The conditional sentences are sometimes confusing for learners of English, for Spanish learners the problem comes when you try to translate our ‘subjunctive’..
There are three types of the if-clauses.
|I||condition possible to fulfill|
|II||condition in theory possible to fulfill|
|III||condition not possible to fulfill (too late)|
|type||if clause||main clause|
present/ will-future (or Modal + infinitive)/ imperative IF I STUDY I PASS/ WILL PASS THE EXAM
would + infinitive *
IF I STUDIED I WOULD PASS THE EXAM
would + have + past participle *
IF I HAD STUDIED I WOULD HAVE PASSED THE EXAM
* We can substitute could or might for would (should, may or must are sometimes possible, too).
If can be replaced by words or expressions with a similar meaning.
as long as
on condition (that)
on the assumption (that)
with the condition (that)
