【正确答案】[范文]
   Faced with countless media from the information age, quite a few people claim that books should be the most effective tool, but other people consider the radio as the obvious winner. In my view, when it comes to the efficiency of communicating information, nothing beats television.
   Books have become information media at a very early time. I hold a view that the most important value of books is that they can be preserved for a long time. For example, researching documents which our forefathers left us are items of great historic significance. However, it is not convenient for people to carry piles of books. Besides, with the fast development of modern society, the update for books is far from meeting the social demands for the latest information. Radio and television are products of industrialization and informatization. They both can be used for spreading latest information and even some instant messages. Radio is portable for individuals to carry around, while television is able to provide information satisfying both people's eyes and ears. What is more, with the development of modem techniques, an increasingly number of portable televisions have been invented and put into production. It seems that television is the most effective way for communicating information. Nevertheless, because the information, which is conveyed via radios and television, draws more attention on current events, and often cannot analyze a topic deeply, people still need books to add essential supplements.
   In conclusion, books, radio and television each have their own advantages and disadvantages, and have an irreplaceable place in human history. Among these three media, television is the most effective one now. However, it is possible that with the rapid development of modern techniques, scientists will invent a comprehensive media tool which can absolutely meet various demands for communicating information.
