求that后面的语法解释

Answer 1

that后面的句子就是前面it的指代内容
他不会被送到武汉而是北京 but在这里就不能翻译成但是了 不过也表示除了一种转折

追问

that后面不应该是一个从句么？我觉得应该是he was not be…

Answer 2

it是形式宾语，而that引导的从句才是真正的宾语(从句)。

追答

it's necessary that...

追问

that后面不应该是一个从句么？我觉得应该是he was not be…

追答

该结构中，that从句常常采用虚拟语气

追问

should省略了是么！

追答

即从句的谓语由 should do构成，且should可以省略

对

he not be..
= he should not be...

求采纳，谢谢！
