问题描述：
it is no use (persuading) him because he will never change his mind.这里的动名词
persuading他的逻辑主语是谁?求分析句子成分,为什么用动名词形式,不要用固定用法概括,
答
It is no use(形容当时的情况,在句子里算是形容词) persuading (动词) him (名词) because he(名词) will never change(动词) his mind(被动名词).no use是形容词？形容当前状况的都是形容词？我说的分句子成分是分主语和谓语什么的说no use 是形容词也不完美，其实它是像谚语一样的，翻译过来就是 白搭。固定出现时一般为 Of no use, It's no use. etc.
