In the theoretical aspect, this study can expand the scope of pragmatic identity construction. And the study of identity from the perspective of Adaptation Theory can enrich researches on identity construction in different contexts. In addition, this study can further help people understand how pragmatic identity construction promotes the realization of communicative purposes in a communicative context. Additionally, investigating the identity construction is conducive to a more comprehensive understanding of the characteristics of such verbal communication, which can enrich the relevant researches of pragmatics and identity construction. At the same time, it also provides a new perspective for studies of speaker’s identity construction. 

Chapter Two  Literature Review

2.1 Previous Studies on Identity

The word “identity” originates from the Latin language, which means personality and identification (Phinney, 1990). Identity is an important concept in sociolinguistics, which mainly refers to a social phenomenon, a social symbol constructed by people, and the use of human language in society. In the field of sociology, identity is defined as the status of social individuals, or the groups in a certain social relationship. Peter and Nick (1988) propose that identity is the expression of a person’s ideology. And Antaki and Widdicombe (1998) divide identity into three categories under social relations, namely, display, attribution and membership. 

As far as the term “identity” is concerned, scholars have different definitions of identity. Stryker (2002) proposes that identity is the role a person plays in society, which can be static or dynamic. American communication scientist Tracy (2002) puts forward two different concepts from the perspective of communication, namely interactive identity and relational identity. According to Tracy (2002), interactive identity refers to the mutually related identities presented by a person and others in a communicative context. Relational identity refers to the relationship between people and other members of society when they engage in dialogues with other members of society in a specific context. Bucholtz and Hall (2005) give identity a new definition and point out that identity is the social orientation of self and others. They try to study identity in an open and dynamic framework. And also, they study identity and interaction from the perspective of socio-cultural language. They put forward an analytical framework to study identity construction, which can maintain and display in language interaction from multiple perspectives. The framework mainly includes five principles, which emphasize the dynamics of identity and the constructiveness of discourse, and these five principles can be used to analyze the process of identity construction. 

2.2 Previous Studies on Identity Construction

In the category of social constructivism, identity is a kind of communication resource, and the relationship between language and identity is very close. It can be presented through various linguistic or non-linguistic means and strategies in a specific context. So speakers construct and transform identity according to different contexts. 

The construction of social identity is flexible and changes with the context. In social本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
