In order to realize quantum teleportation efficiently, a new scheme for quantum teleportation of atomic qubit states was presented based on entangled cavity fields. This scheme was realized based on the interaction between a single three-level atom in high quality light cavity and light field under large detuning. The effect of the damping of cavity field on quantum teleportation was discussed. The result shows that one atomic state is transmitted directly to another atom without help of auxiliary atoms in this scheme, efficiency of quantum teleportation reaches 100% in case of ideal light cavity and fidelity of quantum teleportation is close 1.0 for any the transmitted states in case of small damping.
