从《敦煌变文集》“V＋（X）＋了”中的“V”的产生看“了1”“了2”的产生

“了1”的形成是一种合力的结果，从“V＋了”后添宾，从“V＋O＋了”前移，“V＋O＋了”中“了”的句法位置，相关句法结构的影响等都可能导致“了”的虚化。考察《敦煌变文集》中的“V＋（x）＋了”，其中的“V”的不同类型影响到了．的产生方式。在吴福祥（1998）的分类基础上，我们认为还应该考虑动词的及物性，“了”首先是在“Vi瞬间＋了”组合中发生虚化的。“了，”“了：”都是从表“终了、完结”义的动词“了”发展而来，但从事态助词“了。”到“了：”的演变过程和“了。”的功能研究还有待深入。

On Appearance of "Le-1" and "Le-2" from "V+(x)+Le" in Dunhuang Bian Wen Ji

The appearance of "le-1" is the result of combined influences."V+le" follows an object,the transfer of "V+O+le",the position of "le" in "V+O+le" and other relative sentence structures influence the meaning of "le".The essay studies the structure of "V+(X)+le" in Dunhuang Bian Wen Ji,and draws the conclusion that the different types of "V" influence the appearance of "le-1".On the basis of categories offered by Wu Fuxiang in 1998,the features of transitive verb should be considered.The meaning of "le" changed in the combination of "Vi+le".The meaning of "Le-1" and "le-2" are developed from the word "le" with the meaning of "accomplishment" and "fulfillment".The process of transformation of "le-s" to "le-2" and the function of "le-s" are worthy to study.
