The introduction of quality education puts forward many new requirements for teachers and students. It requires all-round development of students, and education should be geared to all students. However, the polarization of students in English teaching is increasingly prominent. How to solve this problem? The problem of 1 is discussed around how to narrow the gap between students. Nowadays, with the development of international economic integration, English is becoming an international language. China also regards English as one of the important subjects in basic education. Nevertheless, English teaching is still far from ideal, time-consuming and inefficient, students lack confidence in learning, and polarization is becoming more and more serious. The so-called polarization phenomenon of students' English is: some students have their own learning experience and methods, learning English is easy and interesting, and their grades are good; However, some students lose interest in English learning, which leads to a vicious circle. There are many reasons for polarization. As English teachers, we should face up to the reality and take corresponding measures to prevent polarization. 2. Reasons for English polarization 1) English textbooks are more difficult, and it is required to improve [1]. In recent years, English textbooks have been revised, expanding vocabulary, updating content and increasing information. This undoubtedly increases the difficulty of teaching materials. 2) The workload of each subject is too heavy, so there is no more time for English students. They think there is a lot of homework in every class, and they can't spare more time to learn English. The characteristics of English knowledge are zero, scattered, broken and miscellaneous. The formation of English basic skills is not a day's work, but the result of long-term unremitting efforts. A little relaxation will lead to decline, and students will be tired of learning. 3) Students' mood fluctuates greatly and they are afraid of difficulties. Middle school students are in a period of physical and psychological instability, and their mood fluctuates greatly [2]. Nowadays, the psychological weakness of the only child is becoming more and more prominent: lack of perseverance, unclear life goals, relying on interest to learn, relying on likes and dislikes. These are not conducive to students' learning and growth, and are not conducive to English learning. 4) Lack of language environment Although English is getting more and more attention in China, the places where English can be used in real life are still very limited, and few parents can give guidance to their children. Therefore, the classroom is almost the only place for children to listen, speak and practice English. 3. Countermeasures to prevent polarization In order to prevent polarization and improve the quality of English teaching on a large scale, it is necessary to increase the necessary equipment, create English activity places, carry out colorful English extracurricular activities and create a strong English atmosphere. 1) Stimulate students' interest in learning, arouse their enthusiasm for learning, and create a good English learning atmosphere. Educational psychology points out that only when students are interested in something will they actively use their brains and seriously think about it, so as to acquire the most useful knowledge in the simplest and most effective way. This is thirst for knowledge! Where does the interest come from? The interest in "English ability" alone is not solid. Therefore, in order to satisfy their curiosity and desire for learning, we should insist on greeting students in English, teaching them simple daily conversations, encouraging them to speak English in class, praising and encouraging their opening remarks and small progress in time, mobilizing students' enthusiasm for learning English and stimulating their interest. 2) Treat students equally and attach importance to the efforts of underachievers and their dynamic changes. Both good students and poor students are treated equally in personality, and they do not discriminate against underachievers or spoil good students. Especially for underachievers, let them fully enjoy the joy of success through their own efforts, stimulate their interest in learning, and let them redouble their efforts to do their studies better. 3) The management teaching of primary stratified re-examination for students of different levels. The English Syllabus for Middle Schools points out: "In teaching, we should be good at studying teaching methods and adopting effective teaching methods according to the characteristics of students' physical and mental development. Teachers should face all students, teach students in accordance with their aptitude, give full play to the specialties of different students, and patiently help students with learning difficulties. Attention should be paid to helping students master correct learning methods and skills to improve learning efficiency. First of all, we should teach students in accordance with their aptitude and advocate classification so that all students can learn things at different levels [3]. For example, students with strong ability to accept English learning and potential can get rid of the involvement of students with poor foundation and become top English learners through the training of teachers; Students with poor foundation have also been paid enough attention to, and they are no longer sitting still. Through the guidance and help of teachers, they gradually master the skills of learning English. Secondly, English hierarchical teaching is one of the important means of target teaching. It puts teaching objectives into practice among students at all levels in a planned, step-by-step and measured way, which makes students gain something and teachers gain something, and helps to narrow the long-standing polarization phenomenon in English teaching. Finally, teachers should scientifically determine the teaching objectives. The level of teaching objectives should be divided into three levels: semester teaching objectives, unit teaching objectives and classroom teaching objectives: basic objectives, medium-term objectives and development objectives. The basic goal is a relatively simple part that all students can master in memory, understanding, simple application and analysis; Intermediate goal is a complicated application and analysis part that most students can master; Development goal refers to the complex analysis and comprehensive application that students with good foundation can master. For students with different foundations, teachers should adopt different methods to achieve the established teaching goals. 4) Organize extracurricular activity groups and carry out mutual assistance activities. Students with excellent English scores and good grades in other subjects are selected from the class to form a helping and teaching group, and the time after class and activity classes is used to help students with poor grades and answer various questions raised by them. 5) Cultivate students' good study habits and strong perseverance. Cultivating students' good study habits and strong perseverance can not only help them build up confidence, overcome difficulties and study effectively, but also help them persevere and be methodical in their future studies. (1) Cultivate the habit of opening your mouth. In classroom teaching, teaching methods such as questioning, teacher-student interaction, two-way communication, dialogue practice and free communication are adopted to encourage them to speak boldly, not afraid of making mistakes, and correct them if they make mistakes, so as to make progress, and at the same time let them understand that only by opening their mouths can they understand and finally get started. (2) Cultivate the habit of previewing before class and reviewing after class. Preview before class can make students know what they are doing, better grasp the key points and difficulties, find their own weaknesses, strive for the initiative in learning, and study, observe, think and solve problems with problems. After-class review can consolidate the knowledge learned in time and feed back the language knowledge points in time. Therefore, teachers should take questions, spot checks and other forms to check students' preview and review every day. (3) Cultivate students' habit of reading aloud and reciting. Use morning reading class to teach students to read English texts or play recordings for them to imitate after work every week. Doing so has a great effect on their sense of language and memorizing words. To learn English well is not to join in the fun, but to have tenacious perseverance. If you are afraid of hardship, want to be lazy and shrink from difficulties, you will never learn a foreign language well. Only perseverance can be effective. I remember Edison once said that genius is 1% inspiration and 99% sweat. If you are diligent and persistent, you can learn English well. (4) Reduce the difficulty of teaching and build confidence in success. Reducing the difficulty of teaching will help underachievers achieve relatively satisfactory results, let them feel the joy of success, let them slowly regain their interest in learning English and enhance their confidence in learning English. 4. Conclusion Practice has proved that in the process of stratified English teaching, teachers should put forward different requirements for students according to their different levels of cognitive level and learning ability, choose different teaching methods, arrange different exercises, determine different teaching focuses, stimulate students' curiosity at all levels, and mobilize their learning enthusiasm, so as to improve classroom teaching efficiency and achieve the goal of quality education. Today, it has become an inevitable trend to continue to implement quality education. It is a long-term and arduous task to face all students, make them develop actively, and prevent and narrow the polarization in teaching. However, we are convinced that as long as we attach importance to this issue and rekindle the fire of hope for underachievers as soon as possible, what we really achieve will surely turn stone into gold.
