How to evaluate the 20021National College Entrance Examination B Mathematics (both arts and sciences)? How difficult is this year's topic? What changes have been made?
The examination direction is flexible and comprehensive, and the difficulty is improved and changed;

1, the integration of tradition and innovation

202 1 national volume b mathematics test questions continue the concern and investigation of mathematics culture and practice, and also add some ill-structured test questions.

For example, 9 questions in science mathematics are typical ill-structured questions. Using twice similar triangles and bisection ratio theorem to deal with the equation of side length similarity ratio, it is easy to get the answer. In addition, you can also substitute special values to quickly eliminate interference options.

2. Pay attention to the actual situation and production and life.

The ninth question of science mathematics is based on the example of measuring the height of the island in the book "Island Calculation", with real situations, emphasizing the integration of theory with practice and solving practical problems by mathematical methods.

Matters needing attention in college entrance examination mathematics paper examination

1, expand the foundation and strengthen the general method.

The college entrance examination examines the basic knowledge comprehensively and highlights the key points. Grasping the foundation is to pay attention to the review of teaching materials, especially to the formation process of concepts, formulas, rules and theorems, to the limited scope of conditions and conclusions in use, to understand the typical role of examples in teaching materials, not only to do exercises in teaching materials, but also to deeply understand the mathematical thinking methods embodied in solving problems.

2. Read the exam instructions carefully to reduce the ineffectiveness.

When practicing or conducting mock exams at ordinary times, we should pay attention to cultivating test emotions and forming good habits. First of all, carefully understand the exam instructions and do as required. Compare the illustrated examples to learn how to examine knowledge points and understand the requirements for each knowledge. Never train the requirements for knowledge.
