已知m,n,l是三条不同的直线，$\alpha ,\beta ,\gamma$是三个不同的平面，给出以下命题：
①若$m\subset \alpha ,n//\alpha$，则m//n； ②若$m\subset \alpha ,n\subset \beta ,\alpha \perp \beta ,\alpha \cap \beta =l,m\perp l$，则$m\perp n$；③若$n//m,m\subset \alpha$，则$n//\alpha$；④若$\alpha //\gamma ,\beta //\gamma$，则$\alpha //\beta$．
其中正确命题的序号是（   ）
