应该是Water【水】吧~water Everything can't live without wather.So it's important for us to protect and save the water.We shouldn't throw litter into the lakes and rivers.We should plant more trees and grass because they can prevent the earth from running away.We should turn off the tap in time and reuse the water.We'd better wash our clothes by hand instead of using washing machine.If everyone makes a contrubition to protect the water,the world will be more beautiful.好了.我打了好久啊~
