To explore the passive form, disposal construction, causative mood in the Dunhuang Bianwen, this dissertation researches the three structures from the point of view of syntax and semantics. It analyzes the relationships between the three syntactical structures and generalizes them as the semantic aspect of cause. Not only does this dissertation thoroughly gather all three sentence-patterns examples, but also, on the basis of accurate description and quantitative statistics, this dissertation constructs a rounded semantic system. Simultaneously, with the help of academic findings, this dissertation analyzes the semantic features of the three structures in Bianwen. The focal point of this dissertation comes through research on the relations between the three structures. While analyzing and understanding the differences, this dissertation gives a theoretical account referring to the language phenomena. Furthermore, it explores some original ideas when comparing the passive form with the disposal v construction and causative mood, differing passive form from disposal construction and causative mood, and explaining factitive and passive . The research in this dissertation not only helps us understand the characteristics among Chinese passive form, disposal construction, causative mood and its correlation, it also develops our understanding of language characteristics from the Bianwen period. [Key words] the Dunhuang Bianwen, passive form, disposal construction, causative mood, semantics, cause

本文以敦煌變文中的被動式、處置式和使役式作為研究對象，在對變文中 的這三種句式分別進行句法、語義分析的基礎上，再把它們共同納入“致使＂ 這一句法語義範疇之內，探討彼此之間的聯繫與區別。 本文窮盡收集了變文中這三種句式的全部用例，在進行準確描寫和定量統 計的基礎上，借鑒學術界現有的研究成果，構建了一個完整的語義體系，重點 分析了變文中這三種句式各個組成部份的語義特點。文章的重點與亮點主要體 現在對變文中這三種句式的關係研究方面：在分析歸納變文中這三種句式之間 異同的基礎上，對其中所涉及到的一些語言現象進行了理論解釋，在分析變文 中的被動式和處置式共同區別於使役式的特點、被動式區別於處置式和使役式 的特點、使役動詞兼表被動的原因等問題時提出了一些創見。 本文的研究既有助於更好地瞭解漢語被動式、處置式和使役式這三種句式 的特點及其相互關係，也有助於更好地瞭解變文時期語言的特點。 關鍵詞：敦煌變文 被動式 處置式 使役式 語義 致使
