Water is the biggest problem in our Earth. We can only use and drink liquid water(液态水).But we can only drink fresh water in the liquid water. There are lots of water on South and on North. But there are solid water(固态水)that we called them iceberg(冰山).But the most water in our life is in the air.They are the gaseous water(气态水). So we must protect our water.If we still wasting water, the lastest water will be our tear.
