I liked listening to the radio when I was young . I grew with the radio . I remember my grandparents had a small black radio when I was a little child . Every day at 6:00pm we listened to stories and had supper. There was a long story , but we could only hear a small part of it ----just 30minutes every day. It might take a few months to finish all the story . We listened to the story every night . And never got tired of it .

But as I grew older, I wanted to watch news reports on TV. I don’t want to listen to the radio any more. However my grandparents still want to listen to it . We have to have the radio and TV on at the same time. I watch TV and they listen to their stories on the radio.
