16.London has a magazine.But you can receive it on TV because it is not printed on paper. If you want to read this magazine,you have to get a decoder(解碼器).Each page of it is numbered,so you only have to dial the number to choose what you want to read about.You can choose everything you want,from cooking to the latest news. If you want to read the news,the first thing you have to do is to turn to the index(索引) page which has an easy to remember page number,100.Then you choose what you want to read.The news is on pages 101 to 109,so you push out the numbers and you can watch the news written across your screen.Perhaps you want to go out in the afternoon,so you press 181,and you can see a brightly colored weather map on the screen.But should you drive or take the train?To answer that question you only have to press 189 for the traffic report. It is very simple to use.But the best thing about the service is that it is being updated(更新;使……跟上時代) all the time.The whole pages of the magazine can be replaced in minutes. London already has three services.One,transmitted by TV,is called ORSCLE while the other two,on BBC,are called CEEFAX because they let you see facts.Though CEEFAX and ORACLE have been in use for some time,they have not been publicized.BBC engineers don't think that their idea will ever replace books and newspapers because they can be taken with you everywhere.But many people would agree that this is a breakthrough as great as the invention of printing,which could change not just our reading habits but our whole way of life.
