【摘要】 介入系统是评价理论中关于协商社会关系的语言资源,是态度表达的重要评估指标。对奥巴马五篇反恐演讲文本中的介入资源使用情况分析得出,奥巴马兼顾"对话性缩约"和"对话性扩展"两个维度,前者通过压制其他话语声音达到树立美国反恐权威,并鲜明地表达美国政府的各种态度和立场的目的,五篇文本尤其以"否认"资源居多;后者则部分给予目标受众话语空间,通过对其进行人际操控,拉近双方距离,实现双方互动,从而赢得他们的理解和支持,其中突出的资源形式为"引发"。更多还原

【Abstract】 Intervention system serves as a significant assessment index in appraisal theory applied to coordinate language resources indicating social relations and attitude expression. Based on the detailed analysis of the usages of interventional resources in the 5 selected texts delivered by Obama,it is found that Obama takes into account both"dialogic contraction"and"dialogic expansion". The former,with the majority of"deny"resources,sets up American’s anti-terrorism authority by suppressing the other voices,which clearly demonstrates the government’s attitudes and standpoints; while the latter gives the target listeners some dialogistic space,with the"trigger"as the prominent resource form,which wins their understanding and support by carrying out interpersonal control,reducing the distance between the speaker and the listeners and promoting the interaction between the both sides.更多还原
