Radio and television are very popular in the world today． Millions of people watch TV．Perhaps more people listen to the radio．The TV is，of course，more useful than the radio． On TV you can see and hear what is hap-pening in the world．Now radio is still with us． And the number of listeners is becoming larger． One reason for this is the invention of the transistor(半导体) radio． A transistor radio is sometimes very small． It is very easy to carry． You can put one in your pocket and listen to it on the bus or on your bike when you go to work． It is better．for blind people． The sight(视力J) of many old peo-ple is not good enough to watch TV． Then，when people are working，they can't watch TV， but they can listen to music or news over the radio． What-s more，radio is much cheaper than TV．
