Semantic field theory is an important theory in semantics。 It can provide important theoretical foundation for English vocabulary learning。 From the perspective of semantic field theory, it is not enough to explain the meaning of the English vocabulary or require students to remember words in English books。 In theory, collecting English vocabulary into the suitable semantic field can guide students to understand vocabulary autonomously and remember meaningfully。 Moreover, the theory can improve the efficiency of teaching and the ability of using words。 In this study, the semantic field theory is the theoretical framework and can help us set up a new teaching model。

2。 Literature Review

2。1 Vocabulary

What is vocabulary? Nobody can give us a fixed answer in linguistic。 In the 19th century ,western linguists put forward a very famous definition:words are a kind of free organization form 。In this form, there is no less than its own freedom organization form。In short,the word is the smallest free form。 Vocabulary is significant in the language learning。 Lewis thinks that a foreign language learners' foreign language level directly affected by the level of vocabulary learning。 Based on the theory of philosophy, cognitive linguistics put forward the meaning of the words is closely related to people’s cognitive experience。 Therefore, both in the English vocabulary teaching and learning English vocabulary, teachers must pay more attention to comply with the laws of vocabulary itself exists and on this basis to choose a simple and high efficiency in English vocabulary teaching mode。文献综述

The key of English vocabulary learning is memorization。 About English vocabulary memory, domestic and foreign scholars have done a lot of researches。 Liu Qihui points out that the learners of English have some problems in vocabulary memory: English learners tend to focus on the meaning of vocabulary。The memory of words is non-single cognitive activity, but the overall learning process with the participation of a variety of cognitive activities。 In addition, the vocabulary memory activities are usually in the “psychological space’’ and “physical space’’。 From the point of contact and development to explore the whole memory activities, people are likely to show the nature of human memory activities and complex process。 Thus people can invent the scientific and effective vocabulary mnemonic system which promotes the development of English or other language teaching research。 Only the learners use a variety of methods such as the image, or the association into the vocabulary to analysis and thus they are easy to remember English vocabulary。 In other words, it is easy to remember vocabulary through meaning。 Therefore, this study will integrate a variety of factors from multiple angles and explore the junior middle school English vocabulary teaching mode under the guidance of the semantic field theory。 

2。2 Foreign Vocabulary Teaching Overview

The teaching method of foreign language that appeared at first in the west is the grammar translation method and this method also dominated for a long time。 In vocabulary teaching, the teachers often read the words firstly and then translate it into the native language, and then make a sentence with the word or do translation exercises to encourage learners in the learning process。 The grammar translation method lays particular stress on reading and writing, so it is not high efficient to improve learners’ oral communication ability。 To the end of 19th century, “direct method’’ was born。 In the direct method of vocabulary teaching, material object, pictures, models and presentations are introduced into the specific vocabulary。 The teachers usually teach abstract words through association of meaning。 “Direct method’’  is helpful to enhance the language sense, to improve language practice ability, especially listening and speaking ability。 Direct method has its own shortcomings, however, especially in the area of English vocabulary teaching, it is difficult to teach complex and abstract concepts。 So the teaching contents are limited to daily vocabulary and it is not conducive to the improvement of learners’ vocabulary。来,自,优.尔:论;文*网www.youerw.com +QQ752018766-
