the man whose duty it is to help me为什么这里要有 it不是the man whose duty is to help me

问题描述:

the man whose duty it is to help me
为什么这里要有 it
不是
the man whose duty is to help me

the man whose duty is to help me

原始错误 不应该有it`
有也应该是that is to help me

应该是the man whose duty is to help me,除非中间有一个"that"

你看错或者打错了吧?加了it根本不符合英语语法,会不会是你的资料错误了?
