     Radio and television are very popular in the world today. Many people watch TV. We call them viewers.

Perhaps more people listen to the radios. We call them listeners. Older people call the radio the wireless (无

线电). And in conversation people call television TV or the "tele".

     The TV is, of course, more useful than the radio. On the TV you can see and hear what is happening. But

the radio is not disappearing. It's still with us. And the number of listeners is becoming larger. One reason for

this is that the invention of the transistor set (晶体管收音机) is sometimes very small. It's easy to carry. You

can put one in your pocket when you go to work. You can listen to the news broadcasts or radio lessons on

the bus. You can listen to them on your bike. You can put your own transistor set beside your pillow when

you go to bed. Besides radio broadcasts are better for blind people. And many old people's eyes are not good

enough to watch TV. When people are working, they can not watch TV. But they can always listen to music

on the radio. What's more, a TV set is usually more expensive than a transistor set.
