The Politeness Principles of Self -Lisa and the Polish Strategy theory of Brown and Lensen is introduced to Japan，Polite phenomenon in communicative speech behavior has been expanded in Japan，Multi -dimensional angle，Full results。Related theories were first passed to Japan，Many Japanese scholars simply equate polite language with honor expression，Even the principle of politeness is even translated into "Dear Principles"，As a result, it caused a lot of misunderstandings。Therefore, Ruodian Dozi thinks，"Police" should not be simply equivalent to the expression of respect，The "politeness" behavior in Japanese language should be called "worrying performance"。"Fantastic performance" refers to the communication between the two parties in order to maintain a good interpersonal relationship、Consider the relationship between the two parties and position、Take care of the mood of the other party、The language performance implemented by the other party's feelings。But the exact Chinese translation of the word "good performance" in Japanese，No conclusion in the domestic academic community，The translation of comparative recognition includes "decent expression" and "take care of expression"。The author believes that the translation meaning of "decent expression" is more appropriate，Therefore, this article uses "decent expression"。

Scholars between China and Japan conducted related research from different perspectives。These research perspectives can be summarized as the following aspects。

First, analyze the front statement from the perspective of grammar、Sentence Ending Quality and adverbing expressions，Try to establish a decent expression of bet365 live casino games the basic data corpus。The three thousand generations of Shouwu defined the basic elements of decent expression from the perspective of grammar。Peng Fei explored the function and characteristics of Japanese -decent expression from the perspective of the comparison of the sentence composition and Chinese Japanese。Yamana Masakuki and other common misuse instances，Discussion request、Against the useful sentences and adverbing practical applications related to an apology and other occasions。With the deepening of research，2015，Yamanaka Masako has further updated the definition of decent expression，He believes that taking care of the other party's mood、The usual manifestation of the use of the other party's feelings and implementation is "Expressing"。When people are expressed in use，I often use some usual performance。Such statements like this、The adverbials should be included in the body expression in the basic data corpus。

Second is in the perspective of the analogy，Direct use of polite strategy theory、Discourse polite theory, etc. Investigating the use of decent expressions in different occasions。Scholars who use this method for decent expression research think，Polite language in Western theory can be equivalent to the decent expression of Japanese。Zhao Huamin believes that "politeness" research should focus on the effect of speaking，Not sticking to language form，and define "politeness" as establishing、Maintaining harmonious interpersonal relationships，Words and behaviors that have been obtained according to the context，and point out that the focus of the Japanese academic community's research on "politeness" has been transferred to how to establish a harmonious interpersonal relationship。Yuzu Mei Zhenmei believes that it should pay attention to whether it can make the other person feel the substantial speech bet365 best casino games effect。She emphasizes that it should not be limited to a single sentence，and should be examined from the complete discourse level，So perform dynamics、Comprehensive analysis。At the same time，She also created discourse polite theory on the basis of polite strategy theory，and proposed a "basic state" (typical mode of the overall expansion)、"Concepts of Speaking" (the appearance of the body and the simplifiedness) and other concepts。No Nu new comparison of the expression of China and Japan from the perspective of polite strategies and discourse politeness，The commonality and characteristics of the two languages ​​were revealed by analyzing the natural sessional library。

Third, from social linguistics、History Linguistics、Analysis of cultural linguistics and other angles、Definition of decent expression，and many beneficial exploration。Noda Shangshi, etc. During research, I found it，Japanese decent expression has been taken as early as the safe period，and the historical changes of the decent expression and the historical changes of the usage meticulous combing and analysis。According to the Japanese National Mandarin Research Institute's 2006 field inspection report "The" Endless "in the Words"，Modern Japanese decent expressions、Rich content，and have a significant regional difference、age difference、Gender difference。Sanzhai and Zizi through session analysis，Discuss how people are based on different interpersonal relationships、Appropriate use of expression on the occasion，and carefully examined the different similarity expressed by the use of electronic media such as mobile phones in modern society。

Fourth is the cross -cultural understanding expressed in Japanese and Japanese education.。In the process of Japanese teaching in the past，Teachers and learners often pay more attention to grammar、Vocabulary bet365 Play online games and other grammar knowledge，Introduction to the introduction of related concepts of Japanese decent expressions，Therefore, even if the learner has a good grammar knowledge，But it is difficult to speak in actual speech communication，Perform effective communication。So，Destroyer expression is increasingly valued by the Japanese education community。Ji Ye Yiko, etc. as a Japanese teacher for international students，In communication with foreign Japanese learners, there are often poor communication due to improper use of physical expression、Uncomfortable situation。So，On the basis of Licer's "politeness principle"，From "interest、Live、Enhui、Trouble "," Decision and Will "," Private Field "and" Self -Positioning ":、Basic principles expressed in decent，I hope foreign Japanese learners can learn to master these principles，Avoid entering the "Thunder Area"。Fujiwara Anzo, etc. integrated the above basic principles，Three principles of decent expression，"Avoid infringing the other party's private field", "avoid placing themselves in the same position as the obedient", "must express your benefit and the burden brought to the other party，Avoid referring to the burden you have affected and the benefit of the other party "，and analyze common misuse example sentences，Further strengthen the appropriate use of the decent expression。Three thousand generations in the house thinking，Part of the content and example sentences of Chinese Japanese textbooks exist in explanation grammar that is correct but not in line with the principles of decent expression。Zheng Rongai is centered on the adverbs "けど" and "ちょっと"，After investigating the Japanese textbooks used by foreign students in foreign students, I found it，From the perspective of the decent expression, the syntax explanation of the two of them is not enough。The theory bet365 best casino games of politeness without breeding defines the "basic state" of the Han and Japanese request behavior。He thinks，Can't correctly grasp the biggest problem of Japanese learners，And the most commonly used polite strategy of Chinese students is the avoided by Japanese mother tongue。So，He proposed to introduce the concepts of polite strategy theory and basic state in Japanese teaching。

　Overview of Japanese Linguistics Research

To sum up，Rich research perspective on decent expression，Fire results。Research perspective of decently expressed expression，We can initially understand the development of Japanese linguistics research。

First，Empirical investigation research is enduring。Japanese linguistics always pays attention to empirical investigation research，Japanese scholars tend to use real corpus，Through field inspection、Questionnaire survey、Face -to -face interviews for research，Now I still use the corpus and other tools，Further explore more scientific and reasonable answers。2，The emergence of new technologies provides a new method。Development of science and technology is new to each other，Big Data、Database、The concepts of corpus libraries have increasingly attracted the attention of scholars。Research Research Research and the relationship between the corpus is getting closer，The corpus provides a strong support for the study of Japanese -decent expression。The research and construction of a decent expression of language in the basic work has naturally become one of the key topics of Japanese language researchers。third，Theoretical research has strengthened and innovated。No longer obey the theory of Western，but is solid、Merit information for comprehensive and meticulous information、Investigation and analysis。Some scholars based on Western theory，Create the theory of politeness and polite the theory and widely apply it。At bet365 live casino games the same time，Many scholars also use Japan to lead the world's social linguistics、Cultural Linguistics、Dialects and other theories，Multi -angle、Study on the expressed expression of decentralized expressions。fourth，Application is worth highlighting。Researchers not only pay attention to the language itself，And began to use the research results into Japanese talent training，Efforts to improve the application value of research。Fifth，Research fields continue to expand。Research content gradually gradually to comparative research from traditional ontology research、Expansion of cross -cultural exchange。The trend of mutual penetration in the research field is becoming increasingly obvious。In addition to consolidated、Cultural Anthropology、Cross -cultural communication，Dialect、Psychology、Compared with linguistics、Symbolology、Corgal Library Linguistics and many other fields have also been further integrated and participated。Sixth，Data analysis is more objective and effective。Reasonable introduction of statistical methods，More objective、Effectively analyze the data，Data analysis is becoming more and more scientific specification。Research conclusions are also more reliable，More convincing。

I think，Related research on the expressed in the future still needs to make greater efforts in the following three aspects。

First，Strengthen theoretical support。Further improve the theoretical of research，Strengthen the summary of language laws，Avoid it to stop。2，Follow the academic frontier。Follow the latest progress of linguistics research，Fully draw on the research results of other languages，Expansion research vision，Rich research method。third，Improve the application value of research results。Research should be committed to solving actual problems，Zizheng Bet365 lotto review Qimin，Research should be committed to solving actual problems，Improve the cultural literacy of learners and cross -cultural communication abilities。
