高三化学复习一般分两轮进行:一轮复习主要是将整个高中的化学知识进行梳理、重现,使学生掌握好基础知识;二轮复习时则一般侧重于题型训练,提高解题能力。然而,在二轮复习时我们的学生基础知识真的掌握好了吗?回答是否定的,特别是那些原本基本功就不扎实的学生可以称得上是“老鼠背秤砣,越背越重”。渐渐的,他们会感觉化学很难学,学得很吃力,经过几次失败后,又产生 High school chemistry review generally divided into two rounds: a review is mainly the entire high school chemistry knowledge to sort out, reproduce, so that students have a good grasp of basic knowledge; the second round of review is generally focused on the type of training to improve the ability to solve problems. However, in the second round of review, our students’ basic knowledge really mastered it? The answer is no, especially those who could not be considered basic solid students can be called ". Gradually, they will feel chemistry is difficult to learn, very difficult to learn, after a few failed, they produce
