I have read the following conversation:
—Have you finished your homework? —__. Just half of it．How about you?
The options for the blank are the followings:
A．Not at all
C．Not a bit
I will choose the D option. I would like to complement all these options as followings:
Not at all.= I haven't finished my homework at all.
Not a bit. = I haven't finished my homework a bit.
Not yet. = I haven't finished my homework yet.
What confused me most is that I don't know how to complement "Not likely."
(1) I haven't likely finished my homework.
(2) It is not likely to have finished my homework.
Which sentence is correct? Why and why not?
