  We report and propose a simple scheme to achieve the ultrafast and selective
population transfer in four-level atoms by utilizing a single frequency chirped
few-cycle pulse. It is demonstrated that the almost complete population may be
transferred to the preselected state of atoms just by manipulating the so
called chirp offset parameter. The robustness of the scheme against the
variation of laser pulse parameters is also investigated. The proposed scheme
may also be useful for the selective population transfer in molecules.
