Recently, a new method, which can significantly speed up adiabatic quantum state transfer by using dressed states, was proposed by Baksic et~al. [Phys. Rev. Lett. 116, 230503 (2016)]. Assisted by quantum Zeno dynamics, we develop this dressed-state method to achieve shortcuts to complete and fractional stimulated Raman adiabatic passage for speeding up adiabatic two-atom quantum state transfer and maximum entanglement generation, respectively. By means of some numerical simulations, we determine the parameters used in the scheme which can guarantee the feasibility and efficiency both in theory and experiment. Besides, we give strict numerical simulations to discuss the scheme's robustness, and the results show the scheme is robust against the variations in the parameters, atomic spontaneous emissions and the photon leakages from the cavity.
