Please examine these three sentences.
1) As his son grew older, he resembled his father more and more.
2) As his son grew older, more and more he resembled his father.
3) As his son grew older, he more and more resembled his father.
I have learned that only the first sentence is correct in terms of the position of more and more.
How about the other ones? Does the second or third one sound awkward?
They all sound awkward.
It's not clear who is growing to resemble whom.
If you start with 'As the son grew older. . .' 1 and 3 are OK.
