Mathematics-Correctly apply the new theorem 1, and emphasize that understanding concepts, theorems and formulas should be memorized on the basis of understanding. Every time you learn a new theorem, first try to do an example without looking at the answer to see if you can correctly apply the new theorem; If not, compare the answers to deepen the understanding of the theorem. 2. Basic training is indispensable for learning mathematics. Usually do more exercises with moderate difficulty. Of course, don't fall into the misunderstanding of dead drilling questions, be familiar with the questions of the senior high school entrance examination, and the training should be targeted. Remembering words in English is the key. Grasping the "point" of words can drive the "line" of phrases and sentence patterns and expand the reading comprehension of articles. Words are the basis of English learning, the building materials for building an English building, and also directly affect listening, speaking, reading and writing, which restricts the ability of oral and written expression and is the basis of learning English. Remember more words, remember them firmly, use phrases and sentence patterns, read and understand articles, and cloze will be solved easily. Chinese is a long-term accumulation process. Chinese learning is a long-term accumulation process, which needs to be accumulated continuously in life and study. Therefore, you can use your spare time in life to study, see and remember a little; At the same time, accumulate some fragmentary knowledge and build your own knowledge tower inadvertently. Mr. Lu Xun is good at browsing, browsing all kinds of books, and accumulating his useful knowledge anytime and anywhere. Chinese learning must be combined with reading, thinking and writing in order to be efficient. One is that reading is accompanied by writing reading notes, writing down the most valuable contents in the book, and at the same time writing down the new ideas and new ideas in your reading; Second, keep a diary with reading and life, and record your reading experience and understanding of life. Third, reading and life are accompanied by writing articles, expressing their thoughts in concrete and standardized forms, and gradually forming their own ideological system and article style. In this way, in the long run, you can improve your Chinese listening, speaking, reading and writing skills around you, and in the distance, you can achieve your career and get married. Physics-we must strengthen memory, be good at memory and improve memory efficiency. In order to firmly remember what we have learned, we must strengthen our memory. (1) Understanding is the premise of improving memory quality. Some confusing concepts in junior middle school physics, such as "rated power", "actual power" and "specific heat", must be memorized on the basis of understanding. The law of light reflection can be compiled as: "Three lines are on the same plane, the normal is in the middle, and no matter where they come from, the angle remains the same"; The circuit logo can be written as follows: "A simple circuit has four elements, the power keys of the source line are connected in series one by one, and the bifurcation of the circuit is connected in parallel". (3) Repeated reinforcement, some knowledge is accurate and needs repeated reinforcement. In other words, when it comes to this content, we should constantly strengthen the newly formed conditional connection, use and consolidate it in time, and strengthen our memory. Chemistry-conceptual chemistry has many concepts to remember. According to Ebbinghaus's forgetting curve, the law of people's forgetting is to apply the new theorem first quickly and then slowly. So timely review and memory can get twice the result with half the effort. At the same time, pay attention to some boring and difficult chemistry knowledge and try to be interesting. For example, the sequence of metal activities is: "potassium, calcium, sodium, magnesium, aluminum, zinc, iron, tin, lead, (hydrogen), copper, mercury, silver, platinum and gold", which can be homophonic as: "The house is beautiful, and the new iron absorbs lead (light), 100 Jin." Memory. Politics-To master problem-solving methods, we must first master the basic knowledge of textbooks, learn to build knowledge systems and networks, and master knowledge from a macro perspective. It is a practical process of solving practical problems with the theory learned. In addition to the "armchair strategist" on the test paper, we should also put the work of improving our ability in peacetime and pay attention to the accumulation of knowledge and perceptual materials. Practice has proved that students with high scores in political science have a common feature, that is, a wide range of knowledge; Secondly, we should cultivate the ability to understand and analyze knowledge. Put the cultivation and improvement of knowledge understanding and application ability in peacetime, and under the guidance of teachers, consciously analyze and solve practical problems with what you have learned, not only knowing what knowledge is, but also knowing why and how. We should understand, analyze and apply knowledge at multiple levels and angles; Third, we should improve the comprehensive application ability of knowledge. We should pay attention to the construction of knowledge system, learn to analyze the same problem from different angles with multiple knowledge, and cultivate dialectical thinking and divergent thinking ability. Finally, learn the answering methods and test-taking skills. Mastering some skills of examining questions and answering questions is an important condition to improve our ability to take exams. Remembering history is the key. First, pay attention to the induction of historical test sites and lay a solid foundation. Over the years, the examination questions will be based on the outline and the outline of the senior high school entrance examination. The difficulty of the examination questions will be moderate, and the reproduction of basic historical facts is still the focus of the examination. Therefore, being familiar with or even remembering the basic historical facts will greatly reduce the consulting time and improve the speed of doing the questions. For example, the test sites of the course "British Bourgeois Revolution" can be summarized as follows: ① Revolutionary reasons ② Fuse: Scottish People's Uprising ③ Process: Time and Events ④ Bill of Rights: 1689, Content and Function ⑤ Historical significance of the revolution ⑤ Building a knowledge system of historical chapters and clearing up ideas. In order to better organize the knowledge points of each chapter systematically, we can simply build a knowledge system. For example, the process of the American War of Independence can be divided into four parts: the cause, process, result and significance of the war, and the teaching materials can be integrated, so that the thinking is clearer and more conducive to memory. Third, strengthen the induction and comparison of similar knowledge. Attention should be paid to the induction and comparison of knowledge points in history learning, such as the induction of the first international, the second international and the * * * producing international in world history; Compare the similarities and differences of bourgeois revolution in Britain, France and the United States; Comparison between Meiji Restoration in Japan and the Reform Movement of 1898 in China. Fourth, pay attention to the arrangement of key questions in each textbook, strengthen memory and improve grades. We must pay attention to certain learning methods, so as to get twice the result with half the effort.
