This book is really good! It explains grammar knowledge in a simple and easy-to-understand manner, and the analysis of example sentences and table illustrations in the book are also very clear, making it easy to understand at a glance. I particularly like the way it organizes the knowledge points, which is very organized and makes it easy for me to learn. And the author is very considerate from the perspective of our readers. In short, this is a very practical English grammar book, I like it very much!
