In traditional linguistic theories,metaphor has been perceived as a kind of rhetorical device and one of the characteristic features of language,which is just an ornament and embellishment.Metaphors We Live By,co-authored by George Lakoff and Mark Johnson in 1980,changes people's opinions of metaphor.Metaphor is not only a figure of speech,but also a cognitive mode of thinking. Since then,people stepped into a whole new phase of understanding metaphor. In modern theories of metaphor,metaphor is pervasive in daily life.
