选择题是客观型试题,具有知识覆盖面广、形式灵活多变、推理较多、计算量小的特点,高考物理选择题注重基础性,增强综合性,体现时代气息,在注重考查基础知识、技能、方法的同时加大了对能力考查的力度。一、直接判断法根据所学的物理概念、规律、定理等直接判断,得出正确的答案。这种方法一般适用于基本不需要推理的常识性知识题目,这些题目主要考查考生对物理识记内容的记忆和理解程度。例1(2012年全国新课标卷改编)伽利略根据小球在斜面上运动的实验和理想实验,提出了惯性的概念,从而奠定了牛顿力学的基础。早期物理学家关于惯性有下列说法,其中正确的是()
Multiple-choice questions are objective questions, with wide knowledge coverage, flexible forms, more reasoning and less computation. The multiple-choice questions in the college entrance examination focus on basic topics, enhance comprehensiveness, reflect the flavor of the times, pay attention to the examination of basic knowledge and skills At the same time, the method increases the strength of the ability test. First, the direct judgment method According to the study of the physical concepts, laws, theorems and other direct judgments, come to the correct answer. This method is generally applicable to common-sense topics that do not require inference. The topics mainly examine the memory and comprehension of the candidate’s content. Example 1 (2012 National New Curriculum Scroll) Galileo put forward the concept of inertia based on the experiment and ideal experiment of the ball moving on the slope, which laid the foundation for Newtonian mechanics. Early physicists on the inertia of the following statement, of which the correct is ()
