| With the expediting process of urbanization in China, it is inevitable for ethnic population to immigrate into urban areas. Especially for the Korean nationality, large numbers of them move to big cities or abroad from their original inhabiting regions. And the immigration brings many differences on their ethnic language, such as the variation on the way of language using and language function, as well as the proceeding of speech accommodation. To get better with the new environment and accelerate the ethnic Korean's self-development, we should attach importance to language adaptation. We choose the Korean ethnic group in Beijing as the research sample because of the mass gathering of the ethnic Koreans as well as the Korean enterprises and Koreans; it is representative to carry out the research on the question of using and adapting language. And for reference purposes, this research also could produce an effect on other ethnic groups owing to the feature of highly educated, bilingual mastered, and increasingly population floated in Korean nationality.The paper contains five chapters. The preface mainly enunciates the purpose and importance of the topic. It also makes a list of the relevant references on language adaptation which come from both inside and outside China and clarifies the definition of the concept. The research of this paper is based on questionnaires and recordings of natural language, so this part also includes the method of choosing sample and conducting the research, as well as the evolution and current situation of Korean nationality in Beijing.According to the result of questionnaire's statistic analysis, chapter one elaborates the language using and adapting situation of university students, civil servants and white collar workers, as well as servers respectively on the basis of multitude category.The second chapter analyses the relevant factors that influence the adaptation of language. It takes age, gender, dialect, and living period as the variables, and then inspects the relationship between these variables and the language using and adapting situation.In chapter three, we make clear of the variation and adaptation cases of several elements in language which are vocabulary, appellations, and formulaic language. Based on natural language dialogues in the recordings, this part expounds the adapting situation of Korean ethnic group to the three elements which exist in speaking Korean and Chinese.The following chapter studies the language code-switching, which can be seen as one of the major strategies of language adaptation. It points out the different features of code-switching between bilingual ethnic Korean's city dwellings and their original region dwellings, and also the intensification of code-switching function in cities. We pick eight families in Beijing to observe the code-switching of children's language and reach a conclusion of the relationship between several factors like the way of education & language attitude and the children's first language acquisition by comparing the children's code-switching to their parents'. We could sum up the best way of learning language from the research.We could divided the context into language context and situational context, and the fifth part of the paper analyses the chief function of context in the language adaptation and the influences of context elements on language through several living communication examples. The conclusion summarizes and extends the important points and significance of the whole passage.This paper tries to research in a deep-going way and make a breakthrough in the following aspects:firstly, using several key variables as the middle axle to explore the decisive factors which closely relate to and have effect on the language adaptation apart from analyzing the basic situation by questionnaire research; Secondly, we try to use the text of natural language recordings and personal tracking as the research methods, and combine the research of language itself to excavate the proceeding, expression, and strategies of language adaptation to obtain useful results preliminarily. |
