| The sentence pattern "Ning Ke … … Ye … … " occupies an important position in modern Chinese,and it appears and is used frequently in modern spoken Chinese.To some extent,it can be used as a standard to measure the Chinese level of foreign students in teaching Chinese as a foreign language.Generally speaking,Chinese students can understand and use this sentence correctly by virtue of their sense of language,but foreign students often make many mistakes in acquiring this sentence,which makes it difficult to master it correctly.Many sages have studied the sentence pattern of "Ning Ke……Ye……" from the perspectives of semantics,pragmatics and discourse,but their views are still inconsistent in some aspects.Therefore,based on the research of sages,the grammaticalization of "Ning Ke" is investigated,and from the perspective of construction,based on cognitive grammar and construction theory,the semantic features of components "Ning Ke" and "Ye" of "Ning Ke……Ye……" and variable components A and B are described and analyzed,and the relationship between variable components is also investigated.Furthermore,the corpus is collected and the corresponding questionnaire is designed.The survey results show that foreign students’ acquisition of the construction "Ning Ke……Ye……" presents their own characteristics according to different grades.In addition,according to the analysis of errors and the summary of errors,the teaching process is designed by stages,which provides a new perspective for second language acquisition and teaching. |
