    There are many new ways of shopping in the world. Do you know all of them?

    One popular way is catalog shopping(目录购物). There are catalogs for almost anything you need—like clothes, furniture, cooking and so on. People also order about 40% of their music from music club catalogs.

    Another way of shopping is shopping by TV. It began in 1986. About 5% to 8% of the Americans now shop by television. People say that it is easier than shopping in a shop. TV shopping is late at night, so people can "go shopping" happily after a day's work.

    Computer shopping or "shopping online" is interesting to more and more people. Is computer shopping the way of tomorrow? Already, people can use their computers to order many different things, such as computers, flowers, food and T-shirts. Soon people may be able to shop for anything, anytime and anywhere in the world.
