Abstract

Metaphor generally exists in people’s life; it is the basis of people’s words and thoughts. Traditional theory regards metaphor as a figure of speech and a deviation of linguistic norm. After entering the new era, metaphor is regarded as not only a way of thinking, but also a cognitive mechanism. As a cognitive phenomenon, metaphor has extensive and profound influence on the human’s ways of thinking, artistic creation and language use. From 1990s, metaphor has become many domestic and foreign scholars’ study objects. Along with the prosperity of economy, economic discourses are widely concerned by linguists; they especially focus on metaphors of mood in these discourses. This thesis analyzes metaphors of mood in English economic discourses, carries out the research on the six detailed classifications of metaphors of mood and discusses the three functions of metaphors of mood. This analysis shows that the different language forms can achieve different communicative purposes and so as to improve people’s ability such as comprehension of language, language use, and communicative competence.
