This paper analyzes the present situation of middle school students' oral English learning from the aspects of middle school students' oral English learning, English teachers' quality and teaching environment, and puts forward corresponding solutions and ways to improve their oral English expression ability. Paper Keywords: optimization strategy of oral English teaching in middle schools The new curriculum standard puts the cultivation of language skills in a prominent position. The purpose of English teaching is to "pay attention to practicality and aim at application", and cultivate technical application-oriented talents with certain international adaptability and strong innovative spirit and ability. With the in-depth development of English education reform, oral English is an important part of English listening, speaking, reading and writing ability. In English education, it can not only promote the development of listening teaching, but also improve students' reading ability. First, the current situation of middle school students' oral English learning 1. student Middle school students have a strong perception of their mother tongue, and it is difficult for many students to get rid of their mother tongue thinking mode, so Chinglish often appears. In English learning, students often sit and listen to the teacher's explanation in class, which makes it difficult for students to speak and improve their oral English effectively. 2. Teachers. At present, a large number of teachers in many schools lack the concept of re-learning and training and refuse to explore advanced teaching models. The concept of oral English teaching still stays in the past, and even some teachers have a strong native accent. They attach importance to knowledge transmission and neglect ability training. In teaching, they just instill knowledge into students, but seldom cultivate their oral English expression ability. 3. Teaching environment. At present, the tendency of exam-oriented education is serious, and many schools' oral English is not within the scope of examination. In order to improve the enrollment rate, schools have neglected oral English learning, and oral English teaching has obviously not been taken seriously. Second, the cultivation of middle school students' oral English ability 1. Encourage openness and improve self-confidence. "I like losing face!" This is a famous saying in Crazy English. In English teaching class, students should be the main body of learning, not the passive recipients of a lot of knowledge. Teachers should pay attention to encouraging students in more ways. Some students' oral pronunciation is a little poor, so try not to have too many blows, encourage students to speak, and improve their enthusiasm and confidence in learning oral English in various forms of activities. In a class group, students' learning ability cannot be the same. Therefore, teachers should adopt different teaching methods according to students' personality differences and their ability to accept knowledge. For example, introverted personality, nonstandard English pronunciation, poor basic level of oral English, unwilling or afraid to speak at ordinary times, and even some students have fear. Teachers should first do a good job in students' psychological work, find a suitable time for students to speak English alone, practice from simple words, and praise them in time if they find good or standard words. In the past, they will gradually help students build confidence and improve their oral English training to some extent. As an English teacher, in addition to teaching English theory, the author thinks that more attention should be paid to improving students' oral English communication ability. In teaching, we should not only pay attention to the presentation of oral English ability in class, but also pay attention to oral communication outside class. The input and output of these two channels are cyclical, and students' oral English ability can be improved through the linkage of in-class and extracurricular activities. 3. Optimize the oral English learning environment. Oral English teaching is essentially skill teaching. In order to make students gain lasting interest, teachers and students are required to create a good English atmosphere after class. In English teaching, in addition to normal classroom teaching, teachers should organize extra-curricular activities to create more English-speaking environment for students, such as opening up English corners, English lectures, English speech contests, English knowledge contests, English sketch contests, English song contests, English dubbing contests, and English movie appreciation. In addition, a certain number of English famous sayings and aphorisms can be set in teaching buildings, lawns and main roads inside and outside the school, so that English teaching in the whole campus environment can be continuously upgraded and optimized. By optimizing the whole campus environment to infect or influence students' oral English learning, students can have a good English learning environment, which can not only facilitate students' English communication, but also improve their oral English expression ability. Third, strengthen the construction of oral English learning environment 1. Strengthening oral English teaching by using multimedia network technology. With the development of computer network information technology, English education can make full use of modern science and technology, show students relevant videos of oral English teaching and ask students to have a dialogue, which can play a positive role in improving the efficiency and effect of oral English teaching. Multimedia and network technology combine words, sounds, images, animations, audio and video signals, which can provide real language materials and vivid language communication scenes, making students seem to study in a rich language environment. Teachers can use multimedia teaching equipment, simple English movies, songs and speeches to create a real language environment for students, so that students can learn authentic pronunciation and intonation, thus improving their oral English ability. 2. Build an assessment system of oral English ability. At present, many middle schools do not have a systematic oral English evaluation system. The usual practice is to add a listening test to the final exam or senior high school entrance examination, and there is no separate arrangement and requirement for students' oral exam, which is easy to cause students who are used to exam-oriented education to ignore oral learning. In oral English teaching, an imperfect evaluation system will have a great impact on oral English teaching. Therefore, it is necessary for schools to refer to some practices of schools at home and abroad when building an evaluation system of oral English ability. For example, the sharing of resources between schools is conducive to improving the evaluation system of oral English ability. In short, the cultivation of middle school students' oral English ability is not achieved overnight, and it needs a gradual cultivation process and scientific and reasonable teaching methods. Teachers should change the traditional teaching mode, use oral English in class and express it in real communication, so that students' oral English ability can be effectively improved.
