20 1 1 The changes in the description of the entrance examination of Mathematics (Jiangsu Volume) have the following changes compared with that of 20 10: 1. Delete the "sum-difference product, sum-difference product and half-angle formula" of A-level test center (compulsory 4); 2. remove the "fixed point" of the A-level test center (elective series 2). 20 1 1 The requirements for knowledge examination in the description of Mathematics of National College Entrance Examination (Jiangsu Volume) are divided into three levels: understanding (a), understanding (b) and mastering (c). There are 29 A-level test sites, 36 B-level test sites and 8 C-level test sites. Additional questions include 1 1 A-level test sites, 36 B-level test sites and no C-level test sites. The full mark of the required part of the test paper is 160, and the test paper consists of two parts: fill-in-the-blank questions and solution questions, of which the fill-in-the-blank questions are 14, accounting for about 70 points; Answer the sixth question, accounting for about 90 points, and the examination time is 120 minutes. Required questions are composed of easy questions, intermediate questions and difficult questions. The proportion of easy questions, medium questions and difficult questions in the test paper is roughly 4: 4: 2. The additional questions have a full score of 40 points and consist of 4 solutions. The examination time is 30 minutes. Additional questions are composed of easy questions, medium questions and difficult questions, and the ratio is about 5: 4: 1. Suggestion for preparing for the exam (1) Control the depth and difficulty according to the outline. Make clear the scale of each knowledge point, and do little or no useless work. Reasonable judgment of A, B and C test sites is the key. For example, C-level test sites may not necessarily be examined in difficult problems. 20 10 The examination of straight lines and circles in Jiangsu Mathematics College Entrance Examination is an example. For example, the hyperbola and parabola in the conic section are only A-level test sites in the required questions and do not need to be upgraded. (2) Pay close attention to double basics and pay attention to universality and generality. Don't engage in "digression" and "strange questions" in the review, and carefully understand the basic problem-solving ideas and methods in the textbook. (3) Cultivating ability and infiltrating mathematical thinking methods. In review, we should strengthen the training and cultivation of the following abilities: reading comprehension ability, written expression and communication ability, calculation ability and so on. (4) Strengthen the review of special topics and pay attention to the content of the connection between high school and university. Arrange the training difficulty of each module reasonably, pay attention to the additional questions, but don't blindly increase the training difficulty of the additional questions. Application questions are tested every year, so we can carefully study which mathematical models are established and which models are not tested. You can consider special review and training.
