Translation is a complicated mental process,involving such factors as culture,cognition,emotion and consciousness.To explore the translation process from the angle of mental models is an attempt to apply findings of cognitive science to the research of translation.The delivery of meaning in the process of translation is intimately associated with the selective processing activities of the mental models,which contribute to or limit,to a great extent,translators' comprehension of the linguistic forms,representation of meanings in the original work,and hence their stylistic choices and expressions of forms and meanings in the targets language.
