This book is a four-volume study on modern Chinese complex sentences, giving an overview and detailed analysis on the key attributes and three major types of this linguistic unit.Complex sentences in modern Chinese are unique in formation and meaning. The author proposes a tripartite classification of Chinese complex sentences according to the semantic relationships between the clauses, i.e., coordinate, causal, and adversative. The first volume defines Chinese complex sentences and makes detailed comparisons between the tripartite and dichotomous systems for the classification of complex sentences. It then thoroughly investigates causal complex sentences in their eight typical forms. The second volume analyses the coordinated type in the broad sense and the relevant forms, while the third focuses on adversative type, examining the major forms and implications for research and language teaching. The final volume looks into attributes of Chinese complex sentences as a whole, discussing the constituents, related sentence forms, and semantic and pragmatic relevance of complex sentences.The book will be a useful reference for scholars and learners of the Chinese language interested in Chinese grammar and language information processing.
