摘　　要：福柯提出了“话语即权力”的概念,在跨种族婚姻中的弱势一方通常是被边缘化的“属下”,缺少自由表达自己观点的话语权力。本文采集了美国印度裔现代女作家裘帕·拉希莉作品中六组跨种族婚姻夫妇的对话建立小型语料库,结合韩礼德功能语法中的人际功能理论,借助随机森林回归算法对选取语料进行定量和定性的分析,探究在跨种族婚姻中性别与族裔对语言使用的影响。研究结果表明,跨种族婚姻中不同人群的语言使用存在显著差异,男性与英美裔群体更倾向于使用祈使语气和高等量值的情态动词;女性和少数族裔群体则更多地选择疑问语气、感叹语气和中低等量值的情态动词。这些差异一定程度上反映了美国的社会文化中的男性中心主义与种族歧视影响。The theory of“discourse power”is proposed by Foucault.The disadvantaged community of interethnic marriage,the marginalized“subaltern”,usually lack the discourse right to express themselves.Focusing on utterances of six couples in Indian American writer Jhumpa Lahiri’s novels,this thesis creates a corpus.Combined with the interpersonal metafunction of Halliday’s systemic-functional grammar,the research offers quantitative and qualitative analysis by using Random Forest Regression Algorithm(RFA).The study aims to explore the language expression difference of interethnic marriage and the influence factors,including gender and ethnicity.It is found that there are striking differences in their expression.Males and Anglo-Americans prefer imperative mood and a higher degree of modal verbs,while females and minorities prefer interrogative and exclamatory mood and relatively lower degree of modal verbs,which partly proves the impact of phallogocentrism and racial discrimination in America.
