Current researches show little attention to this structure and thus this paper is devoted to an overall understanding of this structure. The content of this thesis focuses on the following three aspects:First, when restricting the potential semantic range of noun phrases with its own proposition, the modifying clauses in English and Chinese share the same semantic features. That is to say, the modified noun phrase and the predicate of the clause depend on each other for existence. This semantic restrictiveness is obligatory for the clause and the noun phrase it modifies in both languages. Second, though sharing the same potential conceptual meaning, the combination of a clause and its modified noun phrase shows different syntactic position in surface structure as well as the inner structure of the clause. Based on a full description of syntactic characteristics of this kind of clause, the present thesis points out the differences and similarities existing in surface structure between English and Chinese. Finally, under the guidance of Chomskys Minimalist Program(1995), the thesis analyses the derivational processes of this structure in both languages.

现有的对比研究对于该结构的探讨，不论是在描述和解释上都是不完备的，为了深化这一句法结构的认识，本文从如下几个方面对英汉分句作定语修饰名词的现象进行了对比：首先，分句用自身的命题限制中心名词的语义范围时，在两种语言中具有相同的语义特征，即中心名词与分句内部的谓词之间存在依存关系，分句修饰名词必然受到语义的限制，是英汉两种语言必须共同遵守的准则；其次，英汉两种语言中表达相同概念意义的这一句法单位与其修饰的名词结合后，在表层结构中体现出不同的位置关系，且分句内部的句法结构也各有特点，本文在充分对其句法特征描述的基础上，指出二者在表层形式上的差异和共性；最后，尝试在乔姆斯基的最简方案(1995)框架内，演示英汉两种语言。

This paper analyzes, from voice, vocabulary, syntax and Context angles to analyze the causes of Ambiguity in English : English, homophone Words and speech courses. often lead to ambiguous; Ambiguity and the vocabulary is more than just words and often with difficulties arising; This paper also cited a focus on syntactic structure led to a number of interpretations, including regular structure, transitive verb with double-bin structure, vocabulary twists and turns, modified or modified sentence, phrase,sentence structure comparison, the Infinitive structure, Adverbial structure, and caused discrepancy conjunctions and other clauses; There Context discrepancy.

本文从语音、词汇、句法结构和语境等角度系统探讨了英语中歧义的起因：在英语中，同音异义词和连读常常导致语音歧义；而词汇歧义常常是由多义词和同形异义引起的；本文还重点列举了导致歧义的多个句法结构，其中包括有否定结构，及物动词加双宾结构，词汇曲折变化，修饰短语或修饰句，比较句结构，动词不定式结构，状语结构，连词 and 引起歧义和其它从句等；另外还有语境歧义。

In contemporary Chinese, the combination of Noun and Verb can constitute three different structures:"NV"nominal modifying structure,"NV"verbal modifying structure,"NV"subject-predicate structure. This structure is worthy of researching because the location of it's internal component's is dispute, that is to say, whether the headword of nounbial modifier structure is verb, and whether the headword of verbal modifying structure can be noun are disputable problems.

现代汉语中，名词和动词的组合可以构成三类结构：定中偏正结构、状中偏正结构、主谓结构，由于其内部成分的定位存在着值得争议的地方，即定中偏正结构的中心词是否为动词；状中偏正结构的修饰语能否为名词，且容易出现同形异构结构，所以这类结构值得研究。
