Experimental Study On Lengthening Ratio Of Chinese Focus Sentences By Thailand Middle School Students

This paper collected 15 Thai students focus words pronunciation material,stoneblade intonation pattern in time to stop delay rate as the foundation,through the experiment,the method of using Praat speech experiment software,about 15 Thai students(primary,intermediate and advanced Chinese level students each 5)say mandarin Chinese emphasize the focus words is analyzed.With the natural focus sentence as the basic sentence,the first sentence,the middle sentence,the end sentence and the verb-object focus sentence as the change sentence pattern,the internal focus sentence is contrastively analyzed by the prosodic hierarchy contrast method.At the same time,this paper makes a comparative analysis on the length ratio of sentence patterns corresponding to Putonghua in order to summarize the characteristics of Thai middle school students’ Chinese emphasis on focus sentences.On this basis,this paper analyzes the causes of errors such as negative transfer of mother tongue,and puts forward some teaching suggestions,such as strengthening the sensitivity to focus.It is hoped that it can provide help to the Chinese teachers and teacher volunteers who will go to Thailand in the future,and promote the development of Chinese in Thailand.This paper is divided into six parts.The first chapter is the introduction,which discusses the concepts of stop-delay rate and length ratio,introduces and analyzes the previous research on stop-delay rate,and elaborates the specific methods and processes of this speech experiment.The second chapter is the experimental analysis of word length ratio.From the perspective of three different levels of Chinese in junior high school and senior high school,this paper analyzes the performance of the length ratio of each word in the focus sentence of Thai middle school students.No matter what the focus sentence,Thai middle school students consistently extended the first word and the last word of the sentence and the one-word verb.The third chapter is the experimental analysis of the length ratio of prosodic words.According to the classification of four tones in Yin and Yang,the ratio of word length to length in various focus sentences was analyzed.It is concluded that the corresponding focus words are lengthened at the beginning of a sentence and the verb-object focus,but not at the middle and end of a sentence when the focus is emphasized.The fourth chapter compares and analyzes the experimental data of Chinese native speakers and Thai middle school students,and finds that the distribution pattern of the length ratio of Thai middle school students is similar to that of Chinese native speakers,but there are some differences.Especially for prosodic words at the end of sentences,Chinese native speakers showed an upward trend,while Thai middle school students showed a downward trend.With the continuous improvement of their Chinese proficiency,Thai middle school students are getting better at emphasizing the focus,and their pronunciation is getting closer to that of Chinese native speakers.The fifth chapter summarizes the characteristics of acquisition and the causes of errors,and gives teaching suggestions.The main reasons for the errors are the negative transfer of Thai language and the students’ wrong understanding of the focus.In view of these reasons,this paper puts forward some suggestions on the teaching of declarative sentences with emphasis on the focus,such as strengthening the students’ sensitivity to the focus,arranging the teaching sequence reasonably,making full use of the positive transfer of mother tongue,etc.,in the hope of helping future Chinese teacher volunteers better conduct Chinese teaching.The sixth part is the summary,which is the summary of the experiment that emphasizes the focus of the statement sentence and the reflection of the experimental research.At the same time,it also gives a detailed explanation of the innovation and deficiency of this paper.
