Features: As this set of "Past Papers" is about to be published, as editors, we have much to say to our readers. As the saying goes, "mathematics is a gymnastic for the mind" and "a game for the intelligent." Without a doubt, various mathematics competitions—ranging from the International Mathematical Olympiad (IMO) to regional events—have nurtured countless teachers and students. The role of extracurricular mathematics activities in inspiring interest in learning and improving problem-solving skills is not optional but essential in China's basic education. It is precisely for this reason that, over the past few decades, including mathematics competitions and other extracurricular activities, have been widely welcomed and supported by teachers, students, and parents. It is well-known that the problems in these competitions are mostly set by experts and experienced teachers who specialize in the field. Therefore, in terms of quality, whether in terms of depth or flexibility in solving, they far exceed the problems students typically encounter daily. For the past papers of the "National Junior High School Mathematics League," after careful review, we have strived to provide as many practical solutions as possible to help readers broaden their thinking. For more challenging problems, we provide the original solutions, starting from the entry point, to clarify the source of the thought process, thereby achieving the effect of "generalizing from one to all." We place particular emphasis on teaching readers correct thinking methods rather than them with advanced concepts, enabling them to achieve genuine improvement.
