  We study a model of scalar field with kinetic terms non-minimally coupled to
to the curvature, and the scalar field coupled to the Gauss Bonnet
4-dimensional invariant. A variety of solutions are found, giving rise to
different cosmological scenarios. A unified description of early time matter
(radiation) dominance with transitions to late time quintessence and phantom
phases have been made. Among others, we found solutions unifying asymptotically
the early power law behavior and late time cosmological constant. Solutions of
Chaplygin gas and generalized Chaplygin gas cosmologies have also been found.
