Words with grammatical functions of two or more classes of words and closely related meanings are called concurrent words.The premise of the existence of the same class is that two or more parts of speech of the same word are separated in the syntactic function and meaning expression of the existence of a small overlap,learner learning process often has difficult to remember,distinguish and to use,naturally become a difficult point in the process of second language teaching."Gei" is a Grade A vocabulary in the "Chinese Level Vocabulary and Chinese Character Grade Outline",which has three parts of speech: verb,preposition and auxiliary,and words of different parts of speech have different syntactic distribution positions,and naturally have different semantic and pragmatic expression functions.The verb "Gei" is a typical handover verb,which can carry double objects,and in the process of verbal communication,only the indirect object of the person can also appear only the direct object of the object;the double object phrase is used as a predicate or the central language of the predicate,which constitutes a double object sentence,and can also appear in the definite and subject object positions.The preposition "Gei" is made up of the verb "Gei",and the introductory object constitutes a prepositional phrase,usually appearing in the position of the adjective,complement or definite,the syntactic distribution position is slightly intersected,and semantically can introduce a variety of semantic components such as the act of doing,the recipient,the beneficiary or the injured,the servicer and so on.The semantic function of the preposition "Gei" to introduce the administration and the passive mark of the auxiliary word "Gei" are also related in the sense,and the auxiliary word "Gei" only appears in the predicate central verb table passive,which has the effect of emphasizing the mark.We selected the "Gei" of the concurrent words as the research object,took the specific bias corpus in the HSK dynamic composition corpus of Beijing Language and Culture University as the research scope for classification investigation,combined with the syntactic semantic semantics of different word classes to define the situation of different types of bias,analyzed the mechanism and cause of the existence of different types of bias,proposed corresponding corrective measures,and then proposed targeted teaching strategies and learning strategies,providing a case reference for the study of the bias phenomenon of concurrent words.In the corpus,we found 273 misuse bias corpora of "Gei",82 redundant bias corpora,and78 missing biases,and this article focuses on typical misuse bias.First of all,the syntax,semantics,and pragmatic use rules of "giving" different word classes are described as criteria for defining different categories of bias and the basis for error analysis;secondly,the semantic bias categories of different parts of speech of "Gei" are sorted out from a specific corpus range,of which the number of corpuses of verb bias is small,and the verb "Gei" In addition to the expression bias of the handover meaning,there is also a small amount of misuse with the present meaning,directional meaning,and judgmental verb;the misuse of the preposition "Gei" is more complicated.There are not only misuse biases in part-of-speech,but also different degrees of misuse of prepositions similar to semantics in the expression of transmission meaning,directional meaning,beneficiary,and passive meaning;the bias situation of the auxiliary word "Gei" is relatively single,and there is only a difference in usage with the preposition that introduces the application component;Then,the reasons for the formation of different categories of bias are summarized into four items: semantic correlation of word classes,similar functions of synonyms,same syntactic distribution positions,and inconsistent semantic expression choices and pragmatic expressions,and on this basis,corresponding teaching and learning suggestions are proposed. |
