By using the soft pion theorem in the inclusive reactions, soft pions'contribution to the structure function $F_2$ in the nucleon is estimated. It isshown that this contribution produces such a large flavor asymmetry in thelight sea quark distributions that it gives about $30\sim 50 %$ of the NMCdeficit in the Gottfried sum.Comment: 9 pages, 2 figures, to be published in the Prog.Theor.Phy
