| Language is the most important communication tool in human society,and the ultimate indicator of second language learning is whether learners can communicate language smoothly.In the real language environment,the oral bias of second language learners can lead to communication failure.The "Chinese Bridge" World Student Chinese Competition not only gives learners who love Chinese all over the world a chance to show and communicate,but also shows the current level of Chinese teaching worldwide.In the course of the competition,different levels of learners in different countries of oral output,there will be different types of oral bias,and written language bias is both the same,but also fundamental differences.In the course of the competition,the oral bias,is the player after the pre-match preparation,more reflect the player’s true language level,so choose the game appeared in the oral bias as a language material.The specific research in this paper is as follows:In the introduction part,introduce the research reasons and background,discuss in detail the "Chinese Bridge" world college students Chinese competition research status quo and oral bias research status quo,through the study of these existing results,found that in the analysis of bias,the micro-study has been relatively much,but the learner oral error macro-study is not enough.The follow-up research is mainly carried out by bias analysis,statistical analysis and comparative analysis.The second part is the key part of the thesis.First of all,it introduces the general situation of the "Chinese Bridge" competition,and focuses on the general situation of the "Chinese Bridge" world college students’ Chinese competition,as well as the competition system of the "theme speech" link.Second,collect all the real materials from the "Chinese Bridge" World University Students’ Chinese Competition keynote speech and question-and-answer section for the three years 2 016,2 017,and 2019,and organize the resulting oral output bias into a small self-built corpus.Then,all spoken biased materials are filtered and classified,organized according to grammatical bias,vocabulary bias and discourse bias,respectively,to count the number and proportion of bias.According to the proportion,the grammatical bias is divided into five categories: misalignment,misalignment,omission,misalignment,misalignment of vocabulary into three categories: near-meaning error,word meaning repetition or inclusion,and mispronounced allegations,and the error of discourse is divided into three categories of misalignment,unclear meaning,logical confusion.The third part,combined with the learner’s oral bias example sentence,analyzes the causes of bias,including the negative migration of mother tongue,the generalization of the rules of destination language,the subjective reasons of learners and the characteristics of spoken language itself,the reason analysis will provide a basis for the subsequent suggestions to reduce oral bias.The fourth part,in view of the characteristics and reasons of the study of oral bias,from the teacher’s oral teaching,students’ oral practice,the preparation of oral teaching materials,Chinese oral competition four aspects of the proposal. |
