the child's playing video games 还是the child playing video ga

选the child playing video games 玩视频游戏的孩子.playing video games是定语.
即使the child's playing video games理解成所有格形式,也只能选后者,如果选前者,句子就成了The child's playing video games made his mother very angry.主语成了“playing video games ”,那his mother中的his作为主语所有格,就不是“孩子的”,反而成了“玩游戏的”了.
