近年来,随着对培养学生能力的日益重视,涌现出了许多既注重基础知识考查,又有利于能力训练的好题型。其中有一种题型的突出特点是题目中给出一个中学生曾未学过,而又与中学化学内容联系密切的新知识——一个原理、一个反应过程或一种方法等。要求学生在阅读题目的过程中很快掌握,并能和自己已有的知识经验熔为一体,运用于解决具体化学问题的实践中去。由于它既要求基础知识很熟练,又要求迅速处理新信息,综合性强,能力要求较高,使许多学生颇感棘手。本文将结合几个例题说明这类题的解答方法。
In recent years, with the increasing emphasis on the ability to train students, many good questions have emerged that focus on basic knowledge examination and benefit training. One of the prominent features of the question type is that the title gives a new knowledge that has not been studied by middle school students yet is closely related to the chemical content of middle school—a principle, a reaction process, or a method. Students are required to quickly grasp the process of reading the topics and integrate them with their own knowledge and experience, which can be used to solve specific chemical problems. Because it requires both basic knowledge and skill, it also requires rapid processing of new information. It has a high level of comprehensiveness and high ability requirements, which makes many students very difficult. This article will explain the solution to this type of problem with several examples.
