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.
