Features: The main content of this book focuses on "challenging questions," but this term is not limited to the last one or two questions on the exam. It has a richer connotation and more practical significance. The book selects those questions with high discrimination or a certain level of difficulty, which are the ones that significantly impact students' scores. The main content of the book is the analysis, explanation, and summary of typical examples, supplemented by an appropriate number of exercises. The examples in the book are mainly selected from recent years' Zhongkao papers and famous mock exams, with the same criteria as the aforementioned "challenging questions." These questions are crucial in exams and have the most significant impact on students taking selective exams. When students have a solid grasp of the basics, those who master this part are undoubtedly more likely to stand out in the exam! The exercises in the book are the result of the long-term and extensive research and accumulation by the authors, sharing the characteristics of "challenging questions." They are not numerous but are all high-quality, fully reflecting the direction of Gaokao question-setting. It is hoped that this can serve as a stepping stone to inspire thinking, helping readers gradually master the patterns, methods, and skills for solving similar problems, rather than simple cut-and-paste. The book's feature is its emphasis on teaching problem-solving techniques, method guidance, and pattern summaries, helping readers grasp the key to success in Gaokao, fully unleash their potential, showcase their true abilities, and achieve their aspirations. The writing of this book fully complies with the current requirements for Zhongkao review, fully reflecting the internal connections of scientific knowledge, to facilitate the improvement of readers' comprehensive abilities.
