Passage 4

The appeal of advertising to buying motives canhave both negative and positive effects. Consumersmay be convinced to buy a product of poor qualityor high price because of an advertisement. Forexample some advertisers have appealed to people’sdesire for better fuel economy for their cars byadvertising automotive products that improve gasoline mileage. Some of the products work. Others are worthless and a waste of consumers’ money.

Sometimes advertising is intentionally misleading. A few years ago a brand of bread wasoffered to dieters (节食者)with the message that there were fewer calories (卡路里)in everyslice. It turned out that the bread was not dietetic (适合于节食的). But there were the samenumber of calories in every loaf.

On the positive side, emotional appeals may respond to a consumer's real concerns. Considerfire insurance. Fire insurance may be sold by appealing to fear of loss. But fear of loss is thereal reason for fire insurance. The security of knowing that property is protected byinsurance makes the purchase of fire insurance a worthwhile investment for most people ifconsumers consider the quality of the insurance plans as well as the message in the ads，they will benefit from the advertising.四级准考证查询
