问题描述：
what great fun it is to go hiking in such fine weather!和what a great fun .!哪个对?为什么?
答
前一个对，因为 fun 为不可数名词，前面不能用不定冠词 a 修饰。故前者对。
答
第2个
fun抽象名词具体化,且前面有形容词修饰,需要加冠词,类似的有success,wrong,right等.
答
what great fun it is to go hiking in such fine weather!对
fun 不可数名词,不能加a,语法错误
还有,原句后半句应该是……such a fine weather!
