This paper aims to develop the description of move systems in Systemic Functional Linguistics based on dynamism in knowledge exchanges, that is, the possible move options made available at different points in an exchange concerned with the negotiation of information. Using conversational interactions in Khorchin Mongolian as examples, the paper argues that at different points in a knowledge exchange, both the speaker and the addressee’s knowledge of the information are at stake. The speaker may be positioned either as knowing or as not knowing the information; at the same time the addressee may be positioned either as knowing or as not knowing the information. It is also possible for the interlocutors not to be positioned either way. The move systems developed make it possible to discuss the options preselected and activated at different points in a knowledge exchange and the way interlocutors are dynamically positioned as an exchange unfolds.

本文的目的是基于知识交流中的动态性发展系统功能语言学中的移动系统描述，即，在与信息协商有关的交换中的不同点提供了可能的移动选项。以霍尔钦蒙古语中的对话交互为例，该论文认为，在知识交流的不同点上，说话者和收件人的信息知识都受到威胁。说话者可以被定位为知道或不知道信息。同时，可以将收件人定位为知道或不知道该信息。对话者也可能不以任何一种方式定位。
