We have proposed a model Hamiltonian, which describes a simple physical picture that the holes with single occupation constraint introduced by doping move in the antiferromagnetic background of the copper spins, to describe the normal state of the cuprate superconducting materials, and used the renormalization group method to calculate its anomalous magnetic and transport properties. The anomalous magnetic behavior of the normal state is controlled by both the copper spin and the spin part of the doping hole residing on the O sites. The physical resistivity is determined by both the quasiparticle-spin-fluctuation and the quasiparticle-gauge-fluctuation scatterings and the Hall coefficient is determined by the parity-odd gauge interaction deriving from the nature of the hard-core boson which describes the charge part of the doping holes.
