Short summary
It has been shown that guide fields substantially modify the structure of reconnection layers. In this paper, we studied the electric field structures in magnetic reconnection under different initial guide fields (Bg). Once the amplitude of a guide field exceeds 0.3 times the asymptotic magnetic field B0, the traditional bipolar Hall electric field is clearly replaced by a tripolar electric field, which consists of a newly emerged electric field and the bipolar Hall electric field.

Short summary
Electron energization is an outstanding issue in magnetic reconnection, which is a hot topic in plasma physics and astrophysics. Four different structures have been proposed for electron energization during reconnection. We find that there is no specific sequence of electron energization through the four structures; there is no specific order of electron acceleration efficiency among the four structures, and electron energization occurs in a wide region around X-line.
