Subjective Research Of Modal Particles“BA”“NE”“A”“MA”“MA”“HA”

Modal Particles have been one of the important means to express one’s ideas or feelings, from the ancient ZAI HU YI to A BA NE, the system of Chinese modal particles has been rich, especially the modern Mandarin, such as A LA MA NE BA and so on. The dialectal modal particles are also a large branching, like HA LEI DUO. In order to entirely investigate the modern Chinese modal particles, we choose "BA""NE""A""MA""MA""HA" to research, for they are representative. Among them,"BA""NE""A""MA" are typical, while "MA""HA" are atypical;"BA""NE""A""MA""MA" belong to Mandarin, while "HA" belongs to dialect. That’s the reason why we just research them.Based on the theory of grammar, this paper mainly discusses the six modal particles above in the third chapter from the affect of speaker, and in the fourth chapter from the epistemic modality of speaker. In the fifth chapter, we probed into the causes of the subjectivity of modal particles.
