Nowadays, mathematical communication nearly exists in every corner of human communication activities and has already become the indispensible tool of human existence and development in such an informative and mathematical era. Promoting the cultivation of college students' communication ability is the trend of the college mathematical teaching development. The major ways of cultivating college students' mathematical communication ability are as follows: firstly, promoting the cultivation of mathematical language ability to build a solid foundation for mathematical communication ability, secondly creating a democratic "teaching mathematics" atmosphere to supply the development of mathematical communication ability with a good training environment, thirdly exploring materials of the "writing mathematics" to build a free space for the individual development of students' mathematical communication ability and fourthly, guiding students to develop the habit of "reading mathematics" to widen their mathematical communication vision and develop their communication ability.
