英文摘要：

In this paper, we study the existence of three solutions for Neumann boundary value problem with impulses. By using a very recent three critical points theorem, we obtain a new criterion for guaranteeing that Neumann boundary value problem with impulses has three solutions. Some recent results are generalized and significantly improved. Some examples are also presented to illustrate our main results.
