In previous systemic functional studies of modality in Chinese, the systems of types and degrees of modality have been discussed; however, the system that characterizes the realization of types and degrees of modality has been largely neglected, and realizations of modality have not been systematically explored. This paper explores the system of MODALITY in Chinese and realizations derived from the system from the perspective of Systemic Functional Linguistics. In this study, the systems of types and values of modality in Chinese are re-examined. The system of types of modality excludes usuality, since it distinguishes itself from modalization and modulation essentially. The system of values of modality is treated as a cline. More importantly, the study gives a systematic and comprehensive description of the system of MANIFESTATIONS that describes the realization of modality, which distinguishes among explicitly subjective, explicitly objective, and implicitly subjective realizations of modality. The present study is the first attempt to systematically and critically examine the systems of types, values, and realizations of modality in Chinese. It may contribute to a better understanding of modality in the particular language of Chinese, and may lend support to system-based typology, supplementing structure-based typology.

在以往的汉语语气系统功能研究中，已经讨论了语气的类型和程度的系统；然而，表征模态类型和程度的系统在很大程度上被忽视了，模态的实现也没有被系统地探索。本文从系统功能语言学的角度探讨汉语情态系统及其衍生的实现。本研究重新审视汉语语气的类型和价值体系。情态类型系统排除了惯常性，因为它本质上区别于情态化和调制。情态的价值体系被视为一个cline。更重要的是，该研究对描述模态实现的 MANIFESTATIONS 系统进行了系统和全面的描述，该系统区分了显式主观、显式客观和隐式主观的模态实现。本研究首次尝试系统地、批判性地考察汉语中情态的类型、价值和实现系统。它可能有助于更好地理解汉语特定语言的情态，并可能支持基于系统的类型学，补充基于结构的类型学。和情态在汉语中的实现。它可能有助于更好地理解汉语特定语言的情态，并可能支持基于系统的类型学，补充基于结构的类型学。和情态在汉语中的实现。它可能有助于更好地理解汉语特定语言的情态，并可能支持基于系统的类型学，补充基于结构的类型学。
