答
in the face = in the direction of the face 朝着脸的方向飞过来 这个是特殊情况下才这么用（句中有指示是飞过来）
on the face 就是在脸上 一般都是这么用，
答
你这里是在说在身体不同部位上要用不同的介词：
vt.+sb. in/on/by +the +身体部位
take/pull/grasp/seize/catch/hold/lead sb. by the ear/nose/ hand/arm/sleeve
hit/strike/touch/pat sb. in the face/eye/ stomach/ side/chest/
hit/strike/touch/pat sb. on the head/ shoulder/ nose/ neck/ back
答
hit in the face 是打中脸部范围内,通常指击中的范围比较小
hit on the face 打中的范围比较大
当然,只是相对而言,不必太执着
