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. (23)
