• We use the zero conditional when we are 100% sure of a fact (scientific)

• We use the first conditional: - To discuss possible or probable future events. - To make promises and give warnings.

• We use the second conditional: - To discuss imaginary situations in the present. - To discuss imaginary or improbable events in the future.

• We use the third conditional to discuss hypothetical past events (which didn't happen)

• Conditionals with modals

• as long as, even if, providing that, unless

• We can use unless to mean if...not in negative conditional setences.

• We can use even if instead of if to show that the result will not be affected by the condition.

• We can use providing that or as long as (usually in first conditional setences) to mean but only if.

• Example: Crime levels will continue to fall as long as we keep the same number of police officers.  

• Example: We'll be late unless we leave now  

• Example: The workers will strike even if their wages are increased.
