| Punctuation marks have a long history,and the study of punctuation marks has never been broken.Punctuation has an important influence on sentences and passages,from the extent to the extent that it changes meaning.The second period of primary school is the beginning and the key stage of primary school students’ entry into the homework.It also lays the foundation for the correct use of punctuation marks in the homework.It is particularly important to study the types,causes and corrective Suggestions of the irregular use of punctuation marks in the second paragraph.The article is divided into six parts.The introduction mainly explains the reason,significance,literature review,research methods and thinking,etc.The main part is to summarize the types and causes of the irregular use of punctuation marks in the second paragraph,and put forward some Suggestions.In the end,the research is summarized.In the second paragraph,students’ irregular use of punctuation in their homework is mainly based on A case study of Mianyang A Primary School.Text analysis is used to classify the irregular use of punctuation into four categories,and then combined with the interviews with teachers,the causes are studied and relevant Suggestions are put forward.The results show that students in the second period of primary school have prominent problems in the two categories of "unclear punctuation function" and "irregular punctuation in composition".In the category of "unclear function of punctuation marks",two minor problems are more serious,namely "wrong use of comma and period" and "wrong use of semicolon and comma".The author makes an attribution analysis on the research from both internal and external aspects.The internal reasons are mainly that the students are not clear about the function of punctuation marks,and the students use wrong punctuation marks carelessly.The external reasons are the environment in which students learn punctuation in their exercises and the improper methods of teachers in the teaching of punctuation.In the end,this study puts forward Suggestions from four aspects: improving the feasible strategies of teachers’ punctuation teaching in writing exercises,enhancing the awareness of the standardized use of punctuation in written expressions of primary school students,attaching importance to the use of punctuation in writing exercises,and strengthening the cognition and training of students’ language sense. |
