I think it is good to have a complete understanding of middle school textbooks. I used to use this book a lot. I think the textbook is so bad. You must learn the essence and read the knowledge in this book again and again. You will feel suddenly enlightened and good luck! ! ! ! ! ! The reason for this is the following：

1. Strive to consolidate the basic knowledge. The examination of basic knowledge, basic skills and basic methods constitutes the backbone of the test questions. When learning, we should understand the process of knowledge generation and formation, master key knowledge, use it flexibly, and extend the study of textbook examples and exercises. We should be good at summarizing the network structure between knowledge points and attach importance to the intersection of knowledge networks.

2. Math proposition of senior high school entrance examination is good at constructing learning model, and pays more and more attention to examining students' application consciousness. These application questions integrate mathematical knowledge into real life with interesting and novel backgrounds, and become a highlight of the senior high school entrance examination. However, these application problems have become the learning difficulties for students. Therefore, you should read and examine the questions patiently, accurately absorb the information in the questions, process and refine them, and turn them into mathematical problems in order to solve them accurately.

3. Pay attention to inquiry learning. Among the senior high school entrance examination questions, interdisciplinary comprehensive questions have attracted more and more attention. You should carry out autonomous learning based on inquiry. Gradually cultivate your own ability of exploration and innovation. When solving math problems at ordinary times, pay attention to collecting new information for processing and refining, and turn it into math problems, so as to solve them accurately.

4. Understand mathematical ideas and methods. Mathematical ideas and methods are implicit in the generation and development of mathematical knowledge. In learning, we should be good at understanding common mathematical ideas and methods, and use them to guide solving problems according to specific problems. In the ninth grade mathematics study, if you can really strengthen the cultivation of the above four abilities and improve your mathematics literacy, you will achieve excellent results in the senior high school entrance examination and realize your dream of becoming a talent.
