Swiss linguist Jef Verschuren proposed Linguistic Adaptation Theory, according to which pragmatics is an overview of language use behavior from a cognitive, social and cultural perspective. According to Verschuren's adaptation theory, in the process of communication, the reason why language users can make discourse choices suitable for the context according to their own consciousness is mainly because language has variability, coherence and adaptability (adaptability). Among them, variability lays the foundation for the dynamic choice of language in communication; negotiability means that the choice of language can be dynamically negotiated in a very flexible way; adaptability means that language users can adapt to the purpose of communication in a specific context , choosing from the available languages, with flexibility in the cognitive awareness of choice. Language adaptation theory emphasizes that language selection and adaptation must be adapted to the communicative environment, and translation is the process of using language in cross-cultural communication. Therefore, adaptation theory has strict guidelines for translation research and practice. Considering that the translation process is a process of converting two language codes in different contexts, it must include the variability, consistency and adaptability of the language, so translation should be planned from four aspects of cultural context adaptation. The adaptation of language structure, the dynamics of adaptation, and the role of consciousness in the translation process are also the four dimensions of adaptation theory to describe and explain language use. According to the theory of adaptation, translation is a dynamic selection and adaptation process of trans-context code-switching that is continuously carried out by the translator under the influence of psychological awareness. Variability and consistency of language provide the basis for corpus translatability, while adaptability provides translation with psychologically conscious adaptation and dynamic selection of context and language structure. It can be seen that only when the translation conforms to the specific context can we ensure the success of cross-cultural communication and realize the social and cultural value of translation. Adaptation theory provides theoretical guidance for translation from the perspectives of semantic selection, discourse adjustment, pragmatic reasoning, and cognitive psychological adaptation. and reproduced the content of the original information. <br>In a word, the role of adaptation theory in translation is mainly manifested in: under the influence of cognitive psychological factors, limitations of social and cultural background and other factors, translators dynamically and flexibly choose the form of translation. Through psychological awareness, highlight the language expression that conforms to the reader's cognitive context, and actively re-create the original text to ensure the translation effect and achieve successful communication.

Swiss linguist Jef Verschuren put forward the linguistic adaptation theory. According to this theory, pragmatics is an overview of language use behavior from the perspective of cognition, society and culture.

Language adaptation theory emphasizes that the choice and adaptation of language must adapt to the communicative environment, and translation is the process of using language in the process of cross-cultural communication. Therefore, adaptation theory has strict guidance for translation research and practice. Considering that the translation process is a process of the transformation of two language codes in different contexts, which must include language variability, consistency and adaptability, translation should be planned from four aspects of cultural context adaptation. The adaptation of language structure, the dynamics of adaptation and the role of consciousness in the process of translation are also the four dimensions of adaptation theory to describe and explain language use. According to adaptation theory, translation is a dynamic selection and adaptation process of cross contextual code switching under the influence of psychological consciousness. The variability and consistency of language provide the basis for the translatability of corpus, while adaptability provides psychological conscious adaptation and dynamic selection of context and language structure for translation.

Adaptation theory provides theoretical guidance for translation from the perspectives of semantic choice, discourse adjustment, pragmatic reasoning and cognitive psychological adaptation. And reprinted the information content of the original text.<br>In short, the role of adaptation theory in translation is mainly reflected in the translator's dynamic and flexible choice of the form of translation under the influence of cognitive psychological factors and the limitations of social and cultural background.

Swiss linguist Jef Verschuren put forward the Linguistic Adaptation Theory. According to this theory, pragmatics is an overview of language use behavior from the cognitive, social and cultural perspectives. According to Verschuren's adaptation theory, in the process of communication, the reason why language users can make discourse choices suitable for context according to their own consciousness is mainly because language has variability, coherence and adaptability (adaptability).

Language adaptation theory emphasizes that language selection and adaptation must be adapted to the communicative environment, while translation is the process of using language in cross-cultural communication, so adaptation theory has strict guidance for translation research and practice. Considering that the translation process is a process of code conversion between two languages in different contexts, which inevitably includes language variability, consistency and adaptability, translation should be planned from four aspects: cultural context adaptation. The adaptation of language structure, the dynamics of adaptation and the role of consciousness in the process of translation are also four dimensions of the adaptation theory to describe and explain the use of language. According to adaptation theory, translation is a dynamic selection and adaptation process of cross-context code-switching under the influence of psychological consciousness. The variability and consistency of language provide the basis for the translatability of corpus, while adaptability provides psychological self-conscious adaptation and dynamic choice of context and language structure for translation. It can be seen that the success of cross-cultural communication can be guaranteed and the social and cultural value of translation can be realized only if translation meets the specific context. Adaptation theory provides theoretical guidance for translation from the perspectives of semantic choice, text adjustment, pragmatic inference and cognitive psychological adaptation. And reproduced the information content of the original text. In a word, the function of adaptation theory in translation is mainly manifested in the following aspects: under the influence of cognitive psychological factors, social and cultural background limitations and other factors, the translator dynamically and flexibly chooses the form of the translation. Through psychological awareness, we can highlight the language expression that accords with the reader's cognitive context, and actively re-create the original text to ensure the translation effect and achieve successful communication.
