13．Have your parents ever caught you misbehaving--fighting with peers，coming home late or playing computer games when you were supposed to be doing your homework？How did they react？Did they try to talk to you or just yell at you？
Parents used to rely on physical punishments like pushing or spanking（打屁股）to control their children's behavior，which has been proven to be very harmful．Therefore，most parents now choose to simply yell，thinking that language probably won't hurt as much．But is that really so？
Using harsh words such as"lazy"or"stupid"to insult teenagers is just as harmful as hitting，according to a new study carried out at the University of Pittsburgh，US．"It cannot reduce or correct their problem behavior，"said Professor Ming-Te Wang，leader of the study．"On the contrary，it makes it worse．"
The study's subjects were 976 two-parent families with teenage children．Researchers asked the kids about their behavior problems while questioning parents about how often they had cursed （咒罵）or yelled at their kids．
Nearly half of the parents admitted that they'd shouted at their children in the past year．Researchers noted that the kids whose parents used more harsh words experienced more behavior problems afterwards，including fighting，stealing，lying as well as symptoms of depression （抑郁）．
"Adolescence is a very sensitive period when kids are trying to develop their self-identities．When you yell，it makes them feel they are not capable，that they are worthless and useless，"Wang said．"This may explain why so many parents say that no matter how loud they shout，their teenagers don't listen．"
While harsh yelling can stop bad behavior in the moment，it doesn't teach children to behave how parents want them to．What parents need to do is praise their children for good behavior．If parents really need to punish their kids，they should try things like taking away smart phones and reminding them that good behavior will get them back．
