Vocabulary is the driving force of bet365 Play online games production and the key to speech understanding。In Second bet365 Play online games Teaching，Vocabulary teaching is the basis of second bet365 Play online games teaching。Develop second bet365 Play online games skills，We often start with the simplest vocabulary learning，Building a “mental dictionary” of a second bet365 Play online games。“Mental dictionary” refers to people’s mental storage of words, their meanings and related knowledge。Not only the words themselves are stored in the "mental dictionary"，Also stores the voices related to it、Semantics、Syntax、Pragmatic and other information。Foreign learners in the process of learning Chinese，Will gradually build a Chinese “mental dictionary”。

　　Brief analysis of relevant theoretical models

As early as the 1950s and 1960s，Western academic circles have begun to pay attention to the development of second bet365 Play online games learners’ mental dictionary representation，And proposed a series of theoretical models。In the Western second bet365 Play online games teaching research community，One of the most widely influential psychological dictionary theories，It’s J. F. Kroll and E. Revised Hierarchical Model proposed by Steward。The model thinks，The native vocabulary and second bet365 Play online games vocabulary of second bet365 Play online games learners are represented and stored separately。Concepts are directly linked to native vocabulary，For second bet365 Play online games beginners，L2 vocabulary is linked to concepts through the mother tongue。The strength of the connection between L2 and L1 lexical representations is stronger than in the opposite direction，The connection strength between the first bet365 Play online games and the concept is stronger than that between the second bet365 Play online games and the concept。As learners’ second bet365 Play online games fluency improves，Second bet365 Play online games vocabulary gradually breaks away from the mother tongue，Start making direct connections to concepts，The strength of the connection also gradually increases with the improvement of second bet365 Play online games learners。2000，Jiang Nan studied the development stages of the mental dictionary from the perspective of second bet365 Play online games learning，Propose a representation model of second bet365 Play online games vocabulary development in classroom teaching environment。According to this model，Learners’ vocabulary development goes through three stages。The first stage is the formal stage。At this stage，Learners should remember the pronunciation of second bet365 Play online games vocabulary、Form information such as spelling，And establish a connection with the corresponding vocabulary of the first bet365 Play online games。The second stage is the L1 lemma mediation stage。The first bet365 Play online games entry information is copied or appended to the second bet365 Play online games vocabulary information，Form a special second bet365 Play online games adjustment vocabulary，Its form is L2，But both semantic and syntactic information are the same。The third stage is the second bet365 Play online games integration stage (L2 integration stage)。The learner extracted the semantic meaning of the second bet365 Play online games vocabulary、Syntax、morphological characteristics，Integrate into the entry，The representation and processing of vocabulary in the second bet365 Play online games are basically the same as those in the first bet365 Play online games。

The above theoretical model answers questions about the development patterns of lexical and conceptual representations in second bet365 Play online games learners’ mental lexicon，Played an important role in the field of psychological dictionary research。

　　Multiple factors influence the construction of second bet365 Play online games mental dictionary

Domestic research on the mental lexicon of Chinese second bet365 Play online games learners started at the end of the 20th century，Early research content mostly examined learners’ vocabulary acquisition。After entering the 21st century，Discussions on this issue are gradually increasing，In-depth development of both themes and methods。Research findings，Unique forms in Chinese、sound、righteous relationship，Making the construction of Chinese second bet365 Play online games mental dictionary unique，Affected by many factors，Mainly include the following aspects。

First，Learner’s native bet365 Play online games background。The native mental dictionary plays a bridge role in the construction process of the second bet365 Play online games mental dictionary。The relationship between second bet365 Play online games vocabulary and mother tongue vocabulary is always changing。Learners with different levels of Chinese have different depths of understanding of words，The structures of mental dictionaries are also different。If beginner Korean Chinese learners rely on the speech channel，Make it easier to establish connections between words with similar pronunciations in Chinese and native bet365 Play online games；Learners who have a certain foundation in Chinese characters choose the word form channel and the whole word channel。In semantics，Learners master the common meanings in their mother tongue and Chinese earlier，bet365 Play online games-specific meanings begin to interfere with the development of the second bet365 Play online games mental dictionary at the intermediate stage，Learners cannot establish a relatively complete second bet365 Play online games mental dictionary until the advanced stage，Get rid of the interference of mother tongue。

Second，Learner’s bet365 Play online games level。Whether it is a modified hierarchical model，Still develop representation model，It is believed that the representation of second bet365 Play online games learners’ mental lexicon is constantly changing with the development of bet365 Play online games proficiency，In the research literature on Chinese second bet365 Play online games psychological lexicon，Many studies have used bet365 Play online games level as an important variable。Learners with different levels of Chinese have different mental dictionary structures，This is caused by learners’ different depth of understanding of words。Elementary level learners rely on the phonological channel between mental dictionaries to process vocabulary，The organization method of synonyms mostly uses entries as the basic organizational unit，Adopt lexical connection model for processing homographs，Adopt multi-pathway model for processing heteromorphic words；Advanced level learners have multiple choice of word form channel and whole word channel to process vocabulary，Using meaning as the basic unit to organize and process synonyms，Word processing completely adopts multi-pathway model。

　Third，Learners’ vocabulary collocation knowledge。Xing Hongbing thinks，Word collocation knowledge is syntactic information、Semantic relationship、Reflection of usage frequency information in the psychological dictionary。Second bet365 Play online games vocabulary learning is a process in which second bet365 Play online games learners gradually enrich their Chinese vocabulary collocation knowledge，This process involves increasing the number of collocated words、Rich combination types、Distinguish the collocation range of similar words，And form a Chinese vocabulary knowledge system on this basis。

　Fourth，bet365 Play online games input method。For most beginner Chinese learners，The first way to input words is input in classroom situations，The second is input in natural scenarios。Teaching input is the main means to help students collect words，Communicative input is an auxiliary means，The combination of the two can effectively help learners consolidate and expand their mental lexicon。

　　Chinese second bet365 Play online games vocabulary teaching benefits from this

Although the research on Chinese second bet365 Play online games psychological lexicon started late，But rich in content，Diverse methods，Existing macro research，There are also microscopic studies；Research on acquisition of existing learners，There is also research on teacher teaching；Description of existing phenomena，There are also reasons and theoretical explanations。These research results have solved many problems in vocabulary teaching and learning，Irreplaceable theoretical significance and teaching value。It is manifested in the following points。

First，Tracking the development process of Chinese second bet365 Play online games vocabulary。Including different native languages、The basic unit of the mental dictionary of Chinese second bet365 Play online games learners at different levels at different stages，Changes in the way of contacting native vocabulary、Changes in the depth of vocabulary processing。How Chinese learners learn vocabulary，Is the acquisition process the same as that of native Chinese speakers。Solutions to these problems，Provides theoretical basis and method guidance for graded teaching of Chinese vocabulary。

Second，Clear the characteristics of Chinese second bet365 Play online games vocabulary。Including the representation characteristics of the mental dictionary in the learner’s brain，Single word form、sound、The connection model of the three systems，How different words form lexical networks，How connection strength changes，The representation specificity of the mental lexicon of learners from overseas Chinese and East Asian cultural circles, etc.。The solutions to these problems provide theoretical basis and method guidance for the national (bet365 Play online games) teaching of Chinese vocabulary。

　Third，Improving the efficiency of Chinese second bet365 Play online games vocabulary teaching。According to the characteristics and development rules of Chinese second bet365 Play online games psychological lexicon，Teachers can adopt more targeted teaching methods，To improve teaching efficiency。The construction of mental dictionary is the formation process of a complete lexical proposition network，According to this characteristic，Teacher when teaching new words，You can use related vocabulary you have learned as the origin，Activation diffusion through the connection between form, sound and meaning，Reorganized vocabulary network，Develop students’ word association ability，Improve the clarity between the representations of each unit and its related connections in students’ Chinese mental lexicon。

In summary，The current research on Chinese L2 mental lexicon focuses on the characteristics of mental lexicon、Preliminary exploration of development and other issues，And compare different native languages、Differences in mental dictionary construction among learners at different levels。In research methods，Influenced by the West，Extensive use of empirical research methods and corpus methods，Using quantitative research methods for data analysis。Also，Since the study of psychological lexicon is also a concern of cognitive psychology，Some scholars have introduced psychological research methods into the study of Chinese second bet365 Play online games vocabulary acquisition，such as starting paradigm、stroop paradigm, etc.，These have greatly enriched the methods of Chinese psychological dictionary research。But，There are still a lot of issues to be studied。For example，Chinese vocabulary has its own characteristics，Quantifier、How to establish a mental dictionary of unique words such as dynamic particles，Need to explore further。Zaru，Existing research subjects have focused on native English speakers and Japanese、Native Chinese speakers。With the implementation of the “One Belt, One Road” initiative，Southeast Asia、The number of Chinese bet365 Play online games learners in Central Asian countries is gradually increasing，Research on nationalized psychological dictionaries for native speakers of these minority languages ​​still needs to be strengthened。

In the process of international promotion of Chinese bet365 Play online games，Vocabulary teaching as an important part of bet365 Play online games learning，The importance cannot be underestimated。Research on the mental dictionary of Chinese second bet365 Play online games learners，Can better reveal the characteristics and rules of vocabulary acquisition，Help improve existing teaching methods，Improve teaching efficiency。In the long run，It helps to improve the implementation efficiency of the Chinese international promotion strategy，Should continue to pay attention。
