  In this paper we study the low temperature behaviors of a system of
Bose-Fermi mixtures at two dimensions. Within a self-consistent ladder diagram
approximation, we show that at nonzero temperatures $T\rightarrow0$ the
fermions exhibit non-fermi liquid behavior. We propose that this is a general
feature of Bose-Fermi mixtures at two dimensions. An experimental signature of
this new state is proposed.
