The two radio bursts from SGR 1935+2154 detected by cite{BKRMHB} and
cite{2020arXiv200510324T} are similar to the features of cosmological fast
radio bursts (FRBs). In this paper, we try to clarify that whether these two
radio bursts are FRBs. First, we compare these two radio bursts with previous
observations of normal pulsars and magnetars, and find that these two radio
bursts should be emitted from positions different from that of radio pulses of
normal pulsars/magnetars. Furthermore, we infer that if
radio/X-ray/$gamma$-ray bursts of an magnetar are emitted from these
positions, an extra torque will exert on the magnetar so that an extra
increment will contribute to the glitch of a magnetar (no matter the glitch
originates mainly from a starquake or a catastrophic superfluid vortex
unpinning.), and a precession will be induced. We argue that these two radio
bursts don’t have the same origin with cosmological FRBs by discussing the
cause of formation of periodically repeating FRBs at last.
