Models based on the gauge group SU(2) x U(1) x U'(1) are constructed as alternatives to the standard model. These lead naturally to an effective Lagrangian for neutrino-hadron scattering that is identical to the standard model. The electron-quark interactions can be chosen to yield the correct result for polarized electron-deuterium asymmetry measured at SLAC, while permitting a small value for parity violation in bismuth. Definitive tests for these models are the y dependence of the asymmetry in electron-deuterium and electron-proton deep inelastic scattering, which should be fairly rapid, and the assignment of e/sub R/ to a doublet, which can be tested in neutrino-electron scattering. Other tests of the models are also considered. A different version of the model predicts all results identical to the standard model of small q/sup 2/, but allows a lighter Z boson. Models that are not strictly natural are also discussed. 19 references, 4 figures.
