Research Of Lao's Conjunctions Acquisition Under Perspective Of Dynamic System Theory

As one of the function words,conjunctions have many grammatical functions and changeable semantic relations,which play an important role in the expression of people's words.But conjunctions are not easy to learn.Conjunctions are complex in syntactic,semantic and pragmatic functions.There are concurrently phenomena with adverbs and prepositions.On the other hand,the number of words is large and the frequency gap is large.The phenomenon of overgeneralization is often seen in the output of foreign students.We have found that conjunctions are the main difficulty for Laos students in Laos students' corpus statistics and practical teaching.The study of the acquisition of conjunctions will help the Laos students to learn Chinese better,and help the teachers to improve the teaching order through the order of conjunctions acquisition,to better arrange the teaching plan and to make the teaching more targeted.This paper finds that Laos will be influenced by the mother tongue when learning conjunctions.This influence mainly occurs in the semantics of conjunctions,location,collocation,pragmatics,punctuation and so on.It is reflected in the use of conjunctions in Laos students,except for conjunctions,the semantic and location are the first acquisition;the collocation often refers to the mother tongue,and the mother tongue has some collocations,such as "although...However,Lao students usually do not omit or mix up mistakes,but if there is no matching in their mother tongue,such as " because...Therefore,students will rarely use such a collocation;pragmatics often use the conjunctions "single use","single use" is the full stage of the situation,in almost all the corpus with sufficient data conjunctions,thus resulting in the "formal association" such phenomenon;punctuation error is also the error of the whole stage of the error.In addition,the tendency of chemical fossilization is mainly embodied in the absence of a sentence between clauses and clauses,especially in the beginning of the conjunctions.On the basis of error analysis,we analyze the order of acquisition of conjunctions in Laos,which are: He> Zhiyao> Gen> Wulun> Suiran> Ke> Bingqie> Bing> Danshi> Bujin> Yu> Huozhe> Dan> Haishi> Suoyi> Yinwei> Erqie> Ranhou> Buguan> Yaoshi> Ruguo> Budan> Jiran> Jishi > Er> Huo> Youyu> Napa/ Suishuo/ Hekuang/ Shenzhi/ Fouze/ Ruo/ Sui/ Raner/ Ji> Bulun/ Kuangqie/ Jiaru/ Wanyi/ Zhiyou/ Yi/ Yimian> Buguo/ Buran/ Yuqi/ Zongzhi/ Yinci/ Qie> Ru> Jiusuan/ Buguang> Xiangfan/ Keshi/ Jinguan> Chufei/Yaobushi/Zhishi>Ciwai/Conger/Gu/Yiji/Yin/Yushi/Zaishuo.At the end of the study,we give corresponding teaching suggestions for each semantic conjunction.
