CONDITIONALS

CONDITIONALS

1. ZERO CONDITIONAL

   • This type of conditional is used to describe things that will always be true when the condition of the 'if' clause is met.
   • The same verb form is used in both parts of the sentence: the simple present tense.
   • The zero conditional is used for scientific facts and things we are certain of. The meaning of this kind of sentence remains the same if 'when' is substituted for 'if'.

2. FIRST CONDITIONAL

   • Although the action is in the future, the condition clause must be in the present tense.
   • This type of conditional is used to talk about things that we believe will happen in the future.
   • In a first conditional sentence, we use the present simple verb form for the condition clause, then 'will' and the infinitive for the result.
   • We don't know what will happen in the future, but the first conditional is used to discuss things things that are likely to happen.
   • We don't know what will happen in the future, but the first conditional is used to discuss things things that are likely to happen.

3. SECOND CONDITIONAL

   • The second conditional is used to talk about impossible and imaginary situations in the future.
   • In a second conditional sentence, we use the past simple for the condition clause, then 'would' and the infinitive for the result.
   • Although the action is in the future, the condition clause must be expressed in the past tense. The words 'should', 'could' and 'might' can be used instead of 'would' in a second conditional sentence. If the action described in the result clause is likely to happen, you should use the first conditional instead.

4. THIRD CONDITIONAL

   • In third conditional sentences we talk about situations that did not happen in the past, and what the result would have been.
   • We use the past perfect tense for the condition clause, then 'would have' and the past participle for the result clause.
   • The third conditional always talks about an imaginary past that did not happen.Both the condition and the result must be impossible in a third conditional clause. THIRD CONDITIONAL ANDRES ALAN
