1.1 Research Background
从2O世纪后期，语言学家已经开始认识到词汇的重要性，在语言学。正如许多学者在国内外指出，词汇教学研究，第二语言习得和外语教学领域中扮演一个非常重要的组成部分。语言学家威尔金斯（1972年：111）说，“没有语法，很少可以传达，没有词汇，没有什么可以传达”。麦卡锡Lexicologist（1990：23）也强调在语言词汇的重要性：“不管你有多好学生学语法，不管如何成功他掌握第二语言的声音，没有的话表达了广泛的含义，沟通，语言不能发生任何有意义的方式“，但语言词汇的研究是仍然相对每种不超过语言学等方面，就像杜宾提到，”现代语言学理论放在很少强调对词汇，重点更多在结构，功能，观念，交际策略“（杜宾等，2002：112）。在同样的时间，到第二语言（L2）的学习者面临的最大问题之一是如何提高词汇很长一段时间有效。From the late 20thcentury, linguists have started to recognize the importance ofvocabulary in linguistics. As many scholars at home and abroad pointing out, thevocabulary teaching study is playing a very important part in the field of secondlanguage acquisition and foreign language teaching. Linguist Wilkins (1972: 111) said,“Without grammar, very little can be conveyed, without vocabulary, nothing can beconveyed”. Lexicologist McCarthy (1990: 23) also emphasized the importance ofvocabulary in a language: “No matter how well the student learns grammar, no matterhow successfully he masters the sounds of a second language, without words toexpress a wide range of meanings, communication in that language cannot happen inany meaningful way.” But the linguistic studies on vocabulary are still relatively lessthan other aspects of linguistics, just like Dubin mentioned that “Modern linguistictheories have placed little emphasis on vocabulary, focusing more on structures,functions, notions, and communicative strategies” (Dubin et al, 2002: 112). At thesame time, one of the biggest problems facing to the second language (L2) learnershas been how to enhance vocabulary efficiently for a long time.
正如我们所知道的，“构词或构词的词汇扩大的一个重要手段”（林承璋，刘世平，2005:211）。构词“，在其狭义是指词的变化过程中的信号词法关系”（胡壮麟，2001：88）。一般来说，构词指构词的过程。和推导是在英语中的构词的主要过程之一。作为一个字形成的主要过程，“推导可以定义为在一个过程中形成新的字一个字元素添加前缀，后缀或组合的形式，例如，一个已经存在的字。”（SBONE1980），它是也称为加盖，因为，由，添加词缀各种基础，可以形成许多新词。通常被定义为一个字的形成过程，其中创建的新词添加前缀或后缀，或两者的基础“（张韵斐，2004:42），”推导或加盖。总之，衍生或加盖形成新词是一个非常重要的途径。人们普遍认为，词缀构词的重要组成部分，和推导是英语学习者的有效方法，以提高他们的词汇量。这就是为什么很多英语老师到教室介绍贴上知识。As we know, “word formation or word building is an important means ofvocabulary enlargement” (林承璋，刘世平，2005：211). Word formation, “in itsrestricted sense, refers to the process of word variations signaling lexicalrelationships” (胡壮麟, 2001: 88). Generally speaking, word formation refers to theprocesses of constructing words. And derivation is one of the major processes of wordformation in English. As one of major process of word formation, “derivation may bedefined as a process of forming new words by the adding of a word element, such asprefix, suffix or combining form, to an already existing word.” (SBONE1980) It isalso called affixation, because by adding with all kinds of affixes to a base, many newwords can be formed. “Derivation or affixation is generally defined as a wordformation process by which new words are created by adding a prefix, or suffix, orboth, to the base” (张韵斐，2004：42). In a word, derivation or affixation is a veryimportant way in forming new words.It is generally agreed that affixes are the essential components for wordformation, and derivation is an effective technique for English learners to enhancetheir vocabulary. That is why many English teachers introduce affix knowledge to theclassroom. “The productivity of word formation has, over the centuries, been a majorfactor in providing the huge vocabulary of English, and the fact that the process ofcreating new lexemes with new forms has not faded out can be seen by consulting 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。
