Conditionals are statements which server us like conditions or decisions taken over a situation.
In philosophy , the result of the conditionals is α→β.
In English , we have four conditions clauses:
!:
En las gramáticas inglesas, exisiten dos tipos de teoría en las condiciones distintas como las vamos a ver a continuación.
- Present Real Conditional (1st or 0 Conditional ).
If present simple, present simple
If my mother cooks the dinner, she servers it
- Future Real Conditional (2nd or 1st Conditional)
If present simple, future simple
Ex:
If my mother cooks the dinner, she will server it
- Future Unreal Conditional (3rd or 2nd Conditional)
If past simple, would+ infinitive
Ex:
If my mother cooked the dinner, she would server it
- Present Unreal Conditional (4th or 3rd Conditional)
If present simple, would+ infinitive
Ex:
If my mother cooks the dinner, she would server it
Special cases with past simple in conditionals sentences
- Past Real Conditional (1st or 0 Conditional)
If past simple, past simple
Ex:
If my mother cooked the dinner, she servered it
- Past Unreal Conditional (2nd or 1st Conditional)
If past simple, would + have+ past perfect
Ex:
If my mother cooked the dinner, she woud have servered it
!:
If the conditional sentence finishes with β, don't use coma before α.
Ex:
My mother serves the cook if she cooks it
