Question

write a five exclamatory sentences beginning with. what and how

Answer 1

Hi, I have this question about "how" and "what" in exclamation sentences.
We can say: 
1. "how beautiful he is."
2. "how beautiful a boy he is."
3. "what a beautiful boy he is."
4. "what beautiful boys they are."

However, we can't say: 
5. "how beautiful boys they are."

I know it's because "how" can only modify adjectives or adverbs and since "beautiful boys" forms a unit as a noun phrase, we can not say 
"how beautiful boys they are."

But "boys" can also be a syntactic constituent.
So how do we explain the inappropriateness of the sentence "how beautiful boys they are"? 
Is there any good explanation in linguistics, syntactically or pragmatically?

Thank you.
