     There are many unusual hotels around the world. In Greenland, there is a hotel made out of ice, open

 between December and April every year. In Turkey, there is a cave hotel with a television, furniture, and

 a bathroom in each room. And in Bolivia (玻利维亚-南美洲西部国家), there is the Salt Palace Hotel.

     Thousands of years ago, the area around the Salt Palace Hotel was a large lake. But over time, all the

  water disappeared. Today, the area has only two small lakes and two salt deserts.

     Uyuni salt desert

     The larger of the two deserts, the Uyuni, is 12,000 square kilometres. During the day, the desert is

 bright white because of the salt. There are no roads across the Uyuni desert, so local people must show

 guests the way to the hotel.

     In the early 1990s, a man named Juan Quesada built the hotel. He cut big blocks of salt from the desert

  and used the blocks to build it. Everything in the hotel is made out of salt: the walls, the roof (屋顶), the

  tables, the chairs, the beds, and the hotel's bar.

     The sun heats (使变热) the walls and roof during the day. At night the desert is very cold, but the

 rooms stay warm. The hotel has twelve rooms. A single room costs $40 a night, and a double room costs

  $60.

     A sign on the hotel's wall tells guests, " Please don't lick (舔) the walls."

     (注: Uyuni is a town in the south of Bolivia.)
