  The relation between the nuclear EMC effect and the nucleon-nucleon
short-range correlation is a hot topic in high-energy nuclear physics, ever
since a peculiar linear correlation between these two phenomena discovered. In
this paper, the contribution to the nuclear EMC effect arising from the
short-range correlated nucleons is examined in a nucleon-swelling model. We
find that the structure modifications of the N-N SRC nucleons reproduce more or
less the measured EMC ratios of light nuclei, while they are not enough to
explain the measured EMC ratios of heavy nuclei. We speculate that the
hypothesis of causal connection between SRC and the EMC effect is not exact, or
the universality of the inner structure of SRC nucleon is violated noticeably
from light to heavy nuclei, or there are other origins for the EMC effect.
