A Study On The Dynamic Transformation Of English Core Sentence From Event-domain Cognitive Model

Core sentence is the most important sentence type in English, and other sentences are transformed from it. However complicated a sentence is, it can be divided into core sentences. Therefore, it is of vital importance to research the transformation process and semantic variation of the core sentence. In this paper, the core sentence is divided into dynamic sentence and static sentence, and the dynamic sentence indicates the dynamic developmental process of the event while the static sentence emphasizes the relatively stable state. Between the dynamic sentence and static sentence, there exists have-sentence as well as passive sentence; the former has stronger dynamic sense while the latter highlights relative static sense. In the end, the paper further discusses the transformation process of complex object sentence.Semantic comprehension is a conceptualized process, and conceptualization consists of two sections, which are semantic content and construal ability. Semantic content is provided by cognitive domain, and the meaning that language conveys is the construal of cognitive domain. Construal refers to the cognitive ability of human, and impacts of different cognitive methods on the same event can lead to different dynamic changes of language expression and meaning. This paper, based on the Event-domain cognitive model presented by Wang Yin, holds the view that each English sentence describes the state of an event, and an event generally contains agent, patient, setting and other elements. Thus, the analysis of each sentence is developed according to the agent, patient and setting. In addition, analysis from the perspective of event domain can cover both dynamic and static dimensionality, as a result, this research can effectively make up for the past inadequate analysis and construal of the static sentence. A static event generally includes participant and static verbs which represent the relatively static relation between participants; the transitivity of static verbs is lower than the transitive verbs in dynamic sentence. There is no obvious power transmission and reception between participants.According to the semantic construal of different core sentences and their transformational sentences, the findings of this paper are as follows:Firstly, representation of an event could be divided into a continuum between static and dynamic state. An event sometimes presents dynamically while sometimes statically. With the development of human cognition, dynamic and static states can be transformed into one another, which eventually lead to various transformations of dynamic sentence and static sentence in language to meet various communicating purposes of human.Secondly, the transformation of English core sentence is to meet human need in highlighting different angles according to different scenes of the same event domain. The speaker can adjust his own language form based on his main communicating purpose to show relevant scene. On the contrary, the language receiver can extract the communicating purpose of the speaker according to the language form he gets and reproduce the scene that is presented by the speaker.According to the analyses above, we can come to the conclusion that:In theory, this paper analyses the relationship between communicative purpose and sentence selection. In order to achieve different communicative purposes, people tend to select different sentence forms to show relevant scenes. Language form determines its meaning and different expressions of the meaning are to highlight different communicative purposes. Meanwhile, context imposes restrictions on sentence transformation. The speaker chooses appropriate sentence structure to express according to the concrete context.
