【摘要】 本文以评价框架为理论基础，对比分析中美两国新冠疫情报道中评价资源的分布情况及其映射的中美国家形象。研究表明，在态度资源中，中方偏向使用鉴赏资源描述抗疫措施的及时有效，彰显中国政府负责任的国家形象；美方则更倾向使用消极的判断资源表达偏见，激发反华情绪。在介入资源中，中方的扩展性多声策略和美方的压缩性多声及单声策略形成鲜明对比，彰显中国交流沟通的姿态和开放的国家形象，与美国政府失信、不负责任的形象形成反差。级差资源方面双方差异最小，中方通过弱化意义表达力度缓解矛盾，塑造包容的外交形象；而美方使用强化意义表达力度反映了美国政府及官员在抗疫方面不务实和盲目乐观的态度。本研究为通过评价资源建构中美两国国家形象提供了新的思路。更多还原

【Abstract】 This paper makes a comparative analysis of the distribution of the appraisal resources in Chinese and American news reports on COVID-19 pandemic from the perspective of the appraisal framework. It is revealed that in terms of the attitudinal resources, Chinese media tends to express the promptness and effectiveness of the measures for fighting the pandemic through appreciation resources to show the responsible image of the Chinese government, whereas the American media prefers to use negative judgment resources to deliver prejudice and evoke anti-China sentiment. In terms of engagement, Chinese media adopts the dialogic expansion resources to convey negotiable stance, shaping the open and inclusive image of the Chinese government, while dialogic contraction resources are employed in American news reports, mirroring the incredibility and irresponsibility of the American government. It is also found that the distribution of graduation resources differs slightly in Chinese and American reports in that both prefer employing“force”. However, the former alleviates contradictions through softening resources, which shows the inclusive diplomatic image of the Chinese government, and the latter relies on intensification to betray that the American government and officials are not pragmatic and unrealistically optimistic in combating the pandemic. This study provides new insights on the construction of the national images of China and the United States through evaluative resources.更多还原
