The first level of literary text is the language level, which is the appearance of the text composed of language materials, that is, a series of linear combinations of words and sentences. The language layer includes phonetic and semantic parts. The language layer of literary texts has relatively independent aesthetic value. Language gives readers aesthetic feelings through "signifiers", that is, its own characteristics; this is particularly prominent in poetic language. For literary texts, especially poetry, voice has independent status and value. The semantic expression of literary texts is based on the requirements of rich connotation, comprehensive information and personalized experience. It often resorts to various rhetorical means and deliberately violates existing language conventions in order to make the expressive behavior an artistic creation with aesthetic value. . Literary language therefore has the characteristics of being ambiguous and implicit. This semantic feature of literary language can be grasped from the special context of the literary text. The prerequisite for establishing the context of a literary text is often separated from the daily context. This feature provides conditions for readers' creative participation and gives readers a wider space for imagination.
The second level of literary text structure is the phenomenal level. The presence or absence of the phenomenal layer is one of the bases for distinguishing literary texts from non-literary texts. Literary texts are mainly composed of image systems. In the composition of literary texts, the phenomenon layer occupies a core position. It is both the referent of the language layer and the carrier of the connotation layer. This characteristic of the phenomenal level has also become an important basis for judging the aesthetic value of literary texts: literary texts must not only have vivid and touching images or imagery, but this image system should also have rich and profound aesthetic connotations. Specifically, in lyrical literary texts, the phenomenal layer is mainly embodied in coherent and flowing emotional counterparts; in narrative literary texts, the phenomenal layer is embodied in acting characters, developing plots, and changing environments. The image system that constitutes the phenomenal layer of a narrative text is also a product of fiction and imagination, and contains a certain meaning just like the phenomenal layer of a lyrical text.
The connotation layer is the "implicative meaning" of literary texts. The value of a literary text ultimately depends on the aesthetic meaning it contains and displays. The implication layer is an indispensable component in the composition of literary texts; whether the implication is rich and deep directly affects the aesthetic value of the literary text; the implication is the soul of the literary text. The implication of a literary text cannot exist independently from the literary image, that is, the phenomenal level of the text. The relationship between image and implication is a relationship of integration and unity. The connotation of a literary text is the meaning contained in the textual phenomenon level, which is implicit and polysemous. Literary text is a deep unity composed of language layer, phenomenon layer and connotation layer. The upper level is the formal manifestation of the lower level, while the lower level provides the upper level with the content and content of existence. in accordance with. Among them, the phenomenal layer plays the role of intermediary connection. The literary image reflects the dialectical unity of the content and form of the literary text in its dual relationship with literary language and literary connotation.
