Vision-phones(可视电话)
Radio，telephone and television are widely used in the world.

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 type of telephone called vision-phone. With it two people who are talking can see each other．
Vision-phones can be of great use when you have something to show the person whom you are calling，It may also have other uses in the future．Some day you may be able to call up a library and ask to read a book right over your vision-phone. You may be able to do some shopping through it, too. Perhaps in the near future, vision-phones will e into wide use in our everyday life.
