元话语在话语的表达与理解中发挥着重要的作用。为了探究元话语的功能,本文利用关联性理论对元话语的推理制约性加以分析。研究结果表明,元话语对听话者的语境推理具有制约作用。元话语通过向听话者提示话题信息,限制了听话者的语境假设选择,制约了语境推理,引导了听话者的话语理解。由元话语构建的语境假设在某个语境中的推理制约性越强,其语境效果越显著,听话者为话语解读所付出推理努力就越小,元话语与语境的关联性就越大。
Metadiscourse plays an important role in the expression and understanding of discourse. In order to explore the function of meta-discourse, this article uses the relevance theory to analyze the meta-discourse inference constraints. The results show that meta-discourse has a restrictive effect on the speaker’s contextual inference. Meta-discourse, by presenting the topic information to the listener, limits the choice of the contextual hypothesis of the listener, restricts the contextual reasoning and guides the listener’s discourse understanding. The metaphorical construction of meta-discourse supposes that the stronger the inferential constraints in a certain context, the more significant its contextual effect is. The less hedging efforts are made by the hearer to interpret the utterances, the more the meta-discourse is related to the context The bigger
