本文是特级化学教师赵德民先生为新高三学生而写的。他指出了在暑假中同学们要抓紧时间,打好化学知识基础,提高使用知识、技能解决新情景中新问题的能力,为迎接来年的高考做好准备。文章提出“两种反应三个表”,意在让同学们运用三个表来说明两种反应,并通过做练习题检查自己理解和应用的程度。这是行之有效的训练措施,定会帮助同学提高不少应用能力。 This article was written by Mr. Zhao Demin, a special chemistry teacher, for a new junior high school student. He pointed out that during the summer vacation, students must seize the time, lay a good foundation for chemical knowledge, and improve their ability to use knowledge and skills to solve new problems in the new situation. This will prepare them for the next year’s college entrance examination. The article puts forward “two types of responses in three tables”, which are intended to allow students to use the three tables to illustrate the two types of responses, and to examine the level of understanding and application through doing exercises. This is an effective training measure that will surely help students improve their application skills.
