Talk about the basic characteristics of each part:
Collection: Investigate the basic ideas such as intersection, merger and replacement. This part is painful and abstract at first, but after learning it, it is nothing and the simplest part of the whole.
Let's talk about probability and linear programming. In this part, the investigation of probability is also relatively basic. The hardest thing is to test a conditional probability, and then linear programming is super simple. Generally, it is to solve a binary linear system of equations.
Programming is generally based on simple logical judgment. The form of the problem is a program flow chart, such as loop 100 times. This part is relatively novel. For high school students, because this is actually the basis of algorithms and computers (my major in college is computers), this part generally allows you to find a simple calculation. After reading the questions and seeing the cycle conditions clearly, you can write the answer directly.
Spatial entity set part: this part is basically solved by modeling with spatial entity coordinate system. As long as you choose the appropriate coordinate system and use vector calculation, you can calculate it. Don't worry about this part. Do more questions and you will be able to master them completely.
The above part is the simplest and most basic part of the whole college entrance examination paper. Let's talk about the more difficult part. Sequence is usually the most difficult problem in the exams in previous years, but now it is simplified by derivative. The correlation of series corresponds to the series problem of higher mathematics in universities, and it is also a super difficult part in universities, but the college entrance examination is very basic. Generally, the first problem solves the general formula, and the second problem solves an inequality problem.
Quadratic curve, including hyperbola, parabola, elliptic curve, etc. This part mainly focuses on calculation, so you need to exercise your calculation ability. This part should be calm and don't be anxious.
Derived questions, this part is the most difficult part of the whole college entrance examination at present. Derivative is the basis of higher mathematics. In recent years, high school mathematics has the knowledge to guide advanced mathematics and calculus, which generally appears as the finale. This part usually uses elementary methods to solve a theorem of higher mathematics, focusing on how thoroughly you understand the derivative idea, so it is time to examine intelligence and emotional intelligence. The second question is generally super difficult. If you don't plan to enter Tsinghua Peking University, you don't have to waste time on the second question.
Regarding the last three so-called high math problems, we can look at the solution methods of general formulas in higher mathematics series, which is very skillful. For a high school student, it's a bit difficult to push it out completely. We can just watch it and use it directly.
For derivative questions, if you have time, you can read the first volume of Advanced Mathematics to learn a lot of inspiration and thinking expansion, and then you can see how to do it with such questions. If you have no time or limited ability, you must listen carefully, and the more thorough you understand calculus, the better.
Finally, I wish you an ideal result. At the same time, the college entrance examination is not only about intelligence, but also about other aspects. Don't be short of themes, guard against arrogance and rashness, and be practical is the most important thing. If you can do the above, it is not a big problem to take the 985 exam.
