(A) the arithmetic part
1. The range of this part: (1) Integer: Integer and its operation, divisibility, common multiple, common divisor, odd number, even number, prime number and composite number; (2) Fractions, decimals and percentages; (3) Proportion and specific gravity; (4) Number axis and absolute value.
2. The focus of this part: percentage, ratio and proportion, absolute value.
3. This part of the examination: generally 3-9 questions will be examined, and 20 10 will examine 8 questions.
4. The focus of this part of the content review is to understand the concepts and clarify the connections and differences between them. It seems simple, but many candidates lose points on simple topics every year, so the simple content should be carefully reviewed.
(2) Algebra
1. The scope of this part: (1) Algebraic expressions: algebraic expressions and their operations, factorization and factorization of algebraic expressions; (2) Fraction and its operation; (3) Functions: sets, unary quadratic functions and their images, exponential functions and logarithmic functions; (4) Algebraic equations: one-dimensional linear equations, one-dimensional quadratic equations and two-dimensional linear equations; (5) Inequality: the nature of inequality, mean inequality and inequality solution; (6) Series, arithmetic progression, geometric progression.
2. This part focuses on: unary quadratic function and its image, unary quadratic equation, binary linear equations, unary quadratic inequality, inequality solution, arithmetic progression, geometric series, etc.
3. Examination in this part: This part will generally examine the 4- 12 topic and the 20 10 middle 10 topic.
4. Emphasis of this review: (1) In algebraic expressions and fractions, the basic knowledge of concepts, formulas, principles, laws and other numbers, as well as the ability to perform correct operations and deformations are mainly investigated; (2) In the function part that must be tested every year, we mainly investigate the quadratic function of one variable and its images, and then investigate the properties and comprehensive application of exponential function and logarithmic function; (3) In the part of equations and inequalities, it is a compulsory part every year, and the focus of the examination is the quadratic equation of one variable and Vieta theorem; (4) In the series, it is a compulsory part every year. The focus of the exam is the nature and comprehensive application of the series. The series is both important and difficult. We must attach importance to and strengthen the review of the series.
Generally speaking, the review of this part of the content can not only stay in the memory of concepts, formulas and properties, but more importantly, it is reflected in the examination of its comprehensive application.
(3) Geometry
1. The scope of this part: (1) Plane graphics: triangle, quadrilateral, circle and sector; (2) Space geometry: cuboid, cylinder and sphere; (3) Plane analytic geometry: plane rectangular coordinate system, equation of straight line and circle, distance formula between two points, and distance formula from point to straight line.
2. Emphasis of this part: triangle, circle and sector, cuboid, sphere, straight line equation and circle equation, etc.
3. Examination in this section: Generally, this section will examine 3-8 topics, and 20 10 will examine 4 topics.
4. This part focuses on the review: the plane graphics part mainly examines the calculation application after the combination of triangles, quadrilaterals, circles and other graphics; Solid geometry mainly examines the examinee's spatial imagination ability and the ability to quickly decompose or combine graphics; In plane analytic geometry, we focus on the relationship between points, lines and circles in the plane, which requires candidates to understand and skillfully master and use the analytic expressions of graphics.
data analysis
1. The range of this part: (1) Counting principle: addition principle, multiplication principle, permutation and permutation number, combination and combination number; (2) Data description: mean, variance and standard deviation, and graphic representation of data; (3) Probability: events and their simple operations, addition formula, multiplication formula, classical probability model and Bernoulli probability model.
2. Emphasis of this part: permutation and combination, average, classical probability and Bernoulli probability.
3. Examination in this section: Generally, this section will examine 3- 10, and 20 10 will examine 4 questions.
4. This part of the review focus: This part of the review focus is to understand the meaning of permutation and combination, and master the formula and nature of permutation and combination number. At the same time, the examination of permutation and combination sometimes permeates probability theory, so we should also master the concepts, definitions and relationships of several basic events very skillfully.
