would like/love to have done 与would have liked/loved to do用法解析
一、.expect,want, mean, intent, plan, hope,consider,wish,promise,suppose,think、design、desire等动词可以用来表示过去想要、打算、计划、希望做某事，但实际未做。有以下二种形式：

二、具体到would like/love to do 想要做某事
would like中的would是委婉说法，并不表示过去，而是表示现在希望做某事，后接to do不定式表示将来要做的事，还没有发生。
would like to have done=would have liked to do含义相同；因此:
Much as I would like to stay, I really must go home.
I would like to acknowledge my debt to my teachers.
We would like to apologize for the delay.
Lastly, I would like to thank my parents for all their support.
