I also think it's expensive. My son is also learning English. After studying for a semester, I will be promoted to a small class in September. My son's harvest this semester gave me a great surprise. Word baby. When I was listening to the class, I really felt that the teacher taught me very well. I learned everything well, which I couldn't teach at home. At that time, I only read those words for one semester. I was really happy when you told me how to read. I didn't expect my son to learn so much. . Before, my son studied in another kindergarten for a semester and sent some books home. He hasn't read them at all, and he won't use them to read them. But now, he likes reading very much and sends them back for review every week. .
