  In this work, we discuss the possibility of studying nucleon resonances in
the $K^+N$ interactions. Based on our model calculations, it is found that the
hyperon exchange plays an important role for the excitation of nucleon
resonances in the $K^+N$ interactions. Therefore, the studies on nucleon
resonance production in the $K^+N$ interactions can offer us valuable
information about the couplings of nucleon resonances with strange particles.
By selecting suitable decay channels of nucleon resonances, some reactions are
also suitable to look for missing resonances.
