答案：Teenagers often argue with their parents as they are growing up. Sometimes it's difficult to keep a good relationship. Teenagers think they have to obey too many rules. They think their parents care more about their study. And parents worry about their children's health problems because teenagers often stay up late. I think most parents and teenagers don't communicate enough and this often leads to the problems. They neither understand each other well nor trust each other. To solve these problems，both of them should open their hearts and talk more. Teenagers should share their thoughts with their parents and listen to their suggestions. Parents should trust their children more and show their worries honestly. Being open to each other can bring teenagers and their parents closer.
