Analysis of the National Science Mathematics Test Paper of Volume B in 2022 and the Answers
The life scale marked by ten years' cold window is indelible, and studying hard at desk can't be summarized by a sentence "let bygones be bygones" The college entrance examination is destined to be a colorful chapter in the book of students' lives. Next, I will bring you the 2022 national B-volume science mathematics test paper and the answer analysis. I hope it helps you. Welcome to read!
Analysis of the National Science Mathematics Test Paper of Volume B in 2022 and the Answers
Mathematical problem-solving skills in college entrance examination
1, the first is the topic selection, so as to be less but better. Only by solving high-quality and representative problems can we get twice the result with half the effort. However, the vast majority of students have not been able to distinguish and analyze the quality of the questions, so they need to choose exercises to review under the guidance of teachers to understand the form and difficulty of the college entrance examination questions.
2. Secondly, analyze the topic. Before you solve any math problem, you must analyze it first. Analysis is more important than more difficult topics. We know that solving mathematical problems is actually to build a bridge between known conditions and conclusions to be solved, that is, to reduce and eliminate these differences on the basis of analyzing the differences between known conditions and conclusions to be solved. Of course, in this process, it also reflects the proficiency and understanding of the basic knowledge of mathematics and the flexible application ability of mathematical methods. For example, many trigonometric problems can be solved by unifying angles, function names and structural forms, and the choice of trigonometric formulas is also the key to success.
3. Finally, summarize the topic. Solving problems is not the goal. We test our learning effect by solving problems, and find out the shortcomings in learning so as to improve and improve. So the summary after solving the problem is very important, which is a great opportunity for us to learn. For a complete theme, the following aspects need to be summarized:
In terms of knowledge, what concepts, theorems, formulas and other basic knowledge are involved in the topic, and how to apply these knowledge in the process of solving problems. ② Method: How to start, what problem-solving methods and skills are used, and whether they can be mastered and used skillfully. (3) Can the problem-solving process be summarized into several steps? (4) Can you summarize the questions and then master the general problem-solving methods of such questions?
Mathematics knowledge points of college entrance examination
1. There are nine chapters in college entrance examination mathematics, including function, sequence, trigonometric function, plane vector, inequality and solid geometry.
Mainly test functions and derivatives, which are the core plates of our whole high school stage. In this section, we focus on two aspects: the properties of the first function, including monotonicity and parity of the function; The second is the solution of function, focusing on quadratic function and higher order function, fractional function and some distribution problems, but this distribution also includes two analysis problems, namely the distribution of quadratic equation, which is the first plate.
Second, plane vectors and trigonometric functions.
Focus on three aspects: first, subtraction and evaluation; The other is to master formulas and five basic formulas. Secondly, the images and properties of trigonometric functions. This paper focuses on the properties of sine function and cosine function. Thirdly, the triangle is solved by sine theorem and cosine theorem. The difficulty is relatively small.
Third, the order.
This series focuses on two aspects: a common term; One is summation.
Fourthly, space vector and solid geometry, in which we focus on two aspects: one is proof; One is calculation.
Fifth, probability statistics.
This part mainly belongs to the category of mathematical application problems. Of course, we must master the following aspects: the first possible probability, the second event, the third independent event, and the probability of independent repeated events.
Sixth, analytic geometry.
This is a headache for us, and it is also a difficult and computationally intensive problem in the whole paper. Of course, for this kind of questions, I have summarized the following five types of frequently asked questions, including:
The positional relationship between straight lines and curves mentioned in the first category is the most testing content. Candidates should master its general methods;
The second kind of moving point problem we talk about;
The third category is the chord length problem;
The fourth category is symmetry, which was passed in the college entrance examination in 2008;
The fifth key question often feels thoughtful, but there is no answer.
Of course, what I'm saying here is that although this problem has a large amount of calculation, the reason for the large amount of calculation is often this reason, and the method we choose is not very appropriate. Therefore, in this chapter, we need to master a better algorithm to improve the accuracy of our questions, which is the sixth section we talked about.
Seventh, the issue of gambling axis.
Candidates should focus on learning the calculation method of inequality when preparing for the exam. Although it is difficult, I suggest that candidates grade the whole test paper in different parts, and don't leave blank. This is the core test site of the seven sections of the college entrance examination.
Summary of Mathematics Knowledge Points in Senior Three: Sampling Method
random sampling
brief introduction
Often used when the population is small, its main feature is to extract from the population one by one;
Advantages: simple operation.
Disadvantages: The overall size is too large to be realized.
way
draw lots
Generally speaking, the lottery method is to number the n individuals in the population, write the numbers on the digital labels, put the digital labels into a container, stir them evenly, and extract 1 digital labels from them every time, and extract them continuously for n times to get a sample with a capacity of n.
Random number method
In random sampling, another commonly used method is random number method, that is, random number table, random number dice or computer-generated random number are used for sampling.
group sampling
brief introduction
The main feature of stratified sampling is proportional stratified sampling, which is mainly used in the crowd, and there are obvious differences between individuals. * * * Similarity: the probability of each individual being drawn is equal to n/m.
definition
Generally speaking, when sampling, the population is divided into disjoint layers, and then a certain number of individuals are independently extracted from each layer according to a certain proportion, and the individuals extracted from each layer are combined as samples. This sampling method is stratified sampling.
Nested sampling method
definition
What is cluster sampling?
Cluster sampling is also called cluster sampling. It is to combine all the units in the population into several sets that do not cross each other and do not repeat each other, which are called groups; A sampling method in which samples are sampled in groups.
When cluster sampling is applied, each cluster is required to have good representativeness, that is, the differences between units within the cluster are large and the differences between groups are small.
merits and demerits
The advantages of cluster sampling are convenient implementation and saving money;
The disadvantage of cluster sampling is that the sampling error caused by large differences between different groups is often greater than that caused by simple random sampling.
Implementation steps
Firstly, the population is divided into group I, and then several groups are extracted from group I clock to investigate all individuals or units in these groups. The sampling process can be divided into the following steps:
Firstly, the label of clustering is determined.
Second, divide the whole into several non-overlapping parts, and each part is a group.
Third, according to the sample size, determine the number of groups to be extracted.
Fourthly, by using simple random sampling or systematic sampling method, the determined group number is extracted from the I group.
For example, investigate the situation of middle school students suffering from myopia and make statistics in the last class; Conduct product inspection; All products produced by 1h are sampled and inspected every 8 hours, etc.
Difference from stratified sampling
Cluster sampling and stratified sampling are similar in form, but quite different in fact.
Stratified sampling requires large differences between layers, small differences between individuals or units within layers, small differences between groups and large differences between individuals or units within groups;
The sample of stratified sampling consists of several units or individuals extracted from each layer, while cluster sampling is either cluster sampling or cluster sampling is not.
systematic sampling
definition
When there are many individuals in the group, it is more troublesome to adopt simple random sampling. At this time, the population can be divided into several balanced parts, and then an individual can be extracted from each part according to predetermined rules to get the required samples. This kind of sampling is called systematic sampling.
step
Generally speaking, if you want to extract a sample with a capacity of n from a population with a capacity of n, you can carry out systematic sampling according to the following steps:
Firstly, the n individuals in the population are numbered. Sometimes you can directly use your own number, such as student number, admission ticket number, house number, etc.
Determine the segmentation interval k and the number of segments. When N/n is an integer, take k = n/n;
In the first paragraph, the first individual number l is determined by simple random sampling;
Sampling according to certain rules. Usually, the interval k is added with L to get the second number of individuals, and then K is added to get the third number of individuals, and so on until the whole sample is obtained.

Is it difficult to take the 2022 exam? What's the difficulty?
Different from the college entrance examination, the examination questions in the senior high school entrance examination are set by all localities and the examination time is arranged by themselves, so the difficulty of the examination questions in the senior high school entrance examination is not consistent with the examination time. Up to now, the senior high school entrance examinations in some places have ended. Judging from the reaction of candidates, this year's senior high school entrance examination questions seem a bit difficult compared with previous years.
For example, in some places, the history test questions in the senior high school entrance examination are much more difficult for many candidates to reflect than last year. In some places, the math test questions in the senior high school entrance examination are also quite difficult. In short, just like this year's college entrance examination math exam, it always feels too difficult. It is difficult for ordinary students to get points on many topics, and it is really not easy to get high marks.
I met a relative's child yesterday and just finished the senior high school entrance examination. According to him, many questions in this year's senior high school entrance examination are very different from those I usually train. Suddenly I feel that I have learned nothing in the examination room, and those rote memorization things don't seem to be very useful. This child is not the only one who feels this way. I asked several children who took part in the senior high school entrance examination, and they all felt this way.
However, some netizens believe that the difficulty of the exam depends on who it is for. Many candidates think that math problems are too difficult and it is not easy to get high marks. Full marks 150, 70-80 are good enough. But you go and check, there are many candidates above 140. Are the exam questions really difficult for these candidates?
Therefore, it is not difficult to test questions in the senior high school entrance examination, depending on which candidates. For those who learn to bully, they have high IQ, flexible learning methods, quick response and good grades. No matter how difficult the test questions are, it is really a bit difficult for ordinary candidates. Then the mid-term exam becomes difficult. Where is the difficulty?
In fact, the college entrance examination was completely changed last year, and the weather vane has been very clear. The examination questions have come alive, mainly to examine the candidates' ability to transfer and use knowledge, not to memorize them by rote or to brush them mechanically. The senior high school entrance examination is no exception. The exam questions are flexible and changeable, and you can't just rely on rote memorization and mechanical brushing.
Therefore, the difficulty of the middle school entrance examination is not really difficult, but more and more lively. You can't answer questions directly according to the knowledge points you have learned by rote. You need to combine the knowledge points you have learned, extrapolate them, transfer them, analyze them comprehensively, use them flexibly and solve problems.
In a word, I think the entrance examination questions in recent years have not become difficult, but have changed their faces, and the questions are flexible and changeable. Such changes enlighten us that the teaching activities in primary and secondary schools should keep pace with the times, change concepts and methods, and change from focusing on imparting knowledge in the past to cultivating ability and core literacy.
The above is my humble opinion. I don't know what you think of this year's mid-term exam. How difficult is it? If you have any suggestions, please discuss and leave a message. For more information, please pay attention to Senior Teachers Teaching Chinese.
Comments on the Difficulty of Mathematics Examination Paper in Tongchuan Senior High School Entrance Examination in 2022
In 2022, the math test of Tongchuan senior high school entrance examination has ended. The following are comments on the math test paper for your reference only.
Analysis on the difficulty of mathematics examination paper in Tongchuan senior high school entrance examination
Based on basic knowledge, basic skills, basic ideas and basic activity experience, the whole volume innovates the multi-question examination method, and the new examination method makes the overall form of the test paper novel and the questions flexible. Question 22 changes the previous "using a linear function to solve practical problems" to "directly examining the related concepts of a linear function in the form of flowcharts and tables", focusing on the essence of the concept; Question 25 "Synthesis of Quadratic Function and Geometry" was changed to "Applying Quadratic Function to Solve Practical Problems", so that students can appreciate the application value of mathematics. The prototype of the new examination method can be found in the textbook, which not only highlights the examination of the essence of concepts, but also guides everyone to return to the textbook and pay attention to the study and understanding of mathematical concepts. At the same time, it also enhances students' sense of acquisition and accomplishment, enhances students' confidence in learning mathematics well, and highlights the requirement in the mathematics curriculum standard that "everyone can learn valuable mathematics and everyone can get necessary mathematics".
This set of questions presents the following new forms: the fourth question examines the concept of special quadrilateral in multiple-choice questions; 19 question examines the translation in the coordinate system; Examine the basic concepts and methods of regression in questions 22 and 25; After 2020, the second full volume did not have the geometric maximum and algebraic maximum that everyone liked. All these have broken the expectations of many teachers for this exam, further broken the previous propositional model of mathematics in the senior high school entrance examination in 2022, and reflected the determination of proposers to break the inherent model. Looking carefully, almost all the innovations in this set of papers can be found in textbooks, all of which point to the core knowledge and literacy of mathematics. From this point of view, this set of papers has played a very good teaching guidance role. We should take the textbook as the starting point, rethink the teaching objectives, choose appropriate teaching methods, and strive to tap the educational value and function contained in the textbook, so as to develop students' mathematical core literacy.
How to learn math well
1. To learn mathematics well, we must grasp three "basics": the basic concepts should be clear, the basic laws should be familiar, and the basic methods should be skilled.
After you finish the topic, you must sum it up carefully, so that you won't spend too much time and energy when you encounter similar problems in the future.
3. Have a comprehensive understanding of mathematical concepts, and don't generalize by partiality.

Mathematics learning skills
The foundation is very important
Do you feel that students who can get full marks in mathematics don't even have to read books? In fact, math experts pay more attention to the foundation. Mathematical formulas, properties of geometric figures, properties of functions, etc. , are the basis of mathematics learning, and even the quality of the foundation directly determines the level of mathematics scores in the senior high school entrance examination.
The wrong question book is very important.
Of all the subjects, mathematics is the most important one. We especially encourage you to sort out the wrong questions. There are some tips for wrong questions. That is, if you insist on sorting out the wrong questions at ordinary times, you will eventually get a lot of thick wrong questions. We can review regularly. For those who have a thorough grasp, you can mark them, so that you don't have to review them in the future, and it will be more efficient to use the wrong questions.
