本文研究汉语口语中建议功能的表达。主要关注汉语口语中，语言形式表达建议功能时所需的支持条件、影响语言形式选择的情景要素，以及语篇中实现连贯的表达手段问题，以供汉语作为第二语言的学习与教材编写需要。 本研究通过视频语料转写，从60万字（604585字）的汉语口语语料中，共提取出50种用于表达建议功能的语言形式。根据语言形式在语境中实现建议功能表达所需要的语义条件和情景条件支持情况，这些语言形式在建议功能的表达中可分为三类：1. 能够实现情景自足，独立表达建议功能的形式（如用于表达建议的主从句：我建议/提议+从句）。2.语言形式（如无标记肯定祈使句）存在多重功能，是否表达建议功能需要语义条件和情景条件的支持；3.部分形式一般不表达建议功能，在表达建议功能时完全依赖情景条件的支持。在多人参与的会话中，语义条件、情景条件常需要通过一系列的上下文条件获得保持和延续。 建议范畴具有原型范畴的特征，与命令功能、请求许可功能、询问陈述功能、酬应客套功能之间既有区别，又有交叉。建议范畴存在七个内部成员，成员与表达形式之间存在着聚合关系。在建议功能的表达中，有六类情景要素与建议提出者的语言形式选择显著相关：建议提出者与建议接受者双方的权势关系、建议强度、建议预期、上文情景条件、建议策略、建议结果。通过其在影响语言形式选择时的不同表现，即区别特征的“值”，可描写出提议类建议、商榷类建议、劝说类建议、指示类建议、提醒类建议、催促类建议、叮嘱类建议等建议范畴成员。 综合语言形式、语言形式表达建议功能的支持条件、语言形式表达建议功能的范围和特点，本研究对无标记肯定祈使句、表达征询意愿的附加问句、助动词、语气词“吧/嘛/呗”、假设复句等语言形式对建议功能的表达手段进行了归纳，还讨论了一般不表达建议功能的语言形式在表达建议功能时的支持条件和表达特点。另外，本文还归纳了三类实现建议功能连贯表达的衔接手段。 本研究同时考察话语功能及其所在的情景、所使用的语言形式，将三者作为建议功能的三个维度明确关联。对语言形式及其表达条件的研究成果可以用于编制真正面向提高学习者交际能力的汉语中高级口语教材、教学大纲等。

The research is origin from the needs of teaching Chinese as a second language (TCSL), based on the basic theory of Function Linguistics, to study the utterance of advisement in Chinese oral language through analysis of the materials of Chinese oral Language. The research extract forms of advisement utterance from 604，585 characters corpus. Researchers pick all the advisement function utterance from the corpus，extract linguistic forms which is used to express advisement function by Chinese native speakers and analyze their supporting semantic/ context situation， conclude the performing devices of the advisement function. The result of the research can be used by learners who study Chinese as a second language and the editors who compile textbooks for Chinese second language learning. In the methodology of this paper, 50 kinds of language forms of expressing advisement functions were extracted， and their commonality， multiple functionalities and expression scopes were analyzed. This article also discusses the semantic and situational conditions which are necessary to support the advisement functions expression. Through the examples of the utterances of the advisement categories in the form of language， this paper summarizes the family resemblance in the advisement category and summarizes the correspondence and aggregation between the advisement functional categories and the linguistic forms. Based on the above analysis results， the study uses several linguistic forms which are commonly used to express advisement functions such as unmarked affirmative imperatives， auxiliary verbs for advisement functions， imperatives with questions， auxiliary， modal particles that express the advisement function to describe the performing devices of the advisement function. The research also describes the conditions of the scenarios to realize the advisement function. The research takes the situation/ form/ function as three dimensions of oral language expressions. The result of the research can also be used in editing the teaching materials and language teaching syllabus to help the second language learners enhance communication ability.
