First, examine the basics, change the situation, ask questions about science, and pay attention to innovation
The high examination questions have the characteristics of "emphasizing the foundation, emphasizing application, emphasizing current affairs and emphasizing life". Compared with previous years, it is still mainly based on the examination of basic knowledge, and there are not many ups and downs, and what has changed is the background material and the angle of questioning, which is often new. Question 15 sets a negative charge fixed above the ground metal plate situation, examines the students' deep understanding of the concepts of electric field strength, isostatic surface, electric potential energy, etc., new situations, real problems, reflects the key knowledge key examination, key knowledge annual examination, often tested and new; the 18th question allows the Nobel Prize in physics to enter the students' field of vision, reflecting cutting-edge scientific research problems, cutting-edge physics problems, close to current events in physics, the starting point is very high and the landing point is very low, examining the application of Kepler's third law and the law of universal gravitation. Question 19 tests students' ability to solve problems through classical situation analysis and analysis of kinetic energy theorem. Question 20 designs the motion scenarios of charged particles with different specific loads in a uniform electric field, and tests students' mastery of the laws of flat thrown motion.
Second, closely follow the requirements of the college entrance examination propositions, strengthen the ability and literacy orientation
The proposition requirements of the 2021 college entrance examination clearly point out that the propositions must reflect the new spirit and new exposition of the Nineteenth National Congress and the plenary sessions of each session, embody the educational function and political mission of the college entrance examination of "strengthening the education of the core value system" and "enhancing the social sense of students", and adhere to the innovative thinking and learning ability examination to infiltrate the whole process of the proposition, implement the propositional requirements of "heavy thinking, heavy application, and heavy innovation", so that the college entrance examination will shift from "answering test questions" to "solving problems".
Question 21 through the familiar model - plate model, different presentation methods, gives the tensile force with time change image and board acceleration with time change image, students need to combine the model comprehensive analysis of the characteristics of the two images, mining hidden conditions, so as to establish the entire motion process of blocks and planks picture, and extract key information from the image according to the physical laws for rigorous logical reasoning, the students' information processing ability, reasoning ability, analysis and comprehensive ability requirements are high In fact, it is an examination of the penetrating power and profundity of students' thinking. Question 25 innovates the situation in which the conventional metal rod moves on the conductor frame, presenting the situation in which the conductor frame and the metal rod slide on the slope through the magnetic field area, the situation is complex, the research object, the research process and the force situation are complex, the calculation amount is large, the calculation is complex, the comprehensive ability of the student analysis is high, and the ability to solve problems in complex situations is examined.
Third, reflect the national conditions, fair and just, to familiarize the candidates, directly hit the weak ribs
The so-called "familiar candidates" is to use familiar knowledge in familiar problem situations to set up unfamiliar question angles, such questions can test the ability of students, is the candidate's group "weakness".
Question 22 of the familiar flat throw motion experiment by transforming the experimental conditions, the use of stroboscopic photography method to transform the known conditions, thereby changing the angle of the initial speed of the flat throw, by setting a new problem, gravitational acceleration, the examination is still the student's familiar flat throw motion law, but the student will be affected by the mindset, resulting in confusion. The 23rd question is the familiar experiment "Determination of the Electromotive Force and Internal Resistance of the Power Supply", a test of the law of the parallel circuit; the second test of the experimental principle, students in combination with the circuit diagram according to the ohm law of the closed circuit to write out the relationship between the measured quantity, customarily do not consider the influence of the voltmeter internal resistance; the ability to use image processing data, the need to convert the relationship between the measurement amount U and R into a function form, which is the soft underbelly of most students; the analysis and calculation of the experimental error of the fourth exam. Often students will only realize their previous mistakes when they do this step. This experimental question is set up layer by layer, interlocking, each question must stop a group of candidates, only students with innovative spirit, practical ability, and real analysis and research of the experiment can go to the end.

In the test questions, a large number of information presented through charts is required to be based on the material properties, experimental facts, experimental data and their relevant laws, to do reasonable and well-founded analysis, reasoning, judgment or calculation, mainly to examine the candidates' ability to accept, absorb and integrate information, the ability to analyze and solve problems, the ability to analyze and explore, in line with the requirements of the college entrance examination outline for the candidate's ability, highlight the ability examination, highlight the selection function of the college entrance examination. For example, question 12 uses the schematic diagram of the electrolytic device to provide information to examine electrochemistry knowledge, and question 13 provides a graph of the change of cation concentration with hydrogen ion concentration in saturated solutions of insoluble salts, requiring candidates to derive the ionization constant of monolithic weak acids and the solubility product constant of poorly soluble electrolytes through analysis of the data in the graph, and solve the problem one by one through analytical reasoning. Question 26 inorganic chemical process question, requiring candidates to use the chart information provided in the question, combined with relevant knowledge to solve practical problems, the 28th question uses the relationship between the logarithm of the partial pressure balance constant and the reciprocal of temperature, requiring students to obtain information and analyze and solve problems.
4. Pay attention to the creation of situations and highlight the sense of innovation
The test questions attach importance to the creation of real situations, the test questions take the materials from the production of scientific research as the background, take the real problems as the carrier, and examine the necessary knowledge and key abilities, and the background materials are unfamiliar or even scientific and technological frontier content that is not in the textbook and the examination syllabus. The test questions attach importance to the innovation of thinking, pay attention to the inquiry of the problem-solving process, dilute the ready-made conclusions of the textbook, encourage students to have unique insights, be innovative but not different, and test students' innovative ability. Although these are taken every year, but the situation is different, the focus of the examination is different, the angle of examination is different, the requirements for ability are different, and the test questions highlight the reform of the college entrance examination by creating a situation, breaking the traditional examination method, changing the innovative way of asking questions, etc., which highlights the reform of the college entrance examination, pays attention to the ability to examine innovation, is conducive to cultivating and selecting innovative talents, and is also conducive to reflecting the fairness of the college entrance examination. For example, the 26th question, the inorganic chemical process question, takes the ironmaking high titanium slag as the raw material to recover titanium, aluminum, magnesium, etc. as the background, and guides students to use the existing knowledge to solve the problems of chemical equations, ion equations, chemical calculations, separation and purification from practice. The 27th experimental question, through the preparation of graphene oxide, examines the redox reaction, the name of the experimental instrument, the ion test, and the polyester operation method of precipitation washing. Question 28 will balance the logarithm of the constant with the reciprocal graph of temperature, and ask students to use the information in the graph to solve problems.
5. The test questions are relatively stable, and the difficulty is basically unchanged
Compared with the high examination questions in recent years, the question types and difficulty of the 2021 college entrance examination comprehensive chemistry test questions remain basically unchanged, and the hot spots of the examination are relatively concentrated, with certain similarities, which are expected and reasonable. For example, chemical experiments, organic chemistry basics, electrochemistry basics, inorganic chemical process questions, chemical reaction principles and other topics are tested every year, often new. The test questions are moderately difficult, in line with the actual situation of students, have a good degree of differentiation, and meet the requirements of the college entrance examination outline and chemistry course standards. Most chemistry questions are difficult to find exactly the same questions as in the review materials, avoiding "guessing the question". Candidates who have mastered the necessary knowledge and key abilities, solid basic skills, and are good at flexibility and flexibility can be solved smoothly, while it is difficult to solve for candidates who are conformist, conformist, simple repetition, and rote memorization. This is conducive to the selection of outstanding students with development potential, fully reflects the selection function and fairness principle of the college entrance examination, avoids rote memorization and mechanical brushing, and better guides the teaching of chemistry in middle schools.
6. Pay attention to the comprehensiveness of problems and examine the comprehensive application ability
The chemistry test questions of the college entrance examination attach importance to the comprehensiveness of the problem, pay attention to the comprehensive application of knowledge, pay attention to the internal relationship and discipline system of the examination knowledge, especially pay attention to the "hidden connection" between the subject content, fully examine the potential of students, and test the candidate's ability to use the knowledge learned to transfer information and logical reasoning, so as to solve practical problems. For example, question 26 requires candidates to comprehensively analyze the entire process flow, and examine chemical experiments, elemental compounds, redox reactions, and chemical calculations based on the material conversion relationship in the process of reasoning about the nature of the substance. Question 27 takes the preparation of substances as the background, and fully examines the name and function of the instrument, experimental operation, the role of reagents, ion testing and other important chemical experimental knowledge and important elemental compound knowledge.
7. Close to the actual production, highlight the application of learning

In the chemistry test questions, there are some real situation materials that do not appear in the textbook and have not been seen by students, and come from the reality of production or life, using chemical knowledge to solve practical problems, so that chemistry can serve human society, contribute to social development, and avoid turning chemistry learning into paper. For example, the background material for questions 7, 10, 12, 26, 27, and 28 basically comes from the frontiers of production, life and technology, requiring candidates to use chemical knowledge and principles to solve practical problems.
8. Attach importance to experimental assessment and highlight the characteristics of the discipline
There are many questions directly or indirectly involving chemical experiments in the college entrance examination chemistry tests, and the basic methods and skills of chemical experiments are emphasized, and students are guided to pay attention to chemical experiments. In the process of solving chemical problems, we pay attention to guiding candidates to use chemical principles and scientific methods to design and evaluate, which reflects the value of the discipline and highlights the characteristics and charm of the chemical discipline. For example, questions 8, 26 and 27 fully test the basic knowledge and basic skills of chemical experiments.
9. Pay attention to chemical thinking and weaken mathematical calculations
The chemical calculation in the test questions mainly involves the calculation of concentration, chemical equation, chemical equilibrium, redox reaction, pH calculation, unit cell calculation, etc., the calculation questions focus on the examination of chemical reasoning process, the use of mathematical tools and mathematical calculation requirements are reduced, some questions even only need to list the formula, do not require the calculation results. For example, the calculation of the equilibrium constant of the iodine monochloride decomposition reaction in question 28 and the calculation of the spatial occupancy of the unit cell in question 35 only require the student to list the calculation formula.
10. The selected test questions remain stable and students are easy to play
The two selected questions of chemistry are strictly in accordance with the requirements of the syllabus, carried out in modules, and the implementation of excessive and limited questions gives students enough room for choice, which can give full play to students' potential and personality strengths. If students have solid basic skills and choose a topic that suits them, it is not difficult to score. The form of the 35th question examination is the same as in previous years, the test point is fragmented, there is basically no correlation between the sub-questions, and the hot knowledge in the structure and properties of matter is examined, such as extranuclear electron arrangement, chemical bond comparison judgment, electronegativity, atomic structure and properties, chemical bond type, chemical bond and hydrogen bond, molecular structure and properties, unit cell calculation, etc. The 36th question is based on the organic synthesis route as the background, examining the organic compound naming, reaction type judgment, equation writing, isomer judgment and other organic chemistry core content, the topic pays attention to the network of knowledge, attaches importance to the comprehensive application of knowledge, the problems are interlocked, the relationship between the front and back is relatively close, and the comprehensiveness is strong.
In short, the 2021 college entrance examination chemistry test questions not only maintain the characteristics of the college entrance examination chemistry test questions in recent years, but also show their own characteristics. The test questions emphasize the educational function of "Lide Tree People", highlight the core function of "service selection", reflect the guiding role of "guiding teaching", strengthen the ability intention and the core literacy orientation of the discipline, reflect the continuity and stability of the high examination questions, which is conducive to the selection of new students in colleges and universities, and also helps to promote secondary school quality education, promote teaching reform and college entrance examination reform.

Reflect the core functions of the college entrance examination
Achieve a smooth transition to reform
As the reform of the college entrance examination continues to enter the deep water area, the 2021 college entrance examination biology national volume has a complex pattern of four sets of test questions, namely the national volume A, the national volume B, the new college entrance examination 1 volume, and the new college entrance examination 2 volumes. Overall, the 2021 College Entrance Examination Biology National Volume B test questions take the college entrance examination evaluation system as the preamble pointer, reflecting the disciplinary education function of "Lide Tree People", while paying attention to scientific material selection and guidance teaching. The test questions are based on stability, and the question types, styles, and situation choices are close to the students' cognitive level, paying attention to the comprehensive examination of basic and applied, which is conducive to the smooth transition of the new college entrance examination reform.
First, infiltrate traditional culture and reflect the education of disciplines
China's excellent traditional culture and outstanding achievements are the spiritual lifeblood and source of strength for realizing the "Chinese Dream". Question 37 of the National Volume B of the 2021 College Entrance Examination Biology organically integrates the long history of making soy sauce by the ancients of China with the scientific cognition of modern microorganisms, especially mentioning the operational requirements and scientific principles of the "Aspergillus oryzae fermentation process" in industrial production, so that students can appreciate the extraordinary wisdom of the ancient working people and the long-standing and profound Chinese excellent traditional culture. Guide students to identify with their own ideological culture and value system, strengthen cultural self-confidence, enhance national pride, and establish the responsibility of forging ahead and fighting for the socialist cause of the motherland for life.
Second, examine the thinking and cognition, and serve the selection of the college entrance examination
Thinking cognitive ability is one of the three key ability groups established in the college entrance examination evaluation system, which mainly includes the thinking ability of inductive generalization, deductive reasoning, dialectical thinking, and critical thinking that students show when facing new situations and solving new problems. The 2021 College Entrance Examination Biology National Volume B Question 5 takes the Griffith Diplococcus pneumoniae transformation experiment that students are more familiar with as the context, and examines students' deep cognition of the nature and transformation of the experiment by using critical thinking and dialectical thinking on the basis of perceptual cognition of experimental phenomena and results. Question 6 examines the genetic laws of n different traits controlled by n pairs of independently inherited genes, which requires students to use inductive generalization and deductive reasoning to conduct further theoretical exploration on the basis of being familiar with the transmission laws of two pairs of genetic traits. Solving such problems has relatively high requirements for thinking and cognitive ability, which reflects the important function of college entrance examination service selection.
Third, highlight the proposition of "four wings" and achieve a smooth transition
The "four wings" in the college entrance examination evaluation system attach importance to evaluating candidates from the perspective of basic, comprehensive, applied and innovative. Questions 4 and 31 of the 2021 College Entrance Examination Biology National Volume B respectively examined the basic knowledge of the transmission of excitement between neurons, the production of related hormones and physiological effects, and students with a solid foundation were easy to answer accurately. Question 3 deals with the form, function, relationship with metabolism of water, and changes in water during aerobic respiration, and examines students' understanding of the relevant knowledge with "water" as the core. Questions 3, 29, 30 and 37 are all based on the background of production and practical application materials, so that students can fully perceive the application value of the knowledge they have learned, and guide students from solving problems to solving problems. The whole set of test questions did not appear partial questions, strange questions, and the amount of reading of the stem was not large, which fully reflected the humanistic care for students and was conducive to the smooth transition of the new and old college entrance examinations.

The 2021 college entrance examination national volume B biology test questions focus on the fundamental task of Lide tree people, rely on the college entrance examination evaluation system, and give play to the educational function of biology. The question type is generally stable, not biased, focused, moderately difficult, but highly flexible. Closely around the core concept, highlighting the basic and applicable. It aims to examine the students' mastery of basic knowledge and the development of the core literacy of biology disciplines, guide teachers to effectively use high school biology textbooks and "General High School Biology Curriculum Standards" in biology teaching, based on the discipline foundation, strengthen conceptual cognition, follow the laws of education, and focus on cultivating students' learning and inquiry ability; further integrate into social hotspots, reflect biology from life, and use it in life, and convey the concept of learning to apply.
(1) Understanding of core concepts, application of basic skills, highlighting the characteristics of biological disciplines.
This test focuses on the main knowledge such as cell division, cell metabolism, photosynthesis and respiration, the basic laws of heredity, the regulation of the life activities of organisms, and the interspecific relationships of ecology, highlighting the characteristics of biology.
6 multiple choice questions, the first 3 questions are compulsory 1 content, respectively, examined the characteristics of chromosomes and DNA changes in mitosis, the role of various reagents in biological experiments, the metabolism of water in cells, focusing on the recognition and understanding of basic knowledge, but also reflects the college entrance examination's emphasis on the concept of life in the core literacy of biology; the 4th course is titled Compulsory 3 content, which examines the conduction and transmission characteristics of excitement in neuromodulation, reflecting the guiding role of the college entrance examination in paying attention to life and health; the 5th course is titled Compulsory 2 Content. In vivo transformation experiments for Streptococcus pneumoniae are examined, which advocates for students to focus on their own health. The first 5 courses are titled Basic Knowledge of Textbooks, which are less difficult, create realistic situations, set problems, and fully highlight the function of educating people in the college entrance examination. Question 6, which is a compulsory second course, examines the student's application of Mendelian's law of free combination, which is an examination of the student's scientific thinking.
(2) Theory guides practice, practice draws conclusions, and cultivates students' key abilities.
One of the concepts of the curriculum standard is to "pay attention to the connection between disciplines and new technologies, enhance students' analytical ability, and develop students' application ability". Question 29 is still in accordance with the practice of the comprehensive application of photosynthesis and respiration, students need to master its basic concepts, basic processes, basic principles and other core theories at the same time, added new knowledge materials, such as white weather holes closed at night open new situations, the last question requires students to be able to design experimental schemes to verify the relevant knowledge, requiring students to have the key ability to understand problems, analyze problems, and solve problems when facing life practices related to disciplines or learning to explore problem situations.
Question 30 examines the competitive relationship between species in ecology in compulsory third course, and in combination with the existing experimental materials in the textbook such as large grasshoppers and double-small nucleated grasshoppers, it also gives a new concept - competitive exclusion, requiring students to use the current learning, carry out bird research accordingly, and draw research conclusions. In this way, students' ability to understand and apply core concepts (competition) and transfer and expand, and form the concept of life of biological co-evolution. Through this question, students can be guided to observe more biological phenomena in life, use the knowledge they have learned or explain the corresponding problems according to experiments, and also advocate that teachers should quote more life examples and life phenomena in biology teaching to cultivate students' ability to apply what they have learned and apply analysis.
In short, this year's test questions are moderately difficult, based on the basics, highlighting the backbone, intentional ability, advocating innovation, focusing on the students' mastery of basic knowledge and basic skills in the new situation, as well as the ability to comprehensively use biological knowledge to analyze and solve practical problems. At the same time, the requirements for candidates to carefully review the questions and accurately and standardize the answers are higher, which can better examine the candidates' biological science literacy, reflecting the concept and requirements of the new curriculum standards.
