Features: This book is written based on the new developments in junior high school textbooks and the new trends in competition, aiming to reflect three characteristics:
1. Comprehensiveness. It integrates the teaching and competition content from Grade 7 to Grade 9 in a natural and seamless manner, covering all key points in the new textbooks and the four pillars of competitions, allowing readers to achieve the effect of "having one book in hand, grasping the whole picture."
2. Synchronization. The selection and cognitive requirements of each section are carefully aligned with the teaching progress. The practice and explanation of exercises focus on patience and clarity in Grade 7, enabling readers to advance step by step on the "bridge of knowledge synchronization, ability advancement, and integrated teaching and practice," enjoying a smooth journey.
3. Layering. The format and details are designed to cater to the practical needs and future development of students at different levels. The book is structured into three layers: the first layer deepens and broadens the textbook content, the second layer focuses on the key and hot topics of the high school entrance exam, and the third layer covers the fundamental theories and basic methods of mathematical competitions. In the explanations, it adopts a low starting point with a high-level perspective—either exploring the profound background of simple problems or breaking down difficult problems into easier, solvable ones. Through this book, readers can "approach the high school entrance exam from a high perspective and the competition from a low perspective," achieving the goal of "advancing to competitions for top honors or retreating to high schools with excellent academic performance."
Although all the authors are teachers from key universities or renowned high schools, or supervisors of master's students, or hold master's degrees, whether their meticulous efforts meet expectations remains to be tested by practice.
Although all the authors have a strong interest in mathematical competitions, some are coaches of coaches or have long-term coaching experience, whether their subjective efforts yield objective results remains to be tested by practice.
