题目

10._______ interesting work it is to teach children!A.How B.How an C.What D.What an

答案

C.做这道题.记住他们俩的结构就可以了、
what a(an)+形容词+名词+主语+谓语.如果其中的名词是不可数名词,把a 或an 去掉即可.
How+形容词+主语+谓语.(how 是修饰形容词的）
例子：what a beautiful girl she is .
how beautiful she is .
因为work是不可数名词,所以只能选C喽.
下面是我摘抄别人的理解.供你参考哦!
在感叹句中:
1."How" 副词性 .
引导感叹句后边只能直接修饰"adj/adv"
2."What" 形容词性
引导感叹句后边可修饰名词/名词短语(含修饰成分的名词)
对比分析
(1)How引导:
You are beautiful .
--How "beautiful"(形容词) you are !
(2)what 引导
You are a beautiful girl .
--What "a beautiful girl"(含修饰成分的名词) you are !
