随着素质教育的深入,在数学中考试题中渗透其他学科知识,即将试题与初中政治、物理、化学等学科有机结合,已逐渐成为当今考试热点.因此,我们在初一数学学习中,应适当渗透其他学科知识以拓宽知识面,提高我们学习数学的兴趣,培养思维能力,逐步适应中考新形势.请看下面两道中考题目.例1 国家规定个人发表文章,出版图书获得稿费的纳税计算方法是：(1)稿费不高于800元的不纳税；(2)稿费高于800元又不高于4000元应缴纳超过800元部分稿费的14％的税；超过4000元,应纳全部稿费的11％的税.今知丁老师获得一笔稿费,并缴纳个人所得税420元,问丁老师的这笔稿费有多少元?分析：此例涉及初中政治课中内容,不仅提前向我们进行了纳税意识的培养,还具体介绍了稿费的个人所得税缴纳办法.解：4000×11％=440>420,显然丁老师的稿费高于800元而不足4000元. With the deepening of quality education, infiltration of other subject knowledge in the examination questions in mathematics, that is to say, the organic integration of test questions with the subjects of junior middle school politics, physics, chemistry, etc., has gradually become the focus of today’s examination. Therefore, we should be appropriate in the first year of mathematics learning. Infiltrate other subject knowledge to broaden knowledge, improve our interest in learning mathematics, develop thinking skills, and gradually adapt to the new situation in the examination. Please see the following two examination topics. Example 1 State stipulates individuals to publish articles, and tax calculation methods for publishing books to obtain royalties Yes: (1) Non-paying tax is not more than 800 yuan; (2) 14% tax is more than 800 yuan and not more than 4,000 yuan; more than 4,000 yuan is required to cover all draft fees 11% of the tax. This year, Mr. Zhiding received a draft fee and paid personal income tax of 420 yuan. He asked Ding’s how many yuan of this draft fee? Analysis: This case involves the content of the junior high school political class, not only to us in advance. The training of taxpayers’ awareness has also introduced the individual income tax payment method for draft fees. Solution: 4000×11%=440>420. It is apparent that Ding’s draft fee is higher than 800 yuan and less than 4,000 yuan.
