| Chinese grammar is the focus of Chinese learners’ learning and teaching.How to arrange grammar points in textbooks in a scientific and objective way has always been a hot topic in academic research.In 2021,Chinese Proficiency Grading Standard(here in after referred to as Level Standard)will be issued and implemented,providing an important reference for the arrangement of Chinese textbooks and Chinese teaching.This paper takes the grammar contents of Developing Chinese · Elementary Comprehensive Course,which are widely used and influential,as the research object.Through the literature research method,statistical analysis method and comparative analysis method,the paper analyzes the selection of grammar point in the textbook.It also makes a statistical analysis of the outline of grammar grades in Level Standard,to clarify which grammar points are included in the textbook but not in Level Standard,and which are included in Level Standard but not in the textbook.Then,based on the retrieval results of interlanguage corpus,it is determined which grammar points should be included in the textbook according to the difficulties of learners.The research findings of this paper are as follows:(1)The distribution of grammar points in Developing Chinese · Elementary Comprehensive Course is reasonable,and the average number of grammar points in each unit is between 3 and 4,and the difficulty arrangement basically follows the principle of step by step;(2)Only about 49% of grammar points in the textbook coincide with those in Level Standard.In the textbook,"first...Then 47 grammar points such as ","etc.are not included in the Level Standard,while 61 grammar points such as the wish verb "dare" in the Level Standard are not included;(3)According to the retrieval results of interlanguage corpus,49 grammar points without overlap are difficult for learners.The research suggestions:(1)The "Although" the 17 grammar points such as "just" are not in the Level Standard,they should be kept in the textbook because they are difficult for learners.(2)There are 32 grammar points,such as "dare",which are included in Level Standard but not included in textbooks.The error rate of true learners is relatively high,which needs to be supplemented in future teaching and textbook compilation. |
