I‘m big ang heavy,just like a box.I have a big face without a nose or eyes.I haven't any hands or
legs,either.The most interesting is that you can find many things on my face.You can listen to everyday's news;you can see films;you can see dancing programmes;you ccan travel with me to all parts of the world.People,old and young,like towatch me.Do you know what I am？
