问题（要解释原因和翻译句子）
1.It is great fun to have a picnic on the hisss-de. What ___ it ___to have have a picnic on the hisssde!
What （great fun__） it （_is_）_to have a picnic on the hisssde! fun是不可数名词，怎么能用a呢？这是感叹句．have a picnic 野餐，此外，what great fun it is to have have a picnic on the hissde! 多了个 have 译文：在hisssde野餐是多么有趣的事情。
1.It is great fun to have a picnic on the hisss-de. What ___ it ___to have have a picnic on the hisssde! 后面的句子有问题吧？怎么两个have？ 感觉应该是： What _great fun__ it is__to have a picnic on the hisssde!
对不起哦，我有一点小疑问 what great fun it is to have a picnic on the hisssde!不对么？似乎不应该加冠词a的
fun是不可数名词，绝对不能用a great fun 感叹句： what great fun it is to have have a picnic on the hissde! 第一个have表完成时，第二个是have a picnic 固定短语，野餐的意思。
.It is great fun to have a picnic on the hisss-de. What a great fun it _is__to have have a picnic on the hisssde! 在hisssde野餐是多么有趣的事情。 这是把普通句型改为感叹句型
