函数(一次函数、反比例函数、二次函数)是初中数学知识的核心内容,是历年各地中考的必考考点,年年考,年年都有设计新颖、创意独特的创新题,命题者往往以课本或学生熟悉的学具为载体,或将考查知识以新的方式呈现(如新定义、阅读理解),令人耳目一新,现采撷几例赏析,供参考.一、相伴学习的学具问题 Functions (one-time function, inverse proportion function, quadratic function) are the core contents of junior middle school mathematics knowledge. They are the necessary test points for the middle school entrance examinations over the years. Every year, there are innovative and unique creative problems. Textbooks or students familiar with the learning as a carrier, or examination of knowledge in a new way (such as the new definition, reading comprehension), refreshing, now pick several appreciation, for reference.
