问题描述：
we consider____the machine should be adjusted each time it is used
A.that it necessary B.necessary it that
答
错了吧,应该是,we consider it necessary that the machine...哦，是我看错了B选项应该是it necessary that，为什么选B啊这个【主语we】【谓语 consider】【宾语 it】【宾语补足语 necessary】【同位语从句 that~】其实这个it是形式宾语，that~~所带才是真正地宾语 而第一个应该是：We consider 【that it is necessary~】这个that直接在consider后面，引导宾语从句，后面要有it is 完整的句子。 希望帮到你~
