Excellent children's English reading books can effectively grasp the critical period of children's language intelligence development (3-6 years old). At this stage, the child's pronunciation organs gradually mature and begin to master the pronunciation and intonation. Moreover, preschool children have keen hearing, strong imitation ability, strong mechanical memory, small psychological barriers and curiosity about new things outside. During this period, English learning textbooks combine children's logical order of learning English, fully tap children's potential of learning English, and stimulate children's interest with classic rhythms and ballads. Moreover, because the rhythm and songs are colorful and catchy, it is more conducive to children to master English learning skills imperceptibly in a relaxed learning atmosphere.

The theme of teaching materials should be based on the short stories and ballads of small animals' daily life that children are familiar with, from easy to difficult, so that children can understand the pronunciation and semantics of English in entertainment and integrate English learning activities with other learning and living activities. For example, children's English textbooks are mainly based on western classic rhythms and small ballads that children are familiar with, and each text is accompanied by vivid illustrations, which are consistent with the content of the text to help children understand the text; In the classroom, not only singing and playing games, but through the application of appropriate teaching methods, children can be truly inspired to realize effective English learning and achieve the goal of cultivating their comprehensive ability.
