The first point: in terms of methods, we should "protect the strong and restrain the weak" and promote the balance of disciplines. Everyone has different characteristics. Some students are good at these subjects, while others are good at those subjects. Everyone has a relatively weak subject to some extent. For this problem, we should adhere to the policy of "protecting the strong and weakening the weak", consolidate the dominant disciplines, improve the weak disciplines, give full play to the potential of each discipline and realize the optimal combination. You can't dislike a subject because of its weakness, and you must never lose interest because of disgust. Without interest, if you don't learn well, you will fall into a vicious circle. It is necessary to increase investment in "weaknesses" and ensure quantitative contact every day, but this process is very difficult. Some students will say, "Oh, it's really annoying. I have memorized English for several days. How can a cloze have so many mistakes? " Oh, what is it? I have done a math test paper for more than ten times every day, but I still don't know how to test it. "In other words, in the" weakening "investment, it is more important to persist for a long time. After the quantitative change has accumulated to a certain extent, the progress will be obvious." There are some problems to be paid attention to in strengthening and weakening, which should meet the specific requirements of Grade Two. It is also a place where the college entrance examination is easy to distance, so it is necessary to comprehensively improve the learning level of Chinese, mathematics and foreign languages during the second year of high school. By the way, the learning methods of some subjects should be discussed according to their own situation. Mathematics learning focuses on cultivating thinking and training understanding ability. It is reasonable to say that we should not agree with the "sea tactics", but in fact, the more we do this, the firmer we grasp the basic methods, and the more we respond to related problems, the better. Therefore, "multi" should be based on "precision", which means not only spending time on new and typical questions, but also choosing good ones. Good questions are unbiased, including important knowledge points, and many other issues can be corrected. The probability of encountering the original question in the college entrance examination is almost zero, so the purpose of doing the question must be clear, not to touch the question, but to improve one's logical reasoning ability and analytical comprehensive ability. Only in this way can you have a broad feeling when you take the exam to solve a problem. A teacher once said, "The result of a question is worthless. What matters is the formation of ideas, the choice of methods and the thinking after the question. "Post-question reflection is very important, and there are many contents of reflection, such as how to change principles, methods and questions. It should be noted that unclear questions must not be let go and must not be missed when thinking about some problems. A red-faced argument between classmates can lead to a new idea, and the teacher's words often "wake up the dreamer". I did so, so I got a high score of 138 in the college entrance examination. A prominent feature of geography study is that I attach great importance to maps and charts. I want to put my knowledge into the map and build a sense of space. When I talk about a place in the world, I should immediately expand a map of the world, and then that place seems to be there. The geographical features, climate, natural conditions and cultural landscape of that place should also be reflected immediately. This can not only be a good memory, but also help to understand deeply. Second, regarding the effect, we should study hard and pay attention to efficiency. Some students say that diligence equals clumsiness, which is an extremely terrible idea. Practice has proved that a diligent person is smart, because he knows the importance of diligence, and he knows that he will succeed in the college entrance examination if he works hard now. Learning more knowledge will make you more competitive in your future study and work and realize the value of life. Those who laugh and laugh under the eyes of others all day, don't study hard, and even affect others' study, and think they are smart, can't be said to be smart. They don't even understand the basic principle of cherishing the good time of study, how can they say they are smart? So diligence is rare, diligence is very important, and diligent people are noble. Not only be diligent, but also be efficient. Although many people don't feel this sentence now, I think I am still ahead of the times. The speed of solving problems is the most important thing to win the college entrance examination. We should do something as soon as possible, so as to gain more time, preview new content and review what has been said. In this way, we will have a strong sense of relaxation and superiority, and we will definitely show our superiority in the college entrance examination. The third point: about. Keep a healthy mind. Strength is the foundation and mentality is the guarantee. It is necessary to eliminate unhealthy psychological barriers, exercise the ability to resist setbacks and pressure, be lively, cheerful and optimistic, and cultivate good psychological quality. During the transition period of senior two, I was worried about choosing articles and theories, and later I chose liberal arts. I don't know if I chose the right one. When the exam is not going well, the mood fluctuates greatly, and the mood fluctuates greatly. Causing unnecessary losses. In the second year of senior high school, whoever completes the transition of different subjects first adjusts his mentality will win quickly. Since you have chosen, you should not regret it. He should be prepared to bear hardships and work hard with his feet on the ground. If the exam doesn't go well, it will affect his mood more or less, but he should hint at himself and adjust himself. Students should encourage each other and make progress together. In short, he should. To promote the balanced development of all subjects, we should study hard, pay attention to efficiency, cherish time and maintain a lively, cheerful and optimistic healthy psychology. Senior two is a critical period for senior three, which not only has a heavy course task, but also largely determines the future development direction of students and whether they can be admitted to an ideal university. Teachers with rich teaching experience will teach you the learning skills of senior two subjects, hoping to let senior two students master good learning methods. Help to improve learning efficiency. Combining Chinese with the syllabus, Li Yuefeng (the head of the Chinese teaching and research group in Nan 'an No.1 Middle School and the head of the Chinese preparation group in Senior Two) clarified the teaching content and requirements. The syllabus divides the "teaching content and requirements" of senior high school Chinese into reading, writing, oral communication and comprehensive learning. These ability goals are all achieved in three years of high school study. Senior two is the continuation and extension of senior one's study and the further development of our ability. Therefore, we need to further strengthen reading, expand reading scope, understand in reading and improve reading ability. These texts should be carefully studied and read, and the learning contents and methods in the third volume are specific. My personal opinion is that in the part of "Reading Classical Chinese", we should carefully study the eight texts of the two selected units, which is the premise of forming reading ability. The classical Chinese knowledge involved in this paper, such as common words, ancient and modern different meanings, polysemy, flexible use of parts of speech, special sentence patterns and fixed sentence patterns, should be classified and accumulated under the guidance of teachers. The sense of language in classical Chinese can also be formed through repeated reading, so it is expected to form an ability to read after class and achieve the effect of "drawing inferences from others". The articles selected in The Reader are auxiliary materials. This is a good model to test reading ability. We should read carefully, enter the emotional world of the ancients and understand their humanistic feelings. As far as poetry appreciation is concerned, we should grasp the characteristics of China's poetry. China's poems pay attention to the creation of artistic conception, and show the life picture through the combination of images, thus conveying the poet's aesthetic experience. Therefore, it is very important to grasp the image when reading poetry, and you can grasp the artistic conception under the guidance of the teacher. Master the basic essentials of reading poetry, be familiar with the expressive skills of poetry, so as to achieve the purpose of appreciation, which is also achieved through a lot of reading accumulation, repeated reading and careful mastery. As we all know, "You can recite poems by reading 300 Tang poems", which shows the importance and necessity of repeated reading. Reading is the basis of reading poetry; If you don't recite a poem, you don't read it. You must know something if you can recite it.

Mathematics focuses on cultivating the ability of observation, analysis and reasoning. Chen Jianshe (an interest group counselor in Nan 'an No.1 Middle School) cultivated a strong interest. High school mathematics has abstract concepts, many exercises and high teaching density. Therefore, after the first year of high school, some students are afraid of mathematics. In fact, it is not difficult to learn mathematics. The key is whether you are willing to try. When you dare to guess, it shows that you have mathematical thinking ability; And when you can verify the conjecture, it means that you have a talent for learning mathematics! Seriously study senior two mathematics, what you can understand is: how to make objects that meet the requirements with the least materials; How to allocate resources and put them into production to get the maximum profit; Why beautiful curves can be associated with algebraic equations; Why it is much easier to have a car accident than to win the sports lottery; Why do students with the same birthday often appear in all classes in a year … When you fall into the trap of mathematical charm, you have taken the first step to learn mathematics well! Cultivate the ability of analysis and reasoning. In fact, mathematics is not a knowledge-based and empirical subject, but a thinking subject, which has been fully reflected in senior high school mathematics. Therefore, mathematics learning focuses on cultivating the ability of observation, analysis and reasoning, and developing learners' creativity and innovative thinking. So in the process of learning mathematics, we should consciously cultivate these abilities. The relationship between learning methods and results can be described as follows: when you are willing to understand most of the topics, when you are keen on studying various types of questions and making regular summaries, you must be an excellent student in class mathematics; And when you are used to doing your own problems and solving them according to the definition of mathematics, your mathematics level can already keep pace with the teacher! Try these learning methods. Students with different learning levels need different learning methods. If you are troubled by the low state of mathematics learning, please follow the following requirements: after previewing, you can get twice the result with half the effort by coming into the classroom with questions; Doing beautiful homework is ignorance, and it is more reasonable to make serious corrections if you do something wrong; The exercise required by the teacher is not a "sea of questions". Please finish it carefully. If there is a genius who can learn math well with fewer words, it is not you. In the exam, the correct rate is as important as the speed of doing the questions, but giving up some questions reasonably can help you play your normal level. If you are depressed because of your slow progress in math, please accept the following suggestions: collect the wrong questions you have done, correct and write down the reasons for the mistakes, which belong to your personal wealth; For exam results, set yourself an acceptable bottom line and a goal within your power; Reasonable schedule and good study habits will help you get stable academic performance, so please make a good study plan and stick to it; Put a lot of time on one subject, it is better to allocate learning energy to each subject reasonably. When people study knowledge in a certain field, there is often a "plateau phenomenon", that is, when they reach a certain level and study hard, the progress begins to be inconspicuous. History pays attention to the systematicness and integrity of knowledge. Ye Yulin (leader of history teaching and research group in Nan 'an No.1 Middle School), a senior high school teacher pays attention to the application of comparative learning methods. The modern history of the world is not only clear in stages, but also very clear in several clues. That is, the development of capitalism, bourgeois revolution or reform movement, bourgeois ideological movement, colonial expansion, socialist movement and national independence movement basically involve all stages. Pay attention to comparison, induction and generalization when studying. Find out their similarities and differences. For example, the bourgeois revolution or reform movement includes the bourgeois revolution in the early 8th century (Britain, France and the United States), the European revolution in 1848 and the bourgeois revolution and reform in the 1960s and 1970s in 19. The same reason of revolution in different stages is the development of capitalism. However, the different development degree of capitalism determines the specific reasons of bourgeois revolution in different periods, and the fundamental tasks, processes, endings and influences of the revolution are very different. Another example is humanism, rationalism, liberalism and other progressive ideological trends in the ideological field. They have the same or similar reasons, ideas and properties, but these ideological trends in different stages have their own specific ideas. The role and influence of history are very different. When studying, we can better master historical knowledge, understand the law of historical development and improve learning efficiency by vertically connecting, comparing and summarizing some related historical events. As students of liberal arts classes, they should base themselves on the college entrance examination from the second year of high school and pay attention to the systematization and integrity of knowledge. Fine print and illustrations complement the text. Study should be closely combined. We should also have a comprehensive understanding of the reading class stipulated in the textbook, especially some important chapters and knowledge points in the knowledge system can not be ignored. For example, the fourth quarter of Chapter I-Religious Reform on the religious reform in Britain, the second quarter of Chapter II-the reform of feudal countries in Europe, the third quarter-the colonial expansion of western European countries, and the third quarter-/kloc-Europe in the early 9th century and 1848 revolution. Only by mastering these contents can we form a systematic knowledge structure. History also has the skill of "memorizing". Paying attention to the combination of Chinese and foreign history and China's modern history is a part of modern world history. When studying the modern history of the world, we should contact the relevant knowledge of the modern history of China. If we study "the initial formation of the capitalist world market" or "the Asian revolutionary storm", we can link the Opium War with the Taiping Heavenly Kingdom Movement, and have a further understanding of the historical background, the influence of the two opium wars and the status of the Taiping Heavenly Kingdom Movement. Studying the "European Enlightenment", we can contact the "Revolution of 1911" and the "New Culture Movement" to understand the influence of western bourgeois ideas on the China Revolution; The study of Industrial Revolution and Capitalist Economic Development can be linked with China's Westernization Movement and the Rise of China's National Industry, which can help us to have a better understanding of the beginning, process and characteristics of China's industrialization. Through the contact and comparison of Chinese and foreign history, we can not only broaden our knowledge, but also speed up the mastery of the relevant knowledge of China's modern history. Organically combine Chinese and foreign history. English should pay attention to the cultivation of ability. Wang Chunbo, an English teacher in Senior Two of Nan 'an No.1 Middle School, should pay attention to the cultivation of ability. Senior two English requires students' listening, speaking, reading and writing skills. Generally speaking, senior two English should pay attention to the cultivation of ability, so as to lay a solid foundation for future communication and further self-study. In my opinion, laying a good foundation is the premise of learning English well. How to lay a solid foundation? Preview before class to find out the difficulties; Listen attentively in class and consolidate; Review in time to prevent forgetting; Independent work test effect; Classify mistakes and solve problems; Practice hard and read widely; Summarize and master the law systematically. Create an error file. In the process of learning, the acquired knowledge and skills will have a certain impact on the formation of new knowledge and skills in the future. The best way is to eliminate mistakes and acquire correct knowledge and skills. After each exercise or exam, you should copy down the representative questions you made wrong, collect them, and then recite the correct sentences and keep the wrong answers after the teacher explains the mistakes. Write the correct answers in red pen and criticize the reasons, thus forming new language habits. Reading at ordinary times and before the exam will deepen the impression, attract attention and greatly reduce the error rate. It not only consolidated knowledge, but also improved the ability to take exams and played the best level. Emphasizing the cultivation of reading comprehension ability aims at improving the overall understanding and reasoning ability of the text. The ability to summarize. Persisting in long-term reading (at least two articles a day) is the guarantee of steady improvement. Through planned and step-by-step extracurricular reading (such as reading the English version of 2 1 century middle school students' newspaper, the second and third volumes of New Concept English and the synchronous tutoring, listening, speaking, reading and writing version of English Weekly), we can not only consolidate and broaden the content of textbooks, but more importantly, make knowledge come alive. Stimulate a strong interest in learning English and a desire to expand knowledge. Develop the habit of reading and reciting. Reading is a comprehensive practice of basic knowledge such as pronunciation, intonation, meaning groups and sentence patterns in the context provided by the text, and at the same time, it cultivates pure pronunciation and intonation and good language habits, laying a solid foundation for listening. Read and recite the learned sentence patterns, phrases, dialogues and texts, form a fluent sense of language, cultivate understanding ability and lay a good foundation for oral English, reading and English writing. & gt& gt& gt The teacher of Beijing No.4 Middle School said that it is also important to practice and recite English sprints more to develop good writing habits, and it is also important to develop the habits of standard writing, neat handwriting and neat paper. A considerable number of students in senior high school are illegible, careless about case and spacing, and the indiscriminate use of punctuation marks will bring great trouble to teachers in correcting homework and test papers. This will lead to a great loss in marking the college entrance examination. Senior two students should form the habit of writing norms, be meticulous in case, punctuation and word spacing, and strive to be standardized, neat and beautiful. They need to replenish their vocabulary if they want to get into the habit of using English-Chinese bilingual dictionaries. Students should prepare an English-Chinese dictionary, such as Oxford Advanced English-Chinese Dictionary, which can solve students' doubts and help them understand the usage of words to a great extent. The vocabulary is constantly expanding. Politics firmly grasps knowledge points and integrates theory with practice. Huang (leader of political lesson preparation for senior two in Nan 'an No.1 Middle School, a middle school teacher) accurately understands the basic concepts, pays more attention to the cultivation of subject ability and emphasizes the examination of thinking ability. So there is a misunderstanding among some teachers and students that basic knowledge is not important. In fact, knowledge and ability are unified. Knowledge is the carrier of ability, and ability is the application of knowledge. Ignoring basic knowledge and unilaterally emphasizing ability will make ability a tower of sand dunes. Compared with the economic common sense of senior one, the concepts and principles of philosophical common sense of senior two are more abstract and more difficult to understand, so we should pay special attention to the memory, comparison and understanding of these concepts and principles, such as the material and consciousness of the first lesson, objective reality and objective existence, subjective and objective. For example, in the third lesson, we should carefully compare, understand and remember these confusing concepts and principles. When answering questions, you should master the knowledge accurately and meet the requirements. Some keywords and words should be completely consistent with the teaching materials, and mistakes should not be made at will, such as "objective existence" in the concept of matter and "internal, essential and inevitable connection" in the concept of law. Many mistakes in the exam can be avoided. Recycle review and do more exercises in politics, history and geography, all of which require a lot of memory. According to the law of memory forgetting, students should not only preview before class, but also listen carefully after class. The textbook can be divided into several stages or parts. After learning from the teacher to a certain stage, you should return to the first stage in time and review according to your own plan. Cyclic review is good for memory. Get twice the result with half the effort. Do more exercises and standardize the answers. Point-by-point, segmented, clear and standardized subject terms answer political subjective questions, combining principles with materials. To this end, students should do more exercises besides listening carefully and memorizing and understanding. As the saying goes, practice makes perfect. >>& gt& gt Political review should integrate theory with practice, adhere to the principle of integrating theory with practice, and correctly handle social hot issues that people care about. This is the inherent requirement of political course and an important principle of political college entrance examination proposition. Therefore, learning philosophical common sense should combine abstract philosophical principles with the reality of social life. By doing so, we can not only further understand the philosophical principles, but also use the principles to analyze social hot issues and improve our ability to analyze exams. The particularity of contradiction requires concrete analysis of specific problems; Look at the problem from the perspective of connection; Principles such as the relationship between quantitative change and qualitative change can be combined. Teaching practice has proved that students can learn well, adapt to the requirements of the college entrance examination and achieve good results if they can skillfully connect hot issues with the principles of teaching materials and use them correctly. Geography mainly grasps several clues of human geography. Xu Yaling (leader of geography preparation group in Nan 'an No.1 Middle School and No.2 Middle School, senior middle school teacher) pays attention to the relationship between segments. The main knowledge contents of geography elective textbooks in senior high schools are concepts, influencing factors, types, laws and examples. Human geography accounts for the majority, and the proportion of physical geography is low. In the process of learning, we should grasp these knowledge clues and pay attention to the main points of knowledge, but we can't remember them in detail. At the same time, we should pay attention to the knowledge connection between the plates, such as the chapter on population, the connection and difference between population and environment, and the quality of population and environment; Another example is the relationship between urban form and reasonable urban planning, the relationship between urban functional zoning and the causes of urban functional zoning, and the relationship between cultural areas and cultural diffusion. Understanding these relationships is not only conducive to understanding, but also to the memory and application of knowledge and to grasping the key points of knowledge. Strengthening the combing of network knowledge Although there are many concepts and knowledge points in the elective textbooks of senior two, each chapter has close internal relations. This connection forms a knowledge network. By combing the network level, students can easily use what they have learned and are not easy to forget. At the same time, it is also conducive to the transfer and application of knowledge. Because the map is the knowledge carrier of geography, the principles, laws, distribution and examination methods of geography are all concentrated on the map, so if you master the knowledge on the map, you will master the backbone of knowledge. Not only can you learn how to interpret characters with maps, but you can also master the knowledge of characters from maps, which is also a good method. >>& gt& gt Zheng (the head of the physics preparation group of Grade Two in Quanzhou No.7 Middle School) completed the study task in time and entered Grade Two. Students should adjust their study time in time, and pay attention to the fact that the study tasks of the day should be completed on the same day, and no questions should be left, so that many a mickle makes a mickle. The more questions there are, the greater the pressure of study, which affects the confidence of learning physics well. High school physics knowledge system is tight and complete, and knowledge is systematic. Therefore, we should pay attention to mastering systematic knowledge and cultivating methods to study problems. Paying attention to experiments and being diligent in experimental electrical experiments is a difficult point in senior high school physics and also the content of college entrance examination. Therefore, we must learn this part well. Before doing the experiment, we must make clear the principle and steps of the experiment, pay attention to observation and do every experiment well. Students with ability can design some experiments by themselves. And go to the lab to verify. This is of great help to the improvement of experimental ability. Compared with Grade One and Grade Two, the combination of listening and self-study has more teaching content and larger classroom capacity. Students must pay attention to the teacher's explanation and keep up with the teacher's ideas. Listening carefully in class is the most direct and effective way for students to learn methods and improve their ability. In class, they should think positively and keep asking themselves questions. Then get the answer by listening to the class. To realize the high efficiency of the classroom, we must preview before class, pay attention to the connection between old and new knowledge, integrate the newly learned physical concepts and laws into the original cognitive structure model, master new knowledge quickly and transfer knowledge smoothly. Preview not only increases our understanding of relevant content, but also improves our reading comprehension and examination ability. Over time, students' self-study ability will be greatly improved. Reviewing and summarizing regularly should form a good habit of reviewing and summarizing regularly in the learning process. Review is not a simple repetition of knowledge, but a process of sublimation and improvement. First, review on the same day, which is one of the efficient and time-saving learning methods. Second, review at the end of each chapter, clarify the main line of knowledge in each chapter, master its knowledge structure, and systematize knowledge. Find the connection between chapters. Establish a new cognitive structure and knowledge system. It not only consolidated and deepened the knowledge, but also learned the methods and improved the ability. There are not many things to memorize in physics, but most of them need to be understood. Through systematic and effective review, we will find that thick physics textbooks are actually "very thin". We should try to classify the exercises we have done, find out the corresponding solutions, and change the bad learning methods, habits and psychology as soon as possible. > >； Teacher & gt& gt told you that it is very important for you to learn physics well. It is very important for you to master the "seven meetings" in chemistry. Jiang Xirong (deputy head of chemistry teaching and research group of Jinjiang Zheng Yang Middle School, middle school teacher) should know the key points of each chapter like the back of his hand. The second chapter of chemistry in senior two and the third chapter of chemical balance are important basic theoretical knowledge of chemistry in senior two, which is also the focus and difficulty of this school year. The textbook is theoretical. Abstraction is hard to understand. Only by learning these two chapters well can we better cultivate our analytical ability and problem-solving ability, realize the importance of learning chemical theory, better understand and master middle school chemistry knowledge by using chemical theory, and solve or explain some simple practical problems in chemical production and daily life. The fifth to eighth chapters are about organic chemistry, which plays an extremely important role in improving the national economy and people's living standards. Learning this knowledge well is conducive to better survival in modern society, and it is also conducive to better learning the basic knowledge of other natural sciences (such as biology) related to chemistry. Although there are many kinds of organic compounds, there are also many laws. To learn organic chemistry well, we must be good at induction and summary. In addition, to learn chemistry well in senior two, we must have "seven meetings", learn to master the textbooks of the "seven meetings", learn to learn to learn to learn to learn to learn to learn and learn to take the initiative to accept book knowledge. Preview is a necessary step in learning self-study. Learn to listen to lectures. When listening to chemistry class, you should focus on your eyes, your heart (that is, your mind is concentrated), your ears and your hands. The key is your heart, that is, use your brain, think positively and want to understand what you have learned. Learn to read. You can use the five-character reading method, that is, "read, think, ask, write and remember". So as to master new knowledge. For example, when studying the nitrogen group elements in the first chapter, we can infer their similarity and gradual change in nature according to their similarities and differences in atomic structure, and pay attention to the horizontal comparison and induction of halogen group elements and oxygen group elements learned in high school for one year, which is not only conducive to understanding new knowledge, but also conducive to consolidating the mastery of old knowledge. Learn to question. That is to say, why, look at what you have with a critical eye. To achieve a profound understanding of chemical facts, we must learn to observe things comprehensively and analyze them on this basis, so as to achieve comparison. We can ask questions, find problems, "pursue hard" and "get to the bottom of it" by "thinking backwards and finding anomalies" or "being good at comparison". We all know that chemistry belongs to science. But in the process of learning, you should feel that it has great liberal arts characteristics: much content, broken knowledge, and most of them are experimental conclusions. Remember exactly every chemical equation and the typical physical and chemical properties of each substance you have learned, remember several commonly used problem-solving methods and basic experiments, and then after some training, integrate the knowledge you have learned and finally form your ability. At the same time, you should pay special attention to the relationship between research materials and problem solving. & gt& gt& gt Seven strategies to bid farewell to poor students make chemistry leap forward. Deng (leader of biology teaching and research group in Jinjiang Middle School, senior middle school teacher and outstanding young teacher in Fujian Province) changed his concept of biology learning. For senior two students, biology teaching still belongs to "enlightenment education" in a sense. Because this year's junior high school and senior high school students' biology is not a national examination subject, nor a senior high school entrance examination subject, so many junior high school biology classes are basically going through the motions, often drawing a certain range or specifying several sets of exercises for students to remember before the final exam. Therefore, when studying biology in senior high school, students are first required to change their concepts and realize that biology in senior high school and biology in junior high school are very different in depth and breadth of knowledge. The chapters in the textbook are not completely progressive, so we may feel more abstract when we first start learning. At this time, we must not be afraid of difficulties. In order to learn biology well in senior high school, I think we should do a good job in preview, lecture, review and homework. The first chapter of senior two biology involves more knowledge of organic chemistry. At this time, students have not studied organic chemistry. Therefore, it is particularly important to preview this part of the teaching content, so as not to fall behind others from the beginning. Draw what you don't understand when you preview, and remind yourself of what you should pay special attention to in class tomorrow, so that the class will be more purposeful. Only by combining the three methods and constantly reviewing can we learn new things. Some knowledge in biology textbooks will appear in different chapters, such as knowledge about DNA, and we will introduce the compounds that make up organisms separately. The functions of various organelles are described in detail in the section on metabolism. These contents should be constantly reviewed when learning the later knowledge, and the knowledge before and after should be combined to form a knowledge network, so as to review the old and learn the new. Using charts, you are good at induction. There are a lot of charts in the textbook, so you should make good use of them when reviewing after class. For example, after learning the chapter "Cell, the basic unit of life", we can review the structure and function of each part of the cell by using the submicroscopic structure model of animal cells and the submicroscopic structure model of plant cells. In addition, we can also compare many knowledge points ourselves when reviewing, such as the comparison between mitochondria and chloroplasts, the comparison between animal and plant cell structures, the comparison between mitosis and meiosis, and so on. Apply what you have learned. Biology is a science closely related to production and life. When reviewing biological knowledge, we should pay attention to understanding the relationship between science and technology and society (STS), understand the social value of the learned knowledge, and use the learned biological knowledge to explain some phenomena and solve some problems. In recent years, the proportion of topics combining biology with practice in college entrance examination has also increased year by year.
