I mean the meaning of COULDN'T HAVE DONE and CAN'T HAVE DONE ? Can you explain ?
If I can't or couldn't have done something, that means that it was not possible for me to do it, that the possibility is excluded.
Use can't or cannot for the very recent past, and couldn't or could not for the more remote past.
I couldn't have stolen the money six months ago, I was in another town that day.
I can't have eaten all the cakes this morning, I was still in bed!
John can't have eaten his breakfast. He is gone, and the food is still on the plate.
Mary can't have taken her car. The keys are still on the table.
And i also have one more question .
Does MISS + TO VERB exist ?[/quote]
What, like "In winter I miss to see the sun"?
No, with the verb to miss, you use a participle "In winter I miss
seeing the sun" (Or just I miss the sun)
I love to see the sun. I miss seeing it. I love to kiss pretty girls. Now I am in jail, i miss kissing girls.
