谁有一件难忘的事?

Maybe the last water is our tears
　　As we know water is made up of our life,we could not leave without water.No water will no we.
　　Water is needed more and more,because our industry and agriculture produce developed fast.Somewhere water are scare,and some rivers are no water in them.But just little water is polluted,more waste water did not handled and discharge into river.
　　Around us there are a lot of students don't pay attention to save water,for example:after they washing their face and rinsing the mouth,they don't turn off the water tap .Let the water flowing day and night.What a pity!
　　Expect the tings I just mention,there are more and more in our life.So now I hope our students take care of wate.And the same time we need do things to prevent water pollute as we can do .That's what I want to say.Why not do it right now,come on .
