In no way do I...
Barely had I...
Not only... But
Had I known...
Rarely will you see...
Rarely do we...
On no account should you...
Never before have I...
Not for one moment did I think...
Seldom do I...
Only later...
Under no circumstances...
Not until...
Only by working hard...
No sooner had I...
Hardly ever do I...
Nowhere have I ever...
Were I the president...
