节约用水

　　There are many ways to save water. One is to reuse water. For example, when we wash hands, we'd better use basins so that we can reuse the water to clean toilet. Another way to save water is not to waste any drop of clean water. Don't forget to turn off the water pipe. One more way to save water is to save products that are made out of/in water and products that need water in their production.
