This is our English teacher,_____ I think is a kind man 填什么,为什么,

问题描述:

This is our English teacher,_____ I think is a kind man 填什么,为什么,
为什么不用of whom think及物吗?

who这是我英语老师,我认为他是个善良的人
_____ I think is a kind man,其实这个句子可以变成I think _____ is a kind man,要填上一个作主语的词,先行词是our English teacher指人,所以要填who 而不用of whom
