we are very sorry that the airport will have to be closed for about 12 hours.that可省

题目

we are very sorry that the airport will have to be closed for about 12 hours.that可省
that可省略么? 如果省略那后面就是一个主语从句?我不会分析这样的句子～!应该怎么分析?
that引导的宾语从句么?可省啊应该!如果要是we are very sorry the airport will have to be closed for about 12 hours.呢?还需要加什么所有格么?

答案

这是一个宾语从句.
当主句的谓语动词是be 动词时,that 不可以省略.
