Transcript of Conditional Clauses



OPEN CONDITIONS

The condition could be fulfilled or not, they can imply uncertainty

HYPOTHETICAL CONDITIONS

They talk about unreal situations, imaginary events, things that will probably not happen.

General facts
* They are used to show conditions and hypothesis about the past, present and future.

* Conditional sentences have two parts: "the if clause" and "the main clause".

* They are interchangeable; when the if clause comes first, a comma separates them.
special cases
Conditionals express lots of things: desires, wishes, regrets, complaints etc. but to express hypothesis we don't only use conditionals and they don't only start with a conjunction.
Inversion
Sometimes the conjunction "if" is omitted and an inversion of the auxiliary occurs.

a) with should
If you should run into him, tell him I'm here / should you run into him, tell him I'm here.
b) 3rd type
If I had seen her, I would have talked to her/
Had I seen her, I would have talked to her
c) 2nd type with were
If I were your mother, I would tell you off./
Were I your mother, I would tell you off.
d) 1st type ( both clauses joined with "and"

touch me again and I'll hit you
