The evidence for harmony may not be obvious in some families.But it seems that four out of five
young people now get on with their parents, which is the opposite of the popularly held image (印象)
of unhappy teenagers locked in their room after endless fami
ly quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more
harmonious than it has ever been in the past."We were surprised by just how positive today's young
people seen to be about their families," said one member of the research team."They're expected to be
rebellious (叛逆的) and selfish but actually they have other things on their minds; they want a car and
material goods, and they worry about whether school is serving them well.There's more negotiation (商
议) and discussion between parents and children, and children expect to take part in the family
decisionmaking process.They don't want to rock the boat."
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat
their children as friends."My parents are happy to discuss things with me and willing to listen to me,"
says 17yearold Daniel Lazall."I always tell them when I'm going out clubbing.As long as they know
what I'm doing, they're fine with it." Susan Crome, who is now 21, agrees."Looking back on the last 10
years, there was a lot of what you could call negotiation.
For example, as long as I'd done all my
homework, I could go out on a Saturday night.But I think my grandparents were a lot stricter with my
parents than that."
Maybe this positive view of family life should not be unexpected.It is possible that the idea of
teenagers rebellion is not rooted in real facts.A researcher comments, "Our surprise that teenagers say
they get along well with their parents comes because of a brief period in our social history when
teenagers were regarded as different beings.But that idea of rebelling and breaking away from their
parents really only happened during that one time in the 1960s when everyone rebelled.The normal
situation throughout history has been a smooth change from helping out with the family business to
taking it over."
