Prepare physics:

Laws are also called experimental laws. They are all laws obtained by scientists through experiments, and cannot be mathematically deduced by other physical or mathematical laws. All experimental laws of physics in senior high school should be mastered in the later experiments-the famous Galileo inclined plane experiment Newton's first law-and the famous Galileo inclined plane experiment II contains three thought experiments, which is an important test point for the college entrance examination.

Newton's Second Law In this experiment book, the experiment explores the relationship between force, mass and acceleration. Newton's third law is a simple experiment. Hooke's law is an experimental study of the elasticity and elongation of arrows. Newton's thinking and Cavendish's two torsion scales, Cavendish torsion scale and Coulomb torsion scale.

Exam chemistry:

Pay attention to reflection, standardize answers and avoid mistakes. In recent years, college entrance examination questions pay more attention to the examination of logical thinking ability, and often give conditions in the form of picture information and new terms. We need to dig out effective information from it to serve the solution of the problem. In the final sprint stage, we should pay attention to the reflection and combing of the wrong questions, especially the wrong questions in the later model test. Carefully analyze the cause of the error, and fill the gaps in time if the knowledge is unclear; If the exam is not clear, it is necessary to strengthen the exam training in the usual training.

Preparatory biology:

To lay a solid foundation, we should strengthen the teaching of the main knowledge and key contents of biology through three rounds of review. In recent years, most of the knowledge points of biology test questions come from the core content of biology, which requires us to summarize the basic facts, concepts, laws and principles of biology in the teaching materials according to the examination syllabus, build a complete knowledge network, and focus on the teaching of main knowledge.

The second round of special review adopts micro-topics and big topics, among which "basic law of heredity", "variation and breeding" and "evolution" are big topics, and the rest are micro-topics. Compared with other scientific and technological disciplines, there are more and more knowledge points in biology, and the nature of written expression is between arts and sciences. Therefore, when reviewing for the exam, we must memorize the knowledge points, because this is the basis for improving our ability, the foothold for answering questions, the form of expression and the thinking analysis tool for solving problems.
