摘要:广告在社会中发挥重要的作用。人们的日常生活都离不开广告并深深受到影响。伴随着社会的发展和经济的繁荣，这种影响将日益扩大。广告为了吸引购买者都会采用各种方法。所以广告语言必须要有说服力。

　　　作为沟通的一种形式，广告也是学者的研究对象。国内外学者从多方面领域和角度对广告语言进行探索。比如，从经济学、心理学、社会学和语言学。他们的研究是深刻而鼓舞人心的。

　　　本文从合作原则出发，通过案例分析分析化妆品广告。本文研究结果表明：通过违反合作原则，在特殊的语境下产生会话含义是广告的一大特色。文章指出广告巧妙地违反合作原则产生特殊说服效果。其中违反质量准则在化妆品广告中最为常用，其次是违反数量准则经常在著名化妆品广告中得到运用。关系准则和方式准则也在一些化妆品广告中得到应用，但是程度很难把握。
