表语从句问题

— Don't you think it necessary that he _____ to Miami but to New York?
— I agree, but the problem is ______ he has refused to.

[ ]

A. will not be sent; that
B. not be sent; that
C. should not be sent; what
D. should not send; what
为什么要用最后是refused to 第一空懂了，第二问不懂。。求解释

Answer 1

前面是宾语从句，it 是形式宾语，后面的从句才是真正的宾语。
necessary that 后面应该加虚拟语气，所以是(should) not be sent

后面一句的意思是：我同意，但问题是他已经拒绝此事了。
这是省略句，应该是：but the problem is that he has refused to (be sent to New York).

能否详解一下表语从句。。 “再根据答语结构可知是表语从句，并且从句中不缺成分” 这是北京四中网校的解释。。。从句中不缺成分什么意思？。。谢谢

追答

the problem（主语） is （系动词）that he has refused to（表语从句）.
其实纠结到底选what还是that，和是否是表语从句没关系，因为不管是what引导还是that引导，它都是表语从句。区别在于what代表句子中的成分，而that不占成分，是纯粹的引导词。

从句是he has refused to. 这是省略后的完整句子，这就是不缺成分的意思。
如果是what引导，应该写成the problem is what he has refused.

不过我觉得这道题的关键在理解。就算写成了what he has refused，翻译过来意思是不通的：
我同意，但问题是他拒绝了什么。
这句话就不如“但问题是他已经拒绝去纽约了”意思通顺。

。。。。he has refused to为什么是完整句子啊？。。是因为refuse的关系吗？这里是不是还有一个知识点啊？。。。

追答

因为和前一句相同的部分省略掉了。
he has refused to (not be sent to Miami but New York)。

就如同我们说：
Do you want to go to school?
No, but I have to. ( = I have to go to school).

Can you pass me that book?
No, I refuse to. (= I refuse to pass you the book).

我还是建议你从理解句意方面考虑这道题。

Answer 2

填哪个要根据具体语境，联系上下文，单独一句话的话填哪个都说得通
“That is why...”是常用句型， 意为“这就是……的原因/因此……”， 其中why引导的名词性从句在句中作表语， 该句型通常用于针对前面已经说明过的原因进行总结。
“That is because...”句型中从属连词because引导的名词性从句在此作表语， 这也是个常用句型， 意为“这就是为什么……/因为……”。

“That is because...”与“That is why...”之间的不同在于“That is because...”指原因或理由， “That is why...”则指由于各种原因所造成的后果,例如i was late for the appointment.That's becoz i met with an old friend on the way.我约会迟到了，因为我在路上碰到一位老朋友
i met with an old friend on the way,and that's why i was late for the appointment.我在路上碰到一位老朋友，因此我约会迟到了

Answer 3

refuse to 后面的内容被第二个空替代了啊，如果不要第二根横线，直接说就是
I agree,but the problem is that he has refused to be sent to New York
