A new Lagrangian of EW interactions without spontaneous symmetry breaking, Higgs, and Fadeev-Popov procedure has been constructed. It consists of three parts: SU(2)L× U(1) gauge fields, massive fermion fields, and their interactions. In this theory the gauge coupling constants g, g', and fermion masses are the inputs. A new mechanism of SU(2)L× U(1) symmetry breaking caused by fermion masses has been found. In the EW theory top quark mass plays a dominant role. This mechanism leads to nonperturbative generation of the gauge fixings and masses of Z and W fields. m2W=1\over2g2 m2t, m2Z=1\over2g2 m2t, GF=(1)/(2√(2)m2t) are revealed from this theory. The propagators of Z- and W-fields without quadratic divergent terms are derived. Very heavy neutral and charged scalars are dynamically generated from this theory too.
