Cu´l es la estructura de del tercer condicional
Foro de Inglés
Like the other conditionals, a third conditional sentence consists of two clauses, an "if" clause and a main clause:
|if clause||main clause||explanation|
|If I had studied harder,||I would have passed the exam.||I failed the exam, because I didn"t study hard enough.|
If the "if" clause comes first, a comma is usually used. If the "if" clause comes second, there is no need for a comma:
|main clause||if clause|
|I probably would have passed the exam||if I had studied harder.|
We use different verb forms in each part of a third conditional:
|if clause||if + subject + past perfect verb*|
|main clause||subject + would (OR could, OR might) have + past participle|
*The past perfect is formed with the auxiliary verb "had", and the past participle (or third form) of the verb.
Note also that third conditional forms can be contracted:
|Full form||If I had studied harder, I probably would have passed the exam.|
|Contracted form||If I"d studied harder, I probably would"ve passed the exam.|
Using the third conditional
The third conditional is used to talk about things which DID NOT HAPPEN in the past. If your native language does not have a similar construction, you may find this a little strange, but it can be very useful. It is often used to express criticism or regret.
Indica una condicion en el pasado, que ya on se puede cumplir.
If + Past perfect + conditional perfect (would have)
If we had been more careful, we wouldn't have had de accident.
Si hubiesemos sido mas cuidadosos, noi habrìamos tenido el accidente.
