Soft gamma-ray repeaters are at determined distances and their positio
ns are known accurately. If observed, afterglows from their soft gamma
-ray bursts will provide important clues to the study of the so called
''classical gamma-ray bursts''. On applying the popular fireball/blas
twave model of classical gamma-ray bursts to soft gamma-ray repeaters,
it is found that their x-ray and optical afterglows are detectable. M
onitoring of the three repeaters is solicited.
