____________________
A future tense, instead of a present tense, is possible for universal facts, but it is not so common. I shall only include the commoner alternative in this key, that is, the one in the present tense.
Contractions may be used.
Was (
not) is informal.
The conditional clause may be placed after the main one:
You'll overwind the clock if they don't stop winding it. The same applies to the other answers in this part.
