We present one of the results of $BVRI$ photometry of the hosts of GRB forthe host galaxy of GRB 970508 and the theoretical modeling of its continuumspectral energy distribution (SED) to show that it is important to take intoaccount internal extinction in the host galaxies. We compared the BVRIbroad-band flux spectrum of the host to template SEDs of local starburstgalaxies and found that there is a significant internal extintion in this host.Moreover, this comparison allows us to derive the absolute magnitude(M_{B_{rest}}) and rouhgly estimate reddening (A_V). Population synthesismodeling of the continuum SED for different reddening laws demostrates that theobservational data of the host galaxy of GRB 970508 are best fitted by thespectral properties of a model SED with extinction of A_V\approx 2.Comment: 3 pages, 2 figures, poster presentation on 2nd Rome Workshop on  Gamma-Ray Bursts in the Afterglow Er
