In　this　paper,　a　weak　Galerkin　(WG　for　short)　finite　element　method　is　used　to　approximate　nonlinear　stochastic　parabolic　partial　differential　equations　with　spatiotemporal　additive　noises.　We　set　up　a　semi-discrete　WG　scheme　for　the　stochastic　equations,　and　derive　the　optimal　order　for　error　estimates　in　the　sense　of　strong　convergence.
