听力原文: There are many famous museums throughout the world where people can enjoy art. Washington D.C.has the National Gallery of Art; Paris has the LouvrE.Florida International University in Miami also displays art for people to seE.And it does so without a building, or even a wall for its drawings and paintings.Florida International University has opened what it says the first computer art museum in the United States. You don't have to visit the university to see the art. You just need a computer linked to a telephonE.You call the telephone number of a university computer and connect your own computer to it. All of the art is stored in the school computer. It is computer art, created electronically by artists on their own computers. In only a few minutes, your computer can receive and copy all the pictures and drawings.Robert Shostak is director of the new computer museum. He says he started the museum because computer artists had no place to show their work.A computer artist could only record his pictures electronically and send the records, or discs, to others to see on their computers. He could also put his pictures on paper. But to print good pictures on paper, the computer artist needed an expensive laser printer.Robert Shostak says the electronic museum is mostly for art or computer students at schools and universities. Most of the pictures in the museum are made by students. Mister Shostak says the Florida International University museum will make computer art more fun for computer artists because more people can see it. He says artists enjoy their work much more if they can have an audiencE.And the great number of home computers in America could mean a huge audience for the electronic museum.(33)A.In Paris.B.In London.C.In Miami.D.In Washington D.C.
