　　　　　　　 Visionphone

　　 Radio, telephone and television are widely used in the world. When you turn on the radio, you can listen. But when you use telephone, not only can you listen to others but you can also talk with them; however, you can't see anything at

all. Now television is much better than both of them. People can watch TV and listen to it, but they can't take part in what they see.

　　　 Today, some people are using a new type of telephone called visionphone. With the visionphone, two people who are talking can see each other.

　　　 Visionphones can be very useful when you have something to show the person whom you are calling. It may also have other uses in the future. Someday you may be able to call up a library and ask to read a book right over your visionphone. You may be able to do the shopping through it, too.

　　　 Suppose you read about something in the newspaper that you want to buy, you will go to your visionphone and call the shop. The shop assistant will show you the thing that you're interested in. You'll be able to shop all over the town and never leave your home.

Perhaps in the near future, visionphones will come into wide use in our everyday life.
