听力题 M: Mind if I switch channels? Those TV commercials are killing me. W: How can you say that? Watch: "Take Toshiba, take the world." Fantastic! M: If I were you, I wouldn''t trust those commercials. W: Why not? M: In today''s business world, supply usually outnumbers demand. There is great competition between manufacturers of the same kind of product to attract customers to their products. They do this by advertising. W: What is wrong with that? Those are powerful products you can depend on. M: Manufacturers often spend large sums of money on advertisements. Sometimes they even spend more on ads than on making quality products. And the cost of the ads is built into the products. W: Maybe so, but I still think advertising serves a useful purpose. It tells me about new products. M: To remind the customer of the name and the quality of their product, the manufacturers advertise in the newspapers and on posters. They pay for songs about their product in commercial radio programs. They employ salesgirls to distribute samples. They organize competitions, with prizes for the winners. Most important of all, they have advertisements put into TV programs. When they make TV commercials, they use scientific methods to learn what you''ll like and buy. W: Are you telling me those cute little children biting into Big Macs are part of a scientific project to get people into McDonald''s? M: Sure. Advertisers don''t bother with facts any more. They just want you to fall in love with their product. Many people buy a particular product because they think it is the best. They usually think so because the advertisements say so. They never pause to ask themselves if the advertisements are telling the truth.
