摘要：Critical discourse analysis (CDA) is an effective method of the discourse analysis. It is aimed at analyzing the special relationship between power and the traditional ideology in implied discourse. Traditional discourse analysis always analyzes the structure and composition of discourse in terms of linguistic features, CDA makes language analysis more creative. It deeply explores the inherent potential of language and systematically interprets the deep meaning of discourse. This paper will take the specific corpus, namely Trump's TV speech, as the language material, Halliday's systematic functional grammar as the theoretical basis, and physicality, modality and personal pronoun as the framework. This paper studies how speakers in political speech use language to shorten the distance between people and win people's affirmation and support from the aspects of transitivity analysis, modality analysis and personal pronoun.
