长期以来,中考之后,考生普遍认为物理难。如果教师在考前学生的训练中将错综复杂的物理现象,形形色色的物理题型加以分类归纳,逐一总结,概括为相应的解题规律——以不变应万变,就可以突破常规的解题方法,化繁为简,从而增强学生的解题信心。在中考试题中,有些综合难题,根据物理现象的内在联系,用比例关系解决比较方便,而且容易切入试题,争 For a long time, after the entrance exam, candidates generally think that physics is difficult. If the teacher in the exam training students intricate physical phenomena, all kinds of physical types to be summarized, one by one summarized, summarized as the corresponding problem-solving law - the same should be changed, you can break the conventional problem-solving Methods, simplification, thereby enhancing the students confidence in solving problems. In the middle school exam questions, some comprehensive problems, according to the internal relations of physical phenomena, the proportion of relations to solve more convenient, and easy to cut into the test questions
