what fun it is!有what加名词+主语+谓语!这样的结构吗?

What a ____(fun)story it is! what fun it is to=how____ 为什么是what fun it is to. What good weather it is?是否有语法错误?还有What fun the story is what fun day it is?为什么用fun,不用funny 如题What fun it is中fun是什么 what fun it is!有what加名词+主语+谓语!这样的结构吗? what fun it is 有没有错.what 后面不是要加名词吗? what fun it is! 这个fun前面是不是要加a或者what改fun? 英语fun有形容词意么?what fun it is to go swimming?what 可以用how 替代么 为什么是what great fun it is!而不是what a great fun it is! what is your fun fun what is this? 英语的fun可数吗?是What a great fun it is!还是What great fun it is! what a fun和how fun的用法是what a fun it is to do sth还是how fun ? What fun it is 和How fun it is 后面加doing还是to do What fun it is How fun it is ,怎么用,仔细点 为什么说what fun it is!而不用how fun it is?这是什么句型?
