| Minority-Han interlanguage is an approximative language system         that minority nationalities form and use in the process of contacting         with Han language (including second language learning).lt is a         dynamic linguistic system developing toward the approxy of target         language with its own features of linguistic structures and         pragmatic s . The study of Minority-Han interlanguage develops from         the æƒnterlanguage theory?and become an integrate part of it. Being         a universal linguistic fact in the areas of minority nationalities, it         has double value in theory and practice to be explored         systematically.            As Minority-Han interlanguage exists commonly in daily oral         communication ,this paper focuses on the phonetics of Minority-Han         interlanguage; explores the phonetic features of Minority-Han         interlanguage in the districts of minority nationalities in Yunnan         province; compares Minority-Han interlanguage with interlanguage         in foreign language teaching and learning; depicts mainly the         phonetic system of Yi-Han interlanguage , Bai-Han interlanguage         and Zhuang-Han interlanguage, combining investigating materials         and the complicated situation of language used in Yunnan         province ,and predicts the developing tendency of interlanguage         phonetics. The paper asserts that the phonetic system of         Minority-Han interlanguage, is formed by the influence of native         language background as well as the target language .It is a dynamic         process approaching the approxy of target language, which is         initially influenced by native language and retain major phonetic         elements of minority languages, but as it develops, the elements of         native language reduces while the phonetic elements of Han         language and approximative Han language increase.            The paper also emphasizes that the study of the phonetics of         Minority-Han interlanguage is of significance to the bilingual         education, Putonghua teaching in the areas of minority nationalities         and in the field of teaching Chinese to foreign students, as well. |
