本书试图运用多种理论，如认知语言学理论、语法化理论、语言类型学理论、韵律句法学理论等，全方位透视现代汉语完成体的共时变异和历时演变过程。具体探讨了补语"完"的内部划分、分布规律、语义指向、融合度等级、有界化差异等。对汉语史上的"完成"义动词或助词的历时沿革过程、完成体构式的历时衍生过程，以及汉语完成体和完成体构式的方言共性与差异进行了分析。最后尝试性地探讨了完成在汉语体貌系统中的地位和作用。 (The books tries to use many theories such as cognitive linguistics theory, grammaticalization theory, linguistic typology theory, prosodic syntax theory to analyze synchronic variation and diachronic evolution of the perfect aspect of modern Chinese. It specifically discussed internal partition, distribution rule, semantic orientation, integration level, bounded differences of the complement "Finish". It analyzed diachronic evolution process of notional verb or auxiliary word "finish", and diachronic derivatives process of the complete body, as well as similarities and differences of dialects of Chinese perfect aspect and the complete body. At last, the book tentatively discussed the position and role of "finish" in the Chinese aspectual system.)
