READING Task 1. Read the text and mark sentences True or False. Could you live without television for a week? Could you live without television for a week? That's what millions of people do every April as part of TV Turnoff Week, which is organized by anti-television groups like NoTV.com and White Dot. 'Sure, TV can sometimes be fun and exciting, especially when you're tired at the end of the day,' says Rudy Matthews form NoTV.com, 'but most of the time it^ prime s just boring. We want people to turn off the TV for a week and do something more interesting instead." You may be surprised how much television we watch. The average American family watches TV for 7 hours and 40 minutes every day and British men watch 27 hours a week (British women watch 'only' 24 hours). This means we spend over ten of our life watching TV- what a frightening fact! Many people are worried about how much TV children watch. Every American child sees 16,000 murders on TV before they are 18 and 20,000 adverts every year. Teacher Susan Walsh thinks this is a problem. 'Children in the USA spend more time watching TV than in school and that's very worrying." TV Turnoff Week started in the USA in 1995 and now happens every year in the UK, France, Holland and Australia. More than 25 million people have turned off their TV, so why don't you do the same? Mark the sentences True or False 1. People cannot live without TV for a week. 2. TV is exciting at the end of the day. 3. British women watch less TV than British men. 4. People watch TV for a half of their life. 5. Children should not watch so much TV according to the teacher Susan Walsh. 6. More than 25 million people have turned on their TV.​
