This book has a clear structure and combines lectures and exercises, and is intended for use by junior high school students with average grades and above. This book reasonably divides the content learned in the ninth grade of chemistry (based on curriculum standards, without distinguishing between textbook versions) into several sections. Each section is systematically and scientifically arranged in the form of test points-examples-exercises, and is specifically divided into three parts: "direct examination of test points", "intensive explanation of examples" and "passing test". Direct examination of test points: This is a summary of the test points in this section. Focused explanation of examples: The author selects typical examples and gives detailed solutions to the examples. He also writes appropriate "pointers" and "summaries" based on the actual questions. After each example, 1 to 2 questions similar to the examples are placed as "drawing inferences". Pass test: Set up 3 sets of questions, "solid foundation", "ability expansion" and "comprehensive innovation". Some of the questions are derived from high school entrance examination questions and competition questions.
Reader comments
The structure of the book is very clear, and the content is well organized, especially the "Explanation of Examples" section, which not only provides detailed solution procedures, but also provides appropriate guidance and summary, making it easy to understand and master. Moreover, each example question is followed by similar questions for consolidation, which is really practical. I think this book is a good learning material for students with average grades and above to help them better master chemistry knowledge.
