• Abstract: Segmented function is a difficult point in function teaching, but if teachers are good at infiltrating segmented function into function teaching, they can not only make students have a deeper understanding of segmented function, but also broaden students’ understanding of the concept of function and the monotony, parity and periodicity of function. 分段函数在函数教学中是个难点，但如果教师善于将分段函数渗透在 函数教学中，不仅能使学生对分段函数有更深的理解，同时也能拓宽学生对函 数概念以及函数的单调性、奇偶性、周期性的认识。
