虚拟语态中省略的问题

You should have thanked her before you left.

I meant to, but when i was leaving i couldnt find here.

老师请问在这个问题中 为何可以省略have.

而： Why didnt you take part in my birthday party yesterday?

I would like to have, but I had an unexpected guest.

在这个问题中为何正确答案是 to have 而不能像上一个一样是to呢？

You should have thanked her before you left.

I meant to, but when i was leaving i couldnt find here.

这个对话中，meant to是不适合的。应改为had meant to 或者 meant to have。

第二个对话中，would like to have是正确的。
