Collected about 1,750 minutes of conversation content in 35 episodes of "Informal Talks VI",transcribed the speeches of foreign guests in the program into text through i FLYTEK software and manual proofreading,and established a corpus of about 500,000 words.A corpus analysis and a comparative analysis were used to examine the use of the preposition "Zai" by the 11 resident foreign guests in the program.The first part: To collect the use of the preposition "Zai" by the 11 foreign guests in Informal Talks Ⅵ and count the correct and incorrect rates.The second part: Through the analysis of the use of the preposition "Zai" by foreign guests reveals that there are errors in the acquisition of the preposition "Zai" in three aspects: preposition misorder,omission of prepositions and placers,and misuse of prepositions and place-to-place words.The third part: the causes of the errors were analyzed,and the objective influences were negative native language transfer,generalization of the target language rules.Among them,the negative migration of the native language of each country is specifically analyzed from the perspective of different native languages of the guests of each country,such as the influence of English subordinate clauses,the different order of Thai gerunds from Chinese,and the fact that Russian prepositions do not need to add azimuths.The effects of subjective causes are mainly the use of communicative strategies and indiⅥdual learners’ differences.The forth part : Some suggestions are pro Ⅵ ded for teaching Chinese as a foreign language with the preposition "Zai".Suggestions for teachers include teaching in stages and arranging teaching sessions rationally;focusing on the comparative analysis teaching method;and emphasizing the teaching of common collocations of prepositions.Suggestions for learners include rational understanding of errors and efforts to avoid them;finding appropriate learning methods and communicative strategies;listening carefully in class and strengthening practice in class.At the same time,we propose to use the anchor teaching method to introduce Informal Talks into the classroom for speaking Chinese as a foreign language,so as to proⅥde a realistic context for teaching and practice. |
