‎(2008年广东卷)Parents and kids today dress alike,listen to the same music,and are friends.Is this a good thing？Sometimes,when Mr.Ballmer and his 16yearold daughter,Elizabeth,listen to rock music together and talk about interests they both enjoy,such as pop culture,he remembers his more distant relationship with his parents when he was a teenager. ‎“I would never have said to my mom,‘Hey,the new Weezer album is really great.How do you like it?’” says Ballmer.“There was just a complete gap in taste.” Music was not the only gulf.From clothing and hairstyles to activities and expectations,earlier generations of parents and children often appeared to move in separate orbits. Today,the generation gap has not disappeared,but it is getting narrow in many families.Conversations on subjects such as sex and drugs would not have taken place a generation ago.Now they are comfortable and common.And parent-child activities,from shopping to sports,involve a feeling of trust and friendship that can continue into adulthood. No wonder greeting cards today carry the message,“To my mother,my best friend.” But family experts warn that the new equality can also result in less respect for parents. ‎“There，s still a lot of strictness and authority on the part of parents out there,but there is a change happening,” says Kerrie,a psychology professor at Lebanon Valley College.“In the middle of that change,there is a lot of confusion among parents.” Family researchers offer a variety of reasons for these evolving roles and attitudes.They see the 1960s as a turning point.Great cultural changes led to more ‎ open communication and a more democratic process that encourages everyone to have a say. ‎“My parents were on the ‘before’ side of that change,but todays parents,the 40yearolds,were on the ‘after’ side,” explains Mr.Ballmer.“Its not something easily accomplished by parents these days,because life is more difficult to understand or deal with,but sharing interests does make it more fun to be a parent now.” Ⅰ.根据短文，写一篇30词左右的摘要。
