Foreign language education experts generally believe that there are three main disadvantages of "early foreign language education": first, from the perspective of foreign language education theory, "early foreign language education" may have some cross-language negative effects on children's pinyin learning and vocabulary acquisition, in addition to occupying the absolute space and time of mother tongue learning. Secondly, from the empirical study of foreign language education, the critical period hypothesis supporting "early foreign language education" has not been supported by convincing experimental data; However, the comparison between "early foreign language teaching" and "late foreign language teaching" has not been verified by classroom teaching experiments. Thirdly, from the perspective of the application prospect of foreign language learners after mastering foreign language skills, if learners fail to go abroad or engage in foreign language-related work, the foreign language skills they have mastered through diligent study and hard study will obviously decline with the passage of years, that is, "foreign language abrasion".

The Foreign Language Teaching Committee, under the leadership of the Ministry of Education, conducts research, consultation, guidance and service on the education and teaching work of relevant majors and fields of vocational education, and is also an expert organization that guides the training work of relevant majors and fields of vocational education.

Understanding the essence of language teaching and the function of language teaching methods, and thinking about the objectives of language learning, the principles of task design and the principles of effective classroom teaching can position the role of teachers in the process of language learning.
