With the iteration and update of modern media and information technology，The carriers for the construction and dissemination of the national media bet365 bonus code louisiana are becoming more abundant，Redefining the concept and category of national media bet365 bonus code louisiana in this context has profound theoretical and practical significance。The unique symbolic logic of multimodal symbols gives them special meaning potential，Not only can enhance the dynamic and situational nature of bet365 bonus code louisiana construction，And can resort to different sensory channels to simulate perceptual experiences similar to those of related objects，Achieving a more intuitive and vivid media bet365 bonus code louisiana construction。

With the rapid development of information and media technology，Today’s society increasingly relies on multiple sensory channels and related experiences to construct discourse and obtain information，C. Jewitt calls it the “multimodal turn” in information exchange。With this turn，Non-verbal symbolic resources, as the main mediator in national bet365 bonus code louisiana construction, are increasingly used in discourse communication，Research related to national media bet365 bonus code louisiana has therefore become more diverse。Although this has to some extent promoted the “multimodal turn” in national bet365 bonus code louisiana research，However, most current research is still based on case analysis，However, the theoretical examination and thinking still need to be in-depth。

　　Redefine the concept of national media bet365 bonus code louisiana

Since there is no consistent standard for defining and classifying national bet365 bonus code louisiana，Therefore, it is necessary to first clarify the position of the national media bet365 bonus code louisiana in the pedigree of the national bet365 bonus code louisiana。Although national bet365 bonus code louisiana contains multiple categories，But according to Meng Xiangfei’s point of view，They can essentially be abstracted into three dimensions: entity bet365 bonus code louisiana，corresponds to objective reality；Media (virtual) bet365 bonus code louisiana，The corresponding media symbol is true；cognitive bet365 bonus code louisiana，Corresponding to subjective reality。Meng Xiangfei also further proposed，There is a close relationship between these three levels，On the one hand，National entity bet365 bonus code louisiana，That is, the objective truth about the country，Only by relying on specific media can it be represented and disseminated；On the other hand，Because the broad audience mainly accepts the reality constructed by mass media，Media bet365 bonus code louisiana plays a bridge role between physical bet365 bonus code louisiana and cognitive bet365 bonus code louisiana。

Due to the close relationship between the national media bet365 bonus code louisiana and the media，The academic community’s definition of its concept has been changing with the update of media understanding。in the country，Xu Xiaoge first defined national media bet365 bonus code louisiana as “the bet365 bonus code louisiana of a country formed in the international news flow or the bet365 bonus code louisiana of a country presented in the news and speech reports of other countries’ news media”。This definition has two limitations on the media bet365 bonus code louisiana: one is the bet365 bonus code louisiana presented by news reports，The second is that the source of the news report is other countries or international media。Such a limitation is questionable。First，According to the construction method，National bet365 bonus code louisiana can actually be divided into three types: 1，Self-shaping，That is, the bet365 bonus code louisiana of the country constructed by domestic media；Part 2，He Shao，That is, the media of other countries construct the bet365 bonus code louisiana of their country；Part 3，Intersubjective construction，That is, the national bet365 bonus code louisiana jointly constructed by the media of the country and the media of other countries。Later Zhang Yuqiang expanded its definition as "the output of a sovereign country through a specific medium under specific conditions after the information sent out by the system movement is reflected by the public"。With the further enrichment of mass media types and the continuous expansion of its communication radius，Advertising、movie、TV and even the Internet have long become intermediaries in the construction of national media images，It should also be included in the scope of concept definition。Based on this，This article defines the national media bet365 bonus code louisiana as the bet365 bonus code louisiana constructed and presented through language and multi-modal media discourse under specific conditions by the information sent out by a country in the process of systematic movement。

　　Looking at the characteristics of national media bet365 bonus code louisiana from the perspective of multi-modal discourse

From the perspective of multimodal discourse，Non-verbal symbols and verbal symbols are both meaning resources of discourse，Therefore, the bet365 bonus code louisiana construction of the two has certain comparability and similarity。However，The meaning potential and symbolic logic of non-verbal modalities are very different compared to words，Therefore, the national media images constructed by them also show considerable differences，Mainly reflected in the following three aspects。

　　bet365 bonus code louisiana representations are highly situational and dynamic.The media bet365 bonus code louisiana represented by multimodal symbols is also constructive compared with the bet365 bonus code louisiana represented by text symbols，But the former is more dynamic and situational。Constructivism believes，The national bet365 bonus code louisiana is not a pre-existing entity recorded by discourse，But as Chen Linlin said, "the cognitive model constructed in the minds of the audience after different discourses are played"。The constructive role of language on images is mainly reflected in the impact of the choice of language form on meaning，In turn affecting specific events、The bet365 bonus code louisiana recognition of characters and even countries in the minds of the audience。“Representation is an essential component in the process of generating and exchanging meaning among members of a culture，It does include language、The use of various signs and images that represent and express things”，Liu Danling’s view recognizes the important status of non-verbal symbols as resources for bet365 bonus code louisiana construction or representation of meaning。Zhao Xiufeng pointed out that multimodal media symbols have a similar constructive nature compared with words，However, the meaning potential and symbolic logic of non-verbal modality determine that its dynamic and situational nature are more prominent。Wang Xiaoping、Wang Jun mentioned that the dynamic nature comes from the symbolic logic of non-verbal modalities such as images and sounds，Images can imitate or reproduce the occurrence of specific scenes or specific events，The continuity characteristic of sound can also be used as a meaning potential to realize the construction of media bet365 bonus code louisiana，These can enhance the dynamics of the multi-media bet365 bonus code louisiana construction and presentation process。Situationality mainly relies on multiple perceptions appealed to by the cooperation of multiple modal symbols。Perceptual symbolism thinks，Cognition is the fusion and interweaving of perception and action，What multimedia representation realizes is a specific event or entity in a specific scene，The construction object of discourse realization is very specific，Highly simulated。In other words，What is ultimately presented in the media is an bet365 bonus code louisiana that only belongs to a specific situation。

　　Perceptual simulation has the narrative advantage of bet365 bonus code louisiana modality.The intuitive presentation and effects of national multi-modal media images are the communication advantages of non-verbal modal discourse。Meng Xiangfei believes that “the construction of discourse requires a certain symbolic medium to be produced”，The selection of discourse content deals with the problem of "what to say"，And "Symbolic media solves the problem of 'how to say'"。The mass media constructs the national media bet365 bonus code louisiana through symbols，Therefore, the choice of different symbols has a great impact on the media bet365 bonus code louisiana they construct。The advantage of text symbols lies in the standardization of meaning、Linearization and abstraction，But it cannot accurately reproduce the perceptual characteristics of different senses。Relatively speaking，Non-linguistic modalities such as images have a higher degree of restoration of sensory characteristics of various aspects of the object，Thus, it is possible to simulate specific objects in the form of perceptual simulation，Then producing perceptual experiences similar to direct observation of relevant objects on different sensory channels。The constituent elements of multimodal discourse are richer and more diverse than text，Color、size、Shape、Multimodal symbols with different attributes such as style corresponding to different perceptions，Therefore, the media bet365 bonus code louisiana it constructs is more intuitive。Since not everyone has the opportunity to directly participate in the experience，Multimodal symbols appeal to sensory similarities to simulate reality，The media bet365 bonus code louisiana it constructs has obvious narrative advantages as a communication medium with a relatively intuitive presentation method。

　　bet365 bonus code louisiana construction is symbolic meaning production.The country’s multi-modal media bet365 bonus code louisiana is not a mirror reflection of the country’s object bet365 bonus code louisiana，Symbolic bet365 bonus code louisiana construction is a complex process，Permeated with the ideology of the symbol maker。Reflection theory，The function of media symbols is to record or reflect objects that already exist in reality、Subject and meaning in events。According to Liu Danling’s thinking，National media bet365 bonus code louisiana is actually determined by national politics、Economy、Decided by objective reality in culture and other aspects，Essentially, it is an expression of its physical bet365 bonus code louisiana。Although there is perceptual similarity between images and objects represented by multimodal symbols，But according to Zhu Yongming’s point of view，Symbolic representation "is a constructed material carrier and meaningful object based on mental imagery and feelings"，Not exactly equivalent to the object it refers to。Construction theory thinks，The expression of meaning relies on media symbols that represent different concepts，Not an object。Follow this idea，The symbolic and metaphorical national media bet365 bonus code louisiana presented in media discourse is only a "mimetic" national bet365 bonus code louisiana。Therefore，Jiang Keyu thinks，It “derives from the object bet365 bonus code louisiana of the country，But it is not a ‘mirror reflection’ of the country’s object bet365 bonus code louisiana”。Use symbols to understand、Illuminating and characterizing specific objects that are often deliberately depicted，Or simplified，But essentially they are all based on the emphasis and choice of a certain perspective，Reflects the selection and activation of specific subjective ideas and value judgments。In other words，In addition to representing objects, media images constructed from multi-modal symbols，It also permeates the personal intentionality of the symbol maker。Construction theory further points out，Neither the bet365 bonus code louisiana object itself nor the maker of the symbol can alone determine the meaning of an utterance，The audience uses discourse as a medium to contact reality and construct meaning，This process relies on a symbolic representation system。Liu Danling proposed that these symbols themselves contain a large amount of cultural preset information，The application and expression of this conventional code meaning system will directly lead to the legalization of its inherent ideology。Basic principles of symbols，According to Zhu Yongming’s opinion，It is "to use one thing to represent or symbolize another thing"，Therefore，Symbolic representation does not represent the objective entity itself，It is a specific meaning and value based on a specific perspective。According to this point of view，The construction process of national media bet365 bonus code louisiana is a process in which ideologically mediated representation codes produce meaning，The realization of symbolic meaning requires the selection of appropriate symbolic resources to realize the interests of the symbol maker。But，The influence of ideology on the use of codes is not unlimited，Code resources must be adjusted within the cultural traditions of a specific context、Shaping and Construction，Make it consistent with the interests of the symbol maker and compatible with the specific context。

With the iteration and update of modern media and information technology，The carriers for the construction and dissemination of the national media bet365 bonus code louisiana are becoming more abundant，Redefining the concept and category of national media bet365 bonus code louisiana in this context has profound theoretical and practical significance。The unique symbolic logic of multimodal symbols gives them special meaning potential，Not only can enhance the dynamic and situational nature of bet365 bonus code louisiana construction，And can resort to different sensory channels to simulate perceptual experiences similar to those of related objects，Achieving a more intuitive and vivid media bet365 bonus code louisiana construction。Also，Symbols are not only a medium for information exchange，It is also an important carrier of ideologies such as values ​​and positions。Therefore，How to make good use of non-verbal symbolic resources with narrative advantages to construct and spread a true and positive media bet365 bonus code louisiana of China，The issue of “China’s voice” in the setting of international public opinion issues is also an issue that researchers should focus on。
