Shaanxi college entrance examination mathematics examination paper analysis is as follows:
The main structure and problem setting are relatively stable.
First of all, compared with the recent 1 year, the total score of the large-scale investigation remains unchanged.
Among them, there is one more multiple-choice question in solid geometry and one less fill-in-the-blank question in probability statistics; Increase the investigation of three views and linear programming; Especially linear programming, which is the first investigation in Mathematics Volume 2 in recent 3 years. The knowledge points that have not been investigated for three consecutive years are still: binomial theorem, definite integral and so on.
Secondly, it highlights the value of backbone knowledge.
In this paper, we can see that solid geometry and analytic geometry have been strengthened; Functions and derivatives; Solve the scores of core knowledge such as triangle and trigonometric function, probability and statistics. Little change; The score of the series of exams has not changed, and it is still only 10, and the science exam in 2022 is also 10. However, the distribution of the two questions this year is slightly lower, and the difficulty is slightly improved.
According to: 2020 national examination 17 questions examine the solution triangle (Shaanxi Province uses the national volume 2), 202 1 questions 17 questions examine the order; In 2022 17, the triangle is examined, so in 2023, the series is examined; This is different from the training direction given by many essay papers, focusing on the order of numbers.
Not only did I not test the series, but I also learned about triangles. I gave probability statistics to the original fixed position of triangle or series problem 17, which reduced the amount of reading information and changed it. The location of the triangle solution test is 18.
This tells us that which paragraph is the finale is uncertain, which makes each paragraph need further discussion. Of course, there may be little change in the last year of the senior high school entrance examination area, but the new high school entrance examination paper is not necessarily the case.
Other topics have maintained the stability of the overall survey structure compared with the previous topics; For example, the title of 19 is solid geometry, the title of 20 is conic curve, and the title of 2 1 is the finale of derivative.
In addition, the questions 1, 2, 7 and 14 examined the complex number, set, permutation and combination, linear programming and so on. Questions 22 and 23, entitled multiple-choice questions, examined polar coordinates, parametric equations and inequalities respectively. In 2023, the national B-volume science mathematics test questions were slightly less difficult than last year.
