What does it mean
It means that we should save water.
If we don’t save water , the last drop of water will be our tear.
China’s water resources ([r ’s s]资源） seems a little rich, but most of the water is sea water, and sea water is salty, is not directly for drinking. In fact, freshwater resources are very small in China. We need more water in many areas ,especially
in the west China, so we mustn’t waste water, but try our best to save water. And our government has made laws
(法律）to protect our water resource.
