earer knows the referent[士HK]. Compared with ACP and FH. Semantic Wheel Model (which itself was d onBickerton. 1981) has been one of the most widely used models for classifying NPenvironments in English article acquisition studies and is used as well in this study. Unlikethe traditional research that paid attention only to the presence or absence of articles inobligatory context, Huebner" s analysis includes two important aspects: Firstly, the varioussemantic functions or types of NPs and the article(s) used with each semantic type: andsecondly, the relationship between the development of FSL learners* grasp of the articleand NP function. In this sense. Semantic Wheel Model is id to explain the accuratearticles use of Chinese college learners, and further analyze their non-target-like use ofarticles  a semantic perspective

　　1-2 Purpose and significance of the study研究意义和目的
　　In recent years, there are two salient problems in the article use. The first one is thatlearners omit article when they should use it; the second is that there are partitive mistakesof substituting definite article the for indefinite afnj and substituting a(n) for ihe. Somescholars believe that such behaviour of second language learners (SLL) is the resultproduced by syntax and semantic feature which have no access to Universal Grammar(UG). Others, however, argue that article use of L2 controlled by a principle is regular,which just embodies the accessibility of semantic feature in the UG. The causes of this aredisputable among researchers, which include Article Choice Parameter (ACP), FluctuationHypothesis (FH) and Semantic Wheel Model (SWM). The research is aimed to explore therelationship between the use of English articles and four semantic contexts (Type 1 [—SR,+HK]. Type 2 [+SR. +HK]. Type 3 [+SR. -HK]. Type 4 [-SR. -HK]) in order to explorehow different semantic contexts influence the article use, and to help learners improvetheir performance on the English article system.The significance of this study lies in a new experimental approach employed in theexperiment: Use E-prime software in fill-in-the-article task to test articles' accuracy rateand reaction time. This is different  previous research to investigate the accuracy rateof article use in the text. If the reaction time or processing time is shorter and accuracy rateof choosing articles is higher in certain semantic type, in this sense, it would provideevidence for the argument that it is easier to learn for L2 learners in this semantic type. Ifthe reaction time is longer and many errors are occurred, then it would be difficult For 12learners to learn in this semantic type. In addition, in the study, it may help to realize somepedagogical purposes and attempt to propose some pedagogical strategics which aresupposed to be feasible and practical in Chinese ting.

　　The thesis is made up of six parts. To be more specific, it reveals as follows:Chapter One presents the general introduction to the thesis, including researchbackground concerning three important theories in English article use and the purpose andsignificance of the study.Chapter Two covers the literature review of this research topic. First, it shows theclassification of noun phrase and definition of definiteness and specificity. Then itdiscusses three important theories concerning article use  a semantic perspective.Next, previous article research本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
