Imagine you're sitting around with some friends playing video games and then someone mentions one of your favorite games. " Oh，that game is easy.So，it's not worth the time，" one of your friends says.The others agree.Although you enjoy the game quite a lot，not wanting to argue with them，you choose to agree with the crowd.
   You have just experienced what is commonly regarded as peer（同伴）pressure，also called peer influence.You will follow a certain kind of behavior，dress，or idea in order to be accepted as part of a group of your " peers".As a teen，you may have experienced the influence of peer pressure in many situations.
   We are always influenced by our peers.For teens，you may spend more time with your friends than with your family.
   According to Dr.Casey，teens are very patient and accurate （准确的）in making decisions on their own.However，when they make decisions in a hurry or in social situations，their decisions are often influenced by peers.In a recent study，teen volunteers played a video driving game ，either alone or with friends watching.The researchers discovered that the number of risks that teens took doubled （加倍）when their friends were watching，compared with when they played alone.
   Just as people can influence us to make unwise choices，they can also influence us to make good ones.Teenagers might take part in a volunteer project because their friends are doing it，or try to learn as much as they can to get good grades because the friends are doing well in studyjye.aig.In fact，friends often encourage each other to do things well.
