Condicionales

Hay tres tipos de condicionales.

Tipo 1 :

1. Presente - presente : se usa para hechos generales que no cambian leyes o hechos científicos. Ejemplos : (If you take drogs regulary you become addicted to them.

2. Presente en futuro : Se usa principalmente para posibilidades futuras. Ejemplos : (Unless you study, you won’t pass your exams.)

Tipo 2 :

Se usan para condiciones imposibles o muy difícil de conseguir en el presente o en el futuro. También se usan para dar consejos y sugerencias.

Expresión :

If + past, would + inf.

If I were rich, I would buy a yatch.

If Mary were hear now, se would drive me home.

If I were you, I wouldn’t marry him.

Nota : en este tipo de oraciones el to be pasado se utiliza were para todas las personas.

Tipo 3 :

Es usada par cosas irreales o imposibles en el pasado :

Expresión :

Past perfect / conditional perfect.

Have + p.p / would + have + p.p

Ejemplos :

We would have gone abroad for our holidays if we hadn’t bought a new car.

If We hadn’t set out, We wouldn’t have been caught in the traffic jam.

If you had listened to your father you wouldn’t have made many mistakes.

Nota : unless significa a no ser que.

Otor punto de vista es: Algunas gramáticas establecen categorías en las oraciones condicionales tales como "Condicional probable, improbable, posible" etc). Para los hispanohablantes, entiendo, es más sencillo establecer las equivalencias con las condiciones en español. En el cuadro que aparece a continuación expongo todos los tiempos verbales implicados en la realización de las condicionales. Hay que tener en cuenta algo importante:

No importa el orden de la condición. Ejemplo: Es lo mismo decir "Si viene a la fiesta lo pasaremos bien" que decir "Lo pasaremos bien si viene a la fiesta".

La condición positiva se expresa en inglés con IF y la negativa con UNLESS (si no)

 

 

 

|IF |TIEMPO 1 |TIEMPO 2 |MODELO |

|IF |PRESENTE |PRESENTE |IF YOU STUDY YOU PASS YOUR EXAMS |

|IF |PRESENTE |IMPERATIVO |IF YOU WANT, COME TO THE PARTY |

|IF |PRESENTE |FUTURO |IF YOU COME, YOU WILL SEE HER |

|IF |PASADO |CONDICIONAL |IF YOU SOLD YOUR CAR, YOU WOULD GET MUCH MONEY |

|IF |PLUSCUAM. |COND. COMPUES. |IF YOU HAD COME TO THE PARTY, YOU WOULD HAVE SEEN HER |

  Traducción:

1.- Si estudias, pasas tus exámenes (if+pres+pres)

2.- Si quieres, ven a la fiesta (if+pres+imperativo)

3.- Si vendieras tu coche, ganarías mucho dinero (if+pasado+condicional)

4.- Si hubieras venido a la fiesta, le habrías visto (if+pluscuamperfecto+condicional compuesto).

 

  Unless:

UNLESS + VERBO AFIRMATIVO= IF + VERBO NEGATIVO
