Looking at the 20 15 Tianjin college entrance examination paper, the author generally feels that while introducing fresh elements, it also retains the characteristics of Tianjin's local stability. The questions are concise and lively, with distinctive features, and ordinary questions test the real kung fu. While examining the basic knowledge, pay attention to the examination of thinking methods and abilities. The overall layout of the test paper is designed from the perspective of comprehensiveness, applicability and innovation. The difficulty distribution gradient of the test questions is relatively gentle, and the scene setting of the test questions is reasonable, which is closely related to the topic selection of the teaching materials. Compared with 20 13, the overall difficulty of this year's test paper has increased slightly. Each type of test paper has a large number of basic questions, many of which are set at the intersection of a single knowledge point or the most basic knowledge. For example, the multiple-choice questions 1, 2, 3, 4, fill-in-the-blank questions 9, 10,1and 12 in the test paper are all. The examination paper also pays attention to ensure that the main contents supporting the mathematical knowledge system (such as trigonometric function and plane vector, probability statistics, solid geometry, analytic geometry, sequence and function and derivative) occupy a high proportion.
