Act now to save water 　
　　Water is very important to us,water can bring human being back to life,so we can't live a no water's life. 　
　　Nowadays,someone even wastes water in usual.In school canteen,some students were not closed the tap while they had washed hands,parts of the students were having a bad habit of just throwing the bottled water without drinking over.In school dormitory,someone was used to spending a long time taking shower. 　
　　What should we do about the water shortage?I think,first,the people should be made aware of the real situation about the water.We have to protect the existing water resources and develop new ones.So save water,take actions from now on.
