We cannot live without it. There is a lot of water on the Earth, but we cannot use most of it. About 97. 5% of the Earth39。s water is salty. Most of the fresh water is snow and ice near the North and South Poles（極）. We can only use less than one per cent of the water on the Earth. We use water from both lakes and rivers. Some of the water evaporates and then bees rain. Of course we use rain water for farms and other things. We use this water again and again. Sometimes the Earth39。s water is in the wrong place. There is a lot of rain in the tropics（熱帶地區(qū)），but it is difficult to have farms in the tropics. Most of the land there is not very rich. Some desert land is rich, but there is only a little water in the desert. Water is a problem for many people in the world. （1）About of the Earth39。s water is fresh.

There is some salt in all water. Water on the land runs into lakes and rivers. These rivers run into the seas and oceans. They carry a little salt with them. Some of the ocean water moves into the air and clouds. It evaporates. Salt cannot evaporate. It stays in the oceans. The water in the oceans has more salt than river water. There is about 3. 5% salt in the ocean water. Some seas have more salt than others. Some of the water leaves the lakes. It evaporates, but the salt cannot. These lakes are very salty. There are two famous lakes like this. They are the Dead Sea in the Middle East and the Great Salt Lake in Utah（猶他州）in the United States. They are much saltier than the Atlantic Ocean（大西洋）and the Pacific Ocean（太平洋）. （1）Where may some water in the oceans go?
