You see， in America， many people often spend their time sitting on a couch watching TV.
Some people will sit and watch TV for hours and hours without a break.
These people who do nothing except watch TV all day are called “couch potato”.
While watching TV， most of these people look so frozen that they almost look dead！
Everyone is sitting still with their eyes looking right at the same black box.because these people are addictive to TV， they do not take any exercise and usually get very fat.
So in many ways， these people look like real potatoes！
