Efficient sprint-physics
Automatic physics
For many students, physics is a difficult subject, so we must master the methods. It is best to have a pyramid structure of "basic knowledge-knowledge network-brushing questions", and we must lay a solid foundation.
Basic knowledge is very important.
No matter how difficult the topic is, it is nothing more than a synthesis or variation of the basic things. In the limited review time, we should make a wise choice, that is, grasp the foundation. All kinds of formulas, theorems and experiments should be 100% mastered.
Especially in electricity and mechanics, there are many theorems and formulas, which need to be sorted out and memorized! For students with good grades in physics in grade three, some fragmentary knowledge points can be consolidated and reviewed according to the teaching materials.
For students with weak foundation, it is best to take out the notes of grade three and review them again, so as to achieve the effect of leaving no loopholes.
2. Find the key points and make efforts to break through.
Acoustics focuses on principles: timbre, tone and loudness.
The focus of optics is the nature of light: reflection, refraction, plane mirror principle, lens imaging (emphasis) and application.
Electricity is mainly the series and parallel properties of current, voltage and resistance, electric power, electric work, Joule's law, electromagnetic properties, phenomena, experiments, unit conversion (there will be many problems here, which is the key point), formulas should be familiar with, and deformation formulas should be used quickly.
Thermology is mainly the change of material state and the application of thermodynamic formula; Give you a formula that is not in the book but was tested in the exam: Q=mq, which is the calculation formula of solid heat. Q is heat, m is mass, and q is calorific value.
In addition, there are simple machines (including levers, pulleys, shafts, inclined planes, work, power, energy conversion, etc.). ) mainly master formulas, derived formulas, the relationship between formulas, experimental methods and conclusions.
These key contents are all knowledge points that the senior high school entrance examination likes to examine over the years, so we must focus on breakthroughs.
3. Find the special breakthrough of the loophole
By combing methods, refining skills and brushing a lot of real questions, I have a particularly clear understanding of the examination forms, high-frequency test sites and common mistakes in my own examination area. At the same time, I have to find my own weaknesses and where are the points that are often deducted? Find the leak and plug it.
Efficient sprint-chemistry
1, return to the textbook
Review can be divided into chapters, such as getting familiar with the periodic table of chemical elements, understanding the requirements of chemical instruments, or dividing the same family of elements into blocks, and simply understanding the basic knowledge such as element properties and equations.
2. Keep in mind the classification of basic knowledge
You need to master the name of element 1-20 and the writing of element symbols. It is necessary to write chemical formulas and equations correctly and memorize the common names, colors and smells of various drugs. To be proficient in the calculation of quality scores, this is the key. There is only one chemical calculation in junior high school, and you must know it. The preparation and collection of various gases are the key points, and more exercises are needed to master the questions.
3. Skillfully use the formula by doing the problem.
Chemical knowledge is scattered and abstract, but there are rules to follow and it is not difficult to master. Choose some guide books with problem-solving ideas, do some exercises according to your own learning situation, and understand the application of the formula in solving problems; By doing some exercises and exercises, we can find the problems in our study, and concentrate the problems in a notebook, which can make the follow-up review more targeted.
Efficient Sprint —— Morality and Rule of Law
1, basic knowledge understanding
Morality and rule of law are the only subjects that must be correct in multiple-choice questions, because multiple-choice questions are generally simple, and a basic understanding of knowledge is enough.
2. Build a knowledge framework
Form a knowledge network on the basis of basic knowledge. If you encounter related problems in the exam, you can call out the knowledge network to see if it is related to the materials and leave relevant ones. This can minimize the possibility of losing points. Of course, in addition, some appropriate summaries are also necessary.
3. Form the thinking of answering questions with the help of the teacher.
In addition to memorizing knowledge, Taoism attaches great importance to answering questions.
The teacher's answering skills and problem-solving ideas are very rich. In the process of explaining the test paper, we must pay attention to the teacher's thinking and summarize some answering skills. These will be of great help to our exams.
Efficient sprint-history
1, take more notes
History should be good at grasping the relationship between historical context and historical events from a macro perspective. Notes are particularly important to history, because the classification of people's education edition is actually unreasonable, not according to historical years, but according to political, economic and cultural classification, and Chinese and foreign history intersect. This completely separates the normal development of history, and many cross-book connections will be difficult to find.
Remember all the historical facts by taking notes, that is, read all the small notes. As for the influence of background meaning, it is basically summarized by the teacher. I have to look through the books to see if there is anything the teacher didn't mention, and try to remember it all.
2. Grasp the connection between historical events.
Historical notes should also grasp the connection between major historical events. For example, the world history from the Renaissance religious reform after the Middle Ages to the bourgeois revolution in Britain and France is at the same time as the geographical discovery of bourgeois development and even the latest industrial revolution.
Only by putting all this together can we really understand what happened during that time. At least close your notes, talk about the Opium War, and tell all about China's background, international background, process results and significance. Only in this way can we ensure that we don't lose points when doing history questions.
Therefore, history is a big project, and taking it slowly requires care and patience.
