The English foundation of rural students is very different. The classroom teaching can only focus on the middle school students. The good students can't eat enough in class and the poor students can't keep up with them. So in order to realize the all-round development, it is necessary to carry out the stratified teaching in class, so that the students of different degrees can get development. Stratified teaching is to divide the whole class into three levels, a, B and C, on the premise that the original class remains unchanged, according to the examination results and their individual psychological characteristics, learning motivation, interest, habits, ability to accept knowledge and basic level. Level a is the top students, level B is the middle students, and level C is the students with learning difficulties. Then, the teaching methods of preparing, teaching, approving, assisting and testing are implemented in different levels. After the implementation of stratified teaching, the teacher can divide the students in a class into parts, which can enhance the pertinence of teaching, facilitate the management and improve the English teaching results.
