Televisions and movies play an increasingly important role in people's daily life, due to the various content of them, some people hold the viewpoint that they influence young people mainly in a negative way. However,  most youngsters focus their attention on studying, promoting personal skills rather than watching TV. Therefore, the televisons and movies can not affect them so much.First of all, the contents of TV programs and movies tend to spread positive information to audiences. The movie directors know that TV influence people unconsciously and some young people will imitate the practices in the movies. So they avoid using negative elements in their products. The function of  villains in the movies are procucing the conflicts which can attract audience, and movies are all have a happy ending, just like the heros are highly respected and evils are cast aside by people. All of these affect young people that evil is prohibited and people should do good. Besides, some popular TV programs invite some famous people, and they will tell their own experiences to yong people, which will inspire them, encourage them in a very positive manner.Second, there are many factors influence the behaviors of yong adult, and watching TV are not the primary one.  Behaviors of family members, teachers and friends are all affect them in a subconscious way. We know that young adults have a pretty hectic life, they need to spend whole day in school, and after school they need to do their homework and take some extra class. So when do they have time to watch TV or movies? Therefore, this is just a little part of their life, and the individual personalities and behaviors are combined effects, only few factors can not have decisive effects. Besides, the national department of radio film and tevelision is playing an important role in supervision, which will limit them to use the negative element. Also, parents are have a similar function. While I admit that there still exist many violence, sexes, and false information on tevelisons and  movies, I think young adults will refrain from seeing them when the those departments do really responsible.  Therefore, with so many elements influence the development of personalities and individual behaviors, we can say that the television are only part of them, so they could not influence people in negative way, instead, they are a fairly positive factor.
