It做形式宾语问题。He feels it his duty to help others.如果不用形式宾语，好像说不通He feels his duty to help others.在his duty 后面加个is就痛了

Answer 1

he主语 feels谓语 it形式宾语 his duty名词做补语 to help others真正宾语
如果改成宾语从句，则为：He feels that it is his duty to help others
这里it为宾语从句中的形式主语to do不定式作真正的宾语

Answer 2

he主语 feels谓语 it形式宾语 his duty名词做补语 to help others真正宾语。
he feels（that）his duty is to help others.

He feels his duty to help others.或者说：He feels his duty to help others.
