%X Various shadowing aspects of nuclear parton distributions are discussed in a parton-model framework. We explain existing x dependent data of F2A /F2D, then the model is applied to a flavour asymmetry &#8211; d in a nucleus, to shadowing in valence-quark distributions, and to nuclear dependence of Q2 evolution. First, we find that a finite nuclear &#363; &#8211; &#273; distribution could be possible due to nuclear interactions even in the flavour symmetric case in the nucleon ( &#363; &#8211; &#273; = 0). Second, it is indicated that valence-quark shadowing could be used for discriminating among various shadowing models. Third, we find that nuclear dependence of Q2 evolution &part; &#91;F2Sn/F2C&#93;/&part;&#91;ln Q2&#93;, which was found by the New Muon Collaboration (NMC), is essentially understood by modification of parton distributions in nuclei. However, higher-twist effects in nuclear interactions could be tested by studying the details of the nuclear Q2 evolution.
