文章通过对动结式在核心句、重动句、把字句、被字句、话题句中的分布限制的分析 ,说明其分布规律是动结式的概念结构的差别所驱动的。仅仅从动结式的动词和补语的论元以及补语的语义指向出发的还原主义研究取向不能完全解决问题。 The article analyzes the distribution restrictions of the verb - ending sentences in the core sentence, the repetitive sentence, the sentence, the sentence in the sentence and the topic sentence, and proves that the distribution rule is driven by the difference of the concept structure of the verb - knot. The reductive doctrine of departure from the argument of verb and complement and the semantic orientation of complement can not solve the problem completely.
