Hello, I would like to ask which teacher is going to hand in the first book of New Concept English. Let's begin. Teacher Guo teaches the first book of New Concept English. It's good. Teacher Guo has more than 30 years of teaching experience, and has very in-depth research and teaching experience in vocabulary, grammar, reading and writing. The first New Concept English taught by Mr. Guo is easy to understand and master. Therefore, it is good to teach Mr. Guo the first book of New Concept English as soon as possible.
