Hello, as a newly graduated college student, I want to give you some advice. I have used many teaching AIDS from primary school to junior high school. After comprehensive use, I personally feel that this book is easier to use. For example, this book has many QR codes in each class, which can be scanned by mobile phone at home, which is equivalent to teacher counseling, and there are many extracurricular knowledge supplements. Training reading methods and writing skills in actual combat can activate our thinking. The explanation next to the text is very clear, and the analysis of knowledge points makes me clear at a glance. After so many years, although my grades are not among the best, I have been in the upper middle class. In addition, if you want to do exercise books, I recommend you to use books to improve your grades. On the whole, nudging this book won't let you down.
