Conditional sentences

The conditional sentences are sometimes confusing for learners of English.
Watch out:
1) Which type of the conditional sentences is used?
2) Where is the if-clause (e.g. at the beginning or at the end of the conditional sentence)?
There are three types of the if-clauses.
typecondition
Icondition possible to fulfill
IIcondition in theory possible to fulfill
IIIcondition not possible to fulfill (too late)
