First, through careful study, reflection and summary, we will constantly improve our interest in science. With interest, you will easily enter the hall of science. Second, we should pay attention to the content of the teacher's lecture, so as to concentrate, be active in thinking and be diligent, that is, we should concentrate on understanding the basic concepts spoken by the teacher and deeply understand the meaning of each concept. Hurry up and sort out your own ideas and compare the teacher's answers to see what's different. If not, it is necessary to quickly judge whether it is right or wrong. If it is wrong, we must find the cause of the error. If it is the same, we can find other methods better. Third, we should pay attention to the homework left by the teacher. When doing homework, you must be diligent in thinking, take it seriously, and dig out your own methods and abilities to solve problems. Fourth, pay attention to a certain amount of exercises outside the homework. Choose the topic carefully and choose some typical topics. In the process of doing it, pay attention to multiple solutions to one problem, not just pursuing quantity. The ability to solve problems will be improved if there are more problems. Fifth, we must attach importance to the summary of science chapters, link scattered knowledge, and thoroughly understand the confusing knowledge. Sixth, if you want to learn science well and improve your interest, you must be prepared to suffer big losses, because science is a subject that focuses on understanding, and it is impossible to improve and learn science well without hard work. But I also hope that you don't have fear of science, but dare to explore and summarize a set of methods and laws to learn science well by yourself. Finally, I wish you to learn science as soon as possible and lay the foundation for learning other subjects well. Mathematics is one of the compulsory subjects, so we should study it seriously from the first day of junior high school. So, how can we learn math well? This paper introduces several methods for reference: First, pay attention to the lecture in class and review in time after class. The acceptance of new knowledge and the cultivation of mathematical ability are mainly carried out in the classroom, so we should pay attention to the learning efficiency in the classroom and seek correct learning methods. In class, you should keep up with the teacher's ideas, actively explore thinking, predict the next steps, and compare your own problem-solving ideas with what the teacher said. In particular, we should do a good job in learning basic knowledge and skills, and review them in time after class, leaving no doubt. First of all, we should recall the knowledge points the teacher said before doing various exercises, and correctly master the reasoning process of various formulas. If we are not clear, we should try our best to recall them instead of turning to the book immediately. In a sense, you should not create a learning way of asking questions if you don't understand. For some problems, because of their unclear thinking, it is difficult to solve them at the moment. Let yourself calm down and analyze the problems carefully and try to solve them by yourself. At every learning stage, we should sort out and summarize, and combine the points, lines and surfaces of knowledge into a knowledge network and bring it into our own knowledge system. Second, do more questions appropriately and develop good problem-solving habits. If you want to learn math well, it is inevitable to do more problems, and you should be familiar with the problem-solving ideas of various questions. At the beginning, we should start with the basic problems, take the exercises in the textbook as the standard, lay a good foundation repeatedly, and then find some extracurricular exercises to help broaden our thinking, improve our ability to analyze and solve problems, and master the general rules of solving problems. For some error-prone topics, you can prepare a set of wrong questions, write your own problem-solving ideas and correct problem-solving processes, and compare them to find out your own mistakes so as to correct them in time. We should develop good problem-solving habits at ordinary times. Let your energy be highly concentrated, make your brain excited, think quickly, enter the best state, and use it freely in the exam. Practice has proved that at the critical moment, your problem-solving habit is no different from your usual practice. If you are careless and careless when solving problems, it is often exposed in the big exam, so it is very important to develop good problem-solving habits at ordinary times. Third, adjust the mentality and treat the exam correctly. First of all, we should focus on basic knowledge, basic skills and basic methods, because most of the exams are basic topics. For those difficult and comprehensive topics, we should seriously think about them, try our best to sort them out, and then summarize them after finishing the questions. Adjust your mentality, let yourself calm down at any time, think in an orderly way, and overcome impetuous emotions. In particular, we should have confidence in ourselves and always encourage ourselves. No one can beat me except yourself. If you don't beat yourself, no one can beat my pride. Be prepared before the exam, practice routine questions, spread your own ideas, and avoid improving the speed of solving problems on the premise of ensuring the correct rate before the exam. For some easy basic questions, you should have a 12 grasp and get full marks; For some difficult questions, you should also try to score, learn to score hard in the exam, and make your level normal or even extraordinary. It can be seen that if you want to learn mathematics well, you must find a suitable learning method, understand the characteristics of mathematics and let yourself enter the vast world of mathematics. To learn mathematics well, senior high school students must solve two problems: one is to understand the problem; The second is the method. Some students think that learning to teach well is to cope with the senior high school entrance examination, because mathematics accounts for a large proportion; Some students think that learning mathematics well is to lay a good foundation for further study of related majors. These understandings are reasonable, but not comprehensive enough. In fact, the more important purpose of learning and teaching is to accept the influence of mathematical thought and spirit and improve their own thinking quality and scientific literacy. If so, they will benefit for life. A leader once told me that the work report drafted by his liberal arts secretary was not satisfactory, because it was flashy and lacked logic, so he had to write it himself. It can be seen that even if you are engaged in secretarial work in the future, you must have strong scientific thinking ability, and learning mathematics is the best thinking gymnastics. Some senior one students feel that they have just graduated from junior high school, and there are still three years before their next graduation. They can breathe a sigh of relief first, and it is not too late to wait until they are in senior two and senior three. They even regard it as a "successful" experience to "relax first and then tighten" in primary and junior high schools. As we all know, first of all, at present, the teaching arrangement of senior high school mathematics is to finish three years' courses in two years, and the senior three is engaged in general review, so the teaching progress is very tight; Second, the most important and difficult content of high school mathematics (such as function and algebra) is in Grade One. Once these contents are not learned well, it will be difficult for the whole high school mathematics to learn well. Therefore, we must pay close attention to it at the beginning, even if we are slightly relaxed subconsciously, it will weaken our learning perseverance and affect the learning effect. As for the emphasis on learning methods, each student can choose a suitable learning method according to his own foundation, study habits and intellectual characteristics. Here, I mainly put forward some points according to the characteristics of the textbook for your reference. L, pay attention to the understanding of mathematical concepts. The biggest difference between high school mathematics and junior high school mathematics is that there are many concepts and abstractions, and the "taste" of learning is very different from the past. The method of solving problems usually comes from the concept itself. When learning a concept, it is not enough to know its literal meaning, but also to understand its hidden deep meaning and master various equivalent expressions. For example, why the images of functions y=f(x) and y=f- 1(x) are symmetrical about the straight line y = x, but the images of y=f(x) and x=f- 1(y) are the same; Another example is why when f (x-l) = f (1-x), the image of function y=f(x) is symmetrical about y axis, while the images of y = f (x-l) and y = f (1-x) are symmetrical about the straight line x = 1. 2' Learning solid geometry requires good spatial imagination, and there are two ways to cultivate spatial imagination: one is to draw pictures frequently; Second, the self-made model is helpful for imagination. For example, the model with four right-angled triangular pyramids is much more seen and thought than the exercises. But in the end, it is necessary to reach the realm that can be imagined without relying on the model. 3. When learning analytic geometry, don't treat it as algebra, just don't draw it. The correct way is to calculate while drawing, and try to calculate in drawing. On the basis of personal study, it is also a good learning method to invite several students of the same level to discuss together, which can often solve problems more thoroughly and benefit everyone. In chemistry study, it is not difficult. Learning chemistry is about rules. Chemistry is microscopic, so we must master the essence of matter, that is to say, take more notes, think hard and remember more. As for physics, nature is the macroscopic aspect of matter, so we must pay attention to understanding the physical scene of matter, and more importantly, we must be diligent in thinking and do more problems, and we must sum up the essence and laws of matter. The adoption rate of uncertain answers: 40.0% on August 3, 20081.10: 06. We should arrange a simple and feasible plan and improve our learning methods. At the same time, we should properly participate in school activities and develop in an all-round way. In the process of learning, we must: listen more (attend lectures), remember more important question structures and concepts, ask more questions (if you don't understand), do more homework (do experiments), review more and summarize more. Concentrate by taking class notes. At other times, we must ensure the study time and the quality of each subject, and we must not be partial to the subject. You must get enough sleep (8 hours) every day to ensure learning efficiency. Arrange appropriate free time to communicate with family and friends. Through unremitting efforts, let your grades improve and stabilize step by step. Study hard for the exam, be careful when sprinting, and be calm when sprinting. After the exam, you should sum up carefully so that you can study better in the future. Now: let go of the burden and study hard at ordinary times. Before the exam: prepare carefully, during the exam: never give up, after the exam: calm down. Remember! Success always comes from unremitting efforts, and success always belongs to diligent people.

Hope to adopt
