Scientific paper

We review some modified gravity models which describe the gravitational dark
energy and the possibility of cosmic speed-up. The new consistent version of
such theory which contains inverse and HD curvature terms as well as new type
of coupling with matter is proposed. The accelerating cosmologies are discussed
there. The structure of finite-time (sudden) singularities is investigated.
