Conceptual photography of algebraic expressions

1. Do some exercises in the single-subject senior high school entrance examination over the years. You can look at the answer and ask the teachers and classmates. The purpose of reading the answers is to learn how to answer the questions in the senior high school entrance examination and correct the bad problem-solving habits and methods in your usual study. Write down the wrong questions in red ink. If you can't write them down, correct them and stick a small note. Each copy should be corrected by yourself so that you can browse it before preparing for the exam.

2. Summarize the problem-solving methods and some common knowledge, but there is no knowledge that must be learned in the textbook. This part of knowledge should be recorded in a small notebook for easy browsing before the exam. Because you can't use it every day, you will forget it.

3. Set a set of wrong questions, and don't copy them again. If you want to keep the problem sets you have done in the senior high school entrance examination, you can order them together. It is best to use paging folders to store materials.

4. All subjects should do the simulation questions of the senior high school entrance examination according to the time of the senior high school entrance examination, don't look at the answers, finish and record the time within a limited time, and pay attention to whether the time for doing the papers is shortened or extended. Complete your own modifications and find out the shortcomings. Keep the test papers with errors and sort them. Spare ones can't be thrown away. Keep the test papers of each unified mock exam and bind them together. If you have the ability, find simulation questions in other test areas (counties), as well as pre-test simulation questions in key middle schools (schools with senior high school entrance examination teachers).

The second round: strengthening the test center of the senior high school entrance examination, the finale: (time: 15 days)

1. Find the finale of each school to do, or over the years, which is the direction of the senior high school entrance examination.

2. Questions not mentioned before may or may not come out this year when reviewing here.

3. Find the children of classmates or parents and friends to exchange the finale exercises and increase their popularity.

The third round: browsing before the exam (three days before the exam, the general school will leave school one week before the exam. )

1. Take out all the knowledge points (books) and summaries you have learned before. At this time, do what you should do, and do what you shouldn't do. That's all.

Take out all the problem sets I have done before and see if there are any mistakes, and see when I will make mistakes in solving problems. These mistakes should be avoided in the senior high school entrance examination.

3. Read the textbook knowledge from the beginning again, take a look at the key points and points you have drawn, and remember it again, which is conducive to thinking during the exam.

Math:

The main thing is to recite the formulas and definitions in the textbook. If you are proficient, you can open your mouth and come.

Do more exercises in order to master the skills and tricks learned from practice. Different problems have different methods and skills, especially the fixed point problem in function is a hot issue now. Do more, but don't do too difficult questions, focus on learning. The focus of junior high school mathematics learning is function (including linear function, proportional function, inverse proportional function and quadratic function), with emphasis on meaning and nature; Triangle (including basic properties, similarity, congruence, rotation, translation, symmetry, etc. ); The nature, definition and area of quadrilateral (including parallelogram, trapezoid, prism, rectangle, square and polygon);

Physics:

The main thing is to remember the formulas and definitions in the textbook (understanding is not rote learning) and read the experiments in the textbook. To understand completely, just fill in all the experiments in the book, which is the focus of the exam. Physics includes acoustics, optics, electricity, heat and mechanics. Only these parts.

The focus of acoustics is the principle: 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-parallel nature 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, 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.

There are many mechanics: simple machinery (including lever, pulley, shaft, slope, work, power, energy conversion, etc. ) Mainly master formulas, derived formulas, and the relationship between formulas, experimental methods and conclusions.

Chemistry:

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. Mastering the calculation of mass fraction is the key. There is only one chemical calculation in junior high school, so it is necessary to know about it. The preparation and collection of various gases are the key points, and more exercises are needed to master the questions.

Language:

Grasp the key points and skillfully use methods

Now the senior high school entrance examination has entered the sprint stage. At present, students have two kinds of mentality in reviewing Chinese: some students think that there are many Chinese knowledge points, and the senior high school entrance examination pays attention to students' extracurricular migration ability, and the textbook content is less, so they often focus on some "crash" subjects, which makes them impetuous when reviewing Chinese; There are also some students who think that the exam has no effect after carefully reviewing the textbook knowledge and doing a lot of reading questions. They felt that there was no way to start reviewing Chinese, so they simply gave up. These practices are very undesirable. In fact, Chinese, like other subjects, has its own knowledge system and review rules. Judging from the students' review in previous years, in the sprint stage, if we can follow the teacher's review plan, review and form a knowledge network, answer questions according to the correct skills and methods, and be sure before the exam, we can achieve ideal results in the exam.

So, what strategies and methods should be paid attention to in the final sprint stage?

Let's briefly talk about the practice of our school teachers in the final review stage:

First of all, we should carefully "thoroughly" the examination questions of the past two years. In the past two years, the structure, content, type and quantity of senior high school entrance examination questions have remained basically unchanged. The examination paper is divided into four sections: accumulation, classical Chinese reading, modern Chinese reading and composition. The content of the examination questions is relatively stable, and the purpose of the examination is clear: from the accumulation and application of famous sayings and sentences in and out of class, to the reading of classical Chinese in and out of class, to the reading of modern Chinese after class, and finally to the writing of topic composition. Pay attention to the examination of students' knowledge accumulation, especially the examination of students' ability to analyze and solve problems in combination with life practice and life experience. How to analyze the examination questions in recent two years? Now only four parts of the test paper are briefly explained.

First, the accumulation part. The scope of the exam is basically the famous sentences that are required to be recited in the reading questions of junior high school teaching. Reciting and reviewing should not only strengthen memory, but also understand it and use it flexibly. We should not only recite the article, but also implement every word, especially the words that are often wrong in dictation.

Always "looking back" Remember: one word difference, the whole game is lost.

Second, the classical Chinese part. The scope of classical Chinese examination in class is teaching and reading articles in junior high school. Pay attention to the key points when reviewing. According to the examination scope and requirements of the syllabus and your familiarity, you should choose the key review content. Generally examine the meaning and usage of function words and content words commonly used in classical Chinese. Content words often examine words with polysemy, different meanings in ancient and modern times and flexible parts of speech; The focus of sentence examination is the sentence structure and sentence meaning of key sentences; The examination of the content is basically the same as that of modern Chinese. From words, phrases and sentences to literary common sense, thoughts and feelings, expression techniques, etc. We should find out the main points and sum up the rules. Second, we must choose a good title. Choosing beautiful articles in teaching and reading content is often the most typical article with the widest knowledge coverage in classical Chinese, so that review can get twice the result with half the effort.

In the past two years, most of the extracurricular reading of classical Chinese in the senior high school entrance examination chose story paragraphs. The content is relatively simple, and the content of the investigation is basically the same as that in the classroom. When doing problems, we must pay attention to the connection with the texts or knowledge points learned in class, and pay attention to the migration and application from class to extracurricular.

Classical Chinese reading problems are mainly divided into two categories. One is translation. The solution to this kind of problem is:

(1) Have a general understanding of the full text and grasp the text tendency. (2) Understand the meaning of the translated sentence context in detail, translate it word by word, and make corrections, reservations, deletions, additions and adjustments. When translating, pay attention to the key words in the sentence, which are often the score points. (3) The meanings of words in the text can also be deduced from modern words and idioms. (4) In addition, we should pay attention to some special phenomena, such as flexible use of parts of speech, different meanings in ancient and modern times, words that pass through falsehood, and compound words with partial meanings. (5) If literal translation fails, use free translation. We must infer from the context, not stick to the original structure, and boldly speculate in connection with real life. The second is enlightenment. When answering such questions, we should pay attention to the ideological tendency, grasp the author's basic emotional position, contact the main plot and main characters of the article, and grasp the key sentences to think and answer from multiple angles and sides.

Third, the reading part of modern literature. It is necessary to seize the "test center" and master the answering skills. In the past two years, most of the modern Chinese reading tests in the senior high school entrance examination are a discussion-oriented essay and a natural science article. Therefore, in the final review, we should choose these two types of articles as much as possible and practice in extracurricular selection. In addition, in the setting of reading topics, it is generally examined in the order of "whole-part-whole". When doing the problem, we should firmly remember that "the answer is not in your mind, but only in the original text", which is also the only criterion for us to test the effect of solving the problem. The examination of any article focuses on two aspects, one is the screening of information, and the other is the understanding and analysis of reading materials. In reading review, we should pay attention to the relationship between sentences and paragraphs, understand the author's point of view and the writing intention of the article, and grasp the article as a whole. First of all, we should understand the two questions "What did you write" and "Why did you write". The most important and effective way is to "get off the pole by boat"-find the lines in the original text.

Seek answers. For example, the topic of overall perception often requires candidates to answer questions such as "what is the main content of the article" or "what is the author's main point of view". When doing this kind of problem, we should consider it from three aspects: looking at the topic, looking at the beginning and end, looking for comments,

Lyric sentences. These commonly used methods and ideas must be memorized. For another example, you can answer the question of "understanding the meaning and function of sentences" that students think is the most difficult to answer: first, observe the characteristics and position of sentences, and analyze their ideographic and structural functions; Combined with context, grasp the most critical words in sentence expression and point out their contextual meanings. This kind of topic mostly examines sentences that play a key role in the expression of the article, or sentences that use rhetorical devices such as metaphor and questioning, so analyzing and grasping the characteristics of sentences is the key to doing this kind of topic well. All kinds of questions have certain ideas and methods to answer, don't blindly do reading questions.

Fourth, the composition part. "Topic" composition is still the mainstream of this year's exam. In the final stage, we should read more books and newspapers, broaden our horizons, understand the information of the times, grasp the pulse of the times, learn the language style and organizational ability of others, accumulate materials for writing and replenish fresh blood. Although I am nervous about studying, I still have to "squeeze out" ten to twenty minutes to read books and newspapers every day. In writing, we should be good at focusing on the big picture, starting from the small, seeing the big from the small, and learning to "see the sunshine with a drop of water" and "say human feelings with half a petal"; Be good at association and publicize personality. Let the article reflect your sincere feelings and rich literary accumulation, so as to have both literary beauty and rich life.

Secondly, we should develop good study habits in review.

Over the years, there are some problems in the answer sheets that candidates don't read the original text carefully and can't carefully examine the questions. When doing reading exercises at ordinary times, we must form the good habit of carefully examining questions, accurately grasp key words, and then answer. In addition, attention should be paid to writing. If you scribble at ordinary times, there will be typos accumulated and you will lose points in writing. As the saying goes, "habit becomes nature", if you can't develop good reading and writing habits at ordinary times, you will lose some unnecessary marks in the exam.

In short, "many a mickle makes a mickle" is an important feature of Chinese learning. To improve Chinese performance, we need solid basic knowledge, correct thinking in answering questions, and strong understanding and expression skills. Of course, students can focus on reviewing according to their actual situation. If all three can be taken into account, I believe you will achieve excellent results in the senior high school entrance examination.

Make a plan and review diligently.

With the approach of the senior high school entrance examination, some students begin to feel nervous and flustered, and feel a little confused and helpless in the next Chinese review. Here, according to the characteristics of Chinese subject, I talk about my views on Chinese review, hoping to play a certain guiding role for students.

First, carefully interpret the "Examination Instructions" and strengthen the sense of goal. The explanation of Chinese examination every year is the direct basis for the proposition of senior high school entrance examination. In order to avoid detours and improve the efficiency of review, I think students should seriously study the items listed in the "Examination Instructions" under the guidance of teachers, make clear the objectives, compare them item by item, and implement them in practice, so that the review can be truly targeted.

Second, make an accurate review plan. "Everything is established in advance, and it will be abolished if it is not planned." Effective behavior comes from accurate planning. Under the review plan made by the teacher, students should have their own personal plan, including the arrangement of time and content, as well as review methods and consolidation means.

Third, pay attention to special review.

The first round of review is from early February to early April, focusing on textbooks, deducting books according to the outline, and laying a solid foundation in words, words, sentences and articles. After the first round of review, I think the second round

Review (early April-around May 20th) should enter the special review stage, that is, according to the test instructions and the rules of the senior high school entrance examination, break the original subject order, sort out and strengthen training. In the general review of Chinese, I think the special review is the most important stage. Through the review at this stage, we can systematize the basic knowledge scattered in the text before, let students stand on a higher platform and overlook the Chinese knowledge system, and eliminate the confusion that trees can't see the forest. So we should all pay attention to the review at this stage. According to the exam items listed in the Chinese exam descriptions over the years, we can divide the review content into four topics: First, basic knowledge. Including 1 pronunciation, 2 Chinese characters, 3-word phrases and sentences, 4 punctuation marks, 5 rhetorical methods, 6 styles and literary knowledge. The second is to read classical Chinese. Third, modern reading includes narrative, argumentative, expository, novel and prose. The fourth is writing. When reviewing topics, we should first make clear the review points of each topic, and then consolidate them with exercises. In the review process, in order to better remember and master some knowledge, we can also take the form of list and reclassification. For example, when reviewing literary knowledge, memories can be classified according to the author's name, age (nationality), evaluation of the author, title, genre, source list and so on. When reviewing classical Chinese, we can classify and master it according to the list of common words, flexible use of parts of speech, sentence patterns of classical Chinese, the meaning and usage of commonly used function words in classical Chinese, and the meaning of ancient and modern words. According to some open questions about the accumulation of ancient poetry in the senior high school entrance examination in recent years, we can also try to sort out ancient poetry, for example, it can be divided into lofty aspirations, war scenes, patriotism and love for the people, nostalgia for family, pastoral scenery, frontier scenery, spring, summer, autumn and winter, romantic love, encouraging learning to cherish time, optimism and confidence, full of philosophy, nostalgia for history, adversity and so on.

Four, simulation exercises (or comprehensive training)

May 21-early June can be called the third round of review. This round of review is mainly based on simulation training, which can help students to test the effectiveness of their study after completing the special review, and at the same time, it can play a role in practicing for the senior high school entrance examination and improving their ability to take the exam. When training, you can choose the test questions of the senior high school entrance examination in the past three years or choose the questions whose difficulty and capacity are similar to those of the senior high school entrance examination in recent years, which really plays the role of simulation.

Problems needing attention in verb (abbreviation of verb)

1, review is to sort out what you have learned, such as words and sentences, rhetoric, reading and writing. But the purpose of reviewing knowledge is not to remember, but to apply. Take reviewing rhetoric as an example: it is not whether you know what metaphor is and what personification or parallelism is, but whether you understand why others use these rhetorical methods in their articles and whether you can use them yourself.

2. Review is to review the methods taught by teachers, such as understanding words and sentences, reading classical Chinese and modern Chinese, and writing. But reviewing various methods is not to remember, but to see if they can be used.

3. Review can't just look at what you have learned, but should bring the old with the new, and cultivate and improve the ability to use the original knowledge to solve problems. Take the review of classical Chinese as an example: of course, you should review the text, but you should also find some extracurricular short articles that are quite difficult to read, see how your reading ability of classical Chinese is, and move from one class to another. The review of modern literature should be more like this.

English

You need to review the English words in grade 1-3, summarize the phrases and grammar of each unit, and memorize the key texts. Find a grammar book to read the grammar learned in junior high school, practice listening and do exercises.

History, geography and politics are all the same, and the short-term effect is very obvious, which can be obviously improved in a few days. First, review methods

Three rounds of review. The first round of review is the review of units and chapters of basic knowledge. Through the first round of review, students can systematically master basic knowledge, basic skills and methods, and form a clear knowledge network and a stable knowledge framework. We start with the double basics, closely follow the knowledge points of the senior high school entrance examination and organize the units to pass the customs. Combined with the actual situation of students, strict unit clearance is carried out, and the basic knowledge is consolidated for some C and B students through diligent investigation, multiple questions and multiple repetitions. On the basis of mastering knowledge flexibly, we also pay attention to cultivating students' reading comprehension, problem analysis and problem solving ability.

The second round of review breaks the boundaries of chapters and implements large unit, small comprehensive and special review. The second round of review is by no means the compression of the first round of review, but the process of synthesizing, consolidating, perfecting and improving the knowledge points. The main task and goal of review is to complete the sorting, induction and integration of all parts of knowledge, make all parts of knowledge an organic whole, and strive to realize the focus of basic knowledge, the networking of key knowledge, the questioning of network knowledge and the life-oriented problem design. This round of review should take mathematical thinking methods as the main line and students' comprehensive training as the main body, reduce repetition and highlight key points. In the application of mathematics, we should pay attention to the integration of mathematics knowledge with life and other disciplines, interspersed with special review (such as chart information questions, economic decision-making questions, open questions, project design questions, exploratory questions, etc. ), thus infiltrating students' awareness of life-oriented problems, thus improving their understanding ability of reading comprehension questions.

The third round of review is the stage of deepening and consolidating knowledge and ability. Review the organization of materials in order to give priority to the test questions and simulation questions in the senior high school entrance examination, give kickbacks to the teaching materials, make up for missing items and strengthen training. At the same time, we should teach students some necessary skills and methods to take the exam, so that students have enough confidence to face the senior high school entrance examination calmly. Due to the nervous study before the exam, some students are easy to be anxious and impetuous, which leads to the decline of learning efficiency. At this stage, we should also pay attention to adjusting students' mentality in time so that they can take the senior high school entrance examination with the best mentality.

The Golden Plan of Mathematics Review for Senior High School Entrance Examination

Lay a good foundation and improve your ability. Review time is tight and the task is heavy. In a short time,

How to improve the efficiency and quality of review is a concern of every junior three student. To this end, let me talk about.

Some of my own ideas are for your reference.

First, lay a solid foundation.

1. Pay attention to textbooks and review them systematically. Junior high school mathematics foundation includes basic knowledge and basic skills. At present, the proposition of the senior high school entrance examination is still based on basic knowledge questions. Some basic questions are original or modified in the textbook, and the big question behind is "higher than the textbook", but the prototype is generally an example exercise in the textbook, which is an extension, deformation or combination of the topics in the textbook. Textbooks should be the main content of review.

For example, in 2004, the senior high school entrance examination in Liaoning Province 17: AB is the chord of the circle O, and P is on the chord AB of the circle O.

A little, AB 10cm, AP 4cm, OP 5cm, then the radius of the circle o is () cm.

This question is the original title of the third grade geometry textbook. There are many such problems, which tell us the importance of learning textbooks well. When reviewing, we must dig deep into the textbook, summarize and sort out the contents in the book, and form our own knowledge structure, especially after reading and thinking, some middle school entrance examination questions will be extended and expanded on this basis. It is ineffective to blindly engage in sea tactics and do a lot of exercises all day, so we should pay attention to the induction and arrangement of problem-solving methods to make inferences.

2. Lay a good foundation and learn to think. Nearly 70% of the senior high school entrance examination is divided into basic questions, and if you count the basic points in intermediate questions and more difficult questions, the proportion will be even greater. Therefore, the application of basic knowledge should be skilled, correct and fast. We should not only listen to the teacher in class, but also dare to question and actively think about methods and strategies. You should "know" and "learn" yourself through the teacher's teaching, especially in the process of solving new situation problems, and realize how to think correctly.

3. Pay attention to the understanding of basic knowledge and the study of methods. Basic knowledge is not only the concepts, formulas, axioms and theorems involved in junior high school. To master the relationship between basic knowledge, it is necessary to clarify the knowledge structure, form the whole knowledge and use it comprehensively. For example, the moving point problem involved in the senior high school entrance examination is not only a combination of equations, inequalities and function problems, but also often involves similar triangles and proportional derivative in geometry. In addition to the basic knowledge, the mathematical proposition of the senior high school entrance examination also attaches great importance to the examination of mathematical methods. Such as collocation method, substitution method and discriminant method.

Second, comprehensively use knowledge to improve their own ability.

1, improve the ability to solve problems by using mathematical knowledge comprehensively. Students are required to relate the knowledge in each chapter and use it comprehensively to avoid analogy. At present, we should review according to our own reality, check for leaks and fill gaps, and do a good job in knowledge induction and problem-solving methods induction. Throughout the examination of ability in senior high school entrance examination, it can be roughly divided into two stages: one is to examine the ability of operation, spatial imagination, logical thinking and solving pure mathematical problems; The second is to emphasize reading ability, innovative exploration ability and mathematical application ability. When doing problems at ordinary times, you should do the following:

1) Deeply understand the essence of knowledge, and strengthen the exercise of your ability to examine questions at ordinary times, so that you can be unhurried and handy after changing the expression form of the proposition. 2) Seek different methods to solve problems and flexible ways of thinking. Paying attention to the broadness of one's own thinking, finding different methods for the same problem and realizing multiple solutions to one problem are conducive to breaking the mindset, opening up ideas and optimizing problem-solving methods. 3) After changing the position, shape and size of geometric figures, we can find the relationship between the figures and know which quantities have not changed and which ones have changed. For example, the matching degree of graphics before and after folding is the key to solve the problem.

2. Pay close attention to key contents and practice hot issues appropriately. For many years, the "equation", "function" and "line type" of junior high school mathematics have been the key contents of the senior high school entrance examination. "Equation Thought" and "Function Thought" run through the examination paper. In addition, "open questions", "exploration questions", "reading comprehension questions", "scheme design" and "hands-on operation" are also hot topics in the senior high school entrance examination in recent years. Most of these questions come from textbooks, and some have different knowledge requirements, but the questions are novel, the background is complex, and the text is long, which is difficult to sort out. Therefore, we should pay attention to the study and training in this field in order to be familiar with and adapt to these problems. How to Review Mathematics for Senior High School Entrance Examination

First of all, as candidates, we must understand the relevant policies of the senior high school entrance examination and avoid detours and going the wrong way. Candidates should carefully study the Instructions for the Senior High School Entrance Examination, understand and see clearly the scope of the examination, focus on the grading standards in the reference answers of sample questions, remember every grading point, and avoid "skipping" when solving problems.

Second, know yourself and build self-confidence. After all, the senior high school entrance examination is not a college entrance examination. Its main function is to understand the mathematics learning process of students in compulsory education and evaluate their basic level of mathematics. Secondly, it is the main basis for high school enrollment. Looking at the senior high school entrance examination questions all over the country in recent years, the difficulty distribution of the test papers is mostly controlled at 4: 5: 1 or 5: 4: 1. Therefore, candidates don't have to doubt their math ability and level because they can't solve some math problems. It can even be said that as long as they work hard in the review stage of this semester, they will not make mistakes in the senior high school entrance examination.

Third, make a review plan and arrange the review time reasonably. Generally speaking, three rounds of review can be arranged for the senior high school entrance examination review. The first round, find out the context of junior high school mathematics content and review the basic knowledge system. According to the knowledge system of junior high school mathematics, the content of Chapter 21 can be summarized into eight units: ① number and formula {real number, algebraic formula, fraction, quadratic root} ② equation (group) and inequality (group) {linear equation (group), linear inequality (group) and quadratic equation. About 60% of the questions in the senior high school entrance examination belong to the "double base" that students usually study. In order to ensure the score of this sub-topic, we must systematically review the teaching materials and make clear what we must master. Here, I suggest that all candidates must first cooperate with your teacher to review, don't take a cursory look, aim too high, and don't make another set; Secondly, review should be accompanied by appropriate exercises, and the difficulty of exercises should be controlled, mainly in middle and low grades. In addition, we should develop the good habit of marking questions that we find difficult or easy to make mistakes, so that we can review them in the second stage. Note: it is not easy to train the questions too early, and the reference materials should be in units. At this stage, the review should be detailed, not cursory.

In the second round, focus on the hot spots, grasp the weaknesses, and review the difficult knowledge specially. The purpose of learning mathematics is to use mathematics. In recent years, a large number of active, interesting and enlightening questions have emerged in the senior high school entrance examinations in various places. Candidates should carefully review these hot issues and make special breakthroughs under the guidance of teachers. Hot topics generally include: reading comprehension, open inquiry, practical application, geometric algebra synthesis, research-based learning and so on. Note: You should have a compilation of the senior high school entrance examination questions in various provinces and cities. We should know that the wonderful questions appearing in foreign examination questions are often the reference of local propositions.

In the third round, lock the target, prepare for the senior high school entrance examination and conduct simulation training. After the first and second rounds of review, the basic knowledge of learning has basically passed, and the third round of simulation training should be in the middle and late May. Its purpose is to check and fill the gaps, adjust the examination psychology, and enter the examination room in the best state. Candidates are advised to use test papers from all over the country, set standard time and conduct self-simulation tests in addition to normal simulation training in schools. Note: Self-grading should be based on grading standards, and you can't just look at the answers without looking at the scores.

The general review of junior high school mathematics has gone through three rounds. In the first round of review, the following questions often appear:

1. Review is unplanned and inefficient, which is reflected in inaccurate key points, inappropriate details, low difficulty, and inaccurate grasp of the upper and lower limits of the outline and teaching materials.

2. The review is not solid, and there are many loopholes, which are reflected in the high score of 1), which is too difficult and loses a lot of basic knowledge. 2) The review speed is too fast, and there are countless problems in students' minds. It's too late to rework. There are many loopholes if you don't rework. 3) the requirements are too loose, the requirements for students are not implemented, and a large number of review materials are only sorted out and not corrected; No homework.

3. There are many questions, and the ability is not high, which is manifested in: 1) taking the title as the topic instead of the title method, being satisfied with the answers after solving the problem and ignoring the summary of the law of solving the problem. 2) The topics are out of order, not step by step. 3) Too many repetitive topics, resulting in a waste of time and energy.

In the second round of review, the following problems should be prevented:

1. Prevent the mechanical repetition of the first round of review.

2. To prevent simple questions, we should use the topic theory method.

3. Prevent too many problems

In the third round of review, the following problems should be prevented:

1. Do more exercises, practice instead of speaking.

2. Use review materials instead of coaches, do not prepare lessons, and the classroom organization is loose.

3. Only pay attention to knowledge counseling, not psychological training.

Suggestion:

Let the students learn from their mistakes, make some comments and set up their own error files. For valuable questions, ask students to sum up what knowledge points are examined in the question, from which angle each knowledge point is examined, what mathematical thinking methods are examined in the question, what are the solutions to this problem, and what is the best solution? When I make a mistake, is it a mistake in knowledge or method, a mistake in solving problems or a mistake caused by psychological defects? Effectively solve the problems of seeing but not right, being right but not complete, being whole but not beautiful.

1. You must listen carefully in physics class, or spending twice as much effort after class will not have such a good effect.

2. Do more exercise. If you don't understand, be sure to ask at once. If you can't ask, write down the pages in your notebook. There are many problems to contact, and the exam is just a piece of cake.

When you don't have time to review, read the wrong questions and make sure you understand what you don't understand.

If the teacher in this class is not very good at explaining the topic, ask the better teacher in the next class while the teacher is away.

5. Be sure to keep a calm mind and master the time during the exam.

This is written by a teacher. You can try. . But I'm not sure if you can get into the school you want.

But let's cheer together. That old saying is well said. No pains, no gains. . Is it?

In addition, our teacher also asked us to buy some materials with detailed answers, such as 38 sets of Tian Li, and 3-year simulation of the five-year senior high school entrance examination (5.3 for short). I am exhausted.
