今年高考理科综合共31题,满分300分,其中选择题24道,共144分;非选择题7大题,共156分。试题中理、化、生题量与各科教学大纲规定的课时比例大致相同,试题注重基础知识,以学科内综合为主,难度不大,有一定的区分度。试题情景新颖,灵活多变,源于课本,又不拘泥于课本,有效地考查了考生的综合分析能力,主要体现在以下几个方面: 一、密切联系社会生活、生产实际,考查考生的应用能力。许多试题以社会生活和科技应用的实际与理科知识相联系,设立情景,考查考生运用“双基”分析研究问题的能力,试题突出了以能力考查为主导的原则。例1 (第24题)电磁流量计广泛应用于测量可导电流体(如污水)在管中的流量(在单位时间内通过管
In this year’s college entrance examination, science subjects have a total of 31 questions, with a full score of 300 points, including 24 multiple-choice questions, a total of 144 points, and 7 non-choice questions, totaling 156 points. In the test, the proportions of the proportions of science, chemistry, and problem-solving and the syllabus for each subject are roughly the same, and the questions focus on the basic knowledge. The integration within the subject is not difficult and has a certain degree of differentiation. The examination scenario is novel, flexible and flexible. It stems from textbooks and is not rigidly adhered to textbooks. It effectively examines candidates’ comprehensive analytical abilities, and is mainly embodied in the following aspects: 1. Closely linking social life with actual production, and examining candidates’ applications ability. Many test questions are related to the actual and scientific knowledge of social life and science and technology applications. They set up scenarios to examine the examinees’ ability to use “dual bases” analysis to study problems. The test questions highlight the principle of taking ability examination as the leading factor. Example 1 (Item 24) Electromagnetic flowmeters are widely used to measure the flow of a conductive fluid (such as sewage) in a pipe (through a pipe in unit time
