Chapter 1 Introduction
1.1 Background of the Study
词块的话题越来越多的精矿过去30年。贝克尔在1975年提出的概念大块，英语论文，后来许多学者开始探讨更加深入和系统，但不同的学者有不同的定义，命名它。有违宇宙观提出，人类的语言是类似的其他活动，其中大部分是依赖于反复记忆和使用，但不是靠盲目经验性创意，既不的语法规则可以结合一起暂时单个词。 （有违宇宙观，1975）。20世纪80年代以来，随着计算机语料库巨额的快速发展，语料库语言学开始从一个新的角度去探究的精髓语言生活。他们发现了存在大量的人类语言中的固定和半固定短语，它们可以被存储在内存中，可以容易且自动检索作为一个整体预制。更重要的是，刘易斯（1993年）出版的词汇的措施带来了新的观点SLA。 Heclaimed，语言是一个组合词块不是单个的词。所以，在语文教学中的教师开始诉诸周期的观察，假设，实验以外，利用演示生产实践的教学风格。Lexical chunks have been the topic of growing concentrate over the past thirtyyears. The notion of chunks was put by Becker in 1975, later many scholars began tostudy it more deeply and systematically, but different scholars had different definitionto name it. Bolinger puts forward that human language is similar to other activities,most of which are depend on the repeated memorize and use, but not depend on theproduction of creativity, neither the grammar rules can combine the single wordstogether temporary. (Bolinger, 1975). Since1980s, with the rapid development of hugeamount of computer corpus, the corpus linguistics began to explore the essence oflanguage from a new view. They had worked out that there exist a large number offixed and semi-fixed phrases in human language, they can be stored and prefabricatedin memory, which can be retrieved as a whole easily and automatically. What’s more,Lewis (1993) published The Lexical Approach brought a new view into SLA. Heclaimed that language was a combination of lexical chunks not single words. So inlanguage teaching teachers started to resort to the cycle of Observe- Hypothesize-Experiment other than utilizing the Presentation- Practice- Production teaching style.
Lexical chunks not only have got pragmatic functions, but also used to organize,construct and signal the discourse. So scholar had suspected the grammar-lexisdichotomy by the 1990s. Nattinger and DeCarrico(1992) declared that the short phrase is more sensible than the single word in the aspect of meaning.The significant role of lexical chunks in SLA has been focused by many scholars(e.g. Yorio,1980; Schmidt, 1983; Chambers, 1998; Wray, 2017; Wood, 2017). Also,Lexical chunks have aroused the interest of domestic researchers. They exploredlexical chunks from different perspectives. Till now, many domestic scholars hadalready testified through experiment that chunks competence has positive effect on thelanguage ability. Recently, there had a lot of studies of lexical chunks in appliedlanguage field, but most of them were focused on the speaking, writing and reading.The study of the positive effect lexical approach plays in enhancing the level ofcollege students’ EFL news listening is relatively few. So the thesis aims to start astudy on news listening.English listening comprehension is an important ability which L2 learners mustacquire.
1.2 Purpose of the study
Based on the past studies on the relationship between lexical chunks and Englishinput/output, the significance for my subject selection is to help the students to helpthe improving the English listening proficiency of English learners. And the listeningteaching based on lexical chunks may facilitate the learners acquire more lexicalchunks to their own linguistic repertoire, which can enhance the ability of listeningdiscourse comprehension.Thus, it’s important to raise learners’ awareness of lexical chunks and study how teachers help English learners to use lexical chunks in almost the sa，英语论文范文
