This may result in your saying almost nothing.中的"your saying

是呀，高中英语教师，喜欢语法。

动名词的复合结构（one's doing sth）作主语时只能用物主代词的形容词型，your,my,her,等；作宾语时，可以用宾格取代，you--your,me--my,her--her,him--his等。 Would you mind my smoking here? Would you mind me smoking here? Would you mind Li Ping's smoking here? Would you mind Li Ping smoking here? His coming late made his teacher angry.His coming late 在这里是主语，不可以用宾格取代。 Li Ping's coming late made his teacher angry.Li Ping's coming late 在这里是主语，也不可以用Li Ping 取代。 所以，Your saying is almost nothing 才是对的。
