On the Vibration Mode of Semantic Wave of Ideational Grammatical Metaphor
Ideational grammatical metaphor(IGM),as a meaning strategy,plays an important role in the construction of human scientific knowledge.Semantic wave theory(SWT)aims to provide an objective and scientific interpretation of how knowledge is constructed through gradual accumulation.This paper,based on SWT,introduces the classification and vibration mode of semantic waves,and then elucidates how semantic waves of IGM realizes the cumulative growth of knowledge in real discourse through the cyclical pattern of"simple harmonic vibration-damped vibration-forced vibration-simple harmonic vibration...".This study will provide some enlightenment for further exploration of the process of how IGM participates in the construction of knowledge as well as a new perspective for the interdisciplinary study on IGM.
