In this paper, we study the entanglement between two neighboring sites and the rest of the system in a simple quantum phase transition of a one-dimensional transverse field Ising model. We find that the entanglement shows interesting scaling and singular behaviors around the critical point, and thus can be used as a convenient marker for the transition point.
