| Positive and negative interrogative sentences are special interrogative sentences in the Sino-Tibetan language family.Their sentence patterns are flexible and involve many Chinese grammar knowledge points.Different foreign students with different language backgrounds will inevitably produce various kinds of errors in the process of acquiring positive and negative questions.Therefore,the dissertation chooses the errors of the foreign students’ positive and negative interrogative sentences as the objects of study.Based on the theory of error analysis,the dissertation chooses the data of three aspects and explores the errors of foreign students’ positive and negative questions.The study of the acquisition of positive and negative questions can supplement the research of positive and negative questions in the second language acquisition,and it can also promote the acquisition of foreign students’ interrogative sentences.The paper summarizes the ontology research of positive and negative interrogative sentences and the study of second language acquisition.Finds that the ontological research of positive and negative interrogative sentences is relatively complete,but there are relatively few researches in second language acquisition,and the research is mostly focused on "V 不 V","A 不 A","N 不 N",and the other basic types of positive and negative forms of questioning,ignoring other syntactic elements in the positive and negative questions,resulting that source of errors and errors are the same.Therefore,the dissertation analyzes the errors of the positive and negative questions of foreign students in China according to sentence patterns,syntax elements and question focus.Firstly,the dissertation classifies the positive and negative question sentences into seven categories:"X不X","VO不VO","predicate-complement structure","preposition phrase+predicate component","verb-adverbial structure","是不是",“additional question”.Then,according to the questionnaire,it summarize the acquisition of positive and negative questions of foreign students in China.According to the analysis,foreign students have general knowledge of positive and negative questions,and it is easy to confuse positive and negative questions with other question sentences.The forms of positive and negative questions currently held by international students are mainly"是不是+predicate","AB不A"and"X不".Based on the above summary of the formal structure of positive and negative questions and the summary of the acquisition of positive and negative interrogative sentences of international students in China,the paper classifies the positive and negative interrogative errors into nine categories:the errors of"X不X",the errors of"VO不VO",the errors of"predicate-complement structure",the errors of"verb-adverbial structure",the errors of"是不是",incorrectly added"吗",the errors of auxiliary word"了",the errors of confusion of"不"and"没(有)",the errors of the generalization of"没(有)".The paper makes a detailed description and analysis of the errors,and finds that the reason why foreign students produce so many errors in the acquisition of positive and negative questions.Foreign students are unfamiliar with the definition of the positive and negative questions and the knowledge of the target language.The media language of teaching and the teaching materials also affect their learning.Then,based on the characteristics of foreign students’ acquisition of positive and negative questions and the experience of practice,it is suggested that teachers should define the positive and negative questions in teaching,strengthen the comparison between the different forms of positive and negative questions and related Chinese knowledge,and study and review the positive and negative questions in various ways. |
