Abstract: As a special form of written style, otherpreface is usually written by an authority in the relevant professional field, which is meant to introduce or comment on the content of the book. This paper selects thirtyfive otherprefaces in Chinese monographs as the corpus, and it firstly analyzes the generic elements which are generally contained in the monographs based on the Generic Structure Potential. However, because of the different relevance degrees of these elements in association to the readers understanding on the book itself, based on the Relevance theory, this paper gets the very relevant elements: field statement, book description, book features, book values and book weakness. The weakly relevant elements are: relationship statement, book author introduction and book author evaluation. The irrelevant elements are: prefacewriting motivation, selfabasement, research anticipation, publication congratulation and book recommendation.

Key words: otherpreface, Chinese monographs, generic elements, cognitive pragmatic, relevance degree

摘要： “他序”作为一种特殊的文体一般由相关专业领域中的权威人士撰写，多为介绍或评论本书的内容。选取35篇汉语学术专著“他序”为语料库，在语类结构潜势理论下分析“他序”一般包含的语类成分，这些成分与读者理解专著（内容）本身的认知关联度不同。以认知语用学为导向，在关联理论框架下，分析得出读者对专著认知的强关联成分有学科领域阐述、书本（内容）描述、书本特色、书本价值与书本不足；弱关联成分有关系陈述、著作者介绍和著作者评价；非关联成分有作序理由、自谦、研究期望、出版祝贺和书本推荐。
