     Until recently, women in advertisements wore one of three things-an apron, an attractive dress or a frown.

Although that is now changing, many women still feel angry about offending advertisements. "This ad degrades

women." they protested (抗议). Why does this sort of advertising exist? How can advertisers and ad agencies

still produce, sometimes, after months of research, advertising that offends the consumer?

     The ASA, the body which deals with complaints about print media, is carrying out research into how women

feel about the way they are pictured in advertisements. Its conclusions are likely 10 be what the advertising

industry already knows: although women are often annoyed by the ads, few feel strongly enough to complain.

     Women are not the only victims of poor and boring stereotypes (老套)-in many TV commercials men are

seen either as useless, childish fools who are unable to perform the simplest household tasks, or as inconsiderate

fellows, always on the lookout for an escape to the pub. But it is women who seem to suffer more from the

industry's inability to put people into an authentic present-day situation. Yet according to Emma Bennett, director

of a London advertising agency, women are not aggressive or extremely angry about those stereotypes and

sexist (歧视妇女的) advertising. "They just find it annoying or tiresome."

     She says that it is not advertising's use of the housewife role that bothers women, but the way in which it is

handled. "The most important thing is the advertisement's tone of voice. Women hate being insincerely praised

or given desperately down-to-earth common-sense advice."

     In the end, the responsibility for good advertising must be shared between the advertiser, the advertising

agency and the consumer. Advertising does not set trends but it reflects them. It is up to the consumer to tell

advertisers where they fail, and the process of change will remain slow until people on the receiving end take

the business seriously and make their feelings known.
