In language learning, children have a strong advantage to help them easily master standard pronunciation, pure language thinking and flexible application ability. However, in order to achieve this effect, parents should pay special attention to these four principles in children's English education. First, interest means that when children are interested in something, they will concentrate on listening, watching and learning, while for boring content, they will actively block it. Therefore, in children's English education, it is very important for parents to cultivate their children's strong interest in English learning. Second, the language environment creates a language environment, which brings children a lot of language input, language recognition and the cultivation of pronunciation and language sense. At the same time, the explanation of knowledge points in practical communication is conducive to cultivating children's language thinking, allowing them to apply what they have learned, so as to profoundly grasp and understand what they have learned. At this point, online children's English institutions have done very well. For example, training institutions use professional and experienced foreign teachers from Europe and America to teach English, so as to create a good and authentic language environment for children. Parents with good English level can communicate with their children in English in their daily life and cultivate their bilingual ability. Third, interesting and efficient teaching methods. Cramming education will only increase children's learning burden, and cause children's aversion and rejection of English, which is not conducive to their all-round development. In the process of children's English education, parents and teachers should carry out interesting teaching activities according to children's characteristics, so that children can acquire knowledge through entertainment, which is also conducive to children's deep memory of knowledge points. For example, on the basis of peer competition and cooperative learning, training institutions adopt interactive and situational teaching methods to improve children's learning efficiency, which is very good. Listening and speaking is the foundation of language learning. The ultimate goal of every child's English learning should be fluent communication and free expression, not proficiency in exams. Therefore, the foundation of children's English education is the cultivation of listening and speaking ability. Only by learning listening and speaking well can we teach reading and writing better.
