We study the contributions for the and
originating from the intermediate states
and
in the charmless three-body decays
, with
, in the perturbative QCD approach. The subprocesses
are introduced into the distribution amplitudes of
system via the kaon electromagnetic form factors with the coefficients taken from the fitted results. The predictions of the branching fractions for the decays
with the intermediate state
decays into
or
are about
of the corresponding results for the quasi-two-body decays
in this work.
