Although Shelly was not invated to the party,she would very

Although Shelly was not invated to the party,she would very much have liked to have gone.
改错,最后 have gone 为什么错

尽管句子本身比较复杂,但是你的问题却不复杂.to have gone表示go动作完成“已经去了”；而to go表示还未进行的动作“想去”.
句子的意思是：尽管Shelly没有被邀请去晚会,但她本来很喜欢去（事实上是没有去）.would have liked是虚拟语气,“本来喜欢、本来想”
另外：invited打错了.
