摘要：This paper approaches advertisements on the basis of relevant theory. It elaborates how the advertiser as addresser in communication succeed in conveying his intention for publicity and how the recipient as addressee takes advantage of different types of relevant devices in reasoning out the communicative purposes from four different angles, namely, non-stereotypical interpretation of advertisements, psychological requirements of the recipient as addressee in advertisements, advertisements as explicit information and the situational approach to implicit meanings of advertisements. It aims at providing guidance for advertisement planning and translation by means of the exposure of rules underlying advertisements.
