Water is very important to us,we can't live without water.Water pollution is a serious problem,it causes our drinking water becomes less .I think we should protect the water and reuse them,such as don't pour the waste water into the river,remember not to spit into the river and don't throw rubbish into the river and so on.We shoule save water . If we do these well,the water will be cleaner.If we don't save water,the last drop of water will be our tear.I really hope the government can do something useful to protect the water.

水对我们很重要。没有了水，我们就不能生活。水污染是一个很严重的问题，导致我们的饮用水变得越来越少。我认为我们应该保护水资源和重复使用水，例如：不要把污水排入河里，不要往水里吐痰，不要向河里扔垃圾等。我们还要节约用水，如果我们能作好以上几点，水就会变得越来越干净。如果我们不节约用水，那么最后一滴水就会是我们的眼泪。我真心希望政府能付出实际行动来保护水。
