$\Lambda$CDM-like models with future singularities
  We consider new models of dark energy with finite time future singularities,
by introducing the pressure density as a function of the scale factor. This
approach gives acceptable phenomenological models of dark energy, practically
indistinguishable from the cosmological constant up to the present, which face
future singularities at finite time and finite scale factor. Exact scalar field
model representation was found for quintessence, Big Rip and type III
singularity models. The simple form of the equation of state allows to
establish a relationship between its current value, $w_0$, and the time or
redshift at which the singularity takes place. The effect on the growth of
matter perturbations was calculated.
