Early education must strictly follow the age characteristics of children; Otherwise, it will be counterproductive. Thinking is the core of human intelligence, which is closely related to language. The development of thinking is inseparable from the development of language. The development of children's language largely determines the success or failure of early childhood education. According to the research of child development psychologists, early childhood is a stage of rapid language development, during which children's ability to express things has been greatly improved. 1 year-old is the best time for children to actively understand the language; 2 ~ 3 years old is the best time to learn oral English; 4 ~ 5 years old is the best time to learn written language. The growth of vocabulary in early childhood is the fastest, about 3 ~ 4 times, that is, 800 ~1000 at the age of 3; 4 years old,1600 ~ 2000; 2200 ~ 3000 at the age of 5; 6 years old, 3000 ~ 4000. The development of children's language is mainly achieved through language communication with adults. Therefore, the most important task of early childhood education is to learn early childhood knowledge, pay attention to language communication with children, increase children's vocabulary and improve their ability to understand language meaning.
