ZERO AND FIRST CONDITIONAL

ZERO AND FIRST CONDITIONAL

1. THE FIRST CONDITIONAL

   • It's used to talk about things which might happen in the future. Of course, we can't know what will happen in the future, but this describes possible things, which could easily come true
     • if + present simple, ... will + infinitive
       • She'll be late if the train is delayed
     • THE ZERO CONDITIONAL
       • This conditional is used when the result will always happen. So, if water reaches 100 degrees, it always boils. It's a fact. I'm talking in general, not about one particular situation. The result of the 'if clause' is always the main clause.
         • If + present simple, .... present simple.
           • People die if they don't eat.
