  The rotations of the polarization angle (PA) with time (energy) can lead to
the depolarization of the time-integrated (energy-integrated) polarization.
However, we don't know how and when it will rotate. Here, we consider the
magnetic reconnection model to investigate the polarizations, especially the PA
rotations of GRB prompt emission. For the large-scale ordered aligned magnetic
field configuration, we find that PAs will evolve with time (energy) for
off-axis observations. Our studies show that the rotations of the PAs are due
to the changes of the ``observed shape'' of the emitting region (before
averaged). We apply our models to the single pulse burst of GRB 170101A and GRB
170114A with time-resolved PA observations. We find it can interpret the
violent PA variation of GRB 170101A. The model could not predict the twice
$90^{\circ}$ PA changes in GRB 170114A. Detailed model should be considered.
