Water is the most valuable resource on the earth. Water is the necessity of our life and we must drink it everyday.Now, many people can not drink clear water, because many of them are badly polluted. So, in order to save water, the first thing we should do is reduce water pollution. In addition, we should develop good habits to save water. For example, turn off the tap after we use. Or we should recycle the water to make it full use. In one word, water is scarce for all of us and we should try our best to save it.

水是地球上最宝贵的资源。水是生活的必需品，我们每天都需要喝水。现在，很多人都喝不到干净的水，因为很多水都被严重污染了。因此，为了节约用水，我们首先要做的就是减少水污染。另外，我们应该养成节约用水的好习惯。比如，用完水的时候关掉水龙头。或者我们应该循环用水以达到充分利用。总之，水是对我们大家都是稀缺的，我们应该尽最大努力保护它。
