Wonders teaching material is a set of teaching materials developed for children in English-speaking countries, which is completely written according to the cognitive way of mother tongue thinking. Therefore, there will be some problems when domestic children use the original textbook Wonders. For example, Mr. Peanut found that the teaching materials of wonders had a good effect in the early stage, and there would be a sense of fault in the later stage.

Because American children have a good foundation in English, many simple words are not taught later, so they are skipped directly. Children with poor domestic foundations will inevitably feel that they can't keep up.

WonderSkills textbook is specially developed for second language learners. 70% of the content in WonderSkills comes from Wonders. The theme is the same as the picture, but the text is less difficult. At the same time, some textbooks and exercises suitable for domestic children have been added, which are more in line with the actual English level and study habits of Chinese students.
