Abstract: The non-linear nature of string theory on non-trivial backgrounds related to the AdS/CFT
correspondence suggests to look for simplifications. Two such simplifications proved to be
useful in studying string theory. These are the pp-wave limit which describes point-like
strings and the so called ``near flat space'' limit which connects
two different sectors of string theory -- pp-waves and ``giant magnons''.
Recently another example of AdS/CFT duality emerged - $AdS_4/CFT_3$,
which suggests duality between $\mathcal N=6$ CS theory and superstring theory on $AdS_4\times \cp$.
In this paper we study the ``near flat space'' limit of strings on the $AdS_4\times \cp$ background
and discuss possible applications of the reduced theory.
