听力原文： Woman: Isn't advertising really a kind of lying? Man: I don't think so. Quite often people do try to get away with those types of things, but the Federal Trade Commission is always very quick to jump on them to force them to show evidence to back up the claims. Woman: I mean in your work. I mean, don't you actually tell lies to get people buy things? Let me give you an example. You know, a movie star says that she uses—a starlet—says that she uses a certain kind of soap every night to make her skin look beautiful and, of course, she doesn't use it at all, or hardly ever. Man: I think if you go back very recently, just within the last year, you'll remember that one of our famous singers and actors and was uh… called down for just that very thing, where he endorsed a product which he didn't use and had to take back what he said in his endorsements. Woman: I see, so what you're saying is that you're freed to be honest in the profession. Man: In some cases that may be true. I won't deny that. Woman: Well, you've been in the ad business for nearly 15 years. What kind of work do you find most interesting? Man: I would say, developing new markets, or not so much new markets, but when you have a product which previously people didn't perceive that they needed, but it is an advancement or an improvement over what people previously used, and are able to educate people and inform. them of a particular thing, and they discover it will make their life better and it is something that they could use. Woman: To try to make them understand what's going on with a new product? Man: Basically, that's it. This is where a lot of the progress or the amenities in life which we take for granted now… this is how they originally developed. Somebody thought of a new idea and convinced people that it was something they needed and after a period or time, it became what they considered a necessity. In other words, the advertising as a promotion will make people aware of a product, but… the product’s own worth will determine whether or not it's something that people will bring into their daily lives. Woman: And… I suppose that if it endures over a long period of time that shows that the product really does have a stable value and that you're not lying. Man: Well, I think that's a fair assumption… I won't try to tell you that in promoting things, people never lie, but the initial promotion simply gets people to try a product for the first time. And then if the product itself has any merit, then people will continue to use it. So, the quality of a product will determine whether it has any staying power. 27.
