　　Prospective Reflection

Elastic identity theory is widely used in the above -mentioned multi -language service areas，It shows the strong vitality and actual application value of the theory。But it is worth noting that，So far，Application field of verbal identity theory is still in the traditional face -to -face language service practice，There are little research on virtual interaction based on social media in the Internet。Current，Social media has become an indispensable part of people's lives，between people、Online virtual social behavior between institutions and the public is even more frequent than directly communicating directly from the opposite side of the line。Under such a social interactive context that cross parallel in parallel in such a mimic environment and the real environment，Future research should focus on how to expand language research from the field of traditional language services to the field of new media language services。For example，You can target government affairs Weibo、WeChat、Online Medical Consultation、Internet crowdfunding and other social media language service activities in the language service activity selection、Research on discourse construction and communication effect，Pay attention to how to serve the trust and construction between new media users、Interpersonal relationship management and institutional image management。

Active identity research in social media language service activities，Researchers want to Weibo、Social media such as WeChat and other Bet365 lotto review social media have sufficient recognition: they are not simple "online text"，but based on hybrid media，Interaction between the communicators supported by technology。So，Researchers should pay attention to unique in social media interaction、Form of words of self -containing，Including video、Picture、Technical symbol resources such as emoticon symbols and topic labels。At the same time，Researchers must not only pay attention to the discourse strategy of network identity construction，Pay more attention to the dynamic cause behind the identity construction of online language service participants，and the social impact that may have occurred。For this，You can consider using discourse analysis、Online interview、Internet Folk Customs Survey、Online questionnaire survey and other multiple research methods。Of course，You can also use computer technology and corpus tools to conduct quantitative research，to make up for the insisting subjectivity of traditional qualitative research。

Current，The main contradictions of our society are contradictions between the people's growing good life needs and inadequate development。"The people's growing good life needs"，also includes harmony、Health、The needs of colorful social language life。This depends on the continuous enhancement of social language service consciousness，and the continuous improvement of language service capabilities。Guide medical treatment with identity theory with language、Education and administrative law enforcement language service practice，Can effectively improve the discourse ability of language service subjects，Avoid the service language caused by improper status、Poor communication、Disgustible and disagreement and other issues。I believe that with the experience of the practice of language service in my country、bet365 live casino games Language service research is continuously deepened，Language service theory and empirical research based on verbal identity will become increasingly mature and meticulous，Therefore, in order to effectively promote the development of my country's local language service industry and the improvement of language service quality, it plays a positive role。
