听力原文： Hotels today are quite different from those of the past．People who stay in them are generally traveling for business，or they are touring or on vacation．So hotels are designed mainly to meet the needs of one of these two groups of people．Hotels designed for business people are known as commercial，or transient hotels．Hotels for people on vacation are called vacation， or resort hotels．

Transient hotels are usually located in the business section of a town，while resort hotels may be at the seashore，on a mountain lake，or in the desert．

In addition to these two main types，there is a third type of hotel，called a residential hotel．This is designed to meet the needs of people who want to live in a hotel．

Inns and hotels are located in nearly every population center in the world．In the United States alone there are about thirty thousand．Some hotels have as few as ten rooms，others have several hundred．Among the largest hotels in the world today ale the Conrad Hilton in Chicago，Illinois，and the Russia in Moscow，each with about three thousand rooms．
