世卫组织关于空气污染新闻话语的趋近化研究

A Study on the Proximization of WHO’s News Discourse on Air Pollution

基于趋近化理论,本文从空间、时间、价值趋近三个角度,探究世界卫生组织新闻话语中有关空气污染的话语如何通过策略实现其话语合法化的目的。研究结果显示,世卫组织的新闻话语在空间趋近化上,描写了以世界各国人民以及世卫组织等为主体的指示中心内部实体与以空气污染为主的指示中心外部实体的两方对立阵营,凸显空气污染在空间的物理威胁;在时间趋近化上,不同时态转换等话语形式的对比使用表明了空气污染在时间上的持续性;在价值趋近化上,指示中心内部实体积极意识形态与指示中心外部实体消极意识形态的对比描写,建构了意识形态的冲突物理化的可能性。世卫组织的新闻话语以空间趋近化策略为主、时间趋近化和价值趋近化策略为辅,建构其关于空气污染提议的合法性。本研究尝试拓宽趋近化理论的应用范畴和专门用途英语的适用理论。

Based on proximization theory,the paper explores how news discourses on air pollution of the World Health Organization(WHO)achieve the discursive legitimation purpose through strategies from perspectives of spatial,temporal and axiological proximization.The results show that the news discourses on air pollution of the WHO describe the two opposing camps of insidethe-deictic-center(IDC)and outside-the-deictic-center(ODC)and highlight the physical threat of air pollution concerning spatial proximization;regarding temporal proximization,the comparative use of discourse forms,such as different tense shifts,indicates the persistence of air pollution in the influencing period.In terms of axiological proximization,the comparison and description of IDC’s positive ideology and ODC’s negative ideology construct the possibility of physicalization of ideological conflict.The news discourses adopt spatial proximizaiton as a main strategy,and temporal and axiological proximization as auxiliary strategies.By means of proximization strategies from the three perspectives,the WHO achieves the purpose of legitimization of its proposals on air pollution.This study attempts to broaden the scope of application of proximization theory and the applicable theories of ESP.
