  In this short note we study Bernstein's type theorem of translating solitons
whose images of their Gauss maps are contained in compact subsets in an open
hemisphere of the standard $\mathbf{S}^n$ (see Theorem 1.1). As a special case
we get a classical Bernstein's type theorem in minimal submanifolds in
$\mathbf{R}^{n+1}$ (see Corollary 1.2).
