Chapter 1 Introduction

1.1 Background of the Study
It is well known that any language learning is inseparable from the vocabulary;vocabulary plays a very important role in language learning. Vocabulary sustains thepronunciation and grammar. It is the basic unit of language and the cornerstone of improvinglearners’ language proficiency level. As Zimmerman says “Vocabulary is central to languageand of critical importance to the typical language learner”. (1997:134)Wilkins points out: “Without grammar very little can be conveyed; without vocabularynothing can be conveyed.” (1972:111). Thus it can be seen that the importance of vocabularyin the process of English learning. Any language skills are unable to neglect vocabularyelements and exist independently. Proper use of words is the key to producing language andconveying meaning expression and transmission of meaning.Bollinger (1970) states that “the quantity of information in the lexicon far outweighs thatin any other part of the language, and if there is anything to the notion of redundancy it shouldbe easier to reconstruct a message containing just words than one containing just the syntacticrelations. The significant fact is the subordinate role of grammar. The most important thing isto get the words in”. Based on Bollinger, the most important factor that affects understandingand application is the vocabulary. Vocabulary is the smallest meaningful unit of language.Human thinking activities and the exchange of ideas firstly depends on vocabulary. Withoutmastering proficiently vocabulary, it is impossible to master a language well. A learner’svocabulary size directly influences his ability of language expression, and then affects hisabundance and accuracy degree of thoughts expressing. In this sense, a mastery of vocabularyis the basis of cultivating the students’ ability of comprehensive use of language andrepresents the learners’ level of foreign language.
