        Tratando de ayudar a los estudiantes a conocer un poco más sobre la grámatica de la lengua extranjera "Inglés", aquí les proporciono una información muy completa acerca de los diferentes tipos de "Condicionales" (Conditionals) así como una serie de actividades para lograr un mejor entendimiento de ellos.

Conditional Sentences

We use conditional sentences when we want to say that something is the consequence of, or depends on, something else, they can be divided into if clauses and result clauses:


      If it rains,                 I will get wet.

The if clause can come first or second in a sentence.


EX. If it rains, I will get wet. (With comma)

I will get wet if it rains. (Without comma)

Zero conditional.

We use zero conditional when we are talking about things that are generally

 true all the time and that are real. In this type of conditional, we use the present

simple in both clauses. If can be replaced whit when:


EX.   The dog runs away if we leave the door open.

      (NOTE: we can use the continuous form in a zero conditional: When I am running, I always get out of breath.)


First conditional.


We use it when are talking about something which may possibly happen in the

future. In this type of conditional sentence, we usually choose will for the

consequence clause, with the if clause in the present simple:


EX.    If I lose my job, I will emigrate.


(NOTE: we can use the continuous form in a zero conditional)

Second conditional.

We use it to talk about the consequence of impossible or unlikely events or situations in the present or future, or an unreal condition. They are hypothetical because they probably won't happen. The verb pattern is past simple in the if clause and would + infinitive in the consequence clause:

          If there was a war,        the stock marker would boom.

We often use the subjunctive form were in place of was in the if clause, especially in phrases giving advice:

EX.    If I were you, I wouldn't spend so much clothes.

*If we use was, it sounds a little bit more informal.

Third conditional.

We use it to talk about the consequence of impossible events or situations. They are impossible because they occurred in the past and therefore cannot be changed - except hypothetically. The construction pattern is past perfect in the if clause and would (would not) + have + past participle in the consequence clause:

          If I had run a lot              I would started coughing.
We can use other auxiliary verbs like could, might, etc. (instead of would) in the consequence clause:

EX.    If he hadn't known how to swim, he could have drowned.

The consequence of a third conditional if clause can occur in the present or the future too:

EX.    If she hadn't met him on vacation, she wouldn't be getting married to him later this year.
         If he had studied Mandarin a bit harder, he'd be able to speak it better.
