Salt has always been important to people. In the past, it was as valuable as gold. Over the years, people discovered different ways to get salt. Some early people got salt from rocks. In other places, people got salt from the sea. They took sea water and put it in the sun. After a long time, the water dried up（耗尽）. Then people could get salt.

Today, people still get salt from the sea. But most salt comes from salt mines（矿）and salt wells（井）. How do people get salt from salt mines? They dig deep into the ground for it. To get salt from salt wells, people put two pipes（管子）into the ground. Water is sent down through one of the pipes. And the water is mixed with the salt in salt wells. It makes salt water.
