Conditionals

Many visitors and subscribers ask us: I was told there are three or four conditionals in English, but I suppose I know just one. It is true, there exist THREE different types of conditional sentences in English. Let's study them here... Muchos visitantes y suscriptores nos consultan: Me dijeron que hay tres o cuatro tipos de condicionales pero creo saber sólo uno. Es cierto, básicamente existen CUATRO tipos de condicionales en inglés que analizamos aquí... conditional type 0 >> ZERO CONDITIONAL                              IF  + SIMPLE PRESENT  +  SIMPLE PRESENT Used for scientific facts or general truths (usado para expresar verdades científicas, hechos que nunca cambian o situaciones que siempre ocurren). Algunos gramáticos incluyen este tipo de condicional dentro de FIRST CONDITIONAL o Conditional Type I. If you heat butter, it melts. Si calientas manteca, ésta se derrite.

If you cross an international date line, the time changes. Si cruzas una línea de tiempo internacional, la hora cambia. If you drop ice in water, it floats. Si tiras hielo al agua, éste flota. If iron gets wet, it rusts. Si el hierro se moja, se oxida. conditional type I >> FIRST CONDITIONAL                              Used to talk about things which are possible in the present or the future.

NOTE: In cases a and c above, you can replace IF (si) by UNLESS (a menos que) conditional type II >> SECOND CONDITIONAL          Used to talk about things which are unreal (not true or not possible) in the present or the future. It is generally used for things which don't or won't happen. It is generally used for things which may happen (utilizado en presente o futuro para expresar situaciones hipotéticas, que normalmente son irreales o imposibles). IF  +  SIMPLE PAST  +  SIMPLE CONDITIONAL  If FIRST verb in the sentence is TO BE, WERE is used for all persons.  (Si el PRIMER verbo de la oración es TO BE, se usa WERE para todas las personas) If I were rich, I would buy a castle. Si fuera rico, compraría un castillo.

(utilizado para expresar situaciones irreales – que nunca sucedieron – en el pasado y, en general, dentro de un contexto de crítica, queja o remordimiento). En español tienes una construcción similar por lo cual este condicional no debería resultar complicado.
