Radio and television are very popular in the world today. Millions of people watch TV. Perhaps more people listen to the radio.
现在，收音机和电视机在世界上都很流行。数以百万计的人看电视。也许听收音机的人更多。
The TV is more useful than the radio. On TV we can see and hear what is happening in the world. But radio isn't lost. It is still with us. That's because a radio is very small, and it's 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 school.
电视机比收音机更有用。在电视上我们可以看到和听到世界上正在发生的事。可是收音机并没有消失，它还和我们在一起。这是因为收音机很小，便于携带。你可以放在口袋里，在坐车或汽车上学时收听。
