The textbook is completely answered, summarizing all the important knowledge points in the high school textbook, and equipped with corresponding typical exercises, which can lay a solid foundation.

"Five-year college entrance examination, three-year simulation" focuses on the original questions of college entrance examination papers all over the country, and is equipped with detailed analysis flow, so that students can sort out the ideas of high school mathematics problems, be familiar with the general questions of college entrance examination and improve their problem-solving ability.

Tian Li's Thirty-eight Episodes, which is based on the topic, contains a large number of mathematical problems with quality and worth explaining, which can improve students' problem-solving thinking ability and logical thinking ability.

Because senior one and senior two are still learning new lessons, we must choose synchronous teaching AIDS for preview or study. The so-called synchronous class is one-to-one correspondence with teaching materials and courses, and it is also divided into explanation classes and practice classes. Among them, the famous explanation is "Complete Interpretation of Textbooks", which is a representative teaching aid for detailed analysis of textbooks.

It has a publishing history of nearly 20 years. To be exact, the word "interpretation" was first popularized by it. Its writing logic is that there is a "Xueba Notes" in front of the book, which summarizes the knowledge structure system of the book.

The first lesson is completely in line with the textbook. Each chapter is progressive according to test sites, test methods, test skills, test sites and test ability, corresponding to the interpretation of knowledge points, detailed explanation of test sites, test skills, easy-to-miss points, practical training, from understanding to problem-solving skills to problem-solving practice. It is characterized by comprehensiveness, or how to call it a "complete explanation"

Compare examples to make it easier for students to understand. This point was learned in many teaching AIDS, including textbooks. However, it is very difficult to give examples one by one, involving many aspects such as topic selection. Many people only learn its shape, not its essence.
