Under the international background of globalization, China children learn English not only to enter a good school, but also to master English skills in an all-round way, so as to better cope with the fierce social competition. On the issue of how children learn English, parents should not use old ideas and old ways, but should fully grasp the following three points. First, grasp the critical period of children's language learning. About 4-5 years old is the best time to learn a second language in one's life. On the one hand, children in this period can express their needs in their mother tongue; On the other hand, it can easily imitate the standard pronunciation and is not influenced by the mother tongue thinking when learning a second language. In addition, according to professional research, the language children learn during this period will be collectively referred to by the brain as? Mother tongue? Fluent expression is very beneficial to children. Therefore, it is best for parents to start professional and systematic English teaching during this period. Second, interest is the best teacher's interest is the fundamental driving force for children to persist in learning. A strong interest in learning will make children completely immersed in the teaching process, better absorb what they have learned and improve the teaching effect. Therefore, in the process of children's English teaching, we should fully combine children's learning characteristics and hobbies, and on the basis of highly concentrating children's attention, use interactive, situational and game teaching methods to instill knowledge points. For example, senior foreign teachers in Europe and America in training institutions attach great importance to children's initiative in the teaching process, and use role-playing and scene reproduction to let children master English expression in the process of entertainment. At the same time, the teaching method of one-to-two fixed foreign teachers is adopted, and the cooperation and competition between peers are used to stimulate children's learning motivation and cultivate their awareness of internationalization. Third, applying what you have learned is the fundamental purpose of learning any knowledge, especially English. If you can't use it skillfully and accurately, it is equivalent to learning in vain. In the process of children learning English, parents can create a language environment so that children can master, understand and use knowledge points in the actual communication process. How do children learn English well? At present, some professional online children's English education institutions are doing very well in practical English education, such as training institutions and experienced foreign teachers in Europe and America to solve pronunciation and thinking problems; There are entertaining ways to stimulate children's interest; There are all English teaching settings to cultivate children's sense of pronunciation and language, so that children can learn to use it now; There is also a phased summary and review of professional Chinese teaching to strengthen the teaching effect; And the one-on-one intimate service of teaching assistants are very good choices for most parents in China.
