Founded in 1928, Qidong High School, Jiangsu Province, is one of the first national model high schools and is located in Qidong City, known as "North Shanghai" with its riverside and coastal charm in the Yangtze River Delta. After eighty years of, it has become a first-class modern school in China with international influence, and its name is renowned across the nation. Qidong High School currently has 99 teaching classes and over 5,600 students. It boasts a strong faculty, including 1 Ph.D., 24 master's degree holders, 3 provincial young and middle-aged experts, nearly 100 senior and advanced-level teachers, as well as a large number of provincial and municipal subject leaders and core teachers. The school is equipped with first-class laboratories, libraries, gymnasiums, art halls, observatories, science museums, multimedia, and distance education networks, meeting students' needs for reading, training, and individual development. In recent years, the school has continuously strengthened exchanges and cooperation with other provinces and internationally, establishing 4 new branches. For many years, the school has adhered to the philosophy of "developing individual talents, promoting comprehensive development, and laying a foundation for lifelong learning," actively implementing quality education with remarkable achievements. Through long-term educational practice, Qidong High School has gradually formed a distinctive educational style: "putting people first, prioritizing moral education, solidifying foundational knowledge, and fostering individuality"; a guiding principle: "everything for the students, for all students, and for the sake of all students"; and a magical approach: "scientific education and research-driven school development." The school is advancing along the educational path of "comprehensive education and cultivating specialized talents," making steady progress and further enhancing its reputation. A group of distinguished teachers and subject leaders at Qidong High School, in addition to their teaching duties, diligently strengthen educational research and the study of middle and high school examination questions, establishing their own question bank and achieving excellent teaching results. To sincerely express gratitude to sister schools across the country and meet the aspirations of educators and students, at the kind invitation of the renowned and authoritative scientific publishing house (Longmen Bookstore), our school has organized dozens of senior and advanced-level teachers and top coaches from the frontline of teaching. Combining years of teaching experience, especially since the "3X" new college entrance examination reform and the new curriculum reform, we have meticulously planned and compiled this scientific and practical "Qidong High School Homework Series." This is the first formal collaboration between Qidong High School and a national-level publishing house, and we have specially authorized Longmen Bookstore to exclusively use our registered "Qidong High School" trademark for publication. The "Qidong High School Homework Series" jointly launched by Qidong High School and Longmen Bookstore reflects our school's teaching practices and experience in nurturing top students and addressing learning gaps. It is authentic and we believe it will be highly favored by readers.
This edition of the "Qidong High School Homework Series" has undergone careful revision. The revision is based on the new "Teaching Syllabus," "Exam Specifications," and "New Curriculum Standards." The design of the series incorporates innovation, including sub-sections such as [Preview Homework], [Classroom Homework], [After-Class Homework], and [Innovative Homework]. The revision also boldly innovates in the composition of homework questions, reflecting a fresh sense of the times, with a focus on new question intent, content structure, scenario creation, question-setting methods, and open-ended exploration. It strives to embody the new trends of the current curriculum, teaching, and examination reforms, making it more suitable for regions, schools, and students of different levels. It not only reinforces foundational knowledge but also enhances learning and exam-taking skills. During the revision, the following guiding principles and features have been fully highlighted:
1. Hierarchical and Progressive Question Structure. The questions are carefully designed to cater to the teaching realities of underdeveloped regions in central and western China and the diverse needs of teachers and students regarding "questions." Each question is marked with hollow letters (A, B, C) at the beginning to indicate its approximate difficulty level, facilitating differentiated instruction and improving the efficiency of homework practice.
2. Practical and Effective Lesson Design. The greatest difference from traditional teaching aids lies in designing homework by lesson, for synchronous classroom use. It is practical, effective, and highly operational. It integrates thinking into practice, focusing on solving the problems of "what to practice" and "how to practice" in each lesson.
3. Detailed and Standardized Explanations. The answers are thoroughly analyzed and explained, highlighting key knowledge points and basic methods, and where possible, teaching problem-solving techniques. This focuses on solving "how to do it" and "how to think about doing it," making it widely applicable. Each homework assignment is clearly marked with the time limit and scoring criteria, allowing students to practice independently ("teaching themselves without a teacher"), thereby more effectively improving the quality of their practice. Thus, this series can also be considered a student ability test book.
4. Innovative and Extraordinary Educational Philosophy. The revision fully reflects the requirements of the new curriculum and teaching reforms, embodying the educational philosophy and concepts of the new curriculum. It showcases extraordinary thinking. The selection of questions follows the principle of "originality and classics," emphasizing the development and research of "ability-based, open-ended, applied, and comprehensive" questions. Each subject's homework series includes a certain number of newly created original questions by the authors.
Judging from the "three exams" (syllabus, key points, and exam questions) and the guidance of the questions, as well as the analysis and explanation of problem-solving methods and techniques, this "Qidong High School Homework Series" is an outstanding supplementary material for students in junior and senior high schools, serving as a guide for learning, practice, and exams.
During the compilation and revision of this series, despite our efforts to review every chapter and question, and despite repeated proofreading over several months, some errors and omissions may still exist. We sincerely welcome feedback from readers to allow us to make timely corrections.
