| Verb-direction phrase "V+guolai" and "V+guoqu" is an extremely important content in the teaching of Chinese as a foreign language,the grammatical meaning of them are very rich. They have developed and evolved some extended meaning from the original directional meaning.Verb-direction phrase "V+guolai" and"V+guoqu" have drew many scholar’s attention,and the scholars also analyzed the two phrases from grammatical meaning,syntactic structure and many other aspects.Based on the predecessor’s research achievement, we conduct investigation and use them for reference,meanwhile,we take advantage of Chinese interlanguage corpus to inspect and analyze the verb-direction phrase""V+guolai" and "V+guoqu" from two aspects of semantic and syntax,we find the usage of semantic and syntax correctly are the highest.This suggests that foreign students have mastered the semantic and syntax of the two relatively well.Then we analyze the four types of errors:omission,addition,wrong alternation and disorder,it mainly includes omission and addition of verb and "guolai/guoqu",wrong alternation of "guolai" and"guoqu",as well as disorder between "V+guolai/guoqu" and object.The total error rate of "V+guolai" is higher than "V+guoqu",it related to usage rate and acquisition difficulty of the two.Then we analyze the causes of errors,including complexity of verb-direction phrase,negative transfer of native language and the target language knowledge,the influence of learning strategy and communication strategy.At the same time,the text makes use of junior and senior foreign student’s sentences to conduct the comparative research of "V+guolai" and "V+guoqu" of acquisition condition,it includes grammatical meaning and syntactic structure.At the primary stage ,for foreign students, the acquisition condition of original meaning of the two is better. At middle and advanced level, foreign students can use more extended meaning.But because the acquisition difficulty of "V+guoqu" is bigger than"V+guolai",foreign students still tend to use its original meaning at middle and advanced level.In terms of acquisition condition of syntactic structure,the usage rate of "V+guolai/guoqu" without object is the highest,hence.it is easy for foreign students to learn.Then we can conclude acquisition rules to guide foreign students to learn"V+guolai" and "V+guoqu" in a even better way. Final]y,I conclude some suggestions in textbooks and teaching for verb-direction phrase in second language teaching.It includes reasonable arrangement of teaching order,optimizing Chinese textbook compilation;the interpretation of specific methods,methods of practice and teaching of verb-direction phrase. |
