Once regarded as two isolated concepts by many scholars,language and emotion were usually studied within the fields of philosophy,psychology and linguistics respectively. Neuroscience and artificial intelligence,in recent years,have developed very fast but at the same time encountered the unsurpassable barriers,i. e.,language and emotion. As a consequence,an increasing attention has been shifted to the relationship between language and emotion. This study is intended to present a sketch of the studies of language and emotion so as to build a view of the co-constructing relationship between language and emotion,which may provide clues and perspectives for future studies in this area.
