Query: Generalized BFT Formalism of Electroweak Theory in the Unitary Gauge   We systematically embed the SU(2)$\times$U(1) Higgs model in the unitary
gauge into a fully gauge-invariant theory by following the generalized BFT
formalism. We also suggest a novel path to get a first-class Lagrangian
directly from the original second-class one using the BFT fields.
