the double-edged sword-----advertisingit is widely accepted that nowadays advertising is a big part of our life.we can't imagine what the world look like without the colourful pictures and noisy but indispensible advertisement sound.perhaps darkness and loneliness would closely be the theme of our life.what's more,advertising serves as the most effective way to familiar with products and is so convinent to customers.the last but not least,advertising has developed to be the most efficient method to open a new market for commercial companies.some people douted the benefits of advettising and argue its shortcomings as follows:firstly,the amount of advertising is so unbearable that it could mess our life up to some extent.secondly,it has accounted for much precious time in our life waiting for programmes or other performance.as the result,it could slowly raise many customers aversion with the money invested in the advertising wasted.as to me ,i am inclined to support advertising if companies could arrange their advertising smartly.after all this is a information age and we should keep pace with the world development.
