| Code-switching,as a teaching method,plays a very important role in foreign language class.Appropriate use of code-switching not only can ensure the smooth communication,but also can stimulate students ’learning interest,and promote the relationship between teachers and students.The study of code-switching was developed in foreign countries early,since the 1980 s,foreign language classroom code-switching became the focus of research on code-switching.Scholars,as Poplack,investigate the classroom code-switching from different perspectives with different methods.Sociolinguistics,pragmatics,pedagogics and sociocultural theory built solid foundation for code-switching.The study of teachers’ code-switching has become the focus of domestic research.However,most studies focus on colleges,universities and high schools.Very few studies were on primary stage.The author chooses “A Study on Teachers ’ English and Mongolian Code-switching in English classrooms in Mongolian Primary School” as research topic,in order to provide effective suggestions for teachers’ code-switching.Based on the current situation of the teachers ’ classroom code-switching,this thesis is aimed to answer the following three research questions:1.What are the types of English teachers ’code-switching in Mongolian primary school? 2.What are the functions of English teachers’ code-switching in Mongolian primary school? 3.What are the causal factors of English teachers’ code-switching in Mongolian primary school?
