1a. She knows nothing about him except he is young and handsome.
1b. She knows nothing about him except that he is young and handsome.
2a. The brothers are very alike, except Mohan is slightly taller than Raman.
2b. The brothers are very alike, except that Mohan is slightly taller than Raman.
Are these sentences OK? Please comment.
Thanks.
Usually, ‘nothing’ is followed by ‘but’.
Though I have also seen sentences similar to yours, I would use your sentences as follows:
She does not know anything about him except that he is young and handsome.
Except for the fact that Mohan is slightly taller than Raman, both the brothers are almost alike.
The brothers are almost alike, except for the difference that one is slightly taller than the other.
Mohan and Raman, who are brothers, look almost alike, but the former is slightly taller than the latter. (This, of course, is a very formal statement)
I’m sure you will find the revised ones useful for a comparative study.
1a Use 1b
1b correct and natural.
2a Use 2b
2b correct and natural.
The expanded suggestions are unnecessary.
