1. Introduction

This article introduces the definition, structure, and research history of implicit sentences, pointing out the early view that implicit sentences are the beginning and end of existential sentences, as well as the shift in later research to view the two as parallel relationships. At the same time, it points out the limitations of existing research, which mainly focuses on a single language and lacks cross linguistic comparative studies. This article aims to explore the coupling law between the descriptive structure and focusing device of English and Chinese implicit sentences from the perspective of prototype model resemblance, in order to provide new perspectives and research methods for the resemblance law of second language implicit constructions.

2. Literature review

Reviewing the development process of research on implicit sentences both domestically and internationally, it is pointed out that domestic research has shifted from basic concepts and structural analysis to cognitive interpretation. However, there is a lack of in-depth interpretation of the semantic causes and cognitive motivations of second language implicit constructions. Foreign research focuses on psychological motivations and structural features, but does not involve the origin of implicit sentence description structures or the formation of focal devices. Existing research mostly analyzes from a single perspective, lacking multidimensional arguments on the essential attributes of implicit sentences and their deep relationship with cognition. This article aims to compare and analyze the basic structures, causes, and resemblance characteristics of English and Chinese implicit sentences from the perspective of prototype model resemblance.

3. Definition and Causes of English Chinese Implicit Structures

An in-depth analysis was conducted on the composition and causes of English Chinese implicit sentences, pointing out that they are composed of place phrases, verbs, and implicit entity nouns, and have narrative and descriptive structures. The framework of English Chinese implicit constructions is shown in Figure 1, revealing the similarity between Chinese implicit sentences and English implicit sentences. We discussed the impact of the topic meaning of place phrases and the transfer of sentence components on narrative structure, as well as how implicit sentences focus on information through linear word order and descriptive structure. Emphasis is placed on the function of English Chinese implicit sentences as a focusing device, which facilitates the transformation of new information into information focus through natural arrangement.

4. Theoretical framework

Based on the prototype model theory, the relationship between language and the objective world is explored, and it is believed that language is a model that reflects the real world. As the simulation subject, humans create language models of different styles according to their needs. There are common foundations and differences between prototypes and models, which are consistent with the resemblance of linguistic symbols. The similarity of language models is reflected in the grammatical meanings of syntactic rules and constructions, which are related to people's daily life experiences and cognitive conceptual structures. The comparative analysis of English and Chinese implicit sentences reveals the similarity relationship between language structure and cognitive conceptual structure from three dimensions: distance, order, and marker similarity. By constructing a language prototype model similarity analysis framework and combining it with cognitive construction grammar, the aim is to explore in depth the syntactic components, word order, and sentence structure characteristics of English and Chinese implicit sentences, providing a new perspective for understanding the relationship between language and thinking.

5. Comparison of Iconicity between English and Chinese Implicit Sentences

In depth exploration of the comparative analysis of English and Chinese implicit sentences in terms of iconicity, mainly from three levels: distance, order, and marking. In terms of distance similarity, both English and Chinese languages exhibit a positive correlation between the distance between components and the distance between conceptual relationships, which is reflected through the principles of "centering the connecting item" and "approaching the core". For example, prepositional phrases in English and particles in Chinese serve as linking terms, bringing the distance between subordinate languages closer and enhancing semantic coherence. At the same time, English and Chinese implicit sentences also follow the principle of distance resemblance when the actual word is used as the connecting item, such as prepositional phrases in English and topic structures in Chinese.

6. Conclusion

From the perspective of prototype model analogy theory, this paper compares and analyzes the descriptive structure and focusing device of English and Chinese implicit sentences. There is not much difference in distance similarity between the two languages, with similar principles of centering and core proximity for the linking item. However, the position of the linking item has a significant impact on sentence meaning. In terms of sequential similarity, English implicit sentences have flexible phrase positions, while Chinese implicit sentences do not conform to the conventional principle of sequential similarity. In terms of similarity, English emphasizes subject verb agreement, while Chinese emphasizes word order, sentence structure, and dangling topics. The article points out that further research is needed on the resemblance characteristics of implicit verbs and the hierarchical attributes of implicit constructions. Integrating internal and external hierarchical structures with existential sentences, topic sentences, and other constructions can help deepen the understanding of implicit constructions in English and Chinese.
