摘要

俚语是语言的重要组成部分,也是一种特别的语言形式。一般来讲，俚语作为一种非正式、非标准的英语，来自于人们的日常生活。而在日常交流中，使用隐喻的频率很高，尤其是在美国俚语中。本文将从认知语言学的角度，对美国俚语中的隐喻及其社会语用功能进行分析，社会语用功能从寻求认同感，增加亲昵感，表明社会地位和用作讽刺挖苦四个方面进行讨论。

Abstract

Slang is an important part of language, and also it is a special form of language. In general, American slang is informal and non-standard English, which comes from people’s daily life.  In daily communication, metaphor is commonly used, especially in American slang. This thesis will analyze metaphor and its social pragmatic functions in American slang from the perspective of cognitive linguistics. The four social functions will be discussed: seeking identity, increasing intimacy, indicating the status and being used for sarcasm. 

Key words: American slang; metaphor; Cognitive Linguistics; social pragmatic functions
