Water

Can we live without water?No,nothing would exist without water.Everyone knows this,but not all of us know the important① of saving water.For example,some people use the running water to wash cars or buses.Some don't turn off the tap at once after washing.Some even wash the streets or roads with running water.They know water is very important for humans,and② they don't understand that the more water is.And our country is short of water.
