An Experimentalanalysis On The Acquisition Of Chinese“Bei(被)” Sentence Intonation By Laos Students

Based on the broad idea of "Intonation pattern" and "Prosodic pattern" proposed by Professor Shi Feng and his researching team from Nankai University,this dissertation adopts the theory and method of experimental phonetics to do basic research from three aspects of "Intonation Pattern" : pitch range,lengthening rate and energy ration,and then analyzes from the perspective of focus by combining the theory and method of "Prosodic Pattern".This dissertation compares the intonation characteristics of "bei" sentences of Laotian Chinese learners with native Chinese speakers,finds out the similarities and differences between them,then explains the source,extends the "point" of "bei" sentence intonation to the "area" of the whole Chinese intonation acquisition,and finally puts forward the teaching suggestions.First of all,through the analysis of the intonation of the "bei" sentence of the Chinese native speakers,it is found that the speakers emphasize the patient subject and the verb structure.The patient subject and verb structure form two complementary focus respectively,and two complementary focus form a joint focus.Secondly,by studying the intonation pattern of the three groups of learners and combining the prosody matching results,the dissertation summarizes the dynamic change process of the acquisition of "bei" sentence intonation by Laotian Chinese learners.First,on the whole,there are "two changed,two unchanged".Changed 1:The change of the agentive object and the patient subject;Changed 2: The pitch range’s differentiation of verb and complement in the verb-complement structure;Unchanged 1: The prominence of the agentive object.Unchanged 2: The prominence of the preposition "bei".Second,from the perspective of prosodic matching paradigm,duration and volume are consistent,and There is a great difference between primary group and middle & advanced group,showing a watershed situation.Finally,the primary group,the intermediate group,the advanced group and the native group are connected,and the four groups of data form a continuum.This dissertation summarizes the errors,explains the source and puts forward countermeasures.Learners’ errors mainly lie in: 1.Dislocation of focus.Too much attention is paid to the agentive object,but the importance of patient subject and verb structure is ignored.2.Emphasize the grammatical structure.Too much emphasis on the preposition "bei".The reasons for the formation of errors lie in the neglect of teaching,the influence of mother tongue and cultural facts,the negative transfer of target language,the influence of learning strategies and communicative strategies.This dissertation puts forward some universal measures,such as enhance intonation awareness,emphasis on "visualization" intonation teaching,highlight the function of speech flow and targeted teaching in different stages and countries.
