Abstract: Limit thinking is one of the most basic of mathematical thinking in the mathematics learning process, the limits of thought has a fairly wide range of applications, especially in mathematical analysis of learning there is a clear expression. Limit way of thinking and solving math problems is particularly important, the methods used by the special title cases are not the same. This article describes the limits of the basic definitions, lists the basic solution of the limit problem, and limit the promotion of a little understanding. 

Key words: Limit thinking; common method; the promotion and application of limit;
