20 17 Jiangsu college entrance examination mathematics has just ended. From the structure of the test paper, the traditional Jiangsu proposition style is generally maintained, with special emphasis on the examination of students' "three basics" ability, which basically meets the requirements of the test instructions, covering 8 C-level test sites and most B-level test sites required in the test instructions, taking into account the actual situation of middle schools, with a slight change in stability and a sense of innovation. It can not only be people-oriented, but also reflect the selection function of mathematics papers in the college entrance examination. The life system of test questions also pays attention to the diversity of solutions. Students can think and solve problems from multiple angles. This paper is equivalent to the papers of the past three years, but it is more difficult than the previous two years.

14 the overall structure of the fill-in-the-blank question is similar to that of previous years. The content of the last few questions has always been the question type of the final mock exam training, and the difficulty has spiraled up, which effectively enhances the students' self-confidence in the exam process and has a strong distinction! Among them, 13 examines the synthesis of straight line and circle, vector and inequality, which has certain discrimination, but it should not be too difficult to deal with if we strengthen the training of comprehensive ability at ordinary times; 14 questions examine the number of zeros in the function, which puts high demands on students' thinking of combining numbers with shapes. We have trained the general types of fill-in-the-blank questions, and the students' scores should be not low!
