| The middle and high school period of primary school is the key period of students’ written language development,and students’ written language expression has changed from "writing words" to "exercise".Because the language development of students at this stage has not really reached maturity,the problem of frequent occurrence of invalid sentences in the process of writing.Through the study of bad sentences in the exercises of middle and high school students in primary schools,we can fully understand the situation and reasons of the occurrence of bad sentences in this stage,and further find out the effective coping strategies,so as to provide reference for improving the problem of bad sentences in the exercises of students.In addition,the current research on the students’ writing of bad sentences is mostly focused on the junior high school and senior high school,and there are few studies specifically on the students’ writing of bad sentences in the middle and senior high school,and the relevant theories need to be enriched.Therefore,this study has important theoretical and practical significance.In this study,the literature method was used to sort out and analyze the relevant research results,and the classification and judgment criteria of bad sentences in exercise were established.And 800 pieces of students’ exercise materials from W Primary School in Dong Chang Fu District of Liao Cheng City were selected as samples,and text analysis method was used to carry out research on them.Statistical analysis was conducted from three dimensions: the overall situation,vertical(grades)and horizontal(types of disordered sentences).Data classification and chart presentation were made for different types of disordered sentences and their distribution.Combined with the interview survey method,the causes and improvement strategies of invalid sentences are further discussed.The basic conclusions are as follows:The problem of bad sentences in the practice of middle and high school students mainly includes three categories: syntax,vocabulary and logic,and can be further divided into nine sub-categories: incomplete composition,redundant composition,disordered structure,improper word order,improper collocation,invented words,improper wording,confused logic and inconsistent.The investigation results show that the number of sick sentences in the exercises of students in middle and high schools is increasing with the increase of students’ grades,and the frequency and changing trend of different types of sick sentences are also diversified.Based on the above research results,this paper think that the elementary school in middle period of the student work pragmatically related problem is that the students themselves,teachers teaching and social language environment three dimensions a result,under the action of students in the process of language development inevitable phenomenon,take effective ways to intervene,can promote the improvement of student work.Therefore,this study puts forward coping strategies from three aspects: students,teachers and society. |
