。但是现在水资源却被严重污染，很多水都已经不适合饮用。为了我们和我们的星球，我们一定要保护水资源。没有水，地球上也就不会再有生命的存在。
