近年来的中考题中,规律探索性试题的比例逐年增大,这类物理试题,大致具有如下特点:①有多个对象,每个对象有多个过程,因而信息量大,要求学生有较强的阅读能力;②与实验相结合,与生活相结合,要求学生有一定的生活经验和对数据进行分析比较的能力;③所得规律可能在初中物理课本以外,也可能在课本以内;④有定性分析和定量分析两类,定量分析要用到数学上的函数知识.下面通过实例来归纳这类题的一般思考方法.
In recent examinations, the proportion of regular exploratory test questions has increased year by year. These physics test questions generally have the following characteristics: 1 There are multiple objects, and each object has multiple processes. Therefore, the amount of information is large, and students are required to have more information. Strong reading ability; 2 combined with experimentation, combined with life, requiring students to have a certain amount of life experience and the ability to analyze and compare data; 3 the law of income may be in addition to textbooks for junior middle school physics, may also be within the textbook; Qualitative analysis and quantitative analysis are two types. Quantitative analysis requires the use of mathematical knowledge. The following examples are used to generalize the general thinking methods of such questions.
