高中英语感叹句

1.——these ancient buildings in this city are!

A.What perfectly protected B.How perfect protected C.How perfectly protected D.What perfect protected
问题:为什么选C不选A
感叹句讲义中说“如果中心词是可数的复数名词和不可数名词只能用what”,这里中心名词不是buildings嘛,为什么不选A
2.-What sport do you like best?
---Springboard diving.______to dive into water from hign board!
A.What fun it is B.How fun it is
为什么选A不选B好多人书what fun it is 其中的fun 为不可数名词后面接动词应该为doing,这里不是to do吗?难道网上的错了?

1、这一个句子的中心词不是名词,而是过去分词protected(相当于形容词),所以感叹词是how

比较一下 

    How perfectly protected these buildings are!

    What perfectly protected buildings these are!

    How beautitul these girls are!

    What beautiful girls these are!


2、这一题关键是fun是名词(不可数的),所以就选A。

What fun it is! = How enjoyable it is!


It is fun doing sth. 是标准的句式,无可挑剔。它来自 doing sth. is fun。

It is fun to do sth. 也可以接受,但有争议。

追问

为什么fun在此不能是形容词?
adj.
使人愉快的;开心的

追答

fun 有形容词的用法,但此时它只作定语(且前置),不作表语。
如:There are lots of fun things to do here. (fun 作定语)
