22.At the beginning of the class you design a guessing game, what's your purpose?
Thank you for your question. In the warming up stage, I design a guessing game, because I think it can arouse students interest in learning English, my students are in grade 7 (根据所抽年级）, they're full of curiosity and competition, and they like games, so this game can better draw their attention in this class, and on the other hand, the content of the guessing game is about this lesson, which is what they will learn later, so this game can make a preparation for the further study.
