.4 Read the text. Put the paragraphs into the correct order. Then answer the questions below.
A.
B. The problem with this is that parents give their sons and daughters no cultural values. So what happens in the TV programme? Some problematic British teenagers go and live with parents in different parts of the world. They live with families that believe in traditional discipline and cultural values. In Ghana, Jamaica, Botswana and the southern US state of Alabama, the teenagers have the experlence of living with parents who want and expect good behaviour and hard work. The results are interesting. In the end, the British teenagers seem to prefer having strict parents! B. The director of the programme, Andrea Wiseman, explains why they are making it. She thinks that in the United Kingdom teenagers pay no attention to adults. They don't want to do well at school. They think they can do what they like and they are only interested in new fashions and Hollywood celebrities.
C. What's the problem with British teenagers?'Many British newspapers and TV programmes are asking this question at the moment. A lot of people are saying that there are problems with teenagers at school, on the streets and In their homes. Why? VWhat, or who, Is responsible for these problems?
D. Why are British teenagers like this? Wiseman says it's because their parents give their children everything they can. But they give their children no limits, no rules, no discipline because they want their children to be 'free'. They don't tell their children to work hard because they don't want their kids to have any stress. E. A recent BBC television series explores these questions. It's called The world's strictest parents'. Is that because British parents are very strict? Just the opposite, it seems.
1.) What negative things do British teenagers do?
