This document discusses the different types of conditionals in English: - The zero conditional uses the present simple for things that are always or usually true, like "If you heat water, it boils". - The first conditional uses the present simple and future will to talk about possible future events, like "If you say run, I will run with you". - The second conditional uses the past simple and would/could to talk about hypothetical situations in the present, like "If I saw you in heaven, I would know your name". It also notes that "were" is normally used with all subjects in the second conditional.

1. CONDITIONALS
(3ºESO)

2. ZERO CONDITIONAL
(Present Simple+ Present Simple)
This is used for things that are always true (logical results of the “if”
clause) and it is formed from the present simple+present simple:
If you heat water, it boils
You can also use it for habits or things that usually happen:
If I have a headache, I take an Ibuprofen
*Finally, you can find a zero conditional to give instructions or invitations which
depend on certain condition (present simple+imperative):
If you want my future, forget my past.
(Wannabe by the Spice Girls)

3. FIRST CONDITIONAL
(PRESENT SIMPLE +FUTURE WILL)
• This is used to talk about future possibilities and is formed using
Present Simple+ the future WILL.
• If you say run, I will run with you (Let’s Dance- David Bowie)

4. SECOND CONDITIONAL
(PAST SIMPLE + WOULD/COULD)
It is used for hypothetical situations in the present and is
formed using Past Simple + Would/Could + infinitive
Would you know my name if I saw you in heaven?
If I saw you in heaven, of course I would know your name.
Tears in Heaven, Eric Clapton
Don’t forget that the order of the ‘if’ clause and result clause
is flexible, so we could also say:
If I saw you in heaven, would you know my name?
Of course I would know your name if I saw you in heaven.

5. SECOND CONDITIONAL
(PAST SIMPLE + WOULD/COULD)
WE NORMALLY USE “WERE” WITH ALL SUBJECTS WHEN WE
ARE USING THE SECOND CONDITIONAL. “WAS” IS ALSO VALID
FOR “I”, “HE”, “SHE”, “IT”, BUT IT USUALLY SOUNDS A LITTLE
“POSH”
If she were my daughter, I wouldn’t let her drop out of school.
If I were you, I wouldn’t trust him.
If they were really interested in the offer, they would contact you.
