alc24“ 1 What am I bid for this fine vase?

3 I found on your computer what i found on mine.
I Found what you found on your computer on mine. ”
alc24 “but for some reason 1 sounds off, its seems to me that its missing a word?
What am I ___ bid... (I don't know)
and
isn't number 2a wrong? WHAT TELLS ME SHE'S SERIOUS, isn't that like a
translation from french; said that way, wouldn't it be HOW DO YOU KNOW
SHE'S SERIOUS...”
Everything here is correct, in my opinion.
I know the active and passive voice forms of the verb "to bid" seem a little strange, but (trust me 
) that's the way it is. "I bid (to you) $25." (active voice)
"I am bid (by you) $25." (passive voice)
I can't think of a word you can stick in between. "What am I now bid for this"?????
Re 2a, personally, I have nothing against the French. Some of my best friends are French. Two of my most memorable girlfriends were half French.
I'll grant you, 2a is not the most common way to ask this question, but in the proper context, it would be perfect. When we are forced to use only the most common expressions, I, for one, shall be looking for a new home.
