听力原文：W: Bob, Have you seen any movies recently？
M: Yes, I've seen a few.
W: Have you noticed any people smoking in the movies？
M: I wasn't paying special attention to that, but I am sure I saw some actors and even actresses smoke in movies.
W: The World Health Organization says young people are likely to think smoking is a good thing if they see actors smoke, and that cigarette companies use movies to sell more tobacco, especially to young people.
M: That's true. Mass media may have some negative effects on viewers.
W: Now, people are calling for moviemakers to remove cigarettes from their films.
M: Do you think it's necessary？ Movies reflect social reality, after all. If the actors never smoke in films, the films may seem unreal.
W: You know, the W-H-O estimates that tobacco kills five million people a year, and that number is growing.
M: That's terrible, but do you think we can attribute it solely to the movies or to other media as well？
W: At least partly. In many countries, including India and the United States, it is illegal to try to sell tobacco on television.
M: But it is legal to show smoking and cigarettes in the movies.
W: Yes, it is reported that tobacco companies even give famous actors a free lifetime supply of cigarettes. These actors often have good-looking bodies. That makes young people think smoking will be good for their health.
M: Too bad. That's really misleading.
W: Sure, perhaps, a law should be passed that there shouldn't be too much smoking in mass media.
M: Absolutely.
