Verificational research on theme and focus particles unique to modern spoken Japanese

本研究通过对“tte”、“datte”、“nanka”、“零助词”等研究较少的助词进行分析，揭示了现代日语口语中的主位助词和焦点助词与现代日语书面语中的主位助词的区别，并将结果收录在以下6篇论文中。前两篇是关于主题的，后三篇是关于聚焦的，最后一篇是关于聚焦的外围形式。(1)“Tte”表示主位--“tte”主位句的一个方面（高桥美奈子）（2）主位如何作用于主谓结构和修饰结构：日语口语中的定语描写（泽田广子）（3）焦点助词“datte”在日语口语中的作用和意义（中西久美子）（4）焦点助词“nanka”，表达所谓的减损（中西久美子）（5）现代日语中的呈现聚焦（Noda，Hisashi）（6）“toka”在现代日语中的用法（Lee，Jangmi）此外，我们记录并转录了自然语音，并将36个文本数据作为研究结果报告的附录包含在CD-ROM中。这些数据不仅对主位和焦点助词的研究有帮助，而且对日语口语的各种研究也有帮助。

This research revealed the difference between theme and focus particles in modem spoken Japanese and their counterparts in modern written Japanese, analyzing several particles such as "tte," "datte," "nanka," and zero-particles, which have seldom been researched.The results are shown in the six papers below contained in the research results report. The first two papers are about theme, the next three are about focusing, and the last one are about peripheral form of focusing.(1) "Tte" Presenting a Theme: An Aspect of Thematic Sentences with "tte" (Takahashi, Minako)(2) How a Theme Operates on Subject-predicate Structures and Adnominal Modification Structures: Describing Attributes in Spoken Japanese (Sawada, Hiroko)(3) The Function and Meaning of Focus Particle, "datte," in Spoken Japanese (Nakanishi, Kumiko)(4) Focus Particle, "nanka," to Express So-called Derogation (Nakanishi, Kumiko)(5) Presentative Focusing in Modem Japanese (Noda, Hisashi)(6) Usage of "toka" in Modern Japanese (Lee, Jangmi)In addition, we recorded and transcribed natural speech, and contained the 36 text data in a CD-ROM as an appendix of the research result report.
