近几年来,在各级各类的考试中,选择题的数量逐渐增加。这不单是由于选择题在形式上适应了标准化考试的要求,而是因为它本身所具有的优点。选择题能做到量多面广,考查知识全面。又能反映考生的知识水平,灵活运用知识的能力,分析、处理问题的思路和方法。选择题中多数题目是考查考生对基本概念和定理、定律的理解是否正确。因而有助于教学质量的提高。选择题阅卷迅速简便,准确无误,评分公平合理。颇受广大师生的欢迎。以下分别从五个方面谈谈如何解答物理选择题。 (一)要从物理学的基本概念和定理、定律出发选择答案,切不可乱猜。例1.以下七个小题可供选择的答案是: a.重力、斜面的弹力和料面的摩擦力; b.重力、斜面的弹力、斜面的摩擦力和下滑力; c.重力、斜面的弹力,斜面的摩擦力和平衡力;
In recent years, the number of multiple-choice questions has gradually increased in all types of examinations. This is not only due to the fact that multiple-choice questions formally adapt to the requirements of the standardized test, but because of its own advantages. The multiple-choice questions can be multi-faceted, comprehensive, and full of knowledge. Can reflect the examinee’s knowledge level, the ability to use the knowledge flexibly, analyze, deal with the problem idea and method. Most of the multiple-choice questions examine the candidate’s understanding of the basic concepts and theorems and laws. This contributes to the improvement of teaching quality. The selection of question marks is quick, simple, accurate, and fair and reasonable. Very popular with teachers and students. Here are five ways to talk about how to answer physical multiple choice questions. (1) Choose the answer from the basic concepts of physics, the theorem and the law, and must not guess. Example 1. The answers to the following seven questions are: a. Gravity, the elasticity of the slope, and the friction of the material surface; b. Gravity, the elastic force of the slope, the friction force of the slope, and the sliding force; c. Gravity, slope The elastic force, the friction and the balance of the slope;
