[speaker001:] Did you watch the movie program on Channel 6 last night?
[speaker002:] Yes, I did. It is a horrible movie.
[speaker001:] I wonder why TV programs often show much violence.
[speaker002:] Actually, more and more people have realized that violence on TV may lead to the increase of crime rates among teenagers.
[speaker001:] They are especially harmful to teenagers.
[speaker002:] But anyhow there are many worthwhile programs.
