I think it necessary that we take plenty of hot water every day .是用it作形式宾语的宾语从句

问题描述:

I think it necessary that we take plenty of hot water every day .是用it作形式宾语的宾语从句
那么I think it necessary to do sth,加不定式这种形式可以吗?

加不定式也是可以的,只是that后是跟从句.换不定式后句子是这样的,
I think it necessary for us to take plenty of hot water every day.
