One reason why the Santa Fe Opera is so good is that it attracts many excellent young singers. They all hope to sing in famous opera houses like Metropolitan in New York someday, and they work hard to become well-known during the summer．The musicians and directors are experts who come from the best orchestras (管弦樂隊) and operas in the country during their vacations．They enjoy working there because they like to live in Santa Fe，which is near both the mountains and the desert．It is very beautiful there in the summer.
The state government of New Mexico advertises the Santa Fe Opera in newspapers all over the country, and a great many tourists come to New Mexico because of the opera.

The opera house in Santa Fe，New Mexico is one of the most beautiful ones in the United States. It is small and open，with one roof over the stage where singers perform and another roof over part of the audience．This opera house in the mountain is one of the best in the country, which may seem surprising because performances are only given during seven weeks in the summer，and because Santa Fe is a very small city．
