In this paper, we study the entanglement between two-neighboring sites and
the rest of the system in a simple quantum phase transition of 1D transverse
field Ising model. We find that the entanglement shows interesting scaling and
singular behavior around the critical point, and then can be use as a
convenient marker for the transition point.
