Some time ago, a store advertised rebuilt vacuum cleaners of a nationally known brand at the absurdly (荒谬地) low price of $ 12.50. Why was this done? Surely the store could not【36】to sell good vacuum cleaners【37】this price. As a matter of fact, any customer who tried to buy one would find it was'【38】'. He would be told that the one in the window was 'the only one left' and had to remain on【39】, or that 'it had been sold' before he entered the store. The【40】aim of this kind of advertising is to lure (引诱) customers【41】the store for the purpose of【42】them to buy some other higher price brand. This is called 'bait (诱饵) advertising'. In【43】the $12.50 vacuum cleaners, the manufacturer whose name was used went to【44】and obtained an order【45】the store to employ the brand name for that purpose. Why did the managers of the manufacturing【46】go to such lengths to【47】this abuse (恶习) in advertising? They realized that misrepresentation of their firm's name was sure to【48】public confidence in their products. The honest businessman wants to keep his customers【49】so that they will return to buy again and again. He builds good【50】by conducting his business on a【51】of trust and confidence.【52】, he wants other businessmen's advertising, as well as his own, to【53】the public's respect because he realizes that anything that【54】confidence in advertising tends to injure honest advertisers as well as the fraudulent (欺诈的)【55】. That is why businessmen have set up their own agencies to police advertising. (41)
