【摘要】 本文基于语料库考察英语专业学习者作文中情态动词语义的发展路径,研究发现:(1)我国专业英语学习者作文中情态动词的使用存在严重的过多使用和过少使用现象,教材中较早涉及的表达责任、义务等情态语义的情态动词如can、will和should显著超用,而表达礼貌温和、委婉等认知语气的情态动词如might、could、would等则显著少用;(2)学生作文中情态句式的使用频次也呈现出责任、义务情态句式过多使用而认知情态句式过少使用的现象,且在"有灵主语+VM"这一责任情态句式中过多使用人称代词作为情态动词的主语;(3)认识情态表达句式的使用频次并不会随着学习者语言水平的提高而明显增加。更多还原
