A new TV series in England，Away from it all，has surprised everyone by becoming a huge success with young people across the country．Its success is surprising because the series is about the relaxing lifestyles of people who live in the country．There is none of the action that we usually see on TV today．There are also no stressful moments，busy offices or crowded cities．Away from it all is set in the peaceful English countryside and tells simple stories about people’s kindness．
The director of the TV series says that its success is a sign of teenagers suffering from stress．They say that watching Away from it all helps teenagers forget about the pressures(压力)of exams and homework，and the troubles that fill the world today．They also say that it’s a good sign of today’s young people switching to(转到)happier TV series as it shows they would like a happier and healthier world．
Although the series’success might have a good side，many teachers and parents are worried，however．They say that some of their students and children are becoming couch potatoes(终日泡在电视机前的人)and are using Away from it all as an excuse for not completing homework．Some children have even refused to learn for exams because they say that they can only achieve personal happiness by avoiding(避免)stressful situations completely．
And what do the experts(专家)say? Paula Ray，a doctor of education，says that TV can influence children’s lifestyles．But she says that if a child reacts strongly，it’s likely that there are other reasons for his change in behaviour．She says that there is nothing wrong with watching Away from it all but suggests that parents should make sure their children know TV is not the same as real life，
