1. Introduction

This article introduces the concept of trace adverbs in both English and Chinese languages, and explores the syntactic properties and functions of "a bit" in English and "a little bit" in Chinese. The article analyzes whether "a little" is a word, its retained verb syntactic properties, and the co-occurrence of adjective reduplication with "a little". At the same time, the overlapping structure of adjectives was discussed to represent state description rather than degree change, as well as the viewpoint that a bit and "somewhat" involve measurement categories.

2. Syntax of Adjectives

Deeply explored the syntactic structure of English and Chinese adjective phrases, analyzed the composition and functional categories of adjective phrases. Bresnan proposed that English adjective phrases use quantitative phrases as indicators, quantitative categories as the core, and finite phrases as indicators. Abney refers to the limited category as the measurement category, while the quantification category is usually omitted and can be implemented as much, little, enough, etc. in specific contexts. The suffix jump rule has been replaced by core shift, but core shift must comply with core shift restrictions. Corver put forward the functional core analysis method. Deg and Q are the functional cores of extended adjectives. Deg has affix characteristics, which can attract its sisters to shift the core. The displacement of Deg is constrained by structural preservation requirements, which are more stringent than the left branch constraint. The displacement test shows that only the structure can be displaced as a whole. Deg and Q can be chosen as metric arguments, located at the indicative position of DegP. The Chinese adjective syntax is roughly the same as English, and can assign consistent structures, but there is no Q in Chinese. There is no need for mandatory phonetic implementation of Chinese predicate categories, and adjectives can be elevated to the Pr position. The structure of English Chinese adjective phrases can be expanded, such as setting measurement categories and hierarchical categories.

3. The syntactic position of trace adverbs

In depth exploration of the syntactic position and function of trace degree adverbs in both English and Chinese languages. In English, a bit is used as a metric argument, located at the indicative position of DegP, introduced by the Deg category. The structure of "a little bit A" in Chinese is similar to a bit, where "you" is the phonetic implementation of Pr, similar to the verb "be", and "(i) dian" serves as a metric argument, corresponding to a bit. The article analyzes the use of 'a bit' and '(a) dot' in different sentence structures through specific examples, pointing out that they can coexist with 'too' and '- er', but 'a dot' cannot be used as an adverb in comparative sentences. In addition, the chapter also discusses the influence of the number of syllables in adjectives on their structure, as well as the positive and negative polarity of A in "a little A". The article further points out that a bit and "(a) dian" as noun components have polarity sensitive meanings, while "you" as the implementation of the predicate category Pr endows "you dian" with verb like characteristics. Finally, the chapter summarizes the role of a bit and "(one) dot" as metric arguments in syntax, as well as their relationship with Deg and Pr.

4. The co-occurrence of the measurement category of introducing trace level adverbs with other measurement categories

Explored the co-occurrence of trace adverbs in English and Chinese adjectives and phrases. Zhu Dexi proposed that state adjectives should not be modified by the word 'very' because adjectives overlap and already contain meaning. However, 'somewhat' can modify the adjective reduplication, indicating that it is not a degree adverb. Xiong Zhongru analyzed from the perspective of generative grammar and believed that Deg has multiple forms, including affixes and zero forms, and overlapping adjectives are formed by the fusion of Deg and RED. Zhu Dexi further pointed out that overlapping adjectives have auxiliary parts of speech, but their function changes after adding "de". Li Difei and Cheng Gong questioned the conflict between Deg and overlapping affixes, but overlooked that the same category can coexist under certain conditions. Huang et al. proposed that the temporal aspect category can coexist, while Rizzi proposed that the topic category can coexist. This article proposes allowing the co-occurrence of two Degs and reanalyzes the structure of "somewhat" and adjective overlap. It suggests that the measurement category can co occur with other measurement categories, such as "slightly tense", indicating that there can be multiple measurement categories that extend adjectives in a sentence. This is similar to the 'a bit' in English, where functional categories with different features can coexist, but 'very' does not coexist with state adjectives because it carries the same information.

5. Co occurrence of trace adverbs and adjectives

Explored in depth the co-occurrence phenomenon of trace adverbs and adjectives. Rao Jiting distinguishes "very" into degree adverbs and multi quantity adverbs, but this article believes that both types of "very" belong to the category of measurement. The trace adverb 'a bit' cannot coexist with contexts that represent a large quantity, as feature matching is required. Relative adjectives such as "big, small, salty, and light" can coexist with "a bit", but negative forms cannot. Absolute adjectives such as "clean, dirty, straight, curved" have inherent measurement, and their positive form is opposite to the co-occurrence of "somewhat" and negative form. The modification of absolute adjectives in English also has context dependence. When the predicate category Pr is implemented as "there", Deg has trace features and can choose relative adjectives or absolute adjectives with the minimum standard. Positive adjectives can coexist with 'somewhat' and may not necessarily carry unexpected or contrary meanings. A bit can also coexist with positive adjectives in specific contexts.

6. Conclusion

This paper discusses the extension of the categories of measurement and predicate in adjectives and phrases, analyzes the similarity between the Chinese trace adverb "you dian" and the English a bit, and points out that "you dian" is composed of the "(a) dian" in the measurement category and the "you" in the predicate category. Emphasize that 'a bit' is not a single vocabulary, and avoid mistaking it for an adverb in teaching. Explored the possibility of co-occurrence of functional categories and their matching with lexical category features.
