In recent years, with the promulgation and implementation of the National Curriculum Standard for Compulsory Education, people's understanding of mathematics, mathematics education, mathematics learning and examination proposition is undergoing tremendous and profound changes. The new curriculum reform of mathematics has been fully rolled out and has gone deep into the classroom. Traditional teaching concepts and reform-oriented teaching requirements have had a fierce impact in the classroom. A question that people are generally concerned about is: What is our excellent tradition of teaching and learning? How to combine excellent teaching tradition with modern educational concept? Another question that people are generally concerned about is: Compared with the original senior high school entrance examination competition several years later, where is the "new" senior high school entrance examination competition under the new curriculum? What are the new features of problem conception, situation setting and problem setting? What changes have been made in the types of test questions and the focus of examination? What is the new content? How to take the exam? What is the connection with the traditional content of the original course? In order to reflect this change in time, better serve teachers' teaching and promote students' mathematical literacy, the author revised the original book from the following two aspects.

1, adjust some contents to reflect the new concept of curriculum standards; 2. Replacing more than two thirds of the exercises reflects the new trend of exam fate.
