Zhengzhou, Henan: How to prepare effectively and quickly for the 2021 high school entrance examination? Teachers from No. 8 Middle School offer advice to students

Su Xiaoqin, a Chinese teacher at Zhengzhou No. 8 Middle School, Henan Province, a key teacher in Henan Province, a key teacher in primary and secondary schools in Zhengzhou City, the fifth session of Zhengzhou City, and the host of Zhengzhou City Chinese Studio.

1. Lay a solid foundation

As the saying goes: A tall building rises from the ground. No matter how high or far your dream is, it must start from your feet. The road under your feet is paved with solid basic knowledge. Without a foundation, everything is just empty talk and dreams. If the foundation is not strong, everything will be unstable. Therefore, to lay a solid foundation, you must do homework every day until before the exam. There are three points to note:

(1) The basics must be comprehensive and impartial. Don't be biased or give up with the mentality of guessing questions. All basic knowledge involved in textbooks and course standards must be treated equally, especially literary and cultural common sense and simple grammar knowledge must be reviewed.

(2) Be sure to pay attention to the textbook. All kinds of review materials such as the Sunflower Book cannot replace textbooks. Textbooks are an inexhaustible treasure. Here, we are particularly reminded to pay attention to the after-class exercises.

(3) Accumulate more composition materials. I can recite three hundred Tang poems by heart, but I can still recite them if I can't recite them. So accumulate a lot, and be able to recite some excellent arguments and beautiful words when necessary.

2. Refine and think more

There are roads in the mountain of books and diligence as the path, and the endless sea of ????questions is the boat of thought. Last step, do you want to brush up on the questions? want! Do you want to go crazy and answer questions? don't want! There are risks in answering the questions, so be careful when answering the questions!

(1) Time is tight and tasks are heavy. Wasting time is tantamount to chronic suicide, so be sure to choose high-quality test questions. The characteristics of high-quality test questions are as follows: keep up with the times, keep up with the curriculum standards, and keep up with the reforms.

(2) You will get it every time you practice. It will take a lot of time to do a set of Chinese language test questions. How can we get a return on the time spent? The answer is that you must correct what you have done and think about what you have done. Only by constantly summarizing and reflecting can you make progress!

(3) Be obedient and do as you are told.

In this critical period, when it comes to professionalism, it must be teachers. To do professional things, you need to find professional people. For the high school entrance examination, the teachers are professional! Obeying and doing as you are told is the wisest choice you can make at this critical moment.

Dear children taking the high school entrance examination, come on!

English

Erdun Chaolu, an English teacher at Zhengzhou No. 8 Middle School, a member of the Henan Province Basic Education Subject Professional Talent Pool, a member of the Henan Province Education and Evaluation English Subject Group, and a member of the Henan Province Education and Evaluation English Subject Group. Henan Province's "Analysis and Detection" listening recorder was recruited, and he was a member of the expert team for the follow-up training of the junior high school People's Education Edition textbooks. The English review course for the Chinese National Recruitment School recorded during the 2020 epidemic was published on platforms such as "Study in Zhengzhou" and "Study Powerful Country" Well received.

The English examination for the National High School Entrance Examination focuses on testing the core competencies and discourse awareness of the English subject. In the process of review and preparation, improving the efficiency of review and preparation is the key to review. Theefficiencyandtheeffectivenessmattersmost.

First of all, make it clear that English is a language.

1. Pay attention to the flexible use of language knowledge

Basic language knowledge cannot exist independently of the text. Its effective combination with the context means flexible use. "Analysis and Testing" has a detailed and accurate interpretation of the content, question types, examination focus and requirements of the high school entrance examination. Before taking the exam, you need to carefully study the vocabulary listed in the course standards, focus on summarizing the words that you are not familiar with, as well as the new meanings of familiar words and polysemy of these words, and organize your own wordlist.

2. Check for gaps and fill in the gaps, and establish a complete knowledge system

Systematize the language knowledge that is usually scattered and study, pay attention to the connection between language points, focus on summary and strengthen application.

The review of language knowledge ultimately depends on whether you can use this language knowledge to express your own thoughts and activities, thereby establishing a complete knowledge system. For example, during the review process, listening comprehension and conversation completion can be combined. The long and short dialogues in listening comprehension are good supplementary materials to complete the conversation topics. Candidates need to adjust the "biological clock" of English learning before the test and listen to the listening speed at the recommended speed in advance to quickly enter the English state. Before the exam, you should review the long and short dialogues that you have passed in the listening comprehension test again, especially high-frequency topics. At the same time, you should also pay attention to the other expression transformations of the same sentence that appear in the dialogues, and compare them with the standard answers, and constantly Standardize your answers.

The quality of checking and filling in gaps is related to whether the basic knowledge is complete. If the knowledge system is complete, you can handle the exam with ease and remain unchanged in response to changes.

3. Pay attention to the full input of language information and focus on cultivating a sense of language

During the reading process, work hard to figure out the sentence structure and chapter structure of the language as well as the application environment of language knowledge. Pay attention to the language itself and accumulate it from time to time, and constantly think about why the language is presented in this or that way. Therefore, it is necessary to read these articles intensively before the exam, pay attention to the chapter structure and common test methods for successful reading, and analyze the article structure and main idea, which will help improve the error-prone questions such as reasoning judgment, main idea, etc. in reading comprehension. .

IV. Increase the cultivation of language skills in subjective test questions

Use the limited time to recite some short passages with decent language and authentic expressions and learn to imitate them.

●The same meaning depends on how the author expresses it, and then you can use these expressions in written expression training, so that other people's language becomes your own.

●In addition, you also need to learn different expression methods of the same meaning on the basis of solid common sentence patterns, so that your language can be varied and the readability and flexibility of your language can be enhanced.

●Language learning is: imitation and application.

Before preparing for the exam, you should sort out your "corpus" again, extract and sort out what you can and want to write from the three major themes of people and nature, people and society, and people and self, and pay attention to everything. Write sentences and paragraphs logically.

Mathematics

Shasha, leader of the mathematics preparation team for grade 9 in Zhengzhou No. 8 Middle School, has taught for 20 years, is a key teacher in Zhengzhou City, an outstanding Communist Party member in Zhengzhou City, and an educator in Zhengzhou City Excellent teacher of the bureau and civilized teacher of Zhengzhou City. He has won the first prize for quality courses in Henan Province twice, the first prize for municipal quality courses four times, and 6 articles have been published or won the first prize for provincial outstanding papers.

In the blink of an eye, it is June. For everyone who is going to take the high school entrance examination, it is obviously persistent and busy. In this final and intense sprint stage, how can we review mathematics stably?

First of all, please understand that the guarantee of high scores in the high school entrance examination lies in the basics. The secret to success in the mathematics examination is not to get all the difficult questions in each test correct, but to do all the basic questions and intermediate questions flawlessly. In a 120-point high school entrance examination mathematics paper, questions that apply basic knowledge and basic problem-solving methods account for 70-80% of the total, which is a very high proportion. Even the so-called difficult problems are mostly based on basic knowledge, and the renovation, synthesis and application of knowledge points are carried out. Therefore, everyone needs to have an accurate and systematic understanding of basic knowledge such as concepts, properties, and theorems. Master basic skills and basic mathematical thinking methods, pay attention to the connections between knowledge points, base yourself on textbooks, and lay a solid foundation so that you can naturally "take out" the knowledge you need from your brain when facing problems.

Secondly, strengthen training on problem-solving speed and accuracy. Do some objective questions and intermediate questions regularly and quantitatively to train speed and accuracy, summarize and memorize in time, and improve internalization. Do some comprehensive questions appropriately to improve your problem-solving thinking ability. When facing difficult problems, we must have the courage to find breakthroughs, reflect in time after solving problems, sum up experience, and enhance confidence.

When reflecting, you can consider the following questions:

1. Did you notice the keywords when reviewing the question? What knowledge points can be associated with the keywords? Are there any implicit conditions (common sides, common angles, midpoints) that are ignored in geometric figures?

2. Is some mathematical model used (equations, inequalities, functions or similar models, basic graphic structures)?

3. What basic knowledge and methods are involved in this question? What knowledge points are still lacking, and how can they be made up for?

4. How to accurately write the process of solving the problem? What places are easy to miss? What other problems can this solution be applied to?

Nowadays, the high school entrance examination pays more and more attention to the standardization and completeness of the problem-solving process, and try to avoid the mistakes of "knowing but not right" and "right but not completely". In the final comprehensive review, you should pay attention to the writing requirements, especially after completing the previous high school entrance examination questions, you should check your actual score according to the reference answers and scoring standards, and consult the teacher if necessary, so that you can address your usual problems and weaknesses. carry out effective training.

Thirdly, pay attention to the training of examination skills and the accumulation of examination experience. Changes in mentality during the high school entrance examination, the impact of psychological quality, the arrangement of the order of answering questions, the arrangement of exam time, and strategies for encountering difficult problems are all factors that cannot be ignored.

Some suggestions for different question types in high school entrance examination mathematics:

1. While multiple-choice questions focus on general problem-solving methods, you can also try elimination methods and special values ??according to the questions. method to improve problem-solving efficiency.

2. The basic skills for filling in the blanks are accuracy, speed and neatness. The answers should be clear and concise to avoid "timeout" and affecting the answers to subsequent big questions. Commonly used methods include direct method, specialization method, number-shape combination method, overall substitution method, etc.

3. Answer the questions as accurately as possible (the key steps, strive to be precise, rather slow than fast), and strive for success the first time. All these types of questions are scored step-by-step. When answering the questions, you should pay attention to the steps and answer patiently. During the problem-solving process, you must review the questions carefully and answer as required. If you encounter difficult questions or new questions during the exam, stay calm. If you don't know how to do it, you can put it aside temporarily. When doing so, review the questions carefully, extract key words and convert them into mathematical symbolic language. Associate relevant knowledge and thinking methods, such as equation thinking, function thinking, overall thinking, transformation of graphics (rotation, translation, axial symmetry), construction of right triangles, cut and complement of graphics, addition of auxiliary lines, etc. Don't give up easily. The big questions in the lottery have obvious levels. You can solve as many problems as you can. In this way, although you cannot reach the final conclusion, you can still get a certain score.

Physics

Yu Jingcan, leader of the physics teaching and research team of Zhengzhou No. 8 Middle School, first prize winner of the National Physics Innovation Competition, Henan Province teaching model, academic technology leader of Zhengzhou Municipal Education Bureau, Key teachers in Zhengzhou City.

With the entrance exam approaching, students have entered the sprint stage. How can we make good use of the twenty days before the exam to improve our physics scores more efficiently? The following suggestions are now put forward:

1. Start with basic knowledge to check for omissions and fill in the gaps

The physics proposition requirements for the Henan Entrance Examination are easy, moderately easy, moderately difficult, and difficult. The ratio is 4:3:2:1, with easy questions and intermediate questions accounting for 90%, so it is particularly important to check and fill in the gaps in basic knowledge before the exam. Students can sort it out from the following perspectives based on the second test situation:

1. Compare the "Scientific Content" section in "Analysis and Detection" to sort out the basic knowledge points and strengthen practice on weak points.

2. Screen the easily overlooked parts of the textbook, such as small information, after-class reading materials, after-class questions and illustrations, to ensure that the loopholes in the first round of review are filled.

3. Take another look at the recently compiled incorrect question papers, read more about the revised problem-solving process, and strengthen the correct problem-solving ideas.

2. Pay attention to the training of test-taking details and question-answering skills

Every year in the entrance examination, many students lose points needlessly due to lack of test skills. Therefore, when preparing for the exam, you should pay more attention to the details of the exam.

1． You should practice several sets of real questions before the exam, and limit the time during practice. This will not only help link individual knowledge points into a knowledge network, but also train your concentration when reviewing questions.

2. Most of the physics test questions in the entrance examination are closely related to production and life. Before the exam, you should pay more attention to hot issues, such as Tianwen-1, China Space Station, Beidou navigation, deep-sea exploration, 5G technology, unmanned driving and other physical knowledge.

3． In the high school entrance examination, there are many cases where points are deducted due to writing errors. Therefore, you must write in a standardized way during pre-exam training. Pay special attention to some physics terms that are easy to write wrong, such as "melting", "convergence", "uniform velocity", etc.

4． Summarize some practical question-answering techniques, such as "assignment method", "limit method", "analogy association method", etc. These methods are often used when answering multiple-choice questions and can improve the efficiency of answering questions during the exam.

5． Pay attention to the reasonable allocation of time for answering questions. Generally, twenty minutes should be set aside for the last two comprehensive application questions. If there is less time left, the mind may be blank and the train of thought may be interrupted due to tension, and the performance may not be as good as it should be.

3. Adjust your mentality and strive for high-level performance

After many rounds of review before the exam, everyone’s proficiency in mastering the knowledge points is not very different, but they can Whether you can take advantage of the knowledge you have mastered and apply it freely depends to a large extent on your mentality when taking the exam.

1． Before the exam, you must insist on doing a few questions every day, and don't let yourself get sloppy. However, the number of questions cannot be too large, and the difficulty cannot be too high, otherwise it will destroy your confidence.

2. You should maintain communication with teachers and parents before the exam. The purpose of communicating with teachers at this time is not to gain more knowledge. The key is to enhance confidence and reduce stress, so that you can feel more confident when you enter the exam room.

3． When answering questions, do not rely on habitual thinking when answering questions that are easy or familiar. The probability of the original question appearing in the high school entrance examination physics test questions is very low, so pay attention to the subtle changes in the questions; do not fight when you encounter difficult problems, you can bypass them first and pass them first. Doing simple questions will enhance your confidence. The more confident you are, the more active your thinking will be, which will gradually improve your examination status.

I hope that students can adjust their learning and mental state during the sprint period, work and rest reasonably, exercise appropriately, and achieve ideal results in the exam!

Morality and Rule of Law

Wei Xinxin, leader of the Morality and Rule of Law teaching and research group of Zhengzhou No. 8 Middle School, has won the first prize of Zhengzhou City’s quality course and the second prize of Henan Province’s quality course for many times. He was rated as a teaching technology model in Henan Province and an outstanding Communist Party member in Zhengzhou City.

Dear students, hello everyone, the time for the high school entrance examination is getting closer and closer. I believe everyone is making full efforts to prepare for the final sprint. Here, Teacher Wei will give you some preparation suggestions. I hope you can Give you some help

1. Based on the "Interpretation", clarify the direction of the examination.

"Analysis and Testing" provides a detailed and precise explanation of the content and examination format of the high school entrance examination, and is equipped with guidance such as classic examples, special exercises and simulation test questions. Before the exam, students need to carefully study the introduction to problem-solving methods in "Explanation and Examination", grasp the spirit of setting the questions, find the focus of sprint review, and further clarify the direction and goals of the exam.

2. Return to textbooks and solidify your knowledge base.

At the juncture of the sprint, instead of being superstitious about answering questions and crazily answering questions, it is better to use our limited energy to summarize and integrate knowledge and consolidate the foundation again, so as to achieve the effect of checking for omissions and filling in the gaps and making small improvements. Combined with the characteristics of the 2019 and 2020 high school entrance examination questions, more testing of our ability to use the knowledge we have learned to analyze and solve problems requires us to have a deeper and broader understanding of basic knowledge. Therefore, it is necessary to deeply understand and master some core concepts and main knowledge, to know what is and why, to form a certain level of thinking, to build a knowledge grid, and to systematically and comprehensively master the knowledge base.

3. Avoid question-filled tactics and train well.

Since the number of multiple-choice questions in the 2021 high school entrance examination has increased to 17, with a maximum score of 34, which accounts for almost half of the entire paper, it is very important to strive for full marks in the multiple-choice questions, which is very important for getting high scores in the high school entrance examination. .

We can use our spare time to conduct special training on multiple-choice questions. Each set of multiple-choice questions should not exceed 15 minutes. If the entire set of papers is no more than 55 minutes, we can train the speed and rhythm of answering questions, standardize the language of answering questions, and find the sense of questions to adapt to the requirements of the exam.

4. Sort out the reference materials and prepare to open the book.

Morality and the Rule of Law are open-book exams, but the exam time is limited. You must not bring a bunch of books to the exam room to read them, especially the so-called "Quick Check" materials. If you already have similar information in hand, it is recommended that you treat it as a test question set, read it, think about it, and select the rough and the essential, eliminate the false and retain the true, and do not blindly trust it. At this stage, you can sort out the papers you usually make and organize them into volumes. The textbook, "Analysis and Detection", is a book that I use most when reviewing and preparing for exams. You can just bring the compiled materials with you.

5. Based on the characteristics of the subject, pay attention to hot current affairs

Topicity is a typical feature of examination papers in the ethics and rule of law disciplines. Almost every question is presented with hot current affairs as the background material. , and 2021 is another year with constant major events and frequent hot spots. We need to analyze the possibility of examination propositions in a targeted and multi-angle manner for these hot spots, such as the Fifth Plenary Session of the 19th CPC Central Committee, the Poverty Alleviation Summary and Commendation Conference, The party's centenary birthday, legal revisions, innovative development of traditional Chinese medicine culture, etc. all require us to prepare for the exam from multiple angles and in an all-round way according to certain ideas.

6. Take the exam calmly, be brave and careful and you will win

(1) Review the questions carefully and clarify the intention of setting the questions. You can circle key words on the test question paper to grasp the main purpose of the material, clarify the direction of answering the questions, and grasp the key words; in addition, you must avoid inertial thinking, do not make empiricist mistakes, and make the answers targeted. When encountering unusual questions, don’t be afraid, stay calm, fully trust yourself, and turn them into questions you are familiar with before answering.

(2) See clearly the location of the answer. When answering questions, you must clearly see the location of each question on the answer sheet, otherwise your work will be in vain.

(3) The paper should be neat and tidy, and the answer language should be standardized. Neat handwriting and neat paper surface will invisibly give some impression points to the teacher who corrects the paper. The language should be concise when answering questions, but this does not mean simple, nor can it just list big and empty vocabulary without targeted and effective answers.

(4) Adjust your emotions in a timely manner. After passing the first math test, don’t correct the answers. No matter what, you have already turned the page. Don’t affect your emotions. The gain outweighs the loss!

In short, everything remains unchanged. This "Zong" is our core point of view, main knowledge, our problem-solving ideas and thinking, and our heart of constant struggle!

May we use our dreams as horses and live up to our time!

History

Guo Wei, a history teacher at Zhengzhou No. 8 Middle School, has taught for 17 years. He is a member of the Zhengzhou Middle School History Teaching and Research Center Group. He has won the second prize for national quality history courses and participated in the compilation of the book "Unified History Textbooks·Teaching Design and Guidance".

At this critical moment of sprint review, everyone must pay attention to the following points:

1. Lay a solid foundation, check for omissions and fill in the gaps

Lay a solid foundation The important way is to return to the teaching materials, with the purpose of checking for omissions and filling them. Pay attention to understanding important historical concepts, familiarize yourself with the theme of each unit, grasp the main points, and form an overall grasp of the textbook. Do the basic questions well and grasp the main battlefield for scoring. The history subject adopts the form of open-book examination, so it is very important to master the basic knowledge of textbooks proficiently. We cannot talk about abilities and skills that are divorced from basic knowledge. At the same time, consolidate through less but more precise exercises and maintain a good problem-solving state. Or, go through the previous wrong questions. Such review will yield unexpected results.

2. Pay attention to hot issues.

One of the characteristics of the history subject in the High School Entrance Examination is that it reflects the educational function of the history subject, which requires students to observe, think, and understand historical things and historical phenomena in conjunction with the times. Therefore, paying attention to social reality, paying attention to social hot spots, and paying attention to the function of learning from history in the history discipline is a key point that needs to be paid attention to in review.

Such as anniversary events: 2021 is the 110th anniversary of the Revolution of 1911, the 100th anniversary of the founding of the Communist Party of China, etc.; hot issues over the years: national defense issues, diplomatic issues, the history of great powers, etc.; hot social issues of people's livelihood: poverty alleviation issues, the new crown epidemic Epidemic issues; energy issues, sustainable development issues of global concern, etc.

3. Pay attention to the new requirements and new developments in this year’s exam

(1) Based on the adjustment of the teaching content of the unified textbook, combined with the learning requirements that attach great importance to traditional culture in recent years, ancient history Partially increase the test weight, reaching 10 points in 2020 (3 points for ancient Chinese history, 2 points for ancient world history, 21 questions for 5 points). The main test content has developed from ancient science and technology and culture to foreign exchanges, ancient politics and other fields. It will reach 30% in 2021.

(2) The field of examination is broadened and is no longer limited to ancient science and technology culture. In 2019, the political field was tested, such as question 2: Qin Dynasty’s measures to consolidate unification. In 2020, ethnic exchanges were tested. For example, in question 3, the opening of the Silk Road promoted the exchange of species in the Western Regions and the Central Plains. The multiple-choice part focuses on examining the achievements of ancient material civilization, political civilization, and spiritual civilization, as well as ethnic exchanges and the exchanges between ancient Chinese and Western civilizations.

4. Pay attention to the relevant skills and essentials for answering questions

(1) Multiple choice questions: Review two elements. Whether it is a general type of single multiple choice question or a thematic multiple choice question, two elements must be reviewed, namely: conditional restrictions and the subject content of the question.

Conditional restrictions generally include time restrictions, location (or country) restrictions, field (including politics, economics, military, diplomacy, ideological modernization, etc.) restrictions, character restrictions (such as Emperor Taizong of the Tang Dynasty), etc. As far as time limits are concerned, there are usually four situations. One is that there is a clear time limit, such as the 1940s and 1950s, 1861, etc.; the other is that there is an upper limit but no lower limit, such as the centralized system since the Qin Dynasty. development; third, there is a lower limit but no upper limit, such as the prominent characteristics of my country's foreign relations before the mid-Ming Dynasty; fourth, neither the upper limit nor the lower limit is clear, such as the bourgeois revolution period, the Revolution of 1911, etc. When answering time-limited questions, you must accurately judge the upper and lower time limits based on historical knowledge.

The subject of the answer refers to the object of thought, which is what the person asking you to answer is. After reviewing this requirement clearly, the direction of choice is determined. Topic-style multiple-choice questions, each question has a different answer topic. The subject content of the test can be the causes, content, characteristics, nature, results, impact, etc. of historical things.

(2) Non-choice questions - material analysis questions

Grasp "one, two, three"

"One" refers to "a premise", That is, "to understand and understand the materials (especially charts and data)", you must clarify the main concepts and the main issues explained, and then figure out how the materials or data display the concepts and explain the problems.

"Two" refers to the "two principles", namely "fully obtain and utilize effective information" and "based on materials and contact textbooks". The first is to "fully obtain and utilize effective information." The so-called "effective information" refers to the content related to the question, which is often the center or theme of the material. If valid information is not discovered, the requirements of the question cannot be completed well and the score will be affected. The second is "based on materials and contacting textbooks". The perspective of the problem presented by the materials is not necessarily exactly the same as that of the textbook. For example, for a certain historical event, the textbook may mainly describe its positive side, while the material may show its limitations. It is necessary to contact the textbook, and the content reflected in the material should be Connect with the relevant knowledge learned in the textbook, and use the knowledge and viewpoints learned to comment and analyze.

"Three" refers to the "three steps" in constructing the answer to the question. That is, "first look" to see how many questions there are; "second search" to find out the required answer directions and restrictions in the questions; "three answers" to organize answers according to the questions. When organizing answers, use "serialization", such as: ①②③.

I hope the above relevant content will be helpful to everyone, and I wish the students excellent results.

Chemistry

Lin Jing, leader of the chemistry teaching and research team of Zhengzhou No. 8 Middle School, senior primary and secondary school teacher, winner of the Henan Province May 1st Labor Medal, Henan Province Teaching Skills Special Award, Zhengzhou City Education He is an advanced individual in teaching and has won many provincial and municipal open course awards.

1. Proposition Principle

1. The Chemistry Proposition of Henan Province has always adhered to the idea of ??seeking progress while maintaining stability, and developing new ideas while advancing. With the basic idea of ??"paying attention to the foundation, paying attention to inquiry, and connecting with reality", the propositions are strictly based on the "Curriculum Standards" and highlight the guiding, basic, innovative and contemporary nature of the propositions.

2. There are no significant changes in the test time, question types, question volume, and scores this year, but the difficulty coefficient of the questions has been slightly adjusted compared to last year. The difficulty ratio of test questions in 2020 is 7:2:1, and in 2021 it is 6:2:2. The difficulty coefficient has also changed slightly from last year, with the difficulty coefficient in 2021 ranging from 0.55 to 0.65. From this information, it seems that the difficulty of this year’s questions will be slightly higher. The 2020 proposition takes into account the impact of the epidemic on normal teaching, the delay in admissions and other factors, and has certain particularities. This year's admissions proposition should be comparable to that in 2019.

3. Henan Province’s winning proposition is closely integrated with the background of the times and highlights the local characteristics of Henan. For example, Henan is a major agricultural province and has a rich cultural and historical background. In daily life, we should not only strengthen our understanding of knowledge, but also develop a pair of discerning eyes, look at things around us from a chemical perspective, analyze some news events with scientific thinking, and let chemistry go out of textbooks. For example, Academician Yuan Longping's hybrid rice technology has solved the problem of eating for many people. Do you know what major nutrients rice can ultimately provide us with? In addition to genetic technology, what other chemical methods can increase production?

2. Review and prepare for the exam

1. Return to the textbook and pay attention to the basics. The 60 basic questions in the entrance examination questions cover all the units in the first and second volumes of the textbook. During the review process, students must remember to return to the textbook from time to time and learn to read. For example, if there is a choice between trace elements and major elements in the test questions, we can open page 97 of the next textbook to check the chart. To explore the composition experiment of methane, we can review the three experiments of candle burning, hydrogen burning and methane burning in the textbook. They all involve the operation of covering a beaker above the flame to understand a method of exploring the composition of matter. You can also do the after-school exercises in the textbook. For example, question 7 on page 123 of the previous textbook actually involves the transformation relationship between quicklime, slaked lime and calcium carbonate. If you do this question now during the review period, you can get a more complete picture. To understand it from the knowledge system and perspective.

2. Make good use of "Analysis and Detection". "Analysis and Detection" is the vane and important reference for successful entrance examination questions. The questions in the previous volume completely cover all knowledge points and various test points. After students have completed it carefully, they can then pick out the wrong questions, change the form, and do it again. They can also make calculations, solubility curves, micro-experiments or digital experiments into small topics. The 14 questions may be difficult for some students. You can find a time period to focus on solving the 14 questions in the 16 sets of test papers in the first and second volumes, and you may be able to break through the problem-solving ideas and methods. Of course, it is not enough to just do the "Analysis and Detection" questions well. During the explanation process, the teacher will focus on teaching the methods of reading and reviewing questions and the formation of problem-solving ideas. While understanding these, students should also focus on improving their understanding of the questions. The extraction and effective analysis of textual information, numerical information, chart information, etc. allow myself and the proposition teacher to be excited and excited in thinking, and can often easily write the correct answer.

3. Thematic training and simulation training. In the last stage, through special topic training and simulation training of set papers, scientific question-taking strategies can be formed, a stable question-taking rhythm can be cultivated, good answering habits can be consolidated, and there will be certain progress in performance. It is recommended that students choose the examination questions from the past five years, complete them carefully within the specified time, and evaluate the scores after the revision. I believe you will see your continuous progress and your grades gradually improving.

4. Relax your mind and be confident.

In the final stage, everyone has a certain amount of anxiety. Students should face the errors and scores in the test paper objectively and calmly, seek help and guidance in learning and thinking from the teacher, and have a more positive attitude and a more stable mentality. Countdown to the hit.

In the final stage of the subject of chemistry, it has reached a point where quantitative changes lead to qualitative changes. As long as the review efficiency is improved and the learning results are consolidated, I believe that students will be able to achieve satisfactory results. I wish all candidates success!
