  In this paper, the continuity of solutions for elliptic equations in
divergence form with distributional coefficients is considered. Inspired by the
discussion on necessary and sufficient conditions for the form boundedness of
elliptic operators by Maz'ya and Verbitsky (Acta Math., 188, 263-302, 2002 and
Comm. Pure Appl. Math., 59, 1286-1329, 2006), we propose two kinds of
sufficient conditions, which are some Dini decay conditions and some integrable
conditions named Kato class or $K^{1}$ class, to show that the weak solution of
the Schr\"{o}dinger type elliptic equation with distributional coefficients is
continuous and give an almost optimal priori estimate. These estimates can
clearly show that how the coefficients and nonhomogeneous terms influence the
regularity of solutions. The $\ln$-Lipschitz regularity and H\"{o}lder
regularity are also obtained as corollaries which cover the classical De
Giorgi's H\"{o}lder estimates.
