Read the passages carefully. Then answer the questions.

I love TV. The first thing I do when I wake up is to switch it on. My favourite channel is the Cartoon Network. I watch TV three or four hours a day. My parents think it is too much and they are always telling me to study, read a little or do a sport. But TV is my favourite hobby. I’m addicted to my favourite progammes.

I know most teens don’t like watching the news, but I do. I like to know what is happening around our world. I also enjoy documentaries, especially about wildlife. I’m very curious about the way animals live and how to preserve their habitats. I also enjoy watching live shows and films, mostly comedies and thrillers. I watch TV two or three hours aday

I like TV as everybody else, but now that I’m older I am more selective about the programmes I watch. I used to watch cartoons all the time. Now I like watching the news and some games shows like “Who wants to be a millionaire?”, so I don’t really spend too much time in front of the box, an hour or two a day... Some programmes are educational and help us to useour imagination, but many are full of violence.
