自上世纪末以来，国内外的文章分类理论基本上都以“表达方式”作为划分文章类别的依据。历史的沿革最后定格于“表达三体＋应用文”的分类体例。这个体例主导中学语文课本达６０余年之久，影响异常深广。百来年基本不变的文体教学分类体系，理论混沌、概念模糊，在实施中遗留 Since the end of the last century, the article classification theories at home and abroad have basically used the “expression method” as the basis for dividing the article categories. The evolution of history was finally fixed in the classification system of “expressing three bodies + applied documents.” This style dominated the middle school language textbooks for more than 60 years, and the impact was profound. The classification system of stylistic teaching, which is basically unchanged for a hundred years, is theoretically chaotic, and the concept is ambiguous.
