本文研究现代汉语的“Ｎ的ｖ”与上古汉语的“Ｎ之Ｖ”，认为二者性质基本一样，都不是名词性的偏正结构，而是某种主谓结构处于非独立的、指称的状态下的一个变体。其中的“的”和“之”也不是名词性们正结构的形式标志，而是这种主谓结构处于非独立的、指称的状态下的一个非强制性的形式标记。现代汉语的“Ｎ的Ｖ”是上古汉语“Ｎ之Ｖ”的直接继承者。 This paper studies the “N v” of modern Chinese and the “N V” of ancient Chinese. It is considered that the nature of the two is basically the same as that of N, and neither of them is a nominal partial structure, but rather a nonproprietary A variant of the state. The “or” and “the” are not normative signs of the nominal structure of the nouns, but rather an optional form of marking that the subject-predicate structure is in a non-independent and alien state. Modern Chinese “N of V” is the immediate successor to the ancient Chinese “V N”.
