从不, 永不, 从来没有
I can never understand why Mary said nothing about her wrongs.
Neighbours are said never to agree.
He never intended to use this method.
Never having seen him before, I did not know what he looked like.
I hope never to see him again.
Never have I seen such a strange person.
There is never a friend but he remembers the birthday of.
I have never been abroad, neither[nor] have I ever wished to go.
He never behaves honestly, nor wisely.
You can tell him now, remember better late than never.
Never mind the expense!
