Discourse marker has a close relationship to metadiscourse, and it is different from each other to some extent.

话语标记语和元话语既相互区别又相互联系。

Chapter one, the Preface. We give a brief introduction of the research situation on discourse marker and turn-taking.

第一章绪论简要介绍了话语标记、话轮转换的研究现状及对相关概念进行界定。

We should, according to the context in which a discourse marker lies in, adopt one of these methods to pursue the perfect treatment.

我们应根据话语标记语所处的语境来从中选择最恰当的处理方法。

According to the different connection with the textual structure, we divide the discourse marker into structural marker and communicative marker.

根据话语标记语与整个语篇结构的关系不同，我们将其划分为结构类话语标记语和交际类话语标记语两大类。

Discourse marker is word or phrase that relate the present discourse to the prior one, whereas metadiscourse contains all the things that has nothing to do with the propositional content.

话语标记语是标示当前话语和前述话语之间序列关系的词或短语，元话语包括所有不涉及话题内容的东西。
