Television

Television is one of the greatest inventions of the 20th century. It's sometimes good and sometimes negative.
It's positive when learn, get information, watch movies and have fun. There are educational programmes, musicals and sports events.
It's negative when it shows violence or it's boring.

We have a remote control to change channels. We shouls use it to select good programmes.
TV demands silence and attention. With the TV on, there's lack of communication with our families and friends. At least, we should try to talk about TV programmes with them.
